Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients undergoing Endovascular treatment (EVT) for unruptured cerebrovascular aneurysms were randomized to secure the airway with a laryngeal mask airway (LMA, a supraglottic airway device which is frequently used to secure airway for general anesthesia, and also as an alternative to tracheal tube for difficult airway interventions) or tracheal tube (TT). LMA is placed after the induction of general anesthesia, and removed at the end of the procedure, which means after the surgery and/ or intervention is completed, anesthesia is discontinued and the patient is awaked, the same conditions for TT. Anesthesia was induced with propofol and fentanyl and maintained with remifentanil/propofol-based intravenous anesthesia. Rocuronium ( a nondepolarizing neuromuscular blocker, 0.6 mg/kg intravenously, after the induction of general anesthesia, additional doses were not given) was used in group TT to facilitate tracheal intubation. Hemodynamic parameters were measured before and after airway management and throughout the procedure. After the procedure, recovery times were measured. Respiratory events were recorded.
Intervention code [1] 298902 0
Treatment: Devices
Comparator / control treatment
TT is placed by an anaesthesiologist in the trachea using a laryngoscope ( tracheal intubation) in the TTgroup (control group) . The device remains in place until the end of the anaesthesia. The device is removed after the completion of radiological intervention and anesthesia when the extubation criteria have fulfilled.

Active

Outcomes
Primary outcome [1] 303106 0
Td ( time to discharge) from both groups are compared.
Timepoint [1] 303106 0
Td ( time to discharge) means the duration between the end of anesthesia and to be ready for discharge from angiography unit
Secondary outcome [1] 337896 0
Vital parameters (Heart rate as measured by ECG, Peripheral oxygen saturation as measured by pulseoxymetry are composite secondary outcome.
Timepoint [1] 337896 0
before induction (baseline), before (preintubation) and after tracheal intubation or LMA insertion (postintubation), after extubation or removal of the LMA (postextubation), and at 5-min intervals during the procedure.
Secondary outcome [2] 338216 0
Respiratory events ( gagging, laryngospasm, cough etc) are secondary outcomes. These respiratory events were assessed clinically.
This is a composite outcome.
