Brief summary

The aim of this study is to investigate the effect of addition of intranasal ketamine to midazolam compared to midazolam alone as a premedication on the occurrence of PRAEs

Detailed description

Perioperative respiratory adverse events (PRAEs) are the most common complication during pediatric anesthesia furthermore, most children presenting for AT have sleep-disordered breathing and obstructive sleep apnea syndrome (OSAS) caused by tonsillar hypertrophy which could aggravate the PRAEs specially with the use of the conventional sedatives as a premedication. A recent randomized controlled trial has shown that more than 50% of children premedicated with midazolam had experienced PRAEs . Midazolam and ketamine are commonly used as preoperative sedative drugs for pediatric populations. Ketamine is a safe and widely used sedative and analgesic in the pediatric emergency department (ED) with less profound effects on the upper airway and respiratory muscles. Intranasal ketamine administration is well tolerated and without serious adverse effects. The addition of ketamine to midazolam as a preoperative sedation to reduce the occurrence of PRAEs was not investigated before in children undergoing AT. The authors hypothesize that combination of ketamine to midazolam could offer optimum sedation condition while reducing the occurrence of PRAEs in children undergoing AT.

Interventions

DRUGThe midazolam group

The midazolam group will receive intranasal midazolam (0.1 mg/kg)

DRUGThe midazolam ketamine group

the midazolam ketamine group will receive intranasal midazolam (0.1mg/kg) and ketamine (3mg/kg)

QUADRUPLE (Subject, Caregiver, Investigator, Outcomes Assessor)

Masking description

The drug will be prepared by an anesthesia nurse who will not be involved in the study. The active drug will be administered by a fully trained anesthesiologist and Clear definitions of the respiratory adverse events will be provided to the involved anesthetist. All researchers directly involved in the study will be blinded to the drug which will be administered

Intervention model description

Children will be randomly assigned to 2 groups: the midazolam group will receive intranasal midazolam (0.1 mg/kg), and the midazolam ketamine group will receive intranasal midazolam (0.1mg/kg) and ketamine (3mg/kg) for premedication

Design outcomes

Primary

MeasureTime frameDescription
The incidence of any perioperative respiratory adverse events (PRAEs)8 hoursthe incidence of any PRAEs (Perioperative respiratory adverse events (PRAEs) which are manifested as minor (oxygen desaturation (SaO2 less than 95% for 10 seconds) or coughing) and major as (bronchospasm, laryngospasm, airway obstruction, stridor or hypoxia (oxygen desaturation less than 90%)) among midazolam versus midazolam ketamine groups.

Secondary

MeasureTime frameDescription
Postoperative pain score8 hours• Postoperative pain score using (Wong-Baker Pain Scale)
Sedation success rate8 hours• Sedation success rate (score of 3 or 4 is considered successful sedation) using Funk score
Postoperative emergence delirium8 hours• Postoperative emergence delirium, a total Postoperative emergence delirium PAED score≥ 10 will be considered indicative of the presence of ED using (PAED scale
