ObjectiveTo explore the effect of comfort care on patients undergoing CT enhanced scan. MethodsSixty patients undergoing CT enhanced scan were enrolled in June 2013, who were randomly divided into general care group (n=30) and comfort care group (n=30). General care group was given the routine care, while patients in the comfort care group accepted comfort care as well as routine care. The success rate of examination and excellent or good imaging rate between the two groups were compared. ResultsIn the general care group, the scan was successful in 21 patients and failed in 9, with a successful scan rate of 70.0% (21/30), and the excellent and good imaging rate was 71.4%. For the comfort care group, the scan examination succeeded in 29 patients and failed in 1 with a success rate of 96.7% (29/30), and the excellent and good imaging rate was 96.6% (28/29). The success rate in the two groups had statistical significance (χ2=7.680, P=0.006), and the excellent and good imaging rate was also significantly different (χ2=7.607, P=0.022). ConclusionComfort care for patients undergoing CT enhanced scan has a good effect in alleviating psychological stress, ensuring comfort and safety, and improving the success rate and excellent and good rate of imaging quality, which reflects its real value of nursing service in CT Department.
ObjectiveTo explore the clinical effect of delayed sternal closure (DSC) after neonatal cardiac operations. MethodsWe retrospectively analyzed the clinical data of 347 neonates who underwent cardiac operations through midterm sternotomy in Shanghai Children's Medical Center between January 2008 and December 2012. There were 273 male and 74 female patients with mean age of 14.8±8.4 days and mean weight at 3.4±0.5 kg. We analyzed the influencing factors of delayed sternal closure and the relationship between delayed sternal closure and mortality. A total of 127 patients had DSC (36.6%). Ninety-two patients were of primary DSC because of hemodynamic instability in the operation room, and 35 were of the secondary DSC because that the sternum was reopened in intensive care unit during the early postoperative period. The diagnosis of complex congenital heart defects had a high risk of DSC. The incidence of DSC for great artery (TGA), corctation of aorta (CoA), interruption of aortic arch (IAA), total anormalous pulmonary vein drainage (TAPVD), Taussig-Bing malformation, hypoplastic left heart syndrome (HLHS) was 43.2%, 83.3%, 62.5%, 15.6%, 71.4%, and 66.7% respectively. The DSC patients had longer duration of CPB time (141.4±51.7 min versus 108.5±51.9 min) and clamping time (79.3±29.2 min versus 65.4±25.5 min). In 113 patients the sternums were closed 1-11 days after the initial operation. Sixteen patients died ultimately including 2 deaths after the closure of sternum with a mortality of 12.6%. Surgical site infection occurred in 5 patients including 2 severe patients with surgical intervention. ConclusionDSC has been an essential part of neonatal heart surgery. It provides an opportunity for the recovery of cardiac function.
ObjectiveTo evaluate the performance and safety of a novel device for left atrial appengdage (LAA) closure in dogs. MethodsThrough the fourth left intercostal, the LAA clips were implanted at the base of LAA in six dogs. Macroscopic pathology, histopathology and biological detection were performed at 7 d, 60 d, 90 d, 180 d after implan-tation respectively. ResultsThe devices were all successfully implanted at the base of LAA. There is no transposition of the LAA clips. Complete fibrosis and atrophy of LAA occurred at 60 d after implantation. LAA closure was completed with a new endothelial tissue layer developed on the occluded orifice of the left atrium after 60 d after implantation. The level of atrial natriuretic peptide did not decrease significantly after the device implantation (275.64±60.00 pg/ml vs. 248.34±56.10 pg/ml, P=0.529). ConclusionThe novel device for LAA closure achieved easy, reliable and safe closure of the LAA in canine model.
ObjectiveTo summarize the cardiac-vascular abnormalities and clinical results in patients with Fontan operation for heterotaxy syndrome. MethodWe retrospectively analyzed the medical records of 81 patients who underwent the Fontan operation with heterotaxy syndrome between September 2008 and September 2013. There were 49 male and 32 female patients at age of 3.79 (range 2.07-13.02) years with preoperative room air saturation of 81% (range 63%-97%) and weight of 14.8 (10.0-36.0) kg. ResultsThere were 70 patients in the right atrial isomerism group and left in 11 patients. Dextrocardia was seen in 16 patients, and single atrium in 50 patients. Single ventricle was found in 44 patients, conotruncal defects in 40 patients, pulmonary stenosis in 72 patients, pulmonray atresia in 8 patients, common atrioventricular valve in 61 patients, and bilateral superior vena cava in 54 patients. The staged Fontan procedure was applied in 57 patients and one stage in 24 patients. Operation strategies were included intra/extracardiac conduit (n=17), extracardiac conduit (n=48), lateral tunnel (n=14) and direct cavopulmonray connection (n=2).There were 15 early deaths. Postoperative complications included low cardiac output in 15 patients, hepatic insufficiency in 35 patients, renal insufficiency in 55 patients required peritoneal dialysis and arrhythmia in 28 patients. The room air saturation was 89% (range 78%-98%) before discharge and time of follow-up was from 2 months to 6 years in 64 patients. Thromboembolic events were found in 2 patients who had accomplished conduit replacement operation. ConclusionCompared with reported literatures in western countries, heteraotaxia patients are mostly with right atrial isomerism. Fontan palliation is still the main treatment option and strict indication was needed for satisfactory clinical results.
Objective To summarize our clinical experience of side-slide tracheoplasty in surgical management of bridging bronchus associated with congenital tracheal stenosis(CTS) and congenital heart disease (CHD). Method We retrospectively analyzed the clinical data of 8 bridging bronchus patients associated with CTS and CHD underwent tracheoplasty in our hospital from January 2010 through June 2015. There were 3 males and 5 females at age of 19.6±9.1 months and weight of 9.9±5.4 kg in our hospital. It was found that main tracheal associated with intermediate bronchus stenosis in 4 patients. Complete tracheal rings or bronchial rings were identified in all cases. Less than 50% normal tracheal size was found in all patients. Correction of CHD and tracheoplasty were done under cardiopulmonary bypass at the same stage. The technique of side-slide tracheoplasty was used in all patients. Results Average cardiopulmonary bypass time was 64.0±24.1 min. Average aortic clamp time was 14.0±18.1 min. No operative death occurred in hospital. The average duration of postoperative hospital stay was 20 d. Follow-up was completed in 8 patients. The duration of follow-up was 1 month to 5 years. Tracheal granulation occurred in one patient after six weeks of postoperation. The clinical symptoms improved significantly in the remaining patients. Conclusions Bridging bronchi has special anatomical features. The technique of side-slide tracheoplasty can be used to correct bridging bronchus associated with CTS with satisfactory outcomes.
ObjectiveTo analyze the outcomes of patients with one-stage Fontan procedure and short-term prognosis at a single institute. Method We retrospectively analyzed clinical records of 116 patients with one-stage Fontan procedure in our hospital from January 2008 through September 2013. There were 77 males and 39 females (36%), with median age 6.27 years (ranged 3.15 to 17.47 years) at the time of surgery and the median weight at 17.5 kg (ranged 10.0 to 80.0 kg). There were 55 patients with standard extracardiac conduit, 13 patients with direct extracardiac connection, 17 patients with intra-atrial or intra/extracardiac conduit, and 31 patients with lateral tunnel. ResultsMedian cardiopulmonary bypass time was 124 (61-256) minutes. Median cross-clamp time was 60 (19-152) minutes. There were six early deaths (5.1%). The overall median time of the cardiac intensive care unit stay was 4 (1-17) days, with a median ventilator support of 7.3 (1.0-181.0) hours. The mean room air saturation was 90.00%±4.68% before discharge. Median length of chest tube drainage was 10 (4-45) days. Multiple logistic analysis confirmed that heterotaxy syndrome was the only independent predictor for postoperative renal insufficiency. Operations with aortic cross-clamping (OR=26.184, 95% CI 1.712-400.451), preoperative sinus mode dysfunction (OR=6.777, 95% CI 1.495-30.721) and cross-clamp time over 60 minutes (OR=1.036, 95% CI 1.002-1.076) were predictors for prolonged chest tube drainage. A total of 110 patients were followed up for 17 (8-47) months with 2 deaths and 1 with thrombosis. No reoperation occurred. ConclusionThe one-stage Fontan procedure can be performed with satisfactory outcomes. Staged strategies for operations may be appropriately loosen for selected elder children.
