- Brno University Hospital
- Brief Summary
The purpose of the study is to assess feasibility of future large randomised controled study aimed on assessment of effect of goal-directed therapy on incidence of complications in neurosurgery compared to standard care.
- Detailed Description
Patients undergoing neurosurgical operations are at risk of inadequate intravascular volume for several reasons. The appropriate fluid management in neurosurgery is a challenge. Goal-directed therapy has been shown to improve the outcome of patients undergoing major surgery. Current knowledge regarding effect of fluid management on patient-orientated outcomes in neurosurgery is limited.
This study is designed as a pilot study with two parallel groups. Patients scheduled to planned brain surgery at the University Hospital Brno will be screened whether they meet the inclusion criteria. After obtaining informed consent, the patient will be randomized to one of the study arms.
In one arm (STANDARD) standard monitoring of vital signs will be introduced. During the operation, perioperative fluid therapy and administration of vasoactive agents will depend entirely at the discretion of the attending anaesthetist. Postoperative therapy will be fully controlled and will depend on the decision of the attending physician. In the second arm (GDT), a non-invasive hemodynamic monitor STARLINK™SV will be introduced in addition to standard monitoring. In this arm, basal infusion with crystalloid balanced solution will be initiated. Additional boluses of fluids will be administered based on haemodynamic monitoring. The primary outcome of the study is a proportion of patients with serious adverse event (SAE). Incidence of SAEs will be compared between study groups. SAE will be defined as unsatisfactory brain tissue relaxation at the end of operation and any intervention for brain oedema postoperatively.
The secondary outcome is to compare proportion of patients with postoperative complications in both groups and length of ICU and hospital stay.
This study will enroll 34 patients in total, 17 in each group. After completion of enrolment of patients the statistical analysis will be performed.

Group Intervention Description GDT Goal-Directed Therapy A non-invasive hemodynamic monitor STARLINK™SV will be used in addition to standard monitoring. STANDARD STANDARD In this arm standard monitoring of vital signs will be used during operation.
- Primary Outcome Measures
Name Time Method Completeness of Case Report Forms through study completion, an average of 6 months Proportion of enrolled patients with completed Case Report Form.
Serious Adverse Events 2 24 hours postoperatively Assessment of number of patients with serious adverse event (SAE). SAE is defined as any intervention indicated for treatment of brain edema 24 hours after surgery.
Recruitment rate through study completion, an average of 6 months Proportion of eligible patients who consent to participate in the study.
Serious Adverse Events 1 During the Surgery Assessment of number of patients with serious adverse event (SAE). SAE is defined as unsatisfactory brain tissue relaxation at the end of surgery assessed by neurosurgeon. Level 3 or 4 of brain tissue relaxation will be considered as unsatisfactory (level 1 - completely relaxed, level 2 - satisfactorily relaxed, level 3 - firm, level 4 - bulging).
- Secondary Outcome Measures
Name Time Method Complications through study completion, an average of 6 months Number of patients with pre-defined postoperative complication.
