After induction, under General Anaesthesia, arterial lines were placed following an aseptic technique using ultrasound or palpatory method; in Group-U (ultrasound) or Group-P (Palpation),respectively. Demographic variables of the patient along with hemodynamic readings and success rate at first or multiple attempts, along with the total time of cannulation, were recorded.</p> <p><strong>Results:</strong> Out of the total 74 patients, 59(79.7%) patients belonged to ASA-1 Grade, and 15(20.3%) patients in ASA-2 Grade. The mean age of the patients was 48.3±16.3, while mean BMI was 25.42±2.8kg/m2. In Group-P, the first-pass success was achieved in 19(51.4%) patients as compared to 32(86.5%) in Group-U when ultrasound was used (p<0.05).</p> <p><strong>Conclusion:</strong> The success rate in placing an arterial line using ultrasound was significantly greater than the conventional palpatory method. Therefore, ultrasound should be a preferred modality during intra-arterial line placement.</p>}, number={6}, journal={Pakistan Armed Forces Medical Journal}, author={Khan, Taimur Azam and Ali Shah, Syed Qasim and Riaz, Muhammad Mohsin and Mateen, Osama Abdul and Beg, Mirza Hamid and Sharif, Muhammad Huzaifa}, year={2022}, month={Dec.}, pages={2147–50} }
