Randomized Controlled Trial Comparative StudyProphylactic versus reactive transfusion of thawed plasma in patients undergoing surgical repair of craniosynostosis: a randomized clinical trial.
Surgical repair of craniosynostosis in young children is associated with copious bleeding and often coagulopathy. Typically, a reactive transfusion strategy is used to treat coagulopathy whereby fresh frozen plasma (FFP) is given only after clinical manifestation of clotting abnormality. This prospective, randomized clinical trial was designed to test the hypothesis that prophylactic FFP during craniofacial surgery reduces blood loss and blood transfusion requirements compared to a reactive FFP transfusion strategy. ⋯ A reactive FFP transfusion strategy required less plasma transfusion and was associated with similar rates of blood loss and PRBC transfusion as prophylactic FFP despite improvement in coagulation values in the prophylactic FFP group.

Review Case ReportsAnesthetic considerations in myofibrillar myopathy.
Myofibrillar myopathy (MFM) is a relatively newly recognized genetic disease that leads to progressive muscle deterioration. MFM has a varied phenotypic presentation and impacts cardiac, skeletal, and smooth muscles. Affected individuals are at increased risk of respiratory failure, significant cardiac conduction abnormalities, cardiomyopathy, and sudden cardiac death. ⋯ This study is the first report of anesthetic management of a patient with MFM. We report multiple anesthetic encounters of a child with genetically confirmed BAG3-myopathy, a subtype of MFM with severe childhood disease onset. A review of the anesthetic implications of the disease is provided, with specific exploration of possible susceptibility to malignant hyperthermia, rhabdomyolysis, and sensitivity to other anesthetic agents.

Ultrasound assessment of gastric volume in the fasted pediatric patient undergoing upper gastrointestinal endoscopy: development of a predictive model using endoscopically suctioned volumes.
Aspiration of gastric contents can be a serious anesthetic-related complication. Gastric antral sonography prior to anesthesia may have a role in identifying pediatric patients at risk of aspiration. We examined the relationship between sonographic antral area and endoscopically suctioned gastric volumes, and whether a 3-point qualitative grading system is applicable in pediatric patients. ⋯ The results suggest that sonographic assessment of the gastric antrum provides useful information regarding gastric content (empty versus nonempty) and volume (ml·kg(-1) ) in pediatric patients. Results suggest that the three-point grading system may be a valuable tool to assess gastric 'fullness' based on a qualitative exam of the antrum.

Clinical TrialSedation monitoring during open muscle biopsy in children by Comfort Score and Bispectral Index - a prospective analysis.
Open muscle biopsies in children are generally performed under general anesthesia. Alternatively, deep sedation and analgesia may be required. ⋯ Bispectral Index provides an additional helpful tool to guide sedation/analgesia in minor surgical procedures in children. BIS values ≤60 correlated with sufficient depth of sedation and prevented unintended awareness. Additionally, BIS measurement allowed for distinct regulation of depth of sedation without prolonged sedation/analgesia due to unintended overdose.

Comparative StudyA comparison of functional magnetic resonance imaging findings in children with and without a history of early exposure to general anesthesia.
Functional magnetic resonance imaging (fMRI) has been used to evaluate the long-term consequences of early exposure to neurotoxic agents. fMRI shows that different patterns of brain activation occur in ethanol-exposed subjects performing a go/no-go response inhibition task. Pharmacologically, ethanol and general anesthetics have similar receptor-level activity in the brain. This study utilizes fMRI to examine brain activation patterns in children exposed to general anesthesia and surgery during early brain development. ⋯ Early anesthetic exposure and surgery did not affect accuracy, response time, or activation patterns in the primary region of interest during performance of the task. Intergroup differences in activation patterns in other areas of the brain were observed, and the significance of these findings is unknown. fMRI appears to be a useful tool in evaluating the long-term effects of early exposure to general anesthesia.
