ABSTRACT
Objective:To summarized the experience of 149 cases of critical pediatric cardiac surgery in a single-center during the epidemic period, for providing a safe and feasible management strategy.Methods:Based on the epidemiological characteristics of COVID-19, a strategy consisting of 14 days of isolation was established for the arrangement of cardiac surgery in children during the epidemic period. Retrospective analysis of clinical data of 149 cases of critical cardiac surgery performed from January 23, 2020 to March 20, 2020 under the guidance of this strategy. The primary composite endpoint was death and suspected or confirmed COVID-19.Results:The median age of the children undergoing surgery was 136 days; 73(49.0%) cases were male. Twenty-one cases (14.1%) came from Shanghai, one case (0.7%) came from Hubei Province, and 127 cases (85.2%) came from areas other than Hubei and Shanghai. One patient (0.7%) outside Shanghai who had been isolated for less than 14 days carried emergency surgery under special protection; other 148 patients (99.3%) underwent elective early repair procedure. One patient (0.7%) died, and no COVID-19 was confirmed or suspected.Conclusion:During the COVID-19 epidemic, pediatric cardiac surgery can be safely performed using a specific management strategy, which can be used as a reference when major public health events occur.
ABSTRACT
@#Objective To compare the outcomes of sutureless technique and conventional technique in the surgical repair for infracardiac total anomalous pulmonary venous connection (TAPVC). Methods The clinical data of 46 consecutive patients with infracardiac TAPVC undergoing surgical repair in our hospital between June 2014 and April 2019 were retrospectively analyzed. Patients with combined congenital cardiac anomalies such as single ventricle and tetralogy of Fallot were excluded. Patients were divided into a conventional technique group and a sutureless technique group according to the surgical techniques. There were 35 patients in the conventional technique group, including 28 males (80.0%) and 7 females (20.0%) with a median age of 21 (8, 42) d and a median weight of 3.6 (3.0, 4.0) kg. There were 11 patients in the sutureless technique group, including 8 males (72.7%) and 3 females (27.3%) with a median age of 14 (6, 22) d and a median weight of 3.5 (2.9, 3.6) kg. The curative effect of the two groups was compared. Results There were 5 deaths (10.9%) in the conventional technique group, including 4 in-hospital deaths (8.7%) and 1 late death (2.2%). Overall mortality of the conventional technique group (14.3%, 5/35) was higher than that of the sutureless technique group (0.0%, 0/11), although the difference was not statistically significant (P=0.317). Cox regression analysis showed that sex (P=0.042), age at repair (P=0.028), cardiopulmonary bypass time (P=0.007), aortic cross-clamping time (P=0.018) and duration of ventilation (P=0.042) were risk factors for postoperative mortality. The median follow-up was 18.00 (5.00, 37.75) months. Postoperative pulmonary venous obstruction occurred in 22 patients of the conventional technique group, which was significantly more than that of the sutureless technique group (P=0.000). Conclusion For infracardiac TAPVC, sutureless technique can reduce the incidence of postoperative pulmonary venous obstruction compared with conventional technique.
ABSTRACT
Objective To observe the effect of magnetic attachments application on oral denture restoration .Methods A to-tal of 50 patients with overdenture restoration treatment in this department from April 2012 to April 2014 were enrolled .Abutment tooth were given magnetic attachments restoration after preparations .The masticatory efficiency ,patient satisfaction and post-resto-ration complication were observed and recorded .Results The immediate masticatory efficiency after magnetic attachments restora-tion (0 .65 ± 0 .09) was significant higher than that before restoration(0 .22 ± 0 .04) ,t= 20 .812 ,P 0 .05) .There were 49 cases of immediate satisfaction and 1 case of satisfactory after restoration ,the patient satisfaction rate was 100% ,it was significant higher than that of before restoration(46% ) ,χ2 = 31 .815 ,P< 0 .05 .There were 45 ca-ses of satisfaction and 5 case of satisfactory after restoration ,the patient satisfaction rate was 100% ,it was significant higher than that of before restoration (χ2 = 31 .815 ,P< 0 .05) .Conclusion The masticatory efficiency could be improved significantly by mag-netic attachments to restore denture depletion or dentition defect ,compare with traditional denture ,it can significant shorten adapt time for patients ,and it can enhance patient satisfaction .It has wide prospect for future clinical application .
