Ultrasonic Technology Improves Radial Artery Puncture and Cannulation in Intensive Care Unit (ICU) Shock Patients.
BACKGROUND This study observed the efficacy of ultrasonic technique with out-of-plane orientation and in-plane guidance in radial artery puncture and cannulation in intensive care unit (ICU) shock patients to elucidate the effect of this technique on the security of cannulation. MATERIAL AND METHODS A total of 88 ICU shock patients, randomized into a palpation (control) group and an ultrasound (experimental) group, received continuous intravenous sedation and analgesia. ⋯ RESULTS (1) The success rate of the first puncture in the ultrasound group and the palpation group was 80% and 42%, respectively (P<0.05). (2) The cannulation duration in the ultrasound group and the palpation group was 8.77±6.33 s and 28.7±26.33 s, respectively (P<0.01). (3) Incidence of hematoma and staxis around stoma in the ultrasound group was 2.5% and 5%, respectively, which was significantly lower than that in the palpation group, which was 20% and 32.5%, respectively (P<0.05). (4) Time to achieve the early goal-directed therapy in the ultrasound group and the palpation group was 306.73±39.98 min and 356.75±40.97 min, respectively (P<0.01). CONCLUSIONS Compared with the traditional method, radial artery cannulation with out-of-plane orientation and in-plane guidance is a quick and secure cannulation method and is appropriate for use in clinics.
