Study Population

From other study results, average NPi for Sevoflurane and propofol were 3.6, 4.2, and standard deviation was 0.1, 0.4 respectively. Using Gpower program, total of 18 patients were required. Considering 20% of drop-out rate, total of 22 patients(18+3.6 patients) were to be recruited.

Description

Inclusion Criteria:

  • Pediatric patients undergoing general anesthesia

Exclusion Criteria:

  • If injection of any agents that can change pupil size or index
  • Any severe side effects, adverse drug reaction
