Objective To evaluate the role of transesophageal echocardiography (TEE) in perioperative period of pediatric patients with congenital heart disease (CHD).Methods From July 2011 to December 2012,TEE was used in 393 pediatric patients(≤ 14 years) with congenital heart disease in perioperative period.We make a retrospective review with the clinical data of these cases.Results Operative schemes or therapeutic schedules of 60 patients(15.3%) were altered according to TEE.By preoperative TEE,the diagnosis of transthoracic echocardiography (TTE) of 4 cases(1.0%) were amended,4 cases (1.0%) were complemented,and 4 cases (1.0%) got the auxiliary diagnosis,among which operative schemes of 11 cases (2.8%)were altered.During the operate,29 cases(7.4%) found residual problems,11 cases(2.8%) got the auxiliary diagnosis.By postoperative TEE,7 cases(1.8%) found residual problems,1 case(0.3%) got the auxiliary diagnosis.Complications occurred in 9 cases(2.3%) of the 393 patients.Oral and pharyngeal mucous membrane bleeding occurred in 7 cases (1.8%),inadvertent tracheal extubation in 2 cases(0.5%).Conclusion TEE plays an important role in confirming preoperative diagnoses,formulating surgical plans,evaluating immediate operative results,identifying patients with residual defects and guiding the therapeutic schedule in perioperative period of pediatric patients with congenital heart disease.

Objective To summarize the clinical experience of surgical intervention for cardiac neoplasm in a fetus . Methods A 32-year-old pregnant woman was admitted to our hospital for complaint of fetal cardiac neoplasm .A separated het-erogenic cardiac occupying lesion was identigied at right atrium of the fetus by echocardiography , whose size is 2.85 cm ×2.25 cm, but the pathogenic origin still remained uncertain, maybe originate from ether pericardium or atrium.The annulus of tri-cuspid valve was compressed nearly 50% with the presence of amount of pericardial effusion.The fetal heart rate decreased at some fetal position resulting in the compression to the heart.So an Ex-utero Intrapartum Therapy(EXIT) procedure was per-formed under the supply of placenta at the 32 weeks of pregnancy.Cesarean section was performed with intact umbilicus and fe-tal circulation by obstetricians.Consequently, the median sternotomy of this fetus and pericardiotomy were performed , with 30 ml clear pericardial effusion drained .The tumor was confirmed to be giant right atrial neoplasm after the intraoperative explora-tion.Considering on the high risk of the cardiopulmonary bypass and limited time for EXIT , the giant atrial neoplasm was left alone with delayed sternum closure after the effectively decompression of the heart .The omphalotomy was successfully per-formed after the EXIT surgery.The neoplasm resection and the repair for its defect on right atrium were performed with cardiop-ulmonary bypass 2 days later.Results Convalesce of this mother was quite good after cesarean resetion .Hemodynamics of the premature baby was satisfatory after the resection of right atrial neoplasm which pathological report was benign hemangioma . Conclusion Via multiple disciplines collaboration , EXIT intervention for fetus is feasible and safe under adequate prepara-tion.

OBJECTIVETo summarize anesthetic management of low birth weight infants undergoing surgical intervention of congenital heart disease without cardiopulmonary bypass.
METHODSFifty-three low birth weight infants (including 49 premature infants) with congenital heart disease underwent surgical treatment without cardiopulmonary bypass during the period from June, 2003 to July, 2013. The mean gestational age of the infants was 30.96∓3.09 weeks (26-40 weeks) with a mean age on the operation day of 32.81∓20.76 days (4-87 days), birth weight of 1429.90∓455.08 g (640-2460 g), and weight on the operation day of 1750.20∓481.59 g (650-2460 g). All the infants underwent cardiac operations without cardiopulmonary bypass under general anesthesia. The respiratory parameters and acid-base and electrolyte balance were adjusted according to blood gas analysis. The inotropic drug was used to maintain the hemodynamic stability.
RESULTSForty-seven of the infants received patent ductus arteriosus (PDA) ligation. Of these infants, 1 had cardiac arrest before the operation with failed cardiopulmonary resuscitation, and in another case, PDA ligation was aborted due to severe hypoplasia of the aortic valve and ascending aorta found intraoperatively by transesophageal echocardiography. Two infants underwent coarctation of the aorta (CoA), and 1 of them died during the operation due to cardiac arrest. The total mortality of these infants was 3.77% and the early postoperative mortality (<72 h) was 5.66%.
CONCLUSIONSNon-cardiopulmonary bypass surgery can be performed in low birth weight infants in early stage, and effective anesthetic management can reduce the perioperative mortality and improve the postoperative survival rate.

Objective To analyze the early outcomes of 203 neonates with low birth weight (<2 500 g) undergoing cardiac surgery, and to analyze the causes of death during hospitalization. Methods From June 2003 to June 2017, medical records of 203 neonates with low birth weight undergoing congenital heart surgery in Guangdong General Hospital were reviewed retrospectively. There were 124 males and 79 females, including 151 premature infants. The average birth weight was 1 719±515 g, the average age at operation was 32.7±20.2 d and the average weight at operation was 1 994±486 g. The causes of death during hospitalization (including neonates given up on treatments) were analyzed. Results Totally 103 patients had pneumonia, 98 patients needed mechanical ventilation to support breathing and 26 patients needed emergency operation before operation. All patients undergoing congenital heart surgery were treated with general anesthesia with tracheal intubation, including 107 patients under non cardiopulmonary bypass (CPB) and 96 patients under CPB with a mean CPB time of 96.5±71.7 min and a mean aorta cross-clamp time of 51.8±45.5 min. The average postoperative mechanical ventilation time was 9.1±21.5 d and the average postoperative length of stay was 26.7±19.3 d. The major postoperative complications included pneumonia, anemia, atelectasis, septicemia, intrapleural hemorrhage, diaphragm paralysis and cardiac dysfunction. Twenty-nine patients died during hospitalization and the overall mortality rate was 14.3%. Four patients died in the operation room, 14 patients died 72 hours after operation and 2 patients were given up. The main causes of hospitalized death were low cardiac output syndrome, severe infection, disseminated intravascular coagulation disorder, acute renal failure and pulmonary hypertension crisis. Conclusion Overall, early cardiac surgery for low birth weight neonates is safe and effective. The difficulty of the cardiac surgery is the key to the prognosis. Strengthening perioperative management can improve the quality of operation and reduce the risk of mortality and morbidity during hospitalization.
