Adult circumcision. (1/1198)

Adult circumcision can be performed under local or regional anesthesia. Medical indications for this procedure include phimosis, paraphimosis, recurrent balanitis and posthitis (inflammation of the prepuce). Nonmedical reasons may be social, cultural, personal or religious. The procedure is commonly performed using either the dorsal slit or the sleeve technique. The dorsal slit is especially useful in patients who have phimosis. The sleeve technique may provide better control of bleeding in patients with large subcutaneous veins. A dorsal penile nerve block, with or without a circumferential penile block, provides adequate anesthesia. Informed consent must be obtained. Possible complications of adult circumcision include infection, bleeding, poor cosmetic results and a change in sensation during intercourse.  (+info)

Ropivacaine or 2% mepivacaine for lower limb peripheral nerve blocks. Study Group on Orthopedic Anesthesia of the Italian Society of Anesthesia, Analgesia, and Intensive Care. (2/1198)

BACKGROUND: Intra- and postoperative clinical properties of sciatic-femoral nerve block performed with either ropivacaine at different concentrations or mepivacaine have been evaluated in a multicenter, randomized, blinded study. METHODS: Adult patients scheduled for foot and ankle surgery were randomized to receive combined sciatic-femoral nerve block with 225 mg of either 0.5% (n = 83), 0.75% (n = 87), or 1% (n = 86) ropivacaine, or with 500 mg of 2% mepivacaine (n = 84). A thigh tourniquet was used in all patients. Onset time, adequacy of surgical anesthesia, time to offset of nerve block, and time until first postoperative requirement for pain medication were evaluated by a blinded observer. RESULTS: The adequacy of nerve block was similar in the four treatment groups (the ratios between adequate:inadequate: failed blocks were 74:9:0 with 0.5% ropivacaine, 74:13:0 with 0.75% ropivacaine, 78:8:0 with 1% ropivacaine, and 72:12:0 with 2% mepivacaine). The onset of the block was slower with 0.5% ropivacaine than with other anesthetic solutions (P < 0.001). Regardless of the concentration, ropivacaine produced a longer motor blockade (10.5+/-3.8 h, 10.3+/-4.3 h, and 10.2+/-5.1 h with 0.5%, 0.75%, and 1% ropivacaine, respectively) than with mepivacaine (4.3+/-2.6 h; P < 0.001). The duration of postoperative analgesia was shorter after mepivacaine (5.1+/-2.7 h) than after ropivacaine (12.2+/-4.1 h, 14.3+/-5 h, and 14.5+/-3.4 h, with 0.5%, 0.75%, or 1% ropivacaine, respectively; P < 0.001). Pain relief after 0.5% ropivacaine was 14% shorter than 0.75% or 1% ropivacaine (P < 0.05). During the first 24 h after surgery, 30-37% of patients receiving ropivacaine required no analgesics compared with 10% of those receiving mepivacaine (P < 0.001). CONCLUSIONS: This study suggests that 0.75% ropivacaine is the most suitable choice of local anesthetic for combined sciatic-femoral nerve block, providing an onset similar to mepivacaine and prolonged postoperative analgesia.  (+info)

Clinically safe dosage of felypressin for patients with essential hypertension. (3/1198)

Hemodynamic changes were evaluated in patients with essential hypertension when felypressin of various concentrations was administered. The parameters studied were systolic pressure, diastolic pressure, heart rate, left ventricular systolic phase, and endocardial viability ratio. Results showed that blood pressure tended to increase, and the value of 1/pre-ejection period2 (PEP2) tended to decrease, upon administration of 3 ml of 2% propitocaine containing 0.06 international units/ml (IU/ml) of felypressin. Significant increase of blood pressure and decrease in 1/PEP2 was noted upon administration of 3 ml of anesthetic solution containing 0.13 IU/ml of felypressin. No ischemic change of the myocardium was detected even with the highest felypressin concentration (3 ml of 2% propitocaine containing 0.25 IU/ml of felypressin). These results suggest that the clinically safe dosage of felypressin for patients with essential hypertension is approximately 0.18 IU. This amount is equivalent to 6 ml of 3% propitocaine with 0.03 IU/ml of felypressin, which is a commercially available local anesthetic for dental use. It seems that the decrease in 1/PEP2 that occurred during blood pressure increase was due to the increase in afterload caused by contraction of the arterioles. Although in the present study no ischemic change was noted, special care should be taken to prevent myocardial ischemia in patients with severe hypertension.  (+info)

Prolonged diplopia following a mandibular block injection. (4/1198)

A case is presented in which a 14-yr-old girl developed diplopia after injection of the local anesthetic Xylotox E 80 A (2% lidocaine with 1:80,000 epinephrine). Since the complication had a relatively slow onset and lasted for 24 hr, the commonly suggested explanations based on vascular, lymphatic, and neural route theories do not adequately fit the observations. No treatment, other than reassurance, was necessary, and the patient recovered fully.  (+info)

Efficacy of mandibular topical anesthesia varies with the site of administration. (5/1198)

This study compared the threshold of pain sensitivity in the anterior mandibular mucobuccal fold with the posterior. This was followed by a comparison of the reduction of needle insertion pain in the anterior mucobuccal fold and the pterygo-temporal depression by either topical anesthesia or nitrous oxide inhalation. The pain threshold was determined by an analgometer, a pain-measuring device that depends on pressure readings; additionally, pain caused by a needle inserted by a normal technique was assessed using a visual analog scale (VAS). The threshold of pain was significantly lower in the incisor and canine regions than in the premolar and the molar regions (P < 0.001). Compared to a placebo, topical anesthesia significantly reduced the pain from needle insertion in the mucobuccal fold adjacent to the mandibular canine (P < 0.001), but did not significantly reduce pain in the pterygotemporal depression. The addition of 30% nitrous oxide did not significantly alter pain reduction compared to a control of 100% oxygen. These results suggest that topical anesthesia application may be effective in reducing the pain of needle insertion in the anterior mandibular mucobuccal fold, but may not be as effective for a standard inferior alveolar nerve block. The addition of 30% nitrous oxide did not lead to a significant improvement.  (+info)

Anti-ganglioside antibodies can bind peripheral nerve nodes of Ranvier and activate the complement cascade without inducing acute conduction block in vitro. (6/1198)

The neurophysiological effects of nine neuropathy-associated human anti-ganglioside antisera, three monoclonal antibodies to ganglioside GM1 (GM1) and of the cholera toxin B subunit (a GM1 ligand) were studied on mouse sciatic nerve in vitro. GM1 antisera and monoclonal antibodies from patients with chronic motor neuropathies and Guillain-Barre syndrome, and GQ1b/ disialosyl antisera and monoclonal antibodies from patients with chronic ataxic neuropathies and Miller Fisher syndrome were studied. In vitro recording, for up to 6 h, of compound nerve action potentials, latencies, rise times and stimulus thresholds from isolated desheathed sciatic nerve was performed in the presence of antiganglioside antibodies and fresh human serum as an additional source of complement. No changes were observed over this time course, with 4-6 h values for all electrophysiological parameters being within 15% of the starting values for both normal and antibody containing sera and for the cholera toxin B subunit. Parallel experiments on identically prepared desheathed nerves performed with 0.5 nM saxitoxin led to complete conduction block within 10 min of application. Under identical conditions to those used for electrophysiological recordings, quantitative immunohistological evaluation revealed a significant increase in IgM (immunoglobulin M) deposition at nodes of Ranvier from 5.3+/-3.1% to 28.7+/-8.4% (mean+/-SEM) of desheathed nerves exposed to three normal and three antibody containing sera, respectively (P < 0.03). Complement activation was seen at 100% of normal and 79% of disease-associated IgM positive nodes of Ranvier. These data indicate that anti-ganglioside antibodies can diffuse into a desheathed nerve, bind to nodes of Ranvier and fix complement in vitro without resulting in any overt physiological deterioration of the nerve over 4-6 h. This suggests that the node of Ranvier is relatively resistant to acute antiganglioside antibody mediated injury over this time scale and that anti-ganglioside antibodies and the cholera toxin B subunit are unlikely to have major direct pharmacological effects on nodal function, at least in comparison with the effect of saxitoxin. This in vitro sciatic nerve model appears of limited use for analysing electrophysiologically the effects of anti-ganglioside antibodies on nerve function, possibly because its short-term viability and isolation from circulating systemic factors do not permit the evolution of an inflammatory lesion of sufficient magnitude to induce overt electrophysiological abnormalities. In vivo models may be more suitable for identifying the effects of these antibodies on nerve conduction.  (+info)

Conduction block in carpal tunnel syndrome. (7/1198)

Wrist extension was performed in six healthy subjects to establish, first, whether it would be sufficient to produce conduction block and, secondly, whether the excitability changes associated with this manoeuvre are similar to those produced by focal nerve compression. During maintained wrist extension to 90 degrees, all subjects developed conduction block in cutaneous afferents distal to the wrist, with a marked reduction in amplitude of the maximal potential by >50%. This was associated with changes in axonal excitability at the wrist: a prolongation in latency, a decrease in supernormality and an increase in refractoriness. These changes indicate axonal depolarization. Similar studies were then performed in seven patients with carpal tunnel syndrome. The patients developed conduction block, again with evidence of axonal depolarization prior to block. Mild paraesthesiae were reported by all subjects (normals and patients) during wrist extension, and more intense paraesthesiae were reported following the release of wrist extension. In separate experiments, conduction block was produced by ischaemic compression, but its development could not be altered by hyperpolarizing currents. It is concluded that wrist extension produces a 'depolarization' block in both normal subjects and patients with carpal tunnel syndrome, much as occurs with ischaemic compression, but that this block cannot be altered merely by compensating for the axonal depolarization. It is argued that conduction slowing need not always be attributed to disturbed myelination, and that ischaemic compression may be sufficient to explain some of the intermittent symptoms and electrodiagnostic findings in patients with carpal tunnel syndrome, particularly when it is of mild or moderate severity.  (+info)

Respiratory effects of low-dose bupivacaine interscalene block. (8/1198)

In this double-blind study, interscalene brachial plexus (ISBP) block was performed in 11 volunteers using 10 ml of either 0.25% (n = 6) or 0.5% (n = 5) bupivacaine with epinephrine 1:200,000. Diaphragmatic excursion, respiratory function and neural function were assessed for 90 min. Our results showed that hemidiaphragmatic excursion declined significantly after block in the 0.5% group and paradoxical movement during inspiration was more common than in the 0.25% group. Forced vital capacity and forced expiratory volume in 1 s declined significantly in the 0.5% group (mean 74.6 (SD 13.0)% and 78.2 (19.9)% of baseline, respectively) but not in the 0.25% group. Sensory anaesthesia in the upper limb was found consistently in both groups, although biceps paralysis occurred earlier after 0.5% bupivacaine. We conclude that ISBP block using 10 ml of 0.25% bupivacaine provided upper limb anaesthesia to pinprick in C5-6 dermatomes with only occasional interference with respiratory function.  (+info)

A peripheral nerve block is an anesthetic practice used in many surgical procedures. It is accomplished by injecting a local anesthetic near the nerve controlling sensation or movement to the area of the body requiring surgery. Peripheral nerve blocks are an alternative to general anesthesia and central nerve blocks for surgery.. There are several advantages to peripheral nerve blocks, including reduced risk of post-operative fatigue and vomiting as well as improved post-operative pain management. Patients often require less pain medication during recovery when a peripheral nerve block was used in surgery. Because a peripheral nerve block only affects the area of the body being operated on, patients have an option to be awake or asleep during the procedure.. What Happens during Peripheral Nerve Blocks?. Prior to administering the peripheral nerve block, the patient will receive an IV in the hand or arm to dispense intravenous pain medicine. This allows the body to relax as it prepares for the ...
Over 40% of ambulatory patients experience moderate-to-severe postoperative pain at home following orthopedic procedures.1 Single-injection peripheral nerve blocks with long-acting local anesthetics can provide excellent postoperative analgesia. However, the analgesic benefit of single-injection blocks is typically limited to the duration of the blockade and, subsequently, patients must usually rely on oral opioids to control pain. Unfortunately, opioids are associated with undesirable side effects, such as pruritus, nausea and vomiting, sedation, and constipation. To improve postoperative analgesia following ambulatory surgery, increasing interest has focused on providing perineural local anesthetic infusions, also called, continuous peripheral nerve blocks, to outpatients. This technique involves a percutaneous insertion of a catheter directly adjacent to the peripheral nerve(s) supplying the surgical site ...
What is a selective nerve root block?. In a lumbar epidural injection, a corticosteroid (anti-inflammatory medicine) is injected into the epidural space to reduce inflammation. A local anesthetic n(numbing medicine) may also be injected. If the needle is positioned next to an individual nerve root, it is called a selective nerve root block. This technique puts medication directly along an inflamed nerve root.. What happens during an injection?. A local anesthetic will be used to numb your skin. The doctor will then insert a thin needle directly into the epidural space. Fluoroscopy, a type of x-ray, must be used to ensure the safe and proper position of the needle. A dye may also be injected to make sure the needle is at the correct spot.. Once the doctor is sure the needle is correctly placed, the medicine will be injected.. What happens after an injection?. You will be monitored for up to 30 minutes after the injection. When you are ready to leave, the staff will give you discharge ...

However, compared with neuraxial and general anesthesia, success with peripheral nerve blocks is undoubtedly more anesthesiologist-dependent.14-16 Technical skills and determination are required for the successful implementation of peripheral nerve blocks. Factors such as accurate identification of surface landmarks and an adequate number of supervised, successful attempts at each block are necessary for safe, effective peripheral nerve block implementation.14,16-18 A dedicated team of well-trained anesthesiologists is a prerequisite to ensure consistent peripheral nerve block service in any institution.19,20 Intraoperative management, once the block has been placed, requires diligent observation and judicious use of supplemental drugs for anxiolysis and sedation. Postoperative management, including patient and nursing education, discussion of the block duration, expected sensory and motor deficits, and a plan for pain management as the block diminishes, is the final element required for success ...

N2 - Diaphragmatic paralysis due to phrenic nerve block is a frequent complication of brachial plexus blocks performed above the clavicle. Farrar et al. reported incidences of 36, 36, and 38%, respectively, when routine chest x-rays were taken 4 h following interscalene, subclavian perivascular, and Kulenkampff supraclavicular techniques of brachial plexus blocks. Knoblanche demonstrated a higher incidence of 67% when fluoroscopic exmainations were performed to evaluate diaphragmatic movement in 15 patients within 3 h following subclavian perivascular brachial plexus blocks. Reports of the diagnosis of phrenic nerve block have previously relied upon clinical symptomatology, plain chest x-ray, or fluoroscopy. Recently, we have used a double-exposure technique that has allowed us to easily detect the presence or absence of phrenic ...
Nerve block therapy is generally an injection of local anesthetic injected directly into the affected nerve associated with the pain. However, nerve blocks can be used in several ways to treat the patient. First, nerve blocks can be used to treat acute pain in a specific part of the body. Nerve blocks can also be used on a temporary basis to locate which nerves are affected by the pain. This is called a diagnostic nerve block. Nerve block therapy has become an effective and trusted way to treat chronic pain. Many people who suffer from chronic pain receive nerve block therapy on a regular basis. Nerve block therapy is a safe alternative to surgery to control pain and return the patient to normal mobility and function. At OC Wellness Physicians, we take a comprehensive and thorough approach to treating severe and chronic pain. After meeting with one of our healthcare professionals, they can determine if nerve blocks therapy is right for you. Our goal is to not simply mask the pain, but cure the ...
There are many causes of peripheral neuropathy. Peripheral nerve blocks for the treatment of peripheral neuropathy involve single or multiple injections of agents or a combination of agents including local anesthetics (such as bupivacaine or lidocaine) with or without corticosteroids into or near peripheral nerves or a nerve ganglion. A peripheral nerve block attempts to block or interrupt the conduction of pain signals to the brain and provide temporary or permanent relief from chronic neuropathic pain conditions. The peer-reviewed medical literature includes numerous systematic reviews and practice guidelines evaluating the use of nerve blocks for the diagnosis and treatment of neuralgias and neuropathic pain conditions supporting the use of peripheral nerve blockade. However, there is a paucity of well-designed trials and trials with adequate long-term follow-up addressing the use of peripheral nerve blocks for the treatment of peripheral neuropathy. There are many small case series studies ...

An updated systematic review of the diagnostic utility of selective nerve root blocks. Pain Physician. 2007 Jan; 10(1):113-28 ...
A selective nerve block (SNRB) is the injection of a local anesthetic along a specific nerve root. This procedure is used primarily to diagnose nerve root compression. SNRB injections are isolated to various locations along the spine to determine which nerve root is causing the pain. If the patients pain dissipates after the injection at a particular nerve root, it can be inferred that the source of pain was being generated at the selected nerve root. Along with acting as a diagnostic tool, SNRBs can alleviate the discomfort associated with nerve root compression when used with an injectable steroid.. Administering a selective nerve block only takes a few minutes, but it is recommended to allow an hour for the entire visit, including a pre-operative consultation with the physician as well as post-operative observation.. What Happens during Selective Nerve Blocks?. A selective nerve block is performed by injecting a local anesthetic adjacent to vertebral foramina along the spine from which nerve ...
Ultrasound-guided peripheral nerve block is a procedure used in anesthesia that allows real-time imaging of the positions of the targeted nerve, needle, and surrounding vasculature. This improves the ease of performing the procedure, increases the success rate, and may reduce the risk of complications. It may also reduce the amount of local anesthetics requried, while reducing the onset time of blocks. Brull, Richard; Perlas, Anahi; Chan, Vincent W. S. (16 April 2007).

Magnetic Field Interactions: While the FlexTip Plus Epidural Catheter and the StimuCath Continuous Peripheral Nerve Block Catheter displayed relatively high magnetic field interactions during in vivo testing, it should be noted that these devices are maintained in place by means of suture material and bandages/tape and, as such, sufficient counter-forces are present that will prevent movement or dislodgement of the FlexTip Plus Epidural Catheter and the StimuCath Continuous Peripheral Nerve Block Catheter in situ. Therefore, during the intended in vivo use of the FlexTip Plus Epidural Catheter and the StimuCath Continuous Peripheral Nerve Block Catheter, these devices will not present an additional risk or hazard to a patient in the 3-Tesla or less MRI environment with regard to translational attraction or torque. ...
Peripheral nerve blocks reduced edema and temperature increase in our patients after surgery. This is the first study testing the effect of peripheral nerve block on clinical inflammation after surgery. One limitation of our study is caused by the fact that we could not perform a blinded study because of the sensory effects of the block and the visibility of the catheter during postoperative evaluation. As in a previous clinical study on knee surgery,35 we used the combination of circumference and temperature measurements to evaluate clinical inflammation. Previous experimental studies in humans have used similar clinical criteria (i.e. , flare, erythema, temperature) to evaluate inflammation.22,23,26,28-30,36 The precise mechanisms underlying the observed antiedematous effect of peripheral nerve block is unknown. First, in the absence of a change in markers of inflammation, one cannot exclude that the reduction of edema may have been due, at least in part, to other factors such as improved ...

Local anesthetic nerve block (local anesthetic regional nerve blockade, or often simply nerve block) is a short-term nerve block involving the injection of local anesthetic as close to the nerve as possible for pain relief. The local anesthetic bathes the nerve and numbs the area of the body that is innervated by that nerve. The goal of the nerve block is to prevent pain by blocking the transmission of pain signals from the surgical site. The block provides pain relief during and after the surgery. The advantages of nerve blocks over general anesthesia include faster recovery, monitored anesthesia care vs. intubation with an airway tube, and much less postoperative pain. Local anesthetics act on the voltage-gated sodium channels that conduct electrical impulses and mediate fast depolarization along nerves. Most of the local anesthetics target open channels and prevent ion flow. Local anesthetics also act on potassium channels, but they block sodium channels more. Lidocaine preferentially binds ...

Continuous nerve blocks have a number of advantages for both the surgeon and the patient, but what exactly are they?. Continuous peripheral nerve blocks (CPNBs) are used in a number of surgeries that before would necessitate an overnight stay in a hospital for postoperative pain control. A surgeon places a pain catheter in the vicinity of the target nerve which acts as a conduit for the continuous flow of anesthetic. The technique provides target-specific analgesia for a variety of surgeries and gets patients through the first 48 hours after surgery with little or no pain medication.. Continuous nerve blocks decrease the time it takes for a patient to be cleared for discharge from the hospital, giving many patients the chance to return home on the same day of surgery. Theres also very little hospital readmission related to pain control associated with the procedure.. For all the advantages continuous nerve blocks have, they arent without obstacles. Here are five tips for surgeons to help ...

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 ...

Some of the different types of nerve blocks that are used include:. ...
Pain following abdominal surgery is managed with the use of thoracic epidural analgesia (TEA) where the epidural is inserted in the spine at the level of scapula The risks due to TEA include difficulty with insertion, failure in up to 40% of patient in the perioperative period, fall in blood pressure and a rare devastating complication of paralysis either due to bleeding or infection. Injury to spinal cord is also a feared complication. Therefore alternative techniques need to be evaluated. Paravertebral block (PVB) has been documented to provide pain relief following abdominal surgery using an earlier technique which posed the risk of puncture of the covering to the lung (pleura) resulting in pneumothorax. The current technique involves the use of curled catheters inserted using ultrasonography to lie outside the pleura where the nerves travel thus reducing the chances of pneumothorax and catheter migration. Objective of the current study is to compare the efficacy and safety of bilateral PVB ...

assist with spinal placement. The authors have found L5-S1 space using ultrasonography many times where other colleagues have struggled to place a spinal. Careful dose reduction in spinal anesthesia is important in elderly patients (5-7.5 mg). A recent article examined the minimal doses of spinal local anesthetic for hip fracture when using titration via a spinal catheter.[2] Using the Dixon Massey method, the authors found that doses as low as 0.24 mL of 0.5% isobaric bupivacaine may be all that is required initially. The cumulative dose was just over 1 mL of 0.5% isobaric bupivacaine. This dose is much lower than is normally given by most practitioners. With their low dose, they found less hypotension than previously reported with larger doses of local anesthetic. As part of the time-out at surgery, a discussion should occur about keeping the peripheral nerve catheter or pulling it. The catheter should be pulled in the operating room if there is a realistic expectation that the patient will ...

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 ...
The investigation by Eng et al. found that 76% of total hospital costs were variable (change in proportion with patient volume). This is a high percentage relative to what is typically found as the majority of hospital costs are fixed overhead (e.g., buildings, equipment, and salaried labor). This difference could be due to several factors including whether labor is considered fixed or variable, or the use of different accounting methodologies at different facilities. Regardless, it suggests that practices with a lower percentage of variable costs than 76% of this Canadian study (commonly less than 20% within the United States)11 could anticipate savings of much less than the 9% reported by Eng et al. Moreover, if per diem (i.e., daily) payments were decreased with rapid hospital discharge (common for payers within the United States), and if the costs of an ambulatory CPNB program are included (e.g., ultrasound capital outlay), any cost savings might actually become a deficit ...
A sympathetic nerve block is a relatively safe procedure. You can usually go home afterward and return to your normal activities after a day of rest. If you had IV sedation, youll need to have someone drive you home.. Side effects after a sympathetic nerve block may include temporary soreness, bleeding, bruising, a feeling of warmth, or some weakness. If youve received a nerve block in the stellate ganglion, you may experience some temporary voice changes, eyelid droop, or difficulty swallowing. Until swallowing is back to normal, avoid large bites of food and sip liquids carefully.. Depending on the reason for the block, physical therapy, talk therapy, and pain medicine may all be part of your treatment as well. In most cases, you will be given a series of blocks to get the best possible response.. Sympathetic nerve blocks dont work for everyone. Also, the pain relief they give may lessen over time. But for some, a sympathetic nerve block may provide weeks or months of pain relief. ...

Part of pain management and recovery from surgery may involve the use of a peripheral nerve block. These videos explain what a peripheral nerve block is and how you can use it to control pain in the hospital and after you return home.
Nerve blocks are useful for providing pain relief during surgery, that is for surgical pain, after surgery while recovering in the hospital, or for post-operative pain, and for the control of chronic pain conditions like herniated disc pain. Nerve blocks are rarely permanent in that they are not intended to cause nerve injury. Local anesthetics like lidocaine are often deposited on or near a nerve or a group of nerves that need to be blocked.

Background: The aim of this study was to compare the analgesic efficacy of subacromial bursae block (LA), suprascapular nerve block (SSB), and interscalene brachial plexus block (ISB) after arthroscopic shoulder surgery. Methods: 91 patients scheduled to undergo an arthroscopic shoulder acromioplasty under GA in an outpatient setting were included. The patients were prospectively randomized into 4 groups: 1) interscalene brachial plexus block, 2) suprascapular nerve block, 3) subacromial bursae block, 4) control group for comparison. Pain scores (VAS), supplemental analgesia, and side effects were recorded in the recoveryroom, 4 hours and 24 hours after surgery. Results: Group ISB had significantly lower pain scores at rest in the postanesthesia care unit than the SSB group (p = 0.037) and the control group (p = 0.0313). The same results were seen 4 hours follow-up. The LA group had significantly lower pain scores at rest in the postanesthesia care unit than the control group (p = 0.046) and after 4
BACKGROUND: Supraclavicular brachial plexus blocks are not common in children because of risk of pneumothorax. However, infraclavicular brachial plexus blocks have been described in paediatric patients both with nerve stimulation and ultrasound (US)-guidance. US-guidance reduces the risk of complications in supraclavicular brachial plexus blocks in adults.. OBJECTIVE: To compare the success rate, complications and time of performance of US-guided supraclavicular vs infraclavicular brachial plexus blocks in children.. MATERIAL AND METHODS: Eighty children, 5-15 years old, scheduled for upper limb surgery were divided into two randomized groups: group S (supraclavicular), n = 40, and group I (infraclavicular), n = 40. All blocks performed were exclusively US-guided, by a senior anaesthesiologist with at least 6 months of experience in US-guided blocks. For supraclavicular blocks the probe was placed in coronal-oblique-plane in the supraclavicular fossa and the puncture was in-plane (IP) from ...

The use of ultrasound in regional anesthesia enables reduction in the local anesthetic volume. The present study aimed to determine the minimum effective volume of 0.375% bupivacaine with epinephrine for interscalene brachial plexus block for shoulder surgery. Following approval by the Research Ethics Committee, patients with a physical condition of I or II according to the American Society of Anesthesiologists, between 21 and 65 years old and subjected to elective surgery of the shoulder and interscalene brachial plexus block will be recruited. The volume of the anesthetic will be determined using a step-up/step-down method and based on the outcome of the preceding block. Positive or negative block results in a 1mL reduction or increase in volume, respectively.

It gets hard to describe what to do when you feel pain or discomfort in the chest. Is it a heart attack or another, less serious problem? Since chest pain can be a sign of a heart attack, if the pain is due to heart disease, it is important to seek help and get treatment as quickly as possible.. One of the ways of treating chest pain is to undergo the Intercostal Nerve Block Treatment. Intercostal nerve blocks are popular with physicians treating chronic pain and inflammation in the abdomen or chest for a prolonged period of time. Patients with pain that is resistant to opioid treatments, or who wishes to avoid using them, often find intercostal nerve blocks are a practical and less risky pain management option. Surgeons may also use intercostal nerve blocks as part of analgesia during major thoracic or abdominal procedures.. An intercostal nerve block is an injection of medication that helps relieve pain in the chest area caused by a herpes zoster infection (or shingles) or a surgical ...

Peripheral nerve blocks are effective in treating acute pain, thereby minimizing the requirement for opiate analgesics. Fractured neck of femur (FNF) is a common, painful injury. The provision of effective analgesia to this cohort is challenging but an important determinant of their functional outcome. We investigated the analgesic efficacy of continuous femoral nerve block (CFNB) in patients with FNF. Following institutional ethical approval and with informed consent, patients awaiting FNF surgery were randomly allocated to receive either standard opiate-based analgesia (Group 1) or a femoral perineural catheter (Group 2). Patients in Group 1 received parenteral morphine as required. Those in Group 2 received a CFNB comprising a bolus of local anaesthetic followed by a continuous infusion of 0.25% bupivacaine. For both Groups, rescue analgesia consisted of intramuscular morphine as required and all patients received paracetamol regularly. Pain was assessed using a visual analogue scale at rest and

Introduction: In this prospective randomized controlled study, we investigated the efficacy of obturator nerve block (ONB) on adductor muscle spasm and related short-term outcomes and complications in patients who underwent transurethral resection of lateral wall-located bladder tumours (TURBT).. Methods: Between July 2014 and February 2015, 70 patients scheduled to undergo TUR of lateral bladder wall tumours were enrolled in the study. All patients were preoperatively evaluated by cystoscopy and imaging tools and selected according to localized tumours on the lateral bladder wall. Patients were randomly allocated to Group SA (35 patients who underwent only spinal anesthesia) and Group ONB (35 patients who underwent spinal anesthesia combined with ONB by the nerve stimulator). An independent observer, blinded to the approach, evaluated the obturator signs, including adductor muscle contraction, bladder perforation, and completeness of the resection during the TURBT procedure.. Results: The ...

PY - 2013/9. Y1 - 2013/9. N2 - Purpose/Objective: Piriformis syndrome is thought to cause of 6-8% of sciatica. Injection of local anaesthetic and steroid into piriformis muscle is an established treatment option. A combined technique of ultrasound with motor stimulation has been advocated for accurate confirmation of piriformis pain and avoidance of sciatic nerve block. We report a case of sciatic nerve block despite taking the above precautions. Materials and Methods: The patient was positioned prone with intravenous access and standard monitoring in place. A pillow under the pelvis optimised piriformis visualization. A 2-5 Hz curvilinear probe placed horizontally over the posterior superior iliac spine was moved downwards and laterally to identify piriformis and the sciatic nerve. Under ultrasound ...
Background: Due to the importance of pain control after abdominal surgery, several methods such as transversus abdominis plane (TAP) block are used to reduce the pain after surgery. TAP blocks can be performed using various ultrasound-guided approaches. Two important approaches to do this are ultrasound-guided lateral and posterior approaches. This study aimed to compare the two approaches of ultrasound-guided lateral and posterior TAP blocks to control pain after cesarean section. Materials and methods: In this double-blind clinical trial study, 76 patients scheduled for elective cesarean section were selected and randomly divided into two groups of 38 and underwent spinal anesthesia ...

The suprascapular nerve provides sensory innervation to the glenohumeral joint (shoulder). Suprascapular nerve block is indicated for the relief of acute shoulder pain e.g., after shoulder surgery and is more effective when combined with blockade of the axillary nerve. It is also useful for the diagnosis and treatment of chronic shoulder pain secondary to bursitis, arthritis, degenerative joint and rotator cuff disease. Some studies show that blockade using local anesthetic and steroid can alleviate pain and disability in certain chronic shoulder pain conditions.. An intercostal nerve block is an injection of medication that helps relieve pain in the chest area caused by a herpes zoster infection (or shingles) or a surgical incision.
