Objective To investigate the clinical application value of air-lock method in the deltoid intramuscular injection of COVID-19 vaccine. Methods From January 27, 2021 to February 1, 2021, 780 recipients of vaccine were selected as subjects, and they were divided into a control group and a test group, with 390 cases each using a digital sampling method. The control group adopted the conventional injection method, and the test group adopted the air-lock injection method. The rate of blood extravasation or injection solution extravasation and pressing time of the two groups after injection were compared. Results The rate of blood extravasation and injection solution extravasation in the observation group were lower than those in the control group(P＜0. 01). The pressing time after the injection in the observation group was shorter than that of the control group(P＜0. 01). Conclusion The air-lock method in the deltoid intramuscular injection of COVID-19 vaccine can effectively reduce the incidence of bleeding at the injection site and the extravasation of the injection solution, ensure the vaccine injection dose, shorten the pressing time, and reduce the environmental pollution caused by the drug solution extravasation. It is an simple and efficient injection method, which is worthy of promotion and application. (目的 探讨空气闭锁(Air-lock)肌肉注射法在新型冠状病毒灭活疫苗注射中的临床实践与应用价值。方法 2021年1月27日—2月1日, 选取780例接种者作为受试对象, 随机分为对照组(n=390)和研究组(n=390)。对照组采用常规排气注射法, 研究组采用Air-lock注射法。比较两组注射后发生血液和药液渗出情况及按压时间。结果 研究组血液渗出率和药液渗出率均低于对照组, 差异有统计学意义(P＜0. 01)。研究组注射完毕后按压时间短于对照组, 差异有统计学意义(P＜0. 01)。结论 在注射新型冠状病毒灭活疫苗中实施Air-lock注射法, 可以有效的降低注射位置出血及药液外渗, 保证新型冠状病毒灭活疫苗注射剂量、缩短按压时间, 减少药液外渗所致环境污染, 同时操作简单、接种高效的特点, 具有推广应用价值。) |
