What blood conservation techniques are recommended for an adult female with potential gynecological issues undergoing total hysterectomy?

Blood Conservation Techniques for Total Hysterectomy

For an adult female undergoing total hysterectomy, implement a comprehensive patient blood management strategy centered on three pillars: preoperative anemia detection and treatment, intraoperative blood loss reduction through pharmacologic agents and cell salvage, and optimization of physiological tolerance to anemia. 1

Preoperative Optimization

Anemia Screening and Treatment

• Check hemoglobin levels on all patients before listing for surgery and investigate any woman with Hb <120 g/L, as preoperative anemia occurs in up to one-third of surgical patients and correlates with worse outcomes 1
• Treat the underlying cause of anemia appropriately and delay elective surgery if necessary to allow time for correction through established pre-assessment clinic pathways 1

Intraoperative Blood Conservation

Pharmacologic Hemostatic Agents

Tranexamic Acid (TXA)

• Administer prophylactic tranexamic acid 1 g intravenously at the start of surgery, as this reduces total blood loss from 134.8 mL to 98.4 mL (subjective estimate) and from 166.0 mL to 100.0 mL (objective measurement) 2
• TXA significantly decreases the incidence of blood loss ≥500 mL (from 12.7% to 3.6%) and reduces reoperations for postoperative hemorrhage (from 5.4% to 1.2%), with a number needed to treat of 24 2
• Topical application of 1.5 g TXA in 100 mL normal saline over the raw pelvic surface before peritoneal closure is equally effective as intravenous administration, providing flexibility in administration route 3
• No thromboembolic events or deaths have been reported with prophylactic TXA use in benign hysterectomy 2

Vasopressin

• Consider vasopressin injection into the surgical field, which reduces estimated blood loss by approximately 120 mL compared to normal saline, though this does not translate to differences in transfusion rates or other clinically significant outcomes 4
• Vasopressin demonstrates safety without increased rates of febrile morbidity or pelvic infection 4

Cell Salvage

• Implement cell salvage for cases where blood loss >500 mL is anticipated, as recommended for high- or medium-risk non-obstetric surgery 1
• If the patient has known or suspected malignancy, a leucocyte filter must be used to reduce theoretical risk of tumor cell reinfusion 1
• Bacterial contamination of the surgical field remains an absolute contraindication to cell salvage 1
• Cell salvage may be continued postoperatively if ongoing blood loss occurs 1

Surgical Technique Considerations

Route Selection and Blood Loss

• Recognize that median estimated blood loss varies by surgical approach: 238-660.5 mL for abdominal hysterectomy, 156-568 mL for laparoscopic hysterectomy, and 215-287 mL for vaginal hysterectomy 5
• Transfusion is more likely after laparoscopic compared to vaginal hysterectomy (odds ratio 2.07) 5
• Optimize surgical technique to minimize the 10.5% infectious complication rate for abdominal hysterectomy and reduce bleeding complications, which represent the most common cause of perioperative morbidity 5, 1

Transfusion Management

Restrictive Transfusion Protocols

• Adopt restrictive transfusion protocols based on current evidence, as patient blood management has been recommended as a standard of care in the UK National Health Service 1
• Obtain informed consent for potential blood transfusion preoperatively and document this discussion in the medical record 1

Transfusion Safety Procedures

• Ensure all staff involved in blood component administration are trained and competency-assessed per local policy 1
• Perform bedside identity checks using four core identifiers (first name, last name, date of birth, patient identification number) immediately before transfusion to prevent ABO incompatibility, the most serious transfusion error 1
• Complete red cell transfusions within 4 hours of removal from the blood fridge 1
• Maintain 100% traceability of all blood components as legally required 1

Postoperative Considerations

Antibiotic Re-dosing

• Re-dose prophylactic antibiotics if blood loss exceeds 1,500 mL, as recommended for obstetric hemorrhage management (applicable principle for major gynecologic surgery) 6

Patient Notification

• Inform patients before hospital discharge if they received blood or blood components, as they will otherwise be unaware and need to know they are removed from the donor pool 1
• Notify the patient's general practitioner of any blood product administration 1

Common Pitfalls to Avoid

• Do not delay elective surgery for minor anemia without investigation and treatment, as this represents a missed opportunity for optimization 1
• Do not omit leucocyte filters when using cell salvage in patients with known or suspected malignancy, as this is a critical safety requirement 1
• Do not skip preoperative hemoglobin screening, as one-third of patients may have unrecognized anemia that worsens surgical outcomes 1
• Do not withhold tranexamic acid based on unfounded thrombosis concerns in this population, as no thromboembolic events occurred in randomized trials of benign hysterectomy 2
