What labs are in a trauma panel?
The “trauma panel” usually consists of some constellation of the following studies: a complete blood count (CBC), electrolytes, BUN, creatinine, amylase, protime (PT), prothrombin time (PTT), blood type and screen (T&S) or type and crossmatch (T&C), urinalysis (UA), ethanol level, urine toxicology screen, arterial …
What is the most important lab sample to obtain on any patient with a traumatic injury?
Overall, lactate appears to correlate more accurately with traumatic mortality than base deficit alone. For acute care providers of trauma patients, lactate should also be part of the standard laboratory evaluation of individuals deemed to be at risk for serious injury requiring hospitalization.
What are therapeutic lab values?
Electrolytes
| Lab values | Normal range |
|---|---|
| Sodium | 135-145mEq/L |
| Potassium | 3.5-5.0mEq/L |
| Calcium | 8.5-10.5mg/dl |
| Magnesium | 1.7 to 2.2mg/dl |
How do you trend lab values?
To trend results:
- Make sure Select similar is enabled.
- Select the test or component you want to trend.
- Click the Trend button.
- Click the trended component in the Lab Trended view to display the graph view of the trended data.
What is included in Rainbow Labs?
Clinical laboratories often receive extra blood tubes beyond what is needed for associated laboratory test orders. Sometimes, this practice involves drawing tubes of every possible color (the “rainbow”) to allow for add-on testing at a later time.
What laboratory value would be most useful to evaluate in a patient with suspected internal hemorrhage?
Arterial blood gas may the most important laboratory value in the patient in severe shock. Acidosis is the best indicator in early shock of ongoing oxygen imbalance at the tissue level. A blood gas with a pH of 7.30-7.35 is abnormal but tolerable in the acute setting.
What is a gold top tube blood test?
Gold Top (Serum Separator, “SST”) Contains separating gel and clot activator. 6.0 mL. Most chemistry, endocrine and serology tests, including Hepatitis and HIV.
What is Rainbow extra panel?
There is a perception that ED patients will typically require additional or follow-up testing, so drawing these extra tubes prevents the need for a second blood draw. Thus, when laboratory phlebotomists receive an order for testing, they end up drawing a rainbow of extra colored tubes during the initial blood draw.
Why are laboratory studies important for trauma patients?
Resources that assist with identification of injuries or assessment of resuscitation are valuable aids to the ED physician and may help guide diagnostic and treatment options. Laboratory studies are a resource routinely utilized on trauma patients, but their value and benefit depend on the patient and clinical scenario.
How is lactate level related to patient mortality?
In a mixed population of trauma and non-trauma patients admitted to a surgical intensive care unit, Husain et al found that initial lactate level correlated well with patient mortality in contrast to initial base deficit, which did not. In addition, clearance of lactate within 24 hours was associated with a 10% incidence of mortality.
Which is the most sensitive indicator of liver injury?
Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) leak from damaged cells; thus, these enzymes are sensitive indicators of liver injury. Markedly high values (> 500 IU/L; normal, ≤ 40 IU/L), which indicate acute hepatocellular necrosis or injury, usually result from the following:
What are the diagnostic criteria for acute kidney injury?
Diagnostic criteria for AKI: AKI is defined as any of the following: • Increase in serum creatinine by ≥0.3 mg/dl (≥26.5 μmol/l) within 48 h; or • Increase in serum creatinine to ≥1.5 times baseline, which is known or presumed to have occurred within the prior 7 days; or • Urine volume <0.5 ml/kg/h for 6 h. AKI staging system: AKI stage
