The Bain anaesthetic circuit.

The Bain co-axial circuit is a recent and versatile addition to the semiclosed anaesthetic breathing systems. The relationship between the patient's arterial carbon dioxide tension (PaCO2) and fresh gas flow during intermittent positive pressure ventilation (IPPV) using this circuit has been reassessed. A mean PaCO2 of 33,4 mmHg for 64 patients was recorded using a fresh gas flow of 100 ml/kg/min and a mean PaCO2 of 37,3 mmHg for 55 patients using a fresh gas flow off 70 ml/kg/min.

The effect of diazepam and lorazepam on awareness during anaesthesia for Caesarian section.

One hundred-and-eighty-three patients having general anaesthesia for Caesarian section were given lorazepam or diazepam intravenously immediately following delivery. The incidence of unpleasant recall was comparable with the reports of other workers. There was no evidence of a specific retrograde amnesic effect by either drug. Neither agent appeared to affect cardiovascular stability, uterine contraction, the reversal of muscle relaxant or the time to recovery of protective reflexes. The patients tended to be drowsier after lorazepam but as safe as after diazepam so far as circulation, respiration and protective reflexes were concerned.

Apparatus for emergency anaesthesia outside main hospitals.

The criteria which govern the design of anaesthetic equipment for emergency use away from a sophisticated operating theatre in a base hospital is discussed. A recently developed portable anaesthetic unit based on the air draw over principle and designed particularly for use with an obstetric flying squad is described and discussed.

Tracheal dilatation.

Three cases of tracheal dilatation following prolonged ventilation through a tracheostomy tube with a conventional cuff are reported. The routine care of tracheostomies in the ITU at Northampton General Hospital is described. Possible causes for the development of dilatation are suggested and the symptoms and signs discussed.
