    Abstract:
    BACKGROUND: Compared with blind technique, ultrasound (US) transducer-guided technique for radial artery puncture can improve the success rate. However, difficulty in handling US transducer-guided technology is a key limitation to its wider use. The aim of the study was to explore the effect of guide marks on the side of US transducer on the success rate of US transducer-guided radial artery puncture. METHODS: In this parallel-group trial, 127 patients undergoing elective liver cancer resection and splenectomy under general anesthesia were randomly allocated to the traditional group or the Intervention group. The traditional group used the conventional US transducer-guided radial artery puncture technology, while the Intervention group used the US transducer-guided radial artery puncture technology with the guide marks on the side of the US transducer probe. The primary observation index was success rate of radial artery cannulation at the first attempt; the secondary observation indices were failure rate of cannulation, location time, and total time for successful cannulation. RESULTS: The successful rate of cannulation in the Intervention group (59 out of 63, 93.6%) was greater than that in the traditional group (50 out of 64, 78.1%, p = 0.01). The posterior wall puncture rate in the Intervention group was lower than that in the traditional group (11.1% vs 32.8%, p = 0.005). The location time in the Intervention group was longer than that in the traditional group (20.1 ± 3.8 vs 16.6 ± 4.0 s, p < .001), while the total cannulation time was significantly shorter (20.7 ± 4.3 vs 32.4 ± 7.4 s, p < 0.001). CONCLUSION: Using guide marks on the side of US transducer can help improve success rate of US transducer-guided radial artery puncture at the first attempt and reduce the risk of puncture-related complications.
