Aim: To comparatively analyze and determine the effects of esmolol, lidocaine, and nitroglycerin on hemodynamic response to extubation, extubation quality and postoperative pain, based on the placebo effect.
Material and Methods: Our study design covers a prospective, randomized clinical trial in 120 patients who underwent intubation. Random division was applied onto the patients to obtain 4 groups: Esmolol, Lidocaine, Nitroglycerin, and Saline. In preparation for extubation; when the train-of-four (TOF) value reached 75% (basaline), study drugs were administered. When TOF ≥90%, the patients were extubated. Heart rate (HR) and mean blood pressure (MBP) records were taken prior to induction, when TOF 75% and 90, 1st, 3rd, and 5th. minutes after drugs were administered and extubation. Extubation time, quality, and postoperative pain values were recorded.
Results: When compared to the Placebo group based on post extubation measurements, the Esmolol group had no significant difference for MBP at any time but lower HR as recorded at the fifth minute (P:0.012). For both indicators, it significantly decreased according to pre- and post excubation records, with the Nitroglycerin group (P
