Primary Outcome Measures:
  • Blood pressure [ Time Frame: 3 min ]
    Non invasive blood pressure every min for 3 min

Secondary Outcome Measures:
  • Post operative sore throat [ Time Frame: 3 days ]
    Questionnaire for Post operative sore throat

Estimated Enrollment: 70
Study Start Date: January 2013
Estimated Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Lidocaine
Inhalation of lidocaine before intubation
Drug: Lidocaine inhalation
Lidocaine inhalation before intubation
Placebo Comparator: Control
Normal saline inhalation before intubation
Drug: Placebo

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.
