The ganglion impar, a single structure usually found at the anterior aspect of the sacrococcygeal joint, is the lowest ganglion of the paravertebral sympathetic chain. Its blockade is indicated in visceral pain syndromes and/or sympathetic pain syndromes of the perineal region. Several approaches to this block have been described, mainly through the anococcygeal or sacrococcygeal ligaments. ⋯ After therapy the VAS decreased by an average of 50% in the whole group. There were no adverse events. Our result show that this proposed modified approach to the block and use of radiofrequency for the ganglion impar is useful for the treatment of perineal noncancer-related pain.

With the continuous development of technological advances for diagnosis and treatment comes the increased need for anesthesia outside of the operating room. Children, because of their inability to cooperate with lengthy imaging procedures or painful treatments, form the largest group needing non operating room anesthesia (NORA). As the distinction between deep sedation and general anesthesia becomes less clear, it has become increasingly common for institutions to dedicate resources for pediatric NORA (as opposed to sedation services) to improve predictability, comfort, and safety. ⋯ NORA is a specific microsystem environment that must integrate operating room systems with those of other departments and specialties. Often the children that require these procedures have chronic illnesses and return at frequent intervals with complex medical, psychological, and behavioral issues. Special knowledge, training, and support infrastructure are required to provide optimal care for these expanding services.

Intravascular Cooling in the Treatment of Stroke (ICTuS): early clinical experience.
We sought to evaluate the safety and feasibility of mild therapeutic hypothermia using an endovascular temperature management system in awake acute ischemic stroke patients. The Intravascular Cooling in the Treatment of Stroke (ICTuS) study was an uncontrolled, multicenter development and feasibility study of conscious patients (n = 18) presenting within 12 hours of onset of an acute ischemic stroke at 5 clinical sites in the United States. Enrolled patients were to undergo core temperature management using an endovascular cooling system to induce and maintain mild, therapeutic hypothermia (target temperature of 33.0 degrees C) for a period of either 12 or 24 hours, followed by controlled rewarming to 36.5 degrees C over the subsequent 12-hour period. ⋯ Increasing the duration of hypothermia administration from 12 hours to 24 hours did not appear to increase the incidence or severity of adverse effects. Endovascular cooling with a proactive antishivering regimen can be accomplished in awake stroke patients. Further studies are needed to establish the safety and efficacy of this approach.

The possibility exists for major complications to occur when individuals are intoxicated with alcohol prior to anesthetization. Halothane is an anesthetic that can be metabolized by the liver into a highly reactive product, trifluoroacetyl chloride, which reacts with endogenous proteins to form a trifluoroacetyl-adduct (TFA-adduct). The MAA-adduct which is formed by acetaldehyde (AA) and malondialdehyde reacting with endogenous proteins, has been found in both patients and animals chronically consuming alcohol. These TFA and MAA-adducts have been shown to cause the release of inflammatory products by various cell types. If both adducts share a similar mechanism of cell activation, receiving halothane anesthesia while intoxicated with alcohol could exacerbate the inflammatory response and lead to cardiovascular injury. ⋯ These results demonstrate that halothane and MAA-adduct pre-treatment increases the inflammatory response (TNF-alpha release). Also, these results suggest that halothane exposure may increase the risk of alcohol-induced heart injury, since halothane pre-treatment potentiates the HEC TNF-alpha release measured following both MAA-Alb and LPS stimulation.
