Comparative StudyGlobal end-diastolic volume during different loading conditions in a pediatric animal model.
Estimating volume status in infants and neonates is challenging. Global end-diastolic volume (GEDV) and dynamic variables of preload, such as pulse pressure variation (PPV), may be alternative variables for estimating cardiac preload and fluid responsiveness. Therefore, we designed the present study to evaluate whether GEDV and PPV are suitable variables of preload and fluid responsiveness during rapidly changing loading conditions in a pediatric animal model. ⋯ In this pediatric animal model, GEDV derived from transpulmonary thermodilution was a reliable indicator of cardiac preload. Moreover, GEDV but not PPV, central venous pressure and pulmonary capillary wedge pressure accurately reflected fluid responsiveness.

Meta Analysis Comparative StudyThe safety and efficacy of fentanyl iontophoretic transdermal system compared with morphine intravenous patient-controlled analgesia for postoperative pain management: an analysis of pooled data from three randomized, active-controlled clinical studies.
Postoperative pain is often managed using IV patient-controlled analgesia (PCA). In this analysis of pooled data, we compared the safety and efficacy of the fentanyl iontophoretic transdermal system (ITS) with morphine IV PCA. ⋯ These pooled data represent one of the largest head-to-head comparisons of fentanyl versus morphine in a postoperative acute pain setting. Results suggest that fentanyl ITS is effective across subpopulations defined by age and BMI, and support a consistent safety and efficacy profile of fentanyl delivered by fentanyl ITS for postoperative pain management.

Review Case ReportsPain management in a patient with intractable spinal cord injury pain: a case report and literature review.
Chronic pain is one of the more disturbing sequelae of spinal cord injury, often interfering with the basic activities, effective rehabilitation, and quality of life of the patient. Pain in the cord-injured patient is often recalcitrant to treatment. ⋯ We present a patient with intractable spinal cord injury pain who was successfully treated with a pain management plan that addressed the various aspects of spinal cord injury pain. The evidence for treatment options is reviewed.

ReviewContinuous airway access for the difficult extubation: the efficacy of the airway exchange catheter.
The American Society of Anesthesiologists Task Force on the Management of the Difficult Airway regards the concept of an extubation strategy as a logical extension of the intubation process, although the literature does not provide a sufficient basis for evaluating the merits of an extubation strategy. Use of an airway exchange catheter (AEC) to maintain access to the airway has been reported on only a limited basis. ⋯ Maintaining continuous access to the airway postextubation via an AEC can be an important component of an extubation strategy in selected difficult airway patients. The indwelling AEC appears to increase the first-pass success rate in patients with known or suspected difficult airways and decrease the incidence of complications in patients intolerant of extubation and requiring tracheal reintubation.
