Eligibility

Inclusion criteria

Inclusion criteria: 1. Age 18 60 years 2. Scheduled for elective surgery requiring prone positioning 3. Requiring intra-arterial blood pressure monitoring 4. Palpable posterior tibial artery preoperatively 5. Written informed consent obtained

Exclusion criteria

Exclusion criteria: 1. BMI > 30 kg/m 2. Local infection, cellulitis, or wound near the cannulation site, trauma to the medial ankle, cannulation in the same artery/site 3. History of peripheral arterial disease 4. Previous surgery 5. PTA could not be visualised or appear thrombosed during initial scan

Design outcomes

Primary

Measure	Time frame
Compare the first-attempt success rate of ultrasound-guided PTA cannulation between the prone and supine positions in adult surgical patients.Timepoint: Immediately after the first cannulation attempt	—

Secondary

Measure	Time frame
1. Anterior posterior arterial diameter of PTA 2. Ultrasonic assessment time (ultrasound probe contact to skin puncture) 3. Cannulation time (Time from needle insertion to successful catheter placement with backflow) 4. Total procedure time (Includes scanning, puncture, & securing the line) 5. Total Number of attempts for successful cannulation 6. Evaluate complication rates (hematoma, ischemia, arterial spasm, thrombosis) 7. Operator-reported ease/difficulty of cannulation (5-point Likert scale)Timepoint: 1. Immediately prior to skin puncture 2. During the procedure, at the time of cannulation. 3. During the procedure, at the time of successful cannulation. 4. At the completion of procedure. 5. At the completion of procedure 6. Immediately after the completion of the procedure & before shifting the patient. 7. Immediately after completion of the procedure.	—
