NO metabolites and nNOS immunoreactive neurons innervating the lower lip were also increased in the TG. Intra-TG administration of nNOS substrate induced the mechanical allodynia. The present findings suggest that NO released from TG neurons regulates the excitability of TG neurons innervating the whisker pad skin, and the enhancement of TG neuronal excitability may underlie ectopic mechanical allodynia.”
“Objective: The excision of laryngeal papillomas poses a great challenge for both LY2874455 the anesthesiologist and the surgeon. The narrowness of the airways and the great variability of the pathological lesions necessitate close collaboration between the surgical and anesthesia

teams to provide optimal operating conditions and ensure adequate ventilation and oxygenation. Our aim was to explore perioperative anesthesia management in pediatric patients during the excision of laryngeal

papillomas with a suspension laryngoscope.

Methods: Fifty-eight pediatric patients suffering from laryngeal papillomas were included in this retrospective study. These patients had degrees of laryngeal obstruction from I to III and underwent suspension laryngoscopic surgery to excise laryngeal papillomas between January 2007 and December 2010. The American Society of Anesthesiologists (ASA) physical status of the patients ranged from I to III. Anesthesia was induced by intravenous administration. Once the child was unconscious, a 2% lidocaine aerosol solution was sprayed over the laryngeal area directly under the laryngoscope. For patients to tolerate suspension VE821 laryngoscopy, it is necessary to maintain spontaneous breathing and ensure adequate anesthesia depth. The airway was secured, and sufficient ventilation was established throughout a tracheal tube (ID 2.5 or A 1331852 3.0) which was placed close to glottis and connected to Jackson Rees system. Hemodynamic parameters and pulse oxygen saturation (SpO(2)) were closely monitored, and adverse events were recorded.

Results: Most of the patients 89% (52/58) were hemodynamically stable during

the perioperative period. Laryngospasm and laryngeal edema occurred in several children during emergence from the anesthesia. Tracheal intubations were performed in six patients (10.3%). Tracheotomies were performed in two patients. One patient had to be sent to the ICU for comprehensive therapy.

Conclusion: The most important consideration for anesthesia during suspension laryngoscopy is (1) the maintenance of adequate ventilation, (2) to permit surgical exposure, and (3) to maintain suitable depth of anesthesia which relaxes the vocal band, avoids laryngeal spasms (reflex closure), reduces cardiovascular reaction and wakes up quickly after operation. Any factors that aggravate laryngeal obstruction and dyspnea should be avoided. (C) 2011 Elsevier Ireland Ltd. All rights reserved.”
