A randomized controlled trial: Comparison of one-per-mil tumescent technique and tourniquet in surgery for burn hand contracture in creating clear operative field and assessment of functional outcome

BackgroundThis study aims to compare the use of one-per-mil tumescent solution (a mixture of epinephrine and 0.2% lidocaine in a ratio of 1:1,000,000 in normal saline solution) and tourniquet to create clear operative fields and to evaluate the functional outcomes after post burn hand contracture surgery.MethodsThe subjects of this randomized controlled trial were divided into one-permil tumescent technique and tourniquet group for a similar surgical procedure. Three independent assessors evaluated the clarity of the operative fields through recorded videos for the first 15 min and the first 10-minute of each hour of the surgery. Functional outcome was evaluated at least three months postoperatively using total active and passive motion (TAM and TPM) of each digit. Malondialdehyde (MDA) and tumor necrosis factor alpha (TNF-α) were tested during baseline (5 min before the procedures), ischemia phase, and reperfusion phase (a phase when the blood flow returned to the tissue).Results35 subjects were included in this study: 17 in the tumescent group and 18 in the tourniquet group. We found a significant difference in the clarity of operative field between tumescent and tourniquet groups, 5 vs 35 bloodless operative fields, respectively (p < 0.05). TAM and TPM of each digit before surgery and 3 months postoperatively showed no significant difference between both groups (p > 0.05). Furthermore, we found no difference in MDA and TNF-α levels between both groups at their respective phases.ConclusionsThe use of one-per-mil tumescent technique does not replace tourniquet use to create bloodless operative fields in burned hand contracture surgery. However, the postoperative functional results were similar in both groups showing that tumescent technique can be used as an alternative to tourniquet without compromising outcomes. The MDA and TNF-α examinations do not provide conclusive outcomes regarding ischemia and reperfusion injury.     

Development and implementation of an innovative intern training programme

The quality of medical education during internship is a cause for concern. This paper describes a structured educational programme for interns that was based around learning modules, clinical attachments and bedside teaching. The programme was incorporated into the term rotation of interns within an Area Health Service, and evaluated. Learning modules were timetabled by a Programme Coordinator and interns were reminded to attend. Clinical attachments were organized by the interns from a list of willing supervisors. Attendance at timetabled learning modules averaged 67%, which was greater than the 27% attendance at clinical attachments. Both sessions received high ratings for quality and clinical relevance. This structured education programme was based upon adult learning methods and was both feasible and well received by interns. Intern training programmes need to be programmed into the working week to ensure attendance, and modified following evaluation by interns. Such programmes should be considered by all hospitals to which interns are allocated.

A trial of relapse prevention with severely dependent male problem drinkers

Over the last two decades, relapse prevention has emerged as a major focus of the treatment of drug problems. Few studies have demonstrated any impact on generally high relapse rates. In this paper the outcome of a controlled trial of a relapse prevention programme with male problem drinkers (n=60) attending an Alcohol Treatment Unit is reported. Subjects who met the inclusion criteria were allocated to a relapse prevention (n=20) procedure or a discussion (n=20) or no-additional treatment (n=20) control procedure. Subjects were followed-up at 6 and 12 months by the first author. The relapse prevention programme was associated with significantly greater increases in pre- and post-treatment self-efficacy compared to the discussion control group and significantly greater probability of total abstinence than all controls over the first 6-month follow up. In addition, the relapse prevention programme was associated with significantly longer survival time to an initial lapse and relapse than the controls. At 12-month follow-up, treatment effects had been eroded. It was concluded that the relapse prevention programme was an effective treatment in the short term and that longer-term impact may require greater focus on maintenance factors, such as the individual's environment.
