Searching for a differential spinal block between dependent and nondependent sides, we evaluated a prospective randomized time-response study of the influence of the duration of lateral decubitus on the spread of hyperbaric local anesthetic solution during spinal anesthesia in 60 patients undergoing lower limb surgery. In a lateral position with the(More)
The aim of this study was to compare hypobaric solutions of tetracaine and bupivacaine in 30 geriatric patients undergoing surgical repair of hip fractures while under continuous spinal anesthesia. Tetracaine 1% and bupivacaine 0.5% were mixed with distilled water to prepare hypobaric 0.25% solutions. In a double-blind fashion, all patients received 3 ml(More)
The extent of sensory block during spinal anaesthesia is unpredictable and is influenced by many factors, mainly patient position, site of injection, baricity and the dose of drug injected. Among other factors, cerebrospinal fluid (CSF) density has been advocated to affect subarachnoid distribution of local anaesthetics. In this study, we have investigated(More)
BACKGROUND The attempts to explain the unpredictability of extent of spinal block provided by plain local anesthetic solutions have resulted in many clinical reports; however, causes of this uncertainty are as yet unknown. Recently, normal values of the human cerebrospinal fluid densities have been studied showing important interindividual variations,(More)
UNLABELLED We tested the effect of epinephrine added to 20 mL ropivacaine 0.5% and 0.2% on postoperative analgesia via a femoral catheter after total knee replacement. Forty-one patients undergoing total knee replacement under combined peripheral block/general anesthesia were randomly allocated to two groups. After insertion of a femoral catheter, 21(More)
BACKGROUND We designed this study to compare the postoperative analgesic effects of intrathecal morphine and nalbuphine, the endpoints being onset and offset of action. METHODS Geriatric patients scheduled for elective total hip replacement under continuous spinal anaesthesia were randomized to two double-blinded groups in the recovery room as soon as(More)
PURPOSE Preoperative anxiety in relation to anesthesia remains for many patients a major subject of concern. The aim of the present study was to compare the level of preoperative anxiety in patients assessed in an outpatient consultation clinic with the anxiety level of those having been assessed by the anesthesiologist after entering the hospital. METHOD(More)
BACKGROUND Diagnosis of ventilator associated pneumonia can be made by quantitative cultures of bronchoalveolar lavage fluid or of protected specimen brushings, though cultures require 24-48 hours to provide results. In 80% of cases aerobic Gram negative bacteria are the cause. METHODS A rapid diagnostic method of assessing the endotoxin content of lavage(More)
