Effect of Hypercapnia Treatment on Respiratory Recovery after Spinal Cord Injury

项目摘要 标题：高碳酸血症治疗对脊髓损伤后呼吸恢复的影响 损伤 呼吸系统和心血管并发症是最常见的死亡原因， 受伤后的第一年。近80%的SCI患者，包括退伍军人， 在受伤六个月后出现呼吸和睡眠障碍。然而，大多数患者 SCI不能耐受标准的机械治疗，导致缺乏依从性。 因此，确定其他治疗方法对于这种常见疾病很重要， 一般人群中的不良结局（心脏病、中风、高血压和 认知）。据报道，在SCI患者中， 急性间歇性低氧技术可改善呼吸和运动恢复。的 间歇性缺氧的效果取决于肺泡二氧化碳（CO2）的水平 并且可能造成不希望的心血管效应。然而，高碳酸血症的影响 在SCI患者清醒和睡眠期间单独使用对呼吸恢复的影响 未知 本申请的目的是确定呼吸系统疾病的新治疗干预措施。 和睡眠障碍。本申请建议进行一项试点研究， 招募30名SCI退伍军人，每天接受两周急性间歇性高碳酸血症治疗 （dAIHc）治疗。将有三个具体目标来解决以下假设： 具体目标（1）：衡量试点干预措施的招募率和可行性 在SCI患者中使用dAIHc。 具体目的（2）：检验dAIHc将增加每分钟通气量的假设， SCI患者的呼吸肌力量。 具体目标（3）：检验dAIHc将改善睡眠参数的假设， SCI患者。

Project Summary Abstract Title: Effect of Hypercapnia Treatment on Respiratory Recovery after Spinal Cord Injury. Respiratory and cardiovascular complications are the most common causes of death in the first year post-injury. Nearly 80% of patients with SCI, including Veterans, suffer from breathing and sleep disorders after six months of injury. However, most patients with SCI do not tolerate standard mechanical treatment leading to a lack of adherence. Therefore, identifying other therapies is important for this common condition linked to poor outcomes in the general population (heart disease, stroke, hypertension, and poor cognition). In individuals with SCI, it has been reported that chemical stimulation using acute intermittent hypoxia techniques improves ventilatory and motor recovery. The effect of intermittent hypoxia is dependent on the level of alveolar Carbon Dioxide (CO2) and may pose undesirable cardiovascular effects. However, the effect of hypercapnia alone on respiratory recovery during wakefulness and sleep in patients with SCI is unknown. The purpose of this application is to identify new therapeutic interventions for respiratory and sleep disorders in Veterans with SCI. This application proposes a pilot study to enroll 30 Veterans with SCI to receive two weeks of daily acute intermittent hypercapnia (dAIHc) treatment. There will be three specific aims to address the following hypotheses: Specific Aim (1): Measure the recruitment rate and feasibility of a pilot intervention using dAIHc in individuals with SCI. Specific Aim (2): Test the hypothesis that dAIHc will increase minute ventilation and respiratory muscle forces in individuals with SCI. Specific Aim (3): Test the hypothesis that dAIHc will improve sleep parameters in individuals with SCI.
