Objective To observe the effect of Liuhe Pills combined with sitz bath in povidone iodine diluent for nursing of perianal infection in patients with hematologic malignancy.

Methods A total of 180 hematologic malignancy patients complicated with perianal infection in the Department of Hematology from January 2020 to December 2022 were selected as research objects. According to the order of hospital admission, they were divided into control group (n=90) and experimental group (n=90). The control group was treated with sitz bath in 1∶200 povidone iodine diluent on the basis of routine perianal cleaning care, while the experimental group was treated with external application of Liuhe Pills on the basis of the control group. The clinical efficacy, perianal pain score and perianal adverse reactions were compared between the two groups.

Results After intervention, the total effective rate of the experimental group was 95.56%, which was significantly higher than 83.33% of the control group (P < 0.01). There were significant differences in perianal pain scores between two groups at 2, 3, 7 and 14 days after intervention (P < 0.05 or P < 0.01). Patients in both groups did not have serious adverse reactions; the incidence of adverse reactions was 14.44% in the control group, which showed no significant difference when compared to 16.67% in the experimental group (P>0.05).

Conclusion Application of Liuhe Pills combined with sitz bath in povidone iodine diluent is effective in the nursing of perianal infection in patients with hematologic malignancy, which can alleviate the pain and promote the recovery.
