What strategies can be used to minimize bleeding risk after an anal exam under anesthesia?

From the Guidelines

To minimize bleeding risk after an anal exam under anesthesia, the use of tranexamic acid is recommended, as it has been shown to reduce blood loss and the need for transfusion 1. Several strategies can be implemented to minimize bleeding risk after an anal exam under anesthesia.

• Apply direct pressure to the anal area for 5-10 minutes immediately after the procedure using sterile gauze.
• Patients should be prescribed stool softeners such as docusate sodium (100 mg twice daily) for 7-10 days to prevent straining during bowel movements, which can disrupt healing and trigger bleeding.
• Sitz baths with warm water for 10-15 minutes, 2-3 times daily, help reduce inflammation and promote healing.
• Patients should avoid strenuous activities, heavy lifting (anything over 10 pounds), and prolonged sitting for at least 48-72 hours post-procedure.
• If biopsies were taken, topical hemostatic agents like Surgicel or silver nitrate may be applied during the procedure.
• For patients on anticoagulants or antiplatelet medications, these should be managed in consultation with the prescribing physician, potentially temporarily adjusting dosages based on individual risk factors, as the management of anticoagulants in the peri-operative period should balance the risk of bleeding with the risk of thrombosis 1.
• Adequate hydration and a high-fiber diet help maintain soft stools and reduce straining. The use of cell salvage and anti-fibrinolytics, such as tranexamic acid, is recommended in all patients who are bleeding, where blood loss >500 ml (> 8 ml.kg-1 in children weighing >10 kg) is possible and/or in patients are unable to receive donor blood 1. Minimizing iatrogenic anaemia by managing blood sampling appropriately is also crucial 1. It is essential to note that the procedure can be safely done under full dose anticoagulation, and consideration should be given to holding the dose of direct oral anticoagulants (DOACs) on the day of the procedure to avoid peak anticoagulant effects 1. Procedures or surgeries can be divided into a two‐tier risk scheme for bleeding, including high risk and low risk, and the classification of “low bleed risk” or “non‐high bleed risk” procedures or surgeries was less specific and included various invasive procedures and same‐day office procedures 1. For minor procedures, such as dental extractions, clinical data support the continuation of vitamin K antagonists (VKAs) and the use of a prohemostatic agent, such as oral tranexamic acid mouthwash with local application and expectoration, or partial interruption of VKA therapy 2-3 days before the procedure 1.

Strategies to Minimize Bleeding Risk

To minimize bleeding risk after an anal exam under anesthesia, several strategies can be employed:

• The use of regional anesthesia, such as spinal anesthesia, caudal blockade, posterior perineal blockade, and local anesthesia, can help reduce bleeding risk by providing selective segmental block and potentiated analgesia 2.
• The administration of antifibrinolytic agents, such as tranexamic acid (TXA) and epsilon-aminocaproic acid (EACA), has been shown to reduce postoperative bleeding in various surgical procedures, including cardiopulmonary bypass and open rhinoplasty 3, 4.
• The use of FDA-approved hemostatic drugs, such as aprotinin, desmopressin, TXA, and EACA, may also be considered, although their efficacy in reducing bleeding risk is still being studied 5.

Bleeding Risk Factors

Several factors can contribute to bleeding risk after an anal exam under anesthesia, including:

• The type of anesthesia used, with general anesthesia potentially carrying a higher risk of bleeding than regional anesthesia 2.
• The presence of underlying medical conditions, such as coagulopathy or bleeding disorders, which can increase the risk of bleeding 5.
• The use of certain medications, such as anticoagulants or antiplatelet agents, which can increase the risk of bleeding 4.

Postoperative Care

To minimize bleeding risk after an anal exam under anesthesia, proper postoperative care is essential:

• Monitoring of vital signs and bleeding parameters, such as blood loss and hemoglobin levels, can help identify potential bleeding complications early 2.
• The use of autotransfusion techniques, such as mediastinal and pleural tube drainage, can help reduce blood loss and minimize the need for blood transfusions 4.
• The administration of analgesics and other medications, as needed, can help manage postoperative pain and discomfort, which can contribute to bleeding risk 2.
