Clinically Validated Emergency Medicine Scores
In the high-pressure environment of the Emergency Department (ED), rapid and standardized decision support rules save lives. Clinical calculators aid ER physicians, trauma teams, and advanced practitioners in standardizing critical care risk, optimizing resuscitation fluid volumes, predicting imaging necessity, and executing protocolized bedside assessments.
Primary ER Calculators
Our ER toolkit includes calculations essential for immediate bedside evaluation:
- Glasgow Coma Scale (GCS): Standardizes assessment of acute neurological impairment, consciousness levels, and trauma severity.
- Pulmonary Embolism (PE) Stratification: Utilizes Wells Score for PE and the Revised Geneva Score to establish diagnostic pretest probabilities.
- Bedside Trauma & Burn Scaling: Employs Parkland Formula and TBSA calculations (Rule of Nines) to guide aggressive, standardized crystalloid resuscitation.
- Orthopedic X-ray Rules: Integrates Ottawa Ankle, Foot, and Knee Rules to safely rule out fractures and minimize unnecessary radiation exposure.
- Pediatric Head Trauma Support: Features PECARN criteria to stratify minor head injury CT imaging necessity in infants and children.
BEDSIDE FAQs
PECARN provides highly sensitive, age-stratified criteria (under 2 years and 2-18 years) to identify children at extremely low risk for clinically important brain injuries. Patients meeting these criteria can be safely observed without undergoing ionizing radiation CT head scans.
The Parkland Formula calculates total 24-hour resuscitation volume as: $4 \text{ mL} \times \text{Weight (kg)} \times \text{\% TBSA burned}$. Standard guidelines dictate administering **50% of this total volume over the first 8 hours** post-injury, and the remaining 50% over the next 16 hours.
