前导后冲法静脉滴注加温后20%甘露醇注射液预防静脉炎的临床观察

Clinical Observation of Intravenous Dripping of Heated 20% Mannitol Combined with before and after Intravenous Infusion of Normal Saline for Preventing Phlebitis

目的:观察前导后冲法静脉滴注加温后20%甘露醇注射液预防静脉炎的临床效果。方法:将120例接受20%甘露醇注射液静脉滴注治疗的患者随机均分为观察组与对照组:观察组采用前导后冲法静脉滴注加温至(35±1)℃的20%甘露醇注射液;对照组采用常规法静脉滴注室温下((14±5)℃)20%甘露醇注射液。观察2组局部血管和组织的改变情况。结果:观察组患者主观不适和静脉炎的发生率(13.33%)均显著低于对照组(63.33%)(P<0.01)。结论:前导后冲法静脉滴注加温后20%甘露醇注射液可减轻患者的痛苦,预防静脉损伤的发生。

OBJECTIVE:To investigate the clinical efficacy of intravenous dripping of heated 20% mannitol injection combined with before and after intravenous infusion of normal saline for preventing phlebitis.METHODS:A total of 120 patients who received intravenous dripping of heated 20% mannitol were randomly divided into observation group and control group.The patients in observation group were given intravenous dripping of 20% mannitol injection after heated to(35±1) ℃ combined with before and after intravenous infusion of normal saline.The patients in control group were given normal intravenous dripping of 20% mannitol injection at((14±5)℃).The changes of local blood vessels and tissue were observed in 2 groups.RESULTS:The incidence of subjective discomfort and phlebitis in observation group(13.33%) were remarkably lower than that in control group(63.33%)(P<0.01).CONCLUSION:Application of intravenous dripping of heated 20% mannitol combined with before and after intravenous infusion of normal saline can alleviate the pain of patients and prevent the occurrence of phlebitis.
