Abstract Hypotension is a common side effect during induction of general anesthesia, and if severe, it results in many complications. Patients’ susceptibility to intra-operative hypotension can be affected by many pre-operative factors, as the pre-operative volume status that may differ according to comorbidities, physical status, pre-operative medications and pre-operative fasting hours. Various parameters have lately been investigated to determine the intravascular volume status prior to surgery. Ultrasonography of inferior vena cava (IVC) is a reliable noninvasive tool that can be used as an indicator of intravascular volume status. The current study aimed to compare the efficacy of both pre-operative inferior vena cava collapsibility index (IVCCI) and inferior vena cava to aorta diameter (IVC:Ao ratio index) for prediction of post general anaesthesia induction hypotension (PGAH). After obtaining written informed consent from all patients, 102 patients of both sexes, American Society of Anesthesiologists’ physical status 1 or 2 scheduled for elective surgery under general anaesthesia were included in this study. We concluded that Pre-operative IVCCI and IVC:Ao index are good predictors of the occurrence of PGAH. However, IVC:Ao index is a more powerful predictor than IVCCI. |
