A proximal positive end-expiratory pressure (PEEP) and continuous positive airway pressure (CPAP) system was constructed by the simple addition of a venturi T-piece proximal to the exhalation limb of a breathing circuit. The level of PEEP or CPAP was determined by the amount of flow powering the venturi. This system can provide positive pressure in excess of 40 cm H2O without the need for check valves, dump valves or additional nebuliers and flowmeters.

Case Reports
Successful use of dantrolene sodium in human malignant hyperthermia syndrome: a case report.
We present a case of malignant hyperthermia in which successful management included the intravenous use of dantrolene sodium. A subsequent operation under spinal anaesthesia with oral dantrolene prophylaxis did not lead to development of malignant hyperthermia. Since this syndrome is rare during regional anaesthesia, the role of prophylactic oral dantrolene in preventing the redevelopment of malignant hyperthermia in our patient is open to question.
