Indwelling urinary catheterization is one of the most widely used invasive procedures in clinical practice, playing a critical role in disease diagnosis, treatment, and monitoring. In 2024, the European Association of Urology Nurses (EAUN) released the Best Practice Guidelines for Indwelling Urinary Catheterization in Adults-Transurethral and Suprapubic Catheterization (hereinafter referred to as the Guideline), aiming to provide evidence-based clinical guidance and health education information for healthcare professionals. This article interprets the section on "Nursing Principles" within the Guideline, which spans the entire process of catheter management. Key aspects covered include pre-insertion preparation, catheter insertion procedure, catheter maintenance and securement, observation of urine color, prevention of constipation, and catheter removal. The aim is to help urology nurses and related healthcare personnel gain an in-depth understanding of the recommendations in the Guideline, promote its standardized application in clinical practice, improve the quality of indwelling catheter care, and ensure patient safety.

Objective:To determine the median effective dose (ED 50) of oliceridine inhibiting responses to insertion of the gastroscope when combined with propofol in obese patients. Methods:In this prospective study, American Society of Anesthesiologists Physical Status classification I or Ⅱ patients of either sex, with a body mass index of ≥28 kg/m 2, undergoing elective painless gastroscopy, were selected. Propofol 1.5 mg/kg was slowly injected intravenously 2 min after intravenous injection of oliceridine. Gastroscopy was performed after the patient′s eyelash reflex disappeared and the jaw was relaxed. The optimal dose was determined by modified Dixon′s up and down method. The initial dose of oliceridine was 0.015 mg/kg, and the ratio between the two successive concentrations was 1.0∶1.2. If the patient had a positive response that affected the examination operation such as swallowing, bucking and body movement during insertion of the gastroscope, the next patient received a higher dose, or conversely if negative, a lower dose was given in the next patient. This process was repeated until the 7th turning point occurred. The ED 50 and 95% confidence interval of olicerdine inhibiting responses to insertion of the gastroscope were calculated by probit method. Results:A total of 21 patients were included in this study, the ED 50 of olicerdine inhibiting responses to implantation of the gastroscope was 0.016 mg/kg, and the 95% confidence interval was 0.010-0.023 mg/kg when combined with propofol 1.5 mg/kg in obese patients. One patient developed hypoxemia. One patient had mild dizziness after operation. Conclusions:The ED 50 of olicerdine inhibiting responses to implantation of the gastroscope is 0.016 mg/kg when combined with propofol 1.5 mg/kg in obese patients.

Objective Based on the three tools of the AGREE Next Steps Consortium(AGREE Ⅱ),China Clinical Guidelines Evaluation System(AGREE-China)and Scientificity Transparency Applicability Rankings(STAR),the methodological quality of Chinese medicine clinical treatment guidelines for coronary heart disease published by domestic institutions was systematically evaluated.Methods Computer system retrieval of China National Knowledge Infrastructure(CNKI),WanFang Data,Chinese Science and Technology Journal Database(VIP),China Biology Medicine(CBM)and Yimai Tong,and collect clinical practice guidelines of traditional Chinese medicine for coronary heart disease issued by domestic institutions(including expert consensus).The search period was from the establishment of the database to December 31,2023.Results A total of 21 guidelines were included.AGREE Ⅱ recommended 13 for grade A and 8 for grade B.The approval-China review strongly recommends 12,weakly recommends 8,and does not recommend 1.The highest STAR rating is a 4.0 star recommendation and the lowest is a 1.5 star recommendation.Conclusions There are a large number of TCM diagnosis and treatment guidelines and expert consensus on coronary heart disease in China,but the quality is uneven.It is suggested that the future guideline formulation should pay attention to the evidence-based principle,promote the standardization and standardization of the guideline formulation,and improve the scientific and applicability of the guideline.

[Objective]To investigate the clinical features and high risk of very preterm infants with late-onset bacteri-al sepsis,so as to propose feasible prevention and treatment suggestions.[Methods]Totally 94 very preterm infants with late-onset bacterial sepsis from the Neonatology Department of Women's Hospital of Jiangnan University were recruited from February,2012 to January,2024.Their clinical data,including the perinatal situation,clinical symptoms,patho-gens,risk factors and treatment,were collected and analyzed.[Results]The incidence rate of very preterm infants with late-onset bacterial sepsis were 8.40 for 100 live birth babies.The major pathogens of the infections among these very pre-mature infants included gram-positive bacteria(71.1%).Logistic regression analysis showed that long term(≥7 d)use of antibiotics,invasive mechanical ventilation,indwelling central venous catheter(≥7 d),and vaginal delivery were high risk factors of very preterm infants with late-onset bacterial sepsis,the relative risk(OR)values were 2.787,4.243,3.033 and 2.174,respectively.[Conclusion]The gram-positive bacteria are the main pathogens of late-onset bacterial sepsis in very preterm infants.Long term(≥7 d)use of antibiotics,invasive mechanical ventilation,indwelling central ve-nous catheter(≥7 d)and vaginal delivery are high risk factors of very preterm infants with late-onset bacterial sepsis.The incidence of late-onset bacterial sepsis in very preterm infants can be reduced by strengthening perinatal management,shortening the time of antibiotic application and reducing invasive operations.

Objective:To determine the median effective dose (ED 50) of oliceridine combined with propofol for analgesia during induced abortion in patients with different labor histories. Methods:This was a prospective study. American Society of Anesthesiologists Physical Status classification I or Ⅱ patients, aged 18-45 yr, with a body mass index of 20-28 kg/m 2, scheduled for elective induced abortion at Henan Provincial People′s Hospital (Zhengzhou University People′s Hospital) from July 1, 2024 to August 20, 2024, were selected. Patients were divided into a delivery group (group D) and a non-delivery group (group N) based on their histories of vaginal delivery. The modified Dixon′s up and down method was used to conduct the trial. Oliceridine was intravenously injected at a dose of 0.015 mg/kg in the first patient in each group, and the dose was determined based on the intraoperative body movement. The positive response was defined as the body movement of grade 2 or higher during induced abortion. If the response was positive, the next patient received a higher dose of oliceridine, or conversely, a lower dose was given. The ratio between the two successive concentrations was 1.2, and the trial was terminated until 7 turning points were achieved. The ED 50 and 95% confidence interval were calculated using the Dixon sequential method formula. The occurrence of adverse reactions was recorded. Results:A total of 54 patients were included in this study, with 25 in group D and 29 in group N. The ED 50 and 95% confidence interval of oliceridine for painless abortion were 0.019 (0.014-0.031) mg/kg and 0.026 (0.020-0.044) mg/kg in group D and group N, respectively. Compared with group D, the ED 50 of oliceridine for analgesia during induced abortion was significantly increased when combined with propofol in group N ( P<0.05). Patients in both groups experienced dizziness after intravenous oliceridine injection, and no other adverse reactions such as injection pain were observed. Conclusions:When combined with propofol, the ED 50 of oliceridine for analgesia is 0.019 mg/kg and 0.026 mg/kg during induced abortion in patients with and without vaginal delivery history, respectively. The analgesic potency of oliceridine is decreased in patients without a history of vaginal delivery compared to patients with a history of vaginal delivery.
