Perioperative Total Parenteral Nutrition in Surgical Patients

·1991·New England Journal of Medicine

Abstract

BACKGROUND: We undertook this study to test the hypothesis that perioperative total parenteral nutrition (TPN) decreases the incidence of serious complications after major abdominal or thoracic surgical procedures in malnourished patients. METHODS: We studied 395 malnourished patients (99 percent of them male) who required laparotomy or noncardiac thoracotomy. They were randomly assigned to receive either TPN for 7 to 15 days before surgery and 3 days afterward (the TPN group) or no perioperative TPN (the control group). The patients were monitored for complications for 90 days after surgery. RESULTS: The rates of major complications during the first 30 days after surgery in the two groups were similar (TPN group, 25.5 percent; control group, 24.6 percent), as were the overall 90-day mortality rates (13.4 percent and 10.5 percent, respectively). There were more infectious complications in the TPN group than in the controls (14.1 vs. 6.4 percent; P = 0.01; relative risk, 2.20; 95 percent confidence interval, 1.19 to 4.05), but slightly more noninfectious complications in the control group (16.7 vs. 22.2 percent; P = 0.20; relative risk, 0.75; 95 percent confidence interval, 0.50 to 1.13). The increased rate of infections was confined to patients categorized as either borderline or mildly malnourished, according to Subjective Global Assessment or an objective nutritional assessment, and these patients had no demonstrable benefit from TPN. In contrast, severely malnourished patients who received TPN had fewer noninfectious complications than controls (5 vs. 43 percent; P = 0.03; relative risk, 0.12; 95 percent confidence interval, 0.02 to 0.91), with no concomitant increase in infectious complications. CONCLUSIONS: The use of preoperative TPN should be limited to patients who are severely malnourished unless there are other specific indications.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
