This observational study monitors vital signs, especially heart rate, during eye muscle manipulation in patients undergoing strabismus surgery. It focuses on the oculocardiac reflex, which is the heart rate change caused by steady tension on the eye muscles. The study includes patients of various ages and backgrounds to better understand how this reflex occurs during surgery. Participants will have detailed monitoring before, during, and after uniform traction is applied to an extra ocular muscle using a precise 200 gram, 10-second tension method. Two groups are observed: those who receive anticholinergic medication before surgery and those who do not. The study uses an electrocardiograph to record heart activity and collect information on multiple factors like medications, airway type, and patient characteristics. During the study, researchers will record heart rate changes, anesthetic interventions, and surgeon actions. They will gather data such as birthdate, gender, race, weight, iris color, and medical history related to neurodevelopment and medications. The main outcome measured is the percentage heart rate change caused by the oculocardiac reflex within 30 seconds. Secondary outcomes include monitoring anesthetic and surgical interventions over two hours. Participants may be followed up as needed, with the study lasting until 2035.
