D Ling, Ji Dr

Abstract

UNLABELLED: The purpose of this study was to observe the effect of lidocaine on cardiovascular responses to stomach-tube intubation. 80 patients (ASA I-II) were randomly divided into two groups: study group with 2% lidocaine 5 ml throat surface anesthesia (n = 40) and control group without lidocaine (n = 40). Hemodynamic variables including systolic blood pressure (SBp), heart rate (HR), and rate-pressure product (RPP) were measured before, immediately, 1 min, 3 min, ore stable than that in control group (P < 0.05 or P < 0.01). CONCLUSION: 2% lidocaine can effectively prevent cardiovascular responses to the intubation.
