Abstract:Objective The purpose of this study is to find the clinical characteristics of epidural morphine-induced pruritus (EMIP) in Tibetan parturients based on the clinical observation Methods This is a prospective single-center clinical observational study. Follow-up evaluation was performed at 3, 6, 12, 24 and 48 hours after morphine administration. The primary outcome was the incidence of EMIP. In addition, the occurrence, duration and location of pruritus were recorded. Results A total of 17 subjects were selected and all completed the clinical observation. Two of them had EMIP. The main symptoms of EMIP patients were pruritus on the head, face, chest and abdomen. The pruritus symptoms emerged at 16 and 2 hours after morphine administration, lasting 24 and 3 hours, respectively. Conclusion This study found that the incidence of EMIP among parturients in Tibet was 11.8%. The clinical characteristics of EMIP were generally consistent with those reported in the literature. The possible risk factors of EMIP among Tibetan parturients need to be further explored by accumulating more data.
