BACKGROUND Postoperative pain is one of the most common problems after hernia repair. Decrease in postoperative pain accelerates functional recovery, decreases duration of hospital stay and postoperative morbidity. OBJECTIVES To compare postoperative analgesic effect of infiltration of magnesium versus bupivacaine into incision of inguinal hernia repair. PATIENTS AND METHODS In a double bli...

PURPOSE Bupivacaine is commonly used for the treatment of back pain and the diagnosis of its origin. Nonunion is sometimes observed after spinal fusion surgery; however, whether the nonunion causes pain is controversial. In the current study, we aimed to detect painful nonunion by injecting bupivacaine into the disc space of patients with nonunion after anterior lumbar interbody fusion (ALIF) s...

BACKGROUND Blockade of the ilioinguinal and iliohypogastric nerves is a useful procedure in paediatric patients undergoing inguinal surgery. Bupivacaine 2 mg kg-1 has been recommended for this block. We compared the plasma concentrations of ropivacaine and bupivacaine following an ilioinguinal-iliohypogastric block. METHODS Forty children scheduled for elective inguinal surgery were randomize...

BACKGROUND Ideal postoperative pain management requires a multidisciplinary approach in combination with a variety of dosage regimens. Approximately 21-30% of patients experience moderate to severe pain in the postoperative period, which may have a significant impact on recovery rate, standard of living, psychological health, and postoperative complications. OBJECTIVE Analysis of the incidenc...

BACKGROUND AND OBJECTIVES Several studies were performed with bupivacaine isomers in the attempt to find a safer drug than racemic bupivacaine. This study aimed at evaluating the efficacy of 0.5% bupivacaine enantiomeric mixture (MEE50%) as compared to 0.5% racemic bupivacaine in brachial plexus block for upper limb orthopedic surgery. METHODS Participated of this randomized double-blind stud...

BACKGROUND Multimodal analgesia following total hip arthroplasty has been shown to improve patient satisfaction, participation with physical therapy, and allow early return to self care. Liposomal bupivacaine is a formulation of local anesthetic which has the potential to provide anesthesia for up to 72 hours following administration. The purpose of this study was to compare the effectiveness o...

Both local anaesthetics and calcium antagonists depress cardiac function. Therefore, we have studied the interaction of these compounds in the isolated myocardium of guineapigs. The negative inotropic effect of various local anaesthetics was investigated in left atria in the absence or presence of nitrendipine 10(-7) mol litre-1 (n = 7-8 in each group). In addition, the effect of bupivacaine wa...

The aim of the present study was to compare the amount of motor block produced by different loading doses of ropivacaine and bupivacaine when delivered in a dilute solution with added opioid. Sixty-eight healthy term primigravid parturients were randomized to receive an initial bolus dose of 10 mL of 1 of the following: 0.25% bupivacaine (high bupivacaine), 0.25% ropivacaine (high ropivacaine),...

BACKGROUND Resuscitation following bupivacaine-induced cardiovascular collapse is difficult and often refractory to conventional treatment. This study was performed to assess the effect of insulin on bupivacaine-induced cardiovascular collapse in pentobarbital-anesthetized rabbits. METHODS Bupivacaine was administered at 0.75 mg/kg/min until the heart rate decreased to 65 beats/min. A bolus o...

We have compared the hypnotic requirements for i.v. propofol when combined with i.m. lignocaine or bupivacaine. Ninety women (ASA I, II) undergoing minor gynaecological surgery were allocated randomly to one of nine groups of 10 patients to receive propofol combined with i.m. lignocaine, bupivacaine or saline, respectively. Propofol was administered in bolus doses of 0.2 mg kg-1 every 30 s unti...
