전신 마취를 받는 소아에서 i-gelTM의 임상적 평가 = A clinical evaluation of i-gelTM during general anesthesia in children

다국어 초록 (Multilingual Abstract)

Background: The i-gelTM (i-gel) is a new single-use supraglotticairway device with a non-inflatable cuff. This study investigated thesafety and efficacy of the i-gel during general anesthesia in children.
Methods: Ninety-eight children at ASA physical status I-II whounderwent general anesthesia were included in this prospectiveobservatory study. The size of the i-gel was selected based onpatient’s body weight. We evaluated success rates, insertion time,airway leak pressure, fiberoptic examination, airway manipulation,airway quality, and postoperative complications.
Results: The first-attempt success rate was 96.9% with overallsuccess rate of 98.0%. The insertion time was 15.6 ± 4.7 seconds. The airway leak pressure was 28.2 ± 5.9 cmH2O. The maximal peakinspiratory pressure was 15.4 ± 3.0 cmH2O. On fiberoptic examination,vocal cords were visible in 86.5% of patients. During maintenanceof anesthesia, manipulations of i-gel were required for 32 (33.3%)children to maintain airway. Controlled ventilation was possible inall cases, although excess leak transiently occurred in threechildren. Postoperative complications including blood-staining ondevice, cough, and sore throat were infrequent.
Conclusions: The i-gel size at 1.5–2.5 provided a satisfactoryairway and ventilation during anesthesia in children. However, i-gelrequired a number of manipulations to maintain patency of airwayduring general anesthesia.
