Pressure cookers are common kitchen appliances with a good safety record and only rare associated explosions. ⋯ Here we present a case of unintentional pressure cooker explosion leading to polytrauma with injuries including pneumothorax, intracranial hemorrhage, open skull fracture, and multiple facial fractures. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Extreme forces and temperatures are involved in pressure cooking. Given the infrequent but real risk of mechanical failure and the increasing use of such devices to create intentional explosions, emergency physicians should be aware of the potentially significant blast injuries that can be associated with them.

Randomized Controlled Trial
Does Intravenous Lactated Ringer's Solution Raise Serum Lactate?
Serum lactate increases in states of severe sepsis and shock, but its interpretation may be subject to confounders. Lactated Ringer's solution (LR) is used in the resuscitation of septic patients and contains 28 mmol/L of sodium lactate. ⋯ In healthy individuals, a modest but significant rise in mean serum lactate was seen after a 30 cc/kg LR bolus. There was no difference in mean serum lactate when comparing a 30 mL/kg bolus of NS to LR.

Colchicine ingestion is rare but highly lethal. Patients usually die of multiorgan failure and cardiogenic shock. Colchicine is not only associated with depressed myocardial function but also with fatal heart rhythm disturbances, such as complete heart block, ventricular tachycardia, and asystole. While histologic changes of myocytes are well known, the mechanism by which colchicine affects cardiac impulse generation and conduction is not fully understood. ⋯ We present a case of colchicine ingestion with sinus bradycardia, marked sinus arrhythmia, and first- and second-degree heart block. A 10-year-old previously healthy boy was brought to the emergency department for the sudden onset of dizziness, abdominal pain, and vomiting after ingesting his grandfather's colchicine and furosemide. His symptoms improved with ondansetron and intravenous normal saline. However, because of the colchicine ingestion, he was admitted to the pediatric intensive care unit for observation. He first developed PR prolongation (∼4-30 h postingestion) followed by marked sinus bradycardia and sinus arrhythmia along with second-degree heart block (∼48-60 hours postingestion). The minimum heart rate was 40 beats/min. Marked sinus arrhythmia was observed, suggesting an increase in parasympathetic activity. His heart rhythm improved initially with less sinus arrhythmia followed by resolution of heart block. He was discharged home without any sequelae. Holter monitoring 1 week after discharge showed normal heart rate variability for age. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case provides novel insights into how colchicine may affect the heart's electrophysiology. Colchicine may increase the parasympathetic tone enough to cause sinus bradycardia and different degrees of heart block.

The emergency care system for children in the United States is fragmented. A description of epidemiological trends based on emergency department (ED) volume over time could help focus efforts to improve emergency care for children. ⋯ Overall, pediatric ED visits have remained stable, with lower mortality rates, whereas Medicaid-funded pediatric visits have increased over time. Most children still seek care in lower-volume EDs. Efforts to improve pediatric care could be best focused on lower-volume EDs and interhospital transfers.
