Randomized Controlled Trial Clinical Trial
Assessing the position of the tracheal tube. The reliability of different methods.
Various methods have been developed to confirm proper intubation of the trachea. This blind, randomised study evaluates some of these quantitatively and qualitatively. Forty patients had both their trachea and oesophagus intubated. ⋯ Auscultation of the lungs resulted in a wrong conclusion in 15% (6-30, 95% confidence limits) of the cases when the oesophagus was ventilated: the sounds were misinterpretated as normal breath sounds. Suction on the tubes with a 60-ml syringe was also a reliable test. Other methods assessed were observation for condensation of water vapor, and abnormal movements of the upper abdomen; these were unreliable.

Randomized Controlled Trial Clinical Trial
Pain relief after tonsillectomy. Effect of benzydamine hydrochloride spray on postoperative pain relief after tonsillectomy.
The efficacy of benzydamine hydrochloride (Difflam) spray to relieve pain from postoperative tonsillectomy was assessed, but it was found that it did not relieve the symptoms after operation when compared to matching placebo.

Fifty-three patients were admitted in a 5-year period to the intensive care unit as a result of a complication of an anaesthetic technique. These patients represented 1 in 1543 anaesthetics carried out in the District in the period and 2.0% of all admissions to the intensive care unit. ⋯ The complication was considered to be wholly or partially avoidable in 14 instances (26%). Five of these subjects died and two had a residual neurological deficit.

There are no published comprehensive surveys of paediatric recovery room experience and the incidence of complications. A prospective survey was made of 16,700 consecutive admissions to the recovery room at the Royal Manchester Children's Hospital during the years 1985-1988. The incidence of respiratory complications was low, with laryngospasm 0.85%. ⋯ The incidence of vomiting in the recovery room was also lower than in comparable adult studies. Certain aspects of recovery room practice changed during the 4 years of the study; these included routine oxygen administration, parents in the recovery room, and our approach to postoperative analgesia. The implications of these changes are discussed.

The tracheas of 420 adult patients were intubated using the tip of a lighted stylet placed inside the lumen of the tracheal tube, just proximal to the tube cuff. The maximum point of transillumination was visible just distal to the cricoid cartilage, with proper cuff positioning. The lighted stylet was also introduced into the oesophagus to see whether transoesophageal illumination could be demonstrated. ⋯ Transoesophageal illumination could not be demonstrated in any patient. The mean distance between the tip of the tracheal tube and the carina varied between 3.7 and 4 cm. Transtracheal illumination is a simple, effective and reliable method that can be used during intubation for the recognition of optimal tube placement.
