Attenuation of the hemodynamic response to laryngoscopy and tracheal intubation: A randomized controlled trial

Abstract

Background: Fentanyl and lidocaine are two drugs that are often suggested to lower the reaction of the blood flow to laryngoscopy and endotracheal intubation. Aims and Objectives: The main goal of our study is to find out how the heart and blood vessels react when laryngoscopy and intubation are used. A comparison was made between fentanyl 2 mcg/kg and fentanyl 2 mcg/kg plus 15 mg of paracetamol per kg of body weight. The goal was to find the best and safest ways for these options to reduce stress during laryngoscopy and intubation. Materials and Methods: The anesthesiology department and the general surgery department at the medical college and hospital that is connected to it worked together on the study. The study included a total of 120 patients, covering a wide age range from 20 to 70 years, and including both males and females. The patients had physical statuses I and II, indicating their overall health. In Group A, patients were given a pre-medication of 0.02 mg/kg of glycopyrrolate and then 2 mg/kg of fentanyl through an intravenous (IV) 90 s before they were intubated. Fentanyl at a dose of 2 mcg/kg was given to patients in Group B 90 s before they were intubated. A dose of 15 mg/kg of paracetamol was also given 10 min before the operation. As a starting point, the medical team wrote down the patient’s heart rate (HR), systolic and diastolic blood pressures, and mean artery pressure before they started intubation. Results: Large rise in HR was seen in Group A, while Group B’s HR stayed close to the baseline. There was a clear rise in mean blood pressure in both groups after intubation. Group A, on the other hand, saw a rise that was clear and lasted for 6 min, while Group B did not. When compared to IV fentanyl alone, IV fentanyl and paracetamol work better at lowering the changes in blood flow that happen during laryngoscopy and airway intubation. Conclusion: This finding highlights the potential benefits of combining these two medications for improved patient outcomes. Endotracheal intubation, fentanyl, paracetamol, and laryngoscopy are all important medical terms that are commonly used in health-care settings. These procedures and medications play a crucial role in various medical interventions and treatments. Understanding the significance and proper usage of these terms is essential for health-care professionals to provide effective care to their patients.
