Investigating the effects of fentanyl and nitroglycerin on hemodynamic changes during laryngoscopy; A Randomized Trial

Laryngoscopy is the required procedures in general anesthesia that can cause cardiovascular disorders for the patient. Various pharmacological methods are used to reduce unwanted laryngoscopy responses. The present study aimed to compare the effects of fentanyl and nitroglycerin spray on hemodynamic responses during laryngoscopy

喉镜检查是全身麻醉过程中不可或缺的程序，该程序可能导致患者出现心血管疾病。为了减轻不必要的喉镜检查反应，研究者们采用了多种药理学方法。本研究旨在比较芬太尼喷雾和硝酸甘油喷雾在喉镜检查期间对患者血流动力学反应的影响。
