摘要:
目的:探讨右美托咪定结合经鼻高流量湿化氧疗(HFNC)对急性心力衰竭合并呼吸衰竭患者心率变异性、缺氧状态及趋化因子水平的影响。方法:选取收治的急性心力衰竭合并呼吸衰竭患者120例,采取随机数字表法分为两组,各60例,两组患者均采取常规扩血管、利尿等治疗,对照组给予经鼻高流量湿化氧疗治疗,观察组在其基础上增加右美托咪定治疗,比较两组患者临床疗效、呼吸及心功能指标[心率(HR)、呼吸频率(RR)、左室射血分数(LVEF)]、血气指标[血氧饱和度(SpO2)、动脉血氧分压(PaO2)、二氧化碳分压(PCO2)]、心率变异性(HRV)及趋化因子水平;比较两组患者HFNC 时间、气管插管和谵妄以及病死率。结果:观察组临床疗效要明显优于对照组,差异有统计学意义(P<0.05)。两组患者治疗后与治疗前比较HR、RR较低,LVEF较高,SpO2、PaO2较高,PCO2较低,HRV较高,趋化因子水平较低,观察组治疗后与对照组治疗后比较,HR、RR较低,LVEF较高,SpO2、PaO2较高,PCO2较低,HRV较高,趋化因子水平较低,差异有统计学意义(均P<0.05)。观察组与对照组比较HFNC时间较短,气管插管率较低、谵妄发生率较低,差异有统计学意义(均P<0.05)。两组患者病死率比较,差异无统计学意义(P>0.05)。结论:右美托咪定结合经鼻高流量湿化氧疗可显著改善急性心力衰竭合并呼吸衰竭患者的呼吸及心功能指标,改善血气指标,调节心率变异性及趋化因子水平,获得更好的预后。
Abstract:
Objective:To investigate the impact of dexmedetomidine combined with highflow nasal cannula (HFNC) therapy on heart rate variability (HRV),hypoxia status,and chemokine levels in patients with acute heart failure (AHF) and respiratory failure (RF).Methods:A total of 120 patients with AHF and RF,were randomly divided into two groups of 60 each.Both groups received standard treatments,including vasodilators and diuretics.The control group received HFNC therapy,while the observation group received HFNC therapy combined with dexmedetomidine.Clinical efficacy,respiratory and cardiac function indicators [heart rate (HR),respiratory rate (RR),left ventricular ejection fraction (LVEF)],blood gas indicators [oxygen saturation (SpO2),arterial oxygen partial pressure (PaO2),carbon dioxide partial pressure (PCO2)],HRV,and chemokine levels were compared between the two groups.AD-Ditionally,HFNC duration,intubation rate,delirium occurrence,and mortality rate were compared.Results:The observation group showed significantly better clinical efficacy than the control group (P<0.05).Posttreatment,both groups had significantly lower HR,lower RR,higher LVEF,higher SpO2,higher PaO2,lower PCO2,higher HRV,and lower chemokine levels compared to pretreatment (all P<0.05).Compared to the control group,the observation group had significantly lower HR,lower RR,higher LVEF,higher SpO2,higher PaO2,lower PCO2,higher HRV,and lower chemokine levels posttreatment (all P<0.05).The observation group also had shorter HFNC duration,lower intubation rate,and lower delirium occurrence compared to the control group (all P<0.05).There was no significant difference in mortality rates between the two groups (P>0.05).Conclusion:Dexmedetomidine combined with HFNC can significantly improve respiratory and cardiac function indicators,blood gas indicators,HRV,and chemokine levels in patients with AHF and RF,leading to better prognosis.
