This study presents a review of 961 patients treated in the general intensive care unit (ICU) of Akershus Central Hospital (ACH) from 1978 to 1981, including also a follow-up study of the 419 patients treated in 1978 and 1979 who were observed for an average period of 20 months after admittance to the ICU. The ICU patients represented 1.7% of all the(More)
Dog models of total brain ischaemia for the study of pathophysiological mechanisms and post-resuscitative therapy used since 1970 are reviewed. Attempts to produce isolated total cerebral ischaemia in dogs either failed to stop cerebral circulation completely because of the abundance of collateral vessels or involved complex operations with blood loss.(More)
The assumption that the respiratory system behaves with 2 df of motion in healthy persons allows calibration of respiratory inductive plethysmography (RIP) with spirometry (SP). To ascertain whether RIP could be calibrated by the same assumption in patients with lung disease, even though at least 3 df of motion are visualized (ie, upper and lower rib cage(More)
The effects of 0.5% bupivacaine 1.5, 2 and 3 ml in 8% glucose was compared in a double-blind study involving 30 patients undergoing spinal analgesia. The time to the onset of maximum segmental spread of analgesia was approximately 15 min for all three volumes. Cephalad spread of analgesia was related to the volume used: 1.5 ml reached T10, 2 ml T8 and 3 ml(More)
Cross-clamping of the ascending aorta in dogs for 15 min produced severe neurological deficit, observed for up to 20 h. Immediately after restoration of the circulation, the intracranial pressure in the cisterna magna increased transiently to a mean peak of 22.8 Torr (SD +/- 1.7) because of a compensatory increase in systemic arterial pressure, without a(More)
The aims of this study included assessment of accuracy of respiratory inductive plethysmography when pulmonary hyperinflation was induced by application of PEEP, and examination of breathing patterns of normal subjects, intubated patients requiring mechanical ventilation and intubated patients immediately before extubation during application of PEEP by(More)
