【摘要】目的 探讨主动脉内球囊反搏(IABP)辅助治疗二尖瓣手术后严重急性左心功能不全的临床效果。方法 选取2015年1月至2017年6月首都医科大学附属北京安贞医院收治的因二尖瓣手术后严重急性左心功能不全应用IABP辅助治疗的患者9例。观察应用IABP前以及应用IABP后24、72 h的心率、平均动脉压(MAP)、血浆脑钠肽、正性肌力药物评分(IS)、左心室射血分数(LVEF)、血乳酸水平等临床指标的变化。结果 本组患者全部脱离IABP并痊愈出院,IABP辅助时间65~92 h,平均(73±8)h。应用IABP辅助治疗24 h后患者的心率、MAP、脑钠肽、IS、LVEF、血乳酸水平均较应用IABP前明显好转[(108±6)次/min比(127±9)次/min、(64±5)mmHg(1 mmHg=0.133 kPa)比(55±7)mmHg、(806±137)ng/L比(1 961±321)ng/L、(18.9±2.7)μg/(kg·min)比(28.2±1.9)μg/(kg·min)、(38±3)%比(27±4)%、(3.61±0.83)mmol/L比(13.86±2.74)mmol/L],72 h后各项指标持续改善[心率(99±5)次/min、MAP(74±5)mmHg、脑钠肽(211±68)ng/L、IS(9.2±1.6)μg/(kg·min)、LVEF(49±3)%、血乳酸(1.71±0.36)mmol/L],差异均有统计学意义(均P<0.01)。治疗过程中1例女性患者出现放置IABP侧下肢皮温较对侧低,对症处理后随灌注压提高后改善,其他患者均未出现不良事件。结论 IABP对于二尖瓣手术后严重急性左心功能不全有良好的辅助治疗作用,应及时放置,并注意避免并发症。
【Abstract】Objective To explore the therapeutic effect of intra-aortic balloon pump(IABP) on severe acute left cardiac insufficiency after mitral valve surgery. Methods Nine patients with severe acute left cardiac insufficiency after mitral valve surgery who were treated with IABP in Beijing Anzhen Hospital, Capital Medical University from January 2015 to June 2017 were enrolled. Heart rate(HR), mean arterial pressure(MAP), plasma brain natriuretic peptide(BNP), inotropic drug score(IS), left ventricular ejection fraction(LVEF) and blood lactic acid(Lac) were analyzed before and 24, 72 h after IABP. Results All patients were cured and discharged after IABP with average supporting time of (73±8)h(65-92 h). After 24 h of IABP supporting, HR, MAP, BNP, IS, LVEF and Lac were significantly improved compared to those before treatment[(108±6),(99±5)times/min vs (127±9)times/min; (64±5),(74±5)mmHg vs (55±7)mmHg; (806±137),(211±68)ng/L vs (1 961±321)ng/L; (18.9±2.7),(9.2±1.6)μg/(kg·min) vs (28.2±1.9)μg/(kg·min); (38±3)%,(49±3)% vs (27±4)%; (3.61±0.83),(1.71±0.36)mmol/L vs (13.86±2.74)mmol/L](P<0.01); HR, MAP, BNP, IS, LVEF and Lac were continuously improved after 72 h of IABP supporting[(99±5)times/min, (74±5)mmHg, (211±68)ng/L, (9.2±1.6)μg/(kg·min), (49±3)%, (1.71±0.36)mmol/L](P<0.05). A female patient had lower limb skin temperature decreasing at the IABP side, which was ameliorated after increasing perfusion pressure. No adverse reaction was observed in other patients. Conclusion IABP shows a good adjuvant therapeutic effect on severe acute left cardiac insufficiency after mitral valve surgery.
