Sleep apnoea in babies born after in vitro fertilization.
UNLABELLED: Babies born after in vitro fertilisation (IVF) are increasing in number, and, although these babies are considered as very precious, no data are available regarding their risk for sudden infant death or apnoea. To evaluate the respiratory maturity of IVF babies, we evaluated the incidence of apnoea during an 8-h polysomnography in 50 consecutively presented IVF babies and in a group of 50 unselected naturally conceived babies. All infants were in good health and matched for term (born > 38 weeks of gestation), birth weight, sex and age at the time of investigation (6-11 weeks post term, median 8.0). There were 24 twins in the IVF and 6 twins in the control group. The incidence of obstructive and isolated central apnoea was comparable in the IVF and control group. However, IVF babies had significantly more periodic breathing episodes than control babies (median 2.30 (range 0-15.30) in IVF, and 1.02 (range 0-11.2) in control babies; P < 0.01). This difference was not related to the higher number of twins in the IVF group. Single IVF babies had significantly more short central apnoeas (5-10 s) than IVF twins (5-10 s) (mean 38.80 +/- 18.63 and 22.33 +/- 13.35; P < 0.001). This difference between single and twin babies was not found in the control group. CONCLUSION: IVF babies have more periodic breathing episodes indicating an immature respiratory pattern than normally conceived babies.
Dehydrobenzperidol as peroperative anti-emetic: most effective administration time.
206 female patients undergoing curettage or laparoscopy were randomized in 4 comparable groups. Group 1 did not receive dehydrobenzperidol (DHBP), group 2 was given DHBP during premedication, group 3 during induction of anesthesia and group 4 when patients presented symptoms of nausea and/or vomiting. Again, the statistical results confirm the strongly anti-emetic effects of DHBP. Because of the existing trend towards a more beneficial effect of DHBP if given during induction and the avoidance of a possible adverse reaction, administration during induction is to be preferred, at least in non-ambulatory patients.

Can inhaled anesthetics influence the breath analyser Alcotest?
An in vitro study was made to verify whether anesthetic vapours, exhaled after anesthesia can influence the breath analyser test used in Belgium by the prosecuting authorities. Of the exhaled anesthetic vapours halothane, enflurane, methoxyflurane and diethyl ether, only diethyl ether will be able to produce a positive breath test.

Music while you wait. Patient acceptance of music in the preanesthetic period.
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).
