Primary hemostasis, the formation of a platelet plug, was studied in 22 injured patients receiving an average of 21 transfusions during the operation for control of bleeding. The storage age of the blood averaged 15 days; no platelet transfusions were given. Platelet counts (PLT) and bleeding time (BT) were studied intraoperatively; postoperatively at 6 hours, 25 hours, day 2, day 4; and during convalescence (8 days to 3 months). ⋯ The BT remained elevated at 6 hours, 15 hours, day 2, and day 4, and declined to normal by convalescence. Thrombocytopenia and prolonged BT after massive transfusion for injury indicate platelet dysfunction which may protect against disseminated intravascular coagulation. Correction of the thrombocytopenia should be reserved for patients with bleeding.

Case ReportsCholangiographic demonstration of relief of narcotic-induced spasm of the sphincter of Oddi.
Narcotics are known to cause spasm of the sphincter of Oddi. This spasm may be difficult to distinguish from obstruction of the distal common bile duct on operative cholangiograms in cases where narcotics are used perioperatively. A case is presented in which narcotic-induced spasm of the sphincter of Oddi, clearly demonstrated in an operative cholangiogram, is reversed by a narcotic antagonist, thereby avoiding an unnecessary common duct exploration.

Case ReportsMassive subcutaneous emphysema: an unusual presentation of jejunal perforation.
Massive diffuse subcutaneous emphysema resulting from perforation of the proximal jejunum is presented. Seventy-nine reported instances of subcutaneous emphysema of gastrointestinal origin were reviewed. Emphysema originating from the jejunum has not been previously reported. ⋯ The pathogenesis of emphysema in the patient described, as well as in the great majority of other patients, is from intraluminal gas rather than from gas-forming organisms. The air spreads along neurovascular bundles and other anatomic planes and may rapidly reach areas distant from the perforation. The recognition of these phenomena in the diagnosis of gastrointestinal perforation is important.
