What is the purpose of this trial?

This trial examines how different doses of the painkiller fentanyl affect the diaphragm muscle, which aids in breathing. The researchers aim to determine if varying doses of fentanyl alter diaphragm performance during breathing tasks. Participants will receive different doses of fentanyl as part of their surgical care, and a special ultrasound will assess their diaphragm function. Individuals undergoing lower leg or hip surgeries at specific hospitals, who do not have lung issues like asthma, might be suitable for this trial. As a Phase 4 trial, this research seeks to understand how this FDA-approved and effective treatment can benefit more patients.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What is the safety track record for Fentanyl Injection?

Research shows that fentanyl, the treatment in this study, affects breathing by acting on the brain's breathing centers, especially at higher doses. However, studies have found that low doses used during procedures like spinal anesthesia do not clearly establish a risk of serious breathing problems.

As this study is in Phase 4, fentanyl has already received approval for use in other situations, indicating that its safety is fairly well understood. Nonetheless, caution remains important because fentanyl can cause serious side effects, such as breathing issues. Participants should be aware of these risks and discuss any concerns with the study team. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Researchers are excited about this trial because it explores how different doses of opioids, specifically fentanyl, affect respiratory function during surgery using a technique called ultrasound shear wave elastography. This method allows doctors to visualize how tissues respond to opioids by measuring their stiffness, which could lead to better understanding and management of respiratory complications. Unlike traditional methods that might rely on indirect or invasive measurements, this approach provides real-time, non-invasive insights into how breathing techniques can mitigate these complications. Ultimately, the findings could improve safety and outcomes for patients undergoing surgeries requiring opioid administration.

What evidence suggests that this trial's treatments could be effective for respiratory complications?

Research has shown that fentanyl effectively reduces pain, particularly after surgery. Studies have found that it significantly lessens the need for other pain medications and improves overall pain management. However, fentanyl can also slow breathing, posing a danger at higher doses. This trial will examine the effects of different fentanyl doses on respiratory function. Participants will receive low, mid, or high doses of opioids during elective lower extremity orthopedic surgery and will undergo ultrasound shear wave elastography examinations while performing various breathing techniques. Understanding these effects is crucial when considering fentanyl for pain and breathing issues. ^{3 6 7 8 9}

In a study of 16 asthmatic children aged 5-14 years, QVAR inhalation resulted in significantly higher lung deposition of the medication compared to other aerosol delivery systems, with lung deposition rates reaching up to 54.1% in older children.

The study found that lung deposition of QVAR positively correlated with lung function measures (FEV1 and FVC), while gastrointestinal deposition negatively correlated with these measures, indicating that effective lung delivery is crucial for therapeutic efficacy.

The FDA has approved a new nasal spray formulation of fentanyl, called Lazanda-Archimedes, specifically for managing breakthrough pain in adult cancer patients who are already tolerant to opioid therapy.

This approval adds to the existing forms of fentanyl available in the US, which include intravenous, intrathecal, epidural, transdermal, and oral transmucosal options, providing more flexibility in pain management for patients.

In a study involving 30 cancer patients, a high dose of fentanyl sublingual spray (FSS) significantly reduced exertional dyspnea and increased walking distance compared to baseline, indicating its efficacy in managing breathlessness.

The low dose of FSS showed a nonsignificant reduction in dyspnea but still improved walking distance, suggesting that while both doses are tolerated, the high dose may provide better symptom relief.

Ciclesonide administered as an HFA nasal aerosol (CIC-HFA) and as an aqueous nasal spray (CIC-AQ) resulted in significantly lower systemic exposure of its active metabolite, desisobutyryl ciclesonide, compared to the HFA metered dose inhaler (CIC HFA-MDI), with CIC-HFA showing 10-fold lower and CIC-AQ at least 40-fold lower exposure.

All formulations of ciclesonide were well tolerated by participants, with mild adverse events occurring in only 30% of the 30 volunteers, indicating a favorable safety profile for this treatment.

The exhalation delivery system Xhance® delivers fluticasone propionate more effectively to the nasal cavity compared to conventional nasal sprays like Flonase®, resulting in higher systemic exposure with lower risk of drug loss through drip-out or swallowing.

In a study involving 90 healthy subjects and 30 asthma patients, Xhance® showed significantly higher peak drug levels (Cmax) than Flonase® at similar doses, indicating its potential for improved efficacy, while still maintaining low systemic exposure compared to inhalational aerosols like Flovent® HFA.

The 12 microg/h fentanyl transdermal patch was effective in treating moderate to severe pain over a 28-day trial with 227 patients, showing significant improvement in pain levels and overall therapy assessments.

In a study of 504 advanced cancer patients, those using transdermal fentanyl reported higher overall satisfaction with their pain management compared to those using sustained-release oral morphine.

Patients on transdermal fentanyl experienced significantly fewer and less impactful side effects from their pain medication, which may contribute to their greater satisfaction, despite being older and having lower functioning and well-being scores.
