NCT03027323

Brief Summary

Undifferentiated hypotension is a medical emergency where a patient's blood pressure drops to critical levels due to several possible reasons. The medical staff treating the patient will need to find out the reason for your drop in blood pressure as soon as possible. When treating low blood pressure, the medical staff typically performs a procedure called central venous cannulation (CVC). CVC involves accessing a large vein (usually the subclavian under the collarbone) by inserting a needle into the vein. By doing this, the medical staff can measure the pressures in the patient's veins or give medicine to the patient while they are in the hospital. The purpose of this study is to compare the time needed to complete CVC using the AxoTrack device to CVC guided by landmarks on a patient's body. The investigators expect that there will be a maximum of 30 patients enrolled in this study.

Outcome Measures

Primary Outcomes (1)

  • Time to insertion of CVC into a subclavian vein

    The time it takes for the care provider to insert the central venous cannulation device into the subclavian vein

    0-30 minutes

Study Arms (2)

AxoTrack System guided CVC insertion

OTHER

AxoTrack System guided CVC

Device: AxoTrack System

CVC insertion guided by landmark

NO INTERVENTION

Anatomical landmarks to guide CVC

Interventions

The AxoTrack system is a novel ultrasound guidance system intended to facilitate central venous cannulation (CVC) by a single operator as well as to reduce complications and time associated with CVC. The AxoTrack has a small ultrasound scan head which facilitates imaging of the subclavian vein.
