[Local reactions following intravenous injection of Valium mixed micelles and Diazemuls].

The frequency of local venous reactions after intravenous injection of Diazemuls and Valium Mixed Micelles was studied. A material of 224 patients undergoing surgery for prolapsed lumbar disc was allocated into two groups, receiving either 10 mg of Diazemuls or Valium Mixed Micelles. The incidences of thrombophlebitis in the two groups were 1 and 2%, respectively.

Carbon dioxide tensions in manually ventilated, prone patients.

The distribution of arterial carbon dioxide tensions (PaCO2) in 288 anaesthetized, healthy patients in the prone position was investigated during non-monitored manual ventilation. Four equal groups of 72 patients were compared employing a conventional anaesthetic system with and without CO2-absorption and a modified Mapleson D rebreathing system using high and low fresh gas flows. No fundamental difference between the Mapleson D system and the circle system without CO2-absorption could be demonstrated. With the Mapleson D system a high fresh gas flow resulted in a loss of rebreathing characteristics, the scatter of PaCO2-values then approaching that of a conventional circle system with CO2-absorption. The results demonstrate that during manual ventilation a CO2-absorption results in unpredictable levels of PaCO2 with unacceptably wide ranges. On the other hand, prevention of hypocapnia could be obtained with the rebreathing systems using a low fresh gas flow. Hypercapnia was modest and similar in all groups, PaCO2 never exceeding 7.3 kPa. In terms of PaCO2-levels it seems, compared to recent literature, of no importance whether the patient is prone or supine or whether or not ventilation is monitored, performed by hand or by means of anaesthetic ventilators. Accurate levels of PaCO2 can probably only be obtained by frequent analyses of PaCO2, or monitoring of the end-tidal CO2 concentration.

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.

Althesin in neurosurgical patients: effects on cerebral hemodynamics and metabolism.

The effect of althesin 0.5 ml/10 kg on arterial blood pressure, intracranial pressure, cerebral blood flow and oxygen uptake was studied on 19 occasions in 16 patients with varied cerebral pathology. Cerebral blood flow (CBF) was measured using the intracarotid 133xenon method and a 35-channel scintillation detector after cannulation of the internal carotid artery, the internal jugular bulb and the lateral cerebral ventricle. Arterial and intracranial pressures were recorded continuously. Blood gas tensions were measured in simultaneously drawn samples from the internal carotid artery and the jugular bulb. Cerebral oxygen uptake was calculated from the product of CBF and arteriovenous oxygen content difference. Control values were obtained with the patients under a basic general anesthesia, consisting of N2O/O2 pancuronium. The effect of a bolus injection of althesin was then studied 1 and 20 min after the injection. A significant reduction in intracranial pressure, cerebral blood flow and metabolism at 1 min was found to have essentially subsided 20 min after the injection. In patients with focal brain damage, regional flow analysis revealed a paradoxical increase in flow after althesin in the areas corresponding to the focus.
