The experiential curriculum: an alternate model for anaesthesia education

The shift to direct entry into residency training from medical school for all graduates will offer new challenges for anaesthesia training programmes. In this paper we argue that it also offers us an opportuni...

Fresh gas flow and carbon dioxide rebreathing in a low pressure semi-open anaesthesia system

We have constructed a simple system for field anaesthesia by using a Farman entrainer and a semi-open circuit to convert a draw-over apparatus to a continuous flow air/O₂ system. Compressed O₂ was the driving gas...

Anaesthesia services and the education of anaesthetists in Nepal: a model for sustainable development?

In 1985 the University of Calgary in Canada and Tribhuvan University in Kathmandu, Nepal jointly established the Diploma in Anaesthesiology (DA) programme in Nepal. To evaluate the impact of the DA Programme a...

Pressure controlled-inverse ratio ventilation and pulmonary gas exchange during lower abdominal surgery

Although pressure controlled-inverse ratio ventilation (PC-IRV) has been used successfully in the treatment of respiratory failure, it has not been applied to the treatment of respiratory dysfunction during an...

Carbon dioxide absorption and gas exchange during pelvic laparoscopy

Twelve ASA physical status I-II patients undergoing pelvic laparoscopy for infertility were enrolled in a study to quantify the effects of CO₂ insufflation and the Trendelenburg position on CO₂ elimination and pu...

Large tidal volume ventilation improves pulmonary gas exchange during lower abdominal surgery in Trendelenburg’s position

Impaired pulmonary gas exchange is a common complication of general anaesthesia. Periodic hyperinflation of the lungs and large tidal volume ventilation were the first preventive measures to be widely embraced...

Time-cycled inverse ratio ventilation does not improve gas exchange during anaesthesia

Inverse ratio ventilation (IRV) has been reported to improve oxygenation at lower peak airway pressures in patients with respiratory failure. Therefore we hypothesised that IRV might also improve oxygen exchan...

A low-pressure portable anaesthesia system for field use: clinical trials

This is a report of our experience with a portable anaesthesia system that was developed for use under field conditions, when compressed gas supplies are limited. We first assembled and bench-tested a low-pres...

Re-evaluation of the Farman entrainer in a low-pressure system for field anaesthesia

The aim of this project was to develop a portable anaesthesia system that was compatible with modern anaesthesia practice under field conditions, when compressed gas supplies are limited. We assembled and eval...

The effect of halothane anaesthesia on the asphyxiated foetal lambin utero

In a previous study, we examined the effects of halothane on the normal foetal lamb in utero. The most significant finding was a 33 per cent fall infoeial mean arterial blood pressure (MABP). Cardiac output an...
