Comparative StudyAirway lesions caused by prolonged intubation with standard and with anatomically shaped tracheal tubes. A post-mortem study.
Two groups of patients intubated for long periods were examined post mortem. In Group A (22 patients) the mean duration of intubation was 4.0 days and in Group B (19 patients) 5.7 days. The mean for the two groups was 4.8 days. ⋯ The photographs were magnified and from these the size and estimated depth of any lesions were recorded. In the arytenoid and tracheal regions no significant difference was found between the two groups. In the cricoid region, on the other hand, the outcome was significantly more favourable following use of the anatomically shaped tube.

Randomized Controlled Trial Comparative Study Clinical TrialHemodynamic effects of atracurium, vecuronium and pancuronium during sufentanil anesthesia for coronary artery bypass.
A study was undertaken to evaluate the cardiovascular effects of sufentanil, in combination with three different muscle relaxants, used as sole anesthetic with 100% O2 in 30 patients undergoing elective coronary artery vein graft surgery. Patients were randomly allocated to receive pancuronium (P), vecuronium (V) or atracurium (A) for muscle relaxation. All patients received 15 micrograms/kg sufentanil at induction followed by 5-10 micrograms/kg sufentanil prior to sternotomy. ⋯ Sufentanil in combination with pancuronium or vecuronium provided stable hemodynamic conditions throughout anesthesia. Atracurium was less satisfactory. We conclude that there is no advantage to be gained, in the presence of beta blockade, from the use of the new generation muscle relaxants as compared to pancuronium during high-dose sufentanil anesthesia for coronary artery vein grafting.

Comparative StudyGastric volume and pH in children for emergency surgery.
The volume and pH of gastric contents aspirated prior to anaesthesia were measured in 101 children admitted for emergency surgery. The children were aged between 3 months and 15 years. If we define potential patients at risk by means of the volume and pH of the gastric contents, then 50.0% of the children were at risk of aspiration into the lungs. ⋯ It is concluded that in children admitted for emergency surgery there is a risk of aspiration of gastric contents into the lungs. The risk is reduced by preanaesthetic fasting. All children admitted for emergency surgery must be carefully evaluated prior to anaesthesia with special reference to gastric aspiration.

Case ReportsSudden bilateral hearing loss after spinal anaesthesia. A case report.
A case of bilateral hearing loss following an otherwise uncomplicated spinal anaesthesia with bupivacaine is presented. It is suggested that a drop in intracranial pressure played a principal role in the development of this complication. Unless specifically sought for, minor auditory losses following spinal anaesthesia may be overlooked.
