Penehyclidine reduced the incidence and severity of OCR during strabismus surgery. a The incidence of OCR in each group. b The requirement for atropine rescue in patients with OCR. c The maximum decrease of heart rate during OCR. **P < 0.01 and *P < 0.05 analyzed by Fisher’s exact test (a, b) or by unpaired student t-test (c). The numbers of patients are shown in the figures. The maximum decreases of heart rate are shown as means ± standard deviation. OCR, oculocardiac reflex; bpm, beats per minute
