A prospective trial was carried out to test the hypothesis that therapy with intravenous (IV) heparin sodium reduces the incidence of thrombotic complications related to the use of central venous catheters for parenteral nutrition. The patients studied were randomly allocated either to a group given heparin sodium, at a dosage of 5,000 IU/6 hr, or to a(More)
Primary angioplasty strategies have evolved dramatically, including increasing adjunctive use of stents and glycoprotein (GP) IIb/IIIa inhibitors. The purpose of this study was to examine the specific effects of these adjunctive therapies on long-term outcomes after primary angioplasty. From 1996 to 1998, 257 unselected, consecutive patients underwent(More)
OBJECTIVE To prospectively evaluate and compare the effect of liquid resin on lingual retainer failure after a 2-year follow-up. MATERIALS AND METHODS Fifty-two patients (26 males, 26 females) with a mean age of 18.3 ± 1.3 years at follow-up, were randomized into two groups: the resin group and the nonresin group. The lingual retainers in the resin group(More)
In a pilot study of 26 patients, a mixture of 50% nitrous oxide and 50% oxygen (N2O-O2) appeared to be an effective and safe analgesic for the incision and drainage of closed-space infections. The analgesic effect of N2O-O2, as measured by a Mean Analgesic Index, is augmented by both amnesic and dissociative effects, ie, patients remembered experiencing(More)
Sixty central venous catheterizations in 53 patients were prospectively studied with respect to phlebographic findings after prolonged parenteral nutrition. Phlebography was performed by a special technique on completion of the intravenous therapy. Under fluoroscopic control, the central venous catheter was slowly removed, while simultaneously contrast(More)
The different permeability of high-flux and low-flux dialysis membranes results in different removal capacity, particularly for uremic toxins of middle and large molecular weight. High-flux dialysers have been evaluated in clinical and epidemiological studies for their effect on mortality, morbidity, dialysis-related amyloidosis, nutritional status,(More)
In 15 patients with Crohn's disease a study was made of the effect of total parenteral nutrition (TPN) (nil per os) on the serum concentrations of albumin, transferrin, orosomucoid, haptoglobin, alpha 1-antitrypsin, IgG, IgA, and IgM, and on the hemoglobin concentration in blood and the erythrocyte sedimentation rate. The study covered 22 periods of TPN,(More)
Hepatic cirrhosis significantly increases the mortality and morbidity of elective surgery; therefore we hypothesized that cirrhosis would adversely impact outcome after abdominal trauma. We used the trauma registry to identify 17 patients with cirrhosis who sustained trauma injuries requiring emergent exploratory laparotomy. Patients were characterized with(More)
