Tympanostomy tube insertion is the most common pediatric surgery, but it typically requires general anesthesia. To facilitate in-office tube placement without general anesthesia, two complementary technologies have recently been developed comprising an iontophoresis system for delivering local anesthesia and an integrated tube delivery system. The purpose of this study was to evaluate behavioral support techniques used during a clinical study of the new technology for pediatric in-office tube placement without general anesthesia or physical restraints.
As part of an IRB-approved, prospective, nine-center clinical study, pediatric patients requiring tube insertion underwent in-office treatment using the new procedure. The behavior management techniques included preparation, distraction, coaching, and reinforcement for cooperation. The entire procedure was videotaped and two independent coders used the validated FLACC (Face, Legs, Activity, Cry, Consolability) scale to code behavioral distress across five procedural phases.
Seventy pediatric patients aged 8 months to 17 years (M=7.0 years; 51% female) were enrolled in the study and 68 had video recordings available for analysis. Of the 68 recordings analyzed, 63 patients completed the procedure and had tubes placed without sedation. Mean FLACC scores ranged from 0.05 to 2.38 (M=1.25, SD=0.82) and median FLACC scores ranged from 0 to 1 (Mdn=0, IQR=0.05), which indicate "mild" distress. During iontophoresis, eardrum tap (anesthesia assessment), and tube delivery, older children displayed lower distress and girls had higher FLACC scores during the eardrum tap procedural phase.
When combined with the evidence-based behavioral techniques, office-based local anesthesia and tube delivery resulted in minimal distress, suggesting that the new procedure may be a viable method of conducting tympanostomy tube placement in children without having to use general anesthesia.

鼓膜置管术是最常见的小儿外科手术,但通常需要全身麻醉。为便于在门诊无需全身麻醉进行置管,最近开发了两种互补技术,包括用于输送局部麻醉剂的离子导入系统和集成式导管输送系统。本研究的目的是评估在一项关于小儿门诊无需全身麻醉或身体约束的新技术临床研究中所使用的行为支持技术。
作为一项经机构审查委员会批准的前瞻性九中心临床研究的一部分,需要置管的儿科患者采用新方法在门诊接受治疗。行为管理技术包括准备、分散注意力、指导和对合作的强化。整个过程进行了录像,两名独立的编码员使用经过验证的FLACC(面部、腿部、活动、哭泣、安慰性)量表对五个操作阶段的行为痛苦程度进行编码。
70名年龄在8个月至17岁(平均年龄7.0岁;51%为女性)的儿科患者纳入研究,68名有可供分析的录像。在分析的68份录像中,63名患者完成了手术且在未使用镇静剂的情况下置入了导管。平均FLACC评分在0.05至2.38之间(平均=1.25,标准差=0.82),中位数FLACC评分在0至1之间(中位数=0,四分位距=0.05),表明为“轻度”痛苦。在离子导入、鼓膜轻拍(麻醉评估)和导管输送过程中,年龄较大的儿童表现出较低的痛苦程度,而女孩在鼓膜轻拍操作阶段的FLACC评分较高。
当与循证行为技术相结合时,门诊局部麻醉和导管输送导致的痛苦最小,这表明新方法可能是一种在儿童中进行鼓膜置管术而无需使用全身麻醉的可行方法。Clinicaltrials.gov标识符:NCT01496287。
