[Effect of oxytocin on postoperative intestinal atonia after open cholecystectomy].

A double-blind trial was undertaken to assess the effect of oxytocin on the duration of intestinal atony after cholecystectomy. Eleven pairs of patients were either given injections of oxytocin or placebo at regular intervals during the first and second postoperative day. Sequential analysis showed placebo as being more effective, regarding the time until flatus was passed.

[Bone scintigraphy in assessment of risk of complications after medial femoral neck fractures].

The value of visually evaluated bone scintigraphy in predicting postoperative non-union and avascular necrosis was examined in a prospective, consecutive series of patients with intracapsular fracture of the femoral neck. 49 patients had scintigraphy carried out preoperatively, and 37 postoperatively. In 18 scintigraphy was done preoperatively as well as postoperatively.

Prediction of late complications of femoral neck fractures by scintigraphy.

A prospective study was undertaken to determine the value of scintigraphy in predicting nonunion or necrosis of the femoral head following femoral neck fractures. Scintigraphy was carried out in 49 patients before operation and in 37 one week after operation; in 18 it was done before and after operation. The uptake of isotope was estimated visually as either normal or reduced compared to the opposite side.

Increased hepatic amino nitrogen conversion after elective cholecystectomy in man.

1. The effect of elective, uncomplicated cholecystectomy on plasma clearances of amino acids and on amino acid-stimulated urea synthesis was investigated in 10 patients, pre-operatively and on the first post-operative day, and compared with six controls treated identically apart from the surgery. 2.
