Laparoscopic surgery offers patients a significant number of advantages, including a reduction in pain and cosmetic injury that facilitates early ambulation and a rapid return to normal activities. Although the surgery is of a minimally invasive nature, there are a number of specific physiological alterations occurring as a result of creating the(More)
This study compared the posterior and popliteal fossa approaches for sciatic nerve block. Patients scheduled to undergo foot surgery were allocated randomly into one of two groups: group A (n = 20) received sciatic nerve block via the posterior approach and group B (n = 20) received a block using the popliteal fossa approach. All blocks were performed with(More)
Two groups of 12 patients had a sciatic nerve block performed with 20 ml of either ropivacaine 7.5 mg ml(-1) or bupivacaine 5 mg ml(-1). There was no statistically significant difference in the mean time to onset of complete anaesthesia of the foot or to first request for post-operative analgesia. The quality of the block was the same in each group.(More)
This double-blind study investigated the rectal administration of midazolam as an alternative to general anaesthesia for elective computerized tomography (CT) of the brain. Thirty children were randomly allocated to receive either midazolam 0.3 mg kg-1 (Group 1) or midazolam 0.6 mg kg-1 (Group 2) by the rectal route. Sedation was obtained in 13 children in(More)
We performed a double-blind, randomised controlled trial to assess the effectiveness of a continuous-infusion brachial plexus block with levobupivacaine compared with that of a standard single injection for the management of post-operative pain after surgery on the shoulder. Eight patients were randomised to receive a pre-operative brachial plexus block(More)
the scope of this book, but also introduces something on the style of the book. The book is a detailed report on the findings of an interdisciplinary study team. The approach has been a “concerted action”, and the approach of the team has been comprehensive, complex and intensive. The book following a report format has Chapter 1 providing an introduction(More)
This prospective, randomized, double-blind study compared two techniques of axillary brachial plexus block using a peripheral nerve stimulator. Both groups received initial musculocutaneous nerve block followed by either a single injection on median nerve stimulation (group 1) or a double injection divided between median and radial nerves (group 2). All 60(More)
A double-blind randomised clinical trial was undertaken in 40 patients undergoing major abdominal surgery. Postoperative pain relief was provided using epidural infusions of 0.06% bupivacaine with fentanyl 4 micrograms.ml-1 (n = 20) (group F) or with pethidine 1.5 mg.ml-1 (n = 20) (group P). Postoperative pain scores using a visual analogue scale (0-100 mm)(More)
