Abstract

 Aims: ENDOTRACHEAL INTUBATION is an invasive technique which is associated with severe cardiovascular complications. This study aimed to compare the effects of LIDOCAINE 10% spray on the laryngoscope blade with intravenous LIDOCAINE on cardiovascular responses to laryngoscopy and intubation in elective surgical patients.Materials & Methods: In this clinical trial that is performed in 2013, 90 candidates of elective surgery in Gonobad City, Iran hospitals were randomly divided to three groups; control (no drugs were used), intravenous LIDOCAINE (three minutes before laryngoscopy) and LIDOCAINE 10% (just before laryngoscopy). Heart rate and systolic blood pressure, diastolic blood pressure and mean arterial blood pressure were recorded immediately before, immediately after, and 1, 3 and 5min after laryngoscopy. Data were analyzed using SPSS 20 by repeated ANOVA and Tukey post hoc tests.Findings: There were significant differences in systolic, diastolic and mean arterial blood pressure between control group and each intravenous LIDOCAINE and LIDOCAINE 10% groups after laryngoscopy (p<0.001). There was no significant difference in any of the three variables between intravenous and spray groups. No significant difference was found between the three groups in heart rate (p=0.16).Conclusion: Compared with intravenous LIDOCAINE administration, LIDOCAINE 10% spray on the laryngoscope blade lead to better stability in blood pressure after laryngoscopy, but has no effect on the heart rate.
