[The Bengmark tube in surgical practice and in the critically ill patient].
Enteral nutrition (EN) is increasingly used to minimize the rate of septic complications related to bacterial translocation, due to its effectiveness and low cost. Bengmark's self-propelling auto-positioning feeding tube (SPT) absorbs and uses gut motility for rapid transport to the upper small intestine, thereby allowing uninterrupted EN both in surgical and critically ill patients. We report on our experience with 175 SPTs applied over the period from December 1996 to February 2000, and analyse the safety, compliance, and indications of SPT in surgical and ICU practice. Open study: feasibility of insertion, time and rate of placement, compliance and complications related to the tube or to EN were studied. SPTs were successfully placed in 40 patients before liver resection, in 32 patients before extensive maxillo-facial surgery MFS and prior to colon resections in 10 cases. SPTs were also applied in 56 patients with acute vascular neurological diseases, 22 in pancreatic diseases and in another 15 critically ill patients. 92.5% of SPT's crossed the pylorus, while only 7.5% stopped in the stomach and 3.4% in the duodenum; 89.14% reached the first jejunal loop. The tip of the tube reached its final position within a mean period of 5.2 hours, 8% instantly and all within 24 hours. Enteral nutrition was started immediately after introduction of the tube into the stomach. The compliance was excellent, even in maxillo-facial surgery patients: only 2/76 patients (2.6%) showed poor compliance. There were no cases of aspiration pneumonia or other complications related to SPT. Polymeric nutrition was usually supplied at a starting flow rate of 45 ml/hour and rapidly increasing over the following 48 h. Eleven patients experienced diarrhoea and 6 abdominal distension, leading to a temporary reduction of the EN flow rate. Clogging of the SPT occurred in 13 patients: 7/13 were cleansed with pancreatic enzymes, but 6 had to be replaced. SPT is ideal for intensive EN and is characterised by minimal complications and excellent patient compliance.
