This study compares some physical characteristics of a selection of cuffed endotracheal tubes with large-volume, low-pressure cuffs currently used in the United Kingdom. Six types of endotracheal tubes of Sizes 7, 8 and 9 were studied. There was considerable variation in physical characteristics of endotracheal tubes and cuffs from different manufacturers and even from the same manufacturer.

Randomized Controlled Trial Clinical Trial Controlled Clinical Trial
The oesophageal detector device. A prospective trial on 100 patients.
Misplacement of a tracheal tube in the oesophagus remains a significant cause of mortality and morbidity in anaesthesia, despite decades of effort aimed at prevention, or perhaps more importantly, detection, of such an event. We have evaluated a cheap, simple and quick device which relies mainly on the reflation or otherwise of an Ellick's evacuator applied to the supposed 'tracheal' tube. ⋯ There were no false positive results and the correct deduction of which was the tracheal tube was reached in 100 tests using this device. Its use is recommended for widespread evaluation as a valuable adjunct to existing methods of detecting misplacement.

Digital nasotracheal intubation may be useful in situations where blind nasotracheal intubation is unsuccessful. This technique can be performed in edentulous patients and may prove to be a valuable adjunct in controlling the airway.

Randomized Controlled Trial Clinical Trial
Effect of buprenorphine on the cardiovascular response to tracheal intubation.
The effects of buprenorphine on the haemodynamic responses to tracheal intubation were studied in a placebo-controlled double-blind trial in 40 patients who had elective surgery. In one group saline was administered intravenously 8 minutes before induction, whereas the others received buprenorphine 2.5 micrograms/kg intravenously. ⋯ In the buprenorphine group, the maximum increase in systolic and diastolic arterial blood pressures, heart rate and rate pressure product were significantly lower compared to the control group. It is concluded that buprenorphine is partially effective in attenuating the cardiovascular response to laryngoscopy and intubation, but does not obliterate it.

A newly designed nasal bridle and rationale for its clinical use are described. Previous nasal bridles have been shown to reduce the 40 to 60% incidence of dislodgement of nasoenteral feeding tubes. ⋯ The newly designed nasal bridle described herein has the advantages of easy and rapid placement. Use of this bridle can promote safer and more effective enteral feeding while avoiding the complications and cost of parenteral nutritional and gastrostomies.
