RCT - Efficacy of Intravenous Vitamin C Versus Placebo on Estimated Blood Loss in Total Abdominal Hysterectomy
Enrolling by invitation · Not applicable · Has a placebo group
Conditions studied: Myoma;Uterus, Adenomyosis of Uterus
In brief
Intervention Group: Received two 1 gm doses of Vitamin C intravenously (IV). first Dose: At midnight on the day of surgery. Second Dose: Immediately after the surgical incision. Control Group: Received two doses of a normal saline intravenously (IV) at the exact same times. The primary outcome was to compare intraoperative blood loss between patients who received intravenous Vitamin C and those who did not, following an abdominal hysterectomy under general anesthesia. Intraoperative estimated blood loss (EBL) was meticulously quantified by weighing surgical gauze and measuring suction canister volumes. The secondary outcomes were to evaluate the potential benefits of Vitamin C administration, including: * Reduction in the decline of hematocrit levels after surgery. * Reduction of the length of hospital stay
