RESUMO
In 20 adult patients (18 male) who presented for thoracotomy, the trachea was intubated using Mallinckrodt disposable double-lumen tubes (18 large and two medium). The endobronchial cuff was inflated by a trained operating department assistant using an air-filled syringe. The volume of air and the initial endobronchial cuff pressure were measured. The minimum cuff pressure required to prevent respiratory gas leakage from the isolated lung was measured also and maintained using the Cardiff Cuff Controller. Mean initial cuff pressure was 69.3 (SEM 6.0) mm Hg, whereas the mean minimum cuff pressure was 29.5 (4.0) mm Hg (P < 0.0001). The results suggest that the method described of inflating the endobronchial cuff may lead to overinflation and subsequent excessive pressure on the endobronchial wall.

One hundred and twenty-four patients (76 women and 48 men) were interviewed within the first 36 hours after operation. Fifty per cent of those studied were denture wearers. They were asked to fill in a questionnaire which registered their levels of distress about the various pre-operative preparation procedures. The most common factors contributing to pre-operative distress were waiting for transfer to the operating theatre, the prohibition of fluids and the removal of dentures.

The extent of airborne environmental bacterial contamination which occurs following tracheal suction has been investigated in patients undergoing intermittent positive pressure ventilation in the intensive therapy unit. Two methods of performing suction, one using a conventional open technique and one using a closed system (Stericath), have been compared. Significantly lower levels of environmental contamination were observed when the closed system was used.

In recent years endotracheal tubes with low pressure cuffs have become available with the aim of reducing trauma to the trachea and larynx. This paper uses laryngographic methods to analyse intubation trauma in 20 short to medium term intubations. No difference in laryngeal trauma was found between low pressure, large diameter cuffs when compared to standard cuffs.
