Abstract:
Objective:To investigate the safety and effect of the operation of the upper sternum small incision assisted by normothermic cardiopulmonary bypass in the treatment of aortic valve disease.Methods:From March 2014 to June 2016, the clinical data of 25 patients who underwent single incision minimally invasive aortic valve replacement assisted by normothermic cardiopulmonary bypass in The Second Hospital of Hebei Medical University and 25 patients who underwent aortic valve replacement under hypothermia cardiopulmonary bypass were analyzed retrospectively.The former was used as minimally invasive surgery group, and the sternum was sawn in " J" shape through a small incision on the upper sternum.In the latter group, aortic valve replacement was performed under cardiopulmonary bypass.The operation effect and complications of the two groups were compared.Results:There was no death in the two groups.There was no significant difference in operation time between minimally invasive surgery group and routine operation group ( P>0.05). The time of aortic occlusion and cardiopulmonary bypass in minimally invasive surgery group ((50.0±6.8), (69.5±9.7) min) was longer than those in routine operation group ((45.8±7.2), (65.0±8.8) min), the difference was statistically significant ( t=2.120, 2.052, all P<0.05). In the minimally invasive operation group, red cell volume, plasma volume, intraoperative bleeding volume, incision length, postoperative 24-h drainage volume, postoperative 24-h leukocyte count, postoperative 24-h C-reactive protein concentration, postoperative 24-h total blood transfusion volume, ventilator-assisted time, ICU stay time and drainage tube retention time(85.1(42.3, 181.3) ml, 108.5(79.4, 173.8) ml, 186.4(132.6, 307.6) ml, (4.2±0.8) cm, 130.0(88.1, 224.3) ml, 14.2(9.8, 17.1)×10 9/L, 14.0(9.9, 23.2) mg/L, 186.6(135.3, 302.1) ml, 3.7(2.3, 6.8) h, 25.2(20.6, 35.6) h, 31.2(26.4, 41.9) h) were lower than those in the routine operation group (354.2(150.2, 507.2) ml, 211.9(119.2, 281.5) ml, 378.4(220.9, 496.5) ml, (13.8±6.5) cm, 365.8(171.8, 511.3) ml, 20.4(13.6, 24.7)×10 9/L, 28.6(14.4, 39.3) mg/L, 405.1(185.3, 570.1) ml, 7.7(4.2, 10.2) h, 52.8(30.8, 69.3) h, 57.2(37.6, 71.9) h), the difference between the two groups was statistically significant ((the statistical values were Z=3.393, 2.696, 2.781, t=7.329, Z=3.151, 2.638, 2.493, 2.597, 2.472, 3.254, 3.338, respectively; all P<0.05). There was no significant difference between the minimally invasive operation group and the routine operation group( P>0.05). The total incidence of postoperative complications in the minimally invasive operation group and the routine operation group was (12% (3/25) and 44% (11/25)), the difference was statistically significant ( P=0.025). Conclusion:CPB with normal temperature has the advantages of less trauma, fewer complications and faster recovery in the operation of single incision in the upper part of sternum.
