Comparison Of Ultrasound-Based Measures Of Inferior Vena Cava And Internal Jugular Vein For Prediction Of Hypotension During Induction Of General Anesthesia

Hypotension after induction of general anesthesia is a frequent event in routine practice. Even a short period of hypotension may lead to tissue hypoperfusion and predispose to postoperative complications. Intra-operative hypotension is associated with renal injury, ischemic stroke, myocardial injury and postoperative mortality in patients having non-cardiac surgery under general anesthesia. Underlying hypovolemia is an important and modifiable risk factor for hypotension after anesthetics administration. Ultrasonographic studies of the inferior vena cava (IVC) and the internal jugular vein (IJV) for evaluation of intravascular volume status and prediction of hypotension during induction of general anesthesia have been established. The present study was designed to compare, on ultrasound-based measures, between inferior vena cava and internal jugular vein for prediction of prolonged hypotension during induction of general anesthesia. The study was conducted at Kasr Al-Ainy hospital, Cairo University in Patients undergoing elective non-cardiac surgery under general anesthesia.
