Objective: This study was designed to assess the effects of preventive nursing care combined with auricular acupressure on the incidence of postpartum urinary retention in women with vaginal delivery. Methods: A total of 260 women who delivered vaginally in Shijiazhuang Fourth Hospital from March 2019 to March 2020 were enrolled into the observation group and the control group, with 130 cases in each group. Both groups were given preventive nursing, and the observation group was given additional auricular acupressure. The incidence of urinary retention, duration of voiding, residual urine volume, and indwelling urinary catheter were analyzed, and the treatment efficiency and satisfaction towards nursing care were compared. Results: The observation group showed a significantly lower incidence of urinary retention and experienced a significantly earlier time to first urination than the control group (both P<0.001). The amount of residual urine at 6h and 24h after delivery in the observation group was significantly less than in the control group (P<0.05).Fewer cases of indwelling urinary catheters were found in the observation group than those in the control group (P<0.05). The treatment efficiency and nursing satisfaction in the observation group were both significantly better than those in the control group (P<0.05). Conclusion: The combination of preventive nursing with auricular acupressure can contribute to a higher satisfaction among parturients by alleviating postpartum urinary retention, shortening the time to first voiding, reducing residual urine volume, and avoiding indwelling urinary catheters, so it merits clinical promotion.

In recent years, due to the combined effects of individual behavior, psychological factors, environmental exposure, medical conditions, biological factors, etc., the incidence of preterm birth has gradually increased, so the incidence of various complications of preterm infants has also become higher and higher. This article is aimed at studying the therapeutic effects of preterm infants and proposing the application of rSO2 and PI image monitoring based on deep learning to the treatment of preterm infants. This article introduces deep learning, blood perfusion index, preterm infants, and other related content in detail and conducts experiments on the treatment of rSO2 and PI monitoring images based on deep learning in preterm infants. The experimental results show that the rSO2 and PI monitoring images based on deep learning can provide great help for the treatment of preterm infants and greatly improve the treatment efficiency of preterm infants by at least 15%.
