Robert-Ebadi et al reported the Pregnancy-Adapted Geneva (PAG) score for estimating the probability of a pulmonary embolism in a pregnant woman. This is derived from the Geneva score. The authors are from multiple institutions in Switzerland, France and Canada.
Patient selection: pregnant woman with suspected pulmonary embolism
Parameters:
(1) age in years
(2) surgery under general anesthesia or lower limb fracture in the past 30 days
(3) history of previous deep vein thrombosis or pulmonary embolism
(4) unilateral lower limb pain
(5) hemoptysis
(6) pain on palpation of the lower limb with unilateral edema
(7) heart rate in beats per minute
