Clinical usefulness, safety, and plasma concentration of ropivacaine 0.5% for inguinal hernia repair in regional anesthesia.
The aim of this study was to evaluate the pharmacokinetics, feasibility, and clinical effects of ropivacaine in regional anesthesia (ilioinguinal-iliohypogastric blocks [IIB], genitofemoral block plus local infiltration) for inguinal hernia repair. ⋯ A ropivacaine dose of 60 to 70 mL of 0.5% appears adequate for regional anesthesia for inguinal hernia repair regarding conditions for surgery, safety, ambulation, and postoperative pain relief.

Randomized Controlled Trial Clinical TrialEffects of gabapentin in acute inflammatory pain in humans.
The aim of the study was to examine the analgesic effects of the anticonvulsant, gabapentin, in a validated model of acute inflammatory pain. ⋯ The study indicates that gabapentin has no analgesic effect in normal skin, but may reduce primary mechanical allodynia in acute inflammation following a thermal injury. These observations suggest a clinical potential of gabapentin in the treatment of postoperative pain.

Randomized Controlled Trial Clinical TrialPostoperative analgesia by intraarticular clonidine and neostigmine in patients undergoing knee arthroscopy.
Clonidine and neostigmine have a central mechanism of analgesic action and are synergistic when given intrathecally. Both drugs also have a peripheral analgesic effect. The purpose of this study was to compare the analgesic effect of intraarticular clonidine and neostigmine, used separately and in combination, in patients undergoing knee arthroscopy. ⋯ Intraarticular administration of 150 microg of clonidine, 500 microg of neostigmine, or both produce postoperative analgesia, and the combination is not more effective.

Randomized Controlled Trial Clinical TrialDiclofenac and/or propacetamol for postoperative pain management after cesarean delivery in patients receiving patient controlled analgesia morphine.
A multimodal approach to postcesarean pain management may enhance analgesia and reduce side effects after surgery. This study evaluates the postoperative analgesic effects of propacetamol and/or diclofenac in parturients undergoing elective cesarean delivery under spinal anesthesia. ⋯ Diclofenac after cesarean delivery improves analgesia and has a highly significant morphine-sparing effect. We were unable to demonstrate significant morphine-sparing effect of propacetamol or additive effect of propacetamol and diclofenac in this group of patients.

Confirmation of location of epidural catheters by epidural pressure waveform and computed tomography cathetergram.
Epidural pressure has remained a relatively unused test of physiological monitoring for the past 3 decades. It is our hypothesis that epidural pressure waveforms (EPWFs) obtained by transducing an epidural catheter (EC) can be used as a surrogate for the accurate location of the EC. The goal of this study was to validate this new method by comparing it with a more objective radiographic technique such as computed tomography cathetergram (CTC). ⋯ The strong relationship between EPWF and CTC suggests that EPWF can be used reliably to confirm the correct placement of the EC in a selected group of patients.
