Abstract :Aim: Endotracheal intubation, a critical procedure in anaesthesia, can induce significant hemodynamic fluctuations, posing risks, especially to patients with cardiovascular concerns. This study compares the effects of dexmedetomidine and fentanyl, two agents commonly used to mitigate these responses, on endotracheal intubation conditions and associated hemodynamic changes. Material and Method: Conducted at tertiary care training and research hospital, this study involved 60 patients aged 40-60, all classified American Society of Anesthesiologists (ASA) I-II, undergoing elective upper and lower extremity surgeries. Excluding patients with contraindicating conditions, the subjects were divided into two groups to receive either dexmedetomidine or fentanyl, along with propofol and vecuronium, for induction. Hemodynamic parameters were continuously monitored, and intubation conditions were assessed using the Cooper scoring system. Results: The study found that both dexmedetomidine and fentanyl effectively stabilised hemodynamic parameters during intubation. However, the fentanyl group displayed significantly higher total scores on the Cooper intubation conditions scale, indicating more favourable conditions for endotracheal intubation in terms of ease and patient comfort. Conclusion: While both dexmedetomidine and fentanyl are effective in maintaining hemodynamic stability during endotracheal intubation, fentanyl demonstrates a slight advantage in optimising intubation conditions. This distinction offers valuable insight for anesthesiologists in tailoring anaesthetic strategies and balancing patient safety with procedural efficiency in surgical settings.
