Randomized Controlled Trial Comparative Study[Adjuvant methadone or fentanyl in spinal anesthesia with bupivacaine: a randomized, double-blind, placebo-controlled trial].
To compare the effect of combining spinal bupivacaine with either of 2 lipophilic opioids (fentanyl or methadone), testing the hypothesis that methadone would give longer-lasting analgesia. ⋯ The addition of methadone to bupivacaine significantly prolonged the postoperative analgesic effect of spinal anesthesia and shortened sensory-motor block duration, enhancing patient comfort after surgery.

Randomized Controlled Trial Comparative Study[Low-dose hypobaric spinal anesthesia for anorectal surgery in jackknife position: levobupivacaine-fentanyl compared to lidocaine-fentanyl].
To compare the percentage of patients who were able to bypass the postoperative intensive care recovery unit after selective spinal anesthesia with lidocaine-fentanyl versus levobupivacaine-fentanyl for anorectal surgery in jackknife position. ⋯ Both spinal anesthetic solutions provide effective, selective anesthesia and are associated with similar rates of recovery care unit bypass after anorectal surgery in jackknife position.
