Stable vital signs (SVSs) are thought to be the most important criteria for successful non-operative management (NOM) of blunt spleen injury (BSI). However, a consistent definition of SVSs has been lacking. We wanted to evaluate the diversity of the definitions of SVSs by using a nationwide survey.
A questionnaire regarding the definition of SVSs was sent to the trauma surgeons working at the Department of Trauma Surgery and Emergency Medicine at a level-I trauma center between October 2011 and November 2011. Data were compared using analyses of the variance, t-tests, chi2 tests and logistic regressions.
Among 201 surgeons, 198 responded (98.2%). Of these 198 responses, 45 were incomplete, so only 153 (76.1%) were analyzed. In defining the SVSs, significant diversity existed on the subjects of type of blood pressure (BP), cut-off value for hypotension, technique for measuring BP, duration of hypotension, whether or not to use the heart rate (HR) as a determinant, cut-off value of hypotension when the patient had a comorbidity or when the patient was a child. Of the 153 surgeons whose responses were analyzed, 91.5% replied that they were confused when defining SVSs.
Confusion exists regarding how to define SVSs. Most surveyed surgeons felt that a need existed to clarify both the definition of SVSs and the use of SVSs to determine hemodynamic stability for NOM.
