Abstract
This study was carried out to evaluate the effects of fentanyl on cardiovascular and catecholamine responses during rapid sequence induction (RSI) in hypertensive patients. Twenty-eight patients were allocated into one of 3 groups: group 1 (n=7) consisted of normotensive patients receiving no fentanyl, group 2 (n=10) consisted of normotensive patients receiving fentanyl, and group 3 (n=11) consisted of hypertensive patients receiving fentanyl. RSI was performed with thiamylal (4mg·kg−1) and succinylcholine (2mg·kg−1) for all groups. In groups 2 and 3, fentanyl (4 μg·kg−1) was given prior to induction. Measurements including systolic arterial pressure (SAP) and heart rate (HR) were made at preinduction (T1), preintubation (T2), 1 min after intubation (T3), and 3 min after intubation (T4). Simultaneously, plasma concentrations of epinephrine (E) and norepinephrine (NE) were measured at T1 and T3. Group 1 showed significant increases in SAP, HR, and NE at T3 as compared to T1. Group 2 showed a significant increase in HR at T3 but not in SAP or catecholamines. Group 3 showed no increase in SAP, HR, or catecholamines throughout the time course. The results suggest that fentanyl is useful to suppress sympathoadrenal and cardiovascular responses to RSI in hypertensive patients as well as normotensive patients.
