Kim SH, et al. - Authors ascertained if an infratrochlear nerve block (ITB) could reduce the oculocardiac reflex (OCR) during strabismus surgery on the medial rectus muscle (MR). During surgery on the MR, an ITB was seen to maintain a stable heart rate (HR) and reduce the OCR. Findings suggested that the ITB could help improve the safety of strabismus surgery as it was seen to be less invasive and easily accessible to a surgeon. In patient demographics or baseline HR, there were no intergroup differences. Compared to the control group during muscle dissection and traction, the HR was higher and the OCR incidence was lower in the ITB group.
