Randomized Controlled Trial Clinical Trial
0.2% ropivacaine with or without fentanyl for patient-controlled epidural analgesia after major abdominal surgery: a double-blind study.
To evaluate the effects of adding low concentration of fentanyl to 0.2% ropivacaine when providing patient-controlled epidural analgesia (PCEA) outside the Post-Anesthesia Care Unit. ⋯ A thoracic epidural infusion of 0.2% ropivacaine, with or without fentanyl, provided effective pain relief in most patients with a very low degree of motor blockade. Adding 2 microg/ml fentanyl to 0.2% ropivacaine reduced total consumption of local anesthetic solution and need for incremental doses, but did not provide clinically relevant advantages in quality of pain relief and incidence of motor block, leading to a significant decrease in peripheral SpO(2), lasting up to 48 hours after surgery.

Randomized Controlled Trial Clinical Trial
Warmed humidified inspired oxygen accelerates postoperative rewarming.
To investigate the efficacy of warmed, humidified inspired oxygen (O(2)) for the treatment of mildly hypothermic postoperative patients. ⋯ Warming and humidifying inspired O(2) hastens recovery from hypothermia in postoperative patients.
