Objective:To retrieve, evaluate and integrate the evidence related to the preparation process for initiating extracorporeal cardiopulmonary resuscitation in hospital, so as to provide reference for clinical implementation of extracorporeal cardiopulmonary resuscitation.Methods:According to the evidence-based nursing method and the 6S evidence model, guidelines, clinical decisions, expert consensus, systematic review and other literatures related to the preparation process for initiating extracorporeal cardiopulmonary resuscitation in hospital were searched from National Guideline Clearinghouse, Scottish Intercollegiate Guidelines Network, National Institute for Health and Care Excellence, and other websites, UpToDate, The Cochrane Library, PubMed, Embase, CNKI, Wanfang and other databases. The retrieval date limit was from the establishment of the database to May 20, 2023. Researchers assessed the quality of the included articles, and extracted and summarized the evidence that met the quality standards.Results:A total of 11 articles were included, including 2 guidelines, 6 expert consensuses, 1 systematic review and 2 quasi-experimental studies. A total of 18 pieces of evidences were summarized from 6 aspects, including medical conditions, team building, materials management, operation mechanism, pre-initiating treatment and initiating judgment.Conclusions:This study summarizes the evidence of preparation process for initiating extracorporeal cardiopulmonary resuscitation in hospital, which can provide reference for promoting the implementation of extracorporeal cardiopulmonary resuscitation. Future studies still need to focus on team building, personnel training and assessment, and optimisation of the management system, so as to improve the efficiency and readiness of treatment.

Objective:To explore the therapeutic effect of traditional Chinese medicine formula Kuijie enema combined with Western medicine on patients with ulcerative colitis.Methods:A clinical prospective randomized trial was conducted, and 107 patients with ulcerative colitis admitted to the Shiyan People′s Hospital from January 2018 to December 2022 were included in the study. They were randomly divided into a combination group of 54 cases and a control group of 53 cases using a random number table method. Both groups of patients received the same basic treatment plan, and the combination group was treated with traditional Chinese medicine formula for ulcerative colitis enema on this basis. Both groups of patients were treated continuously for 4 weeks, We observed the differences in serum inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-10 (IL-10), monocyte chemokine 1 (MCP1)], Mayo score, endoscopic mucosal score, traditional Chinese medicine symptom score, and clinical treatment efficacy between two groups of patients before and after treatment.Results:After treatment, the serum levels of TNF-α, IL-6, and MCP1 in the two groups were lower than those before treatment, and IL-10 was higher (all P<0.05), and the changes of the above inflammatory factors were more obvious in the combined group, with statistically significant differences (all P<0.05). After treatment, the Mayo score and endoscopic mucosal score of both groups of patients decreased compared to before treatment (all P<0.05), and the Mayo score and endoscopic mucosal score of patients in the combination group were lower than those in the control group (all P<0.05). After treatment, the traditional Chinese medicine syndrome scores of both groups decreased compared to before treatment (all P<0.05), and the combined group patients had lower scores for diarrhea, abdominal pain, pus and bloody stools, urgency and weight, and anal burning than the control group, with statistical significance (all P<0.05). Both groups of patients were treated continuously for 4 weeks, and the overall efficacy distribution of the combination group was better than that of the control group ( Z=-2.274, P=0.023). Conclusions:The combination of traditional Chinese medicine formula Kuijie enema liquid and Western medicine can more effectively reduce the degree of inflammation in patients with ulcerative colitis, alleviate clinical symptoms, and improve clinical treatment effectiveness.

Objective·To explore the predictive value of diuretic renal scintigraphy parameters such as 20-minute residual rate(R20)for pyeloplasty in children with congenital unilateral ureteropelvic junction obstruction(UPJO).Methods·The clinical data and diuretic renal scintigraphy results of 110 children with congenital unilateral UPJO who were first treated at the Department of Nuclear Medicine,Xinhua Hospital,Shanghai Jiao Tong University School of Medicine from August 2018 to August 2023 were retrospectively analyzed.The imaging results and the progress of hydronephrosis were followed up after the first diuretic renal scintigraphy.According to the outcome event of pyeloplasty due to the progression of hydronephrosis,the children were divided into operation group and non-operation group.Age,gender,side of hydronephrosis,and baseline diuretic renal scintigraphy parameters including blood perfusion rate(BPR),differential renal function(DRF),time to peak(Tmax),time to half(T1/2)and R20 were compared between the two groups.Logistic regression was used to analyze the effect of various parameters on the progression of hydronephrosis.The receiver operating characteristic(ROC)curve was used to analyze the predictive value of diuretic renal scintigraphy parameters for surgical intervention.Wilcoxon test was used to compare the examination parameters of two diuretic renal dynamic imaging.Results·During the follow-up,60 children underwent pyeloplasty after progression,and the other 50 children did not progress.The differences in DRF,Tmax,T1/2 and R20 between the two groups of children at baseline were statistically significant(all P<0.05).Univariate and multivariate Logistic regression analysis showed that only R20 was an independent predictor of pyeloplasty(OR=4.730,95%CI 1.009-1.178,P=0.030).R20 predicted pyeloplasty with a sensitivity of 88.3%,specificity of 56%,the area under the ROC curve of 0.758(95%CI 0.667-0.850,P=0.000),and the cut-off value of 90.08%.During the follow-up,38 children underwent the second diuretic renal scintigraphy,and the DRF was lower than before.The difference between the two DRFs was statistically significant(Z=-2.589,P=0.010),especially in children with R20≥90.08%(Z=-2.166,P=0.030).R20 in the non-operation group decreased significantly compared with the baseline(Z=-2.062,P=0.039).However,R20 in the operation group was higher than baseline,but the difference was not statistically significant(P>0.05).Conclusion·R20 plays an important role in the prediction of pyeloplasty in children with congenital unilateral UPJO.For children with R20≥90.08%,pyeloplasty should be performed as soon as possible to prevent further deterioration of renal function.

Objective To observe the effect of cluster emergency nursing in treating patients with chlorfenapyr poisoning. Methods A retrospective analysis was performed for the treatment and nursing processes of 6 patients with chlorfenapyr poisoning. Results Among the 6 patients with chlorfenapyr poisoning, 5 cases were orally poisoned and one case was poisoned by respiratory tract and skin absorption of toxins. All of the 6 patients with chlorfenapyr poisoning were treated through the green channel for poisoning treatment, and multidisciplinary cooperation cluster treatment and nursing as well as toxicant detection were carried out. One patient was excluded because no chlorfenapyr component was detected in the toxicant detection; the remaining 5 patients had different degrees of fever, fatigue, nausea and vomiting and other symptoms in the early stage, and among them, 4 patients had high fever and aggravated degree of consciousness disturbance in the later stage of the disease, and died of ineffective treatment for 2 to 11 days after poisoning (one patient was out of contact and was expected to die), with a mortality rate of 80%. Conclusion There is no specific antidote for chlorfenapyr poisoning, and the mortality rate is extremely high. After poisoning, blood, urine and other specimens should be collected as soon as possible for toxic examination. At the same time, early gastric lavage (within 6 hours), intestinal adsorption, gastrointestinal catharsis, enema and other symptomatic treatments should be given. Continuous blood purification should be performed as soon as possible to remove blood toxins, and extracorporeal membrane oxygenation can be performed if conditions permit.

Objective:To explore the diagnostic value of the toxicant and drug detection in clinical poisoning diseases and analyze the clinical characteristics of patients with positive poison test.Methods:This study was a multicenter retrospective cohort study. Sampling and clinical information data were collected between October 1, 2020 and September 30, 2022 from 41 tertiary hospitals in and around Jiangsu province. The clinical characteristics of patients with positive toxicology tests were analyzed, and the correlation between the drug sampling situation and the test results was analyzed..Results:A total of 895 patients with clinical diagnosis or suspected poisoning were enrolled in this study. Among them, 652 patients had positive results, accounting for 72.85%. Among all positive patients, 506 patients were exposed to a single poison and 147 patients were exposed to multiple poisons. The top three poisons were pesticide herbicides (202 cases, 30.98%), sedative and psychotropic drugs (151 cases, 23.16%), and pesticide insecticides (97 cases, 14.88%). Among 541 patients with clear exposure history, the positive rate was 78.19%, and among 354 patients with unclear exposure history, the positive rate was 64.69%. The top three poisons (drugs) of patients with unclear exposure history were sedative and psychotropic (82, 12.58%), herbicide (26, 3.99%), and rodenticide (22, 3.37%). Patients who admitted to hospital for unexplained consciousness disorder, abnormal blood coagulation function and multiple organ dysfunction were more likely to obtain positive poison test results.Conclusions:There is uncertainty in the exposure history of poisoning diseases, so it is necessary to improve the detection of toxic substances as soon as possible. Toxicant testing should be considered when patients have impaired consciousness, abnormal coagulation function and multiple organ dysfunction.

Objective:To explore the application effect of continuous quality improvement based on trauma team activation model in emergency triage.Methods:This study is a historical controlled study. A total of 12 215 trauma patients receiving initial treatment in the Emergency Department of the First Affiliated Hospital with Nanjing Medical University from January 2020 to June 2021 were selected as the research objects by the convenience sampling method, and 3 896 trauma patients from January to June 2020 were enrolled as the baseline group, and 4 054 patients from July to December 2020 were enrolled as the phaseⅠ improvement group, and 4 265 patients from January to June 2021 were enrolled as the phaseⅡ improvement group. The baseline group adopted the one-tiered trauma team activation model, which was evaluated and decided by the first-visiting doctor. The phaseⅠ improvement group received the one-tiered trauma team activation model, which was evaluated and decided by pretest triage nurses. The stageⅡ improvement group conducted the two-tiered trauma team activation model, which was evaluated and decided by pretest triage nurses. The trauma team activation time, overtriage rate and undertriage rate were compared between the three groups.Results:The trauma team activation time of the phaseⅠ improvement group and phaseⅡ improvement group was shorter than that of the baseline group, and the difference was statistically significant ( P<0.05). The overtriage rate of the phaseⅡ improvement group was lower than that of the baseline group and the phaseⅠ improvement group, and the differences were statistically significant ( P<0.05). The underage rate of the three groups were <5%, and the differences were not statistically significant ( P>0.05) . Conclusions:The two-tiered activation of trauma team mode led by nurses can shorten the trauma team activation time, reduce the overtriage rate and undertriage rate, improve the quality of trauma team activation.

Objective:To investigate the status quo of organizational silence behavior of nurses in Emergency Department, and analyze the influence of working environment and psychological capital on organizational silence.Methods:This study was a cross-sectional study. Using the convenient sampling method, a total of 232 emergency department nurses from 5 ClassⅢ Grade A hospitals in Jiangsu Province were selected as the research objects from April to June 2022. The research objects were surveyed using the general information survey questionnaire, Nurse Organization Silence Assessment Questionnaire, Nurse Work Environment Scale and Nurse Psychological Capital Scale. Pearson correlation was used to analyze the correlations among organizational silence, work environment and psychological capital. The mediation model was modeled using AMOS 24.0 software, and the Bootstrap method was used to verify the mediating effect of psychological capital between work environment and organizational silence. A total of 232 questionnaires were sent out in this study, and 210 were effectively received with effective recovery of 90.5% (210/232) .Results:The organizational silence score of 210 emergency department nurses was (54.70±15.02), The working environment score was (80.72±11.07), and the psychological capital score was (71.59±11.57). Organizational silence was negatively correlated with work environment and psychological capital scores ( r=-0.309, -0.670, respectively; P<0.05) ; Working environment was positively correlated with psychological capital score ( r=0.266, P<0.05). The mediating effect analysis showed that psychological capital had a partial mediating effect between working environment and organizational silence (β=-0.311, P<0.05). The direct effect size of working environment on organizational silence was -0.241 ( P<0.05) . Conclusions:The organizational silence of nurses in emergency department is at a medium high level, and the working environment can indirectly affect the organizational silence through psychological capital. Nursing managers can improve organizational silence by creating a healthy working environment, cultivating nurses' psychological capital and creating more opportunities to communication.

Objective:To confirm the efficacy and safety of cinepazide maleate injection in acute ischemic stroke patients with obvious motor function deficit.Methods:This study is a subgroup analysis of multi-center, randomized, double-blind, placebo-controlled phase Ⅳ clinical trial. A total 812 patients of acute ischemic stroke with obvious limb motor deficit [motor function of limbs score in National Institutes of Health Stroke Scale (NIHSS) ≥4] were enrolled in this subgroup analysis. Patients received either cinepazide maleate injection or placebo. The treatment period was 14 days and follow-up was 90 days. The efficacy endpoints included the proportions of patients with a modified Rankin Scale (mRS) score ≤2, mRS score ≤1 and Barthel Index <95 on day 90. Safety was evaluated by recording all adverse events, monitoring vital signs, laboratory parameters and electrocardiogram.Results:A total of 732 patients were involved in the final efficacy analysis (361 in cinepazide maleate group and 371 in control group). The baseline limb motor function score of NIHSS was 5.23±1.43 in the cinepazide maleate group whereas 5.20±1.36 in the control group. Logistic regression analysis showed that following treatment for 90 days, the proportion of patients with a mRS score ≤2 was significantly higher in the cinepazide maleate group than in the control group [56.0% (202/361) vs 44.2% (164/371), OR=0.60, 95% CI 0.44-0.82, P=0.002]. The proportion of patients with a mRS score ≤1 was higher in the cinepazide maleate group than in the control group [43.3% (139/361) vs 35.2% (118/371), OR=0.69, 95% CI 0.50-0.97, P=0.031]. The proportion of patients with a Barthel Index <95 on day 90 was significantly lower in the cinepazide maleate group than in the control group [45.2% (145/361) vs 55.2% (185/371), OR=0.64, 95% CI 0.46-0.88, P=0.007]. During the treatment and follow-up period, the incidence of the most common adverse events in the cinepazide maleate group was 50.4% (199/395). Constipation and abnormal liver function were more common, but there were no statistically significant differences between the two groups. Conclusion:Cinepazide maleate injection is superior to placebo in improving neurological function and activities of daily living, reducing disability, and promoting functional recovery and safe in patients with acute ischemic stroke with obvious limb motor deficit.

Objective:To investigate the predictive role of dynamic changes of plasma biomarkers in patients with viral and mycoplasma community-acquired pneumonia (CAP).Methods:From January 2020 to June 2020, 141 patients with viral and mycoplasma CAP in People's Hospital of Ningxia Hui Autonomous Region were enrolled. Pneumonia severity index (PSI) scores [grade Ⅰ-Ⅱ(PSI score ≤ 70), grade Ⅲ (PSI score 71-90) and grade Ⅳ-Ⅴ(PSI score ≥ 91)], serum amyloid A (SAA), hypersensitive C-reactive protein (hs-CRP), procalcitonin (PCT), erythrocyte sedimentation rate (ESR) and white blood cell (WBC) on the 1 day after admission were compared between the different pathogens (viral and mycoplasma) or different disease severity. The change in level of SAA, hs-CRP on the third day (Δ 3 d = 1 d-3 d) were compared among different disease outcome groups (patients were divided into improved group, stable group and exacerbation group based on PSI scores or lung CT images on the third day). The change in the level of SAA, hs-CRP on the seventh day (Δ 7 d = 1 d-7 d) were compared among different disease prognosis groups (patients were divided into survival group and death group based on 28-day survival data). The receiver operating characteristic curve (ROC) were drawn to evaluate the value of SAA in the evaluation of disease and prediction prognosis. Results:The level of SAA in mycoplasma group (43 cases) was significantly higher than that in virus group (98 cases) on the 1 day after admission. There were no significant differences in other plasma biomarkers between the two groups. The more severe the illness, the higher the SAA level on the 1 day after admission. The trends of other plasma biomarkers in the two groups were consistent with SAA. The levels of SAA in the patients with exacerbation of the virus group and mycoplasma group (12 cases, 9 cases) were significantly higher than those of the improved group (57 cases, 26 cases) and the stable group (29 cases, 8 cases). SAA increased gradually in the exacerbation group, decreased gradually in the improved group, and slightly increased in the stable group. ΔSAA 3 d were differences among three groups. The change trend of hs-CPR was consistent with SAA. The level of SAA in the death group was higher than that in the survival group on the seventh day. SAA increased in the death group and decreased in survival group with time from hospital admission. There were differences according to ΔSAA 7 d between death group and survival group. The change trend of hs-CPR was consistent with SAA. ROC curve showed that the value of SAA was better than hs-CRP in assessing the severity of patients on admission day, and the area under ROC curve (AUC) was respectively 0.777 [95% confidence interval (95% CI) was 0.669-0.886], 0.729 (95% CI was 0.628-0.830). The value of ΔSAA 3 d was better than SAA on the third day predicting disease trends, and AUC was respectively 0.979 (95% CI was 0.921-1.000), 0.850 (95% CI was 0.660-1.000). hs-CRP on the third day and Δhs-CRP 3 d had no predictive value. Both SAA on the seventh day and ΔSAA 7 d have predictive value for prognosis. AUC was respectively 0.954 (95% CI was 0.898-0.993) and 0.890 (95% CI was 0.689-1.000). SAA on the seventh day and ΔSAA 7 d were better than hs-CRP on the seventh day. Δhs-CRP 7 d have no predictive value. Conclusions:SAA is a sensitive and valuable indicator for CAP patients with viruses and mycoplasma. Dynamic monitoring of SAA can evaluate the patient's progression, prognosis, and assist diagnosis and treatment.

Objective:To investigate the blood pressure change in patients with acute ischemic stroke (AIS) and hypertension treated with cinepazide maleate injection.Methods:This was a subgroup analysis of post-marketing clinical confirmation study of cinepazide maleate injection for acute ischemic stroke: a randomized, double-blinded, multicenter, placebo-parallel controlled trial, which conducted in China from August 2016 to February 2019. Eligible patients fulfilled the inclusive criteria of acute anterior circulation ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores of 7-25. The primary endpoints were mean blood pressure of AIS patients treated with cinepazide maleate or control, which were assessed during the treatment period (14 days), and the proportion of the patients with normal blood pressure was analyzed after the treatment period. Furthermore, a subgroup analysis was performed to investigate a possible effect of the history of hypertension on outcomes.Results:This analysis included 809 patients with hypertension. There was no significant difference in patients blood pressure and the proportion of patients with normal blood pressure (60.5% vs. 59.0%, P>0.05) between cinepazide maleate group and control group. Conclusion:Administration of cinepazide maleate injection does not affect the management of clinical blood pressure in patients with AIS.
