"Spinal anaesthesia is traditionally administered by identifying relevant surface anatomy and imaging is rarely used for pre-procedural identification of structures. Ultrasound-guided anaesthesia in the context of spinal anaesthesia allows for real-time visualisation of anatomical structures, enhancing the accuracy and safety of the procedure, especially in patients with challenging anatomy ref. This technology is particularly valuable for improving the success rate of spinal anaesthesia in patients where traditional surface anatomy identification may be more challenging due to increased soft tissue thickness ref."
"prepare equipment (usually pre-packaged) and use sterile technique"
"post-dural puncture headache (common)"
Expected headings
"Positioning"
"for the parasagittal transverse view, place the transducer 3-4 cm lateral to the spinal processes with the transducer cephalad to the sacrum; the transverse processes and the psoas muscle are best visualised using this view"
