UASSIGNED:为了比较膈呼吸和容量激励肺活量测定(VIS)对血液动力学的影响,肺功能,全麻下开腹手术后患者的血气和血气。
UNASSIGNED:共有58名接受开腹手术的患者被随机分配到对照组(n=29)进行膈呼吸锻炼和VIS组(n=29)进行VIS锻炼。所有参与者在术前进行了六分钟步行测试(6MWT)以评估其功能能力。血流动力学指标,肺功能检查,术前和1日记录血气指标,3rd,术后第5天。
UNASSIGNED:术前两组患者的功能能力差异无统计学意义(P>0.05)。术后3天和5天,VIS组患者的SpO2明显高于对照组(P<0.05)。两组患者术后肺功能测试值均较术前降低,但术后3天和5天改善(P<0.05)。值得注意的是,峰值呼气流量(PEF)水平显着升高,第一秒用力呼气量(FEV1),强迫肺活量(FVC),1日观察到FEV1/FVC比值,3rd,术后第5天VIS组与对照组比较差异有统计学意义(P<0.05)。此外,低音过量(BE),术后第1天VIS组pH值明显高于对照组(P<0.05)。
UnASSIGNED:膈肌呼吸和VIS可以改善术后肺功能,但是VIS运动可能是改善血液动力学的更好选择,肺功能,开腹手术后患者的血气,从而降低术后肺部并发症的发生率。
UNASSIGNED: To compare the effect of diaphragmatic breathing and volume incentive spirometry (VIS) on hemodynamics, pulmonary function, and blood gas in patients following open abdominal surgery under general anesthesia.
UNASSIGNED: A total of 58 patients who received open abdominal surgery were randomly assigned to the control group (n=29) undergoing diaphragmatic breathing exercises and the VIS group (n=29) undergoing VIS exercises. All the participants performed the six-minute walk test (6MWT) preoperatively to evaluate their functional capacity. Hemodynamic indexes, pulmonary function tests, and blood gas indexes were recorded before surgery and on the 1st, 3rd, and 5th postoperative day.
UNASSIGNED: The functional capacity was not significantly different between the two groups during the preoperative period (P >0.05). At 3 days and 5 days postoperatively, patients in the VIS group had a significantly higher SpO2 than that in the control group (P <0.05). Pulmonary function test values were reduced in both two groups postoperatively when compared to the preoperative values but improved for three and five days afterward (P <0.05). Of note, the significantly elevated levels of peak expiratory flow (PEF), forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio were observed on the 1st, 3rd, and 5th postoperative days in the VIS group compared with those in the control group (P <0.05). Besides, bass excess (BE), and pH values were significantly higher in the VIS group on the 1st postoperative day than those in the control group (P <0.05).
UNASSIGNED: Diaphragmatic breathing and VIS could improve postoperative pulmonary function, but VIS exercise might be a better option for improving hemodynamics, pulmonary function, and blood gas for patients after open abdominal surgery, hence lowering the incidence of postoperative pulmonary complications.
