Abstract
BACKGROUND
Anesthetic drugs used in labor analgesia also paralyze the bladder muscle by blocking the sacral plexus, thereby affecting maternal postpartum spontaneous urination and increasing the risk of postpartum urinary retention (PUR).
AIM
To analyze the effect of percutaneous electrical stimulation at the Baliao point combined with biofeedback therapy for PUR prevention.
METHODS
We selected 182 pregnant women who received labor analgesia in obstetrics between June 2022 and December 2023. They were divided into the combined therapy group (transcutaneous electrical stimulation of the Baliao point combined with biofeedback therapy) and the control group (biofeedback therapy alone). The first spontaneous urination time, first postpartum urine volume, bladder residual urine volume, postpartum hemorrhage volume, pre-urination waiting time, PUR incidence, adverse reactions, and the intervention’s clinical efficacy were compared between the two groups.
RESULTS
The first spontaneous urination time after delivery was more delayed (2.92 ± 1.04 h vs 3.61 ± 1.13 h, P < 0.001), with fewer initial postpartum urine (163.54 ± 24.67 mL vs 143.72 ± 23.95 mL, P < 0.001), more residual bladder urine (54.81 ± 10.78 mL vs 65.25 ± 13.52 mL, P < 0.001), more postpartum bleeding (323.15 ± 46.95 mL vs 348.12 ± 45.03 mL, P = 0.001), and longer waiting time for urination (0.94 ± 0.31 min vs 1.29 ± 0.42 min, P < 0.001), in the control group than in the combined therapy group. The control group also had higher PUR incidence (4.65% vs 15.85%, P = 0.016). Both groups had no adverse reactions, but the clinical total efficacy rate of the intervention was significantly higher in the combined therapy group than in the control group (95.35% vs 84.15%, P = 0.016).
CONCLUSION
Percutaneous electrical stimulation of the Baliao point combined with biofeedback can significantly promote postpartum micturition of parturients with labor analgesia, thereby effectively preventing PUR occurrence.
Core Tip: Epidural anesthesia is mainly used for labor analgesia. However, the pain block of anesthetics on the sacral plexus greatly reduces the sensitivity of sphincter function and bladder detrusor function, easily causing dysuria or increase of bladder residual urine volume and promoting postpartum urinary retention (PUR) occurrence. Our research focuses on the effect of percutaneous electrical stimulation of the Baliao point combined with biofeedback therapy in promoting postpartum micturition among parturients with labor analgesia. This intervention is better than biofeedback therapy alone for parturients with labor analgesia because it is more effective in preventing PUR.
