Intrauterine gauze packing for massive hemorrhage during cesarean section: analysis of 30 cases. Bleeding, uterine fundal height. Results showed that all 30 cases had the gauze removed within 24 hours postoperatively, not later than 36 hours. In preparation for blood transfusion and reducing intraoperative conditions, such as uterine massage and extraction indoors, the gauze was removed smoothly. Among the 2 patients with vaginal fornix intraocular tamponade, the yarn in the fornix was removed first, followed by the yarn in the uterine cavity. Postoperative complications: among the 30 cases, there were 8 cases of postoperative morbidity; body temperature returned to normal, and there were no cases of puerperal uterine hemorrhage. Discussion on major hemorrhage during cesarean section: traditional treatments include uterine massage, application of uterine contraction hormones, and uterine artery ligation, which, when ineffective, may necessitate a hysterectomy, often resulting in long operation times and more bleeding. In recent years, scientific research has proven that the uterus is not only a hormone target organ but also produces many bioactive substances and hormones, so we advocate conservative treatment of the uterus. The method of packing the uterine cavity with gauze for hemostasis is simple and quick. Hospital treatment of 30 cases was completely successful, with none of the patients requiring a hysterectomy. However, if conservative treatment is ineffective and life-threatening, one should seize the opportune moment to perform a life-saving hysterectomy.
