〔Abstract〕 Objective To explore the effect of combining traditional Chinese medicine package with postpartum rehabilitation therapy device to reducing postpartum urinary retention. Methods 400 parturients admitted to the Sixth Affiliated Hospital of Guangzhou Medical University (Qingyuan People's Hospital) from August 1, 2018 to December 31, 2020 were randomly divided into observation group and control group, with 200 cases each according to the number table method. The observation group was treated with traditional Chinese medicine package combined with postpartum rehabilitation therapy device after delivery. The control group only received postpartum rehabilitation therapy after delivery. The time to urinate for the first time, the incidence of postpartum urinary retention, the rate of indwelling urinary catheter, and the incidence of postpartum hemorrhage were compared between the two groups. Results The first urination time of parturients in the observation group was (3.27 ± 0.98) h, which was shorter than (4.19 ± 1.08) h in the control group, and the difference was statistically significant (P < 0.05). The incidence of indwelling urinary catheter and postpartum urinary retention in the observation group was lower than that in the control group, the difference was statistically significant (P < 0.05); the incidence of postpartum hemorrhage in the observation group was 9 cases (4.5%) lower than that of the control group 21 cases (10.5 %), and the postpartum hemorrhage of the observation group was (368 ± 98) mL less than that of the control group (395 ± 121) mL, the difference was statistically significant (P < 0.05). Conclusion The combination of traditional Chinese medicine package and postpartum rehabilitation therapy instrument can effectively reduce the incidence of postpartum urinary retention, reduce the rate of postpartum indwelling urinary catheter due to urinary retention. It can increase the comfort of the puerpera, is easy to implement, and is easy for the puerpera to accept.
