Command-related distribution of regional cerebral blood flow during attempted handgrip. (1/262)

To localize a central nervous feed-forward mechanism involved in cardiovascular regulation during exercise, brain activation patterns were measured in eight subjects by employing positron emission tomography and oxygen-15-labeled water. Scans were performed at rest and during rhythmic handgrip before and after axillary blockade with bupivacaine. After the blockade, handgrip strength was reduced to 25% (range 0-50%) of control values, whereas handgrip-induced heart rate and blood pressure increases were unaffected (13 +/- 3 beats/min and 12 +/- 5 mmHg, respectively; means +/- SE). Before regional anesthesia, handgrip caused increased activation in the contralateral sensory motor area, the supplementary motor area, and the ipsilateral cerebellum. We found no evidence for changes in the activation pattern due to an interaction between handgrip and regional anesthesia. This was true for both the blocked and unblocked arm. It remains unclear whether the activated areas are responsible for the increase in cardiovascular variables, but neural feedback from the contracting muscles was not necessary for the activation in the mentioned areas during rhythmic handgrip.  (+info)

Carotid endarterectomy under regional anesthesia. (2/262)

Regional anesthesia for carotid endarterectomy is a simple, reliable, and virtually complication-free technique. We began to perform a series of carotid endarterectomy under regional anesthesia at our institution in May 1990. This report describes our experience with 180 operated patients from May 1990 till December 1995, with regional anesthesia. All patients were operated with microsurgery and we utilized the deeply cervical plexus block at the C-4 level associated with superficial block, along the posterior border of the externocleidomastoid muscle. The main advantage of this technique of anesthesia is that it is the only exact method of assessing the need of a shunt by using the neurological status of the awaken patient during trial carotid cross-clamping. The regional anesthesia allows carotid endarterectomy to be safely performed on patients with advanced cardiac disease or severe chronic obstructive pulmonary disease who were not good candidates for general anesthesia. In this 180 patients we performed 198 consecutive endarterectomies (10% bilateral) with a total morbidity-mortality rate of 2.0%.  (+info)

Intravenous regional anesthesia (Bier block) in a dog. (3/262)

Effects of general and locoregional anesthesia on reproductive outcome for in vitro fertilization: a meta-analysis. (4/262)

The objective of this meta-analysis was to evaluate prospective trials of general or locoregional anesthesia on reproductive outcomes (cleavage and pregnancy rate) for in vitro fertilization (IVF). Of 115 published studies retrieved from a search of articles indexed on MEDLINE from 1966 to February 1999, four studies with distinct general and locoregional anesthesia were deemed eligible for meta- analysis. The pooled relative risk and odds ratios were calculated. A test for homogeneity was also performed. The pooled log odds ratio was 1.03 (95% CI 0.90-1.18) in cleavage rate and 0.71 (95% CI 0.47-1.08) in pregnancy rate. Heterogeneity was negative. Cleavage and pregnancy rates were not significantly different in both the general anesthesia and locoregional anesthesia groups. Both anesthetic techniques were favorable to IVF procedure by available published evidence when anesthesia was needed.  (+info)

Severe vasovagal attack during regional anaesthesia for caesarean section. (5/262)

A patient experienced a severe vasovagal attack during regional anaesthesia for elective Caesarean section.

The effect of anesthetic technique on postoperative outcomes in hip fracture repair. (6/262)

BACKGROUND: The impact of anesthetic choice on postoperative mortality and morbidity has not been determined with certainty. METHODS: The authors evaluated the effect of type of anesthesia on postoperative mortality and morbidity in a retrospective cohort study of consecutive hip fracture patients, aged 60 yr or older, who underwent surgical repair at 20 US hospitals between 1983 and 1993. The primary outcome was defined as death within 30 days of the operative procedure. The secondary outcomes were postoperative 7-day mortality, postoperative myocardial infarction, postoperative pneumonia, postoperative congestive heart failure, and postoperative change in mental status. Numerous comorbid conditions were controlled for individually and by several comorbidity indices using logistic regression. RESULTS: General anesthesia was used in 6,206 patients (65.8%) and regional anesthesia in 3,219 patients (3,078 spinal anesthesia and 141 epidural anesthesia). The 30-day mortality rate in the general anesthesia group was 4.4%, compared with 5.4% in the regional anesthesia group (unadjusted odds ratio = 0.80; 95% confidence interval = 0.66-0.97). However, the adjusted odds ratio for general anesthesia increased to 1.08 (0.84-1.38). The adjusted odds ratios for general anesthesia versus regional anesthesia for the 7-day mortality was 0.90 (0.59-1.39) and for postoperative morbidity outcomes were as follows: myocardial infarction: adjusted odds ratio = 1.17 (0.80-1.70); congestive heart failure: adjusted odds ratio = 1.04 (0.80-1.36); pneumonia: adjusted odds ratio = 1.21 (0.87-1.68); postoperative change in mental status: adjusted odds ratio = 1.08 (0.95-1.22). CONCLUSIONS: The authors were unable to demonstrate that regional anesthesia was associated with better outcome than was general anesthesia in this large observational study of elderly patients with hip fracture. These results suggest that the type of anesthesia used should depend on factors other than any associated risks of mortality or morbidity.  (+info)

Ophthalmic regional anesthesia: medial canthus episcleral (sub-tenon) anesthesia is more efficient than peribulbar anesthesia: A double-blind randomized study. (7/262)

BACKGROUND: Regional anesthesia and especially peribulbar anesthesia commonly is used for cataract surgery. Failure rates and need for reinjection remains high, however, with peribulbar anesthesia. Single-injection high-volume medial canthus episcleral (sub-Tenon's) anesthesia has proven to be an efficient and safe alternative to peribulbar anesthesia. METHODS: The authors, in a blind study, compared the effectiveness of both techniques in 66 patients randomly assigned to episcleral anesthesia or single-injection peribulbar anesthesia. Motor blockade (akinesia) was used as the main index of anesthesia effectiveness. It was assessed using an 18-point scale (0-3 for each of the four directions of the gaze, lid opening, and lid closing, the total being from 0 = normal mobility to 18 = no movement at all). This score was compared between the groups 1, 5, 10, and 15 min after injection and at the end of the surgical procedures. Time to onset of the blockade also was compared between the two groups, as was the incidence of incomplete blockade with a need for supplemental injection and the satisfaction of the surgeon, patient, and anesthesiologist. RESULTS: Episcleral anesthesia provided a quicker onset of anesthesia, a better akinesia score, and a lower rate of incomplete blockade necessitating reinjection (0 vs. 39%; P < 0.0001) than peribulbar anesthesia. Even after supplemental injection, peribulbar anesthesia had a lower akinesia score than did episcleral anesthesia. Peribulbar anesthesia began to wear off during surgery, whereas episcleral anesthesia did not. CONCLUSION: Medial canthus single-injection episcleral anesthesia is a suitable alternative to peribulbar anesthesia. It provides better akinesia, with a quicker onset and more constancy in effectiveness.  (+info)

General versus regional anaesthesia for hip fracture surgery: a meta-analysis of randomized trials. (8/262)

Hip fracture surgery is common and the population at risk is generally elderly. There is no consensus of opinion regarding the safest form of anaesthesia for these patients. We performed a meta-analysis of 15 randomized trials that compare morbidity and mortality associated with general or regional anaesthesia for hip fracture patients. There was a reduced 1-month mortality and incidence of deep vein thrombosis in the regional anaesthesia group. Operations performed under general anaesthesia had a reduction in operation time. No other outcome measures reached a statistically significant difference. There was a tendency towards a lower incidence of myocardial infarction, confusion and postoperative hypoxia in the regional anaesthetic group, and cerebrovascular accident and intra-operative hypotension in the general anaesthetic group. We conclude that there are marginal advantages for regional anaesthesia compared to general anaesthesia for hip fracture patients in terms of early mortality and risk of deep vein thrombosis.  (+info)

Routine use of regional anesthesia for patients having surgery is supported by general safety and proven effectiveness as a targeted modality in the prevention and treatment of acute pain. Recently, perioperative physicians have become much more interested in improving long-term outcomes after surgery rather than focusing on the well-established short-term benefits of regional anesthesia. This interest has raised important questions regarding the potential influence of regional anesthesia on morbidity and mortality, persistent pain and cancer prognosis. Tissue injury is responsible for the inflammatory reaction and physiologic stress response observed during the perioperative period and can influence a patients recovery trajectory. Regional anesthesia can modulate the inflammatory response through the direct anti-inflammatory effect of local anesthetics, blocking neural afferents, and blunting sympathetic activation. Moreover, continuous techniques (e.g., epidural and perineural catheters) that ...
Ultrasound has revolutionized the practice of regional anesthesia, yet there remains a paucity of good resources on ultrasound-guided regional anesthesia in children. This book offers a much-needed practical guide to all the major ultrasound-guided blocks in pediatric patients, including neuraxial, truncal, upper and lower limb blocks. The core principles of good clinical practice in regional anesthesia are described and discussed, including the pharmacology of local anesthetics in children, the performance of regional anesthesia, the management of complications, and the clinical anatomy of each block. Every block chapter provides both a how to section and also a comprehensive literature review, with an up-to-date and relevant bibliography for reference and further reading. Chapters are illustrated with unique anatomical images and detailed descriptions. Both trainee and experienced anesthesiologists will find this an essential resource for the safe and effective performance of modern regional ...
Nerve blocks and regional anesthesia are commonly used to manage acutely painful conditions. These procedures are becoming commonplace in order to limit the use of opioid medications. Single-shot blocks using long acting anesthetics provide significant pain relief for patients. Continuous regional anesthesia using extended stay catheters and infusion pumps may offer ongoing pain control for up to 7 days. Applications for regional anesthesia are ever expanding, but it is challenging for busy clinicians to confidently learn these practical skills.. Topics covered in the Regional Anesthesia for Acute Care Providers course and lab sessions include:. ...

The advent of ultrasound guidance has led to a renewed interest in regional anesthesia of the lower limb. In keeping with the American Society of Regional Anesthesia and Pain Medicines ongoing commitment to provide intensive evidence-based education, this article presents a complete update of the 2005 comprehensive review on lower extremity peripheral nerve blocks. The current review article strives to (1) summarize the pertinent anatomy of the lumbar and sacral plexuses, (2) discuss the optimal approaches and techniques for lower limb regional anesthesia, (3) present evidence to guide the selection of pharmacological agents and adjuvants, (4) describe potential complications associated with lower extremity nerve blocks, and (5) identify informational gaps pertaining to outcomes, which warrant further investigation.
Neurologic complications as an adverse effect occur in all types of regional anesthesia. Reviewing the literature, the incidence spreads from 0.02 up to 3 percent. The incidence remains unclear because of different types of definitions, too. In this study, we evaluate all patients receiving peripheral regional anesthesia 24 hours after block performance according to a standardized study protocol. In case of any conspicuousness concerning motoric or sensory function or pain, the patient will be evaluated again after 48 hours. Further on, in case of neurologic dysfunction, periods of investigation will be after 3 days, 1 week, 2 weeks, 1 month, 3 months, 6 months and 1 year. This study includes the definition for nerve damage concerning motoric and sensory neural function and pain.. The patients will be recruited among all patients from our hospital receiving continuous peripheral regional anesthesia. ...

Background: There is consistent and significant variation in neuraxial anesthesia use for hip fracture surgery across jurisdictions. We measured the association of hospital-level utilization of neuraxial anesthesia, independent of patient-level use, with 30-day survival (primary outcome) and length of stay and costs (secondary outcomes). Methods: We conducted a population-based cohort study using linked administrative data in Ontario, Canada. We identified all hip fracture patients more than 65 yr of age from 2002 to 2014. For each patient, we measured the proportion of hip fracture patients at their hospital who received neuraxial anesthesia in the year before their surgery. Multilevel, multivariable regression was used to measure the association of log-transformed hospital-level neuraxial anesthetic-use proportion with outcomes, controlling for patient-level anesthesia type and confounders. Results: Of 107,317 patients, 57,080 (53.2%) had a neuraxial anesthetic; utilization varied from 0 to ...

Providing competent regional anesthesia care entails not just technical proficiency in performing blocks but also skills in clinical decision making, working on a team, and quality improvement.[5-7] Those nontechnical skills can be more difficult to teach and assess than technical proficiency yet are critical components of competency in regional anesthesia. Focusing regional anesthesia education on a small number of proven blocks and their associated safety and clinical decision pathways allows residents to learn both the technical and nontechnical aspects of those blocks. Developing critical decision-making skills for selected blocks in residency can serve as a template for future decision making in regional anesthesia and will prepare residents to incorporate yet-to-be described regional anesthesia techniques into their clinical practice following completion of their residency training.. The number of regional anesthesia techniques taught to ensure competence during residency may vary between ...
The single most common block (40 percent) was a single-injection block in the pelvic area (caudal block) for procedures in the lower body (for example, hernia surgery). However, blocks of the peripheral nerves were common as well (35 percent), especially for surgery on the upper and lower limbs.. The large numbers of single-injection peripheral nerve blocks seemed related to increased use of ultrasound to guide local anesthetic injections. Ultrasound was used in more than 80 percent of upper-limb blocks and nearly 70 percent of lower-limb blocks.. As the use of regional anesthesia continues to increase, there is a lack of detailed and complete information on its safety in children. The best available studies, performed in Europe, are more than a decade old. Thus they may not reflect modern practice, including the use of ultrasound guidance.. Because complications of regional anesthesia are relatively uncommon, very large databases are needed to provide meaningful estimates of the true risks. ...

Today, the crisis of drug shortages threatens to reverse the many advances in perioperative pain control that have been achieved. Local anesthetics or numbing medications represent a class of drugs that is our strongest weapon against opioids. These drugs (e.g., bupivacaine, lidocaine, ropivacaine) are currently in shortage. Targeted injections of local anesthetic in the form of regional anesthesia eliminate sensation at the site of surgery and can obviate the need for injectable opioids (e.g., fentanyl, hydromorphone, morphine) which also happen to be in short supply. Local anesthetics are also the critical ingredient in providing epidural pain relief and spinal anesthesia for childbirth. Without them, new moms will miss the first moments of their babies lives.. The following are potential ramifications of the current drug shortages affecting anesthesia and pain management on patient care:. Decreased Quality of Acute Pain Management. Regional anesthesia techniques, which include spinal, ...

1) Loss of feeling or awareness. A general anesthetic puts the person to sleep. A local anesthetic causes loss of feeling in a part of the body such as a tooth or an area of skin without affecting consciousness. Regional anesthesia numbs a larger part of the body such as a leg or arm, also without affecting consciousness. The term conduction anesthesia encompasses both local and regional anesthetic techniques. Many surgical procedures can be done with conduction anesthesia without significant pain. In many situations, such as a C-section, conduction anesthesia is safer and therefore preferable to general anesthesia. However, there are also many types of surgery in which general anesthesia is clearly appropriate.

Ultrasound Guided Regional Anesthesia - Ultrasound technology is enabling anesthesiologists to perform regional anesthetic procedures with greater confidence (EAN:9780190231811)
WEDNESDAY, June 17, 2020 (HealthDay News) -- Anesthesiologists can help save the planet, a new study suggests.. Increased use of regional anesthesia instead of general anesthesia may help reduce greenhouse gas emissions that contribute to climate change, according to researchers at the Hospital for Special Surgery in New York City.. Unlike general anesthesia, regional anesthesia doesnt use volatile halogenated agents, such as desflurane, or nitrous oxide. These are greenhouse gases that can remain in the atmosphere for up to 114 years, the researchers noted.. Instead of those gases, regional anesthesia uses a local nerve block along with intravenous sedatives.. Increasing the use of regional anesthesia is potentially good for the climate, improves the quality of care (at least for hip and knee replacements), and may allow individual practitioners to take personal responsibility in the fight against global warming, said Dr. Christopher Wu, an anesthesiologist at the hospital, and ...
A patient is on anticoagulant therapy for a prosthetic mitral valve, and is scheduled for surgery. Should she receive regional anesthesia?. Regional anesthesia is possible if it is clearly indicated. Since the risk of thrombosis or embolism is increased without anticoagulation, and if general anesthesia carries more risk in this setting, timing can be co-ordinated so that minimal risk of thrombosis and neuraxial bleeding occur.. 2. How does one manage the dis-continuation of oral anticoagulant therapy?. Discontinue oral therapy three to five days prior to surgery, and begin intravenous heparin also. Stop heparin four to six hours prior to regional anesthesia, and restart after one hour if needed. If surgical bleeding is to be significant, restart after twelve or more hours.. 3. Can regional anesthesia be performed on a patient taking aspirin for osteoarthritis?. Yes, if there is no history of bleeding or bruising, spinal or epidural anesthesia is appropriate ...

Regional Anesthesia (RA) and peripheral nerve blocks (PNBs) improve patient outcomes. RA and multimodal analgesia have revolutionized pain management to reduce dependency on opioids and gas anesthesia.
TUESDAY, June 24, 2014 (HealthDay News) -- Hip fracture surgery patients who are given regional anesthesia have a slightly lower risk of death and a slightly shorter hospital stay than those who receive general anesthesia, a new study shows. Regional anesthesia involves delivery of anesthesia directly to the affected part of the body without putting the patient to sleep.
Microorganisms from exogenous or endogenous sources may gain access to the subarachnoid, epidural, or tissue space surrounding peripheral nerves in several ways. Microorganisms from the patients or anesthesia practitioners flora can be inoculated directly when a catheter or needle is inserted into those spaces. Several reports in the literature suggest that infections are on occasion caused by the anesthesia practitioners flora.1-3 For example, Trautmann and colleagues reported a case of meningitis caused by a Staphylococcus aureus strain that was identical by pulsed-field gel electrophoresis to the S. aureus isolate from the anesthesiologists nose.2 Microorganisms can also enter the epidural space by hematogenous spread from other body sites, such as infected skin,2,4 or by migrating along the catheter tract.5,6 Several case reports suggested that infection was caused by spread of bacteria from infected sites through the bloodstream to the epidural space.7-9 Others maintain that infections ...

Intravenous regional anesthesia (IVRA) or Bier block anesthesia is an anesthetic technique for surgical procedures on the bodys extremities where a local anesthetic is injected intravenously. The technique usually involves exsanguination, which forces blood out of the extremity, followed by the application of pneumatic tourniquets to safely stop blood flow. The anesthetic agent is introduced into the limb and allowed to set in while tourniquets retain the agent within the desired area. The use of tourniquets and injected agents to induce localized anesthesia was first introduced by August Bier in 1908. He used an Esmarch bandage to exsanguinate the arm and injected procaine between two tourniquets to quickly produce anesthetic and analgesic effects in the site. Though it proved effective, IVRA remained relatively unpopular until C. McK. Holmes reintroduced it in 1963. Today, the technique is common due to its economy, rapid recovery, reliability, and simplicity. Protocols vary depending on ...

These head movements add time and complexity to the procedure. The head-mounted display (HMD) device is a commercially available head-mounted video display that is connected to the ultrasound machine and projects the ultrasound image onto the HMD glasses, enabling the anesthesiologist to monitor the screen without ever needing to look away from the patient. We hypothesized that the use of the HMD device would decrease the total procedure time as well as operator head and ultrasound probe movements during ...
Regional anesthesia is a growing frontier in modern clinical anesthesia, in part because of the availability of ultrasonic imaging to help us direct needle placement. The subspecialty of regional anesthesia has blossomed. Listening to some of its disciples, it would seem that nearly every orthopedic surgery procedure can benefit from an ultrasonic regional block for intraoperative and postoperative pain control.. Anesthesiology News (Hardman D, July 2015, 41:7) recently reviewed the topic of nerve injury after peripheral nerve block. Data shows that the risk for permanent or severe nerve injury after peripheral nerve blocks is low. Per the article, the prevalence of permanent injury rates as defined by a neurologic abnormality present at or beyond 12 months after the procedure, ranges from 0.029% to 0.2%.. Low, but not zero.. There is a high incidence of temporary postoperative neurologic symptoms after arthroscopic shoulder surgery, whether the patient received a regional block or not. The ...

Protocols vary depending on local standard procedures and the extremity being operated on. A vast majority of practitioners begin by exsanguinating the limb as Bier did with an elastic bandage (Esmarch bandage), squeezing blood proximally toward the heart, then pneumatic tourniquets are applied to the limb and inflated 30mmHg above arterial pressure to occlude all blood vessels and then the elastic bandage is removed. A high dose of local anesthetic, typically lidocaine or prilocaine without adrenaline,[6] is slowly injected as distally as possible into the exsanguinated limb. The veins are filled with the anesthetic, with the anesthetic setting into local tissue after approximately 6-8 minutes, after which the surgery, reduction, or manipulation of the region may begin. It is important that the region is isolated from active blood flow at this time. Analgesic effect typically remains for up to two hours depending on the dosage and type of anesthetic agent being used. The wait time and isolation ...

Local anesthesia is any technique to induce the absence of sensation in a specific part of the body, generally for the aim of inducing local analgesia, that is, local insensitivity to pain, although other local senses may be affected as well. It allows patients to undergo surgical and dental procedures with reduced pain and distress. In many situations, such as cesarean section, it is safer and therefore superior to general anesthesia. It is also used for relief of non-surgical pain and to enable diagnosis of the cause of some chronic pain conditions. Anesthetists sometimes combine both general and local anesthesia techniques. The following terms are often used interchangeably: Local anesthesia, in a strict sense, is anesthesia of a small part of the body such as a tooth or an area of skin. Regional anesthesia is aimed at anesthetizing a larger part of the body such as a leg or arm. Conduction anesthesia encompasses a great variety of local and regional anesthetic techniques. A local anesthetic ...

Regional Anesthesia Regional anesthesia involves numbing a specific area of the body, without affecting your brain or breathing. Because you remain conscious, you will be given sedatives to relax you and put you in a light sleep.The two types of regional anesthesia used most frequently in joint replacement surgery are spinal blocks and epidural blocks. For surgery below the hip, a combination block that targets the lumbar plexus and the sciatic nerve can numb only one leg.Spinal BlockIn a spinal block, the anesthesia is injected into the fluid surrounding the spinal cord in the lower part of your back. This produces a rapid numbing effect that can last for hours, depending on the drug used.Epidural BlockAn epidural block uses a small tube (catheter) inserted in your lower back to deliver large quantities of local anesthetics over a longer time period. The epidural block and the spinal block are administered in a very similar location; however, the epidural catheter is placed slightly closer to ...
Regional anaesthesia is often preferred in ankle fracture surgery due to the superior safety profile and probably better postoperative pain control compared with general anaesthesia.17 19 33 To the best of our knowledge, AnAnkle Trial is the first study to thoroughly investigate the postoperative pain profile and test which one of the most frequently used regional anaesthesia techniques is superior. Postoperative pain studies are often limited by large time intervals between pain registrations. We designed our trial to avoid this issue since it renders evaluation of the clinical significance of rebound pain impossible, because the rebound could be very intense yet completely undetected in-between pain scorings.. AnAnkle Trial constitutes a scientifically strong set-up, although blinding of the participants and investigators is not practically possible, which holds a potential risk of bias; for example, reported pain scores might be affected by psychological factors influenced by information from ...
|p|Anesthesia is the use of medication to relieve or eliminate pain during a medical procedure. The medication, called an anesthetic, is usually given by a specialist known as an anesthesiologist, though it sometimes given by another health care provider. Anesthesia can be given for procedures in a doctors office, a hospital, a medical center or an ambulatory surgical center. |/p||p||b| Types of Anesthesia|/b||/p||p|There are several types of anesthesia, and the type a doctor decides to use will vary based on the nature and seriousness of the medical procedure. Local anesthesia is the least extensive kind of anesthesia, and it is used to numb just one part of the body, usually via an injection. For surgery on the foot or hand, for example, local anesthesia may be used. Regional anesthesia is similar but more extensive, and its used to numb an entire region of the body. An epidural given to a woman during childbirth is a type of regional anesthesia.|/p||p|The most extensive form of anesthesia is known
Why this is important:- No recent randomised controlled trials were identified that fully address this question. The evidence is old and does not reflect current practice. In addition, in most of the studies the patients are sedated before regional anaesthesia is administered, and this is not taken into account when analysing the results. The study design for the proposed research would be best addressed by a randomised controlled trial. This would ideally be a multi-centre trial including 3000 participants in each arm. This is achievable given that there are about 70,000 to 75,000 hip fractures a year in the UK. The study should have three arms that look at spinal anaesthesia versus spinal anaesthesia plus sedation versus general anaesthesia; this would separate those with regional anaesthesia from those with regional anaesthesia plus sedation. The study would also need to control for surgery, especially type of fracture, prosthesis and grade of surgeon ...

Anesthesiologists are the physicians trained to administer anesthetics, which are drugs designed to produced anesthesia (an insensibility to pain). Anesthetics can be administered on patients before, during, or after surgery. There are three general categories of anesthesia: 1) General anesthesia is affects a persons entire state of consciousness, 2) Regional anesthesia affects a region of the body, and 3) Local anesthesia works like regional anesthesia, but it affects an even smaller area of the body. See below to locate an anesthesiologist in Greenville, NC.

Way back in 2003-2004, when I started practicing anesthesia, I thought that relationship with surgeons and hospital is the key factor in my branch. In addition, I wanted to avoid any interaction with the public; therefore, I had joined the field of anesthesia. However, more than a decade later, my impression about the field has undergone a sea change and today it is completely the opposite! Communication/discussion with patients and public is the key factor for me. I prepare, communicate, and decide remuneration for my work. The journey from 2006 to 2017 has been rather tough and full of challenges! Moreover, it is also that phase of my career where I have learnt the most. Today I enjoy anesthesia, my remuneration, recognition, and company with my friends, family, and public.
Meperidine is a synthetic opiate agonist belonging to the phenylpiperidine class. Meperidine may produce less smooth muscle spasm, constipation, and depression of the cough reflex than equivalent doses of morphine. The onset of action is lightly more rapid than with morphine, and the duration of action is slightly shorter. The chemical structure of meperidine is similar to local anesthetics. Meperidine is recommended for relief of moderate to severe acute pain and has the unique ability to interrupt postoperative shivering and shaking chills induced by amphotericin B. Meperidine has also been used for intravenous regional anesthesia, peripheral nerve blocks and intraarticular, epidural and spinal analgesia. Meperidine is considered a second-line agent for the treatment of acute pain ...
