IV vs Oral Acetaminophen for Spine Surgery Pain Management
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine whether intravenous (IV) acetaminophen manages pain after spine surgery more effectively than oral acetaminophen. By comparing these two forms, the researchers hope to reduce the need for opioids, which can cause serious side effects and significantly contribute to the opioid crisis. Suitable candidates for this trial include those diagnosed with lumbar spinal stenosis (narrowing of the spinal canal) who have not found success with other treatments. As a Phase 4 trial, this research seeks to understand how the already FDA-approved and effective treatment benefits a broader range of patients.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are taking more than 30mg/day of oral morphine sulfate or certain other medications like Isoniazid or barbiturates.
What is the safety track record for IV and oral acetaminophen?
Research has shown that both IV (intravenous) and oral acetaminophen are safe options for managing pain. IV acetaminophen can reduce the need for morphine after surgery, potentially lowering the risk of opioid-related side effects. One study highlighted its effectiveness as an alternative to opioids, reducing side effects like nausea and vomiting.
Oral acetaminophen is also recognized for its safety and is commonly used as a non-opioid pain reliever. It is generally well-tolerated by patients, similar to IV acetaminophen, making it a reliable option for pain management.
In summary, both IV and oral acetaminophen are considered safe for pain management. They are well-tolerated and have a low risk of serious side effects, making them suitable for those considering participation in clinical trials.12345Why are researchers enthusiastic about this study treatment?
Researchers are excited about comparing intravenous (IV) and oral acetaminophen for managing pain after spine surgery because each method offers unique benefits. IV acetaminophen delivers the medication directly into the bloodstream, potentially providing faster pain relief compared to oral options, which have to pass through the digestive system first. On the other hand, oral acetaminophen is more convenient and easier to administer outside of a hospital setting, making it a practical choice for ongoing pain management after surgery. This trial aims to determine which method offers the best balance of effectiveness and convenience, potentially improving recovery experiences for patients undergoing spine surgery.
What evidence suggests that this trial's treatments could be effective for spine surgery pain management?
This trial will compare the effectiveness of intravenous (IV) acetaminophen with oral acetaminophen for managing pain after spine surgery. Studies have shown that IV acetaminophen can effectively manage pain and reduce the need for opioids post-surgery. Research indicates that IV acetaminophen works faster than the pill form, which is crucial immediately after surgery. Although IV acetaminophen is usually more expensive, it is considered a safe and effective option and may lower the risk of opioid-related side effects. Conversely, oral acetaminophen can provide similar pain relief after surgeries like joint replacements. It can be effective when combined with other pain medications, helping to reduce opioid use. Both forms of acetaminophen offer benefits, and the choice may depend on factors like cost and the patient's condition after surgery.14678

Interventions
- IV vs Oral Acetaminophen
- Multimodal Analgesic Approach
- Ofirmev
- Per Os Acetaminophen
Trial Overview
The trial is testing whether IV acetaminophen (Ofirmev) can improve pain management after lumbar spinal surgery compared to oral acetaminophen while reducing opioid usage and complications. The goal is to see if IV administration during perioperative care offers better outcomes in terms of pain control and fewer side effects from opioids.

Treatment groups
Active Control
Preop: Eligible patients will receive IV acetaminophen within 3 hours of OR start time. Postop: Eligible patients will be administered IV acetaminophen following 1 and 2 level LLIFs supplemented with instrumented posterior fusion to evaluate pain management outcomes. Dosing for the group will be the following: • IV Acetaminophen 1,000 mg \[100 ml\] every 6 hours for 48 hours postoperative. Medication will be given at least 6 hours following initial preoperative dose of IV acetaminophen. Postop supplemental pain medications: All patients will receive a standardized hydromorphone IV-PCA order set for 24 hours postoperatively. The use of tramadol and tapentadol will specifically be discouraged due to challenges in determining morphine-equivalent dosing with these specific agents. Similarly, acetaminophen containing combination products (e.g. oxycodone/acetaminophen or hydrocodone/acetaminophen) will not be allowed due to overlap with the primary study medications.
