Influence of general anaesthesia on portal pressure in liver cirrhosis and portal hypertension.

In 19 patients with cirrhosis of the liver and portal hypertension, a catheter was inserted into the portal vein using a percutaneous transhepatic technique. The portal pressure was measured during general anaesthesia with and without halothane, and in the awake state. Addition of halothane to the N2O:O2 anaesthesia did not change portal venous pressure, in spite of a significant fall in arterial blood pressure. Portal venous pressure under general anaesthesia with complete muscle relaxation did not differ from the pressure in the resting, awake patient.

The postanesthetic antiemetic effect of premedication with dehydrobenzperidol before ether anesthesia.

A study was performed to evaluate the antiemetic effects after ether anesthesia when dehydrobenzperidol (DHB) and pentobarbital were used for premedication and to compare these effects with halthane anesthesia when pentobarbital was used as premedication. Eighty-four patients undergoing minor surgical operations were randomly divided into three groups. The patients received ether and ether DHB 0.2 mg/kg or pentobarbital 2 mg/kg for premedication, or halothane and pentobarbital 2 mg/kg for premedication. The complaints of nausea and vomiting were recorded 24 h after anesthesia. We found that DHB compared to pentobarbital had a greater antiemetic effect after ether anesthesia, but the difference was not significant (P greater than 0.05). However, if only persistent nausea and vomiting were considered, the difference was significant (P less than 0.05). The incidence of nausea/vomiting after ether anesthesia with DHB as premedication was a little higher compared to halothane anesthesia with pentobarbital as premedication, but the difference was not significant (P greater than 0.05). However, if only persistent nausea/vomiting was considered, the incidence of complaints was equal in the two groups. It is concluded that when used for premedication to ether anesthesia DHB seems to lead to less postanesthetic nausea/vomiting than pentobarbital. Further DHB seems able to reduce the incidence of nausea/vomiting after ether anesthesia roughly to the level of that seen after pentobarbital premedication for halothane anesthesia.

Effect of spinal sympathetic blockade upon local regulation of blood flow in subcutaneous tissue.

The influence of spinal sympathetic blockade upon local regulation of blood flow in subcutaneous adipose tissue was investigated in six subjects. The effect of changes in orthostatic pressure on blood flow in subcutaneous tissue in the crus and distal forearm was measured before and after sympathetic blockade obtained by epidural anesthesia in 4 subjects and by a bilateral sympathectomy in 2 patients suffering from manual hyperhidrosis. Blood flow in subcutaneous tissue measured by 133Xe washout technique decreased by about 40 per cent when the limb was lowered, and remained constant during 30 cm elevation. This was found both before and after the blockade, though in one of the patients, the orthostatic decrease in blood flow was less pronounced 24 h after sympathectomy. Hence central sympathetic reflexes do not alter local orthostatic changes of blood flow in subcutaneous tissue. These changes therefore are most likely due to local mechanisms.
