History of Changes
  Purpose

Hypnosis may reduce patient anxiety. The main goal of this study is to determine in what extent, hypnosis decreases propofol requirement to induce induction of general anesthesia.

A particular aspect of this study is that induction is provided by a closed-loop system which delivers propofol according to bispectral index.

Further study details as provided by Hopital Foch:

Primary Outcome Measures:
  • Administered dose of propofol required to obtain the induction of anesthesia (bispectral index <60 for at least 30 seconds) [ Time Frame: one hour ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • calculated target plasma concentration corresponding to induction of anesthesia (bispectral index <60 for at least 30 seconds) [ Time Frame: one hour ] [ Designated as safety issue: No ]
  • pain of injection [ Time Frame: one hour ] [ Designated as safety issue: No ]

    Pain is assessed by two criteria:

    • withdrawal of the arm perfused (no = 0; withdrawal = 1; violent withdrawal = 2),
    • spontaneous expression (no = 0; frown = 1 grin = 2)

  • Hemodynamic consequences of induction of anesthesia [ Time Frame: one hour ] [ Designated as safety issue: No ]
    Heart rate and blood pressure are measured just before induction of anesthesia and once it realized.

  • characteristics of the hypnotic procedure [ Time Frame: one hour ] [ Designated as safety issue: No ]
    • For speed: focus obtained in a very fast (1), fast (2), medium (3), delayed (4), impossible to obtain (5).
    • For quality: very deep (1), deep (2), medium (3), superficial (4), not obtained (5)

  • Patient assessment of the induction of anesthesia [ Time Frame: one hour ] [ Designated as safety issue: No ]
    4-point scale.

  • Time to loss of consciousness [ Time Frame: one hour ] [ Designated as safety issue: No ]
    loss of eyelash reflex
