Review Meta Analysis
Systematic review of spinal anaesthesia using bupivacaine for ambulatory knee arthroscopy.
The use of lidocaine in spinal anaesthesia is associated with transient neurological syndrome (TNS). Bupivacaine has a lower incidence of TNS as an alternative but it may have a prolonged action. This study systematically reviews the literature about the recovery profile of patients undergoing spinal anaesthesia, using bupivacaine for arthroscopic knee surgery. ⋯ The results of our systematic review suggest that 4-5 mg of hyperbaric bupivacaine can effectively produce spinal anaesthesia for knee arthroscopy with unilateral positioning. Ropivacaine or the addition of adjuvants did not improve the recovery time. There is a need for tighter RCTs with more consistent endpoints.

Recent studies suggest that implicit memory (especially perceptual implicit memory) persists during adequate general anaesthesia in adults. Studies in children, however, have failed to demonstrate implicit memory during general anaesthesia, possibly because of differences in methodological design. We therefore designed a prospective study with the aim of evaluating implicit memory in children undergoing general anaesthesia, using a perceptual memory test based on the mere exposure effect, previously tested in a control group. ⋯ The use of a perceptual implicit memory test based on the mere exposure procedure in children failed to reveal any evidence of implicit memory under general anaesthesia.

Echocardiography has been shown to positively impact on the management of the critically ill patient. However, many published studies have a significant bias towards inclusion of cardiothoracic patients. We present an audit of the impact of echocardiography on the management of patients in a district general hospital intensive care unit (ICU). ⋯ Echocardiography may have a significant impact on the management of patients in the general ICU. We recommend that appropriate training in echocardiography should be incorporated into the intensive care curriculum in the UK.

No data for patients with failed back surgery syndrome (FBSS) based on the location of adhesions separated by epiduroscopic adhesiolysis have been reported. ⋯ Progressive epidural imaging after adhesiolysis suggested that pain was caused by re-adhesion around the nerve root. Since re-adhesion of the nerve root required some time, the effect of adhesiolysis was maintained for extended periods in these cases. We suggest that epiduroscopic adhesiolysis is an effective therapy for FBSS patients, and that adhesiolysis of the nerve root may exhibit the long-term (24 weeks) efficacy in patients with pain.
