A 5 year audit of cardiac arrests at Riyadh Armed Forces Hospital.

There were 347 cardiac arrests analysed over a 5 year period. 180 patients were successfully resuscitated and 61 eventually left hospital. Patients with thromboembolic disease, renal failure, stroke, neoplasia, head injury and septicemia did badly. No patient with liver failure who arrested left hospital. The need for intubation at the arrest was associated with an increased mortality. Patients who developed ventricular fibrillation or tachycardia were more likely to survive than patients who developed asystole. Our discharge outcome of 18% compares favourably with all previous studies.

Extracorporeal shock-wave lithotripsy (ESWL)-induced erosions in upper gastrointestinal tract. Prospective study in 40 patients.

In a prospective study in 40 patients receiving ESWL treatment, gastric and/or duodenal erosions occurred in 32 patients (80%); in 24 (60%) the erosions were in the proximal part of the stomach. There was no direct relation between the patients' weight and the development of erosions. In some patients more erosions developed in relation to the number of shock waves received and the intensity of energy given. In most patients early onset of hematuria indicated development of more erosions. To our knowledge this is the first report in the literature on ESWL-induced erosions in the upper gastrointestinal tract.

How much is Jack worth? A study of the work of anaesthetists' in the S.E. Thames Region.

A study of anaesthetists' work in the S.E. Thames Region has indicated that about three-quarters of actual working time is spent giving anaesthetics, the rest of the time being spent on activities outside the operating theatre. In addition, however, equal amounts of time to that spent working is committed to being on call, so that the average total amount of time committed to the N.H.S. by the four grades of staff studied is 75.8 hours. While current maximum salary scales may (arguably) bear a resonable relationship to a 38.5 hour week, calculations of remuneration based on the data elicited from the study in respect of the amount of time actually committed and equivalent rates paid to junior staff or doctors in Europe suggest a considerable shortfall in consultant remuneration.

Myocardial stimulation by pancuronium bromide.

The effect of pancuronium bromide on the canine myocardium was studied by observing several indices of myocardial contractility during i.v. and intracoronary infusion of the drug in an anaesthetized, open-chested dog preparation. Pancuronium produced tachycardia when given for 2 min by i.v. and intracoronary infusion with the heart intact. Following denervation and pacing of the heart the intracoronary infusion of the drug produced increases in maximum acceleration of blood at the aortic root, peak aortic blood flow, maximum dP/dt and (maximum dP/dt)/TP. These changes occurred about 30 s after starting the infusion and returned to control values 5 min after stopping the infusion.

A ventilation monitor during demand flow CPAP.

A commercially available pressure alarm monitor has been suitably modifed to provide audible warning of significant and critical changes in the respiratory patterns during demand flow spontaneous ventilation with CPAP. The alarm retains its originally intended function, i.e. detection of ventilation failure during controlled or assisted ventilation or both, with or without PEPP.

A new versatile breathing system for CPPB. The application of PEPP during assisted and controlled ventilation or demand flow CPAP during spontaneous ventilation, with or without IMV.

A system is described which has been designed to improve the management of patients requiring CPPB. It makes use of a modified Bird Mark 7 or 8 ventilator adapted with a PEPP compensator and a new breathing circuit. This versatile unit provides several advantages over other currently available systems and makes it possible to apply PEPP during controlled and/or assisted ventilation as well as CPAP during spontaneous respiration, with IMV if another servo ventilator is included. This system has been in clinical use for 2 years and has proved to be highly reliable and efficient in both adults and children.

Anaesthetic records in Great Britain and Ireland.

A survey of anaesthetists and their use of anaesthetic records was carried out in Great Britain and Ireland. An analysis of 206 different record sheets from 175 hospitals or groups showed that, although many features were similar, important aspects were omitted in some, while others had too many options which were not necessarily relevant to the administration of an anaesthetic. No attempt has been made to offer an ideal design for an anaesthetic record, but the information may assist those anaesthetists wishing to change the current practice in their hospital or group.
