Adjustable Strabismus Surgery under Intravenous Anesthesia with Propofol and Fentanyl

PURPOSE: To evaluate the clinical usefulness of intravenous propofol and fentanyl anesthesia during adjustable strabismus surgery, to investigate the effectiveness and safety of adjustable strabismus surgery, and assess the degree of patient satisfaction. METHODS: Patients over 15 years of age who underwent strabismus surgery using propofol and fentanyl sedation from January 2003 to December 2004 were included in this study. At the beginning of the operation, the patients received an intravenous bolus of fentanyl 1 to 1.5 mg/kg. Propofol was injected into a vein continuously during the operation to keep the blood concentration within 1.2-1.5 ug/mL. Intraoperative adjustment was then made. We evaluated, via questionnaire, patient satisfaction with the operation and the adjustment. RESULTS: In all 44 patients, the adjustment was completed successfully. The rate of intraoperative side effects was low (11.4%). The satisfaction degree regarding the anesthesia was very high (95.5%), and the success rate at the three-month postoperative visit was 88.6%. CONCLUSIONS: Intravenous anesthesia using propofol combined with fentanyl provides a sufficient level of sedation and rapid awakening that enables a surgeon to perform adjustable strabismus surgery conveniently. It also allows the patient to feel comfortable and safe throughout the surgery.

Intraoperative Adjustment with Topical Anesthetics in Strabismus Surgery

For the better correction of strabismus surgery, various adjustable surgical technics are performed with general or retrobulbar anesthesia. Topical anesthetics with IV analgesics (Fentany 1 citrate) and sedative (Valium) can induce adequate pain control without inhibiting extraocular muscle activities and enable intraoperative adjustment easily and conveniently without the troublesome maneuver of postoperative adjustment and accompanying risk of infection Intraoperative adjustable surgery is better than postoperative adjustable surgery because it is easier to perform due to less tissue edema, enables to avoid the risk of retrobulbar or peribulbar anesthesia, and the risk of infection. We operated 20 strabismic patients aging 10 to 48 years using the intraoperative adjustment and topical anesthetics with the good success rate 90%, within +/- 10 delta after 5 weeks follow-up.
