RESUMO
@#Objective To study the safety of right vertical infra-axillary thoracotomy (RVIAT) in the repair of ventricular septal defect (VSD) and the optimal age for RVIAT. Methods Between June 2014 and June 2018, 441 children underwent VSD repair via RVIAT in our hospital. According to the age, they were divided into four groups: a 4 months to 1 year old group (R1 group, n=123), a 1-2 years old group (R2 group, n=106), a 2-5 years old group (R3 group, n=166), a >5 years old group (R4 group, n=46). The clinical effects of the patients were compared. Results All the operations were successfully performed and no serious complication was found in all groups. No statistical difference was observed in the operation time, blood loss during operation, thoracic drainage 24 h after operation among groups (P>0.05). The cardiopulmonary bypass time, aortic cross-blocking time and ICU stay time in the R1 and R2 groups were longer than those in the R3 and R4 groups (P<0.05). In the R1 group, the postoperative ventilating time and postoperative hospital stay time were longer, and the blood transfusion volume was more than those in the R3 and R4 groups (P<0.05). The incidence of postoperative complications was higher in the R4 group than that in the R1 and R3 groups (P<0.05). Conclusion VSD repair via RVIAT may be more effective in children >2 years old, and 2-5 years old may be the optimal age.
RESUMO
Three dimensional (3D)printing technology has been adapted to medical applications at an impressive rate since 2011.It has been widely used in the field of craniofacial,oromaxillofacial,orthopedic and cardiothoracic specialties.3D biometric printing represents one of the highest levels of 3D printing technology and it can be used to print individual anatomical models,implants,prosthetics,external fixators,splints,surgical instrumentation,and for surgical guidance.The application of 3D printing technology in pediatric cardiothoracic surgery start late and has difficulties.This technology is mainly used for cardiothoracic surgery guidance and preoperative schemes selection,organ and tissue transplantation at present.It is of high value in the diagnosis and treatment of complex congenital heart disease,complex trachea and esophagus malformation and thoracic tumor.This article reviews the application progress and prospect of 3D printing technology in the field of pediatric cardiothoracic surgery.
RESUMO
Objective To explore the psychological experience of ICU nurses who had worked follow different work patterns, and find the most appropriate staffing model. Methods A phenomenological approach of qualitative research was conducted in 5 ICU nurses by intensive interview,then the data collected were read, analyzed, reflected,finally the theme was got. Results In the work pattern of shifted every 12 hours, with low work frequency and strong feeling of fatigue. In the work pattern of shifted every 8 hours, with high work frequency and the disadvantage of nurse- patient relationship. In the short-time continuous APN work pattern, with continuous management of patients' condition, promotion of nurse-patient relationship, improvement of doctor-nurse relationship, comparatively stable biological clock. Conclusions The short-time continuous APN work pattern can concentrate nurses' work and rest time, relieve the press that caused by the shifted work, at the same time, promote the patients',patients' family and doctors' satisfaction degree with nursing work, increase nurses' effect in the ICU team, guarantee the quality of care, eventually ensure the patients' safety.
