Study on the application effect of bed pedaling and chest enlargement exercise in weaning of ventilator-dependent patient and its effect on the success rate of weaning

目的探讨床上蹬车及扩胸锻炼在呼吸机依赖患者撤机中的应用效果及对撤机成功率的影响。方法 62例呼吸机依赖患者,随机分为研究组和对照组,各31例。对照组应用常规撤机方法 ,研究组应用床上蹬车及扩胸锻炼方法撤机。比较两组患者撤机情况、住院时间、呼吸机使用时间、住院费用、血压、心率。结果研究组撤机成功率为96.8%,明显高于对照组的77.4%,差异具有统计学意义(P<0.05)。研究组住院时间、呼吸机使用时间分别为(11.50±3.30)、(6.26±1.86)d,均短于对照组的(19.90±4.10)、(8.00±2.60)d,住院费用为(36112±4989)元少于对照组的(67221±11933)元,差异具有统计学意义(P<0.05)。研究组心率、舒张压、收缩压分别为(88.3±11.5)次/min、(68.3±6.8)mm Hg(1 mm Hg=0.133 kPa)、(118.3±8.9)mm Hg,均低于对照组的(100.4±12.3)次/min、(80.5±10.4)mm Hg、(133.7±11.3)mm Hg,差异具有统计学意义(P<0.05)。结论在呼吸机依赖患者撤机的过程中,床上蹬车及扩胸锻炼的应用效果较好,有效的提高了撤机的成功率,降低了患者的治疗费用。

Objective To discuss the effect of bed pedaling and chest enlargement exercise in weaning of ventilator-dependent patient and its effect on the success rate of weaning. Methods A total of 62 ventilator-dependent patients were randomly divided into research group and control group, with 31 cases in each group. The control group received conventional weaning method, and the research group received bed pedaling and chest enlargement exercise. Comparison were made on weaning condition, hospitalization time, ventilator use time, hospitalization cost, blood pressure and heart rate between the two groups. Results The research group had obviously higher success rate of weaning as 96.8% than 77.4% in the control group, and the difference was statistically significant(P<0.05). The research group had hospitalization time, ventilator use time respectively as(11.50±3.30) and(6.26±1.86) d than(19.90±4.10) and(8.00±2.60) d in the control group, and less hospitalization cost as(36112±4989) yuan than(67221±11933) yuan in the control group. Their difference was statistically significant(P<0.05). The research group had lower heart rate, diastolic blood pressure and systolic blood pressure respectively as(88.3±11.5) times/min,(68.3±6.8) mm Hg(1 mm Hg=0.133 kPa) and(118.3± 8.9) mm Hg than(100.4±12.3) times/min,(80.5±10.4)mm Hg and(133.7±11.3) mm Hg in the control group. Their difference was statistically significant(P<0.05). Conclusion Bed pedaling and chest enlargement exercise shows good effect in weaning of ventilator-dependent patient. It can effectively improve the success rate of weaning and lower the treatment costs of patients.
