Association Between Profound Shock Signs and Peripheral Intravenous Access Success Rates in Trauma Patients in the Prehospital Scenario: A Retrospective Study
Authors' conclusion
The presence of profound shock in trauma patients in the prehospital scenario is associated with an increased number of attempts required for IV access establishment.
Study context
- Population
- Prehospital trauma patients treated by IDF medical forces with intravenous (IV) access attempted, January 2020–April 2022 (excluded: <16 years, nonurgent, no detectable heart rate or BP)15.7% profound shock
- Participants
- 537 patients
- Exposure
- Profound shock vs no profound shock signs
- Outcome
- Number of attempts required for first IV access success (ordinal: 1, 2, 3 and higher, ultimate failure)
Methodological detailsregistry-based, multivariable ordinal logistic regression
- Registry-based
- Multivariable ordinal logistic regression
Main finding
As reported in the abstract
Profound shock vs NonshockEstimate (CI)
Univariable analysis
OR for requiring an increased number of IV attempts (univariable) 1.94(1.17–3.15)
Multivariable ordinal logistic regression
aOR for worse primary outcome (more IV attempts) 1.84(1.07–3.10)
Observational data: associations, not effects.
