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.

Fluoroscopic guidance is frequently utilized in performing various types of interventional techniques. The major purpose of fluoroscopy is accurate needle placement to ensure target specificity and accurate delivery of the injected drug. However, radiation exposure may be associated with risks to physician, patient, and personnel. Multiple studies have evaluated the risk of radiation exposure and techniques to reduce the risk in private practice settings. However, the literature is scant in evaluating the risk of radiation exposure in teaching hospitals in university settings. ⋯ The results of this study show that the fluoroscopy exposure time for various interventional procedures performed in the university settings are significantly higher than the radiation exposure periods in private practice settings. This study also showed significant differences among physicians in the same university setting.

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.

Case ReportsTwo cases of a wrong-site peripheral nerve block and a process to prevent this complication.
The purpose of this study was to develop a system to prevent laterality errors while performing peripheral nerve blockade. ⋯ The anesthesiologist plays an important role in preventing wrong-site peripheral nerve blockade and surgery. The protocol developed for "Pre-Anesthetic Site Verification" as a supplement to our preoperative site verification policy is invaluable in preventing wrong-site anesthesia and surgery.
