BACKGROUND: Efficient identification of dysvascular finger(s) following @entity130 is critical for triaging surgical care and optimizing @entity1 outcomes. We designed a study evaluating an objective measure of digital @entity519 followed by surgical exploration and correlation with @entity1317 . METHODS: @entity1 with lacerating or penetrating @entity130 to the hand or digits were examined. A pulse oximeter was applied to the injured digit, and the @entity26 saturation was recorded.As the distribution of pulse oximetry measurements did not approach normality, nonparametric Wilcoxon rank-sum test was used to assess for difference in pulse oximetry for digits with and without an @entity63 that required repair. Receiver operator characteristic curve (ROC) analyses were used to determine cut-points. RESULTS: Twenty @entity1 with digital lacerations were enrolled, with a total of 49 digit measurements of pulse oximetry. Twelve @entity130 requiring repair or amputation were confirmed in the operating room.There was a significant difference in pulse oximetry measurement in digits with (76%; 95%CI 64-87) and without (98%; 95%CI 97-99) @entity63 (P < 0.001). Injured digits ranged in oximetry from 53-92%. CONCLUSIONS: Pulse oximetry is widely available, and offers an objective measure of tissue oxygenation. In our study, no digit with a pulse oximetry of at least 95% had an @entity63 , and all digits with a pulse oximetry of 84% or lower required operative vascular treatment. Based on this data, pulse oximetry should be adopted as a routine measure for the evaluation and communication of a potentially dysvascular digit. LEVEL OF EVIDENCE: III.
