Ultrasound-guided radial artery cannulation using dynamic needle tip positioning versus conventional long-axis in-plane techniques in cardiac surgery patients: a randomized, controlled trial

Abstract Background: Given the low first-pass success rate of the conventional short-axis (SAX) or long-axis (LAX) approach, ultrasound-guided radial artery cannulation in adults with radial artery diameters less than 2.2 mm may still be challenging. In this study, we compare the efficacy of modified long-axis in-plane(M-LAIP) versus short-axis out-of-plane (SAOP) or conventional palpation(C-P) approaches for ultrasound-guided radial artery cannulation.Methods: This was a prospective, randomized and controlled trial, conducted from 1 July 2018 to 24 November 2018. A total of 201 patients (age 18 to 85 years, the diameter of the radial artery less 2.2 mm) were included. All patients were randomized 1:1:1 to the M-LAIP, SAOP or conventional palpation (C-P) approach. The primary outcome was the cannulation success rate. Secondary outcomes included first location time and cannulation time, number of attempts. The Chi-square (χ2) test was used to compare categorical data between 3 groups.Results: The cannulation success rate was significantly higher in the M-LAIP group than in the SAOP or C-P groups (first success rate: 80.3% vs 53.8% or 33.8%; p < 0.001; total success rate: 93.9% vs 78.5% or 50.8%; p < 0.001). First location time (seconds) was significantly longer in the M-LAIP group (31(28-35[12-44])) than in the SAOP (15(14-17[10-21]); p < 0.001) and C-P groups (12(8-13.5 [6-37]). However, the cannulation time (seconds) in the M-LAIP group (29(24-45[16-313])) was significantly shorter than that in the SAOP (45(28.5-135.5[14-346]); p = 0.002) and the C-P groups (138(27-308[12-363]); p < 0.001). The number of attempts was lower in the M-LAIP group compared with SAOP or C-P group (1.29±0.63 vs 1.8±0.89 or 2.22±0.93, p < 0.001).Conclusions: The use of the M-LAIP approaches significantly improved the success rate of radial artery cannulation in adults with radial artery diameters less than 2.2 mm, compared with that achieved with the use of traditional short-axis out-of-plane approach.Trial registration: ClinicalTrials.gov; No: ChiCTR-IOR-17011474; URL: http: // www. chictr.org. cn/index.aspx.

Abstract Background Radial artery cannulation can cause complications such as haematoma formation or thrombosis due to its small diameter. Recently, a novel ultrasound device equipped with an electromagnetic guidance system was introduced, showing the path and alignment of the needle during the procedure. The aim of this study was to investigate the effects of this novel system on both success and complication rates during radial artery cannulation under ultrasound guidance. Methods In this randomized controlled trial, 76 adults scheduled for neurosurgery requiring radial artery cannulation were recruited. In group E (n = 38), radial artery cannulation was performed using the electromagnetic guidance ultrasound system, whereas in group C (n = 38), the procedure was performed using conventional ultrasound guidance. The success rates of cannulation on the first attempt, cannulation times, number of attempts, and incidence of complications were compared between the two groups. Results There was a significant difference in the success rates on the first attempt between the two groups (group C = 78.9% vs. group E = 94.7%, P = 0.042). Incidences of posterior wall puncture and haematoma formation (group C = 8 vs. group E = 1; P = 0.028) were significantly lower in group E than in group C. The median cannulation time for successful attempts was comparable between groups. Conclusions Use of the novel electromagnetic guidance system resulted in a better success rate on the first attempt and a lower incidence of complications during radial artery cannulation.

BACKGROUNDGiven a low first-pass success rate of the conventional SAX (short-axis) or LAX (long-axis) approach, ultrasound-guided radial artery cannulation in adults with radial artery diameter less than 2.2 mm may be still challenging.OBJECTIVETo assess the efficacy of modified long-axis in-plane(M-LAIP) versus short-axis out-of-plane (SAOP) or conventional palpation(C-P) approaches for ultrasound-guided radial artery cannulation.DESIGNA prospective, randomized and controlled trial.SETTINGOperating room in a tertiary university hospital, from 1 July 2018 to 24 November 2018.PATIENTSA total of 201 patients (age 18 to 85 years, the diameter of the radial artery less 2.2 mm) were included. Patients with history of forearm surgery, ulnar artery occlusion, abnormal Allen test, etc, were excluded from this study.INTERVENTIONSAll patients were randomized 1:1:1 to M-LAIP, SAOP or C-P.MAIN OUTCOME MEASURESThe primary outcome was the cannulation success rate. Secondary outcomes included first location time and cannulation time, number of attempts.RESULTSThe cannulation success rate was significantly higher in the M-LAIP group than in the SAOP group or C-P group (first success rate: 80.3% vs 53.8% or 33.8%; p =0.000; total success rate: 93.9% vs 78.5% or 50.8%; p =0.000). First location time (s) was significantly longer in the M-LAIP group compared with the SAOP group (31(28-35[12-44]) vs 15(14-17[10-21]); p =0.000) and the C-P group (31(28-35[12-44]) vs 12(8-13.5 [6-37]); p =0.000). However, the time of cannulation in the M-LAIP group (29(24-45[16-313])) was significantly shorter than that in the SAOP group (45(28.5-135.5[14-346]), p =0.002) and in the C-P group(138(27-308[12-363]), p =0.000). The number of attempts decreased in the M-LAIP group compared with SAOP or C-P group (1.29±0.63 vs 1.8±0.89 or 2.22±0.93, p =0.000).CONCLUSIONThe M-LAIP procedure for ultrasound-guided radial artery cannulation can offer a higher success rate of the first-attempt and total cannulation, fewer attempts and less time of cannulation.TRIAL REGISTRATIONThe study was registered at ClinicalTrials.gov (http://www.chictr.org.cn/index.aspx, number: ChiCTR-IOR-17011474).
