Intraoperative blood salvage during Caesarean section significantly reduced homologous blood transfusions and hospital stays. This technique also led to higher hemoglobin levels in the initial postoperative days, improving patient recovery.

Area of Science:

  • Obstetrics and Gynecology
  • Transfusion Medicine
  • Surgical Techniques

Background:

  • Caesarean sections can involve significant blood loss, necessitating transfusions.
  • Autologous blood salvage offers a potential method to reduce reliance on allogeneic blood products.

Purpose of the Study:

  • To evaluate the efficacy and safety of intraoperative autologous blood salvage during Caesarean sections.
  • To compare outcomes between patients undergoing Caesarean section with and without intraoperative blood salvage.

Main Methods:

  • A randomized controlled trial involving 68 patients undergoing Caesarean section.
  • Intraoperative blood was collected, washed using a Dideco machine, and reinfused in the study group (n=34).
  • Blood was tested for contaminants, and specific guidelines were followed for salvage, including avoiding cord blood and eliminating the buffy coat.

Main Results:

  • The blood salvage group (Group 1) had significantly lower rates of homologous blood transfusions (2.9% vs 23.5%, P=0.01).
  • Patients in Group 1 experienced significantly shorter postoperative hospital stays (5.3 vs 7.3 days, P=0.003).
  • Hemoglobin concentrations were significantly higher in Group 1 during the first four days post-surgery compared to the control group.

Conclusions:

  • Intraoperative autologous blood salvage is an effective strategy to reduce homologous blood transfusions in Caesarean sections.
  • This method improves postoperative hemoglobin levels and shortens hospital stays, enhancing patient recovery.
  • Careful adherence to salvage protocols ensures the safety and efficacy of the procedure.
