From the Guidelines

Post-surgical hematomas typically take 1 to 4 weeks to resolve completely, though this timeline varies based on the hematoma's size, location, and individual healing factors. The resolution time can be influenced by various factors, including the patient's overall health, the presence of any underlying medical conditions, and the effectiveness of post-operative care 1.

Factors Influencing Resolution Time

  • Size of the hematoma: Larger hematomas tend to take longer to resolve than smaller ones.
  • Location of the hematoma: Hematomas in areas with good blood supply and drainage may resolve faster than those in areas with poor circulation.
  • Individual healing factors: Patients with conditions that affect blood clotting or healing, such as diabetes or bleeding disorders, may experience delayed resolution of hematomas.

Management of Post-Surgical Hematomas

To promote healing and reduce the risk of complications, patients can follow these guidelines:

  • Apply cold compresses for 15-20 minutes several times daily during the first few days after surgery to reduce swelling and pain.
  • Switch to warm compresses after 48-72 hours to help the body absorb the collected blood more efficiently.
  • Use over-the-counter pain medications like acetaminophen (Tylenol) to manage discomfort, but avoid NSAIDs like ibuprofen or aspirin initially as they may increase bleeding risk.
  • Keep the affected area elevated when possible and follow the surgeon's specific activity restrictions to speed healing.

Monitoring for Complications

It is essential to monitor the hematoma for signs of infection or continued bleeding, such as:

  • Increasing pain
  • Redness
  • Warmth
  • Fever
  • Enlargement of the hematoma If any of these symptoms occur, patients should contact their healthcare provider promptly for further evaluation and treatment 1.

From the Research

Post-Surgical Haematomas

  • The time it takes for post-surgical haematomas to resolve can vary depending on several factors, including the size and location of the hematoma, as well as the individual patient's overall health 2.
  • A study on chronic subdural hematoma found that the median time to resolution was 161 days, with some patients taking several months to a year to fully recover 2.
  • The resolution time for post-surgical haematomas can be influenced by factors such as heavy drinking and advanced age, which can delay the resolution process 2.
  • There is limited research available on the specific topic of post-surgical haematomas, and more studies are needed to fully understand the factors that affect their resolution 3, 4, 5, 6.

Management of Post-Surgical Haematomas

  • The management of postoperative bleeding is crucial to prevent complications and promote healing 4, 5.
  • Identifying and correcting potential causes of coagulopathy both pre- and post-operatively can help reduce the risk of hemorrhage 5.
  • Adequate perioperative pain management is also important for patient care and outcomes, and can help reduce the risk of complications such as haematomas 3, 6.
  • A comprehensive approach to postoperative care, including preoperative planning, pain assessment, and pharmacological and non-pharmacological strategies, can help optimize patient outcomes 6.
