A case report of surgical repair of traumatic rupture of the pericardium and diaphragm

A 55 year-old male with traumatic rupture of the pericardium, diaphragm and spleen, and with crush of the pancreas was successfully operated upon. The diagnosis of rupture of the diaphragm was done on the chest X ray on admission, and the rupture of the pericardium was diagnosed at the time of laparotomy and thoractomy. The ruptured spleen and the crushed pancreas tail were removed, and the ruptured peridardium and diaphragm were closed successively.

Comparative study on the influences of plasma substitutes on the blood coagulation

Comparative study on the influence of plasma substitutes, dextran, hydroxyethyl starch and gelatin derivative solution, on the blood coagulation was carried out in dogs with thrombelastogram.It was demonstrated that plasma substitutes caused a remarkable suppression of the coagulation system inducing qualititative and quantitative changes of the coagulation factors. However, these changes did not seem to be related to hemodynamic disorders. Much greater decrease of platelets and fibrinogen levels than that of hematocrit following hemodilution with plasma substitutes suggests that the suppression of the coagulation system observed after infusion of plasma substitutes is likely to be due to consumption.
