Applications of bispectral index monitoring in the pediatric intensive care unit

The bispectral index (BIS) monitor is an electroencephalographic recording device that generates a single numeric value. It has traditionally been used to measure anesthetic depth and avoid awareness in the operating room setting. In this report, the authors present different scenarios in the pediatric intensive care unit that demonstrate the potential applications of the BIS monitor outside of the operating room setting. The scenarios presented include use of the BIS monitor during titration of barbiturate coma, procedural sedation, sedation assessment during mechanical ventilation, and sedation while administering potentially confounding medications. Previous reports regarding the use of the BIS monitor in such scenarios and potential future applications are reviewed     

Immunosuppression in renal transplantation: Long-term clinical trial of a double versus triple therapy regimen

Summary: Sixty-nine renal allograft recipients were randomized to two immunosuppressive regimens: 35 patients received cyclosporine A and prednisolone (PC) while 34 patients received low dose cyclosporine A, prednisolone and short term azathioprine (PCA). the data of 66 patients (34 in PC and 32 in PCA groups) were analysed. the median follow-up periods were 62 months for the PC group and 60 months for the PCA group. There was no difference in graft survival between the two groups but five patients died in the PC group compared to none in the PCA group (graft survival: 88 vs 90% at 1 year and 82 vs 82% at 5 years, P = not significant at any time point; patient survival: 90 vs 100% at 1 year and 88 vs 100% at 5 years, P = 0.05 at 5 years). There was a trend for patients in the PCA group to develop earlier and more frequent rejections (not significant; P = 0.106 and P = 0.062, respectively). There were also more episodes of acute cyclosporine A nephrotoxicity and cytomegalovirus (CMV) infection in the PC group. the mean serum creatinine at 5 years was significantly higher in the PCA group when compared to the PC group (179.8 ± 76.5 μmol/L vs 154.7 ± 41.0 μmol/L; P =0.05). We found that both therapeutic regimens were effective in preventing renal allograft rejections. However, double therapy was associated with higher patient mortality secondary to infection. Patients on triple therapy, on the other hand, were more prone to develop rejections in the early post-transplant period and were associated with less favourable renal function in the long run.     

Percutaneous cholecystostomy: an alternative to surgical cholecystostomy for acute cholecystitis?

Emergency percutaneous cholecystostomy was successfully performed in 39 of 40 attempted procedures in 37 hospitalized patients with possible acute cholecystitis. All cholecystostomies were performed with ultrasound guidance and preferentially with the transhepatic route, and all but four were performed at the patient's bedside. The patients had been hospitalized an average of 27 days before the procedure. Twenty-two of the 37 patients (59%) eventually died during hospitalization because of other medical or surgical problems. Only minor complications related to percutaneous cholecystostomy placement occurred in this series: catheter dislodgment without sequelae (n = 2) and significant abdominal pain (n = 2). Technical problems included guide-wire buckling during catheter insertion (n = 1) and failed attempted cholecystostomy (n = 1). Percutaneous cholecystostomy is a safe alternative to surgical cholecystostomy in the treatment of patients suspected of having acute cholecystitis.     

The influence of in-pregnancy smoking cessation programmes on partner quitting and women's social support mobilization: a randomized controlled trial [ISRCTN89131885]

Background  

Smoking cessation interventions in pregnancy could influence a woman's social behaviour and her partner's smoking behaviour, but this has not been examined in any published randomized trials.     

Peri-operative outcomes for pancreatoduodenectomy in India: a multi-centric study

Background:

There have been an increasing number of reports world-wide relating improved outcomes after pancreatic resections to high volumes thereby supporting the idea of centralization of pancreatic resectional surgery. To date there has been no collective attempt from India at addressing this issue. This cohort study analysed peri-operative outcomes after pancreatoduodenectomy (PD) at seven major Indian centres.

Materials and Methods:

Between January 2005 and December 2007, retrospective data on PDs, including intra-operative and post-operative factors, were obtained from seven major centres for pancreatic surgery in India.

Results:

Between January 2005 and December 2007, a total of 718 PDs were performed in India at the seven centres. The median number of PDs performed per year was 34 (range 9–54). The median number of PDs per surgeon per year was 16 (range 7–38). Ninety-four per cent of surgeries were performed for suspected malignancy in the pancreatic head and periampullary region. The median mortality rate per centre was four (range 2–5%). Wound infections were the commonest complication with a median incidence per centre of 18% (range 9.3–32.2%), and the median post-operative duration of hospital stay was 16 days (range 4–100 days).

Conclusions:

This is the first multi-centric report of peri-operative outcomes of PD from India. The results from these specialist centers are very acceptable, and appear to support the thrust towards centralization.
