Study Description

Brief Summary:

Sedation vs Intubation for Endovascular Stroke TreAtment Trial (SIESTA) is a prospective, randomised controlled, monocentric, two-armed, comparative trial. Patients are randomized 1 : 1 to either non-intubated state or to intubated state for endovascular stroke treatment. Otherwise, no principal differences in intensive care treatment are intended, and standard operating procedures are applied to ensure uniform management decisions in fields such as ventilation, sedation, cardio-vascular and cerebral monitoring and management.

Condition or disease	Intervention/treatment	Phase
Acute Ischemic Stroke	Procedure: Endovascular recanalisation	Not Applicable

Detailed Description:

Early recanalization is an important, if not the most important, factor concerning reconstitution of patients´ health in ischaemic stroke. This is the reason why patients with extended stroke are increasingly subjected to an endovascular stroke therapy (EST).

Matter of ongoing debate is how to sedate these patients during intervention. Some clinicians prefer an intubation due to a reduction of patients´movements and therefore potentially lowering complication rates (injury by catheter, aspiration e.g.).

On the other hand retrospective investigations hypothesize that general anaesthesia is associated with peri-interventional hypotension followed by poorer clinical outcome.

The best anaesthaesiologic management in endovascular stroke therapy to this point of time is not known. The investigators therefore designed this study comparing intubated state with general anaesthesia vs. non-intubated state with conscious sedation during EST, focusing on patients´ outcome.

Arms and Interventions

Arm	Intervention/treatment
Active Comparator: Intubation Intubation and invasive mechanical ventilation + endovascular recanalisation	Procedure: Endovascular recanalisation Endovascular recanalisation by mechanical thrombectomy with e.g. stent retriever device, possibly following intravenous thrombolysis within a "bridging concept"
Experimental: No Intubation Conscious sedation and non-invasive ventilatory support + endovascular recanalisation	Procedure: Endovascular recanalisation Endovascular recanalisation by mechanical thrombectomy with e.g. stent retriever device, possibly following intravenous thrombolysis within a "bridging concept"

Outcome Measures

Primary Outcome Measures :

National Institutes of Health Stroke Scale (NIHSS) after 24 hours [ Time Frame: 24 hours ]
Neurological improvement of NIHSS 24 hours after intervention

Secondary Outcome Measures :

Outcome after 3 month using the modified Rankin Scale (mRS) [ Time Frame: 3 month ]
Assessing the neurological outcome after 3 months with the mRS.
Inpatient-mortality [ Time Frame: Mortality-rate until timepoint of discharge, an expected average of 3 weeks. ]
Mortality-rate within the first 3 months after intervention. [ Time Frame: First 3 months after intervention ]

Other Outcome Measures:

Duration of hospital stay [ Time Frame: Participants will be followed until timepoint of discharge, an expected average of 3 weeks. ]
Periinterventional complications [ Time Frame: Evaluation of Adverse Events as a Measure of Safety and Tolerability until timepoint of discharge, an expected average of 3 weeks. ]
Achieved recanalisation grade [ Time Frame: Duration of intervention with an expected average of 2 hours ]
Recanalisation status is classified according to the Thrombolysis in Cerebral Infarction classification (TICI).
