Many research-based models of information seeking behaviour are limited in their ability to describe everyday life information seeking. Such models tend to focus on active information seeking, to the neglect of less-directed practices. Models are often based on studies of scholars or professionals, and many have been developed using a cognitive approach to(More)
Forty patients with fractured neck of femur were allocated randomly to undergo surgery under general anaesthesia (GA) or subarachnoid anaesthesia (SAB). After operation, the incidence of deep vein thrombosis (DVT), assessed by venography, was found to be 40% in the SAB group, which was significantly lower than the incidence (76.2%) in the GA group. These(More)
We have studied the severity and duration of nocturnal hypoxaemia before operation and for the first five nights after operation after elective major abdominal vascular surgery. Oxygen supplementation was almost 100% effective in keeping oxygen saturation greater than 90% during the early postoperative period; however, 50% of patients spent prolonged(More)
One hundred and forty-eight patients undergoing "pin-and-plate" repair of fractured neck of femur received either subarachnoid blockade or general anaesthesia. The patients were followed up for 1 year after surgery. At the end of the year, 34% had died and 50% had returned home. Twelve per cent were either in hospital or in institutional care; 4% were lost(More)
One hundred patients presenting for surgical treatment of fractured neck of femur were allocated to receive either spinal (SAB) or general (GA) anaesthesia. Before operation, the mean PaO2 was 9.04 kPa. There was a significant decrease in PaO2 of 0.68 kPa in GA group at 1 h after operation, while blood-gas values were unchanged in SAB group. Eight patients(More)
One hundred and fifty-two patients undergoing surgery for fractured neck of femur were randomly allocated to receive either general anesthesia with spontaneous ventilation with nitrous oxide and halothane in oxygen or general anaesthesia with controlled ventilation with fentanyl, nitrous oxide and halothane in oxygen. Atracurium was used to provide muscle(More)
