Clinical effect of right subaxillary small incision approach on children with congenital heart disease / 中华实用儿科临床杂志

ABSTRACT

Objective@#To analyze the clinical effect of right subaxillary small incision approach on children with congenital heart disease (CHD).@*Methods@#Eighty-six patients with CHD admitted to Henan Children′s Hospital from January 2015 to September 2017 were enrolled in this study.The patients were randomly divided into the control group and the observation group with 43 cases each group.The control group underwent sternal median incision, and the observation group underwent right subaxillary small incision.The total effective rate, incision satisfaction, general conditions of surgery (cardiopulmonary bypass time, operation time, aortic occlusion time, intraoperative blood loss), postoperative related conditions (thoracic drainage volume, postoperative monitoring time, postoperative assisted ventilation time, hospitalization time, hospitalization expenses), Wong-Baker facial expression scale (FPS-R) score, as well as the respiratory function index including the levels of peak inspiratory pressure (PIP) and alveolar-arterial oxygen pressure difference [p(A-a) (O2)]after anesthesia (T1), after operation (T2), at admission to intensive care unit (T3) and before extubation (T4) and complication rate between 2 groups were compared.@*Results@#(1)The incision satisfaction in the observation group [90.70% (39/43 cases)] was higher than that in the control group [62.79% (27/43 cases)], and the difference was statistically significant (χ2=9.382, P=0.002). (2)There was no significant difference in the the extracorporeal circulation time, operation time and aortic block time between the two groups [observation group (68.94±8.26) min, (2.33±0.21) h, (28.79±7.32) min; control group (67.11±9.11) min, (2.25±0.31) h, (30.02±6.88) min] (P>0.05). (3)The intraoperative blood loss [(89.87±11.25) mL] in the observation group was less than that in the control group [(105.91±31.01) mL], which difference was statistically significant (t=3.189, P=0.002). (4)Also there was significant difference in postoperative monitoring time, postoperative assisted ventilation time, hospitalization time, thoracic drainage volume and hospitalization expenses between the two groups (the observation group postoperative monitoring time (30.55±10.39) h, postoperative assisted ventilation time [(9.68±2.19) h, hospitalization time (9.61±2.17) d, thoracic drainage volume (90.36±26.14) mL, hospitalization expenses (36 956.15±1 097.84) yuan; the control group (41.39±9.93) h, (12.72±3.81) h, (12.33±3.15) d, (163.24±29.36) mL and (45 271.97±1 134.55) yuan] (t=4.946, 4.536, 4.663, 12.157, 34.540, all P<0.01). (5)FPS-R scores at 1, 2, 3, 4 d postoperatively in the observation group were (4.02±0.41), (3.41±0.15), (2.55 ±0.20) and (1.16±0.27) points, while those in the control group were respectively (5.21±0.89), (5.02±0.63), (4.12±0.67) and (3.05±0.39) points, which differences were statistically significant (t=7.963, 16.302, 14.724, 26.128, all P<0.01). (6)There was no significant difference in p(A-a) (O2) and PIP between the two groups at T1, T2, T3 and T4 (all P>0.05). There was no significant difference in the complication rate between the observation group [6.98% (3/43 cases)] and the control group [4.65% (2/43 cases)] (χ2=0.000, P>0.05).@*Conclusions@#Right subaxillary small incision approach does not affect the respiratory function of children with CHD, which can improve the satisfaction of incision, reduce the amount of blood loss, accelerate postoperative recovery of children, relieve postoperative pain, and reduce the financial burden of parents.Besides, intra-operative proficient and accurate operations can reduce or avoid the occurrence of related complications and ensure the safety of surgery.
