Summary

This trial tests how opioids affect the strength of the diaphragm muscle, which helps with breathing.

Who is the study for?
This trial is for adult men and women who are having lower limb orthopedic surgery at St. Mary Hospital or Rochester Methodist within the Mayo Clinic in Rochester. It's not for those with lung conditions like COPD or asthma, anyone who doesn't want to participate in research, or pregnant individuals.
What is being tested?
The study is looking into how different doses of an opioid called Fentanyl affect the diaphragm muscle's ability to work harder and generate force during breathing, especially after surgery.
What are the potential side effects?
While not explicitly listed, common side effects of Fentanyl can include drowsiness, nausea, confusion, constipation, sedation, respiratory depression (slowed breathing), and potential dependency.

Trial Design

3Treatment groups
Experimental Treatment
Group I: Ultrasound Shear Wave Elastography Examination - MidExperimental Treatment1 Intervention
Subjects identified as being administered mid dose opioids during an elective lower extremity orthopedic surgery per standard of care will undergo an ultrasound shear wave elastography examination while performing different breathing techniques.
Group II: Ultrasound Shear Wave Elastography Examination - LowerExperimental Treatment1 Intervention
Subjects identified as being administered low dose opioids during an elective lower extremity orthopedic surgery per standard of care will undergo an ultrasound shear wave elastography examination while performing different breathing techniques.
Group III: Ultrasound Shear Wave Elastography Examination - HigherExperimental Treatment1 Intervention
Subjects identified as being administered higher dose opioids during an elective lower extremity orthopedic surgery per standard of care will undergo an ultrasound shear wave elastography examination while performing different breathing techniques.
