研究组 & 干预措施
Ultrasound Shear Wave Elastography Examination - Higher
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.
干预措施: Fentanyl Injection (Drug)
Ultrasound Shear Wave Elastography Examination - Mid
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.
干预措施: Fentanyl Injection (Drug)
Ultrasound Shear Wave Elastography Examination - Lower
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.
干预措施: Fentanyl Injection (Drug)
