Spinal Cord: A cylindrical column of tissue that lies within the vertebral canal. It is composed of WHITE MATTER and GRAY MATTER.Anesthesia, General: Procedure in which patients are induced into an unconscious state through use of various medications so that they do not feel pain during surgery.Anesthesia: A state characterized by loss of feeling or sensation. This depression of nerve function is usually the result of pharmacologic action and is induced to allow performance of surgery or other painful procedures.Anesthesia, Spinal: Procedure in which an anesthetic is injected directly into the spinal cord.Anesthesia, Local: A blocking of nerve conduction to a specific area by an injection of an anesthetic agent.Spinal Cord Injuries: Penetrating and non-penetrating injuries to the spinal cord resulting from traumatic external forces (e.g., WOUNDS, GUNSHOT; WHIPLASH INJURIES; etc.).Anesthesia, Epidural: Procedure in which an anesthetic is injected into the epidural space.Anesthesia, Inhalation: Anesthesia caused by the breathing of anesthetic gases or vapors or by insufflating anesthetic gases or vapors into the respiratory tract.Anesthesia, Conduction: Injection of an anesthetic into the nerves to inhibit nerve transmission in a specific part of the body.Anesthesia, Intravenous: Process of administering an anesthetic through injection directly into the bloodstream.Anesthesia, Obstetrical: A variety of anesthetic methods such as EPIDURAL ANESTHESIA used to control the pain of childbirth.Anesthesia Recovery Period: The period of emergence from general anesthesia, where different elements of consciousness return at different rates.Anesthesia, Dental: A range of methods used to reduce pain and anxiety during dental procedures.Injections, Spinal: Introduction of therapeutic agents into the spinal region using a needle and syringe.Anesthetics, Inhalation: Gases or volatile liquids that vary in the rate at which they induce anesthesia; potency; the degree of circulation, respiratory, or neuromuscular depression they produce; and analgesic effects. Inhalation anesthetics have advantages over intravenous agents in that the depth of anesthesia can be changed rapidly by altering the inhaled concentration. Because of their rapid elimination, any postoperative respiratory depression is of relatively short duration. (From AMA Drug Evaluations Annual, 1994, p173)Anesthetics, Intravenous: Ultrashort-acting anesthetics that are used for induction. Loss of consciousness is rapid and induction is pleasant, but there is no muscle relaxation and reflexes frequently are not reduced adequately. Repeated administration results in accumulation and prolongs the recovery time. Since these agents have little if any analgesic activity, they are seldom used alone except in brief minor procedures. (From AMA Drug Evaluations Annual, 1994, p174)Adjuvants, Anesthesia: Agents that are administered in association with anesthetics to increase effectiveness, improve delivery, or decrease required dosage.Propofol: An intravenous anesthetic agent which has the advantage of a very rapid onset after infusion or bolus injection plus a very short recovery period of a couple of minutes.

Propofol has been used as ANTICONVULSANTS and ANTIEMETICS.Anesthetics, Local: Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate.Spinal Nerves: The 31 paired peripheral nerves formed by the union of the dorsal and ventral spinal roots from each spinal cord segment. The spinal nerve plexuses and the spinal roots are also included.Spinal Cord Diseases: Pathologic conditions which feature SPINAL CORD damage or dysfunction, including disorders involving the meninges and perimeningeal spaces surrounding the spinal cord.

The drugs need not be in the same dosage form.Spinal Nerve Roots: Paired bundles of NERVE FIBERS entering and leaving the SPINAL CORD at each segment. The dorsal and ventral nerve roots join to form the mixed segmental spinal nerves. The dorsal roots are generally afferent, formed by the central projections of the spinal (dorsal root) ganglia sensory cells, and the ventral roots are efferent, comprising the axons of spinal motor and PREGANGLIONIC AUTONOMIC FIBERS.Monitoring, Intraoperative: The constant checking on the state or condition of a patient during the course of a surgical operation (e.g., checking of vital signs).Spinal Cord Neoplasms: Benign and malignant neoplasms which occur within the substance of the spinal cord (intramedullary neoplasms) or in the space between the dura and spinal cord (intradural extramedullary neoplasms).

The most frequent histologic types of intradural-extramedullary tumors are MENINGIOMA and NEUROFIBROMA.Spinal Canal: The cavity within the SPINAL COLUMN through which the SPINAL CORD passes.Nitrous Oxide: Nitrogen oxide (N2O). A colorless, odorless gas that is used as an anesthetic and analgesic. High concentrations cause a narcotic effect and may replace oxygen, causing death by asphyxia. It is also used as a food aerosol in the preparation of whipping cream.Spinal DiseasesSpinal Cord Compression: Acute and chronic conditions characterized by external mechanical compression of the SPINAL CORD due to extramedullary neoplasm; EPIDURAL ABSCESS; SPINAL FRACTURES; bony deformities of the vertebral bodies; and other conditions. Clinical manifestations vary with the anatomic site of the lesion and may include localized pain, weakness, sensory loss, incontinence, and impotence.Anesthetics: Agents that are capable of inducing a total or partial loss of sensation, especially tactile sensation and pain. They may act to induce general ANESTHESIA, in which an unconscious state is achieved, or may act locally to induce numbness or lack of sensation at a targeted site.Spinal NeoplasmsLidocaine: A local anesthetic and cardiac depressant used as an antiarrhythmia agent. Its actions are more intense and its effects more prolonged than those of PROCAINE but its duration of action is shorter than that of BUPIVACAINE or PRILOCAINE.Halothane: A nonflammable, halogenated, hydrocarbon anesthetic that provides relatively rapid induction with little or no excitement. Analgesia may not be adequate. NITROUS OXIDE is often given concomitantly. Because halothane may not produce sufficient muscle relaxation, supplemental neuromuscular blocking agents may be required. (From AMA Drug Evaluations Annual, 1994, p178)Spinal Stenosis: Narrowing of the spinal canal.Bupivacaine: A widely used local anesthetic agent.Spinal Fusion: Operative immobilization or ankylosis of two or more vertebrae by fusion of the vertebral bodies with a short bone graft or often with diskectomy or laminectomy.

(From Martindale, The Extra Pharmacopoeia, 30th ed, p1078)Anesthesia, Closed-Circuit: Inhalation anesthesia where the gases exhaled by the patient are rebreathed as some carbon dioxide is simultaneously removed and anesthetic gas and oxygen are added so that no anesthetic escapes into the room. Closed-circuit anesthesia is used especially with explosive anesthetics to prevent fires where electrical sparking from instruments is possible.Nerve Block: Interruption of NEURAL CONDUCTION in peripheral nerves or nerve trunks by the injection of a local anesthetic agent (e.g., LIDOCAINE; PHENOL; BOTULINUM TOXINS) to manage or treat pain.Anesthetics, General: Agents that induce various degrees of analgesia; depression of consciousness, circulation, and respiration; relaxation of skeletal muscle; reduction of reflex activity; and amnesia. There are two types of general anesthetics, inhalation and intravenous. With either type, the arterial concentration of drug required to induce anesthesia varies with the condition of the patient, the desired depth of anesthesia, and the concomitant use of other drugs. (From AMA Drug Evaluations Annual, 1994, p.173)Ketamine: A cyclohexanone derivative used for induction of anesthesia. Its mechanism of action is not well understood, but ketamine can block NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE) and may interact with sigma receptors.Ambulatory Surgical Procedures: Surgery performed on an outpatient basis.

(Adams et al., Principles of Neurology, 6th ed, p1089)Spinal Cord Ischemia: Reduced blood flow to the spinal cord which is supplied by the anterior spinal artery and the paired posterior spinal arteries. This condition may be associated with ARTERIOSCLEROSIS, trauma, emboli, diseases of the aorta, and other disorders. Prolonged ischemia may lead to INFARCTION of spinal cord tissue.Pentobarbital: A short-acting barbiturate that is effective as a sedative and hypnotic (but not as an anti-anxiety) agent and is usually given orally. It is prescribed more frequently for sleep induction than for sedation but, like similar agents, may lose its effectiveness by the second week of continued administration. (From AMA Drug Evaluations Annual, 1994, p236)Anesthetics, Dissociative: Intravenous anesthetics that induce a state of sedation, immobility, amnesia, and marked analgesia. Subjects may experience a strong feeling of dissociation from the environment. The condition produced is similar to NEUROLEPTANALGESIA, but is brought about by the administration of a single drug. (From Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed)Ganglia, Spinal: Sensory ganglia located on the dorsal spinal roots within the vertebral column.

Dose-response effects of spinal neostigmine added to bupivacaine spinal anesthesia in volunteers. (1/609)BACKGROUND: Intrathecal adjuncts often are used to enhance small-dose spinal bupivacaine for ambulatory anesthesia. Neostigmine is a novel spinal analgesic that could be a useful adjunct, but no data exist to assess the effects of neostigmine on small-dose bupivacaine spinal anesthesia. METHODS: Eighteen volunteers received two bupivacaine spinal anesthetics (7.5 mg) in a randomized, double-blinded, crossover design. Dextrose, 5% (1 ml), was added to one spinal infusion and 6.25, 12.5, or 50 microg neostigmine in dextrose, 5%, was added to the other spinal. Sensory block was assessed with pinprick; by the duration of tolerance to electric stimulation equivalent to surgical incision at the pubis, knee, and ankle; and by the duration of tolerance to thigh tourniquet. Motor block at the quadriceps was assessed with surface electromyography. Side effects (nausea, vomiting, pruritus, and sedation) were noted. Hemodynamic and respiratory parameters were recorded every 5 min. Dose-response relations were assessed with analysis of variance, paired t tests, or Spearman rank correlation. RESULTS: The addition of 50 microg neostigmine significantly increased the duration of sensory and motor block and the time until discharge criteria were achieved. The addition of neostigmine produced dose-dependent nausea (33-67%) and vomiting (17-50%). Neostigmine at these doses had no effect on hemodynamic or respiratory parameters. CONCLUSIONS: The addition of 50 microg neostigmine prolonged the duration of sensory and motor block. However, high incidences of side effects and delayed recovery from anesthesia with the addition of 6.25 to 50 microg neostigmine may limit the clinical use of these doses for outpatient spinal anesthesia.

Transdermal nitroglycerine enhances spinal sufentanil postoperative analgesia following orthopedic surgery. (2/609)BACKGROUND: Sufentanil is a potent but short-acting spinal analgesic used to manage perioperative pain. This study evaluated the influence of transdermal nitroglycerine on the analgesic action of spinal sufentanil in patients undergoing orthopedic surgery. METHODS: Fifty-six patients were randomized to one of four groups. Patients were premedicated with 0.05-0.1 mg/kg intravenous midazolam and received 15 mg bupivacaine plus 2 ml of the test drug intrathecally (saline or 10 microg sufentanil). Twenty to 30 min after the spinal puncture, a transdermal patch of either 5 mg nitroglycerin or placebo was applied. The control group received spinal saline and transdermal placebo. The sufentanil group received spinal sufentanil and transdermal placebo. The nitroglycerin group received spinal saline and transdermal nitroglycerine patch. Finally, the sufentanil-nitroglycerin group received spinal sufentanil and transdermal nitroglycerine. Pain and adverse effects were evaluated using a 10-cm visual analog scale. RESULTS: The time to first rescue analgesic medication was longer for the sufentanil-nitroglycerin group (785+/-483 min) compared with the other groups (P<0.005). The time to first rescue analgesics was also longer for the sufentanil group compared with the control group (P<0.05). The sufentanil-nitroglycerin group group required less rescue analgesics in 24 h compared with the other groups (P<0.02) and had lesser 24-h pain visual analog scale scores compared with the control group (P<0.005), although these scores were similar to the sufentanil and nitroglycerin groups (P>0.05). The incidence of perioperative adverse effects was similar among groups (P>0.05). CONCLUSIONS: Transdermal nitroglycerine alone (5 mg/day), a nitric oxide generator, did not result in postoperative analgesia itself, but it prolonged the analgesic effect of spinal sufentanil (10 microg) and provided 13 h of effective postoperative analgesia after knee surgery.

Assessing introduction of spinal anaesthesia for obstetric procedures. (3/609)To assess the impact of introducing spinal anaesthesia for obstetric operative procedures on use of general anaesthesia and quality of regional anaesthesia in a unit with an established epidural service a retrospective analysis of routinely collected data on method of anaesthesia, efficacy, and complications was carried out. Data were collected from 1988 to 1991 on 1670 obstetric patients requiring an operative procedure. The introduction of spinal anaesthesia in 1989 significantly reduced the proportion of operative procedures performed under general anaesthesia, from 60% (234/390) in 1988 to 30% (124/414) in 1991. The decrease was most pronounced for manual removal of the placenta (88%, 48/55 v 9%, 3/34) and emergency caesarean section (67%, 129/193) v 38%, 87/229). Epidural anaesthesia decreased in use most significantly for elective caesarean section (65%, 77/118 v 3% 3/113; x2=139, p<0.0001). The incidence of severe pain and need for conversion to general anaesthesia was significantly less with spinal anaesthesia (0%, 0/207 v 3%, 5/156; p<0.05). Hypotension was not a problem, and the incidence of headache after spinal anaesthetic decreased over the period studied. Introducing spinal anaesthesia therefore reduced the need for general anaesthesia and improved the quality of regional anaesthesia. (+info)
Incidence of bradycardia during recovery from spinal anaesthesia: influence of patient position. (4/609)We administered 0.5% plain bupivacaine 4 ml intrathecally (L2-3 or L3-4) in three groups of 20 patients, according to the position in which they were nursed in the post-anaesthesia care unit (PACU): supine horizontal, 30 degrees Trendelenburg or hammock position (trunk and legs 30 degrees elevated). Patients were observed until anaesthesia descended to less than S1. The incidence of severe bradycardia (heart rate < 50 beat min-1) in the PACU was significantly higher in patients in the Trendelenburg position (60%) than in the horizontal (20%, P < 0.01) or hammock (10%, P < 0.005) position. After 90 min, following admission to the PACU, only patients in the hammock position did not have severe bradycardia. In this late phase, the incidence of severe bradycardia in the Trendelenburg group was 35% (P < 0.005) and 10% in patients in the supine horizontal position. In four patients, severe bradycardia first occurred later than 90 min after admission to the PACU. The latest occurrence of severe bradycardia was recorded 320 min after admission to the PACU. We conclude that for recovery from spinal anaesthesia, the Trendelenburg position should not be used and the hammock position is preferred. (+info)
Hyperbaric spinal ropivacaine: a comparison to bupivacaine in volunteers. (5/609)BACKGROUND: Ropivacaine is a newly introduced local anesthetic that may be a useful alternative to low-dose bupivacaine for outpatient spinal anesthesia. However, its relative potency to bupivacaine and its dose-response characteristics are unknown. This double-blind, randomized, crossover study was designed to determine relative potencies of low-dose hyperbaric spinal ropivacaine and bupivacaine and to assess the suitability of spinal ropivacaine for outpatient anesthesia. METHODS: Eighteen healthy volunteers were randomized into three equal groups to receive one spinal administration with bupivacaine and a second with ropivacaine, of equal-milligram doses (4, 8, or 12 mg) of 0.25% drug with 5% dextrose. The duration of blockade was assessed with (1) pinprick, (2) transcutaneous electrical stimulation, (3) tolerance to high tourniquet, (4) electromyography and isometric force dynamometry, and (5) achievement of discharge criteria. Differences between ropivacaine and bupivacaine were assessed with linear and multiple regression. P < 0.05 was considered significant. RESULTS: Ropivacaine and bupivacaine provided dose-dependent prolongation of sensory and motor block and time until achievement of discharge criteria (R2 ranges from 0.33-0.99; P values from < 0.001 through 0.01). Spinal anesthesia with ropivacaine was significantly different from bupivacaine and was approximately half as potent for all criteria studied. A high incidence of back pain (28%; P = 0.098) was noted after intrathecal ropivacaine was given. CONCLUSION: Ropivacaine is half as potent and in equipotent doses has a similar profile to bupivacaine with a higher incidence of side effects. Low-dose hyperbaric spinal ropivacaine does not appear to offer an advantage over bupivacaine for use in outpatient anesthesia. (+info)
Sedation depends on the level of sensory block induced by spinal anaesthesia. (6/609)We have investigated the relationship between the extent of spinal block and occurrence of sedation. In a first series of 43 patients, the distribution of sedation score (measured on the Ramsey scale) was related to the extent of spinal block (pinprick). In a second series of 33 patients, the relationship between sedation score and spinal block persisted after injection of midazolam 1 mg. This study confirmed that high spinal block was associated with increased sedation. (+info)
Anaesthetic management of a woman who became paraplegic at 22 weeks' gestation after a spontaneous spinal cord haemorrhage secondary to a presumed arteriovenous malformation. (7/609)A 19-yr-old woman developed a paraplegia with a T10 sensory level at 22 weeks' gestation. The spinal injury was caused by spontaneous bleed of a presumed arteriovenous malformation in the spinal cord. She presented for Caesarean section at term because of the breech position of her fetus. The successful use of a combined spinal epidural-regional anaesthetic is described and the risks of general and regional anaesthesia are discussed. (+info)
Spinal versus epidural anesthesia for cesarean section in severely preeclamptic patients: a retrospective survey. (8/609)BACKGROUND: Selection of spinal anesthesia for severely preeclamptic patients requiring cesarean section is controversial. Significant maternal hypotension is believed to be more likely with spinal compared with epidural anesthesia. The purpose of this study was to assess, in a large retrospective clinical series, the blood pressure effects of spinal and epidural anesthesia in severely preeclamptic patients requiring cesarean section. METHODS: The computerized medical records database was reviewed for all preeclamptic patients having cesarean section between January 1, 1989 and December 31, 1996. All nonlaboring severely preeclamptic patients receiving either spinal or epidural anesthesia for cesarean section were included for analysis. The lowest recorded blood pressures were compared for the 20-min period before induction of regional anesthesia, the period from induction of regional anesthesia to delivery, and the period from delivery to the end of operation. RESULTS: Study groups included 103 women receiving spinal anesthesia and 35 receiving epidural anesthesia. Changes in the lowest mean blood pressure were similar after epidural or spinal anesthesia. Intraoperative ephedrine use was similar for both groups. Intraoperative crystalloid administration was statistically greater for patients receiving spinal versus epidural anesthesia (1780 +/- 838 vs. 1359 +/- 674 ml, respectively). Neonatal Apgar scores and incidence of maternal intensive care unit admission or postoperative pulmonary edema were also similar. CONCLUSION: Although we cannot exclude the possibility that the spinal and epidural anesthesia groups were dissimilar, the magnitudes of maternal blood pressure declines were similar after spinal or epidural anesthesia in this series of severely preeclamptic patients receiving cesarean section. Maternal and fetal outcomes also were similar. (+info)
Continuous Spinal Anaesthesia is a recognized technique for providing anaesthesia for various surgical procedures. It may be an alternative to general anaesthesia in high-risk elderly patients requiring emergency laparotomy. The objective was to evaluate the benefits of continuous spinal anaesthesia in providing effective anaesthesia for emergency laparotomy, in enhancing recovery after major abdominal surgery and in reducing length of stay in the intensive care unit in high-risk elderly patients. Prospective service evaluation was performed at a tertiary care university hospital. High-risk elderly patients were offered both general anaesthesia and continuous spinal anaesthesia. An 18-gauge macro catheter was inserted into the intrathecal space through a 16-gauge Tuohy needle. Sedation was maintained with remifentanil. Prophylactic anti-emetics were administered. Blood pressure was maintained with an infusion of metaraminol. Over a 27-month period, 25 high risk elderly patients were offered continuous
BACKGROUND: Pre-loading with hetastarch decreases the incidence and severity of hypotension after spinal anesthesia for cesarean delivery. However, pharmacokinetic studies with crystalloid predict that fluid loading should be more efficacious if rapidly administered immediately after induction of spinal anesthesia. The aim of this study was to compare pre- and co-loading of hetastarch for the prevention of hypotension following spinal anesthesia for cesarean delivery.. METHODS: Forty-six healthy term parturients scheduled for cesarean delivery were randomized to receive 500 mL of 6% hetastarch intravenously, either slowly before spinal anesthesia (pre-loading) or as quickly as possible immediately after spinal anesthesia (co-loading). Systolic blood pressure was maintained at or above 90% of baseline with intravenous vasopressor boluses (ephedrine 5mg/mL+phenylephrine 25 microg/mL). The primary outcome was the volume of vasopressor mix required. Secondary outcomes included blood pressure and ...
It is a common observation that following spinal anaesthesia, the penis usually elongates. The aim of this study was to determine the degree of change in penile length following spinal anaesthesia. Consecutive urosurgical patients undergoing spinal anaesthesia were recruited for this study. Those who received general anaesthesia or incomplete spinal blocked were also excluded. The flaccid length of the penis was measured before and after the administration of spinal anaesthesia. Penile length 15 minutes post-spinal anaesthesia was measured and recorded. The change in length was tested for statistical significant difference, the age of patient; diagnosis and type of surgery were also recorded. Forty three patients completed the study. Benign prostatic hypertrophy constituted 41.9% of the surgical indications. While 53.5% of the patients were ASA I, 39.5% and 7.0% of them were ASA II and III respectively. While the mean initial penile length was 12.1 ± 0.53 cm and the mean final length was 15.7 ± 0.53

Spinal anaesthesia (or spinal anesthesia), also called spinal block, subarachnoid block, intradural block and intrathecal block, is a form of regional anaesthesia involving the injection of a local anaesthetic into the subarachnoid space, generally through a fine needle, usually 9 cm (3.5 in) long. For obese patients longer needles are available (12.7 cm / 5 inches). The tip of the spinal needle has a point or small bevel. Recently, pencil point needles have been made available (Whitacre, Sprotte, Gertie Marx and others). Spinal anaesthesia is a commonly used technique, either on its own or in combination with sedation or general anaesthesia. Examples of uses include: Orthopaedic surgery on the pelvis, hip, femur, knee, tibia, and ankle, including arthroplasty and joint replacement Vascular surgery on the legs Endovascular aortic aneurysm repair Hernia (inguinal or epigastric) Haemorrhoidectomy Nephrectomy and cystectomy in combination with general anaesthesia Transurethral resection of the ...

Accepted: 12 March 2018 Abstract. Introduction: The purpose of the present study was to compare the effect of ENTONOX inhalation and spinal injection on the reduction of labor pain, the Apgar score of the neonates, and their side effects on new-born children and pregnant women.. Material and Methods: The present clinical trial study is conducted among the pregnant women in the maternity ward of a child delivery hospital in Iran. All Participants were divided in two groups ENTONOX Inhalation and Spinal Anesthesia. Visual Analogue Scale (VAS) was implemented to measure the pain level experienced by the participants during the procedure. Moreover, the Apgar scale was used to measure the general physical health of the neonates in both groups. In addition, the participants receiving ENTONOX were asked to report the side effects they underwent during gas inhalation. However, the participants in the spinal anesthesia were checked three times. Statistical analysis was performed using SPSS version ...
It is hypothesized that high spinal anesthesia combined with general anesthesia decreases the intraoperative stress and inflammatory response and improve post-operative pain control and respiratory function in this patient population. It is also hypothesized that the technique will provide stable intraoperative hemodynamics during aortic valve replacement surgery.. Stress response: Levels of hormones such as epinephrine, norepinephrine and cortisol are elevated during cardiac surgery and on the initiation of cardiopulmonary bypass. This stress response has previously been shown to be blunted with the use of high spinal anesthesia when combined with general anesthesia in coronary artery bypass surgery patients (Lee, Grocott, et al).. Inflammatory response: In addition to the stress response there is also an accentuated inflammatory response. With contact of the patients blood to the artificial bypass circuit, there is activation of various plasma protease pathways that generate multiple ...
The addition of vasoconstrictors for spinal anesthesia is controversial, since an increase in the incidence of transient neurologic symptoms (TNS) has been reported. A multicenter, randomized, double-blind study was conducted to assess the effectiveness of spinal anesthesia with phenylephrine in addition to tetracaine as well as the incidence of neurological complications. We studied 64 patients with comparable demographic characteristics who were scheduled for elective surgery for a lower limb, or a gynecological or urological procedure. The patients were allocated randomly into 2 groups. Group P (n = 34) received 0.5% tetracaine in 10% glucose with 0.025% phenylephrine, while group C (n = 30) received 0.5% tetracaine in 10% glucose ...
The advantages of spinal anesthesia under certain restrictions are so obvious and the results obtained from its use so excellent that one can appreciate the popularity of this valuable anesthetic measure. However, from time to time, there have appeared in the literature reports of patients who have developed neurological complications occurring immediately after or remotely following the administration of a spinal anesthetic. The statements in the literature are extremely contradictory as to the frequency with which such nervous sequelae occur. Emmett1 reports he had no neurological sequelae in 1415 cases, and Foss and Schwalm2 state that in 3,000 cases they ...

The incidence of spinal anesthesia-induced hypotension in pregnant women undergoing a cesarean section is high. A preoperative fluid bolus of undetermined volume is frequently administered to lower the incidence of maternal hypotension, with a somewhat poor efficacy. Recently, several investigations have shown that the use of a phenylephrine infusion after the induction of spinal anesthesia results in a significant reduction in hypotensive episodes. Given the high efficacy of this therapy (incidence of hypotension around 20%), it is possible to determine the effective volume of fluid which would prevent hypotension in 50% of the patients studied (ED50).. Healthy term pregnant women undergoing elective cesarean section under spinal anesthesia will be recruited in this trial. The spinal anesthesia regimen will be standardized and all subjects will receive a phenylephrine infusion. The fluid investigated is hydroxyethylstarch (HES) 130/0.4 (Volulyte(R)). The ED50 will be determined using an up-down ...
The aim of the study was to review maternal hypotension during caesarean delivery with spinal anesthesia. Obstetric complications, such as obstetric hemorrhage and problems related to concomitant maternal diseases are not considered. Reports of hypotension during spinal anesthesia for elective caesarean delivery are frequent (70-80%) when pharmacological prophylaxis is not used. Although some physical methods (leg wrapping, thromboembolic stockings) and the prevention of aorto-caval compression (left lateral tilt of the uterus) are useful, main prevention relies on two pharmacological methods, vasopressor therapy and intravascular fluid loading generally in combination. Ephedrine has been the vasopressor of choice in obstetrics for decades but phenylephrine is now the preferred first line approach during elective procedures at least. Crystalloid preloading is clinically ineffective and should be abandoned. Crystalloid coloading at the onset of sympathetic blockade is better but its efficacy may ...
Abstract:. Aims: The study was undertaken to search for an alternative technique to preloading with less or no side effects. Settings and Design: A total of 100 female patients of ASA class I and II undergoing abdominal hysterectomy were enrolled in the study. Two groups namely Group A and Group B were made. All the patients received 2.6ml of 0.5% Bupivacaine heavy intrathecally at L3-L4 level in lateral decubitus using 25 gauge Quinckes spinal needle. Patients of Group A were placed in Trendelenberg position after spinal anesthesia and patients of Group B received preloading with Lactated Ringers solution before spinal anaesthesia. Assessment of hemodynamics (intraoperative and post operative) and side effects was done. Statistics: Data are expressed as mean + SD. Group comparisons were made using unpaired t-test. Results: Intraoperative blood loss and intraoperative requirement of Inj. Mephentermine was significantly less in Group A in comparison to Group B. Conclusion: Trendelenberg ...
Spinal anesthesia is a type of neuraxial anesthesia; local anesthetic (LA) is injected into cerebrospinal fluid (CSF) in the lumbar spine to anesthetize nerves that exit the spinal cord. Spinal anesthesia is most commonly used for anesthesia and/or a
In their study, Williams et al. sought to isolate the effect of surgery from that of general anesthesia by retrospectively comparing the cognitive outcomes of a cohort of infants who had undergone a brief surgical procedure under spinal anesthesia to normative data for the population of Vermont. The authors are to be commended for their contribution in assessing whether a surgical procedure may contribute to adverse cognitive outcome later in childhood. The Pediatric Anesthesia & Neurodevelopment Assessment (Columbia) and Mayo Anesthesia Safety in Kids (Mayo) studies, although not randomized controlled trials, will augment the insights gained from the General Anesthesia Spinal Anesthesia (GAS) study now underway at several U.S. and international sites. None, however, will report definitive outcomes for at least two or three years. In the meantime, we must content ourselves with very important but severely limited studies such as that published by Williams et al. in this issue of Anesthesia & ...
Background: To evaluate general anesthesia with sevoflurane vs spinal anesthesia with low dose lidocaine 5% onhemodynamics changes in patients undergoing hip fracture surgery.Methods: In this randomized double blind trial 100 patients (50 patients in each group) older than 60 years underhip surgery were randomized in general anesthesia with sevoflurane and spinal anesthesia with lidocaine 5%.Hemodynamic changes including mean arterial pressure (MAP) and heart rate, blood loss, pain severity, nausea andvomiting and opioids consumption were compared in two groups.Results: During surgery, difference between two groups regarding changes in mean arterial pressure was notsignificant, but the changes in heart rate were significantly different. Mean arterial pressure changes during recoverybetween two groups were significantly different. But there was no significant difference in heart rate changes. Bleedingin the sevoflurane group was significantly more than spinal group (513.ml vs. 365 ml). Moreover, AS Score

The mean arterial pressure was much stable in group A ...
Background: Headache is the most common complication caused by spinal anesthesia. Systematic educational programs about conservative treatments could be effective in the reduction of headache after spinal anesthesiz. Aim: This study aimed to evaluate the effects of training programs on the headache of patients after spinal anesthesia. Method: This empirical study was conducted on 120 patients within the age range of 16-40 years who were candidates for general, orthopedic and urology surgeries in Dr. Shahidzadeh Hospital of Behbahan, Iran in 2015. Patients were randomly divided into two groups of intervention and control. Scheduled training was provided for the intervention group, and the control group received routine training. Intensity of headache was recorded using the visual analogue scale (VAS). Data analysis was performed in SPSS V.14 using Chi-square and independent T-test. Results: In this study, Chi-square test showed a statistically significant difference between the groups in terms of
Among the complications of spinal anaesthesia, 6th cranial nerve palsy occurs rarely. There is a possibility of encountering nerve injury during subarachnoid injections due to a long extracranial course. The symptoms appear as a result of ocular muscle paralysis. These symptoms often begin after the 4th day and spontaneous recovery lasts for weeks to months. We present a case in which Nervous Abducens palsy occurred following spinal anaesthesia for double j ureteral catheter placement surgery..

One of the potential risks of spinal anesthesia is that it fails to achieve adequate surgical anesthesia.(7) More importantly, planning for the management of patients with a failed spinal is arguably one of the most important considerations for the pre-operative discussion and intra-operative management. At Vermont, patients are counseled that in the event that the spinal is not successful, the procedure will be canceled and re-scheduled for a later date. This decision has been reached unanimously between surgeons, anesthesiologists, perioperative nurses, pediatricians and neonatologists. Pediatric anesthesiologists must always be prepared to provide respiratory support to infants following spinal anesthesia. Dr. Williams commented that an important finding of the GAS trial is infant spinal anesthesia can be achieved effectively throughout the world. Regarding the practical aspects, Dr. Williams described experience with tetracaine, ropivacaine, hyperbaric and isobaric bupivacaine. He did not ...
Dilation of lymphatic vessels may contribute to iatrogenic dissemination of cancer cells during surgery. We sought to determine whether neuraxial anesthesia reduces regional lymphatic flow. Using nuclear lymphoscintigraphy, 5 participants receiving spinal anesthesia for brachytherapy had lower extremity lymph flow at rest compared with flow under conditions of spinal anesthesia. Six limbs were analyzed. Four limbs were excluded because of failure to demonstrate lymph flow (1 patient, 2 limbs), colloid injection error (1 limb), and undiagnosed deep vein thrombosis (1 limb). All analyzed limbs showed reduced lymph flow washout from the pedal injection site (range 62%-100%) due to neuraxial anesthesia. Lymph flow was abolished in 3 limbs. We report proof-of-concept that neuraxial anesthesia reduces lymphatic flow through a likely mechanism of sympathectomy ...
Baricity refers to the density of a substance compared to the density of human cerebrospinal fluid. Baricity is used in anesthesia to determine the manner in which a particular drug will spread in the intrathecal space. Solutions that have a baricity approaching 1.000 are referred to as isobaric, as the density of the cerebrospinal fluid is approximately 1.0003+/- 0.0003. Solutions with a baricity less than 0.999 are termed hypobaric, and are usually created by mixing the local anesthetic with distilled water. Hyperbaric solutions are created by mixing dextrose 5-8% with the desired local anesthetic. Hyperbaric solutions will flow in the direction of gravity and settle in the most dependent areas of the intrathecal space. Conversely, hypobaric mixtures will rise in relation to gravitational pull. These properties allow the anesthesia provider to preferentially control the spread of the block by choice of mixture and patient positioning. Barash, Paul G.; Cullen, Bruce F.; Stoelting, Robert K. F ...
Epidural and spinal blocks are types of anesthesia in which a local anesthetic is injected near the spinal cord and nerve roots. It blocks pain from an entire region of the body, such as the belly, the hips, the legs, or the pelvis. Epidural and spinal anesthesia are used mainly for surgery of the lower belly and the legs. Epidural anesthesia is often used in childbirth. But it can also be used to help control pain after major surgery to the belly or chest.. Epidural anesthesia involves the insertion of a hollow needle and a small, flexible catheter into the space between the spinal column and outer membrane of the spinal cord (epidural space) in the middle or lower back. The area where the needle will be inserted is numbed with a local anesthetic. Then the needle is inserted and removed after the catheter has passed through it. The catheter remains in place. The anesthetic medicine is injected into the catheter to numb the body above and below the point of injection as needed. The catheter is ...
Background and Aims: Many unilateral lower limb orthopedic surgeries are conducted under unilateral spinal anesthesia with full flexion of spine and immediate extension after local anesthetic administration into the subarachnoid space. Studies have shown that extension of the spine in lateral decubitous position makes cauda equina to sink to the dependent side due to gravity. Continuous flexion of the spine causes sunken cauda equina to be suspended in the middle of the subarachnoid space increasing the possibility of unilateralization of the block. Hence, this study was carried out to assess the effect of flexion and extension in lateral decubitus position in unilateral spinal anesthesia.

Background: Observational studies on pediatric anesthesia neurotoxicity have been unable to distinguish long-term effects of general anesthesia (GA) from factors associated with the need for surgery. A recent study on elementary school children who had received a single GA during the first year of life demonstrated an association in otherwise healthy children between the duration of anesthesia and diminished test scores and also revealed a subgroup of children with "very poor academic achievement" (VPAA), scoring below the fifth percentile on standardized testing. Analysis of postoperative cognitive function in a similar cohort of children anesthetized with an alternative to GA may help to begin to separate the effects of anesthesia from other confounders.. Methods: We used a novel methodology to construct a combined medical and educational database to search for these effects in a similar cohort of children receiving spinal anesthesia (SA) for the same procedures. We compared former patients ...
Introduction: Co-administration of phenylephrine prevents oxytocin-induced hypotension during caesarean section under spinal anaesthesia (SA), but higher doses cause reflex bradycardia. This study compares the effects of co-administration of two different doses of phenylephrine on oxytocin-induced hypotension during caesarean section under SA. Methods: In this prospective, double-blind study, 90 parturients belonging to the American Society of Anesthesiologists physical status 1 or 2, undergoing caesarean section under SA were randomised into Group A: oxytocin 3U and phenylephrine 50 μg, Group B: oxytocin 3U and phenylephrine 75 μg, Group C: oxytocin 3U and normal saline, administered intravenously over 5 min after baby extraction ...
Over the period 2010-2012, maternal mortality linked to anesthesia accounted for 2% of maternal deaths, with no significant change since 2007-2009. Of the 7 maternal deaths analyzed by the expert committee, anesthetic complications were in 5 cases the main cause of death: 4 attributed to direct causes related to anesthetic procedures during childbirth and 1 to indirect cause in connection with an ENT complication during pregnancy. The anesthetic causes of maternal mortality were for the 2010-2012 period: cardiac arrest under spinal anesthesia during caesarean section, local anesthetic intoxication with unsuccessful resuscitation after cardiac arrest without intralipid administration, acute respiratory distress syndrome in the postpartum period after pulmonary aspiration during caesarean section, cardiac arrest during caesarean section under general anesthesia in a context of non-Hodgkin lymphoma with mediastinal syndrome, unsuccessful endotracheal intubation in a context of cellulitis of the ...

METHODS: Women undergoing elective repeat cesarean section with subarachnoid anesthesia (0.5% hyperbaric bupivacaine 8-10 mg and sufentanil 5 μg) were enrolled in a double-blind, randomized study. Patients in the S-Ketamine group (N.=28) received i.v. midazolam 0.02 mg/kg and S-Ketamine 0.5 mg/kg i.m. bolus 10 minutes after birth followed by a 2 μg/kg/min i.v. continuous infusion for 12 h. The control group (N.=28) received placebo. Paracetamol and patient controlled analgesia with intravenous morphine were given postoperatively.

It is not a secret that multiple sexual partners can be followed generally by trichomoniasis. Diagnostics of chlamydia is normally done based on with painful urination. In clinical trials ...
PEARLS Probably the most important factor contributing to success with spinal anesthesia in the day-to-day life of an anesthesiologist is the time efficiency of the technique. Use of spinal anesthesia cannot measurably add to the surgical day if nurses and surgeons are to be co-advocates of this technique. Thus, one should plan ahead to maximize efficiency. Often overlooked in this maxim is the fact that patient preparation for the operation can begin almost as soon as the block is administered if the patient is properly sedated.. Intraoperatively, during high spinal anesthesia (often during cesarean section) patients occasionally complain excessively of dyspnea. This often appears to be a result of loss of chest wall sensation rather than of significantly decreased inspiratory capacity. The loss of chest wall sensation does not allow the patient to experience the reassurance of a deep breath. This impediment to patient acceptance can often be overcome simply by asking the patient to raise a ...

Epidural and Spinal Anesthesia are called "neuraxial anesthesia" and are commonly used for surgery, for pain relief after surgery, and for women in labor.. Epidural - An Epidural is given into your back (outside the spinal cord) by means of a very fine plastic tube, also called a catheter, which is inserted through an epidural needle (the needle is removed after the tubing is in place). Local anesthetic and other pain relieving medications are given through the tubing near the nerves in your back to decrease pain. It works by blocking the pain signals from reaching your brain. The fine plastic tube is taped onto your back and drugs can be given through this fine tube for anywhere from hours to days.. You may have a continuous slow infusion or you may be given a button to push to give yourself a dose of the pain relief medication as you need it. This is called Patient Controlled Epidural Analgesia (PCEA).. Spinal - A spinal anesthetic is performed by administering a single injection of anesthetic ...
Although there are very few investigations into the long-term effects of either type of anaesthesia, low-back pain does appear to be a major complication. A groundbreaking British study by the University of Birmingham (BMJ, 1990; 301: 9-12) showed that nearly 20 per cent of the women given epidurals during labour subsequently went on to suffer persistent low-back pain. A clue to the cause of the problem came from autopsies, where pathologists found non-specific inflammatory reactions in the spine of people who had epidurals. In many cases, there was also evidence of epidural infection (Anaesthesia, 1990; 45: 357-61 ...
