Propofol Versus Sevoflurane Anesthesia in Pediatric Strabismus Surgery: Feasibility of BIS Monitoring

Bispectral Index (BIS) sensor electrodes are applied over the patient's forehead after cleaning the forehead thoroughly with an alcohol swab.

Capnography connected to laryngeal mask airway is introduced after adequate jaw relaxation and oral airway tolerance; its size is chosen according to the body weight of the child.

Anesthesia is induced inhalationally by face mask with 8% sevoflurane in 100% oxygen, then decreased to 2-3% in 40% oxygen thoroughout the operation for maintenance of anesthesia.

Anesthesia is induced by propofol (2mg/kg), then maintained using an infusion of fixed concentration (10-15 mg/kg/h) as titrated by the anesthesiologist .
