摘    要:Objective To investigate the effect of the timing of intra?aortic balloon counterpulsation (IABP) treatment on the clinical efficacy of patients after severe cardiac surgery. Methods A prospective study was conducted on 64 patients with IABP after cardiac surgery in Gaozhou People′ s Hospital of Guangdong Province from March 2018 to March 2020. According to the time of IABP treatment,33 patients were divided into early treatment group ( severe cardiac surgery<6 h) and late 31 cases in treatment group (≥6 h after severe cardiac surgery):two groups of mean arterial pressure( MAP),left ventricular ejection fraction (LVEF),mechanical ventilation time,IABP indwelling time,ICU stay time,central venous oxygen saturation ( ScvO2 ), N terminal pro B type natriuretic peptide ( NT?proBNP ), lactate clearance rate, complications and follow?up. Results After 48 hours of IABP,MAP and LVEF in the early treatment group were (79. 47±7. 07) mmHg and (45. 20±3. 86)%,respectively,and those in the late treatment group were (71. 38±6. 26) mmHg and (41. 66±4. 49)%. There were significant differences between the two groups (t value was 34.604,29.375 respectively all P < 0. 01) . The mechanical ventilation time ( 71. 56 ± 5. 98) h, IABP indwelling time (68 31±10. 10) h,ICU stay time (5. 84±1. 04) d in the early treatment group,and those in the late treatment group ( 82. 79 ± 4. 96) h, ( 89. 49 ± 9. 97) h, ( 6. 82 ± 1. 07) d. There were significant differences between the two groups ( t value was 70. 093, 72. 855, 31. 859 respectively, all P <0. 01). The ScvO2 , NT?pro BNP and lactate clearance rate in the early treatment group were ( 71. 66 ±5. 45)%,(1 698. 36±1 032. 98) ng / L and ( 30. 12 ± 2. 29)%,respectively at 48 hours after IABP,and those in the late treatment group (66. 03± 4 61)%,( 2 898. 43 ± 1 383. 29) ng / L and ( 20. 47 ± 1. 92)% . There were significant differences between the two groups ( t value was 38.279,34.379 respectively,all P <0. 01). The incidence of complications were 18% ( 6 / 33) and 41. 94% ( 13 / 31) in the early treatment group and the late treatment group. There was significant difference between the two groups( P = 0. 038). Conclusion Early use of IABP treatment can improve the patients′ hemodynamic and serological indicators, reduce the patient′ s mechanical ventilation time, IABP time, ICU monitoring time and complications. © 2021, Chinese Medical Journals Publishing House Co.Ltd.
