Is a computed tomography (CT) scan of the pelvis with and without contrast indicated for a post-cesarean section (C-section) patient experiencing severe pain?

From the Guidelines

No, a CT scan with and without contrast of the pelvis is not the first-line approach for evaluating severe pain in a post-C-section patient. Instead, start with a thorough clinical assessment including vital signs, abdominal examination, and evaluation of the surgical incision. Initial management should focus on optimizing pain control with a multimodal approach, such as scheduled NSAIDs (ibuprofen 600mg every 6 hours) combined with acetaminophen (1000mg every 6 hours) and opioids as needed (oxycodone 5-10mg every 4-6 hours) for breakthrough pain. If pain seems disproportionate to expected post-surgical course, consider potential complications like endometritis, wound infection, or hematoma. In these cases, laboratory tests (CBC, CRP) and ultrasound would typically be the initial imaging modality of choice due to lack of radiation exposure, as suggested by the American College of Radiology 1. CT with contrast would only be considered if there is strong suspicion of a serious complication not visible on ultrasound, such as deep abscess, bowel injury, or vascular complication. The risks of radiation exposure and contrast agents make CT less suitable as a first-line investigation in postpartum patients, particularly if they are breastfeeding.

Some key points to consider when evaluating the need for imaging in a post-C-section patient with severe pain include:

• Clinical assessment and pain management should be the initial focus
• Ultrasound is a suitable initial imaging modality due to its lack of radiation exposure
• CT with contrast may be considered in cases of suspected serious complications not visible on ultrasound
• The American College of Radiology suggests that CT abdomen and pelvis with IV contrast is usually appropriate for the initial imaging of acute pelvic pain, but this may not be the case in postpartum patients due to radiation exposure concerns 1.

It's essential to weigh the benefits and risks of imaging modalities in postpartum patients, prioritizing those that minimize radiation exposure and potential harm to the patient and their baby, especially if breastfeeding.

From the Research

Severe Pain Management after C-Section

• The management of severe pain after a C-section is crucial for the patient's recovery and well-being 2.
• Studies have shown that inadequate pain management can lead to persistent pain, increased opioid use, and delayed functional recovery 2, 3.
• Multimodal analgesia, including neuraxial morphine and nonopioid adjuncts, is recommended for optimal pain management after C-section 2.

Imaging Studies for Post-C-Section Pain

• There is no direct evidence to suggest that a CT scan with and without contrast of the pelvis is necessary for managing severe pain after a C-section.
• The provided studies focus on pain management, antibiotic prophylaxis, and persistent pain after C-section, but do not discuss the use of CT scans for postoperative pain evaluation 4, 5, 6, 2, 3.

Alternative Approaches

• A thorough clinical evaluation and assessment of the patient's symptoms and medical history are essential for determining the cause of severe pain after a C-section.
• Other diagnostic tools, such as ultrasound or MRI, may be considered if there is a suspicion of a specific complication or condition causing the pain.
• However, without further evidence, it is unclear whether a CT scan with and without contrast of the pelvis would be a necessary or appropriate diagnostic tool in this scenario.
