The Effect of Preoperative Ketamine on the Emergence Characteristics in Children Undergoing Entropion Surgery

The Effect of Preoperative Ketamine on the Emergence Characteristics After Desflurane or Sevoflurane Anesthesia in Children Undergoing Entropion Surgery

The investigators evaluate extubation time and recovery profiles in children undergoing entropion surgery.

This study will compare the extubation time and recovery profiles (degree of postoperative agitation and cough) between sevoflurane group and desflurane group. General anesthesia will maintained with sevoflurane 2-3vol% or desflurane 6-7vol%. After surgery, the investigators will measure the duration of extubation and recovery profiles between two groups.

Inclusion Criteria:

• American society of anesthesiologist class 1 patients
• 3-6 years children undergoing entropion surgery

Exclusion Criteria:
