Evaluation of the efficacy and safety of intradermal needle therapy on the sleep quality of patients following laparoscopic hysterectomy: study protocol for a randomized controlled trial.

Background: Sleep disorder is a commonly reported complication in patients who have undergone a hysterectomy, which increases perioperative complications and delays patient recovery. Several pharmacological and non-pharmacological approaches have been employed to improve the quality of sleep of patients during the postoperative period, but these strategies have certain limitations. Intradermal needle therapy is now among the most common treatments for insomnia in traditional Chinese medicine (TCM).
