Currently, the Wallace Rule of Nines is the most widely used method to measure total body surface area (TBSA) in burned patients due to its practicality and speed in its application; however, it often provides inaccurate estimations in obese patients, affecting the fluid resuscitation process. ⋯ We found important differences in TBSA determination using the 3D Skanect-MeshmixerⓇ software compared with the Wallace Rule of Nines. Therefore, we generated a modified and optimized Wallace Rule of Nines estimations based on BMI. Future studies are needed to assess the safety and efficacy of this optimized table.

Opioid overdose deaths in 2021 were the highest ever, driven by fentanyl and polysubstance use. ⋯ Most participants had UDS specimens containing multiple substances; a high proportion had fentanyl, stimulants, and buprenorphine. Regional differences were noted. Given the increased risk of death with fentanyl and polysubstance use, ED providers should be providing risk reduction counseling, treatment, and referral.

The use of supplemental oxygen (SO) for procedural sedation and analgesia (PSA) is recommended in many guidelines, but the evidence of SO for the elderly is limited. ⋯ In a propensity-matched analysis, SO was associated with a lower incidence of hypoxia in elderly patients during ED PSA.

Tube thoracostomy is rarely associated with serious bleeding complications. Although intercostal artery injury is a well-known bleeding complication, other vascular injuries in the chest wall have only rarely been reported. ⋯ A 58-year-old man with alcoholic liver cirrhosis presented to the emergency department with dyspnea. He was diagnosed by chest computed tomography with spontaneous hemopneumothorax, for which he underwent tube thoracostomy. However, bleeding in the chest wall continued, which required chest tube removal and blood transfusion. Contrast-enhanced computed tomography and angiography revealed contrast extravasation from the thoracodorsal artery, which confirmed a diagnosis of thoracodorsal artery injury. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Because the thoracodorsal artery gives branches to the serratus anterior muscles that are located in the "triangle of safety," chest tube placement in this area is not always safe; it can still cause major bleeding complications from vessels such as the thoracodorsal artery. Hence, close monitoring for bleeding is needed after tube thoracostomy.

This study evaluated the predictive value of different laboratory indicators for the severity of acute cholangitis (AC) according to the 2018 Tokyo Guidelines. ⋯ PCT can be used as a reliable predictor of severe AC. CRP was most predictive of moderate AC, whereas PLR was most predictive of blood culture positivity.
