Carotid Flow Time Measurement Guided Fluid Management During Spinal Anesthesia

Stopped: Ethical approval not obtained

Turkey (Türkiye)0Started 2022-07

Plain-language summary

Fluid management is a fundamental aspect of anesthesia. Several monitorization methods have been introduced to optimize fuid management. To date neither of them were ideal. Corrected flow time measurement (FTc) in the carotid artery was recently introduced to detect fluid responsiveness. Spinal anesthesia causes hypotension and fluid preloading is suggested to overcome this problem. The aim of this study is to evaluate the effect of FTc guided fluid loading on spinal anesthesia induced hypotension.
