Using Ambu Aura-i Laryngeal Mask Airway in Cranial Surgery

The Effect of Using Ambu Aura-i Laryngeal Mask Airway Versus Endotracheal Tube on Emergence Hypertension in Supratentorial Cranial Surgery: A Randomized Controlled Study

the investigators hypothesize that Ambu aura-i LMA can be used safely in patients undergoing craniotomies and are effective in reducing the incidence of emergence hypertension.

In this study the investigators want to assess the safety of using SGA devices in cranial surgery and comparing the effect of these devices with ETT regarding hemodynamics stability throughout the procedure and intracranial tension.

Inclusion Criteria:

1. Study will be conducted on patients undergoing craniotomies under general anaesthesia in supine position.
2. Aged 18 to 60 years.
3. ASA 1 or 2.
4. GCS ≥ 13.

Exclusion Criteria:

1. Patients who are known hypertensive, history of cardiac diseases or chest diseases
2. Patients with risk of aspiration (Obesity with BMI ≥ 40, hiatal hernia, esophageal cancer and previous esophageal surgery).
3. Risk of difficult intubation
4. Extensive intracranial tumours that may affect recovery of patients.
