Abstract

BACKGROUND: This study was performed to evaluate the hemodynamic changes of insertion of a laryngeal mask airway ProSealTM (PLMATM) or tracheal intubation in hypertensive patients.
METHODS
Twenty hypertensive patients, aged between 41 to 73 yrs, undergoing an elective surgery, were studied. All patients were allocated randomly to have their surgery performed with endotracheal intubation (Group ET, n = 10) or PLMA(TM) (Group PLMA, n = 10) and were studied for cardiovascular responses related to intubation or PLMA(TM) insertion. Anesthesia was induced with thiopental sodium and vecuronium intravenously. The lungs were then ventilated manually through a facemask with 1.0% enflurane in oxygen and maximal changes (%) in systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP) and heart rate (HR) were measured after tracheal intubation or PLMA(TM) insertion after anesthetic induction.
RESULTS
The maximal changes (%) in SBP, DBP, MBP and HR were less in Group PLMA than in Group ET during the observation period (SBP: 7.2 +/- 6.8 vs 55.7 +/- 5.7, DBP: 7.3 +/- 6.3 vs 47.5 +/- 8.3, MBP: 7.9 +/- 6.9 vs 50.5 +/- 5.7, HR: 10.8 +/- 7.2 vs 48.2 +/- 6.1, P < 0.05).
CONCLUSIONS
PLMA(TM) insertion elicited less hemodynamic change than tracheal intubation in hypertensive patients.
