Further study details as provided by Centre hospitalier de l'Université de Montréal (CHUM):

Primary Outcome Measures:
  • define the correlation coefficient between the number of systemic and/or cerebral desaturation phases and the number of postoperative adverse events [ Time Frame: from the beginning of anesthesia till 4 hours after the end of the surgery ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • define the prevalence of systemic and cerebral desaturation phases during hepatic surgery or transplantation [ Time Frame: from the beginning of anesthesia till 4 hours after the end of the surgery ] [ Designated as safety issue: No ]
  • define the correlation coefficient between systemic and/or cerebral desaturation phases and the length of stay in intensive care unit [ Time Frame: duration of intensive care stay, an expected average of 4 days ] [ Designated as safety issue: No ]
  • validate the equivalence of the systemic and cerebral oxymetry [ Time Frame: from the beginning of anesthesia till 4 hours after the end of the surgery ] [ Designated as safety issue: No ]

Intervention Details:
    Other: systemic and cerebral oxymetry
    oxymetry measurement using near infrared spectroscopy
    Other Name: oxymetry measurement using near infrared spectroscopy
Detailed Description:

This is an observational study. Cerebral and systemic oxymetry (rSO2) using near infrared spectroscopy (NIRS, Invos 5100; Somanet- ics Corporation, Troy, MI) will be performed on all patients with 4 optodes (right and left temporal area, arm and leg). Continuous rSO2 values will be stored on a hard disk with a 15 seconds update within intraoperative period and first 4 hours after the surgery. Desaturation phases (saturation decrease more than 20% of the basal value for more than 15 seconds) will be correlated to operative procedure or events. Postoperative adverse events will be collected. A correlation between desaturation and postoperative adverse events will be done with a multiple linear regression model.
