Effect of external application of Chinese medicine liquid on preventing phlebitis caused by intravenous indwelling needle: a retrospective study.

Object: To analyze the clinical effect of external application of self-made Chinese medicine liquid to prevent phlebitis caused by intravenous indwelling needle in our hospital.

Methods: According to different nursing strategies, 600 patients were divided into control group and observation group. The observation group received external application of self-made Chinese medicine liquid in our hospital; the control group was treated with wet compress with 50% magnesium sulfate solution. Then the success rate of indwelling needle puncture, the incidence of phlebitis, the incidence of pain during intravenous drip and the patients' satisfaction with the effect of phlebitis prevention and treatment were compared between the two groups. Then, the success rate of indwelling needle puncture, the incidence of phlebitis, the incidence of pain during intravenous drip and the patients' satisfaction with the effect of phlebitis prevention and treatment were compared between the two groups.

Results: The success rate of one-time puncture was 93.33% in the observation group and 81.67% in the control group. Observation group average indwelling catheter time for (3.89±2.37) days, significantly higher than that of control group (3.00±1.82) days; the incidence of phlebitis in the observation group was 27.33%, lower than that in the control group (43.00%). The satisfaction rate of observation group was 94.00%, significantly higher than that of control group (80.00%). All the differences were statistically significant (P<0.05).

Conclusion: Compared with magnesium sulfate wet compress, external application of self-made Chinese medicine liquid in our hospital can effectively prevent the occurrence of phlebitis caused by indwelling needle, especially relieve pain during intravenous drip in patients, with high patient satisfaction.
