The compliance of three types of breathing tubing commonly used in lung ventilators was measured. The black rubber corrugated tubing commonly used in anaesthetic circuits is too compliant for use in ventilators in intensive care. It is suggested that the international draft standard of compliance for breathing tubes used in lung ventilators should be amended.
A series of 184 premedicated patients were studied to determine whether music could make the immediate waiting period before surgery more comfortable. Selected music at a known noise level was being played by a tape recorder in a waiting room with open doors within the operating department. After the operation patients were asked about their impressions. A favourable result was obtained in 96.8% of the patients, i.e. 52.2% positively satisfied, 22.3% neutral and 22.3% not noticing the music. The negative impressions were mostly emotional or perhaps due to an adverse reaction to a premedication constituent: dehydrobenzperidol. The authors recommend the use of music while you wait for surgery. (Acta anaesth. belg., 1980, 31, 61-67).
Tissue sectioning is a necessary preliminary step in the preparation of organ culture explants. The real extent of tissue damage in the "wound healing reaction" can be assessed by DNA isotopic labeling. The differential count of labeling indices between epithelial structures located at the margin of the explants and similar structures near the center was used to study the influence of tissue damage on DNA synthesis. Our results suggest a time-related influence of wound healing on labeling indices. This reaction has to be taken into account when DNA synthesis is used as an indicator of hormonedependency in vitro.
