Epidural and spinal anesthesia enjoy wide usage in modern practice, and each can provide reliable and safe anesthesia. Although the techniques appear to the casual observer to require relatively straightforward technical skill, both are fraught with myriad hazards and potential complications. It is the familiarity with and the understanding of these complications that makes for safe and professional practice of these techniques.

Successful interscalene block with a nerve stimulator may also result after a pectoralis major motor response.
Interscalene block of the brachial plexus is a well-established anesthetic and analgesia technique for shoulder surgery. The endpoint for successful block using the nerve stimulator has been described by previous authors as a bicep motor response (twitch) and recently by a deltoid motor response. This retrospective observational case study of regular clinical practice examined the efficacy of using the pectoralis major motor response as an endpoint for a successful block. ⋯ This retrospective observational case study of regular clinical practice suggests that a pectoralis major motor response can be a satisfactory endpoint for interscalene block.

Case Reports
[CT guided neurolysis of the sphenopalatine ganglion for management of refractory trigeminal neuralgia].
The authors present the case of a patient with recurrent trigeminal neuralgia, refractory to medical treatment and ablation of the trigeminal ganglion, who underwent three separate CT guided injections for pterygopalatine ganglion ablation over a two year period. Ablation of the pterygopalatine ganglion may be an effective technique for pain management in patients suffering from atypical facial pain syndrome, cluster headache, or neuritis. The technique used for CT guided ablation using alcohol or radiofrequency is described. The advantages and pitfalls of this technique are reviewed.

Neural blockade has been used as the single method to anesthetize a part of the body or used in combination with general anesthesia to lessen perioperative pain. Currently, nerve blocks are used for diagnostic, prognostic, therapeutic and prophylactic proposes for management of chronic, acute and cancer pain in a Pain Clinic. Reviewing the records of the 3,349 patients at Siriraj Pain Clinic, we found 2,662 and 687 cases had chronic and acute pain problems respectively, and only 646 patients were treated with anesthetic interventions during 1990 to 1998. ⋯ This retrospective review showed that 38 per cent of them reported 50 per cent pain relief with temporary effect. 34 per cent experienced good and satisfactory pain relief while 9 per cent reported excellent pain relief. 17 per cent did not gain benefit from any technique of pain relief and about 2 per cent could not be evaluated due to they did not return for follow-up. One serious complication after thoracic sympatholysis was brachial plexus injury. The neural blockade is proven to be one of the useful adjunct in the management of chronic pain but the selection of the technique is subjected to its critical appraisal.

Case Reports
Unilateral Horner's syndrome and brachial plexus anesthesia during lumbar epidural blockade.
Horner's syndrome is a rare side effect of epidural analgesia. In association with ipsilateral brachial plexus block, it has only been reported once before, in French. Unilateral blockade has also been reported, although its etiology is unclear and may be multifactorial. The patient described here experienced an asymmetrical epidural blockade with a unilateral Horner's syndrome and ipsilateral brachial plexus block.
