简要总结
During induction of anesthesia in children, the investigators have observed significant variability in mask holding technique at our institution among different anesthesia practitioners. Some hold the face mask using one hand and others use two hands. The aim of our study is to comparatively evaluate the extent of airway obstruction in children whilst anesthetic mask is held with one hand with jaw thrust versus mask held using two hands with chin lift by anesthesia provider during induction of anesthesia in children.
详细描述
In a prospective, randomized and controlled study, 60 children with documented obstructive sleep apnea (from sleep study or history obtained from the parent of bothersome snoring, witnessed apnea which interrupts the snoring and/or gasping and choking sensations that arouse the patient from sleep) due to enlarged tonsils and adenoid scheduled for tonsillectomy and adenoidectomy surgery will be enrolled in the study. Children will be randomly divided in three groups of 20 each based on the induction technique used:
Group --1: Induction of anesthesia started as follows while children are breathing spontaneously: One handed mask airway + chin lift - 20 sec and then switch to two hands + jaw thrust - 20 sec
Group 2 - Induction of anesthesia started as follows while children are breathing spontaneously: Two handed mask airway + jaw thrust - 40 sec
Group 3 - Induction of anesthesia started as follows while children are breathing spontaneously: Two handed mask airway + jaw thrust - 20 sec and then switch to one hand + chin lift- 20 sec
Premedication with midazolam as per standard protocol, will be administered prior to taking the patients to the operating room. Prior to the induction of anesthesia, a shoulder role will be used to have the child's head in sniffing position for induction. Horizontal alignment of the external auditory meatus with the sternum, will be used as a marker for, proper positioning.
