To explore the clinical effect of salt-hot compress based on the theory of"Maiweiji" on mechanical phlebitis after PICC catheterization.

According to random number table, 202 patients after PICC catheterization were divided into the control group including 100 cases and the experimental group including 102 cases. The study were divided into the prevention stage and the treatment stage. In the prevention stage, the control group were given routine nursing while the experimental group were received routine nursing plus salt-hot compress. In the treatment stage, all the patients in mechanical phlebitis after the prevention stage were randomly divided into the group of salt-hot and the group of wet-hot by lottery, meanwhile, the group of salt-hot were given salt-hot compress, the group of wet-hot were received wet-hot compress.

In the prevention stage, the mechanical phlebitis rate of the experimental group was 8.82% (9/102), and it was 21% (21/100) in the control group, the difference had statistically significant (Z=-2.28, P < 0.05). In the treatment stage, the cure rate in 3 days and 7 days of the Group of Wet-hot were 5/15 and 10/15, and were 9/15 and 6/15 in the Group of Salt-hot, the average treatment time were (3.71±1.82) d and (4.31±1.58) d respectively, but the difference had no statistically significant(P > 0.05).

Salt-hot compress has the positive effect of preventing mechanical phlebitis. Besides, the therapeutic effect on mechanical phlebitis between the group of salt-hot and the group of wet-hot is about the same. Because of the simple operation, bargain price, being not contaminated clothing, salt-hot compress is more advantage.
