A cuff inflator for tracheal tubes.

A simple automatic device to inflate the tracheal tube cuff during emergency tracheal intubation is described. It was tested in 60 patients undergoing elective surgery and found to be a useful and efficient adjunct.

Administration of drugs during cardiopulmonary bypass. An analysis of the fate of a bolus injected through different routes using radio-active technetium.

This study was conducted to determine the efficiency of delivery of drugs injected as boluses by the common routes available during cardiopulmonary bypass. Radioactive technetium (99mTc) was injected in a 50 microCi bolus into the central venous line or into the arterial or venous lines of the oxygenator and its passage monitored downstream by suitable radiation detectors. When injected into the central venous line, delivery was unpredictable and at times 50% or more of the dose may not appear for 5 min. When injected into the venous line of the oxygenator an average 5% of the total dose had not reached the detector during first passage, and had completely cleared at 2 min. No significant difference was found between the different oxygenators and it is concluded that the venous line of the oxygenator is the most efficient site for the achievement of rapid action of drugs.

Control of heparinisation during cardiopulmonary bypass. Experience with the activated clotting time method.

A rational approach to the control of heparinisation during open heart surgery is advocated. Some of the possible and potential shortcomings of the time-based heparin protocols in current use are presented. The use of a recent, simple automated device 'Hemochron' to estimate the Activated Clotting Time is described and it is found to be an economical and efficient method to monitor heparinisation during cardiopulmonary bypass.
