Abstract

The hemodynamic response to the insertion of the laryngeal mask airway (LM) following induction with propofol 2 mg ·kg-1 was assessed and compared in normotensive (Normal), hypertensive (HT) and chronic renal failure (CRF) patients (n=23 in each group). Before induction, in HT and CRF groups blood pressure and rate pressure products (RPP) were higher than in Normal group (P< 0.05). Although blood pressure and RPP were decreased in every patient by induction with propofol, no patients needed vasopressor drugs. The decreases of blood pressure and RPP were larger in HT and CRF groups than in Normal group (P<0.05). There were no differences between groups in heart rate and rate of successful LM insertion. We concluded that LM insertion with propofol 2 mg ·kg-1 was an effective induction method preventing the adverse circulatory responses in normotensive, hypertensive and chronic renal failure patients.
