Abstract:
Objective To explore the therapeutic effect influencing factors of intra-aortic balloon pump(IABP) support during cardiac surgery perioperative period and countermeasures.Methods Clinical data of 42 patients using IABP in the cardiac surgery was analyzed retrospectively.The patients were classified into 2 groups:living group (32 patients) and died group (10 patients).The time of IABP implantation,preoperative cardiac function,the duration of cardiopulmonary bypass(CPB) and aorta block,mean arterial pressure (MAP) and inotropic score (IS) before using IABP and postoperative complications were recorded and compared.Results In died group,2 patients were used IABP preoperatively,1 patient was used intraoperatively,7 patients were used postoperatively,8 patients were in NYHA cardiac function class Ⅲ or Ⅳ preoperative,the duration of CPB and aorta block were (144.43 ± 49.03),(97.29 ± 39.99)min respectively,MAP and IS before using IABP were (57.34 ±7.25) mm Hg (1 mm Hg =0.133 kPa) and (28.22 ±17.72) scores,IABP time was (86.00 ±52.31) min.Compared with living group,all above comparisons showed significant difference [(100.43 ± 35.03) min,(60.45 ± 20.55) min,(69.34 ± 8.05)mm Hg,(10.82 ± 15.75) scores,(49.00 ± 25.23) min] (P ＜ 0.05).Postoperative complications in died group included 7 patients of ventilator dependency,6 patients of acute renal failure,5 patients of refractory metabolic acidosis,2 patients of malignant arrhythmia,1 patient of acute myocardial infarction,significantly higher than those in living group (0,4,2,0,0) (P ＜ 0.05).Conclusions Erroneously choose the timing of using IABP,poor preoperative cardiac function,prolonging CPB and aorta block time,MAP less than 60 mm Hg and high dose positive inotropic agent before using IABP,and postoperative complications are main influencing factors for clinical outcomes of IABP in cardiac surgery.Reasonably choosing adaptive indication and timing of IABP,preventing and treating postoperative complications effectively can improve effects of IABP in cardiac surgery.
