We aimed to explore the application of three-dimensional (3D) printing technology with problem-based learning (PBL) teaching model in clinical nursing education of congenital heart surgery, and to further improve the teaching quality of clinical nursing in congenital heart surgery. In this study, a total of 132 trainees of clinical nursing in congenital heart surgery from a grade-A tertiary hospital in 2019 were selected and randomly divided into 3D printing group or traditional group. The 3D printing group was taught with 3D printed heart models combined with PBL teaching technique, while the traditional group used conventional teaching aids combined with PBL technique for teaching. After the teaching process, the 2 groups of nursing students were assessed and surveyed separately to evaluate the results. Compared to the traditional group, the theoretical scores, clinical nursing thinking ability, self-evaluation for comprehensive ability, and teaching satisfaction from the questionnaires filled by the 3D printing group were all higher than the traditional group. The difference was found to be statistically significant ( P < .05). Our study has shown the 3D printing technology combined with the PBL teaching technique in the clinical nursing teaching of congenital heart surgery achieved good results.
Background We present here our experience with surgical management of traumatic diaphragmatic hernia, trying to find out the era impact of different periods on the outcome and risk factors of mortality. Methods A series of 63 patients with traumatic diaphragmatic hernia were referred to us and operated on during March, 1990-August, 2017. The patient records were reviewed and statistically analyzed to demonstrate injury characteristics and to find out optimal treatment strategy, risk factors of death as well as the difference between two periods (1990–2005, 2005–2017) divided by introduction of computed tomography at our institution. Results The overall mean age was 31.2 ± 16.3 years old with a female to male ratio of 11/52. The mechanism was penetrating trauma in 19 cases (30.2%), and blunt trauma in 44 cases (69.9%). Two thirds of the patients in the second group (2005–2017) yet none in the first group (1990–2005) underwent computed tomography. Ten patients (15.9%), of which 8 in the first and the other 2 in the second group (p = .042), had late diagnoses. The most commonly used incision was a thoracotomy (n = 43, 89.6%). There was no statistical difference in etiology or mortality between the two periods. Univariate analysis showed survivors were younger, and had lesser injury severity scores (ISS) and lower American Association for the Surgery of Trauma (AAST) grade than non-survivors. By multivariate logistic regression analysis, increased age (odds ratio, 1.275; p = .013) and greater ISS (OR, 1.174; p = .028) were risk factors of death in all patients. Conclusions High-definition computed tomography has significantly improved the preoperative diagnosis rate. The transthoracic approach could be used in selected cases with traumatic diaphragmatic hernia with good outcomes. Patients with greater ISS and advanced ages are at a higher risk of death.
Background The focus of clinical care after treating congenital heart disease (CHD) has shifted from saving patients’ lives to improving their quality of life. This study aimed to examine the influence of minimally invasive and traditional surgeries on the quality of life of children with CHD. Methods This was a retrospective cross-sectional study. A total of 459 children aged 2–18 years with CHD treated at Second Xiangya Hospital of Central South University from July 2016 to June 2017 were enrolled, among whom 219 underwent minimally invasive surgery and 240 traditional surgery. The quality of life of children with CHD after surgery was reported by the patients’ parents. We applied propensity score matching to correct for confounding factors and conducted multiple linear regression analysis to examine the related effects of minimally invasive and traditional surgeries on the quality of life of children with CHD. Results The scores of problems related to perceived physical appearance in children undergoing minimally invasive surgery was higher than those in those undergoing traditional surgery (p = 0.004). Different treatment modes were independent influencing factors for problems related to perceived physical appearance in children with CHD. There was no significant difference in average treatment effect scores of children undergoing different surgical procedures in other quality of life dimensions (problems related to cardiac symptoms and their treatment, drug treatment, anxiety regarding treatment, cognitive psychology, and communication), suggesting that different operation modes were not independent influencing factors for these related problems. Conclusion Compared with traditional surgery, minimally invasive surgery can significantly improve the physical appearance perception scores of children with CHD after surgery. Therefore, minimally invasive surgery can improve the quality of life of children with CHD.
