Quality of Recovery after opioid-free vs opioid-based general anesthesia in major urological surgery
This trial tests whether opioid-free anesthesia leads to a better recovery score, as measured by QoR-15, in adults undergoing major urological surgery compared to anesthesia with remifentanil.
-
Improving pain control for children on breathing machines
This trial tests whether giving IV acetaminophen and/or IV ketorolac can reduce pain and the need for opioids in children aged 2 months to 17½ years who are on mechanical ventilation for acute respiratory failure.
-
Different spinal morphine doses for pain relief after hip replacement
This trial tests whether different doses of morphine given with spinal anesthesia reduce pain and balance safety after total hip replacement in adults.
-
Opioid-free anesthesia for abdominal surgery
This study is testing whether using an opioid-free anesthesia for abdominal surgery can help patients feel less pain and have fewer side effects compared to traditional anesthesia that includes opioids.
-
Reducing unnecessary medications in elderly patients with multiple prescriptions
This study tests a new way to help older adults with multiple prescriptions cut down on unnecessary medications by working closely with their doctors and pharmacists.
