Microsurgical free tissue transfer has been successfully implemented for various reconstructive applications in children. The goal of this study was to identify the best available evidence on perioperative management of pediatric patients undergoing free tissue transfer and to use it to develop evidence-based care guidelines.
A systematic review was conducted in the PubMed, Embase, Scopus, and Cochrane Library databases. Because a preliminary search of the pediatric microsurgical literature yielded scant data with a low level of evidence, pediatric anesthesia guidelines for healthy children undergoing major operations were also included. Exclusion criteria included vague descriptions of perioperative care, case reports, and studies of syndromic or chronically ill children.
Two hundred four articles were identified, and 53 met inclusion criteria. Management approaches specific to the pediatric population were used to formulate recommendations. High-quality data were found for anesthesia, analgesia, fluid administration/blood transfusion, and anticoagulation (Level I Evidence). Lower quality evidence was identified for patient temperature (Level III Evidence) and vasodilator use (Level IV Evidence). Key recommendations include administering sevoflurane for general anesthesia, implementing a multimodal analgesia strategy, limiting preoperative fasting, restricting blood transfusions until hemoglobin level is less than 7 g/dl unless the patient is symptomatic, and reserving chemical venous thromboembolism prophylaxis for high-risk patients.
Pediatric-specific guidelines are important, as they acknowledge physiologic differences in children, which may be overlooked when extrapolating from adult studies. These evidence-based recommendations are a key first step toward standardization of perioperative care of pediatric patients undergoing plastic surgical procedures, including free tissue transfer, to improve outcomes and minimize complications.
显微游离组织移植已成功应用于儿童的各种重建手术。本研究旨在确定关于接受游离组织移植的儿童患者围手术期管理的最佳现有证据,并利用这些证据制定循证护理指南。
在 PubMed、Embase、Scopus 和 Cochrane Library 数据库中进行了系统评价。由于初步搜索小儿显微外科文献得到的数据很少,且证据水平较低,因此也纳入了健康儿童接受大手术的小儿麻醉指南。排除标准包括围手术期护理描述含糊、病例报告和对综合征或慢性疾病儿童的研究。
共确定了 204 篇文章,其中 53 篇符合纳入标准。采用特定于儿科人群的管理方法制定了建议。麻醉、镇痛、液体管理/输血和抗凝(I 级证据)方面有高质量数据。患者体温(III 级证据)和血管扩张剂使用(IV 级证据)方面的证据质量较低。主要建议包括使用七氟醚进行全身麻醉、实施多模式镇痛策略、限制术前禁食、限制输血,除非患者出现症状,否则血红蛋白水平应低于 7g/dl,仅将化学性静脉血栓栓塞预防用于高危患者。
儿科特定指南很重要,因为它们承认儿童的生理差异,而从成人研究推断时可能会忽略这些差异。这些基于证据的建议是标准化接受整形手术(包括游离组织移植)的儿科患者围手术期护理的关键第一步,旨在改善结果并尽量减少并发症。
