Abstract:

Safe, effective and controllable labor analgesia has been the goal pursued by anesthesiologists and obstetricians. Intraspinal labor analgesia is the first choice for labor analgesia, which improves the quality of labor by reducing labor pain while ensuring the safety of mother and infants. Pelvic floor dysfunction (PFD) associated with labor dysfunction is one of the common postpartum diseases, mainly including stress urinary incontinence, obstetrical anal sphincter injuries, female sexual dysfunction, etc. The effect of intraspinal labor analgesia on the pelvic floor function of primipara has always been the focus of attention and research by many clinical and scientific researchers. Intraspinal labor analgesia has a protective effect on the pelvic floor muscle and anal sphincter, does not affect the electrophysiological function of pelvic floor muscle, can reduce the incidence of postpartum stress urinary incontinence, and has no adverse effect on the sexual function of parturient. To summarize the effects of intraspinal labor analgesia on the pelvic floor function of primipara, so as to provide more clinical basis for the further popularization of intraspinal labor analgesia and the prevention and treatment of PFD in primipara.
