Abstract:
From May 2012 to May 2013, 60 chronic male smokers received an intravenous infusion of dexmedetomidine 1 μg/kg (Group D, n=30) or an equal volume of normal saline (Group C, n=30) before anesthesia induction.At time of dexmedetomidine or normal saline dosing , after induction of anesthesia, 1 and 3 min after intubation, the heart rates and rate-pressure products were significantly lower in Group D than Group C ( P<0.05 ).Thus the dosing of dexmedetomidine before anesthesia induction could suppress the cardiovascular responses of endotracheal intubation in chronic smokers and avoid increasing myocardial oxygen consumption so as to protect heart functions.
