To quantify the effects of sevoflurane on autonomic nerve function by analyzing changes in heart rate (HR) variability in sevoflurane anesthesia; and to investigate the effects of anesthetic depth and apnea on HR variability. ⋯ Autonomic nerve activity was attenuated by sevoflurane. Parasympathetic input to the heart by respiration was markedly suppressed following the appearance of isoelectric EEG.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of the morphine-sparing effects of diclofenac sodium and ketorolac tromethamine after major orthopedic surgery.
To compare the efficacy of diclofenac sodium with ketorolac tromethamine in reducing postoperative morphine use after major orthopedic surgery. ⋯ Preoperative administration of intravenous diclofenac 75 mg or ketorolac 60 mg significantly reduces morphine requirements and associated side effects after major orthopedic surgery.

To assess complications of regional as well as general anesthesia in parturients with Chiari I malformation. ⋯ General anesthesia, as well as spinal and epidural anesthesia, appeared to be safe and effective in our series of vaginal or cesarean delivery patients. The small number of patients in our series does not negate the cautious recommendations of others, but suggests that general anesthesia, as well as spinal or epidural anesthesia, can be used safely and effectively in these patients.

Randomized Controlled Trial Clinical Trial
Efficacy of ultrasound imaging in obstetric epidural anesthesia.
To assess the clinical use of ultrasonographic localization of the epidural space, and to evaluate the clinical efficacy of ultrasound diagnostics in obstetric anesthesia. ⋯ The clinical use of ultrasound for epidural catheter placement may improve regional anesthesia. The use of ultrasound resulted in superior quality in all measured endpoints.

Randomized Controlled Trial Comparative Study Clinical Trial
Nitrous oxide does not improve sevoflurane induction of anesthesia in adults.
To compare the characteristics of sevoflurane induction with and without the addition of nitrous oxide (N(2)O) using tidal breathing inhalation induction without priming of the breathing circuit. ⋯ The addition of N(2)O does not confer any clinically significant advantage in this method of sevoflurane induction in adults.
