Estimating the usefulness of inferior vena cava collapsibility index and caval aorta index to predict hypotension after spinal anaesthesia in adult patients undergoing elective surgery in a tertiary care hospital.

Background And Aims: Post-spinal anaesthesia hypotension (PSAH) can occur in 25-75% of patients. The preload or volume status of a patient is an important contributor to PSAH, and coloading with fluids is advocated to prevent PSAH. Instead of blind volume loading, prediction of volume status using inferior vena cava (IVC) collapsibility index (IVCCI) and caval aorta index (IVC: Ao index) may be used to guide fluid administration.

Effect of dexmedetomidine on characteristics of ultrasound-guided supraclavicular brachial plexus block with levobupivacaine-A prospective double-blind randomized controlled trial.

Background And Aims: Levobupivacaine, a less cardiotoxic s-isomer of bupivacaine, is proved to be similar to bupivacaine, hence, proposed as a safer alternative for nerve blocks. We aimed to evaluate the effect of perineural and intravenous dexmedetomidine on characteristics of ultrasound-guided supraclavicular brachial plexus block (BPB) performed with levobupivacaine. The aim of this study is to evaluate the effect of perineural and intravenous dexmedetomidine on characteristics of ultrasound-guided supraclavicular BPB performed with levobupivacaine.
