Brief Summary

Point-of-care ultrasound (POCUS) has been found to be useful for aiding in the prediction of fluid responsiveness. It is unknown if trainees can effectively utilize this tool to improve their assessment of fluid responsiveness. In this prospective, observational study, pulmonary and critical care fellows are asked to make 2 assessments of fluid responsiveness in adults with shock: (1) based on clinical exam alone (Clinical) and (2) after performing a POCUS (Clinical + US). The accuracy of their pre- and post-ultrasound assessments are compared using a bioreactance monitor and passive leg raise test as the gold standard of fluid responsiveness in this study.

Conditions

Ultrasound; Shock

Outcome Measures

Primary Outcomes (1)

• Fluid responsiveness

  Increase of stroke volume index greater than 10% following passive leg raise testing

  Immediately subsequent to performance of a point-of-care ultrasound exam

Study Arms (1)

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

* Could undergo both a POCUS and bioreactance assessment within 6 hours of admission from the emergency department or transfer from a medical floor. * Shock was defined as either systolic blood pressure less than 90 mmHg or 40 mmHg below baseline, necessity for vasopressors to maintain mean arterial pressure greater than 65 mmHg, or any evidence of acute organ hypoperfusion that was evident at the time of study enrollment as judged by the treating physician. * The patient needed to be in shock at the time of POCUS and bioreactance testing at time of enrollment in order to be included.

You may qualify if:

• Adults age 18 or older admitted to the MICU with a diagnosis of shock while a fellow was on duty.

You may not qualify if:

• None
