目的：探讨彩色多普勒超声在心脏手术中的应用价值。方法：在14例心脏病手术中，于心脏修复完成后经心外膜超声检查。结果：一例先天性心脏病室间隔缺损修补片周少量残余漏；一例风湿性心脏病二尖瓣、主动脉瓣置换术后，主动脉瓣下少量返流；因不构成血流动力学的改变，未行二次修复。结论：可即时、准确地为外科医生提供相关信息，评价手术效果。
目的:观察、比较七氟醚吸入麻醉与全凭静脉麻醉在小儿先天性心脏病手术中的应用。方法: 40例择期行先天性心脏病房室缺矫治术患儿,随机分为七氟醚组和全凭静脉麻醉组(TIVA组),每组各20例。七氟醚组患儿以七氟醚吸入诱导,复合小剂量芬太尼、咪达唑仑、维库溴铵,麻醉维持为七氟醚吸入+芬太尼、维库溴铵;静脉组患儿肌注氯胺酮后,以芬太尼、咪达唑仑、维库溴铵诱导,维持使用丙泊酚持续泵入+芬太尼、维库溴铵。比较两组术中各时点血流动力学变化、手术麻醉时间与芬太尼、维库溴铵用量、术后呼吸支持时间、清醒时间、拔管时间,比较两组不良反应发生情况。结果: 两组患儿均维持比较稳定的血流动力学状态。七氟醚组芬太尼与维库溴铵用量明显低于TIVA组,呼吸支持时间、清醒时间、拔管时间明显低于TIVA组。七氟醚组2例术后发生躁动,3例发生恶心,稍高于TIVA组。结论: 七氟醚应用于小儿先心房室缺矫治术,可提供稳定的血流动力学状态,并降低芬太尼与肌松剂用量,实现术后早拔管、改善患者预后、降低医疗费用。
ObjectiveTo 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.MethodsFrom 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.ResultsTotally 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.ConclusionOverall, 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.
