Laryngotracheal reconstruction (LTR) involves surgical correction of a stenotic airway with cartilage interpositional grafting, followed by either placement of a tracheostomy and an intraluminal stent (two-stage LTR) or placement of an endotracheal tube with postoperative sedation and mechanical ventilation for an extended period of time (singlestage LTR). With single-stage repair, there may be several perioperative challenges including the provision of adequate sedation, avoidance of the development of tolerance to sedative and analgesia agents, the need to use neuromuscular blocking agents, the maintenance of adequate pulmonary toilet to avoid perioperative nosocomial infections, and optimization of postoperative respiratory function to facilitate successful tracheal extubation. We review the perioperative management of these patients, discuss the challenges during the postoperative period, and propose recommendations for the prevention of reversible causes of extubation failure in this article. Optimization to ensure a timely tracheal extubation and successful weaning of mechanical ventilator, remains the primary key to success in these surgeries as extubation failure or the need for prolonged postoperative mechanical ventilation can lead to failure of the graft site, the need for prolonged Pediatric Intensive Care Unit care, and in some cases, the need for a tracheostomy to maintain an adequate airway.
喉气管重建术(LTR)包括通过软骨植入移植对狭窄气道进行手术矫正,随后要么放置气管造口术和腔内支架(两阶段LTR),要么放置气管内导管并在术后长时间进行镇静和机械通气(单阶段LTR)。对于单阶段修复,可能存在几个围手术期挑战,包括提供充分的镇静、避免对镇静和镇痛药物产生耐受性、使用神经肌肉阻滞剂的必要性、保持充分的肺部清洁以避免围手术期医院感染,以及优化术后呼吸功能以促进成功的气管拔管。我们在本文中回顾了这些患者的围手术期管理,讨论了术后期间的挑战,并提出了预防该类拔管失败可逆原因的建议。优化以确保及时气管拔管和成功撤机机械通气,仍然是这些手术成功的首要关键,因为拔管失败或术后需要长时间机械通气可导致移植部位失败、需要在儿科重症监护病房进行长时间护理,在某些情况下,还需要气管造口术以维持足够的气道。
