Randomized Controlled Trial Clinical Trial
Is the effect of inguinal field block with 0.5% bupivacaine on postoperative pain after hernia repair enhanced by addition of ketorolac or S(+) ketamine?
The aim of the study was to assess whether coadministration of S(+) ketamine or ketorolac would enhance or prolong local analgesic effect of bupivacaine after inguinal hernia repair. ⋯ The addition of S(+)-ketamine or ketorolac only minimally improves the analgesic effect of bupivacaine. This may be related to the tension-free hernia repair technique associated with low postoperative pain.

Randomized Controlled Trial Comparative StudyAnesthetic efficacy of bupivacaine solutions in inferior alveolar nerve block.
The purpose of this study was to compare the anesthetic efficacy of 2 bupivacaine solutions. Twenty-two volunteers randomly received in a crossover, double-blinded manner 2 inferior alveolar nerve blocks with 1.8 mL of racemic bupivacaine and a mixture of 75% levobupivacaine and 25% dextrobupivacaine, both 0.5% and with 1 : 200,000 epinephrine. ⋯ No differences were found between the solutions for onset and duration of pulpal anesthesia and duration of soft tissue anesthesia (P > .05). It was concluded that the solutions have similar anesthetic efficacy.

Clinical TrialCombined neurolytic block of celiac, inferior mesenteric, and superior hypogastric plexuses for incapacitating abdominal and/or pelvic cancer pain.
Thirty-five patients with extensive abdominal or pelvic cancer who suffered uncontrolled, diffuse, extensive, and incapacitating pain were treated with a combination of neurolytic celiac plexus block (CPB), inferior mesenteric plexus block (IMPB), and superior hypogastric plexus block (SHGPB). The combination of neurolytic CPB, IMPB, and SHGPB was performed with alcohol, mainly using a transintervetebral disc approach. The combination neurolysis produced effective immediate pain relief in all the patients (visual analog scale (VAS), reduced from 8.8 +/- 0.2 to 0). ⋯ No serious complications were observed to have been caused by the neurolytic procedure on the three sympathetic plexuses. Our preliminary clinical results suggest that the combination of neurolytic CPB, IMPB, and SHGPB improves the quality of life of patients who have incapacitating cancer pain, by reducing both the intensity of the pain and their opioid consumption, without serious complications. This combination procedure may provide a new therapeutic option for pain relief in patients with advanced cancer.

Remifentanil for analgesia during retrobulbar nerve block placement.
Patients undergoing eye surgery under regional anaesthesia often require concomitant medication for analgesia and comfort. Remifentanil, with its ultra-short acting-profile, may be useful to reduce pain during retrobulbar nerve block for cataract surgery. ⋯ In patients undergoing retrobulbar block placement for eye surgery, 0.3 microg kg(-1) remifentanil over 30 s significantly reduced their reported pain. In addition, remifentanil did not increase the risk of untoward side-effects.

Thermogangliolysis of the Gasserian ganglion under computed tomography fluoroscopy.
Gasserian ganglion block is an established treatment for trigeminal neuralgia. A landmark approach assisted by X-ray fluoroscopy is the most common method; however, visualization of the foramen ovale is difficult in some cases. Here we report two cases in which a novel technique using modern computed tomography (CT) fluoroscopy was employed. ⋯ Satisfactory analgesia was obtained in this case without any complications. Another patient (65 years old) was also treated by the same technique, and satisfactory pain relief was obtained. In conclusion, CT fluoroscopy-guided Gasserian ganglion thermolysis is considered a safe, quick, and effective treatment for trigeminal neuralgia.
