Intubating conditions with propofol under muscle relaxation with vecuronium bromide. A time-related comparison with thiopental.
In the present study a comparison has been made between intubating condition obtainable after anesthesia induction with Thiopental or Propofol, using Vecuronium Bromide to achieve muscle relaxation. Data were collected about hemodynamic parameters, vocal cords position, coughing or bucking, and involuntary movements. Three-hundred patients, males and females, ASA classes I and II, not premedicated, were included in the study; they all had to undergo surgery requiring tracheal intubation. The patients were divided in six different groups, and in each of them intubation was performed at different times from injection of inducing agents (2-2, 30-3-4-5-6 minutes). Overall results show a lack of satisfying intubating conditions on the extreme of selected times (2 and 5-6 minutes), with no significant difference between Thiopental and Propofol, except for a minimal unlike behaviour in hemodynamics. Therefore, on the basis of our data, as far as intubating conditions are considered, we can conclude that there is no reason to prefer one of the two inducing agents.
