ReviewA qualitative systematic review of morphine treatment in children with postoperative pain.
Postoperative pain management in children is often empirical rather than evidence based. Morphine is the pharmacological treatment most widely used and although considered safe for children, adequate scientific data on morphine's pharmacokinetics, efficacy and safety are lacking. This systematic review aimed to evaluate the available literature examining different pediatric morphine regimens with respect to dosage, analgesic efficacy and incidence of side effects. ⋯ Although several factors may justify its use as first line therapy in many parts of the world, morphine alone is not the most suitable analgesic for postoperative pain in pediatric patients, as it does not have superior analgesic effect and a higher incidence of side effects compared with active control interventions. More standardized clinical trials with multimodal regimens as well as guidelines for evaluating pediatric medicines are desirable in the future.

Case ReportsCardiac arrhythmias following anesthesia induction in infantile-onset Pompe disease: a case series.
Patients with infantile-onset Pompe disease suffer from marked hypertrophic cardiomyopathy and an increased risk of arrhythmia. A noncompliant left ventricle predisposes these infants to diastolic heart failure with elevated left ventricular enddiastolic pressure (LVEDP); these patients also commonly develop systolic heart failure. Given this baseline cardiac physiology, coronary perfusion pressure becomes highly sensitive to abrupt changes in diastolic blood pressure (DBP). ⋯ With the advent of enzyme replacement therapy (ERT) using rhGAA, and increased survivability, more infantile Pompe patients will likely present for surgical procedures. Additional care in maximizing coronary perfusion pressure and minimizing arrhythmia risk must be given. For these reasons, it is recommended that anesthesia for infantile Pompe patients specifically avoid propofol or high concentrations of sevoflurane and, instead, use an agent such as ketamine as the cornerstone for induction in order to better support coronary perfusion pressure and to avoid decreasing DBP with vasodilatory agents.

Case ReportsUnilateral postoperative visual loss due to central retinal artery occlusion following cervical spine surgery in prone position.
Postoperative visual loss following spinal surgery is a rare complication. Although a number of intraoperative and postoperative factors have been implicated exact etiology still may remain unclear. We report a case of unilateral postoperative visual loss in a patient who had undergone prolonged spine surgery in a prone position.

N-terminal probrain natriuretic peptide level inversely correlates with cardiac index after arterial switch operation in neonates.
Natriuretic peptide levels are associated with cardiac output and ventricular function. We hypothesized that concomitant measurement of the peptide fragments and the hemodynamic parameters could elucidate the associations of these parameters after pediatric cardiac surgery. ⋯ NT-proBNP correlated with the hemodynamic parameters and with the severity of renal dysfunction. Therefore, NT-proBNP is a reliable indicator of the circulatory state and the severity of a low output syndrome after arterial switch operation in neonates.
