摘  要:目的探讨同步悬空俯卧位对稳定期慢性阻塞性肺疾病(COPD)患者肺通气功能情况的影响。方法2009年6月至10月本院门诊就诊的12例稳定期COPD患者,在人工呼吸床上随机采用仰卧位、悬空俯卧位、托平俯卧位、同步悬空俯卧位4种不同体位,每个体位观察10min,通过NICO无创心肺功能监测系统连续测定患者在不同体位时的心率、动脉血氧饱和度、呼气末二氧化碳分压等一般生命体征和呼吸频率、潮气量、肺泡潮气量、生理无效腔(Vd/Vt)、吸气峰流速(PIF)、呼气峰流速(PEF)等呼吸动力学指标。根据患者的肺功能按美国胸科协会(ATS)和欧洲呼吸学会(ERS)制定的肺功能共同指南标准划分不同阻塞程度,并分析存在通气功能障碍患者的潮气量和呼吸频率等肺功能变化情况。结果4种体位对心率、动脉血氧饱和度、呼气末二氧化碳分压无明显的影响。呼吸频率在4种体位中由慢至快呈现同步悬空俯卧位〈仰卧位〈托平俯卧位〈悬空俯卧位的趋势[(14.8±3.2)次/min〈(17.6±4.5)次/min〈(18.4±3.4)次/min〈(19.5±3.4)次/min,均P〈0.05],潮气量和肺泡潮气量由高至低呈现同步悬空俯卧位〉仰卧位〉托平俯卧位〉悬空俯卧位的趋势。生理无效腔、PIF、PEF各组差异无统计学意义。3例重度和5例极重度阻塞通气功能障碍的患者潮气量在各体位间差异均无统计学意义,呼吸频率则在同步悬空俯卧位时最低,分别为(15.3±1.8)次/min、(16.6±1.8)次/min,且与悬空俯卧位时的呼吸频率差异有统计学意义[(19.4±3.4)次/min、(21.4±3.6)次/min,均P〈0.05]。结论同步悬空俯卧位与其他两种俯卧呼吸体位一样,经短时间观察是安全稳定的,同步悬空俯卧位显著降低患者的呼吸频率、增加潮气量。在阻塞性通气功能障碍的情况�Objective To investigate the impact of pulmonary ventilatory function of patients with stable chronic obstructive pulmonary disease (COPD) on simultaneous suspended prone position. Methods Twelve patients with stable COPD, who visited our clinic between June and October of 2009, were recruited in a series of assessments on a ventilation table using the supine position, suspended prone position, flat prone position and simultaneous suspended prone position in a randomized order, each position lasting 10 minutes. Non-invasive NICO cardiopulmonary monitoring system was used for continuous recording of vital signs (heart rate, arterial oxygen saturation, endtidal pressure of CO2) and respiratory mechanical parameters [respiratory rate, tidal volume, tidal volume of alveolus, physiological dead space(Vd/Vt), peak inspiratory flow (PIF) and peak expiratory flow (PEF) ] with each position. The patients were stratified by severity of airway obstruction based on ATS-ERS pulmonary function standards guidelines. Moreover, the changes in pulmonary function (such as tidal volume and respiratory rate) in patients with ventilatory dysfunction were analyzed. Results The four types of patient positioning did not obviously affect heart rate, arterial oxygen saturation and end-tidal pressure of COz. Respiratory rate in the 4 positions varied following the sequence of simultaneous suspended prone position 〈 supine position 〈 fiat prone position 〈 suspended prone position [ ( 14.8 ±3.2)/min 〈 ( 17.6±4.5 )/min 〈 ( 18.4±3.4)/min 〈 ( 19.5±3.4)/min; all P〈0.05 ]. Tidal volume and that of alveolus varied following the sequence of simultaneous suspended prone position 〉 supine position 〉 fiat prone position 〉 suspended prone position. There were no statistical differences in physiological dead space, PIF and PEF among groups. In 3 severe and 5 extremely severe cases with obstructive ventilatory dysfunction, the tidal volume did not vary significantly among these 4 positions, w
