Case Reports
Near-fatal anaphylaxis caused by human serum albumin in fibrinogen and erythrocyte concentrates.
A 40-year-old man developed anaphylactic shock during surgical replacement of a prolapsed mitral valve during general anaesthesia and an attenuated reaction (Grade 2), three days later during a blood transfusion. Human serum albumin, a component of the fibrinogen concentrate used postoperatively with the erythrocyte concentrate, was identified as the trigger, confirmed by positive skin prick and intradermal tests. Any anaphylaxis during the peri-operative period should cause the clinician to perform allergy tests for identification of the culprit drug and, sometimes, culprit additive. Testing of human serum albumin, acting as hidden allergen, should be included, especially where there has been a blood transfusion.

The purpose of this article is to review the literature and to highlight current practice regarding the management of the chronic pain patient presenting for surgery. ⋯ Successful management of the complex pain patient requires knowledge of the art and science of perioperative medicine.

Assessment of Hemoglobin Threshold for Packed RBC Transfusion in a Medical-Surgical PICU.
Results of a large multicenter randomized clinical trial published in 2007 demonstrated no benefit in using a liberal versus conservative RBC transfusion threshold in stable critically ill children. Using the conservative threshold decreased the number of RBC transfusions without increasing adverse outcomes. We aimed to determine if wide dissemination of this evidence altered the hemoglobin threshold used for RBC transfusions in our pediatric medical-surgical ICU. ⋯ Although transfusion thresholds in potentially stable critically ill children in our PICU significantly decreased after dissemination of best available evidence, 71% of patients were transfused at a hemoglobin threshold more than 7 g/dL.

Observational StudyPostoperative Neutrophil Gelatinase-Associated Lipocalin Predicts Acute Kidney Injury After Pediatric Cardiac Surgery.
We investigated the temporal pattern and predictive value of neutrophil gelatinase-associated lipocalin for early identification of acute kidney injury in children undergoing cardiac surgery. ⋯ Urine neutrophil gelatinase-associated lipocalin is a predictive biomarker for acute kidney injury after pediatric cardiac surgery, and it may permit earlier intervention that improves outcome of acute kidney injury. Urine neutrophil gelatinase-associated lipocalin normalized to urine creatinine improves the prediction of acute kidney injury severity but offers no advantage in acute kidney injury diagnosis.
