Objective:Investigating the content and signing status of the informed consent form for surgery,as well as the signing status of the power of attorney to understand the current implementation of informed consent for surgery in medical institutions.Methods:A stratified random sampling method was used to investigate the signing status of surgical consent and power of attorney on 276 surgical records from a tertiary A hospital in the first half year of 2022.Results:The signatures of both patients and doctors were relatively complete.The medical teams had provided sufficient information to patients regarding the main preoperative diagnosis,surgical name,possible complications during or after the surgery,and surgical risks.However,there was inadequate information on the patient's own high-risk factors,as well as alternative treatment plans and their advantages and disadvantages.The signing of surgical consent and power of attorney signed by non-patients was not standardized.Conclusion:The implementation of informed consent for surgery in medical institutions is relatively good,but there are still some shortcomings.Medical institutions can ensure the implementation of informed consent by strengthening legal and regulatory training,clarifying the scope of authorization,strengthening the surgeon's notification and signing,as well as implementing supervision and inspection,so as to protect the unity of rights and obligations of doctors and patients,effectively avoid medical risks,and promote the construction of a harmonious doctor-patient relationship.

Objective:To investigate the prognostic factors of severe patients with bloodstream infection (BSI) caused by Enterobacteriaceae bacteria. Methods:Patients suffered from BSI caused by Enterobacteriaceae bacteria admitted to department of critical care medicine of Binzhou Medical University Hospital from October 2016 to October 2019 were enrolled. The information of gender, age, combined shock, acute physiology and chronic health evaluationⅡ(APACHEⅡ), sequential organ failure assessment (SOFA), sensitivity of initial antibiotics, as well as the baseline of procalcitonin (PCT), white blood cell count (WBC), platelet (PLT), albumin (ALB) were collected. The 72-hour PCT clearance rate (72 h PCTc) was calculated after 72 hours' treatment. According to the clinical outcome after 28 days, the patients were divided into recovery group and death group. The differences of clinical indicators between the two groups were compared, and then the statistical significant variables were further performed by Logistic regression to analyze the factors affecting the prognosis of patients. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive efficacy of the factors in severe BSI. Results:A total of 86 patients were enrolled, among whom 54 cases recovered while 32 cases died, and the 28-day mortality was 37.2%. There was no significant difference in gender, age, sensitivity of initial antibiotics, baseline levels of PCT and WBC between two groups. In the death group, the shock incidence, APACHEⅡscore, SOFA score were significantly higher than those in recovery group [shock incidence: 84.4% (27/32) vs. 46.3% (25/54), APACHEⅡ: 24.94±7.65 vs. 17.02±6.57, SOFA: 11.00±3.27 vs. 6.30±2.65, all P < 0.01]; the PLT and ALB baseline levels, 72 h PCTc were significantly lower than those in recovery group [PLT (×10 9/L): 73.38±49.15 vs. 138.69±101.80, ALB (g/L): 25.47±5.91 vs. 28.59±4.53, 72 h PCTc: -44 (-170, 27)% vs. 63 (40, 77)%, all P < 0.01]. The above 6 variables were included in Logistic regression. The results showed that SOFA score was a risk factor for death in these patients [odds ratio ( OR) = 1.930, P = 0.037], while 72 h PCTc and ALB were protective factors ( OR values were 0.043, 0.783, P values were 0.008, 0.047). The SOFA, 72 h PCTc and ALB can be used to predict the prognosis of severe BSI, and the diagnostic value of the combination of three factors was the largest [area under the ROC curve (AUC) = 0.953, 95% confidence interval (95% CI) was 0.909-0.997], the sensitivity was 100%, and the specificity was 79.6%. Conclusions:Severe patients with BSI caused by Enterobacteriaceae bacteria had a high mortality. Higher SOFA score, and lower ALB and 72 h PCTc predicted the adverse outcome. The combination of the three factors has the greatest prognostic efficacy.

Objective To explore impact of nursing intervention on the adverse reaction of patient con-trol epidural analgesia (PCEA) after abdominal operation. Methods 258 patients underwent PCEA after ab-dominal operation were selected from 2006 to 2007. The clinical data of 126 patients without nursing interven-tion were analyzed as the control group admitted to our hospital from January to December, 2006 and compared with those of 132 patients receiving nursing intervention as the experimental group from January to December, 2007. The control group was managed by the anesthetists and nurses only conducted routine nursing instruction, while the experimental group was given systematic and normative nursing intervention besides routine nursing instructions, including psychological intervention, behavioral intervention, close observation, of discovery of ad-verse reaction in time and giving early disposal. The incidence of adverse reaction of PCEA of the two groups such as urinary retention, nausea and vomiting, abdominal distension, skin indentation, catheter shedding, skin itching, numbness of lower limbs, respiratory depression was observed. Results Compared with the control group,the incidence of adverse reactions of PCEA in the experimental group such as urinary retention,nansea and vomiting, abdominal distension,skin indentation,catheter shedding was significantly lower. Conclusions The implementation of nursing intervention can reduce the adverse reaction of PCEA after abdominal operation, alle-viate the suffering of patients, and promote functional recovery and the body rehabilitation.

Objective To summarize the operative experience of ventricular septal defect(VSD) with severe pulmonary hypertension(PH).Methods 37 patients with VSD complicated with severe PH,who underwent surgical repair were treated combinatively in perioperative period including resting,oxygen inhalation,and administration of captoprill and prostaglandin E 1(PGE 1).All of the patients were operated by cardiopulmonary bypass with moderate hypothermia.Arterial oxygen saturation(SaO 2),pulmonary arterial pressure and cardiac function were observed before and after operation,and progression of cardiac function and mortality were followed-up after discharged.Results 2 patients died of low cardiac output syndrome(LCOS) and one patient died of respiratory failure,and the operative mortality was 8 1%.one patient was diad after 8 months and the cardiac function of 33 patients markedly improved.Conclusions Reasonable treatment in perioperative period and holding the indications for the operation strictly are the keys to decrease the mortality of the operation,and SaO 2 could be a simple measurement to identify the indication of operation and the prognosis of the patient with VSD complicated with severe PH.
