The morbidity and mortality from pseudomonas aeruginosa infections is high and empiric double-antibiotic coverage (DAC) is sometimes given; quality evidence for this practice is lacking.

Although there is little supporting data, the following reasons have been given for DAC:

  • DAC provides better empiric coverage through differing mechanisms of antibiotic action
  • DAC prevents the emergence of antibiotic resistance during therapy

The potential harm of antibiotic overuse cannot be ignored, however, and include adverse reaction, microbial resistance, risk of super-infection with other organisms (e.g., Clostridium difficile), and cost.

There may be a signal in the literature demonstrating a survival benefit when using DAC for patients with shock, hospital-associated pneumonia, or neutropenia. The IDSA guidelines, however, do not support DAC for neutropenia alone; only with neutropenia plus pneumonia or gram-negative bacteremia.

Bottom line: Little data supports the routine use of DAC in presumed pseudomonal infection. It may be considered in patients with shock, hospital-associated pneumonia, or neutropenia (+/- pneumonia), but consult your hospital’s antibiogram or ID consultant for local practices.

The management of alcohol withdrawal syndrome (AWS) includes supportive care focusing on the ABC’s and administration of benzodiazepines (BDZ). 

While BDZ are effective in the treatment of AWS, some patients may require very high doses of BDZ to control symptoms (tachycardia, hypertension, diaphoresis, etc.); unfortunately, high-doses of BDZ may lead to suppression of the respiratory drive and endotracheal intubation.

Dexmedetomidine (DEX) is a sedative agent that is an intravenous alpha2-agonist (it's like clonidine); it reduces sympathetic outflow from the central nervous system and it may help treat withdrawal syndromes. The major benefit of DEX is that it does not suppress the respiratory drive, thus intubation is not required.

Smaller trials and case series have shown that patients with AWS who were treated with BDZ in addition to DEX had better symptom control, lower overall BDZ doses, and less respiratory depression/intubation.

Bottom-line: While more trials are needed, consider adding DEX for patients with AWS who require high-doses of BDZ.

The pregnant patient normally has increased cardiac output and minute ventilation by the third trimester. Despite this increase, however, these patients have little cardiopulmonary reserve should they become critically-ill.

Remember the mnemonic T.O.L.D.D. for simple tips that should be done for the pregnant patient who presents critically-ill or with the potential for critical illness: 

  • Tilt: The supine-hypotension syndrome occurs after the 20th week of pregnancy as the gravid uterus compresses the IVC and aorta, reducing cardiac output by up to 30%. Placing a 30-degree right hip-wedge under the patient will relieve this obstruction.
  • Oxygen: the growing uterus pushes up on the base of the lungs reducing the functional residual capacity meaning there is less oxygen reserve and rapid oxygen desaturations. Supplemental oxygen may increase the patient's reserve.
  • Lines: The circulatory system reserve is reduced, so early and large bore venous access is important. Remember that lines should be placed above the diaphragm because the enlarging uterus compresses pelvic veins, reducing venous return to the heart.
  • Dates: Rapidly determine the gestational age of the fetus as 24 weeks is a critical date to remember (e.g., increased risk of supine-hypotension syndrome, fetal viability, etc.)
  • Delivery: Call labor and delivery early on, not only for the consultation, but also for the fetal monitoring that this service provides.

There have been so many great talks at ACEP 2013, but Dr. Michael Winters' talk "The ICU is NOT Ready for Your Patient" was chock full of great critical care pearls. Here are just a few:

  • Increased mortality for ICU patients boarding in the Emergency Department; the increase is 1.5% per each hour of delayed transfer.
  • Intubated patients should receive analgesia BEFORE sedation; fentanyl is recommended because hemodynamically stable, but you can use anything. Good analgesia will also reduce total sedative dosing
  • Use continuous capnography for the intubated patient; can detect equipment malfunction and allow titration of ventilation
  • Keep an eye out for abdominal compartment syndrome. Physical exam is not always conclusive, should obtain bladder pressures
  • Reduce the risk of ventilator-associated pneumonia by keeping endotracheal cuff pressures adequate and keeping the head of bed elevated 30-45 degrees

  • The efficacy of epinephrine during out-of hospital cardiac arrest has been questioned in recent years, especially with respect to neurologic outcomes (ref#1).

  • A recent study demonstrated both a survival and neurologic benefit to using epinephrine during in-hospital cardiac arrest when used in combination with vasopressin and methylprednisolone.

  • Researchers in Greece randomized 268 consecutive patients with in-hospital cardiac arrest to receive either epinephrine + placebo (control group; n=138) or vasopressin, epinephrine, and methylprednisolone (intervention arm; n=130)

    • Vasopressin (20 IU) was given with epinephrine each CPR cycle for the first 5 cycles; Epinephrine was given alone thereafter (if necessary)

    • Methylprednisolone (40 mg) was only given during the first CPR cycle.

    • If there was return of spontaneous circulation (ROSC) but the patient was in shock, 300 mg of methylprednisolone was given daily for up to 7 days.

  • Primary study end-points were ROSC for 20 minutes or more and survival to hospital discharge while monitoring for neurological outcome

  • The results were that patients in the intervention group had a statistically significant:

    • probability of ROSC for > 20 minutes (84% vs. 66%)

    • survival with good neurological outcomes (14% vs. 5%)

    • survival if shock was present post-ROSC (21% vs. 8%)

    • better hemodynamic parameters, less organ dysfunction, and better central venous saturation levels

  • Bottom-line: This study may present a promising new therapy for in-hospital cardiac arrest and should be strongly considered.
