The size of the ProSeal laryngeal mask airway in children is determined by the patient's weight. However, in some instances, an alternative method may be required. This study aimed to compare sizing by the auricle with conventional ProSeal laryngeal mask airway sizing by weight in children.
After approval by the institutional ethics board and written informed consent from parents, 197 children with American Society of Anesthesiologists physical status I-II who were scheduled for a routine genitourinary operation were included in the study. The correct ProSeal laryngeal mask airway size was determined according to the size of the auricle in children. The results were compared with the standard weight-based method recommended by the manufacturer's guidelines. The patients were classified into different groups depending on the ProSeal laryngeal mask airway sizes as determined by both methods. Agreement between both techniques was evaluated with κ coefficient statistics.
Insertion and adequate ventilation were achieved in 185 patients at the first attempt, and 12 patients required a second attempt. Three patients had to be intubated. Agreement between the two methods of size selection of the ProSeal laryngeal mask airway was moderate using κ statistics.
Choosing the size of the ProSeal laryngeal mask airway in children according to the auricle of the child is valid and practical. In particular, this is an alternative method in situations where the patient's weight is unknown, such as in emergency situations.
儿童喉罩气道的尺寸由患者体重决定。然而，在某些情况下，可能需要一种替代方法。本研究旨在比较根据耳廓确定喉罩气道尺寸与传统的根据儿童体重确定喉罩气道尺寸的方法。
经机构伦理委员会批准并获得家长书面知情同意后，197例美国麻醉医师协会身体状况为I-II级、计划进行常规泌尿生殖系统手术的儿童纳入本研究。根据儿童耳廓大小确定合适的喉罩气道尺寸。将结果与制造商指南推荐的基于体重的标准方法进行比较。根据两种方法确定的喉罩气道尺寸将患者分为不同组。用κ系数统计评估两种技术之间的一致性。
185例患者首次尝试时成功插入并实现了充分通气，12例患者需要第二次尝试。3例患者必须进行气管插管。使用κ统计，两种选择喉罩气道尺寸的方法之间的一致性为中等。
根据儿童耳廓选择喉罩气道尺寸是有效且实用的。特别是，在患者体重未知的情况下，如紧急情况下，这是一种替代方法。
