Recruiting

• Conditions: Chronic Subdural Hematoma; Recurrence

• Registration Number: NCT06401772
• Lead Sponsor: Huashan Hospital

Brief Summary

This study aims to investigate the effectiveness and safety of body posture to improve intracranial pressure in preventing postoperative recurrence for chronic subdural hematoma

Detailed Description

This study is a multicenter prospective randomized clinical trial with open-label treatment and blinded outcome assessment to evaluate the effects of body posture on hematoma recurrence. Patients will be assigned in a 1:1 ratio to body posture group(upper body lay flat, lower body elevate 30° or 20-30cm, head turn to affected side) or control group(supine position) randomly. After operation, patients will be required to keep respective body posture at sleep time for 3 months. Instead of body posture, patients will receive routine treatment.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: PARALLEL

Primary Outcome Measures

Name	Time	Method
subdural hematoma recurrence rate	within 90±10 days post-surgery	Recurrence is defined as maximum thickness of subdural hematoma more than 10mm, and patients have subdural hematoma related symptoms without head injury.

Secondary Outcome Measures

Name	Time	Method
change in EQ-5D-5L score compared to baseline	90days and 1year post-surgery	The 5-level EQ-5D version (EQ-5D-5L) is a standardised measure of health status
differences between two group in comorbidities	90days post-surgery	comparison of comorbidities rate of two group
subdural hematoma recurrence rate	1year post-surgery	comparison of recurrence rate of two group
change in modified Rankin Scale(mRS) compared to baseline	90days and 1year post-surgery	The mRS is a clinician-reported measure of global disability,ranging from 0 to 6, with higher scores indicating more severe disability
differences between two group in complications	90day post-surgery	comparison of complications rate of two group
differences between two group in recurrence time	within 90days and 1year post-surgery	comparison of recurrence time of two group
all cause recurrence rate	90days and 1year post-surgery	comparison of recurrence rate of two group caused by whatever the reasons
