Objective: To investigate the effect of improving the blood circulation speed of injection site by using grip ball movement to relieve the pain caused by intravenous infusion of potassium chloride. Methods: A total of 108 hospitalized patients with hyperemesis gravidarum who were admitted to our department from July 2019 to December 2019 were randomly divided into two groups according to the need for infusion, with 54 cases in the observation group and 54 cases in the control group. Observation group was given potassium chloride infusion, routine intravenous infusion nursing and intermittent grip ball exercise during liquid infusion. The control group received routine intravenous nursing during liquid infusion. Local pain induced by peripheral intravenous infusion of potassium chloride was assessed by digital score (NRS) in both groups. Results: The pain relief in observation group was significantly better than that in control group (P < 0.05); There were fewer phlebitis grades I and II in the observation group, no grades III and IV, and the incidence of phlebitis in the observation group was significantly lower than that in the control group (P<0.05). Conclusion: It can promote blood flow speed, relieve pain and reduce the occurrence of phlebitis by instructing patients to do gripping ball movement during infusion of potassium chloride, it is recommended to promote the application.
