  • Risk factors for death after one-stage radical surgery in children with interruption of aortic arch and ventricular septal defect

    Objective To analyze the risk factors for death in children with interruption of aortic arch (IAA) and ventricular septal defect (VSD) after one-stage radical surgery. Methods A retrospective analysis was performed on patients with IAA and VSD who underwent one-stage radical treatment in the First Hospital of Hebei Medical University from January 2006 to January 2017. Cox proportional hazards regression model was used to analyze the risk factors for death after the surgery. Results A total of 152 children were enrolled, including 70 males and 82 females. Twenty-two patients died with a mean age of 30.73±9.21 d, and the other 130 patients survived with a mean age of 37.62±11.06 d. The Cox analysis showed that younger age (OR=0.551, 95%CI 0.320-0.984, P=0.004), low body weight (OR=0.632, 95%CI 0.313-0.966, P=0.003), large ratio of VSD diameter/aortic root diameter (VSD/AO, OR=2.547, 95%CI 1.095-7.517, P=0.044), long cardiopulmonary bypass time (OR=1.374, 95%CI 1.000-3.227, P=0.038), left ventricular outflow tract obstruction (LVOTO, OR=3.959, 95%CI 1.123-9.268, P=0.015) were independent risk factors for postoperative death. Conclusion For children with IAA and VSD, younger age, low body weight, large ratio of VSD/AO, long cardiopulmonary bypass time and LVOTO are risk factors for death after one-stage radical surgery.

  • Predictive value of varying degrees of delirium on the occurrence of perioperative myocardial infarction following off-pump coronary aortic bypass grafting

    Objective To explore the predictive value of different degrees of delirium after off-pump coronary aortic bypass grafting (OPCABG) for perioperative myocardial infarction (MI). Methods A retrospective analysis was conducted on the clinical data of patients who underwent OPCABG in the First Department of Cardiac Surgery at the First Hospital of Hebei Medical University between April 2018 and March 2024. Patients were divided into a mild delirium group, a moderate delirium group, and a severe delirium group based on the degree of delirium, and into a MI group and a non-MI group based on the occurrence of perioperative MI. Binary logistic regression analysis was used to investigate the predictive factors for secondary MI during OPCABG. The predictive value of different degrees of postoperative delirium for secondary perioperative MI was assessed using receiver operating characteristic (ROC) curves. Results A total of 436 patients were included, with 211 males and 225 females, and a median age of 51 (44.0, 57.75) years. Delirium occurred in 139 patients, with 52 in the mild delirium group, 29 in the moderate delirium group, and 58 in the severe delirium group. MI occurred in 101 patients, with 101 in the MI group and 335 in the non-MI group. Binary logistic regression analysis showed that severe delirium was an independent predictor of secondary MI during OPCABG [OR=23.979, 95% CI (11.572, 49.691), P=0.000]. ROC curve analysis revealed that the area under the ROC curve for predicting perioperative MI by severe postoperative delirium was 0.709, with a sensitivity of 0.546 and a specificity of 0.964. Conclusion Severe postoperative delirium can be used as an indicator to predict secondary MI during OPCABG.

  • Influence of Immunoglobulin on Cellular Immune Function of Postoperative Infants with Cyanotic Congenital Heart Disease

    ObjectiveTo investigate the influence of immunoglobulin (Ig)on celluar immune function of postoperative infants with cyanotic congenital heart disease (CCHD). MethodsForty infants who underwent surgical repair of CCHD in Department of Cardiac Surgery, Children's Hospital of Hebei Province from March to December 2012 were enrolled in this study. All the patients were randomly divided into 2 groups. Patients in Ig group received intravenous Ig treatment at the dosage of 1g/ (kg·day)for 2 days postoperatively in addition to routine therapy. Patients in the control group only received routine therapy without Ig treatment. Five ml venous blood samples of all the patients were taken preoperatively, 0.5 hour and 2 days postoperatively to examine serum levels of interferon gamma (IFN-γ)and interleukin-4 (IL-4)with double-antibody sandwich enzyme-linked immunosorbent assay (ELISA), which were compared between the 2 groups. ResultsThere was no statistical difference in serum levels of IL-4 or IFN-γ preoperatively and at 0.5 hour postoperatively between the 2 groups (P > 0.05). Serum levels of IL-4 and IFN-γ at 0.5 hour postoperatively were significantly higher than preoperative levels in the 2 groups respectively (P=0.000). Serum IL-4 level of Ig group 2 days postoperatively was not statistically different from preoperative level (P=0.362), while serum IL-4 level of the control group 2 days postoperatively was significantly higher than preoperative level (P=0.006). Two days after the operation, serum levels of IL-4 and IFN-γ of Ig group were significantly lower than those of the control group respectively (P=0.039 and 0.007 respectively). Compared with serum levels at 0.5 hour postoperatively in the control group, serum IL-4 level at 2 days postoperatively decreased by 20.08% (P=0.001), and serum IFN-γ increased by 17.80% (P=0.001). Compared with serum levels at 0.5 hour postoperatively in Ig group, serum IL-4 level at 2 days postoperatively decreased by 35.38% (P=0.000), and serum IFN-γ only increased by 7.60% (P=0.143). ConclusionCellular immune function disorder caused by the operation and cardiopulmonary bypass can be effectively improved by postoperative intravenous Ig administration, which may help to reduce postoperative complications.

  • Minimally Invasive Perventricular Ventricular Septal Defect Closure

    ObjectiveTo summarize the experiences of minimally invasive occlusion of ventricular septal defect (VSD) via small chest incision. MethodsWe retrospectively analyzed the clinical data of 131 infants with VSD in Hebei children's Hospital between March 2013 and September 2014, including 83 patients with perimembranous VSD, 24 patients with membranous aneurysm and 24 patients with intracristal VSD. There were 63 males and 68 females with a mean age of 35.28±29.22 months and a mean body weight of 14.56±7.47 kg. Before surgery, a multiple-section transthoracic echocardiography (TTE) was employed to evaluate various parameters of the VSD. Under general anesthesia, a small incision was made to expose the right ventricle. Under TEE guidance, proper device was delivered and deployed to close the defect. Patients also received postoperative following-up by transesophageal echocardiogram (TEE) at regular intervals. ResultsOne hundred twenty-nine patients were successfully performed operation. Two patients were converted to perform traditional surgical closure with cardiopulmonary bypass (cPB). concentric devices were used in 52 patients and eccentric devices were used in 77 patients. During the following-up (1-12 months) period, complications occurred in three patients. Massive pericardial effusion appeared and disappeared after pericardicentesis in one patient. The occlusion device was dislocated in the next day after operation and took out by cPB operation in one patient. There was an asymptomatic residual shunt at 1 mm in one patient. ConclusionThe minimally invasive occlusion of VSD via small chest incision is a safe and effective treatment. It should be encouraged to use in the clinical practice.

  • Curative effect of nitric oxide and bosentan on treatment of the interruption of aortic arch with ventricular septal defect and serious pulmonary hypertension: A randomized controlled study

    Objective To analyze the curative effect of nitric oxide (NO) and bosentan on treatment of the interruption of aortic arch (IAA) with ventricular septal defect (VSD) and serious pulmonary hypertension (SPH). Methods Thirty-two children with IAA and VSD combined SPH from January 2015 to May 2017 confirmed by cardiac CT and ultrasound in Children’s Hospital of Hebei Province were enrolled including 17 males and 15 females, aged 1.10-4.30 months (mean, 2.71±0.98 months) and weighing 3.33-6.10 kg (mean, 4.57±0.88 kg). The 32 children were randomly divided into two groups (n=16 in each), a NO group and a bosentan group. All the patients underwent interruption of aortic arch and ventricular septal defect repair. When patients returned to cardiosurgery intensive care unit (CSICU) half an hour later, patients in the NO group inhaled NO 20 ppm for 36 h and those in the bosentan group were given bosentan by nasogastric feeding 15 mg, twice a day. The cardic index, pulmonary/systemic pressure ratio, oxygenation index at 3 h, 6 h, 12 h, 24 h, 36 h after surgery were evaluated, and the differences between the two groups were compared. Results The pulmonary/systemic pressure ratio in the two groups increased at first and then decreased, while oxygenation index in the two groups decreased at first and then increased, and the differences in the same groups at the adjacent time points were statistically significant (P<0.05). The cardiac index in the two groups decreased at first and then increased, the differences in the same groups at the adjacent time points were statistically significant, except for 6 h and 12 h after surgery in the bosentan group (P>0.05). At postoperative 6 h, 12 h, the oxygenation index in the NO group was significantly higher than that in the bosentan group, and the pulmonary/systemic pressure ratio in the NO group was less than that in the bosentan group (P<0.01). The cardiac index in the NO group was higher than that of the bosentan group after 6 h, 12 h, 24 h of operation, which were statistically significant (P<0.05), and the cardic index of children in the NO group was greatly higher than that in the bosentan group after 12 h of surgery (P<0.01); at the same time point, the corresponding indexes were not statistically significant between the two groups (P>0.05). Conclusion NO inhalation in the treatment of IAA with VSD and SPH in children with early postoperative SPH is better than the bosentan, but in the late postoperative period, the effect is similar.

  • Effect of inhaling NO perioperatively on postoperative cardiac and pulmonary functions in infants with congenital ventricular septal defect complicated with severe pulmonary hypertension: A randomized controlled trial

    Objective To investigate the effect of low-flow inhaling NO for short time on postoperative cardiac and pulmonary functions in infants with congenital ventricular septal defect complicated with severe pulmonary hypertension. Methods Forty-five patients with congenital ventricular septal defect complicated with severe pulmonary hypertension from May 2014 to May 2016 in our hospital were enrolled. There were 19 males and 26 females, whose age ranged from 1 to 22 months (average age: 7.2±14.4 months) and weight ranged from 2.7 to 10.5 kg (average weight: 6.8±3.6 kg). The patients were randomly divided into three groups (n=15 in each): the blank group, the prior inhalation group and the posterior inhalation group. The blank group did not inhale NO, and the prior inhalation group inhalated NO for 10 min after tracheal and intubation. After the opening of the aorta, the posterior inhalation group inhaled NO for 10 min. The concentration of NO was 20 × 10–6. The pressure ratio of pulmonary circulation/systematic circulation, heart index and oxygenation index were calculated and the troponin value of the three groups was monitored 10 min after returning to intensive care unit (ICU) and postoperatively 1 h, 3 h and 24 h. Differences among above indicators between three groups were compared. Results The troponin value of the posterior inhalation group within 3 h increased most, followed by the blank group and the prior inhalation group. Postoperatively 1 h and 3 h, the troponin value of the prior inhalation group was significantly less than that of the blank group and posterior inhalation group (P<0.01) and the value on postoperative 24 h in each group was lower than that on postoperative 3 h. The cardiac index of prior inhalation group was higher than that of the blank group and the posterior inhalation group at each time point. Postoperatively 3 h and 24 has well as 10 min after returning to ICU, the cardiac index in prior inhalation group was significantly higher than that of the posterior inhalation group (P<0.05). The pressure ratio of pulmonary circulation/systematic circulation of posterior inhalation group increased more than that of blank group; the differences in two groups were significant between postoperative 3 h and 10 min after returning to ICU (P<0.01). There was no statistical significance in the pressure ratio on postoperative 24 h and 10 min after returning to ICU (P>0.05) in three groups. The index of oxygenation of the prior inhalation group was higher than that of the blank group and the posterior inhalation group and statistically different from that of posterior inhalation group (P<0.05). Conclusion Inhaling NO 10 min preoperatively can reduce the injury to the heart and lung function effectively, but the result is the opposite when inhalating NO 10 min after aorta opening.
