Low Intracranial Pressure Treatment Strategies for Chronic Subdural Hematoma Patients (CSDH-LP)

November 6, 2020 updated by: Xuehai Wu, Huashan Hospital

Effectiveness and Safety of Low Intracranial Pressure Treatment Strategies for Patients With Chronic Subdural Hematoma - A Randomized, Controlled, Multi-center Clinical Study

The proportion of the elderly population is increasing rapidly. Chronic subdural hematoma has become the most common cause of surgery in neurosurgery for elderly patients. The standard treatment for cSDH is mostly surgery. Clinically, we often encounter elderly patients with certain underlying diseases or organ dysfunction, especially preexisting cardiovascular disease or medication history like anticoagulant or antiplatelet drugs, resulting in poor surgical tolerance, high risk during anesthesia and hematoma recurrence. At present, the mechanism of cSDH is not completely clear. Our previous observational studies had shown significant correlation between cSDH and intracranial hypotension. So we would like to conduct a randomized, controlled, multi-center clinical study to explore the effectiveness and safety of low intracranial pressure treatment strategies for patients with chronic subdural hematoma.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
160

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (ADULT, OLDER_ADULT, CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • patients above 14 yrs with chronic subdural hematoma confirmed by cranial imaging;
  • patients with MGS-GCS score ≤1 point, showing no signs of neurological deficits caused by CSDH or characteristics of high intracranial pressure;
  • patients with MGS-GCS score ≥1 point, but with medication history of anticoagulant or antiplatelet drugs, coagulation dysfunction so that they are unsuitable or intolerant of surgery although they are in stable condition;
  • patients who are unwilling to operate when they have no life-threatening brain herniation or no indications for emergency surgery, which confirmed by two neurosurgeons

Exclusion Criteria:

  • women pregnant or in lactation
  • those who are allergic to atorvastatin, hypoxamethasone;
  • patients with brain herniation or altered mental status;
  • patients with primary diseases like tumors, hemorrhagic diseases or some other critically serious conditions( eg.multiple organ failure);
  • patients with uncontrollable diabetes and heart failure
  • patients with preexisting chronic abdominal diseases (such as inflammatory bowel disease) or lung tumors or digestive system neoplasm
  • Patients with abnormal liver function
  • patients had taken atorvastatin or dexamethasone, ACEI in the past one week
  • other conditions not eligible to enroll the trial confirmed by two individual doctor

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
subdural hematoma volume
Time Frame: three months
difference of hematoma volume in subdura between two groups
three months
Markwalder scale
Time Frame: three months
difference of Markwalder scale between two groups;The Markwalder Scale is designed to measure the chronic subdural hematoma scale. This scale is categorized into four grade. Grade 0 denots the patient neurologically normal, whereas grade 4, the highest grade, denotes the worst neuological assessment.
three months
Modified Rankin Scale
Time Frame: three months
difference of Modified Rankin Scale between two groups; The modified Rankin Scale is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a neurological disability. The scale runs from 0-6, running from perfect health without symptoms to death.
three months
Extended Glasgow Outcome score
Time Frame: three months
difference of Extended Glasgow Outcome score between two groups; This score is used to measure the outcome after neurological disease. It defines 5 categories of possible outcomes after a brain injury, which is from good recovery(5) to death(1).
