Background: Emergence hypertension is one of the complications during the awakening from anaesthesia. Limited studies reported utilizing Laryngeal Mask Airway [LMA] in craniotomy surgeries, thus we aimed to assess the incidence of emergence hypertension and hemodynamic stability when using Ambu aura-i LMA compared to the endotracheal tube [ETT] for ventilating craniotomy patients undergoing supratentorial brain tumor surgeries.
Methods: One hundred and twenty patients participated in this randomized controlled study and were assigned to two groups, the LMA group in which the Ambu aura i LMA was used in airway management for general anaesthesia, and the ETT group in which the endotracheal tube was utilized. The incidence of emergence hypertension, hypertension with airway device insertion, and postoperative complications were recorded.
Results: The LMA group showed a lower incidence of emergence hypertension when compared to the ETT group [48.3% versus 81.7% respectively; P ˂ 0.05]. LMA was associated with a lower HR and fewer patients required vasoactive agents during emergence. Moreover, the LMA group expressed a decreased incidence of hypertension with insertion compared to the ETT group [1.7% versus 18.3% respectively; P ˂ 0.05], besides a lower incidence of postoperative cough, sore throat, and hoarseness.
Conclusion: Using Ambu Aura-i LMA in craniotomy surgeries showed a lower incidence of emergence hypertension, more hemodynamic stability during induction, and emergence of anaesthesia, with a decreased incidence of postoperative complications compared to ETT.
