目的

俯卧位通气(prone position ventilation, PPV)是重症监护病房(intensive care unit, ICU)呼吸衰竭患者重要的肺保护性治疗手段,临床采用普通辅助垫实施俯卧位通气治疗时,易出现胸腹部受压干扰循环状态、皮肤压力性损伤、管路移位滑脱、呕吐误吸等,同时传统人工叩背排痰排痰效率有限,影响俯卧位通气治疗安全性与临床疗效。探讨多角度PPV辅助装置联合振动排痰仪对ICU呼吸衰竭患者血流动力学、动脉血气和相关并发症的影响,为ICU呼吸衰竭患者俯卧位通气的规范化、安全化实施提供临床参考依据。

方法

选择2024年10月至2026年2月我院收治的呼吸衰竭患者51例,随机分为对照组26例和观察组25例;对照组采用辅助垫联合人工叩背排痰,观察组使用多角度PPV联合振动排痰仪进行体位引流管理;比较两组中心静脉压(central venous pressure, CVP)、心输出量(cardiac output, CO)、每搏变异量(stroke volume variation, SVV)和心脏指数(cardiac index, CI);动脉血氧饱和度(arterial oxygen saturation, SaO2)、动脉血氧分压(partial pressure of oxygen in arterial blood,PaO2)和氧合指数(PaO2/FiO2)、并发症发生率。

结果

俯卧位通气6 h观察组血流动力学指标CO[(4.11±0.62)L/min 比(3.42±0.95)L/min]、SVV[(9.55±2.25)% 比 (11.11±2.08)%]、CI[(3.47±0.27)L/(min·m2) 比 (3.03±0.26)L/(min·m2)]优于对照组(P<0.05);观察组第3天SaO2、PaO2和PaO2/FiO2与对照组差异无统计学意义(P>0.05),第7天观察组SaO2[(92.39±2.10)% 比 (90.93±1.93)%]、PaO2[(90.12±1.93)mmHg 比 (88.59±2.75)mmHg]、PaO2/FiO2[(364.07±21.02)比 (351.77±17.92)]高于对照组(P<0.05)。观察组发生皮肤压力性损伤(1例 比5例)、管道滑脱(0例比3例)、呕吐(1例 比4例)、误吸(0例比4例)低于对照组;观察组单次吸痰操作时间[(56.76±8.22)s 比 (86.16±7.65)s]低于对照组(P<0.05)。观察组存活18例(72.00%),死亡7例(28.00%);对照组存活18例(69.23%),死亡8例(30.77%)。

结论

多角度俯卧位辅助装置联合振动排痰仪可改善重症监护病房呼吸衰竭患者血流动力学指标、动脉血气指标,降低相关并发症发生率,缩短吸痰时间。

Objective

Prone position ventilation (PPV) is an important lungprotective therapeutic measure for patients with respiratory failure in the intensive care unit (ICU). When conventional auxiliary cushions are used for prone position ventilation in clinical practice, complications such as impaired circulatory status caused by compression of the chest and abdomen, pressure injuries to the skin, displacement or dislodgement of pipelines, vomiting and aspiration tend to occur. Meanwhile, traditional manual back percussion for sputum clearance has limited efficiency, which compromises the safety and clinical efficacy of prone position ventilation therapy. To investigate the effects of the multiangle PPV auxiliary device combined with a vibration sputum expectoration instrument on hemodynamics, arterial blood gas parameters and related complications in ICU patients with respiratory failure, so as to provide clinical reference for the standardized and safe implementation of prone position ventilation for such patients.

Methods

Fifty-one patients with respiratory failure admitted to our hospital from October 2024 to February 2026 were selected and randomly divided into a control group (26 cases) and an observation group (25 cases). The control group received an auxiliary cushion combined with manual back percussion for sputum expectoration, while the observation group received multi-angle PPV combined with a vibration sputum expectoration instrument for postural drainage management. Central venous pressure (CVP), cardiac output (CO), stroke volume variation (SVV), and cardiac index (CI); arterial oxygen saturation (SaO2), partial pressure of oxygen in arterial blood (PaO2), oxygenation index (PaO2/FiO2), and the incidence of complications were compared between the two groups.

Results

At 6 h of prone position ventilation, the hemodynamic parameters in the observation group, including CO[(4.11 ± 0.62) L/min vs. (3.42±0.95)L/min], SVV[(9.55±2.25)% vs. (11.11±2.08)%], and CI[(3.47±0.27)L/(min·m2) vs. (3.03±0.26)L/(min·m2)], were superior to those in the control group (P<0.05). On day 3, there were no statistically significant differences in SaO2, PaO2, or PaO2/FiO2 between the observation group and the control group (P>0.05). On day 7, SaO2[(92.39±2.10)% vs. (90.93±1.93)%], PaO2[(90.12±1.93) mmHg vs. (88.59±2.75)mmHg], and PaO2/FiO2[(364.07±21.02) vs. (351.77±17.92)] in the observation group were higher than those in the control group (P<0.05). The observation group had lower incidences of pressure skin injury (1 case vs. 5 cases), tube dislodgement (0 cases vs. 3 cases), vomiting (1 case vs. 4 cases), and aspiration (0 cases vs. 4 cases) than the control group. The single sputum suctioning operation time in the observation group [(56.76±8.22)s vs. (86.16±7.65)s] was shorter than that in the control group (P<0.05). In the observation group, 18 patients survived (72.00%) and 7 died (28.00%); in the control group, 18 patients survived (69.23%) and 8 died (30.77%).

Conclusion

The multi-angle prone position assistive device combined with a vibration sputum expectoration instrument can improve hemodynamic and arterial blood gas parameters, the incidence of related complications, shorten sputum suctioning time of ICU patients with respiratory failure.
