Ultrasound IDs Pregnant Women With Respiratory Risk
(HealthDay News) — In parturients with severe preeclampsia, lung ultrasound can detect pulmonary edema and elevated left ventricular end-diastolic pressures, according to a study published in the April issue of Anesthesiology.
Laurent Zieleskiewicz, MD, from Aix Marseille University in France, and colleagues prospectively studied 20 parturients with severe preeclampsia and 20 healthy control parturients. Lung and cardiac ultrasounds were performed before and after delivery.
The researchers found that lung ultrasound detected interstitial edema in five (25%) parturients with severe preeclampsia. Increased mitral valve early diastolic peak E (P=0.05) and elevated E/E' ratio (P<0.001) were significantly associated with a B-pattern. An elevation of filling pressures (E/E' ratio >9.5) was predicted by an Echo Comet Score >25 with a sensitivity of 1.00 (95% confidence interval, 0.60–1.00) and specificity of 0.82 (95% confidence interval, 0.66–0.92).
"In our parturients with severe preeclampsia, lung ultrasound detects pulmonary edema and elevated left ventricular end-diastolic pressures," the authors write.
