Abstract

OBJECTIVE

To compare the hemodynamic responses to orotracheal intubation using a Shikani Optical Stylet (SOS) laryngoscope or a Macintosh direct laryngoscope (MDLS).

METHODS

Totally 41 patients with American Society of Anesthesiologists ASA physical status -aged 20-60 years and scheduled for elective surgery under general anesthesia requiring orotracheal intubation, were randomly allocated to either the SOS group (n=21) or MDLS group (n=20). After an intravenous anesthetic induction the orotracheal intubation was performed using a SOS laryngoscope or a MDLS. Blood pressure and heart rate (HR) were recorded before and after anesthetic induction immediately after intubation, and 5 minutes after intubation. Rate pressure product RPP were calculated.

RESULTS

Blood pressures and RPP in both two groups significantly decreased after anesthetic induction (P<0.05) while blood pressures HR, and RPP significantly increased after orotracheal intubation (P<0.05). HR in both groups after intubation were significantly higher than the pre-induction level (P<0.05)and such an increase lasted for 3 min. HR immediately after intubation was also significantly higher in MDLS group than in SOS group (P<0.05); however, such difference was not observed in other time points (P>0.05). In the MDLS group when compared with the occurrence time required for the maximum values of systolic blood pressure (SBP)the occurrence time required for the maximum values of HR after the start of intubation and success of intubation during the observation were significantly delayed (P<0.05). Compared with the MDLS group, the occurrence time required for the maximum values of SBP after the start of intubation and the success of intubation were significantly delayed in the SOS group (P<0.05). The incidences of SBP more than 130% of baseline value and RPP more than 22 000 were not significantly differently(P>0.05). Also, the intubation time was not significantly different (P>0.05).

CONCLUSION

The hemodynamic responses to orotracheal intubation is milder in SOS laryngoscope than in MDLS.
