Lung Ultrasound in Critically Ill Obstetrics and Gynecological Patients

"ultrasound assessment within 24 hours. Then reassessment every 48 hours or when the patient develops respiratory distress.~While the patient is in a supine or semi-recumbent position, and the probe is in a short axis. The 8-region technique will be used. The areas are four on each side of the chest. The examiner will assess 8 regions -Anterior chest wall ( ACW), Anterior axillary line (AAXL), costo-phrenic angle (COSTO), Postero-lateral alveolar \&/ or pleural syndrome (PLAPS) right and left . Each region will be scored using the LUS aeration score. as follows: 0, A-pattern with 0-2 B-lines; 1, more than 2 separated B-lines; 2, multiple coalescent B-lines; or 3, lung consolidation, . A global LUS score will be calculated at each time point and range from 0 to 24.~posterior region will be assessed if needed and if feasible. The venous status will be assessed through a subcostal view for inferior vena cava diameter."
