BACKGROUND Regional anesthesia techniques are increasingly preferred for caesarean section. The aim of the present study was to compare the anesthetic effects of levobupivacaine + fentanyl and bupivacaine + fentanyl on the mother and newborn during elective caesarean section under spinal anesthesia. METHODS In this prospective study, 50 gravidas, who were scheduled for cesarean section were e...

BACKGROUND Paravertebral analgesia is useful for breast surgery. Patient controlled analgesia by IV or epidural routes is well established for delivering postoperative analgesia. Our objective was to apply patient control to paravertebral analgesia and evaluate the efficacy and tolerability of two distinct dosing regimens. METHODS Patients undergoing major breast cancer surgery were recruited...

BACKGROUND Neuraxial anesthesia is utilized in children of all ages. Local anesthetics produce dose-dependent toxicity in certain adult models, but the developing spinal cord may also be susceptible to drug-induced apoptosis. In postnatal rodents, we examined the effects of intrathecal levobupivacaine on neuropathology and long-term sensorimotor outcomes. METHODS Postnatal day 3 (P3) or P7 ra...

BACKGROUND Arthroscopic knee surgery is commonly performed as an outpatient procedure and is often associated with postoperative pain. OBJECTIVES We aimed to compare the effects of intra-articular levobupivacaine-tenoxicam-tramadol and levobupivacaine-tenoxicam-morphine combinations on postoperative pain in patients undergoing elective arthroscopic knee surgery. MATERIALS AND METHODS A tota...

BACKGROUND It was aimed to compare the efficacy and adverse effects of levobupivacaine alone and in combination with fentanyl and sufentanil during transurethral resection of the prostate (TURP) under spinal anesthesia. MATERIALS AND METHODS In this prospective, randomized, double-blind trial, 60 patients undergoing elective TURP under spinal anesthesia were randomized into three groups. Ten ...

We have compared the minimum local analgesic concentrations (MLAC) of levobupivacaine relative to racemic bupivacaine in a prospective, randomized, double-blind, sequential allocation study. Women in labour were given a 20-ml bolus of epidural levobupivacaine or bupivacaine diluted to a concentration determined by up-down sequential allocation. The initial concentration was 0.07% w/v for both d...

BACKGROUND Comparing the relative potency of new local anaesthetics such as levobupivacaine and ropivacaine with bupivacaine by the minimum local analgesic concentration model has not been described for neonatal spinal anaesthesia. This information is important to compare agents and to determine the most effective spinal dose. METHODS We performed a two-stage study to determine the ED50, the ...

INTRODUCTION The aim of the study was to compare the sensory, motor, and neuroophthalmological effects of isobaric levobupivacaine and bupivacaine when intrathecally administered. MATERIALS AND METHODS A prospective, double-blind, randomized study with 60 ASA grade I-II patients aged 18-65 years awaiting knee arthroscopy under spinal anesthesia. Patients received 12.5 mg of isobaric bupivacai...

PURPOSE The authors compared the efficacy of local anesthetics levobupivacaine, bupivacaine, and lidocaine for retrobulbar anesthesia in vitreoretinal surgery. METHODS A total of 135 patients presenting for vitreoretinal surgery under local anesthesia were included in the study. Patients were randomly allocated to one of three groups. Group LB patients received 5 mL of 0.5% levobupivacaine, G...
