Abstract:
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.
