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.

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.

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.

Randomized Controlled Trial Comparative Study Clinical Trial
Superficial vs combined cervical plexus block for carotid endarterectomy: a prospective, randomized study.
The present study compares combined and superficial cervical plexus block in patients submitted to carotid endarterectomy (CEA) in terms of anesthetic efficacy, satisfaction of the patient and surgeon, complications resulting from the type of anesthesia, and final outcome. ⋯ Superficial cervical anesthetic block shows the same efficacy as combined block, with the surgical conditions being closely similar. The incidence of complications related to the anesthetic technique is higher for combined block. The type of block does not influence the final outcome of the patients.
