Randomized Controlled Trial[Chronic postoperative pain after general anesthesia with or without a single-dose preincisional paravertebral nerve block in radical breast cancer surgery].
Over 50% of patients still experience pain a year after mastectomy with or without lymphadenectomy. We aimed to determine the association between anesthetic technique, acute postoperative pain intensity, and the development of chronic postoperative pain. ⋯ Four to 5 months after mastectomy, fewer cases of chronic pain developed in the group operated under general anesthesia with a preincisional paravertebral block than in the group that received only general anesthesia, with postoperative morphine chloride for analgesia.

Randomized Controlled Trial Multicenter Study Comparative Study[Efficacy of low-dose oxytocin during elective cesarean section].
In cesarean section, the optimal dose of oxytocin to reduce the risk of hemorrhage with the least risk of adverse effects has yet to be defined. We studied the effects of using 2 different doses of oxytocin in women undergoing elective cesarean section under spinal anesthesia. The women had had no prior labor. ⋯ The incidence of obstetric bleeding is not higher when a lower dose of oxytocin is used; the rate of postoperative adverse events also does not increase.

Randomized Controlled Trial Comparative Study[Prophylaxis for hypotension during cesarean section under spinal anesthesia: a randomized trial comparing hydroxyethyl starch 130/0.4 to ephedrine].
Spinal anesthesia is the technique of choice for scheduled or emergency cesarean section, but the prevalence of hypotension is high in this setting. Our aim was to compare the efficacy of a colloid (6% hydroxyethyl starch [HES] 130/0.4) to ephedrine for preventing hypotension. ⋯ HES 130/0.4 is as useful for hypotension prophylaxis as 5-mg or 10-mg intravenous doses of ephedrine. HES 130/0.4 might be a substitute for sympathomimetic agents if adverse effects are predicted or contraindications to the use of such drugs are present.

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.
