Strabismus Clinical Trial
Official title:
Propofol Versus Sevoflurane Anesthesia in Pediatric Strabismus Surgery: Feasibility of BIS Monitoring
This study is conducted to evaluate importance of bispectral index (BIS) monitoring in patients undergoing strabismus surgery when using propofol in comparison to sevoflurane anesthesia regarding their effects on oculocardiac reflex, intraoperative hemodynamic stability, emergence agitation, postoperative pain, nausea and vomiting.
Strabismus surgery can cause unfavorable side effects during intraoperative and postoperative periods including increased risk of the oculocardiac reflex, hemodynamic instability, emergence agitation, postoperative pain, nausea and vomiting. Sevoflurane is an inhalation anesthetic widely used in pediatric anesthesia with minimal airway irritation. Propofol is an intravenous sedative-hypnotic agent with amnestic properties that causes loss of consciousness. Bispectral index monitor provide some more evidence that deeper anesthesia can provide some protection against the oculocardiac reflex. Therefore, this study is conducted to evaluate the role of BIS monitoring in comparing the use of propofol and sevoflurane anesthesia in pediatric strabismus surgery. This prospective, randomized, comparative clinical study will include 100 children who are scheduled for elective strabismus surgery under general anesthesia in Mansoura ophthalmology center. Informed written consent is obtained from parents of all subjects in the study after ensuring confidentiality. The study protocol is explained to parents of all patients in the study who are kept fasting prior to surgery. Patients are randomly assigned to two equal groups according to computer-generated table of random numbers using the permuted block randomization method. The collected data are coded, processed, and analyzed using SPSS program. All data are considered statistically significant if P value is ≤ 0.05. ;
