Tips and tricks to make your trauma care a bit smoother * To secure a chest tube to the chest wall quickly and easily, use the ETT holder as a temporary measure Source: Vanessa Cardy, Twitter * If the FAST is negative and you still suspect intra-abdominal bleeding, but the patient cannot get to the CT scanner for whatever reason, scrutinize the tip of the liver and the left and right sub-diaphragmatic spaces as blood will often be seen first on PoCUS in these areas, especially if the patient is placed into Trendelenburg Fluid in the subdiaphragmatic space. Source: Radiologykey.com * Place a pelvic binder on the stretcher before the patient arrives and and secure it on the patient ASAP, before imaging, if they are hemodynamically unstable without an obvious cause; but don't forget to shoot a pelvic x-ray soon thereafter in case the binder has not fully reduced the fracture * On the initial CXR do not forget to look at the bones/joints as well as the thorax as an unexpected shoulder dislocation for example, should ideally be reduced before the patient goes to the O.R. for another reason * For patients who receive ketamine during their trauma resuscitation, consider starting a ketamine drip or adding a benzodiazepine (if they are hemodynamically stable) to avoid an emergence reaction from the ketamine during transport Toxic megacolon: A tricky diagnosis * Definition: acute colonic dilatation >6cm involving at least the transverse colon, with signs of systemic illness * Common etiologies: IBD, C.Difficile colitis, CMV or parasite infections, ischemic colitis, lymphoma * Risk Factors: age >40, anticholinergic or narcotic medication use, electrolyte abnormalities, barium enemas or recent colonoscopy * Presentation: abdominal pain (not typically peritonitic early on), distension, bloody diarrhea, metabolic acidosis/alkalosis, electrolyte disturbances, elevated WBC (Note: steroids can mask symptoms) * Management: treat underlying cause, IV fluids, antibiotics, pressors as needed, steroids (only after consultation with specialist service) * Indications for Surgery: necrosis, perforation, ischemia, abdominal compartment syndrome, end organ injury or worsening clinical status =>Bottom line: the triad of bloody diarrhea, belly pain and distention in someone with a colitis history of any kind,
