Randomized Controlled Trial
Efficacy of fentanyl and/or lidocaine on total antioxidants and total oxidants during craniotomy.
The aim of this study was to investigate the oxidative, hemodynamic, and analgesic effects of local lidocaine infiltration, or intravenous (IV) fentanyl injection, or a combination of lidocaine and IV fentanyl during head fixation in a 3-pin headrest in patients undergoing elective craniotomy. ⋯ The combination of fentanyl and lidocaine before pin fixation is useful in preventing severe hemodynamic response to pain stimuli, such as pin fixation, and in increasing total antioxidant levels in the post-fixational period during craniotomy in adults.
