ABSTRACT
Objective:To evaluate the value of sugammadex for ultra-fast-track anesthesia in pediatric patients undergoing surgery for correction of congenital heart disease.Methods:Forty pediatric patients of both sexes, aged 1-6 yr, with American Society of Anesthesiologists physical status Ⅱ, scheduled for elective surgery for correction of congenital heart disease, were enrolled in this study and randomly assigned into sugammadex group (group S) and control group (group C) with a random number table.Sugammadex 4.0 mg/kg was injected intravenously to reverse neuromuscular relaxation in group S and the equal volume of normal saline was administrated in group C when the train-of-four (TOF) count was 0 and post-tetanic count was 1 or 2 during recovery from anesthesia.The recovery time of TOF ratio to 25%, 75% and 90%, the extubation time and the success rate of ultra-fast-track anesthesia were recorded.Results:Compared to group C, sugammadex significantly shortened the recovery time of TOF ratio to 25%, 75% and 90% and the extubation time in group S ( P<0.05); Furthermore, the success rate of ultra-fast-track anesthesia reached 100% in group S compared to 0% in group C. Conclusion:Intravenous administration of sugammadex 4.0 mg/kg significantly shortens the recovery time of neuromuscular relaxation and extubation time and enhances the success rate of ultra-fast-track anesthesia in pediatric patients undergoing surgical correction of congenital heart disease.
ABSTRACT
Objective:To analyze and clarify the causes, types, risk factors and treatment principles of early postoperative tachycardia in children with congenital heart disease.Methods:A retrospective analysis of the clinical data of 2 126 children with primary radical congenital heart surgical procedure in Shanghai Children′s Hospital from January 2014 to December 2020, including 1 322 cases of ventricular septal defect or ventricular septal defect combined with atrial septal defect, 421 cases of atrial septal defect, 194 cases of tetralogy of Fallot, D-transposition of the great artery or double outlets of right ventricle combined with pulmonary stenosis, and 189 cases of other complex congenital heart disease. The surgical method is a median sternal skin incision or a small right axillary skin incision, and cardiopulmonary bypass is established routinely. The age, body mass, disease type, cardiopulmonary bypass and aortic occlusion time, vasoactive drug use, ECG monitoring and other indexes were observed and monitored.Results:There are 425 cases of early postoperative tachycardia in 2 126 children with congenital heart disease, with an incidence of 20.0%. The incidences of sinus tachycardia, borderline ectopic tachycardia, atrial tachycardia and ventricular tachycardia were 14.8%(314/2 126), 4.5%(96/2 126), 0.8%(17/2 126) and 0.5%(10/2 126), respectively. Logistic regression analysis revealed that the low age ( OR=1.98, 95% CI: 1.25-2.65, P<0.01), low weight ( OR=2.35, 95% CI:1.86-2.75, P<0.01), large ventricular septal defect ( OR=1.56, 95% CI:1.09-2.06, P=0.02), complex congenital heart disease ( OR=2.03, 95% CI: 1.57-2.52, P<0.01), long duration of cardiopulmonary bypass ( OR=1.77, 95% CI: 1.23-2.28, P<0.01), long aortic cross-clamp time ( OR=1.89, 95% CI:1.20-2.55, P<0.01), acidosis ( OR=1.63, 95% CI:1.11-2.14, P<0.01), and the combination usage of vasoactive drugs ( OR=1.86, 95% CI:1.23-2.48, P<0.01) were significantly associated with the occurrence of early postoperative tachycardias. Conclusion:This study has important clinical guiding value for predicting early postoperative tachycardia in children with congenital heart disease, clarifying its causes and types, and timely handling, so as to improve the postoperative survival rate of children.
ABSTRACT
@#Objective To study the safety of right vertical infra-axillary thoracotomy (RVIAT) in the repair of ventricular septal defect (VSD) and the optimal age for RVIAT. Methods Between June 2014 and June 2018, 441 children underwent VSD repair via RVIAT in our hospital. According to the age, they were divided into four groups: a 4 months to 1 year old group (R1 group, n=123), a 1-2 years old group (R2 group, n=106), a 2-5 years old group (R3 group, n=166), a >5 years old group (R4 group, n=46). The clinical effects of the patients were compared. Results All the operations were successfully performed and no serious complication was found in all groups. No statistical difference was observed in the operation time, blood loss during operation, thoracic drainage 24 h after operation among groups (P>0.05). The cardiopulmonary bypass time, aortic cross-blocking time and ICU stay time in the R1 and R2 groups were longer than those in the R3 and R4 groups (P<0.05). In the R1 group, the postoperative ventilating time and postoperative hospital stay time were longer, and the blood transfusion volume was more than those in the R3 and R4 groups (P<0.05). The incidence of postoperative complications was higher in the R4 group than that in the R1 and R3 groups (P<0.05). Conclusion VSD repair via RVIAT may be more effective in children >2 years old, and 2-5 years old may be the optimal age.
ABSTRACT
Objective To investigate the clinical features and prognostic factors of children with gigantic thoracic tumors.Methods Clinical data were collected from the database of Cardiothoracic Surgery,Shanghai Children's Hospital between January 2009 and June 2015.The analyses were mainly focused on the clinical data of 76 cases of thoracic giant tumor that underwent surgical treatment,Univariate survival analysis was performed with Kaplan Meier method.Results Pathological results showed that 35 cases were benign tumors and 41 cases were malignant tumors.For benign tumors,the main pathological classification were ganglioneuroma in 12 cases,vascular tumors in 9 cases,germ cell tumors in 8 cases.For malignant tumors,the main pathological classification were neuroblastoma in 13 cases,ganglioneuroblastoma in 7 cases and lymphoma in 7 cases,etc.After surgical resection 31 cases of benign tumors were long-term survival.The 5 year survival rates of 70 patients with gigantic thoracic tumors was more than 75％,39 patients with malignant tumors were more than 50％.Single factor in Kaplan Meier analysis showed that gender,location of primary tumor were not associated with neurogenic tumor prognosis(P ＞ 0.05).The age of patients,tumor stage,tumor pathological type,whether chemotherapy are associated with prognosis of neurogenic tumors the difference has statistical significance (P ＜ 0.05).Conclusion Surgical resection is a prognostic factor for patients with benign thoracic giant tumor.The recurrence and metastasis rates of malignant tumor is high.Its prognosis is poor.The survival time of patients with postoperative chemotherapy or radiotherapy can be prolonged.The most common children gigantic thoracic tumors are neurogenic tumors,There is no correlation between the prognosis of neurogenic tumors and sex or primary site.While age,tumor stage,pathology and whether with chemotherapy are associated with neurogenic tumor prognosis.
ABSTRACT
The pulmonary artery sling (PAS)is a rare congenital cardiovascular disease and usually associated with airway stenosis and cardiovascular anomalies. Abnormal left pulmonary artery oppress trachea and esophagus can cause respiratory tract obstruction or esophageal compression symptoms,such as recurrent wheezing,cough,lung infec-tions,difficulty of breathing or swallowing. Once diagnosed,the patients has surgical indications,but due to the lack of specific clinical manifestations,missed diagnosis or misdiagnosis for other respiratory diseases may occur. The surgical method of PAS is mainly the left pulmonary transplantation,whether perform tracheoplasty remains controversial.
ABSTRACT
Objective To investigate the complications and management of nitinol self-expandable metal stent (cSEMS) in treatment of refractory esophageal strictures in children. Methods The clinical data were reviewed for 9 pediatric patients with refractory benign esophageal disorders from May 2009 to December 2016, specially designed cSEMS were applied to them, data about effects and complications were collected during regular follow-ups. Results Successful cSEMS placement was performed in 9 children, the symptom of dysphagia was obviously alleviated after implantation, all patients underwent vomiting and chest pain 1~7 days after operation; 1 case could not put up with the pain, so the stent had to be removed in 36 hours after implantation; 2 cases developed a recurrent stricture within 3 months after stent removal, growth of mild granulation tissue was found in 1 case; In the case with esophageal fistulas, migration and poor adherence to the esophagus was occurred in 3 days after implantation, then a new designed cSEMS with bigger proximal tip was planted in the same place 1 week later, 2 months after stent removed, fistula was healed. Conclusion Placement of cSEMS is safe and effective in treating pediatric patients with refractory esophageal stricture. However, complications associated with stent placement should not be ignored, individually designed stent and timely management of the complications are quite important in order to enhance clinical efficacy.
ABSTRACT
Objective To discuss the types,pathogenesis and treatment of early cardiac arrhyth-mias in infants after open heart surgery with congenital heart diseases. Methods 992 infants after open heart surgeries were divided into control group and arrhythmia group. Another junctionalectopictachycardia ( JET)group was separated from arrhythmia group. Various preoperative and postoperative data were com-pared. Results 197 infants suffered from cardiac arrhythmia within 3 days right after open heart surger-ies. After exactly the same surgery procedures,JET group was significantly different with control group in aortic cross-clamp time,cardiopulmonary bypass time and stay in CICU(p<0. 05). As for time of ventila-tion,no significant difference was found between the two groups. Conclusion Early diagnosis and treat-ment of cardiac arrhythmia can not only improve the success rate of open heart surgery,but also promote early recovery.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the new biomarkers of acute kidney injury, as well as to confirm the values of response gene to complement 32 (RGC-32) for early diagnosis of acute kidney injury by comparing the values of serum creatinine (Scr) and cystatin C (CysC) in children who had undergone cardiopulmonary bypass (CPB).</p><p><b>METHOD</b>Sixty-seven patients who had accepted CPB were recruited from the cardiac surgery intensive care unit, Children's Hospital Affiliated to Shanghai Jiao Tong University from March to June 2013 and assigned to acute kidney injury group (group AKI) or non-acute kidney injury group (group non-AKI), on the basis of the definition by the pediatric RIFLE (pRIFLE) criteria. Also 30 healthy control children were recruited. Serum samples were taken regularly from each patient after CPB at 30 min, 2 h, 4 h, 24 h, 48 h and 72 h for RGC-32. Serum samples were tested by enzyme linked immunosorbent assay (ELISA) which was employed to determine the levels of serum RGC-32. Scr and CysC were analyzed by HITACHI 7180 automatic biochemical analyzer. All the data were analyzed by receiver operator characteristic curve (ROC) and area under curve (AUC).</p><p><b>RESULT</b>The incidence of AKI was 34% (23/67), including 15 cases with risk stage AKI, 4 cases with injury stage AKI, 3 cases with failure stage AKI, 1 cases with loss stage AKI. Three out of four subjects with Failure stage AKI and the one case with Loss stage all accepted renal replacement therapy. CPB group had a higher level of serum RGC-32 than that of pre-operation after CPB 30 minute [(2.88 ± 0.68) µg/L vs. (1.39 ± 0.31) µg/L, P < 0.05]. At the same time, comparing with the non-AKI group, the levels of serum RGC-32 were higher than that of controls 30 min, 2 h, 4 h, 24 h and 48 h after CPB (t = 2.560, 2.180, 2.818, 2.226, 3.017; P < 0.05). The values for the AUC were determined for RGC-32 as 0.770, 0.707, 0.768, 0.728,0.723 and 0.770 after CPB 30 min, 2 h, 4 h, 24 h, 48 h and 72 h. The values for sensitivity of serum RGC-32 30 min, 2 h and 4 h after CPB was 0.914, 0.824, 0.824 and the values for specificity of serum RGC-32 was 0.619, 0.667, 0.810, respectively. But the values for sensitivity of CysC was 0.625, 0.813, 0.813, and specificity 0.571, 0.619, 0.571, respectively. The values for sensitivity of Scr was 0.625, 0.625, 0.813 and specificity was 0.571, 0.571, 0.524, respectively.</p><p><b>CONCLUSION</b>The sensitivity of serum RGC-32 for detecting AKI was much higher than that of Scr and serum CysC in children who had accepted CPB, and that RGC-32 may be a new biomarker for early detection of AKI. However, the conclusion needs to be further elucidated.</p>

Objective To investigate the values of urine neutrophil gelatinase associated lipocalin (NGAL), kidney injury molecular-1 (KIM-1) and interleukin-18 (IL-18) in the diagnosis of acute kidney injury (AKI) in children after cardiopulmonary by-pass (CPB). Methods Sixty-seven patients who had undergone CPB were recruited from March to June 2013 and assigned to acute kidney injury group (AKI group) or non-acute kidney injury group (non-AKI group) according to the pediatric RIFLE (pRIFLE) cri-teria. Serum and urine samples were collected from each patient at 30 min, 2 h, 4 h, 24 h, 48 h and 72 h after CPB for serum and urine creatinine, urine NGAL, KIM-1 and IL-18. All the data were evaluated by receiver operator characteristic curve (ROC) analysis and area under curve (AUC) analysis. Results Twenty-three cases (34.3%) had AKI in 67 children after CPB. Among them 15 cases were risk-stage AKI, 4 cases injury-stage AKI, 3 cases failure-stage AKI and 1 cases loss-stage AKI. The levels of urine NGAL/Ucr were higher in AKI group than those in non-AKI group at 4h, 48h and 72h after CPB (P<0.05). The cut-off value of NGAL/Ucr was 1.200 at 4 h after CPB, the sensitivity and specificity for prediction of AKI were 0.864 and 0.561, and the AUC was 0.671 (95%CI:0.537-0.804). The levels of urine KIM-1/Ucr were higher in AKI group than those in non-AKI group at 48h and 72 h after CPB (P<0.05). The cut-off value of KIM-1/Ucr was 1.162 at 24h after CPB, the sensitivity and specificity for prediction of AKI were 0.773 and 0.512, and the AUC was 0.698 (95%CI:0.563-0.834). The levels of IL-18/Ucr were higher in AKI group than those in non-AKI group at 4 h after CPB (P<0.05). The cut-off value of IL-18/Ucr was 0.04 at 4 h after CPB, the sensitivity and specificity for predici-ton of AKI were 0.773 and 0.561, and the AUC was 0.655 (95%CI:0.510-0.800). Conclusions It is indicated that urine NGAL, KIM-1 and IL-18 may have important clinical values for early prediction of AKI.

ABSTRACT
Ovbective To evaluate the outcome of the complete repair for critical and complex congenital heart defects in small infants with cardiopulmonary bypass. Methods A retrospective review of hospital records was performed for 187 infants under 6 months undergone cardiac operation from January 2000 to January 2004. Average age was (4.15?2.32) months (3d-6months) and average weight was (4.42?0.56)kg (3～7kg). The diagnoses included ventricular septal defect with pulmonary hypertension,transposition of the great arteries,aortic coarctation with other lesions,total anomalous pulmonary venous connection,tetralogy of Fallot,atrioventricular canal defect,pulmonary atresia,and neonatal cardiac tumor. Average duration of mechanical ventilation was (17.5?9.7) hours. ICU stay was (4.9?1.5) days. Results 9 cases died after operation with a hospital mortality of 4.81%. Postoperative complications included low cardiac output syndrome,residual shunt,pulmonary infection and pulmonary hemorrhage. 178 are alive and in good cardiac status at follow-up of 4～48 months. After repair,growth approximates the normal. Conclusion With the development of pediatric cardiac surgery, cardiac operation with CPB in small infants with critical and complex congenital heart defects is feasible and may provide satisfactory survival.
