Anesthesia is generally accepted as safe in most adult populations; however, in pediatric patients questions exist regarding the potential for long-term detrimental effects. Various anesthetic agents are associated with neuronal degeneration when administered to neonatal animals. The mechanism of damage is thought to be via accelerated apoptosis, a normally beneficial process in the maintenance of homeostasis. ⋯ Clear evidence exists that neuronal apoptosis occurs when anesthetics are administered to neonatal rodents and primates, and behavioral and cognitive testing from some authors indicate long-term effects persist well into an animal's adulthood. Preliminary human trials reveal a link between anesthesia and subsequent developmental delays. This review of the literature clarifies the need for further research in humans.

The purpose of this study was to determine and compare the maximum concentration (C(max)) and time to maximum concentration (T(max)) of epinephrine administered via tibial intraosseous (IO), sternal IO, and intravenous (i.v.) routes in a porcine model of cardiac arrest during cardiopulmonary resuscitation. Five pigs each were randomly assigned to 3 groups: tibial IO, sternal IO, and i.v. Cardiac arrest was induced with i.v. potassium chloride. ⋯ There were significant differences in Cmax between the sternal IO and i.v. (P = .009) and tibial IO and i.v. (P = .03) groups but no significant difference between tibial and sternal IO groups (P = .75). Significant differences existed in Tmax between the tibial IO and i.v. (P = .04) and between tibial IO and sternal IO (P = .02) groups but no difference between the sternal IO and i.v. groups (P = .56). Intravenous administration of 1 mg of epinephrine resulted in a serum concentration 5.87 and 2.86 times greater than for the tibial and sternal routes, respectively.

Perioperatively, insulin to treat hyperglycemia is administered judiciously to minimize the risk of hypoglycemia. In patients with diabetes in whom preoperative blood glucose levels are on the low end of normal, hypoglycemia risk may be underestimated. This retrospective study enrolled subjects with presenting preoperative blood glucose values in these ranges: 70 to 89 mg/dL (low normal group) and above 249 mg/dL (hyperglycemia-treated group). ⋯ Accounting for differences between groups, the incidence of perioperative blood glucose levels below 70 mg/dL was greater in the low normal group than the hyperglycemia-treated group (17.2% vs 3.6%, P < .001). Of subjects whose blood glucose levels fell below 70 mg/dL, blood glucose levels dropped below 50 mg/dL in 40% of hyperglycemia-treated subjects and 4% of low normal subjects. Perioperative hypoglycemia was likelier to develop in patients with diabetes who presented preoperatively with low normal blood glucose values than in patients treated with insulin for presenting hyperglycemia.

Airway management following severe gasoline burn injury can be difficult. Because patients with severe burns may be treated at a variety of hospitals that provide emergent care, it is valuable for Certified Registered Nurse Anesthetists who work in such facilities to have an understanding of the care of these patients. Airway management is an extremely important consideration in the care of burn victims. ⋯ This article reports the experience of caring for a female who was involved in an altercation, doused with gasoline, and set on fire. Consequently, airway obstruction developed and progressively worsened. Airway management interventions began with bag-valve-mask-assisted ventilation and progressed through orotracheal intubation attempts, attempts to insert a laryngeal mask airway, cricothyrotomy, emergency tracheostomy, and surgical tracheostomy.

Postoperative sore throat and hoarseness are common and disturbing complications following endotracheal intubation, and women are more frequently affected by these symptoms. This study explores risk factors associated with postoperative sore throat and hoarseness in women following intubation. In this prospective cross-sectional study, 97 patients undergoing elective ear, nose, and throat surgery or plastic surgery were included. ⋯ Three variables were found to be significant risk factors for postoperative sore throat: age greater than 60 years (P = .01), the use of a throat pack (P = .04), and endotracheal tube No. 7.0 (size 7 mm; P = .02). The only risk factor found to be significantly associated with developing hoarseness was an endotracheal cuff pressure below 20 centimeters of water (P = .04). Larger studies are needed to confirm these risk factors.
