Pulse Transit Time in Anesthetized Patients: Blood Pressure or Cardiac Output as Measured With NICOM Monitor

NCT01259687 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 63

Last updated 2013-11-26

No results posted yet for this study

Summary

Pulse transit time (PuTT) - the time between R wave on ECG and initiation of upstroke in the peripheral arterial waveform - described in the previous studies as value that reflects changes in both blood pressure and blood volume. The investigators are assuming that PuTT changes reflect the dynamic of systolic blood pressure but not cardiac output fluctuations.

Conditions

  • Anesthetized Ventilated Patients

Interventions

DEVICE

Non-invasive cardiac output monitoring

During the surgery the continuous monitoring of blood pressure by peripheral artery catheter and cardiac output by NICOM (non-invasive cardiac output monitoring) will be applied. In case of intraoperative hemodynamic changes (hypertension, hypotension) the patient will be treated according to the standard care by Phenylephrine, Nitroglycerine or Colloid fluid boluses. Cardiac output will be measured by NICOM just before and after each treatment of hemodynamic events that described above. Simultaneous records of ECG, arterial and plethysmographic waveforms will be made just before and after each event. Systolic blood pressure and PuTT will be measured OFFLINE from the recorded waveforms
