The intra-articular injection of local anaesthetic is frequently used for pain relief after arthroscopy. There is, however, no published evidence of the analgesic effect of bupivacaine in the ankle. In a randomised, double-blind study, 35 patients undergoing arthroscopy of the ankle were allocated to receive intra-articular saline or bupivacaine. Pain was assessed using pain scores and addition...

Introduction. This study aimed to determine if preoperative psychological tests combined with simple pain prediction ratings could predict pain intensity and analgesic usage following cesarean delivery (CD). Methods. 50 healthy women undergoing scheduled CD with spinal anesthesia comprised the prospective study cohort. Preoperative predictors included 4 validated psychological questionnaires (A...

PURPOSE To evaluate the efficacy of a single shot "3-in-1" femoral nerve block for prosthetic hip surgery in association with general anaesthesia on post-operative analgesia. METHODS Forty patients, ASA 1 to 3, received sham block or "3-in-1" femoral nerve block, following Winnie's landmarks with a nerve stimulator, and 40 ml bupivacaine 0.5% with epinephrine were injected after induction of ...

OBJECTIVE To establish whether positive suggestions given to a patient under general anaesthesia reduce postoperative pain and analgesic requirements. DESIGN Prospective double blind randomised study. SETTING Operating theatre and gynaecology ward of a teaching hospital. PATIENTS 63 Woman undergoing elective abdominal hysterectomy were randomised to be played either a tape of positive sug...

Background: Enhanced recovery after thoracic surgery (ERATS) protocols use a combination of analgesics for pain control. We investigated the effect non-steroidal analgesic drugs (NSAIDs) on control by comparing patient levels and opioid requirements robotic pulmonary resections.

OBJECTIVE Recent studies have shown the positive effect of magnesium sulphate (MgSO4) on pain reduction and postoperative analgesic requirements in patients undergoing surgery. We assessed the effect of MgSO4 on intra-operative and postoperative analgesic requirements in patients undergoing lower abdominal gynecological laparotomy. MATERIALS AND METHODS This randomized clinical trial was cond...

Purpose. To develop a mathematical tool for decomposition of comeal topographic data into comprehensive optical components. Methods. The polar data values arising from each mire of the TM>1 cornea1 topographer were separated into spherical (average power), regdar astigmatic (2’ harmonic), and non-regular astigmatic components (l’, 3’, and higher harmonics) by Fourier series analysis. Averages o...

BACKGROUND Because magnesium blocks the N-methyl-D-aspartate receptor and its associated ion channels, it can prevent central sensitization caused by peripheral nociceptive stimulation. However, transport of magnesium from blood to cerebrospinal fluid (CSF) across the blood-brain barrier is limited in normal humans. The current study was designed to evaluate whether perioperative intravenous ma...
