# The Swedish Study of Irrigation Fluid Temperature in the Evacuation of Chronic Subdural Hematoma

**Official Title:** The Swedish Study of Irrigation Fluid Temperature in the Evacuation of Chronic Subdural Hematoma - A Multicenter Randomised Controlled Trial

**NCT ID:** [NCT02757235](https://clinicaltrials.gov/study/NCT02757235)

## Key Facts

- **Status:** COMPLETED
- **Phase:** NA
- **Study Type:** INTERVENTIONAL
- **Target Enrollment:** 588
- **Lead Sponsor:** Sahlgrenska University Hospital
- **Collaborators:** Karolinska University Hospital, Uppsala University Hospital
- **Conditions:** Chronic Subdural Hematoma
- **Start Date:** 2016-03
- **Completion Date:** 2020-10-20
- **CT.gov Last Update:** 2022-02-28

## Brief Summary

The study will be a multicenter randomised controlled trial of the use of irrigation fluid of body temperature versus irrigation fluid of room temperature during burr hole evacuation of chronic subdural hematoma.

## Eligibility

- **Minimum age:** 18 Years
- **Sex:** ALL
- **Healthy Volunteers:** No

```
Inclusion Criteria:

* Patients with chronic subdural hematoma requiring burr hole evacuation.
* Patients older than 18 years of age.

Exclusion Criteria:

* Chronic subdural hematoma requiring surgical treatment other than burr hole evacuation.
* Chronic subdural hematoma in a patient with an intracranial arachnoidal cyst.
* Chronic subdural hematoma in a patient with a Cerebro Spinal Fluid-shunt.
* Patients who have undergone intracranial surgery before.
```

## Arms

- **Irrigation fluid of body temperature** (ACTIVE_COMPARATOR) — During burr hole evacuation of the chronic subdural hematoma the irrigation fluid used will be of body temperature (approximately 37 degrees Celsius)
- **Irrigation fluid of room temperature** (ACTIVE_COMPARATOR) — During burr hole evacuation of the chronic subdural hematoma the irrigation fluid used will be of room temperature (approximately 22 degrees Celsius)

## Interventions

- **Irrigation fluid of body temperature** (PROCEDURE) — Irrigation fluid of body temperature will be used during burr hole evacuation of chronic subdural hematoma
- **Irrigation fluid of room temperature** (PROCEDURE) — Irrigation fluid of room temperature will be used during burr hole evacuation of chronic subdural hematoma.

## Primary Outcomes

- **Recurrence rate** _(time frame: 6 months)_ — Recurrences requiring repeat surgery during a 6-month follow up period

## Secondary Outcomes

- **Mortality** _(time frame: 6 months)_
- **Complications related to the surgery** _(time frame: 6 months)_
- **Health related quality of life** _(time frame: 6 months)_
