Objective:To explore the current status of discharge planning of ward nurses in cardiovascular department and analyzed influencing factors, and to provide reference for intervention strategies to build the discharge planning ability of the responsible nurses in cardiovascular department.Methods:This study was a cross-sectional survey. Convenience sampling method was adopted to select 267 ward nurses of cardiovascular department from 5 first-class hospitals in Dalian City from July to August 2022 as the research objects. The questionnaire survey was conducted by general data questionnaire, Job-Esteem Scale for Nurses in Hospital and Discharge Planning of Ward Nurses. Multiple linear regression analysis and Pearson correlation analysis were used for data analysis.Results:The total score of discharge planning of ward nurses in cardiovascular department was (103.86 ± 16.20) points; the total score of nurses' professional respect was (98.92 ± 13.67) points, and the total score of discharge planning of ward nurses in cardiovascular department was positively correlated with the total score of job-esteem and scores of all dimensions ( r values were 0.382-0.551, all P<0.01). Multiple linear regression analysis showed that age, professional title, certificate of cardiovascular nurses and job-esteem of nurses were influencing factors of discharge planning of ward nurses in cardiovascular department ( t values were 2.57-8.27, all P<0.05), accounting for 47.3% of the total variation. Conclusions:The discharge planning of ward nurses in cardiovascular department was above the medium level, and age, professional title, whether they were cardiovascular nurses and job-esteem were the influencing factors. From the perspective of improving nurses' job-esteem, nursing managers can focus on young nurses and nurses with low professional titles, attach importance to the training of specialized ward nurses in cardiovascular department, and take certain countermeasures to improve the discharge planning of ward nurses in cardiovascular department.

This article reviews the concept, evaluation criteria, current situation, influencing factors and the impact on health of intrinsic capacity in the elderly at home and abroad, in order to provide reference for clinical medical staff to improve the elderly′s intrinsic capacity, and actively carry out targeted interventions and related research.

This article reviews the current research status of nutritional literacy in chronic disease patients from four aspects, including the concept and connotation of nutritional literacy, evaluation tools for nutritional literacy of chronic disease patients, influencing factors and intervention strategies, so as to provide theoretical basis for medical staff to improve the nutritional literacy of chronic disease patients and to provide reference for future research on the nutritional literacy of chronic disease patients.

Extracorporeal membrane oxygenation(ECMO),an effective extracorporeal circulation support system,holds significant importance in the treatment of severe cardiovascular and pulmonary diseases.Effective fixation of ECMO catheters can prevent adverse events such as displacement and accidental extubation,thereby ensuring the effectiveness and continuity of ECMO treatment.At present,various tools such as transparent dressings,surgical dressings,and bandages are commonly used in clinical practice.However,there are problems such as insufficient fixation,unattractive and tidy appearance,and inconvenient replacement.There is still a lack of specific and effective dressings to fix ECMO catheters.Therefore,the medical staff from department of critical care medical of Hospital of Chengdu University of Traditional Chinese Medicine designed ECMO dressing,and obtained the National Utility Model Patent of China(patent number:ZL 202120543021.3),which includes 3 parts:upper dressing,middle dressing,and lower dressing with weak connections in sequence.The top surface of the upper dressing is the upper dressing layer,which is marked with a first scale.The middle part of the bottom surface of the upper dressing layer is fixed with a gauze layer.The top surface of the middle dressing is the middle dressing layer,and the bottom surface of the middle dressing layer is fixedly equipped with a mesh layer along the edges of the 2 length directions.There is a cutting gauze between the 2 mesh layers,and the 2 length edges of the cutting gauze are fixedly connected to the mesh layer.There is a plastic film between the cutting gauze and the middle dressing layer,and cracks are evenly spaced along the length direction of the cutting gauze.The top surface of the middle dressing layer is marked with a second scale.There is an opening at the connection between the lower dressing and the middle dressing,and the bottom surface of the lower dressing is an adhesive layer.This utility model,simple design,good fixing effect,convenient replacement,can avoid catheter slippage and displacement,reduce the occurrence of pressure-related injuries to instruments,and improve the quality of clinical work.It is worth promoting and applying in clinical practice.

OBJECTIVETo explore the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative analgesia of ureteroscopic holmium laser lithotripsy.

METHODSOne hundred and twenty adult patients, American Association of Anesthesiologists (ASA) Class Ⅰ or Ⅱ, scheduled to ureteroscopic holmium laser lithotripsy, were randomly assigned into an observation group and a control group, 60 cases in each one. The patients in the observation group were treated with TEAS for postoperative analgesia. TEAS was implemented at bilateral Shenshu (BL 23) and Yinlingquan (SP 9) at the time of back ward and postoperative 4 h, 8 h, 12 h. TEAS at 7:00, 11:00 and 15:00 at the above acupoints were used on the second and third days; while placebo (twice a day, 100 mg a time) was used. Tramadol hydrochloride tablets for postoperative analgesia were applied in the contnol group, twice a day, 100 mg a time, and electrode sheets without stimulation were put on Shenshu (BL 23) and Yinlingquan (SP 9). When analgesia was insufficient with the score of visual analogue scale (VAS)≥3, the patients were treated with tramadol tablets for remedy analgesia. The VAS score, the concentrations of serotonin (5-HT) and substance P (SP) in 3 mL venous blood at the time of back ward (T), postoperative 4 h (T), 12 h (T), 24 h (T), and 48 h (T) were detected respectively. The total amount of medication for remedy analgesia and the incidence of adverse reactions, such as nausea and vomiting within postoperative 48 h were compared between the two groups.

RESULTSThe VAS scores at T through T were lower than those at T in the two groups (all <0.05). Compared with the control group, the VAS scores at T through T in the observation group were lower (all <0.05). The total dose of remedy analgesic medicine within 48 h after operation in the observation group was lower than that in the control group (<0.05). Compared with the control group, the concentrations of 5-HT at T, T, T and SP at T through T were lower (all <0.05). The numbers of constipation, nausea and vomiting in the observation group were less than those in the control group (both <0.05).

CONCLUSIONTEAS can relieve the pain and reduce the total amount of analgesic medicine, the levels of substance causing pain and the incidence of adverse reactions after ureteroscopic holmium laser lithotripsy.
