To compare the postoperative outcome according to the type of anesthesia, formerly prematured and high-risk infants who had received and weaned ventilator care preoperatively and had undergone inguinal herniorrhaphy were enrolled in this study. Immediate pre- and post-operative respiratory data which contained the lowest respiratory rates, SpO2, heart rates and the incidence of hypoxemia and bradycardia were collected with the incidence of ventilator care, application of continuous positive airway pressure (CPAP), application of oxygen, hospital stay, and respiratory mortality by chart review, retrospectively. Among the twenty-nine infants, fourteen received the general anesthesia (GA group), and fifteen received the spinal anesthesia (SA group). Postoperatively, the infants in the GA group had lower SpO2 (77.1 +/- 20.9% vs. 93.0 +/- 5.5%), higher incidence of hypoxemia (6 vs. 0), ventilator care (5 vs. 0) and application of CPAP (4 vs. 0) than the infants in the SA group. One infant in the GA group died because of acute respiratory failure caused by respiratory syncythial virus pneumonia. We concluded that spinal anesthesia reduces postoperative oxygen desaturation and respiratory morbidity in formerly prematured and high-risk infants who underwent inguinal herniorrhaphy.

Sick sinus syndrome (SSS) is a disorder characterized by sinus node dysfunction. Although the condition is most common in the elderly, it can occur in children including neonates and its recognition and treatment are important. The diagnosis of SSS is based on the presence of sinus bradycardia, sinus arrest or exit block, combinations of sinoatrial and atrioventricular nodal conduction disturbances, and atrial tachyarrhythmias documented in the Holter recordings. In most children with SSS, previous history of congenital heart malformation or cardiac surgery is noted. SSS is also seen in the children including neonates without heart disease or other contributing factors, however SSS is most often idiopathic. The treatment of SSS depends on the basic rhythm problem, but generally involves the placement of a cardiac pacemaker. We report a case of SSS in extremely low birth weight infant without congenital heart disease and suggest that the treatment system is necessary for preterm infants with SSS.

Even though some authors have reported on the advantages of early total correction of complex heart disease, for low birth weight premature neonates, most surgeons prefer a multi-step approach to early total correction due to the many problems, such as the technical problems, the cardiopulmonary bypass management and etc. We report here on a successful case of early one-stage total repair of coarctation of the aorta and a ventricular septal defect in a 1,250 gram premature neonate.

OBJECTIVETo study the treatment and prognosis of pulmonary hemorrhage in preterm infants.

METHODSA total of 106 preterm infants diagnosed with pulmonary hemorrhage, who were hospitalized in the neonatal ward of Peking University Third Hospital between 2007 and 2016, were enrolled. These patients were divided into 2007-2011 group (34 cases) and 2012-2016 group (72 cases) according to the time of hospitalization, divided into conventional-frequency ventilation group (43 cases) and high-frequency oscillatory ventilation (HFOV) group (63 cases) according to the respiratory support method used after the development of pulmonary hemorrhage, and divided into non-operation group (34 cases) and operation group (14 cases) according to whether PDA ligation was performed for the unclosed PDA before pulmonary hemorrhage. The general data, treatment, and prognosis were compared between different groups.

RESULTSCompared with the 2007-2011 group, the 2012-2016 group had higher rates of HFOV and PDA ligation (P<0.05), a lower mortality rate during hospitalization (P<0.05), a longer length of hospital stay (P<0.05), and higher incidence rates of intracranial hemorrhage and bronchopulmonary dysplasia (P<0.05). Compared with the conventional-frequency ventilation group, the HFOV group had a lower mortality rate during hospitalization (P<0.05), a longer length of hospital stay (P<0.05), and higher incidence rates of intracranial hemorrhage and bronchopulmonary dysplasia (P<0.05). Compared with the non-operation group, the operation group had a lower mortality rate during hospitalization (P<0.05), a longer length of hospital stay (P<0.05), and higher incidence rates of intracranial hemorrhage and bronchopulmonary dysplasia (P<0.05).

CONCLUSIONSThe application of HFOV and PDA ligation can improve the survival rate of preterm infants with pulmonary hemorrhage, but the incidence of intracranial hemorrhage and bronchopulmonary dysplasia is also increased.

OBJECTIVETo improve the understanding of recognizing and diagnosis of neonatal necrotizing enterocolitis (NEC), imaging assessment of neonates with NEC was analyzed retrospectively.

METHODData of 211 cases of NEC were retrospectively collected from the Department of Neonatology, Children's Hospital of Chongqing Medical University between Jan.1(st) 2006-Dec.31(st) 2011.

RESULTAnalysis of abdominal X-ray of 211 cases showed that there were 40 cases (19.0%) who had no changes on each X-ray, 47 cases (22.3%) had improvement and 23 cases (10.9%) became worse. In the group of no changes, positive rate with good prognosis was 97.5% and with poor prognosis, it was 2.5%. In the group of improvement, positive rate with good prognosis was 97.9%, and the contrary was 2.1%. Positive rate with good prognosis was 56.5%, and the contrary was 43.5% in worse group. Chi-square analysis of the three groups showed χ(2) = 31.742, P < 0.01. Comparison of detection rate of pneumoperitoneum on abdominal X-ray (16.0%, 12/75) and Doppler US (1.3%, 1/75), χ(2) = 10.191, P < 0.05, portal pneumatosis on abdominal X-ray(1.3%, 1/75) versus Doppler US (12.0%,9/75), χ(2) = 6.857, P < 0.05. Surgical timing mostly corresponded to pneumoperitoneum (OR = 19.543) and intestinal obstruction (OR = 19.527) of abdominal X-ray. The logistic regression equation is y = -2.915-1.588x1+2.972x4+2.973x7 + 1.711x9 (χ(2) = 101.705, P < 0.01).

CONCLUSIONAbdominal X-ray is the most important method of diagnosis of NEC, the group of deterioration of abdominal X-ray has obvious bad prognosis differ from no change group and better group. Comparison with abdominal X-ray and Doppler US, the former in pneumoperitoneum positive rate was higher than the latter, at the same time, portal pneumatosis on Doppler US is more sensitive to abdominal X-ray, the value of two imaging assessments both supplement each other. Surgical timing mostly corresponds to pneumoperitoneum and intestinal obstruction.

OBJECTIVES: The aims of the study show the effect of cardiac disease of pregnant women on the perinatal complications and pregnancy outcomes. METHODS: From Jan. 2001 to Nov. 2005, 29 cases of pregnant women with cardiac disease were enrolled and classified by the NYHA (New York Heart Association) classes under the supervision of cardiologist and cardiothoracic surgeon. The average age of all cases is 29.9 years olds and it consists of 13 primigravida and 16 multigravida. For the examination of cardiac function during the pregnancy, the echocardiography was performed. We evaluated the cardiac disease of pregnant woman with the underlying causes, clinical manifestations during the pregnancy, delivery mode, gestational age at birth, birth weight, Apgar score and perinatal complication. RESULTS: All 29 cases with cardiac diseases are composed of 21 cases of NYHA class I (72.7%), 4 case of NYHA class II (13.7%) and 4 cases of NYHA class III (13.7%). There are 11 cases with congenital heart disease (37.9%), 6 cases with acquired heart disease (20.6%), 9 cases with arrhythmia (31.0%), and 3 cases with other cardiac disease (10.3%). Before the pregnancy, 6 cases of 11 cases with congenital heart disease and 5 cases of 6 cases with acquired heart disease performed the corrected cardiac surgery. Echocardiography was performed on 24 cases. It showed average ejection fraction in left ventricle of NYHA class I (13 cases) and NYHA class II, III (8 cases) were 61.5% and 52.6%, respectively. 7 cases of NYHA class I and 1 case of class II was done on the vaginal delivery. 14 cases of class I pregnant woman were performed the cesarean section according to obstetric indications but 3 cases of class II were performed the cesarean section for the prevention of cardiac risks. 4 cases of class III were performed the cesarean section according to obstetrics indications (2 cases) and for the prevention of cardiac risks (2 cases). For gestational age at birth, the average of NYHA class I was 38.1 weeks and the average of NYHA class II, III was 35.4 weeks. The average birth weight showed 3,022 gm in class I and 2,446 gm in class II and class III. Preterm birth were 3 cases (class II; 1 case, class III ; 2 cases). Low birth weight infant were 5 cases (class I; 3 cases, class II 2 cases). Intrauterine fetal death was a case (class I). Congenital abnormalities at birth were not observed in our study. Although no maternal mortality was observed, 2 cases of pulmonary edema caused by cardiomyopathy in NYHA class III and 1 case of Eisenmenger Syndrome caused by PDA in NYHA class II were developed during the labor. CONCLUSION: In this study, the majority of pregnant women with cardiac disease had the congenital heart diseases. It also showed that they can expect good perinatal outcomes by the adequate prenatal care including cardiac surgery before the pregnancy.
