NCT04353960
Brief Summary:
Observation study monitoring vital signs and anesthetic variables particularly heart rate during prospective, ocular manipulation and specifically uniform tension on extra ocular muscles during strabismus surgery.
\*IRB approval from 1992 covered in letter from then IRB chair Dr. Judith Whitcomb, Anchorage, Alaska (letter 10/2020).\*
Detailed Description:
Patients with ocular manipulation including those scheduled for strabismus surgery will have peri-operative variables monitored before, during and after uniform traction on extra ocular muscles (EOM). The oculocardiac reflex (OCR) will be elicited by quantified (200 gram, 10-second, square-wave) traction on Jameson muscle hook under insertion of an extra ocular muscle (EOM, rectus). Stable pre-tension heart rate, and greatest change heart rate will be recorded. Additional variables to be recorded: birthdate, gender, race, weight, iris color, pre-operative neurodevelopmental conditions, pre-operative medications, induction medications, expired carbon dioxide (CO2) levels, exhaled gas concentrations, anticholinergic medications, opioids, muscle relaxants, type of airway and the number of EOM operated.
