Objective To investigate the effects of two different arm postures on radial artery puncture. Methods We randomly divided 100 patients into control group and experiment group according to the operation sequence, 50 patients in each group. In the control group, the traditional method was used for radial artery puncture and sheath placement, while in the experiment group the modified method was used. Result Compared with the control group, the success rate of radial artery puncture in the experiment group was significantly higher (P<0.05), and the time needed was significantly shorter (P<0.05). Conclusions The modified arm posture for radial artery puncture and sheath placement is more effective for exposure of the radial artery puncture point and ensure the stability of the puncture site. With this method, we can improve the success rate of radial artery puncture and shorten the puncture time. It is worthy of clinical application.

As an important measure starting for hospital management, hospital accreditation can effectively guide hospitals to improve their comprehensive service capabilities and management level. The accreditation results of 38 tertiary general hospitals in Jiangsu province from 2018 to 2020 showed that there were weaknesses existing in the development of hospitals, including the radiosity and influence of tertiary hospitals, patient service mode, construction of medical technology capabilities and disciplines, medical quality and safety, nursing quality management and specialized nursing, and information construction. The author suggested that hospitals should return to functional positioning, improve the service quality, strengthen construction of hospital disciplines and technical projects, consolidate the foundation of quality and safety management, improve the level of information technology construction, for references for promoting the high-quality sustainable development of tertiary general hospitals.
