Objective To develop a scale suitable for assessing work stressors among intensive care unit (ICU) nurses and to examine its reliability and validity. Methods The initial questionnaire of the ICU Nurses' Work Stressors Scale was constructed through literature review, ICU nurse interviews, and Delphi expert consultation. A total of 434 ICU nurses were selected as the validation subjects using the convenient sampling method. Item analysis, exploratory factor analysis, and confirmatory factor analysis were conducted to finalize the version of the ICU Nurses' Work Stressors Scale and evaluate its reliability and validity. Results The ICU Nurses' Work Stressors Scale included six dimensions and 34 items. Exploratory factor analysis extracted six common factors with a cumulative variance contribution rate of 77.8%. The results of confirmatory factor analysis demonstrated good model fit. The scale-level content validity index of the scale was 0.965, with item-level content validity index ranging from 0.850 to 1.000. The overall Cronbach's α coefficient of the questionnaire was 0.958, and the test-retest reliability was 0.986. In a survey of 434 ICU nurses testing with the scale, the total score ranged from 22.0-160.0 (82.6±20.6) points. The scores of each dimension including nursing profession, workload, working environment, patient care, family factors and interpersonal relationship were (14.5±4.2), (21.9±5.8), (7.0±2.1), (14.1±4.2), (6.3±2.5) and (18.8±5.7) points, respectively. Conclusion ICU Nurses' Work Stressors Scale demonstrates good reliability and validity and can serve as an effective tool for evaluating work stress among ICU nurses.

Patients requiring extracorporeal membrane oxygenation (ECMO) often need concurrent continuous renal replacement therapy (CRRT). At present, there are various connection methods between ECMO and CRRT circuits, among which in-series integration is the most common. However, ECMO blood flow and catheter type, pressure changes at the pre-pump, post-pump pre-oxygenator, and post-oxygenator segments frequently result in circuit pressures that exceed the alarm threshold of the device. Excessive negative or positive pressures may compromise blood withdrawal and return within the CRRT circuit, leading to frequent system alarms, interruptions in therapy, filter occlusion, and an increased risk of thrombus formation. To address this issue, the critical care nursing team of Zhongda Hospital Affiliated to Southeast University, developed a novel pressure-regulating clamp for CRRT vascular access in ECMO patient, which has been granted a National Utility Model Patent of China (patent number: ZL 2021 2 1496610.7). The device comprises opposing left and right clamp arms joined at the top by a flexible plastic bridge, with dual internal compression surfaces designed to fit CRRT tubing of various calibers. A locking mechanism and serrated strip at the base enable precise adjustment of the compression distance, thereby modulating the tubing's cross-sectional area. This configuration allows real-time regulation of blood flow and stabilization of pressures at blood withdrawal and return sites within the CRRT circuit. By reducing pressure-related alarms and extending filter life, the device may enhance the safety and efficiency of CRRT delivery during ECMO. It is user-friendly, cost-effective, and well-suited for broad clinical implementation, with the potential to alleviate the overall treatment burden on patients and their families.

Ventriculostomy drainage is one of the commonly used surgical techniques in neurocritical care, which can relieve intracranial hypertension and facilitate postoperative cerebrospinal fluid and intracranial pressure monitoring. By placing a drainage tube in the ventricle, blood and fluid accumulation within the ventricle are drained out of the brain, reducing intracranial pressure and preventing brain tissue damage. Clinically, the speed of ventriculostomy drainage is often controlled by measuring the height difference between the drainage opening and the plane of the ventricle, ensuring the safe and effective reduction of intracranial pressure, facilitating the implementation of clinical management plans, and preventing complications. However, how to easily, safely, and effectively measure the height difference between the drainage opening and the ventricular plane remains a challenge in nursing management. Currently, clinical practice often uses a tape measure to measure the height of the ventriculostomy drainage, a process that is cumbersome and time-consuming and susceptible to human error, leading to inaccurate measurements. However, the challenge of easily, safely, and effectively detecting the height difference between the drainage opening and the ventricular plane remains a difficult problem in nursing management. To address this issue, the medical and nursing staff of the intensive care unit (ICU) at Zhongda Hospital, Southeast University, jointly designed a novel ventriculostomy drainage height measurement device, which has been granted a national utility model patent (patent number: ZL 2022 2 1400920.9). This device can be easily and securely fixed to an infusion stand. Using a level within the horizontal measuring part and a rotational structure, the vertical measuring part of the device is adjusted to be perpendicular to the ground. After opening the limit clip, the horizontal part is manually guided down to the appropriate height. The front end of the horizontal measuring part is then extended towards the patient's head, and after confirming the position, the limit clip is closed. At this point, the horizontal height difference between the drainage opening and the ventricular plane can be accurately measured. When temporarily finishing the height measurement of the drainage tube, the device can be folded and stored by retracting the horizontal measuring part and rotating components. This measuring device has a simple operation process, which can improve the accuracy and reliability of the drainage height measurement, enhance treatment outcomes and patient safety, reduce the workload of nursing staff, and has certain clinical promotion and practical value.

With the continuous advancement and innovation in medical equipment technology, the transition between high-flow oxygen therapy, non-invasive ventilation, and invasive ventilation can be easily achieved by adjusting the ventilation mode of ventilators. During the weaning phase for tracheotomized patients, it is necessary to disconnect the ventilator circuit, change the ventilator mode, and gradually extend the weaning time to achieve complete ventilator liberation. During the weaning process, due to patients' excessive dependence on the ventilator, there may be situations where respiratory endpoints and Y-connectors of the ventilator are reconnected for invasive ventilation. However, during the weaning process, the Y-connector and expiratory end connectors are exposed to the air, which cannot ensure the tightness of the ventilator circuit, easily increasing the probability of ventilator circuit contamination and subsequently the risk of ventilator-associated pneumonia (VAP). To overcome these issues, the research team of department of critical care medicine of Zhongda Hospital Southeast University has designed a ventilator circuit interface protective device for weaning and has obtained a National Utility Model Patent of China (ZL 2023 2 1453385.8). The main body of the protective device is a Y-connector plug, consisting of multiple components, including a sealing piece, a protective cover, a sealing plug, an interface 1 (connects with the patient's tracheal tube), an interface 2 (connects with the respiratory branch of the ventilator), and an interface 3 (connects with the expiratory branch of the ventilator), featuring a unique design and easy operation. During the patient's weaning training process, the interface 1 and interface 2 is disconnected from the patient's tracheal tube and respiratory branch, respectively. The interface 1 is plugged with a stopper, and the interface 2 is covered with a protective cover to ensure the tightness of the expiratory branch and Y-connector of the ventilator. During the period when the patient is using the ventilator, the protective cover and plug are removed, and connecting them together ensures the tightness of the device itself, reducing the incidence of VAP caused by ventilator circuit contamination, avoiding nosocomial infections, and shortening the prolonged use of invasive ventilation, increased complication rate, extended hospital stay, and increased medical cost associated with weaning.
