Background: Strabismus correction surgery is the most common eye operation in children. The present study aims to evaluate the effects of Oro Tracheal Intubation (OTE) using a neuromuscular blocking agent (NMA) in strabismus surgery anesthesia and Laryngeal Mask Airway (LMA) application using Total Intra Venous Anesthesia (TIVA) without using NMA on the deviation angles measured following strabismus surgery.
Methods: ASA I-II group patients with concomitant horizontal strabismus, aged under 14, scheduled for strabismus surgery under general anesthesia were prospectively examined for the study. The study did not include those with restrictive type strabismus, vertical deviation, intraoperative vertical muscle group treatments, anisometropia, and corrected visual acuity less than 0.8. According to the order of arrival, either OTE was conducted with NMA, or LMA (LMA-group) was utilized without NMA for general anesthesia in patients.
Results: The study included 49 patients, divided into LMA (n=24) and OTE (n=25). The patients' mean age was 8.04 ± 3, 63 years. The distribution was similar between groups, with 63% (n=31) having esotropia and 37% (n=18) having exotropia. Angles of deviation were measured to be above 10 Δ D in 1 patient in the LMA group and two patients in the OTE group at the end of postoperative 1st month. There was no statistically significant difference between the groups regarding decreased postoperative deviation angles and preoperative-postoperative deviation angle measurements.
Conclusion: The tone changes in the eye muscles using NMA’s in strabismus surgery anesthesia caused no changes in the postoperative deviation angles or the surgical result.
