Paucis Verbis card: Appendicitis – ACEP Clinical Policy

Appendicitis is a common presentation in the Emergency Department. Dilemmas arise when deciding whether to image patients with equivocal symptoms and WBC lab results. Given the risk of ionizing radiation with CT scans, we should ideally minimize the number of CT scans ordered in these patients without mistakenly sending patients home with an early appendicitis. A perforated appendix places the patient at risk for bowel obstruction, infertility (in women), and sepsis.

Where does the American College of Emergency Physicians (ACEP) stand on the critical issues surrounding the evaluation of appendicitis?

This installment of the Paucis Verbis (In a Few Words) e-card series reviews the ACEP Clinical Policy on Appendicitis. In the end, the policy conjures up more questions than answers, but a comprehensive presentation of the literature to date and helpful risk-stratification data are provided.

Paucis Verbis card: Septic Arthritis

In the workup of monoarticular arthritis, the question that emergency physicians constantly struggle over is whether the patient has a nongonococcal septic arthritis. This joint infection alarmingly damages and erodes cartilage within only a few days.

This installment of the Paucis Verbis (In a Few Words) e-card series reviews the JAMA Rational Clinical Examination article which asks “Does this patient have septic arthritis?” Pooled sensitivities and likelihood ratios were calculated. These statistics are always helpful when trying to figure out the patients probability of having a septic joint.

I was surprised to learn that only about 50% of patients with septic joints have a fever. Note that a hip or knee prosthesis PLUS an overlying skin infection pretty much equals a septic joint (LR = 15.0).

Risk factors are listed in the table with the corresponding sensitivities, specificities, and likelihood ratios.

PV Card: Dermatomal and Myotomal Maps

There are some things in life which I just can’t memorize and dermatomal/myotomal maps are one of them. Weird cases of peripheral neurologic symptoms have presented to the ED in the setting of trauma and no trauma. So purely for selfish reasons, I’m making my own map to have on file.

Paucis Verbis card: Ottawa knee, ankle, and foot rules

Often times, I get called to triage to help decide whether a patient should be sent to Radiology for an initial x-ray after injuring their knee, ankle, and/or foot. After teaching one of the nurses about the Ottawa rules, she taped a list of these rules on the triage wall.

Paucis Verbis card: Vasopressors and Inotropes for Shock

The treatment of shock should focus on correcting the underlying pathophysiology. With persistent hemodynamic instability, a vasopressor and/or inotrope should be selected. Reviewing receptor physiology can help you select the best-fit agent for the patient’s clinical condition. There is an especially useful table on medication selection in the reviewed 2008 EM Clinics of North America article.

Trick of the Trade: Radial Gutter Splint

How do you splint 2nd or 3rd metacarpal fractures? A short arm volar splint is usually applied, because a fracture should be immobilized one joint distal and proximal to the injury. This splint, however, unnecessarily immobilizes the 4th and 5th fingers. It makes gripping things with your hand difficult.

Paucis Verbis card: Skipping the CT prior to LP for meningitis

With increasing awareness of CT’s irradiation risk, I thought I would review a classic 2001 article from the New England Journal of Medicine. Head CT’s previously were commonly performed prior to all lumbar punctures (LP) to rule-out meningitis. When can you safely go straight to an LP without imaging?

Caveat: This review only applies to those patients in whom you suspect meningitis. This does not apply to those being worked up for subarachnoid hemorrhage.
