“That Alkaline Phosphatase Seems Really High…”

Today at Morning Report we talked about how to approach a patient with an elevated alkaline phosphatase. There’s a fantastic review article from Clinical Liver Disease by Dr. Siddique and Dr. Kowdley from Virginia Mason Medical Center about how to evaluate and work up a patient who presents with an abnormally high alkaline phosphatase. Key points, tables, charts below from the article:

  • Highest concentration of AP is in liver and bone. But also found in intestine, kidney, and placenta.
  • It can vary with age, gender, and blood type.
  • Try to find the source of the elevated AP – fractionation of isoenzymes by electrophoresis or obtaining 5’nucleotidase and gamma glutamyl transpeptidase (GGT) levels, both of which are elevated in hepatobiliary disease
  • Determine whether cholestasis is secondary to intrahepatic or extrahepatic disease process keeping in mind some diseases can cause both such as primary sclerosing cholangitis

A New Approach in Reducing Risk of Peanut Allergy? Promising Study Released!

This week’s NEJM released a study (LEAP Trial) from King’s College in London looking at reducing the risk of developing peanut allergies in infants by having them consume peanuts. The authors observed decreased frequency of peanut allergies in the group that consumed peanuts versus the group that avoided. Dr. Rebecca Gruchalla, Professor and Director of the UT Southwestern Allergy and Immunology Division, co-wrote an editorial in the NEJM describing the trial and its potential effect on future studies and management of food-based allergies. Check out the original study and Dr. Gruchalla’s editorial below!

Rewarming in Accidental Hypothermia

REWARMING METHODS

Passive:

  1. Remove clothing
  2. Dry patient
  3. Cover with blankets / space blanket
  4. Provide warm sugary drinks

Active External:

  1. Forced Air Rewarmer (eg: Bair Hugger) ‐ to trunk only to reduce core temperature afterdrop.
  2. Arctic Sun (for moderate / severe).

Active Internal:

  1. Warmed fluids (D5 NS @ 40-42 C) – Initially 250-500mL bolus, repeat based on clinical
  2. Warm, humidified oxygen. By facemask or consider CPAP – by ETT if intubated.
  3. Peritoneal Lavage – 2 liters of diasylate @ 40 – 45 C, remove after 20-30 minutes. Rewarming rate of 1-3 C / hr.
  4. Body cavity lavage – Through Foley or NGT / OGT. 500mL boluses or continuous Consider risk of fluid / electrolyte shifts.
  5. Closed Thoracic Lavage – 2 large bore (38-40 fr) chest tubes in each hemithorax (one at mid clavicular line @ 2nd / 3rd interspace, second at post. axillary line @ 5th / 6th interspace). Infuse warmed (40-42 C) saline and drain though posterior tube.
  6. Thoracotomy with Mediastinal Lavage – 1-2 liters of warmed NS to mediastinum, remove after 1-2 minutes. May utilize cardiac massage and internal defibrillation. Highly Invasive, requires disposition to OR.

Extracorporeal:

  1. Continuous Venovenous Rewarming (CVVR) – 2-3 C / hr.
  2. Continuous Arteriovenous Rewarming (CAVR) – 3-4 C / hr. Requires adequate MAP. Can be performed in ED with proper equipment.
  3. Hemodialysis – 3-4 C / hr. Requires adequate MAP. Possible to correct electrolyte and toxic abnormalities. Requires dialysis staff.
  4. Cardiopulmonary Bypass – Most rapid rewarming (8-10 C / hr). Provides full cardiopulmonary support for hemodynamically unstable patients.
