What is the purpose of this trial?

This trial tests whether magnesium sulfate, administered through an IV, can help control pain for trauma patients in the Intensive Care Unit. Magnesium may reduce the need for narcotic pain relievers, providing a non-narcotic option for pain management. The trial compares the effects of magnesium sulfate to a saline solution to determine which is more effective. It seeks trauma patients in the ICU who are part of a hospital pain management plan and can provide consent. As a Phase 4 trial, this research aims to understand how an already FDA-approved and effective treatment can benefit more patients.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, if you regularly use opioids or are receiving continuous opioid infusions, you may not be eligible to participate.

What is the safety track record for magnesium sulfate?

Research has shown that magnesium sulfate is generally safe and effective for managing pain. It has reduced pain before and after surgeries, suggesting it might also benefit ICU patients with injuries.

Hospitals already use magnesium sulfate to treat low magnesium levels, so its safety is well-established. However, like any treatment, it can have side effects. Some reports mention slight harm if inhaled or if it contacts the skin, but this is uncommon in medical use.

Overall, healthcare has used magnesium sulfate for many purposes, and safety data supports its use. This trial aims to determine if it is a good option for managing pain in trauma patients. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Unlike the standard pain management options for trauma, which often rely on opioids, magnesium sulfate offers a different approach by acting as a calcium antagonist and NMDA receptor blocker. This means it can potentially reduce pain and inflammation without the risk of addiction and side effects associated with opioids. Researchers are excited about magnesium sulfate because it might not only offer effective pain control but also do so with fewer side effects, providing a safer alternative for managing trauma pain.

What evidence suggests that magnesium sulfate is effective for trauma pain management?

Studies have shown that magnesium sulfate effectively manages pain, especially post-surgery. Research indicates it reduces the need for narcotics, which are strong pain relievers. This reduction is important because fewer narcotics lead to fewer side effects for patients. Evidence suggests magnesium works by blocking certain pain signals in the body. In this trial, participants in the Magnesium Group will receive magnesium infusions. Previous studies reported that patients receiving magnesium infusions experienced less pain and fewer complications. This makes magnesium sulfate a promising option for controlling pain in trauma patients in the ICU. ^{5 6 7 8 9}

Are You a Good Fit for This Trial?

This trial is for adult trauma patients (18-99 years old) in the ICU who can consent to participate and are on a hospital-approved pain management plan. It's not for those with severe head injuries, heart failure, renal failure, alcohol withdrawal, expected anesthesia within 24-48 hours post-admission, unable to report pain, pregnant women, prisoners or regular opioid users.

What Are the Treatments Tested in This Trial?

Interventions

• Magnesium Sulfate
• Normal saline placebo

Trial Overview

The study tests if intravenous magnesium sulfate can better manage pain in critically ill trauma patients compared to a saline placebo. The goal is to see if magnesium reduces the need for narcotics and offers an alternative non-narcotic pain control method.

How Is the Trial Designed?

Group I: Magnesium Group Experimental Treatment 1 Intervention

The magnesium group arm will receive a 40 mg/kg IBW (maximum 4 g) bolus of intravenous magnesium sulfate, followed by a continuous infusion of 0.5 g/hr for a total of 24 hours.

Group II: Control Group Placebo Group 1 Intervention

The control arm will receive the same volume and rate of saline as if they were in the experimental group.

In a study involving 40 men undergoing prostate surgery, the use of magnesium sulfate (MgSO4) for wound infiltration significantly reduced the need for tramadol, a pain medication, compared to intravenous MgSO4 administration.

Both methods of MgSO4 delivery resulted in similar pain scores, indicating effective pain management without any observed side effects from either route of administration.

In a study of 218 patients undergoing elective coronary artery bypass graft (CABG) surgery, intravenous magnesium sulfate (MgSO4) infusion significantly reduced post-operative pain scores and led to quicker extubation compared to a placebo.

Patients receiving MgSO4 reported lower pain levels at multiple time points (6, 12, 18, and 24 hours post-surgery) and required less morphine for pain management, indicating its efficacy in enhancing post-operative recovery.
