PARVEZ, Gazi et al. Attenuation of the Pressor Response to Laryngoscopy and Tracheal Intubation with Intravenous Diltiazem and Esmolol Intravenous in Controlled Hypertensive Surgical Patients. Rev. colomb. anestesiol. [online]. 2010, vol.38, n.4, pp.457-469. ISSN 0120-3347.
Introduction. Tachycardia and hypertension are well documented sequels of laryngoscopy and endotracheal intubation which is transient, highly variable and is generally well tolerated in healthy patients. In hypertensive patients, cardiovascular response to laryngoscopy and intubation is exaggerated. The aim of this study intended to find a better alternative by comparision amongst diltiazem and esmolol to attenuate the pressor response to laryngoscopy and intubation in Kasmiri Population. Materials & Methods. Randomized placebo controlled double blind study. One hundred fifty hypertensive patients of both sexes (ASA II), controlled on antihypertensive drugs, between age hinrange of 40-60 years scheduled for routine surgical procedures were divided into 3 groups Group A (10 ml of 5 % Dextrose), Group B (Diltiazem 0.2 mg/Kg) and Group C (Esmolol 1.5 mg/Kg). Baseline parameters, i.e. heart rate, systolic blood pressure, diastolic blood pressure, mean arterial blood pressure and rate pressure product were noted at baseline level, at 1 min., 3min. and 5min after tracheal intubation. Results. Both Esmolol and Diltiazem showed statistically significant attenuation of rise in systolic blood pressure, diastolic blood pressure, mean arterial blood pressure and rate pressure product when compared to control. However Diltiazem failed to attenuate rise in heart rate. Conclusions. We conclude that Esmolol is a very effective agent in attenuating the pressor response to laryngoscopy and intubation in controlled hypertensive patients.
