|Post-spinal Anesthesia Hypotension||Diagnostic Test: Ultrasonographic Evaluation of Internal Jugular Vein Cross Sectional Area|
The aim of this study is to evaluate the efficacy of internal jugular cross sectional area for predicting the occurrence of PSAH. Spinal anaesthesia is frequently used in daily clinical practice. Postspinal anaesthesia hypotension (PSAH) is a common side effect with an incidence of 15.3 to 33% that may result in organ hypoperfusion and ischaemic events. Patients' susceptibility to intraoperative hypotension can be influenced by the sensory block level, age, preoperative volume status , physical status, pre-operative medications and fasting.
PSAH due to spinal blockade is principally a consequence of diminished systemic vascular resistance after blockade of preganglionic sympathetic fibres. Many attempts have been tried to prevent PSAH, such as intravenous volume preload or prophylactic vasopressors. However, fluid infusion has been proved to lower the incidence of PSAH and significantly decrease vasopressor requirements. At the same time, empirical volume loading carries the potential of volume overload, particularly in patients with cardiac disease. Consequently, the search for predictors of PSAH is becoming mandatory to avoid blind volume loading and reserve it only for patients who are expected to develop PSAH. .
