Study Details

Study Description

Brief Summary

PiCCO has been widely used in critical care settings for several decades. Together with pulmonary artery catheter, it is regarded as the important tool for guiding fluid management in patients with shock or acute respiratory distress syndrome. However, its effects on patients' outcome remain untested. The investigators study is a pilot study that is designed to test whether the use of PiCCO will improve patients' outcome, as compared to those without PiCCO monitoring.

Condition or Disease Intervention/Treatment Phase
  • Device: PiCCO monitoring (PULSION)
  • Procedure: central venous catheter
Phase 1/Phase 2

Detailed Description

PiCCO comprises techniques of pulse contour analysis and transpulmonary thermodilution, and can provide important information on hemodynamics and pulmonary functions. It has been widely used in critical care settings for several decades. Together with pulmonary artery catheter (PAC), it is regarded as the important tool for guiding fluid management in patients with shock or acute respiratory distress syndrome. During last two decades, many well designed clinical trials have been conducted to see whether the use of PAC would benefit patient outcome. The result consistently showed that PAC added no benefit in terms of mortality, ICU length of stay, organ failure free survival days, and the length of mechanical ventilation. Since PiCCO is relatively new to PAC, and its effects on patients' outcome remain untested. The investigators study is a pilot study that is designed to test whether the use of PiCCO will improve patients' outcome, as compared to those without PiCCO monitoring.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: intervention arm

patients allocated to intervention arm receive PiCCO monitoring for hemodynamics and pulmonary conditions

Device: PiCCO monitoring (PULSION)
Patients are monitored with PiCCO system.
Other Names:
  • PiCCO (pulsion medical system, PULSION PiCCO plus)
  • Placebo Comparator: control arm

    Patients in this arm do not receive PiCCO monitoring device to guide fluid management, but central venous catheter can be inserted at the discretion of treating physician.

    Procedure: central venous catheter
    patients in this arm can receive central venous catheter

    Outcome Measures

    Primary Outcome Measures

    1. 30 day mortality [30 days]

      death from any cause before day 30

    Secondary Outcome Measures

    1. 14 day mortality [14 days]

      patients were followed up for 14 days

    2. ICU length of stay [up to 30 days]

      the time from ICU admission to ICU discharge or death

    3. days on mechanical ventilation [up to 30 days]

      days during which the patients are on mechnical ventilation: The criteria for termination of mechanical ventilation: a cooperative patient, recovery from primary disease, hemodynamically stable, adequate and strong cough reflex, positive end-expiratory pressure <5 cmH2O, pressure support <10 cmH2O and the spontaneous breathing trial is successfully passed.

    4. days of vasoactive agents support [up to 30 days]

      days during which vasoactive agents are used: The sum of the number of days with one or more vasoactive agents to maintain a mean arterial pressure >60 mmHg

    5. ICU free survival days during 30-day period [30 days]

      ICU free survival days during 30-day period

    6. mechanical ventilation free survival days during 30-day period [28 days]

      mechanical ventilation free survival days during 30-day period
