Antinociceptive Effect of Vapocoolant Medium Stream Spray onHotplate LatencyinRat Pups.
Heel sticks account for most blood tests performed in neonates without analgesia because topical local anesthetics are ineffective on heel glabrous skin. We investigated the antinociceptive effect of an alternative topical analgesic, a vapocoolant spray, on hind paw glabrous skin of rat pups. The spray was applied by two methods: method 1 for 4 s at a distance of 8 cm and method 2 for 10 s at a distance of 18 cm. ⋯ Compared with method- 1, the vapocoolant spray in method 2 produced significantly longer withdrawal latency time that is clinically applicable to collecting blood samples after a heel stick.

ReviewAdultcongenital heart disease and anesthesia:an educational review.
Prognosis has dramatically improved among children with congenital heart disease (CHD), and the median survival for severe CHD is currently 25 years (ie, into adulthood). However, additional cardiac surgeries are often necessary in adults with CHD, whose unique cardiovascular anatomy and physiology necessitate specialized management by experts in adult CHD (ACHD) during the perioperative period. ACHD is characterized by a combination of congenital cardiac lesions, intervention-related anomalies that have developed over time, comorbidities caused by long-standing CHD, and comorbidities related to various syndromes and lifestyle factors. The present educational review discusses the transition from pediatric to adult cardiac care, comorbidities that develop as a result of ACHD, the assessments necessary for patients with ACHD prior to both cardiac and noncardiac surgeries, and the key ACHD lesions relevant to perioperative management.

Simulated dimensional compatibility of uncuffed and cuffed tracheal tubes for selective endobronchial intubation in children.
Cuffed tracheal tubes have recently been recommended for selective endobronchial intubation to establish single-lung ventilation even in smaller children. This implies that, compared with uncuffed tracheal tubes, the cuffed tracheal tubes selected will be smaller and therefore have a shorter length. We hypothesized that cuffed tracheal tubes might be of insufficient length for selective endobronchial intubation if the tube cuff were fully immersed in the left or right mainstem bronchus. ⋯ For many age groups of patients requiring selective endobronchial intubation, the lengths of cuffed tracheal tubes, in contrast to those of uncuffed tracheal tubes, were revealed to be critically short for safe taping outside the oral cavity with the cuff placed completely within the right or left mainstem bronchus.
