Introduction: Ultrasound is a currently used tool for central venous cannulation. Short-axis (SAX) and long-axis (LAX) vision have been described for cannulation of the internal jugular vein (IJV). In our population, few studies have described its perioperative usefulness.
Objectives: characterize two ultrasound views for cannulation of the internal jugular vein in adult patients undergoing cardiac surgery in a health center in Colombia.
Methods: 25 patients were included for the SAX subgroup and 25 patients for the LAX subgroup. The following results were recorded: (1) first pass success rate (2), IJV access time, (3) identification of the anterior wall of the IJV > 50% of its diameter, (4) incidence of puncture of the posterior wall of the IJV and (5) the incidence of complications (arterial puncture, hematoma and arrhythmias).
Results: In 100% of the patients in the SAX group, success was achieved on the first attempt when punctured the IJV compared to 92% in the LAX group, without statistical significance (p=0.149). The times to access the IJV for the SAX group were 13.28 ± 2.372 seconds and for the LAX group 14.12 ± 4.256 seconds (p=0.556).
Conclusions: Of the US, SAX and LAX views, it is still not clear which is superior when compared, a larger sample is needed to achieve statistically significant results.
