Section One. Emergency Peripartum Hysterectomy As Postpartum Hemorrhage Treatment: Incidence, Risk Factors, And Complications Section Two. Millimeter Wave Therapy For Abdominal Incision Wound-A Clinical Study

Objective: The aim of the research was to investigate incidence, riskfactors, and complications associated with emergency peripartumhysterectomy (EPH), the ultimate treatment method for intractablepostpartum hemorrhage (PPH).Methods: This is a single center case-control study conducted inChongqing city in central China from1stJanuary2007–31stDecember2012for EPH performed as a treatment of postpartum hemorrhage (PPH) both incaesarean and vaginal delivery cases. While the study group included EPH(n=61) due to intractable PPH, the control group included no hysterectomy(n=333) during the same study period.Results: We found61cases recorded for EPH for intractable PPH.Incidence of peripartum hysterectomy was2.2per1000deliveries. EPH astreatment of intractable PPH include the followings:(i) blood loss1000-2000ml, crude odd ratio (OR)=18.48(95%CI5.1-65.7), adjusted oddratio (AOR)=9.1(95%CI2.2-37.7);(ii) blood loss>2000ml, OR=152 (95%CI43.7-528.4), AOR=45.3(95%CI11.6-176.9);(iii) previouscaesarean section, OR=5.5(95%CI2.9-9.7), AOR=3.7(95%CI1.4-9.9);(iv) uterine atony, OR=11.9(95%CI5.8-24.6), AOR=7.5(95%CI1.8-30.2);(v) placenta previa, OR=2.04(95%CI1.1-3.5), AOR=none.Conclusions: EPH is the last resort as treatment of intractable severepostpartum hemorrhage. Our study depicts that severe post partumhemorrhage, further dreaded complex events for EPH, has significantassociation with placental factors, previous caesarean section, and uterineatony. Pathologically, placenta accreta remained the most leading cause ofhysterectomy.
