6) Pregnancy Calculator: calculates the important dates for pregnant patients. Quantitative Beta HCG ranges are also included.

Whether you know the either the 1st Day LMP, the number of weeks pregnant, or due date, this module will quickly calculate the other two. For example if your patient told you their 1st Day LMP, by entering that date you will be told the number of weeks currently pregnant and the due date, plus the expected B-HCG range. Simply play with this module as it is self explanatory.

7) RSI Wizard: provides information and calculations on dosing of drugs for intubation for both adult and pediatric patients.

Head Injury Example: A head injured male weighing 70 kgs arrives at ER with diminished mental status. The decision is made that he should be intubated prior to head CT. There is papilledema on a fundoscopic exam so both Lidocaine and Mannitol are desired as adjuncts, Versed for sedative, Morphine for Narcotic, and Succinylcholine for paralytic.
Select RSI Wizard, then enter 70, select Kilograms and press ‘Enter’.Select Lidocaine & Mannitol from the Adjunct menu
Select Versed (Midazolam) from Sedation
Select Morphine from Narcotic
Select Succinylcholine from the Paralytic menu
Select the ‘Result’ button.The results page displays both the standard dosing range for both mL of drug and the mg amount. Importantly, if your patient is a child the results also recommend the Broselow Drawer by the color, along with estimated tube size for everything from ET Tube to urinary catheter size. E.g. 20 kg:
"Tube Size Info: Color Code = Blue; ETT 5.0-5.5; Laryngoscope: 2 Miller/Mac; Stylet: 14 French, ETT Depth Insertion 15-16.5 cm, LMA 2.5 Max air in cuff = 14ml, Suction Cath: 10 French, IV Cath: 18-20, Butterfly: 21-23, NG Tube: 12-14 French, Urine Cath: 10-12 French, Chest Tube 24-32 French."

This module makes a stressful situation less stressful, allowing more focus on patient care rather than spending precious time calculating drug doses.

 


8) Toxicology:
provides information on most common poisonings with the ability to calculate antidote dosing, plus provides all local poison center numbers throughout the United States.
Antifreeze Poisoning Example: An 8-year-old weighing 34 kg presents with his mother 2 hours after drinking approximately 8 ounces of antifreeze.
Select Toxicology, and then select the Poisoning/Ingestions/Bites section.
Select Ethylene Glycol (Antifreeze).
The most pertinent information is then provided including mechanism of the toxicity, clinical findings, laboratory findings, recommended laboratory tests to be taken, recommended treatment/antidote detailing both oral and intravenous methods of treating this poisoning, along with useful tips and management information.
In this example, after following the recommended urine test you decide the child will require an antidote. You would note that options for treatment include Fomepizole or Ethanol. You opt for Fomepizole so would then proceed to our antidote section to calculate dosing.
Select the ‘Back’ button, then enter the Antidote sectionSelect 34 then Kilograms, then Press ‘Enter’Select Fomepizole (Antizol)The results then display the calculated result, with the standard Dosing, mixing instructions, and Infusion
instructions. In this case you would note that initial dosing should be 15 mg/kg, followed by 10mg/kg q12 hrs x 4 doses, then 15mg/kg q12 hrs. This should be mixed 1 gram in 100mL of NS or D5W and be infused over 30 minutes IV, and should be continued until ethylene glycol levels are below 20 mg/dL.
With all poisonings you should consider consultation with your regional poisoning center for both initial and continuing management. To find the phone number of the local Poison Center, press the ‘Back’ button, then select the Phone Number section and select your state.
