Comparative StudyCorrelation of APACHE II score, drainage technique and outcome in postoperative intra-abdominal abscess.
The APACHE II Score was used to stratify retrospectively severity of illness in 91 patients postoperatively undergoing drainage of intra-abdominal abscesses. The method of initial abscess drainage (percutaneous or operative) was selected by the attending physician. The two groups of patients, those whose initial drainage was performed percutaneously versus operatively were similar with respect to age, sex, abscess location and, most importantly, severity of illness as assessed by the APACHE II score calculated on the day of their abscess drainage. ⋯ While chi-square analysis demonstrated independence between outcome and drainage technique, outcome was dependent upon severity of illness (p less than 0.0005). Paradoxically, despite the attractiveness of a percutaneous technique for abscess drainage in the most ill patients, in this series, a better, although not statistically improved, chance for survival was noted with surgical treatment. We recommend that an objective severity scoring system be used whenever assessing results of treatment of intraabdominal infection and that surgical treatment not be avoided because the patient is considered to be too ill.

To identify predictors of postoperative congestive heart failure (CHF), a high-risk population, mainly hypertensive and diabetic patients undergoing elective general operations, was studied. Of the 254 patients, 6 per cent had postoperative CHF. Among patients with preoperative cardiac disease (that is, previous myocardial infarction, valvular disease or CHF), 17 per cent had postoperative CHF; in contrast with less than 1 per cent of those without cardiac disease (p less than 0.001). ⋯ Of note, postoperative failure rates were highest among patients with less than 500 milliliters per hour of net intake (input and output) (p less than 0.03). Risk for postoperative CHF was restricted to patients with preoperative symptomatic cardiac disease and was especially high if patients also had diabetes. Intraoperative fluctuations in mean arterial pressure increased the probability of postoperative failure, while the intraoperative administration of higher net volumes of fluid was associated with decreased risk.

Simple technique for long term central venous access in the patient with thrombocytopenic carcinoma.
A technique for the insertion of a central venous access device in the patient with thrombocytopenia is described. Using the Seldinger technique, a wire is placed into the internal jugular vein. A catheter tunneled from the anterior part of the chest is inserted through a peel-away sheath into the central venous system. The incision is then closed.
