Prevention of fire hazards associated with use of carbon dioxide lasers.

In vitro experiments were performed to test the flammability of endotracheal tubes in the presence of CO2 laser beams Two types of tubes (Rusch and Portex) were exposed to laser beams at 15 or 30 W intensity for varying periods of time oxygen environments of 25% or 60%. Red rubber Rusch tubes were significantly (p less than 0.01) more resistant to ignition than plastic Portex tubes at both higher energy exposures and greater durations of exposure. Aluminum tape wrapping significantly (p less than 0.01) retarded ignition of both types of tubes. In view of this, a clinical protocol was developed using aluminum tape-wrapped red rubber tubes in 98 patients for 189 procedures requiring the use of a laser. In no case was ignition encountered.

Blood transfusion--a review of the literature.

The dangers of using whole blood and its disadvantages are pointed out and the place of crystalloid or colloid transfusion as an adjuvant or substitute is discussed. The use of blood fractions for treatment of anaemias and clotting disorders is stressed. This means a reduction in amount of blood used for transfusion and hence reduction in cost and morbidity due to blood transfusion.
