Validation of Nicom Device to Measure Stoke Volume Variation (NICOM-VAL)

January 26, 2018 updated by: Hopital Foch

Validation of NICOM for the Detection of Modification of Stroke Volume

The purpose of this study is to evaluate the ability of NICOM (Noninvasive cardiac output monitor) to detect stroke volume variation induced by leg raising or fluid expansion during surgery

How is the study designed?

Design Details

  • Primary Purpose: Diagnostic
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Low volume

The protocol will follow the following steps :

  • basal measurements (heart rate, arterial pressure, stroke volume estimated by esophageal Doppler, stoke volume estimated by Nicom)
  • followed by passive leg rising and additional measurements (heart rate, arterial pressure, stoke volume estimated by esophageal Doppler, stoke volume estimated by Nicom)
  • second basal measurements (heart rate, arterial pressure, stoke volume estimated by esophageal Doppler, stoke volume estimated by Nicom)
  • followed by low volume loading (250 ml of Ringer solution) and additional measurements (heart rate, arterial pressure, stoke volume estimated by esophageal Doppler, stoke volume estimated by Nicom)
Procedure: Volume loading
Volume loading with Ringer Lactate
Drug: Ringer solution
Experimental: High volume

The protocol will follow the following steps :

  • basal measurements (heart rate, arterial pressure, stroke volume estimated by esophageal Doppler, stoke volume estimated by Nicom)
  • followed by passive leg rising and additional measurements (heart rate, arterial pressure, stoke volume estimated by esophageal Doppler, stoke volume estimated by Nicom)
  • second basal measurements (heart rate, arterial pressure, stoke volume estimated by esophageal Doppler, stoke volume estimated by Nicom)
  • followed by low volume loading (500 ml of Ringer solution) and additional measurements (heart rate, arterial pressure, stoke volume estimated by esophageal Doppler, stoke volume estimated by Nicom)
Procedure: Volume loading
Volume loading with Ringer Lactate
Drug: Ringer solution
