Brief summary

In this study, we aimed to investigate the effect of metoprolol on the frequency and severity of pain caused by rocuronium injection in patients who started to use and were currently using oral metoprolol for any reason such as ischemic heart disease, hypertension, and arrhythmias. All patients were informed about the objectives of the study and gave informed written consent. The study was conducted in accordance with the relevant ethical principles of the Declaration of Helsinki. This study was planned as a prospective, placebo-controlled, cohort study were evaluated in four groups. Group M: patients currently using metoprolol and who did not receive lidocaine before the application of rocuronium. Group ML: patients currently using metoprolol and who received lidocaine before rocuronium application. Group L: patients currently not using metoprolol and received lidocaine before rocuronium application. Group C: patients currently not using metoprolol and who did not receive lidocaine before rocuronium application. 200 patients with 50 being in each of four groups were included in the study.

Detailed description

Following the induction of general anesthesia with thiopental sodium, a researcher blind to the groups observed the pain during rocuronium injection based on the following scale: 1: no reaction, 2: movement only in the ankle, 3: movement or withdrawal only in the arm (shoulder and ankle), 4: diffuse reaction (movement or withdrawal in more than one extremity, coughing and holding breath).Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), and SpO2 values were recorded before rocuronium administration, 1 and 3 minutes after rocuronium induction, and after intubation. Anesthesia maintenance was performed according to the discretion of the anesthetist. We checked the injection site regarding edema, rash, and thrombophlebitis after the first 24 hours of the operation.
