CONTEXT Patients receiving femoral nerve blocks for total knee arthroplasty (TKA) have been shown to have a high incidence of postoperative falls, which has been attributed to weakening of the quadriceps muscles. Local injection of analgesic medication that allows for full motor function of the quadriceps and, therefore, better progress through inpatient physical therapy and decreased hospital ...

INTRODUCTION This study was aimed to compare the axillary approach performed through multiple injection method and vertical infraclavicular approach performed through single injection method in terms of the sensory and motor block onset, quality, and extent of blocks of brachial plexus in uremic patients who underwent arteriovenous fistula surgery. METHODS Forty patients scheduled for creatio...

OBJECTIVE To study the effects of the site of intravenous injection of adenosine and to assess the site of action of adenosine in the heart by correlating cardiac effects with bolus transit. METHODS Ten patients undergoing routine technetium (Tc-99m) gated blood pool ventriculography consented to the coadministration of intravenous adenosine. The dose of adenosine required to produce heart bl...

Objective—To study the eVects of the site of intravenous injection of adenosine and to assess the site of action of adenosine in the heart by correlating cardiac eVects with bolus transit. Methods—Ten patients undergoing routine technetium (Tc-99m) gated blood pool ventriculography consented to the coadministration of intravenous adenosine. The dose of adenosine required to produce heart block ...

BACKGROUND Nerve puncture by the block needle and intraneural injection of local anesthetic are thought to be major risk factors leading to neurologic injury after peripheral nerve blocks. In this study, the author sought to determine the needle-nerve relation and location of the injectate during ultrasound-guided axillary plexus block. METHODS Using ultrasound-guided axillary plexus block (1...

A prospective, randomized, double-blind study was performed to investigate whether altering the rate of injection of local anaesthetic through a Whitacre needle had any effect on the spinal block achieved. Twenty patients scheduled for elective urological surgery under spinal anaesthesia received an injection of 3 ml of 0.5% plain bupivacaine either by hand (fast) over 10 s (18 ml min(-1)) or b...

UNLABELLED Background. A study was designed to compare the efficacy of anesthesia between transthecal digit block (TDB) and single injection volar subcutaneous block. METHODS A 36-patient, randomized, controlled, prospective investigation was undertaken. The parameters included the onset of time to achieve anesthesia, visual analog scale pain score during the infiltration, and anesthesia ...

a 25-year-old afghan male was presented to the emergency department with femoral shaft fracture following fall from the height. the patient was subjected to femoral nerve block and general anesthesia. first try for performing nerve block led to vascular puncture. therefore, the needle was removed and re-inserted 1 cm lateral to first puncture site and dex injected slowly with aspiration check a...

The phenol nerve block has been widely used in clinical practice for spasticity reduction, but the correlation between the dosage of phenol and its effectiveness has seldom been discussed. The objective was to determine the optimal duration of phenol in contact with the nervous tissue and to investigate the dose-response relationship of 5% aqueous phenol solution by percutaneous nerve block in ...

Shoulder pain is a common complaint in elder population and may cause an important functional disability. The aim of this study was to compare the effects of suprascapular nerve block with those of steroid injection in patients with non-specific shoulder pain. A total of 60 patients with shoulder pain lasting for more than four weeks were included in this study. After 1:1 randomization, patient...
