Objective: To investigate the coping styles and subjective well-being of nurses in the emergency treatment room of grade A tertiary hospitals in a province of China, and to explore the relationship between coping styles and subjective well-being. Methods: In January 2016, 189 nurses in the emergency treatment room were selected from 9 grade A tertiary hospitals in a province of China by random sampling. The general data, coping styles, and subjective well-being of these nurses were analyzed using the general questionnaire, coping style questionnaire, and Campbell index of well-being scale, respectively. Results: The total score of subjective well-being of nurses in the emergency treatment room was 7.54, and the subjective well-being was significantly different between the nurses with different professional titles and between those with different education levels (F=3.46 and 3.47, both P<0.05). The score of illusion coping style differed significantly across the nurses of different ages (F=5.17, P<0.05) , the scores of self-reproach, illusion, and withdrawal coping styles differed significantly across the nurses with different nursing years (F=3.99, 5.30, and 4.97, all P<0.05) , and the score of illusion coping style differed significantly across the nurses with different education levels (F=5.09, P<0.05). Most (71.9%) of the nurses in the emergency treatment room adopted the mature coping style. Subjective well-being was positively correlated with problem-solving, help-seeking, and rationalization (r=0.232, 0.018, and 0.167, all P<0.05) and negatively correlated with withdrawal (r=-0.146, P<0.05) . Conclusion Most nurses in the emergency treatment room adopt the mature coping style. Their subjective well-being and coping style vary with different ages, nursing years, professional titles, and education levels, and the subjective well-being is relatively low.

Intravenous infusion is an important route of drug therapy, and infusion safety is an important issue for medical staff. Long-term and multiple infusion routes at the same time bring inconvenience to patients. Multiple three-way switches in parallel infusion may lead to interruption of the liquid route, which can seriously endanger the life of patients. To address these clinical issues, medical staff from the School of Basic Medical Sciences of Hebei Medical University and the Emergency Department of the Second Hospital of Hebei Medical University designed a multiple combination portable infusion assistance device and obtained the National Utility Model Patent of China (ZL 2022 2 0226073.2). The device is mainly composed of adhesive tape sticker, fixed slots and pipelines, and also includes a three-way valve and a mixing chamber, and different modes of infusion assist devices can be selected according to clinical needs. The device is simple and convenient to operate, solves the problem of multiple liquid infusion blockages, improves the safety and comfort of infusion, and can meet the needs of liquid infusion in various clinical situations.

Objective:To investigate the in-hospital diagnosis and treatment time for patients with acute ischemic stroke in Hebei Province.Methods:The data of in-hospital diagnosis and treatment of acute ischemic stroke in Hebei Province were collected and analyzed, and then compared with the NINDS recommended time. Methods The data of in-hospital diagnosis and treatment of acute ischemic stroke in Hebei Province were collected and analyzed, and then compared with the NINDS recommended time.Results:The median time in hospital diagnosis and treatment was significantly longer than the NINDS recommended time (104 min vs. 60 min, P<0.001). The median time from completing the cranial CT scan to getting the CT report differed significantly to the NINDS recommended time (30 min vs. 20 min, P<0.001). The median time from getting the CT report to obtaining treatment was 43 min, which was significantly longer than the NINDS recommended 15 min ( P<0.001). The median time of in-hospital diagnosis and treatment for emergency service system (EMS) patients was 101 min, which was shorter than that for non-EMS patients (104 min, P=0.01). The median time of in-hospital diagnosis and treatment in Tertiary Hospital was 105 min, which was significantly longer than that in Secondary Hospital 99 min, ( P<0.05). Conclusions:The in-hospital emergency treatment delay in Hebei Province was relatively serious for patients with acute ischemic stroke. The time between obtaining the head CT report to beginning thrombolytic therapy is the most important factor in hospital delay. EMS can shorten in-hospital delay for acute ischemic stroke. Compared with the tertiary hospital, the secondary hospital has shorter in-hospital delay time.

Objective:To explore the selection of strategies for early reperfusion therapy and its impact on prognosis in patients with acute ST segment elevation myocardial infarction (STEMI).Methods:The treatment data and 3-year follow-up results of acute myocardial infarction (AMI) patients in 49 hospitals in Hebei Province from January to December 2016 were collected. Patients with STEMI who received either intravenous thrombolytic therapy (ITT) or primary percutaneous coronary intervention (PPCI) within 12 hours of onset were enrolled. Baseline data, the time from the first diagnosis to the start of reperfusion (FMC2N for ITT patients and FMC2B for PPCI patients), vascular recanalization rate, in-hospital mortality, 1-year mortality, and 3-year mortality were compared between ITT and PPCI groups. The efficacy and prognosis of ITT and PPCI at different starting time of reperfusion (FMC2N≤30 minutes, FMC2N > 30 minutes, FMC2B≤120 minutes, FMC2B > 120 minutes) were analyzed.Results:A total of 1 371 STEMI patients treated with ITT or PPCI were selected, including 300 patients in the ITT group and 1 071 patients in the PPCI group. 1 055 patients were actually followed up (205 patients in the ITT group and 850 patients in the PPCI group), with a rate of 79.4%. There were no significant differences in age, gender, and previous history between the two groups. The time from the first diagnosis to the start of reperfusion in the ITT group was shorter than that in the PPCI group [minutes: 63 (38, 95) vs. 95 (60, 150), U = -9.286, P = 0.000], but was significantly longer than the guideline standard. Compared with the ITT group, the vascular recanalization rate in the PPCI group was higher [95.5% (1 023/1 071) vs. 88.3% (265/300), P < 0.01], and in-hospital mortality was lower [2.1% (22/1 071) vs. 6.7% (20/300), P < 0.01], but there were no significant differences in the 1-year mortality and 3-year mortality [5.3% (45/850) vs. 4.4% (9/205), 9.5% (81/850) vs. 9.3% (19/205), both P > 0.05]. Between ITT group and PPCI group with different reperfusion starting time, the FMC2N > 30 minutes group had the lowest vascular recanalization rate and the highest in-hospital mortality. Pairwise comparison showed that the vascular recanalization rate of the FMC2B ≤ 120 minutes group and the FMC2B > 120 minutes group were significantly higher than those of the FMC2N > 30 minutes group [95.5% (654/685), 95.6% (369/386) vs. 88.0% (220/250), both P < 0.008], the in-hospital mortality was significantly lower than that of the FMC2N > 30 minutes group [2.0% (14/685), 2.1% (8/386) vs. 7.6% (19/250), both P < 0.008]. There was no significant difference in 1-year mortality (χ 2 = 2.507, P = 0.443) and 3-year mortality (χ 2 = 2.204, P = 0.522) among the four groups. Conclusions:For STEMI patients within 12 hours of onset, reperfusion therapy should be performed as soon as possible. PPCI showed higher infarct related artery opening rate and lower in-hospital mortality compared with ITT, and had no effect on 1-year and 3-year mortality.

In order to improve the clinical attention to the poisoning of chlorfenapyr, the diagnosis and treatment strategy of chlorfenapyr poisoning were discussed. This paper collected 4 cases of chlorfenapyr in the emergency department of the Second Hospital of Hebei Medical University and 4 cases of literature review, summarized the clinical characteristics of pesticide poisoning cases containing chlorfenapyr in China, and summarized and analyzed the clinical data of the cases. Seven of the 8 patients died from poisoning by chlorfenapyr. Exposure to chlorfenapyr through respiratory tract and digestive tract showed high mortality. Fever, hyperhidrosis, elevated muscle enzymes and progressive central nerve damage were its prominent clinical characteristics. Most of the initial symptoms of exposure were not serious. Some patients, especially those with low exposure dose, had a relatively stable stage with or without clinical diagnosis and treatment. In case of sweating, obvious fever and disturbance of consciousness, the condition would deteriorate rapidly, respiratory and circulatory failure and eventually die. With the increase of production capacity and market launch, people have more opportunities to be exposed to chlorfenapyr. It is urgent to strengthen the basic and clinical research of chlorfenapyr poisoning; Attention should be paid to the observation and treatment in the initial stable stage of poisoning, which can be used as a reference for the treatment of oxidative phosphoric acid dissolving coupling agent (sodium pentachlorophenol) poisoning.

Objective To analyze the prognosis and influencing factors of patients with acute myocardial infarction(AMI)complicated with cardiogenic shock(CS)under extracorporeal membrane oxygenation(ECMO)support.Methods Retrospective analysis of the clinical data of ECMO supported coronary angiography and percutaneous coronary intervention(PCI)treatment for AMI complicated with CS patients who visited the department of emergency medicine of the Second Hospital of Hebei Medical University from December 2018 to December 2021,including gender,age,body mass index(BMI),past history(smoking history,coronary heart disease,diabetes,hypertension,hyperlipidemia,cerebrovascular disease),acute physiological and chronic health evaluationⅡ(APACHEⅡ),vasoactive-inotropic score(VIS),the worst auxiliary examination indicators within 24 hours before ECMO[arterial lactate acid,white blood cell count(WBC),cardiac troponin I(cTnI),alanine transferase(ALT),total bilirubin(TBil),creatinine(Cr),serum potassium(K+),left ventricular ejection fraction(LVEF)],time from onset to PCI,coronary angiography results(involved anterior descending branch,circumflex branch,right coronary artery,three-vessel lesions,left main artery lesions),whether to use intra aortic-balloon counterpulsation(IABP)and continuous renal replacement therapy(CRRT).Patients were divided into survival and death groups based on the prognosis after 30 days of onset.Univariate analysis was used to compare the differences in the above indicators between the two groups with different prognoses,Logistic regression analysis was used to analyze the independent risk factors affecting the prognosis of AMI patients with CS under ECMO support coronary angiography and PCI treatment,and the receiver operator characteristic curve(ROC curve)was drawn to evaluate the predictive value of risk factors on patient prognosis.Results Out of 39 patients,21 cases(53.8%)survived and 18 cases(46.2%)died.Compared with the survival group,the VIS score,lactate acid,time from onset to PCI,involvement of the circumflex artery,three-vessel disease,and left main artery lesions significantly increased in the death group(all P＜0.05).Logistic regression analysis showed that lactate acid and three-vessel lesions were independent risk factors affecting the 30-day prognosis of AMI patients with CS[odds ratio(OR)and 95%confidence interval(95%CI)were 1.845(1.018-3.342)and 107.171(1.307-8 785.901),all P＜0.05].ROC curve analysis showed that lactate acid and three-vessel lesions has predictive value for the prognosis of AMI combined with CS patients undergoing ECMO supported coronary angiography and PCI treatment,the area under the ROC curve(AUC)were 0.756 and 0.752,95%CI were 0.601-0.911 and 0.588-0.916,P value were 0.007 and 0.008.When the cut-off value of lactic acid was 5 mmol/L,the sensitivity and specificity of predicting the prognosis of AMI combined with CS patients undergoing coronary angiography and PCI treatment were 94.1%and 57.1%,respectively.Conclusions The indications for using ECMO in critically ill patients with AMI combined with CS need to be further refined.VIS score,lactate acid,time from onset to PCI,three-vessel lesions,and left main artery lesions are risk factors for patient death.When using ECMO support for high lactate,high VIS score,and three-vessel lesions,caution should be exercised.Early ECMO support can improve the prognosis of appropriate patients by reducing lactate,reducing the use of vasoactive drugs,and shortening the time from onset to PCI.

Objective To evaluate the feasibility of emergency percutaneous coronary intervention(PCI)with extracorporeal membrane oxygenation(ECMO)support in critically ill patients with acute myocardial infarction(AMI)and cardiogenic shock(CS).Methods Retrospective analysis of clinical data of AMI combined with CS patients admitted to the department of emergency of the Second Hospital of Hebei Medical University from December 2018 to December 2021,including gender,age,body mass index(BMI),past history(smoking,coronary heart disease,arrhythmia,diabetes,hypertension,hyperlipidemia,cerebrovascular disease);acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)score,highest vasoactive-inotropic score(VIS)within 24 hours of admission,the worst auxiliary examination values within 24 hours after admission:blood lactic acid(Lac),arterial partial pressure of oxygen(PaO2),cardiac troponin I(cTnI),alanine aminotransferase(ALT),total bilirubin(TBil),creatinine(Cr),serum potassium,left ventricular end-diastolic diameter(LVEDD),left ventricular ejection fraction(LVEF)],presence of malignant arrhythmia or cardiac arrest during emergency PCI,completion of PCI,and the 30-day prognosis,etc.Patients were divided into an ECMO group and a non-ECMO group based on whether ECMO was applied,to analyze differences in the above indicators between the two groups.Results There were no statistically significant differences between the ECMO group and the non-ECMO group in terms of gender,age,BMI,past history,APACHEⅡ,VIS and the worst auxiliary examination value within 24 hours after admission.The incidence of malignant arrhythmia or cardiac arrest events and 30-day mortality rate during emergency PCI in the ECMO group were significantly lower than those in the non-ECMO group[the incidence of malignant arrhythmia or cardiac arrest during emergency PCI was 17.9％(7/39)vs.45.0％(9/20),and the 30-day mortality was 46.2％(18/39)vs.75.0％(15/20),both P<0.05].The completion rate of PCI in the ECMO group was significantly higher than that in the non-ECMO group[100.0％(39/39)vs.80.0％(16/20),P<0.05].Conclusions For critically ill patients with AMI combined with CS,ECMO support can reduce the risk of malignant arrhythmia or cardiac arrest during emergency PCI,increase the completion rate of PCI,and reduce the 30-day mortality.With the support of the ECMO team,ECMO support emergency PCI is feasible.

Objective: To investigate the application of emergency medical service (EMS) of Hebei Province and preliminarily analyze its value in the treatment of acute stroke patients. Methods: We collected data of 4 147 acute stroke patients admitted to the Emergency Department between January 2016 and December 2016 in 49 hospitals of Hebei Province. Patients were divided into the EMS group and non-EMS group according to the pattern of arriving hospital. The general data, the onset-to-door time, door-to-treatment time, thrombolytic rate, length of hospital stay and prognosis were compared between the two groups. LSD-t test, Mann-Whitney U or Chi-squared test or Fisher exact test was used for statistical analysis as appropriate. Results: A total of 4 147 acute stroke patients were enrolled, including 589 patients (14.2%) with hemorrhagic stroke and 3 558 patients (85.8%) with ischemic stroke. A total of 750 patients (18.1%) were admitted to the hospital by EMS. The proportion of patients with hemorrhagic stroke who used EMS was higher than that of ischemic stroke (33.4% vs 15.5%, P<0.01). The median onset-to-foor time in the EMS group was less than that in the non-EMS group (1.75 h vs 4.57 h, P<0.01). The median time of onset-to-door time within 1 h in the EMS group was longer than that of the non-EMS group (0.67 h vs 0.53 h, P<0.01). There was no significant difference between the two groups in 1-<2 h period and 2-<3 h period. The median time of onset-to-door time of ≥3 h in the EMS group was shorter than that of the non-EMS group (5.0 h vs 9.47 h, P<0.01). In the EMS group, the proportion of patients with onset-to-door time <3 h was higher than that of the non-EMS group (66.13% vs 57.44%, P<0.01). Compared with the non-EMS group, the time of door-to-treatment time was much shorter in the EMS group (87 min vs 101 min, P<0.01). The length of hospital stay in the EMS group was shorter than that of the non-EMS group [11 (7,14) days vs 12 (6,16) days, P<0.01]. In the EMS group, 15.9% patients received thrombolytic therapy, whereas only 11.0% patients in the non-EMS group received this therapy (P=0.001). In the EMS group, 88.8% patients achieved more favorable outcomes at discharge, which was higher than that in the non-EMS group (85.5%, P=0.02). Conclusions EMS is considered as effective in shortening onset-to-door time, reducing door-to-treatment time, improving thrombolytic rate, reducing hospitalization days, and enhancing the prognosis of acute stroke patients.
