在腹部手术后的正气压治疗暂时增加氧和,但导致低通风和脱等不良影响. 这种疗法对假冒干预没有显著的益处.
科学领域:
- 呼吸系统生理学 呼吸系统生理学
- 术后护理 术后护理
- 临床试验 临床试验
背景情况:
- 阳性呼气压 (PEP) 疗法通常用于治疗术后缺氧.
- 证据支持PEP治疗对这种适应症的疗效是有限的.
- 这项研究调查了PEP治疗对术后患者的直接影响.
研究的目的:
- 评估正气压 (PEP) 治疗对腹部手术后患者氧和和通风的直接影响.
- 为了比较PEP疗法的效果与假冒干预和深呼吸机动.
主要方法:
- 在腹部手术后1-2天,对成年人进行了一项随机化,模拟控制的交叉试验.
- 干预涉及PEP治疗10-15厘米H2O,用假装设备作为对照.
- 测量结果包括周边氧和和皮肤间二氧化碳部分压力 (PtcCO2) 的变化.
主要成果:
- 在PEP呼吸过程中,氧和增加了 (92%至95%),PtcCO2降低了 (36至33mm Hg).
- 其次是呼吸暂停,氧气不和 (89%),并增加了PtcCO2.
- 观察到的氧和和PtcCO2的变化与假呼吸或深呼吸机动没有显著差异.
结论:
- 由于高通风,PEP治疗暂时改善腹部手术后的氧气和,但随后会出现低通风和脱等不良影响.
- 培普治疗的效果并不优于假装设备或高通风.
- 这些发现表明,由于缺乏已证明的益处和报告的不良反应,应重新考虑对腹部手术后患者的PEP治疗.
