Back in September of 2009 Michelle shared valuable Tricks of The Trade regarding drainage of peritonsillar abscesses. Today we revisit the topic and add two more tricks to avoid hitting “big red” a.k.a. the internal carotid artery.
A paracentesis procedure is often performed in the Emergency Department to rule a patient out for spontaneous bacterial peritonitis (SBP).
This installment of the Paucis Verbis (In a Few Words) e-card series provides an evidence-based review of the literature on topics related to the paracentesis procedure. Especially helpful is the pooled data of likelihood ratios. Like most everything in medicine, a lab test should be used in conjunction with your pretest probability in clinical decision making, and LR’s help with with this.

Can you see the pneumothorax?
Small pneumothoraces can be difficult to detect on chest xrays. Overlying ribs, other bony structures, and soft tissue can obscure subtle findings. For a patient at risk for a small pneumothorax, you can use your digital radiology PACS system to improve your ability to spot them.
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.

How do you approach the repair of scalp lacerations in a child? What factors are you considering?
This trick of the trade pearl addresses the stapling technique for scalp laceration repair. Perhaps the child’s hair is too short for the HAT trick.
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.

I rarely access the femoral vein for central venous catheterization… except in medical or trauma resuscitations. Oftentimes in these resuscitations, there are too many people near the IJ or subclavian vein site. People are intubating, performing CPR, trying to get peripheral vein access, etc.
