The aim of this paper is to investigate a method which may decrease the incidence and severity of oculocardiac reflex (OCR) without drugs.One hundred and sixty children undergoing strabismus surgery were allocated to two groups using double-blind randomization.OCR was defined as a decrease of more than 10% from the baseline heart rate during operation.An alarm sounded and a lamp flashed as soon as OCR occurred in group Ⅰ,and neither of the above happened in group Ⅱ.OCR occurred (1.151±0.858) times in group Ⅰ and (2.287±1.371) times in group Ⅱ(P＜0.05).Heart rate decreased by (23±19) bpm in group Ⅰ and (35±28)bpm in group Ⅱ (P＜0.05).The duration of OCR in group Ⅰ and group Ⅱ was (4.36±4.26)s and (7.62±6.41)s,respectively (P＜ 0.05).The recovery time for group Ⅰ and group Ⅱ was (15.36±13.28)s and (32.36±19.57)s,respectively (P＜0.05).The numbers of times of interruption were 8 in group Ⅰ (10%) and 26 in group Ⅱ(32%) (P＜0.01).This method significantly decreased the incidence and severity of OCR during strabismus surgery in children.
