A STUDY ON THE CONSCIOUS SEDATIVE EFFECT OF CHLORAL HYDRATE/HYDROXYZINE WITH AND WITHOUT $N_2O-O_2$

The purpose of this study was to compare the clinical sedation effect of chloral hydrate and hydroxyzine combination with and without nitrous oxide/oxygen inhalation when young children were sedated for dental treatment. The uncooperative 20 children aged, 21 to 47 months of age(ASA Class I), participated in the study. The author examined 20 children(male 12, female 8). Each patient was assigned to receive chloral hydrate(50mg/kg) and hydroxyzine(25mg). Next appointment, each patient was assigned to receive , choral hydrate and hydroxyzine. Sleep, crying, movement, and overall behavior response were evaluated, and the sedative effects were evaluated by Houpt's rating scale. Pulse rate and peripheral oxygen saturation were also measured for monitoring the sedated patients during treatment period by pulse oximeter. The result were as follows : 1. In the evaluation of sleep scores, crying scores, and movement scores, chloral combination group was significantly rated high(p combination group was significantly rated high(p combination group and 63.3% in chloral hydrate/hydroxyzine combination group were rated good or very good. 4. There was no adverse side effect(i.e. respiratory depression) in both group.
