Bedside lung ultrasound can detect pulmonary congestion by detecting the appearance of B-lines. Pulmonary edema may occur even without cardiomyopathy or heart failure, especially after excessive fluid administration. B-lines have been acknowledged as sonographic signs of pulmonary interstitial and alveolar edema in critical and emergency care. Limited scientific evidence on optimal intraoperative fluid management has resulted in large variations of administered fluid regimens in daily practice. The restricted perioperative intravenous fluid regimen reduces complications after elective surgeries, however other studies had shown that intraoperative liberal fluid administration improves postoperative organ functions and recovery and shortens hospital stay after elective surgeries.
