In-plane supraclavicular subclavian vein catheterization effective and safe option in critical patients
Tunisia: According to a study published in Annals of Intensive Care, the in-plane supraclavicular subclavian vein technique offers an efficient and secure substitute for the traditional ultrasound-guided out-of-plane internal jugular vein catheterization in critically ill adult patients.
With two main venous pathways, the internal jugular vein (IJV) and subclavian vein, the central venous catheter (CVC) installation is one of the most often performed invasive operations for the management of critically ill patients. The use of US-guidance for IJV cannulation is currently well-established, and the majority of studies have combined an out-of-plane (OOP) needle approach with a short-axis view.
According to the authors, there haven't been any published studies that contrast adult cannulations using the short-axis OOP-IJV and long-axis IP supraclavicular SCV (IP-SSCV).
In order to implant US-guided CVCs in adult intensive care units, this study compared the efficiency and safety of OOP-IJV and IP-SSCV methods.
For this objective, one of two cannulation techniques-ultrasound-guided OOP-IJV or IP-SSCV-was randomly assigned to a group of 250 patients who needed central venous catheterization in quick succession. Three physicians performed all catheterizations. The success rate on the first try was the main result. Additionally recorded were the lengths of time required for ultrasound scanning, venous punctures, insertions, total access, puncture attempts, needle redirections, success rate, guidewire progressing issues, venous collapse, and adverse events.
Key conclusive points:
- In the IP-SSCV group (83.2%) compared to the OOP-IJV group (63.2%), the first attempt success rate was considerably greater (p = 0.001).
- Longer ultrasonic scanning time (16.54 ± 13.51 vs. 5.26 ± 4.05 s; p <0.001) and shorter insertion time (43.98 ± 26.77 vs. 53.12 ± 40.21 s; p = 0.038) were both shown to be related with the IP-SSCV group.
- fewer puncture attempts (1.16± 0.39 vs. 1.47 ± 0.71; p <0.001), needle redirections (0.69± 0.58 vs. 1.17 ± 0.95; p <0.001), guidewire advancement issues (2.4% vs. 27.4%; p < 0.001), venous collapse (2.4% vs. 18.4%; p < 0.001), and adverse events (8.8%vs. 13.6%; p = 0.22) were observed.
"The IP-SSCV cannulation is a safe and effective technique for performing and teaching CVC insertion in adult intensive care units,, with a higher first attempt success rate, a lower rate of difficulties with guidewire insertion, and a lower incidence of hematoma at the puncture site than with the OOP-IJV cannulation," asserted the authors.
The IP-SSCV strategy offers a promising alternate technique for central venous catheterization, according to the authors' analysis. For its routine usage in daily practice, more clinical research is required.
