概要
This study aims to assess the accuracy, repeatability, and reproducibility of preoperative evaluation of Inferior Vena Cava (IVC) collapsibility index and caval aorta index for prediction of hypotension after induction of general anesthesia.
詳細説明
Post- anesthesia hypotension is of common occurrence, and it hampers tissue perfusion. The magnitude of hypotension is determined by the preoperative volume status, which varies depending on American Society of Anesthesiologists (ASA) physical status, preoperative comorbidities, preoperative medications, and fasting.
General anesthesia causes significant alterations in hemodynamics, as both inhalational and intraven...

Study group Patients scheduled for elective craniotomy surgeries before induction of general anesthesia. | Inferior vena cava collapsibility index Inferior vena cava (IVC) collapsibility index (IVCCI) will be measured.
The IVCCI is calculated using the following formula:
IVCCI = (maximum IVC diameter - minimum IVC diameter) / maximum IVC diameter \* 100 Caval Aorta Index The Inferior vena cava (IVC): Ao index will be derived by taking the ratio of the maximum IVC diameter during expiration and the maximal abdominal aortic diameter during systole.
\- The caval aorta index (IVC/Ao) is calculated using the following formula: IVC/Ao index = IVC diameter / aortic diameter. |
