Brief Summary:
We investigate the potential benefits of ultrasound-driven lidocaine inhalation immediately before induction.

Condition or disease Intervention/treatment Phase
Sore Throat Drug: Lidocaine inhalation Drug: Placebo Not Applicable

Detailed Description:
Sudden increases in blood pressure and heart rate after tracheal intubation and post-operative sore throat are two common undesirable side effects of general anesthesia and might lead to patients' morbidity or dissatisfaction. We investigated the possibility to attenuate both side effects with one single method, i.e. ultrasound-driven lidocaine inhalation immediately before induction.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 70 participants
