Research Status of Prenatal and Perinatal Influence Factors of Female Levator Ani Muscle Injury

doi:10.12280/gjfckx.20201111

Abstract

Abstract:

Levator ani muscle injury (LAMI), which is the most common muscle injury after vaginal delivery, has been considered as a risk factor and independent predictor of pelvic organ prolapse, and plays an important role in the occurrence and development of a variety of pelvic floor functional disorders. In recent years, although the understanding of the factors related to the prenatal and perinatal aspects of female LAMI is not completely clear, there is still some progress. Among them, vaginal delivery represented by forceps delivery and prolonged second stage of labor are widely considered to be the risk factors for LAMI. Cesarean section and epidural anesthesia had certain protective effects on LAMI. Gestational age and multiple deliveries were irrelevant of LAMI, but the understanding of the relationship between other factors and LAMI remains to be unified. It is of great significance to pay attention to the research status of influencing factors of LAMI in women before and during childbirth for reasonably estimating the risk of pelvic floor diseases and timely and effective obstetric intervention.
