Table 1

Evaluation scales used in the study and their descriptions.

Ramsay Sedation Scale (RSS) [11]

ScoreDescription
1Patient is anxious and agitated or restless or both.
2Patient is cooperative, oriented, and tranquil.
3Patient responds to command only.
4Patient exhibits brisk response to light glabellar tap.
5Patient exhibits sluggish response to light glabellar tap
6Patient exhibits no response.

Ramsay sedation score “1” was considered as unsatisfactory and “≥2” was considered as satisfactory sedation.

Parental separation anxiety scale (PSAS) [1214]

ScoreDescription
1Child separates easily
2Child whimpers, but easily assured
3Crying and cannot or is difficult to be assured
4Crying and clinging to parents

A score of 1-2 was considered “satisfactory separation” and a score of 3-4 was considered “unsatisfactory separation.”

Mask acceptance scale (MAS) [14, 15]

ScoreDescription
1Unafraid, cooperative, accepting mask readily
2Slight fear of mask, easily reassured
3Moderate fear of mask
4Terrified, crying, or combative

A score of 1-2 was considered “satisfactory” and a score of 3-4 was considered “unsatisfactory”

Pediatric emergence delirium scale (PAEDS) [16, 17].

(1) The child makes eye contact with the caregiver
(2) The child’s actions are purposeful
(3) The child is aware of his or her surroundings
(4) The child is restless
(5) The child is inconsolable

Items 1, 2, and 3 are reversely scored as follows: 4 = not at all, 3 = just a little, 2 = quite a bit, 1 = very much, and 0 = extremely. Items 4 and 5 are scored as follows: 0 = not at all, 1 = just a little, 2 = quite a bit, 3 = very much, and 4 = extremely. The scores of each item are summed to obtain a total PAEDS score. ED increases directly with the total score. A score ≥10 was considered as presence of emergence delirium.
