IntroductionAbout 2%–30% of cardiac catheterisation procedures get complicated by radial artery occlusion (RAO). Ensuring patent haemostasis appears to be an important factor in reducing RAO. Currently employed method is a radial compression device (RCD) such as transradial band (TRB) that take hours to achieve haemostasis and cause discomfort to the patients. Haemostatic pads offer an alternative to RCD with reduced time to achieve haemostasis. Our trial aims to determine the non-inferiority of the catecholamine chitosan-based pad (InnoSEAL haemostatic pad) used in conjunction with TRB (InnoSEAL +TRB) when compared with the TRB alone in reducing composite adverse access site outcomes.Methods and analysisIt will be an open-label, parallel, randomised controlled trial on 714 adult patients (325 in each arm) undergoing coronary procedure using transradial approach at a cardiac health facility over 7 months duration. InnoSEAL patch along with TRB will be used to control bleeding in intervention arm and TRB alone in control arm, which is the standard practice. Study primary outcomes include RAO and haematoma; secondary outcomes are compression time, patient discomfort, time to discharge and ease of use of the intervention technique by the healthcare staff. χ2 test will be used to compare the categorical outcomes between two arms and student’s t-test for continuous outcomes. A p value of <0.05 will be considered significant.Ethics and disseminationEthical approval for the study has been obtained from the Institutional Review Board of Tabba Heart Institute number IORG0007863. Findings will be disseminated through seminars and scientific publications.Trial registration numberNCT04380883; Pre-results.

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.

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).

Abstract BackgroundTo compare the short-axis/out-of-plane (SAX), long-axis/in-plane (LAX) and oblique-axis/out-of-plane (OAX) approaches for radial artery catheterization performed by anaesthesia residents with limited experience.MethodsTwo hundred and sixteen adult patients were scheduled to undergo surgery requiring continuous arterial pressure monitoring. They were randomized to the SAX, LAX and OAX groups at a 1:1:1 ratio. Thirty-three anaesthesia residents performed the cannulation procedures. The operators received an explanation of the theoretical anatomy of the radial artery and the operating process of three approaches for ultrasound-guided cannulation of the radial artery and practised artery cannulation on a model of radial artery cannulation. The primary outcome was the success rate of cannulation, and the secondary outcomes included the first-attempt success rate in the model and patients, the imaging time, blood return time, cannulation time, total time and incidence of adverse events.ResultsThe success rate of radial artery cannulation in the SAX group was significantly higher than that in the LAX group (71.4% vs 49.2%; P=0.009) and was clinically meaningfully higher than that in the OAX group (71.4% vs 61.7%; P=0.229). The total time was shorter in the SAX group than in the LAX and OAX groups: 51 (59) s vs 113 (66) s vs 86 (61) s; P=0.000. The first-attempt success rate for the model did not differ among the three groups. In the patients, the first-attempt success rate in the SAX group was significantly higher than those in both the LAX and OAX groups (69.7% vs 24.2% vs 6.1%; P=0.000).ConclusionAnaesthesia residents can achieve a higher success rate, higher satisfaction rate and shorter procedure time by using the SAX approach than by using the LAX and OAX approaches for radial artery catheterization.Trial registrrationChinese Clinical Trial Registry,ChiCTR200030416.
