Abstract：Objective To investigate the analgesic effect of compound lidocaine cream in lymphocyte immunotherapy for women with recurrent spontaneous abortion (RSA). Methods A non-randomized controlled crossover design was adopted including 110 patients with RSA who were receiving lymphocyte immunotherapy. There were two groups in this study. 30 patients, who were in group 1, used compound lidocaine cream in the first two cycles (test group). And they used placebo cream in the next two cycles (control group). The group 2 contained 80 patients. They used placebo cream in the first two cycles (control group) and compound lidocaine cream in the next two cycles (test group). After 1 hour, intradermal injection was conducted. We used numerical rating scale (NRS), Faces pain scale (Wong-Banker score) and behavioral assessment scale to assess the degree of pain. Results For test group, the mean of NRS score, Wong-Banker score and behavioral assessment scale were 5.22±0.14, 5.23±0.14 and 3.98±0.13, which were lower than the corresponding scores in the control group. For the latter, the mean of NRS score, Wong-Banker score and behavioral assessment scale were 5.78±0.14, 5.85±0.15 and 4.78±0.15. For the three assessment methods, the differences of them were statistically significant (P<0.001). However, the effects of compound lidocaine cream or placebo cream in different treatment cycles showed no significant difference (P>0.05). Conclusion For women with recurrent spontaneous abortion, compound lidocaine cream can relieve pain in the treatment of lymphocyte immunotherapy and it is worthy to be popularized in clinical practice.
