Abstract: 

Introduction: Hemodynamic changes are of the intratracheal intubation complications, which anesthesiologists always tend to avoid. In this study, we evaluated hemodynamic changes like HR, BP, post thracheal intubation using Macintosh laryngoscope versus fiberoptic bronchoscope.

Methods: Ninety-seven ASA class I, II elective surgery candidates were selected and were divided into two groups of 45 and 52 patients, randomly. Those with excessive obesity, difficult intubations, and systemic disorders like hypertension, diabetes, thyroid disorders and Cesarean candidates were excluded. After using standard monitoring, premeditation and anesthesia induction were done with same methods for all the patients. Intubations period was recorded in seconds. Hemo-dynamic changes like HR, BP, SaO2 in 4 different times were recorded either. All the information was analyzed using SPSS program and using t-test and Chi-square test.

Results: There was no significant difference between the operational period and age and sex of subjects. Intubational period in fiberoptic group was significantly longer than the Macintosh group. There were significant differences between the two groups in mean SaO2 and mean arterial pressure 30 seconds after intubations. Heart rate after intubations did not show any significant different between the groups.

Conclusion: Considering all the above results, it seems that intubations using fiberoptic bronchoscopes causes more hemodynamic changes compared with Macintosh laryngoscope. Considering the proportional equal conditions like anesthesia type and method, premedication, age, sex, etc, this difference is likely arised due to the effects of fiberoptic bronchoscope on lower part of trachea.
