Rieser et al reported a score to identify a patient with pathologic pneumatosis. This can help to identify a patient who requires urgent surgery. The authors are from the University of Pittsburgh.
Parameters:
(1) age in years
(2) heart rate in beats per minute
(3) blood lactate in mmol/L
(4) neutrophil-to-lymphocyte ratio (NLR)
(5) small bowel pneumatosis intestinalis
