Conditions parental/caregiver anxiety, child's anxiety
Treatments zolpidem, midazolam
Phase phase 3
Sponsor Loma Linda University
Start date July 2014
End date May 2016
Trial size 86 participants
Trial identifier NCT02096900, 5140032


The purpose of this investigator-initiated study is to compare the efficacy of oral midazolam and zolpidem for preoperative sedation, anxiety of patient, and caregiver anxiety at the time of separation, and ease of mask acceptance at induction in children. Subjects will be randomized to receive oral medication midazolam or zolpidem approximately 30 minutes prior to surgery. No placebo will be administered in this study. Subjects will be male and female children between 2 and 9 years of age. In total, subject participation will last approximately the duration of their preoperative, perioperative, and immediate postoperative period. A member of the research team will recruit subjects preoperatively in the operating room holding area prior to surgery. Consent will take place at the time of recruitment in the preoperative holding area following a detailed explanation of the study and medications involved in the study. Participants will be of ASA (American Society of Anesthesiologists) class I-II, undergoing surgical procedures of at least 2 hours duration, and expected to remain inpatient for at least 23 hours postoperatively.

Primary Outcomes

Patient anxiety at the time of separation
time frame: Study participation will be about 1 day including the preoperative, perioperative at the time of induction, and postoperative period

Secondary Outcomes

Other comparison measures will include preoperative parent/caregiver anxiety, anesthesia mask acceptance characteristics at the time of induction, and time to full recovery in the post operative period.
time frame: Secondary outcome measures will begin when the parent/caregiver completes the STAI questionnaire prior to the study medication being given to the subject.
