ObjectiveTo explore the risk factors and countermeasures of the perfusionist-related near-miss event (NME) in cardiopulmonary bypass (CPB). MethodsThe clinical data of the patients who underwent cardiac surgery in the Department of Cardiovascular Surgery, Nanfang Hospital, Southern Medical University from March 2020 to July 2021 were retrospectively analyzed. According to whether NME occurred during the operation, the patients were divided into an NME group and a non-NME group. The clinical data of the two groups were compared, and the risk factors for NME were analyzed. ResultsA total of 702 patients were enrolled, including 424 males and 278 females with a median age of 56.0 years. There were 125 patients in the NME group and 577 patients in the non-NME group. The occurrence rate of NME was 17.81%. Univariate analysis showed that there were statistical differences between the two groups in the gender, body surface area, CPB time, European system for cardiac operative risk evaluation score, emergency surgery, type of surgery, night CPB initiation, modified ultrafiltration use, multi-device control, average operation time, et al. (all P<0.05). The above variables were dimensionality reduction processed by least absolute shrinkage and selection operator regression, and the λ of minimum mean square error of 10-fold cross validation was 0.014. The variables of the corresponding model were selected as follows: multi-device control, night CPB initiation, minimum hematocrit, modified ultrafiltration use, CPB time. The results of multivariate logistic regression showed that night CPB initiation [OR=9.658, 95%CI (4.735. 19.701), P<0.01] and CPB time [OR=1.003, 95%CI (1.001, 1.006), P=0.014] were independent risk factors for NME. ConclusionNight CPB initiation and CPB time are independent risk factors for NME during CPB, which should be recognized and early warned in clinical work.
Objective To construct a risk prediction score model for serious adverse event (SAE) after cardiac catheterization in patients with adult congenital heart disease (ACHD) and pulmonary hypertension (PH) and verify its predictive effect. Methods The patients with PH who underwent cardiac catheterization in Wuhan Asian Heart Hospital Affiliated to Wuhan University of Science and Technology from January 2018 to January 2022 were retrospectively collected. The patients were randomly divided into a model group and a validation group according to the order of admission. The model group was divided into a SAE group and a non-SAE group according to whether SAE occurred after the catheterization. The data of the two groups were compared, and the risk prediction score model was established according to the results of multivariate logistic regression analysis. The discrimination and calibration of the model were evaluated using the area under the receiver operating characteristic (ROC) curve and the Hosmer-Lemeshow test, respectively. Results A total of 758 patients were enrolled, including 240 (31.7%) males and 518 (68.3%) females, with a mean age of 43.1 (18.0-81.0) years. There were 530 patients in the model group (47 patients in the SAE group and 483 patients in the non-SAE group) and 228 patients in the validation group. Univariate analysis showed statistical differences in age, smoking history, valvular disease history, heart failure history, N-terminal pro-B-type natriuretic peptide, and other factors between the SAE and non-SAE groups (P<0.05). Multivariate analysis showed that age≥50 years, history of heart failure, moderate to severe congenital heart disease, moderate to severe PH, cardiac catheterization and treatment, surgical general anesthesia, and N-terminal pro-B-type natriuretic peptide≥126.65 pg/mL were risk factors for SAE after cardiac catheterization for ACHD-PH patients (P<0.05). The risk prediction score model had a total score of 0-139 points and patients who had a score>50 points were high-risk patients. Model validation results showed an area under the ROC curve of 0.937 (95%CI 0.897-0.976). Hosmer-Lemeshow goodness-of-fit test: χ2=3.847, P=0.797. Conclusion Age≥50 years, history of heart failure, moderate to severe congenital heart disease, moderate to severe PH, cardiac catheterization and treatment, general anesthesia for surgery, and N-terminal pro-B-type natriuretic peptide≥126.65 pg/mL were risk factors for SAE after cardiac catheterization for ACHD-PH patients. The risk prediction model based on these factors has a high predictive value and can be applied to the risk assessment of SAE after interventional therapy in ACHD-PH patients to help clinicians perform early intervention.
Endoscopic retrograde cholangiopancreatography (ERCP) is currently the first-line minimally invasive diagnosis and treatment of biliary and pancreatic diseases. With the increasing popularity of ERCP, ERCP-related adverse events which include post-ERCP pancreatitis, cholecystitis, cholangitis, bleeding, perforation, etc., have received more and more attention. In response to the controversy and problems in the management of these adverse events, the European Society of Gastrointestinal Endoscopy published the guidelines for ERCP-related adverse events in December 2019. The paper interprets the key points in the guideline to provide references for clinical practice.
ObjectiveTo explore the psychological process and needs of the second victims of medical adverse events after the occurrence of adverse events, so as to provide reference for the psychological intervention strategies of medical institutions for the second victims of medical adverse events.MethodsThe second victims of medical adverse events in the First People’s Hospital of Ziyang were selected from April to July 2019. Qualitative research method was used to conduct semi-structured in-depth interviews with the second victims. Colaizzi method was used to analyze the transcripts through reading and rereading, coding, and thematizing. ResultsA total of 22 second victims of medical adverse events were interviewed. The second victims of medical adverse events experienced negative emotional experience, and the desire to seek emotional support was urgent. The psychological process of the second victims of medical adverse events mainly involved five stages: fear, anxiety, depression, guilt and recovery. Emotional support hada positive effect on regression. Conversely, negative or lack of emotional support had a negative effect on regression. ConclusionsThe emotional experience of the second victims of medical adverse events is relatively staged, and the recovery and regression are greatly affected by internal and external factors. Hospital administrators should take active measures and establish an emotional support mechanism for adverse events in order to reduce psychosomatic injuries and improve medical quality and efficiency.

Objective To explore the emergence agitation resulting from postoperative indwelling urethral catheters in patients of thoracic surgery. Methods In this prospective cohort study, we recruited 140 patients who were scheduled for thoracic surgery under general anesthesia in West China Hospital from January through April 2014. These patients were divided into two groups including a control group and a trial group with 70 patients in each group. The patients in the control group had indwelled urethral catheter routinely. The catheter removed after the surgery at operation room in the trial group. Intraoperative urinary volume, emergence agitation (EA) occurrence, postoperative urinary retention, and urethral irritation were recorded. Results There was no statistical difference in postoperative urinary retention rate between the control group and the trial group (1.43% vs. 2.86%, P=0.230). However, the urethral irritation rate in the control group was significantly higher than that in the trial group (12.86% vs. 0.00%, P=0.012) . And there was a statistical difference in adverse event rate (2.86% vs. 0.00%, P=0.039) between the two groups. There was a significantly higher incidence of urethral irritation in male patients (20.51%, 8/39) than female patients (3.23%, 1/31, P=0.033).The rate of EA in the control group was significantly higher than that in the trial group (28.57% vs. 12.86%, P=0.010). There was a significantly higher EA rate in the patients who had urethral irritation by postoperative indwelling catheters compared with those without indwelling catheters (45.00% vs. 12.86%, P=0.043). Conclusion This study suggests that postoperative EA is a result from urethral irritation than local pain, and the EA rate can be decreased by removal of catheter before anaesthetic recovery.
Objective To explore the relationship between macro-economic indicators and incidences of adverse events linked to intrauterine devices (IUDs). Methods Data on IUD-associated adverse events were collected from a cohort study conducted between September 2005 and December 2006. Regional economic data were from the 2006 National Economic and Social Development Statistical Bulletins and Statistical Yearbooks of various regions. A total of 20,220 IUD users in 236 towns in Jiangsu, Shanghai, Guangdong, Anhui, Sichuan, and Chongqing provinces in China were included in this study. Linear correlation and regression analyses were used to analyze the relationships between regional income and total incidences of adverse events, incidences of mild adverse events, and incidences of severe adverse events. Results Incidences of total adverse events and mild adverse events were positively correlated with regional economic level (rs=0.336, Plt;0.05; rs=0.272, Plt;0.05), while incidences of severe adverse events were not correlated with regional economic level. Conclusions The positive relationship between regional economic level and reported IUD-associated mild adverse events likely reflects income-related disparities in women seeking care and receiving treatment for mild adverse events. This points to a need to improve both public health education and the quality of health services, particularly in poorer areas.
Objective To investigate the early and long-outcomes of coronary artery bypass grafting(CABG) in acute myocardial infarction (AMI) patients with coronary artery disease(CAD)(age≤45 years). Methods Data of 596 adult CAD patients (include AMI and Angina) who underwent CABG in our hospital were collected retrospectively from May 2010 to October 2018. In an AMI group, 234 were male patients with an average age of 41.59±3.79 years; 26 were female patients with an average age of 41.64±3.03 years. In an angina group, 280 were male patients with an average age of 42.19±2.90 years; 56 were female patients with an average age of 41.54±3.52 years. Preoperative baseline variables, perioperative mortality, major adverse cardiac and cerebrovascular events (MACCE) were compared between two group. Results There was no significant difference in all preoperative variables. Seven patients were died and the hospital mortality rate was 1.23% (1.54% vs. 0.89%, P=0.477). The complications including reoperation for bleeding, cerebral infarction, renal failure and atrial fibrillation arrhythmia were without significant difference between two group (P>0.05). The intensive care unit stay duration (30.66±27.46 h vs. 23.96±15.11 h), intubation duration (22.54±22.31 h vs. 18.64±11.81 h) and hospitalization costs (97 186±33 741¥ vs. 90 081±24 537¥, P=0.003) were greater in the AMI group. The hospital mortality rate and complications rate were without significant difference between STEMI (ST segment elevated myocardial infarction) and NSTEMI (non-ST-segment elevated myocardial infarction) subgroups (P>0.05). The follow-up rate was 92.6% (546 patients) and the follow-up time was 4 (0.5 to 8.5) years. All cause-mortality rate was 3.85% (21 patients), and freedom MACCE was 72.2%. The freedom from MACCE, recurred angina and cerebral infarction were without significant difference, but AMI was associated with higher rate of PCI procedure. Conclusion CABG procedure in CAD patients under 45 years accompanied AMI is safety and reliable both in early and the long-term outcomes.
Radiation proctopathy, which can be categorized as acute and chronic, is defined as the radiation damage to the rectum caused by radiation therapy in patients with pelvic malignancies. Chronic radiation proctopathy can cause complications such as rectal bleeding, which severely affects patients’ quality of life. At present, endoscopic therapy has become the primary method for diagnosis and treatment of bleeding from chronic radiation proctopathy. In October 2019, the American Society for Gastrointestinal Endoscopy (ASGE) published "ASGE guideline on the role of endoscopy for bleeding from chronic radiation". The guideline described the effectiveness and safety of different endoscopic therapies such as argon plasma coagulation, bipolar electrocoagulation, heater probe, radiofrequency ablation, cryoablation, etc. in the treatment of bleeding from chronic radiation. This paper interprets it to provide references for clinicians in the treatment of bleeding from chronic radiation.
