In<br />group I, arterial line was inserted using the blind palpation technique. While in<br />group II, arterial line was inserted with the help of ultrasound guidance. The primary<br />endpoints were time of insertion in 1st attempt, number of first successful<br />attempts and maximum number of attempts used for insertion of arterial line.<br />Data was analyzed by using SPSS V23. Chi-square test was used for analysis of<br />gender and successful insertion in 1st attempt. Independent sample t-test and<br />Mann-Whitney U-test were used to compare quantitative variables.<br />Results: Mean baseline systolic blood pressure, mean diastolic blood pressure<br />and mean pulse rate before surgery were also not significantly different between<br />the groups. Arterial line was inserted in first attempt in in 88.0% patients<br />in ultrasound guided group and in only 70.0% patients in blind palpation group<br />(p-value 0.027). Arterial line insertion time in 1st attempt was also significantly<br />less in ultrasound guided group 77.68±7.98 seconds versus 95.46±15.53 seconds<br />in blind palpation group (p-value <0.001). We also found less number<br />of attempts 1.16±0.37 in ultrasound guided group versus 1.44+0.67 in blind<br />palpation group (p-value 0.025).<br />Conclusion: Ultrasound guided radial artery cannulation is associated with<br />higher rate of successful insertion and less time is required for arterial line insertion<br />as compared to blind palpation method.}, number={1}, journal={Journal of Postgraduate Medical Institute}, author={Ammar, Ali and Ali, Liaqat and Furqan, Aamir}, year={2017}, month={Feb.} }
