【摘要】 目的观察单肺机械通气患者体位变更时氧疗的效果,并探讨其治疗机理及护理。方法将32例单肺机械通气患者随机分成实验组和对照组,实验组(18例)患者行体位变更机械通气,每1 h按仰卧位、健侧卧位、俯卧位、仰卧位顺序变换;对照组(14例)患者行常规持续仰卧位通气,两组均在通气后0.5 h、1.5 h、2.5 h、3.5 h做血气分析,比较两组患者相同时间段的氧合状态。结果实验组PaO2和PaO2/FiO2高于对照组,两组的PaCO2和血流动力学指标对比差异无意义。结论序贯性体位变更组与单一仰卧位机械通气比较,氧疗效果更好,成功脱离呼吸机时间缩短,临床护理易实施。更多还原

【Abstract】 Objective To observe the effect of oxygen therapy by single side lung ventilation and sequence change of body position,and to study treatment mechanism and nursing. Method 32 patients with single side lung ventilation were divided into experimental and control group.18 cases in experimental group were given mechanical ventilation by Sequence changing of body position,supine position,the normal side position,prone position,supine position changing of body position per hour.14 cases in control group has continuous routine ventilation by lying position,blood gas analysis were conducted 0.5 h,1.5 h,2.3 h,3.5 h after ventilation for comparing the saturation oxygen between the two groups.Result The PaO₂ and PaO₂/FiO₂ in experimental group were higher than that of control group.There were no difference in PaCO₂ and hemodynamics indicator between the two groups.Conclusion Compared with single supine position mechanical ventilation,the mechanical ventilation by Sequence changing of body position has better effect of oxygen therapy,shorter time of ventilation and easier for nursing.更多还原
