چکیده
profound bradycardia during eye surgery is a potentially serious event. in clinical practice oculo-cardiac reflex (ocr) is most often encountered during squint surgery. the objective of this study was to assess the occurrence of ocr and prove the effect of ketamine as an induction drug and anticholinergic premedication (atropine) to prevent ocr. this study comprised 90 patients (aged 4-10 years) operated for squint surgery under general anesthesia. patients were divided into three groups. using block randomization, each patient enrolled in one of the three groups based on organized random table prepared by statistician. group k received ketamine as an induction drug, group a was premedicated with intravenous injection of atropine and group c did not receive any premedication. patients were monitored during operation for any bradycardia or dysrhythmias. the observed data showed occurrence of 63% ocr in group c as compared to 43% in group a and only 20% in group k. current study showed that induction with ketamine in the patients of squint surgery under general anesthesia definitely obtunds ocr and prevents any untoward effects of dysrhythmias during eye surgery.
