ABSTRACT
Postpartum hemorrhage remains a major cause of maternal mortality and morbidity worldwide with higher rates found in resource-challenged countries. Conventional use of uterotonics such as oxytocin, prostaglandins, and medications to support coagulation, such as fibrinogen and tranexamic acid, are helpful but may not be sufficient to arrest life-threatening postpartum hemorrhage. Severe postpartum hemorrhage leads to an increased need for blood transfusions and the use of invasive techniques, such as intrauterine balloon tamponade, compression sutures, and arterial ligation, as advanced steps in the management cascade. In extreme cases where hemorrhage is resistant to these therapies, a hysterectomy may be necessary to avoid possible maternal death. Uterine packing with a chitosan-covered tamponade is an emerging tool in the armamentarium of the obstetrical team, especially when resources for advance surgical and other invasive options may be limited. Modified chitosan-impregnated gauze was originally described in the management of acute hemorrhage in the field of military medicine, combining the physiological antihemorrhaging effect of modified chitosan with a compression tamponade for the acute treatment of wound bleeding. The first described use in obstetrics was in 2012, showing that the chitosan-covered tamponade is an effective intervention to arrest ongoing therapy-resistant postpartum hemorrhage. Further studies showed a reduction in hysterectomies and blood transfusions. The method is, however, underreported and is not yet an established method used worldwide. To demonstrate the step-by-step application of the intrauterine chitosan-covered tamponade in the management of therapy-resistant postpartum hemorrhage, we have produced a teaching video to illustrate the important steps and techniques to optimize the effectiveness and safety of this novel intervention.
