Objective To investigate the off-label prescriptions in pediatrics in West China Second University Hospital and to analyze the reasons and performance, so as to provide the baseline data for improving the rationality drug use in pediatrics in China. Methods The prescriptions of pediatrics outpatient department were randomly selected from May 2008 to April 2009; and the off-label use was analyzed according to the package inserts in the following aspects, the types of off-label use, the rate of off-label use in different age groups and categories of medicine. Results Of the total 2 400 prescriptions, 1 398 (58.25%) involving off-label use. All sample prescriptions contained 6028 records, 1 923 (31.90%) involving off-label use. The problems such as dosage (45.98%), frequency (21.17%) and age (18.19%) were the top-three types of off-label use. The rate in different age groups ranked as the top-three were school-age (61.56%), followed by preschool (60.77%) and infants (57.56). The top-five categories of medicines in off-label use were anti-allergy drugs (49.45%), digestive system drugs (49.32%), externally applied drugs (41.49%), Chinese patent drugs (34.60%) and nervous system drugs (33.78%). Conclusion The off-label drug use is widespread in pediatrics outpatient department. It is an effective approach to reduce off-label use and improve drug safety through strictly abiding by the instruction of usage and dosage as well as selecting a suitable dosage form.
Objective
To explore the application of the Handbook for the Training Nurses in the standardized training for nurses in pediatric surgery.
Methods
Twenty-four training nurses trained under the instruction of the Handbook for the Training Nurses in Department of Pediatric Surgery from July 2014 to December 2015 were included as the observation group. Their training effects were compared historically with those of twenty-four training nurses who were trained without the help of the handbook from January 2013 to June 2014 (the control group).
Results
After the completion of the half-year training, theoretical score of training nurses in the observation group was better than that in the control group, and the difference was significant (87.16±4.18 vs. 83.71±5.46; t=2.492, P=0.016). Meanwhile, the specialist practical skill examination of training nurses in the observation group, such as femoral vein blood collection, replacement of drainage bag and indwelling needle infusion in children, and emergency practical skill examination such as cardiopulmonary resuscitation and the use of simple respirator were higher than those in the control group; and the working performance scores of training nurses in the observation group, such as the ability to adapt to the environment, patient satisfaction, nursing document writing, work efficiency and morning questions were better than those in the control group; the differences were significant (P< 0.05).
Conclusion
The Handbook for the Training Nurses can help the training nurses to adjust their working environment, master the practical skills and nursing knowledge in pediatric surgery.
Objective To explore the use of ChatGPT (Chat Generative Pre-trained Transformer) in pediatric diagnosis, treatment and doctor-patient communication, evaluate the professionalism and accuracy of the medical advice provided, and assess its ability to provide psychological support. Methods The knowledge databases of ChatGPT 3.5 and 4.0 versions as of April 2023 were selected. A total of 30 diagnosis and treatment questions and 10 doctor-patient communication questions regarding the pediatric urinary system were submitted to ChatGPT versions 3.5 and 4.0, and the answers to ChatGPT were evaluated. Results The answers to the 40 questions answered by ChatGPT versions 3.5 and 4.0 all reached the qualified level. The answers to 30 diagnostic and treatment questions in ChatGPT 4.0 version were superior to those in ChatGPT 3.5 version (P=0.024). There was no statistically significant difference in the answers to the 10 doctor-patient communication questions answered by ChatGPT 3.5 and 4.0 versions (P=0.727). For prevention, single symptom, and disease diagnosis and treatment questions, ChatGPT’s answer scores were relatively high. For questions related to the diagnosis and treatment of complex medical conditions, ChatGPT’s answer scores were relatively low. Conclusion ChatGPT has certain value in assisting pediatric diagnosis, treatment and doctor-patient communication, but the medical advice provided by ChatGPT cannot completely replace the professional judgment and personal care of doctors.
ObjectiveTo review the characteristics of registered industry-sponsored clinical trials of pediatric drugs and vaccines in China and to provide references for promoting the development of new pediatric drugs. MethodsWe searched ClinicalTrials.gov and the Chinese Clinical Trial Registry for completed registered industry-sponsored clinical trials of pediatric drugs and vaccines from the database inception to September 11, 2022. Data including the date the trial was first posted, product type (drug or vaccine), sample size, and other information to describe the general characteristics of pediatric clinical trials were collected. The studies were divided into 2 phases based on the trial posted date, 2005―2010 and 2011―2022, reflecting the enactment of pediatric drug clinical trial policies in recent years. The quality of trial registration and the main characteristics of interventional trials in the 2 phases were then compared. Exploring the results attached to industry and non-industry sponsored clinical trials. ResultsData for 145 trials were collected, and the largest proportion (63.4%) involved vaccines. Randomized control trial (RCT) was the study type with the highest percentage (68.3%). The average report completion rate for registered interventional trials was 81.0%. Compared with 2005―2010, the percentage of average report completions, pediatric drug clinical studies, multicenter, RCTs, and double-blinded registered trials increased in 2011―2022. The proportion of positive outcomes in pediatric clinical trials sponsored by industries was higher than those sponsored by non-industry. ConclusionThe majority of completed pediatric clinical trials sponsored by industries are for vaccines, in line with the promotion of pediatric policies. The quality of trial registration has improved, but not significantly, and some characteristics of trial design have changed. The proportion of positive outcomes in pediatric clinical trials sponsored by industries is higher. And further promotion of pediatric clinical trials is needed.
Objective To assess the influence of dexmedetomidine on the recovery of pediatric patients after sevoflurane anesthesia. Methods Such databases as PubMed (1966 to March 2012), The Cochrane Library (Issue 1, 2012), EBSCO (ASP) (1984 to March 2012), Journals@Ovid Full Text (1993 to March 2012), CBM (1978 to March 2012), CNKI (1979 to March 2012), VIP (1989 to March 2012), and WanFang Data (1998 to March 2012) were searched to collect randomized controlled trials (RCTs) about the influence of dexmedetomidine on the recovery of pediatric patients after sevoflurane anesthesia, and the references of the included studies were also retrieved. Two researchers extracted the data and evaluated the methodological quality of the included studies independently. Then the RevMan 5.2 software was used for meta-analysis. Results A total of 16 RCTs involving 1 217 patients were included. The results of meta-analysis showed that, compared with the placebo, dexmedetomidine could reduce the occurrence of emergence agitation (OR=0.18, 95%CI 0.13 to 0.25, Plt;0.000 01) and increase the occurrence of postoperative lethargy (OR=0.14, 95%CI 0.03 to 0.68, P=0.01), but there were no differences in the occurrence of side effects including bronchospasm, bucking, breathholding, and oxygen desaturation. Dexmedetomidine could also reduce mean arterial blood pressure (MAP) and heart rate (HR) of pediatric patients during the recovery period after sevoflurane anesthesia, but it increased emergence time (MD=2.14, 95%CI 0.95 to 3.33, P=0.000 4), extubation time (MD=1.26, 95%CI 0.51 to 2.00, P=0.000 9) and the time of staying in PACU (MD=4.72, 95%CI 2.07 to 7.38, P=0.000 5). Conclusions For pediatric patients recovering from sevoflurane-based general anesthesia, dexmedetomidine can reduce the occurrence of emergence agitation, and is helpful to maintain the hemodynamic balance. But it prolongs emergence time, extubation time (or the time of using the laryngeal mask) and the time of staying in PACU, and increases the occurrence of postoperative lethargy.
Objective To systematically review the risk factors of tic disorder (TD) in children. Methods Databases including PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, CBM, VIP, and WanFang Data were electronically searched to collect observational studies on children with TD from inception to June 29th 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.3 software. Results A total of 32 studies involving 556 560 children were included. The results of meta-analysis showed that the risk factors for TD were as follows: male (OR=2.23, 95%CI 1.08 to 4.61, P=0.03), premature delivery (OR=1.66, 95%CI 1.04 to 2.64, P=0.03), low birth weight (OR=1.27, 95%CI 1.07 to 1.50, P=0.005), history of neonatal jaundice (OR=7.46, 95%CI 1.15 to 48.42, P=0.04), other adverse factors in the perinatal period (OR=2.74, 95%CI 1.89 to 3.98, P<0.000 01), poor eating habits (OR=2.11, 95%CI 1.52 to 2.93, P<0.000 01), long-term viewing of electronic products (OR=2.22, 95%CI 1.31 to 3.75, P=0.003), history of febrile convulsions (OR=2.43, 95%CI 1.21 to 4.86, P=0.01), recurrent respiratory infection (OR=2.63, 95%CI 1.49 to 4.64, P=0.000 8), chronic tonsillitis (OR=2.01, 95%CI 1.31 to 3.09, P=0.001), rhinopathy (OR=1.77, 95%CI 1.35 to 2.31, P<0.000 1), attention deficit hyperactivity disorder (ADHD) (OR=5.32, 95%CI 3.77 to 7.51, P<0.000 01), decreased blood iron content (OR=3.68, 95%CI 1.56 to 8.67, P=0.003), family history of TD (OR=6.33, 95%CI 3.20 to 12.53, P<0.000 01), family history of mental illness (OR=2.39, 95%CI 2.03 to 2.83, P<0.000 01), maternal mental disorder during pregnancy (OR=2.49, 95%CI 1.99 to 3.11, P<0.000 01), alcohol drinking during pregnancy (OR=1.40, 95%CI 1.09 to1.79, P=0.007), smoking or passive smoking during pregnancy (OR=1.84, 95%CI 1.68 to 2.01, P<0.000 01), and corporal punishment (OR=3.57, 95%CI 1.52 to 8.34, P=0.003). Parity (second birth and above) (OR=0.41, 95%CI 0.25 to 0.68, P=0.000 6) was a protective factor for tic disorder. Conclusions Current evidence shows that the incidence of TD is related to gender, family history of mental illness, maternal life habits during pregnancy, perinatal history, chronic respiratory diseases, abnormal trace elements, and strict education methods, etc. Moreover, parity is a protective factor for the occurrence of TD. Due to the limited quantity and quality of included studies, more high-quality studies are required to verify the above conclusions.
ObjectiveTo analyze the risk factors for pediatric heart transplantation at a single center and its impact on short-term prognosis, providing experience and reference for pediatric heart transplantation. MethodsThe children who underwent heart transplantation from May 2022 to May 2024 at the Seventh Medical Center of Chinese PLA General Hospital were included in this study. We conducted a retrospective analysis of the clinical data of donors and recipients, perioperative conditions, and postoperative complications. The double-lumen venoplasty technique was used for all surgeries. Basiliximab was applied for immune induction during and after the operation (on the 4th day). Tacrolimus+mycophenolate mofetil+prednisolone acetate was used for postoperative immunosuppressive maintenance treatment. According to whether patients had a history of extracorporeal membrane oxygenation (ECMO) installation before surgery, they were divided into an ECMO group and a non-ECMO group. The postoperative ICU stay time, postoperative ventilator assistance time, aortic clamping time, cardiopulmonary bypass time, recipient body surface area, left ventricular ejection fraction, X-ray cardiothoracic ratio, donor heart cold ischemia time, and the weight ratio between donor and recipient were compared between the two groups, and correlation analysis was performed. ResultsA total of 17 children were included, with 10 (58.8%) males and 7 (41.2%) females. Their ages ranged from 7 months to 16 years, with a median age of 11.0 (10.0, 13.0) years. Their weights ranged from 7.0 to 67.5 kg, with an average weight of (41.6±16.7) kg. Of the 17 children, 16 survived post-operation, and 1 died 5 days after the operation. Five patients were ABO incompatible heart transplantations, and 11 patients had a history of ECMO installation before surgery. The left ventricular ejection fraction of the non-ECMO group was higher than that of the ECMO group (t=2.188, P=0.045). The postoperative ICU stay time and postoperative ventilator assistance time (r=0.599, P=0.011), and cardiopulmonary bypass time (r=0.667, P=0.003) were positively correlated. The cardiothoracic ratio was negatively correlated with the postoperative ventilator assistance time (r=?0.527, P=0.030). ConclusionPediatric heart transplantation is an effective treatment method for children with end-stage heart failure. The left ventricular ejection fraction of the recipient may be a predictive factor indicating that the child needs ECMO assistance. Longer extracorporeal circulation time and larger recipient body surface area may affect the surgical process and perioperative prognosis.
ObjectiveTo analyze the short- and long-term therapeutic effects of heart transplantation in children. MethodsA retrospective study was conducted on recipients and donors who underwent heart transplantation at the 7th People’s Hospital of Zhengzhou from May 2018 to August 2023, analyzing their clinical characteristics, surgical data, postoperative complications, and survival rates. ResultsA total of 22 children underwent heart transplantation, including 14 males and 8 females, with a median age of 13.5 (10.0, 15.0) years and a median weight of 41.9 (30.5, 55.4) kg. The primary diseases included: dilated cardiomyopathy in 16 patients, hypertrophic cardiomyopathy in 1 patient, myocardial dysplasia in 3 patients, right ventricular dysplasia in 1 patient, and congenital heart disease with abnormal coronary artery origin in 1 patient. The median age of the donors was 21.0 (13.0, 29.0) years, and the median weight was 50.5 (47.3, 75.0) kg. The blood types of the donors and recipients were the same, with type A in 10 patients, type B in 5 patients, type O in 5 patients, and type AB in 2 patients. Before transplantation, all children had a New York Heart Association cardiac function grade Ⅳ, with 1 patient assisted by intra-aortic balloon pump (IABP), 3 patients assisted by extracorporeal membrane oxygenation (ECMO), 2 patients assisted by continuous renal replacement therapy (CRRT), and 2 patients on mechanical ventilation. Nine patients met the criteria for emergency child status allocation, and the panel reactive antibody level in the patients was<10%. The median cold ischemic time of the donor heart was 355.0 (262.0, 395.5) min, the median aortic cross-clamping time was 45.0 (38.3, 51.3) min, the median mechanical ventilation time was 22.5 (16.8, 52.5) h, the median postoperative hospital stay was 29.5 (20.0, 43.0) d, and the median intensive care unit stay was 6.0 (5.0, 8.3) d. After surgery, 4 patients were assisted by ECMO, 2 patients by CRRT, and 7 patients developed complications, including lung fungal infection in 6 patients, liver and kidney dysfunction in 1 patient, local wound non-union and mediastinal infection in 1 patient, and multiple organ failure in 1 patient. Kaplan-Meier curve analysis showed that the survival rates of children after surgery were 91.3% at 1 year and 3 years; the survival rates of adult heart transplant recipients at our center were 86.7% and 73.8% at 1 year and 3 years, respectively, indicating that the survival rate of children with heart transplantation was higher than that of adult patients. ConclusionHeart transplantation is an effective treatment for end-stage heart failure in children, and the short- and long-term survival rates of children with heart transplantation are superior to those of adults. There are still many difficulties to be solved in pediatric heart transplantation, requiring joint efforts from society and the medical community.
Abstract： Objective To analyze the manifestation, treatment，outcome and potentially predisposing risk factors of perioperative thromboembolism after cavo-pulmonary connection, and to assess the effects of our prophylactic antithrombotic strategy.?Methods?Clinical data of 264 cases of bidirectional Glenn and 224 cases of total cavopulmonary connection （TCPC） operations undertaken from September 2005 to December 2010 in Fu wai hospital were retrospectively analyzed. Perioperative thromboembolic complications occurred in 9 patients. 5 of them were after bidirectional Glenn, 4 were after TCPC. Most of the 9 patients had at least one thrombi-related risk factor. The routine prophylactic antithrombotic therapy after these operations were intravenous infusion of heparin 10 U/（kg·h） initially, followed with oral aspirin 1-3 mg/（kg·d）. Results Thromboembolic events occurred within 7 days after the operation in 6 cases, appeared 2 to 4 weeks after the surgery in 3 cases. All 9 patients received anticoagulation with heparin. One patient also undertook take-down operation. 3 （33%） patients died, accounting for 33% （1/3）, and 18% （2/11） of the early deaths after bidirectional Glenn and TCPC operations. Clinical symptoms improved or disappeared in the remaining 6 patients. Conclusion The mortality of perioperative thromboembolic complications after cavo-pulmonary connection is high, consisting of the important cause of early deaths after these procedures. Our prophylactic anticoagulation strategy proved to be effective, though some thrombi-relatedrisk factors still need to be avoided.
ObjectiveTo evaluate the health economics indexes of day surgery mode and traditional specialist hospitalization mode, and to provide reference for the selection of different hospitalization mode of inguinal-type cryptorchidism in children.MethodsThe patients with unilateral cryptorchidism under 5 years old between January 2017 and January 2018 in Chongqing Children’s Hospital were selected in this study. According to different inpatient surgery modes, the included children were divided into day surgery group (day group) and special in-hospital surgery group (specialty group). The general data of patients, treatment indicators, incidence of complications, postoperative testicular atrophy rate, recurrence, nosocomial infection, hospitalization time, hospitalization cost, satisfaction of patients, and other health effect indicators between the two operation modes were compared. The treatment effect indexes and cost-effect ratio of the two modes were statistically analyzed.ResultsA total of 198 children were included, including 83 in the day group and 115 in the specialty group. The patients in both groups underwent orchiopexy by small inguinal dermatoglyph and scrotal incision. There was no statistically significant difference in the affected side, source area, postoperative complications, or nosocomial infection between the two groups (P>0.05). The patients in the specialty group were older than those in the day group [(27.60±11.04) vs. (20.88±9.48) months old; t=4.586, P<0.001]; the bed occupancy time [(118.60±10.80) vs. (23.95±5.90) h; t=72.353, P<0.001] and operation time [(0.45±0.15) vs. (0.38±0.12) h; t=2.946, P=0.004] in the specialty group were longer than those in the day group. The difference was statistically significant in hospitalization expenses between the two groups (χ2=155.374, P<0.001); 92.8% of the children in the day group spent less than 5 000 yuan, while 95.7% of the children in the specialty group spent more than 5 000 yuan. The American Society of Anesthesiologists scores in the specialty group were higher than those in the day group (χ2=44.870, P<0.001). The treatment effect indexes in the day group and the specialty group were 0.99 and 1.01, respectively, and the cost-effect ratios were 3 850 and 6 657, respectively. The economic benefit of the day group was better.ConclusionsThe cost-effectiveness of day surgery is better than that of specialized inpatient surgery. Therefore, this model can be recommended for children who meet the indications of day surgery.
