On the Streets #12: Salient Pre-hospital Considerations for Neurosurgical Emergencies - a Smorgasbord Part II

Contributor: Donald Stader, MD Educational Pearls: Hip Dislocation Prolonged dislocations can impair blood supply to femoral head Hip dislocation for >6 hours puts patient at high risk for needing a hip replacement in the next two year Knee Dislocation High mechanism Often looks anatomically normal on knee x-ray Vascular injuries of the popliteal artery can cause significant morbidity with some studies suggesting an 80% amputation rate if not treated within 6 hours Ankle Dislocation Common dislocation and often co-occurs with ankle fractures (bimalleolar/trimalleolar) Pressure on the skin from the displaced joint can cause skin tenting, which can lead to skin necrosis Hematoma blocks work well for ankle reductions as an adjunct to or substitute for procedural sedation References Arnold C, Fayos Z, Bruner D, Arnold D.

Podcast 720: Blakemore & Minnesota Tubes: Part I

Contributor: Ricky Dhaliwal, MD Educational Pearls: Multiple RCTs and a Cochrane Review found there is no difference in wound infection rates when irrigating with tap water  Pressure of the water and how extensively the wound is irrigated were the most important factors affecting infection rates Quantity and type of water were independently not as important References Fernandez R, Griffiths R. Water for wound cleansing. Cochrane Database Syst Rev. 2012;(2):CD003861. Published 2012 Feb 15. doi:10.1002/14651858.CD003861.pub3 Lewis K, Pay JL. Wound Irrigation. [Updated 2021 Jun 4].

Podcast 719: Normal Saline vs. Tap Water for Wound Irrigation

Contributor: Aaron Lessen, MD Educational Pearls: Patients with acute renal failure often need medical management for hyperkalemia Those with severe electrolyte derangements or absent renal function may need emergent dialysis as well Dialysis catheters are 12 or 14 french catheters placed in the right internal jugular or left subclavian Placement is very similar to a central line or cordis catheter Trialysis catheter is one option that has an extra port that can be used for regular medication administration and drawing blood Do not default to use dialysis catheters for normal ED access due to risk of infection and clot development While dialysis catheters are typically reserved for dialysis only, they can be used in extreme circumstances, such as a cardiac arrest References Co I, Gunnerson K. Emergency Department Management of Acute Kidney Injury, Electrolyte Abnormalities, and Renal Replacement Therapy in the Critically Ill. Emerg Med Clin North Am. 2019;37(3):459-471. doi:10.1016/j.emc.2019.04.006 Simon LV, Hashmi MF, Farrell MW. Hyperkalemia. [Updated 2021 Aug 14]. In: StatPearls [Internet].

Podcast 718: Renal Failure Follow Up

Contributor: Aaron Lessen, MD Educational Pearls: Hyperkalemia can cause EKG changes such as a widened QRS The fastest electrolyte results can be obtained off a VBG with electrolytes  or point-of-care labs Hyperkalemia may be reported as “hemolyzed” which indicated lysis of red blood cells and artificial elevation of the potassium level. However, always keep in mind the clinical context and look at other metabolic abnormalities like creatinine and BUN for other clues that it may actually not be hemolyzed References Co I, Gunnerson K. Emergency Department Management of Acute Kidney Injury, Electrolyte Abnormalities, and Renal Replacement Therapy in the Critically Ill. Emerg Med Clin North Am. 2019;37(3):459-471. doi:10.1016/j.emc.2019.04.006 Simon LV, Hashmi MF, Farrell MW. Hyperkalemia. [Updated 2021 Aug 14]. In: StatPearls [Internet].

Podcast 717: A cautionary tale of renal failure

Contributor: Nick Tsipis, MD Educational Pearls: Fluid choice may have an impact on outcomes in resuscitation, and a meta-analysis has relevant insight into their use in sepsis and trauma patients Large volume normal saline fluid resuscitation in sepsis is associated with acute kidney injury and metabolic acidosis compared to Lactated Ringers Choice of fluid did not have significant differences in trauma patients for initial resuscitation References Tseng CH, Chen TT, Wu MY, Chan MC, Shih MC, Tu YK.

Podcast 716: Resuscitation Fluids

Contributor: Nick Hatch, MD Educational Pearls: High flow nasal cannula (HFNC) or “heated high flow” can deliver higher oxygen levels than nasal cannula It typically is used as an “intermediate” between oxygen via nasal cannula and other non-invasive positive pressure devices, such as BiPAP Can modify both the FiO2 and flow rate Maximum flow rate is typically  60 liters per minute (compare that to a typical breath that is 30-40 L/min) Humidification of HFNC is important due to risk of epistaxis from drying out the nasal mucosa Large energy expenditure to humidify airflow by a patient in respiratory distress, so humidified oxygen may help decrease this metabolic demand References Nishimura M. High-Flow Nasal Cannula Oxygen Therapy in Adults: Physiological Benefits, Indication, Clinical Benefits, and Adverse Effects. Respir Care. 2016;61(4):529-541. doi:10.4187/respcare.04577 Hacquin A, Perret M, Manckoundia P, et al.

Podcast 714: Intradermal Sterile Water for Back Pain

Contributor: Don Stader, MD Educational Pearls: Those on chronic opioid therapy may have high tolerance to opioids and/or opioid hyperalgesia Ketamine is a good adjunct for pain control in patients on chronic opioid therapy To avoid the time constraints often required to push ketamine intravenously, it can be given orally: Ketamine IV 25-50 mg (~0.01-0.03 mg/kg) as a single dose by mouth References Blonk M, Koder B, et al. Use of oral ketamine in chronic pain management: A review. European Journal of Pain. 2009. Schwenk ES, et al.

Podcast 713: Oral Ketamine

Contributor: Aaron Lessen, MD Educational Pearls: Retrospective cohort study in the Kaiser system looked at over 4 million patients receiving antibiotics to determine the effect of penicillin allergy prompts in the EHR on antibiotic prescribing Half of the sites removed prompts stating penicillin allergy and half kept the prompts Patients with penicillin allergies who received cephalosporins went up from 20% to 27% in areas where the prompt was remove No difference in mortality or no new allergies found between the two groups Reduced the use of fluoroquinolones and clindamycin in the group without the prompt References Macy E, McCormick TA, Adams JL, et al.

On the Streets #10: IO Administration Gone Awry

Contributor: Aaron Lessen, MD Educational Pearls: Insulin pumps provide a continuous infusion of fast-acting insulin using a basal rate and bolus prior to meals Some connect to a continuous glucometer but often blood glucose needs to be checked manually Hypoglycemia is rarely due to a malfunctioning pump - there is usually an another external factor Hyperglycemia can be caused by underdosing, illness, pump malfunction or expired insulin The pump can be used to give a bolus of insulin in the emergency department if necessary Stopping the  device can be done manually on the device or disconnecting it from the tubing attachment - do not remove the tubing from the skin site if possible References Nimri R, Nir J, Phillip M.
