Children with neuromuscular, chronic neurologic, and chest wall diseases are at increased risk of postoperative respiratory complications including atelectasis, pneumonia, and respiratory failure with the possible need for reintubation or even tracheostomy. These complications negatively impact patient outcomes, including increased healthcare resource utilization and increased surgical mortality. In these children, the existing respiratory reserve is often inadequate to withstand the stresses brought on during anesthesia and surgery. A thorough clinical assessment and objective evaluation of pulmonary function and gas exchange can help identify which children are at particular risk for poor postoperative outcomes and thus merit preoperative interventions. These may include initiation and optimization of non-invasive ventilation and mechanical insufflation-exsufflation. Furthermore, such an evaluation will help identify children who may require a postoperative extubation plan tailored to neuromuscular diseases. Such strategies may include avoidance of pre-extubation lung decruitment by precluding continuous positive airway pressure trials, aggressively weaning to room air and directly extubating to non-invasive ventilation with a high inspiratory to expiratory pressure differential of at least 10 cm H20. Children with cerebral palsy and other neurodegenerative or neurodevelopmental disorders are a more heterogeneous group of children who may share some operative risk factors with children with neuromuscular disease; they may also be at risk of sleep-disordered breathing, may also require non-invasive ventilation or mechanical insufflation-exsufflation, and may have associated chronic lung disease from aspirations that may require perioperative treatment.
患有神经肌肉疾病、慢性神经系统疾病和胸壁疾病的儿童术后发生呼吸并发症的风险增加,包括肺不张、肺炎和呼吸衰竭,可能需要再次插管甚至气管切开术。这些并发症会对患者的预后产生负面影响,包括增加医疗资源的使用和手术死亡率。在这些儿童中,现有的呼吸储备往往不足以承受麻醉和手术期间带来的压力。全面的临床评估以及对肺功能和气体交换的客观评估有助于确定哪些儿童术后预后不良的风险特别高,因此值得进行术前干预。这些干预措施可能包括启动和优化无创通气以及机械吸气-呼气。此外,这样的评估将有助于确定哪些儿童可能需要根据神经肌肉疾病制定术后拔管计划。此类策略可能包括通过避免持续气道正压试验来避免拔管前肺萎陷,积极撤机至室内空气,并直接拔管至无创通气,吸气与呼气压力差至少为10厘米水柱。患有脑瘫和其他神经退行性或神经发育障碍的儿童是一组更为异质的儿童,他们可能与患有神经肌肉疾病的儿童有一些共同的手术风险因素;他们也可能有睡眠呼吸障碍的风险,可能也需要无创通气或机械吸气-呼气,并且可能因误吸而患有相关的慢性肺病,这可能需要围手术期治疗。
