Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Surgery - Blood pressure management of Systolic Blood Pressure to maintain target range +/- 10 mmHg

Active Comparator: Augmented - Systolic Blood Pressure (SBP) at 170mmHg +/- 10 mmHg - Techniques used to target SBP will not be controlled for and will be at the discretion of the procedural anaesthetist to manage blood pressure, this can include vasopressors, intravenous fluids, titration of anaesthetic maintenance drugs and use of other vasoactive drugs.

Active Comparator: Standard - Systolic Blood Pressure (SBP) at 140mmHg +/- 10 mmHg - Techniques used to target SBP will not be controlled for and will be at the discretion of the procedural anaesthetist to manage blood pressure, this can include vasopressors, intravenous fluids, titration of anaesthetic maintenance drugs and use of other vasoactive drugs.

Summary
Brief summary
Stroke is the third most common cause of death in New Zealand and is one of the leading
causes of long-term disability at all ages. A life-saving clot retrieval procedure can save
lives and prevent disability of patients with ischaemic stroke who get to hospital in time.
In New Zealand, 90% of clot retrieval procedures are performed under general anaesthesia.
Many anaesthetic drugs can affect blood pressure (BP) and blood flow within the brain.
Increasing BP during the procedure could provide additional benefits in this devastating
disease. A large trial is needed to investigate BP management during clot retrieval.
