An electronic high-pressure alarm for detecting obstruction of the fresh gas flow line in T-piece type anaesthetic circuits is described. The system is small, battery operated, and unobtrusive on the anaesthetic machine. The alarm is designed to sound whenever an obstruction reduces fresh gas flow to the patient, resulting in undesired rebreathing of expired gases.
Anaesthesia for the separation of conjoined twins requires a multi-disciplinary team approach. We describe the anaesthetic management of a single-stage separation of 2 1/2-year-old omphalo-ischiopagus tripus conjoined twins. The successful 17 1/2-hour operation was conducted by five anaesthetists and 38 surgeons and nurses. Two major problems were encountered: massive blood loss in both twins (requiring transfusions of more than five and seven times their blood volumes) and a transient decrease in core temperatures after separation.

Homologous blood transfusions are not without risks, especially in young women and girls. In patients undergoing certain elective surgical procedures autologous blood transfusion is a good alternative. Normovolaemic haemodilution in association with autotransfusion offers the additional advantages of reduced loss of red cell mass during the operation and an increase in tissue blood flow. In this study twenty-seven adolescent patients undergoing Harrington instrumentation for idiopathic scoliosis had haemodilutional autotransfusions during their operations, none requiring homologous blood. Eighteen were given an average of 750 millilitres of homologous blood in the postoperative period which compared favourably with controls who required 1280 millilitres.
