Abstract EN
Introduction Laryngoscopy as well as tracheal intubation causes changes in the hemodynamics of the patient owing to stress response.
C-MAC videolaryngoscope (VL) is a relatively recent development that improves the success of tracheal intubation.
Aim The aim of this study was to compare and evaluate the effects of dexmedetomidine for attenuation of hemodynamic responses during laryngoscopy using Macintosh laryngoscope versus C-MAC laryngoscope.
Patients and methods A total of 60 patients, ASA II, 18–60 years old, scheduled for different surgeries under general anesthesia with BMI up to 40 kg/m2 were included in the study.
Patients were divided into two groups (30 patients each) and were appropriately positioned, and intubation was done.
Hemodynamic stress response to intubation was recorded, and plasma epinephrine level was estimated at baseline and at 1 and 5 min after intubation.
Success rate, duration, attempts of intubation, and SpO2% were assessed.
Results Plasma epinephrine level (ng/ml) at baseline and at 1 and 5 min after intubation showed no statistically significant difference in both groups, but there were highly significant differences at 1 and 5 min after intubation compared with baseline values (P<0.0001 and <0.0007, respectively) in each group.
Intubation time was longer in ML (17±4.47 s) compared within VL (12±3.4 s).
There were no significant differences between both groups after intubation regarding hemodynamic changes, SpO2, or EtCO2.
Conclusion The stress response in both laryngoscopic techniques appears to be the same as detected by the nonsignificant difference in plasma epinephrine levels and hemodynamic changes in both groups, so 1 μg/kg dexmedetomidine is not enough to obtund the stress response completely.
C-MAC VL is an efficient and suitable intubating device and provides excellent visualization of laryngeal structures in shorter time with less intubation attempts than Macintosh (Techron Surgical, Sialkot, P, Pakistan) laryngoscopy.
