Trial Outcomes & Findings for Psychological Influences on Postoperative Recovery (NCT NCT00581139)

NCT ID: NCT00581139

Last Updated: 2023-09-07

Results Overview

The Modified Yale Preoperative Anxiety Scale (mYPAS) is the current "criterion standard" for assessing child anxiety during induction of anesthesia and has been used in \>100 studies. This observational instrument covers 5 items and is typically administered at 4 perioperative time points. Minimum value is 23.33 and maximum value is 100. Scores below 30 are considered low anxiety. Score of 30 or more is considered high anxiety.

Preoperative Preparation Program (Child Life Specialist) : This group will receive the standard preoperative visit to the hospital with Child Life intervention
Pre-medication
Midazolam : 0.5 mg/kg oral midazolam
Parental Presence During Induction of Anesthesia
Parental Presence during Induction of Anesthesia : One parent will be present during induction of anesthesia of the child. The parent will be accompanied out of the OR by a nurse once the induction is completed. These parents will have completed a parent preparation program.

PRIMARY outcome

Timeframe: Induction, up to 10 minutes

Population: The discrepancy noted in the analysis population is due to missing data.

A total score is the number of categories checked (1-10). A perfect induction is when a patient does not exhibit negative behaviors, fear, or anxiety. A perfect score would be 0. icc 1 = Crying, tears in eyes icc 2 = Turns head away from mask icc 3 = Verbal refusal, says "no" icc 4 = Verbalization indicating fear or worry, "Where's mommy?" or "Will it hurt?" icc 5 = Pushes mask away with hands, pushes nurse/anesthesiologist with hands/feet icc 6 = Covers mouth/nose with hands/arms or buries face icc 7 = Hysterical crying, may scream icc8 = Kicks/flails legs/arms, arches back, and/or general struggling icc9 = Requires physical restraint icc10 = Complete passivity either rigid or limp icc 0 = Perfect induction

Population: The discrepancy noted in the analysis population is due to missing data

Parent-ranted child pain on the Visual Analogue Scale. The VAS for pain is a unidimensional measure of pain presented in a horizontal line from 0-100. A higher score indicates greater pain intensity. 0-4= no pain/anxiety, 5-44= mild pain/anxiety, 45-74 = moderate pain/anxiety, 75-100 = severe pain/anxiety.
