Previous studies have demonstrated that altered microvascular blood flow is an important marker of severe sepsis. Usually, these patients need invasive ventilatory support, frequent use of sedatives and it is unknown if these agents interfere or not on microvascular blood flow. The goal of this study was to compare effects of propofol and midazolam infusions on sublingual microcirculation of septic shock patients.

Condition Intervention
Drug: Sedation drug (Propofol and Midazolam)

Primary Outcome Measures:
  • Sublingual Microcirculatory Variables [ Time Frame: Just before stopping propofol and thirty minutes after the start of midazolam infusion ] [ Designated as safety issue: No ]
    Patients were sedated with propofol during the first 24 hours after intubation and with midazolam afterwards.Systemic hemodynamics and perfusion parameters were assessed at two time points: just before stopping propofol and thirty minutes after the start of midazolam infusion. At both steps, four microcirculatory sequences were acquired using sidestream darkfield imaging to access sublingual microcirculation

Enrollment: 16
Study Start Date: March 2011
Study Completion Date: August 2011
Primary Completion Date: August 2011 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Sedation drug (Propofol and Midazolam)
    Septic patients, after intubation, were initially sedated with propofol. During the second day of mechanical ventilation, propofol infusion was interrupted. When the patient awoke, the sedative drug was changed to midazolam. Sedation target was a Ramsay Scale score of 4 to 5.
