Lactate in the emergency department: a case-based critical reflection.
1Emergency department, Heart of England NHS Foundation Trust, Birmingham.
Summary
Serum lactate testing is common for undifferentiated emergency department patients. This analysis emphasizes interpreting lactate levels alongside clinical presentation, not in isolation, for accurate diagnosis.
Area of Science:
- Emergency Medicine
- Clinical Diagnostics
- Biochemistry
Background:
- Serum lactate measurements are routine in emergency departments for patients with unclear conditions.
- Elevated lactate levels can indicate various critical issues, necessitating careful interpretation.
Purpose of the Study:
- To critically analyze the utility of serum lactate testing in undifferentiated emergency department patients.
- To review the indications for lactate measurement and common causes of elevated levels.
Main Methods:
- Case-based reflection on clinical scenarios.
- Critical analysis of diagnostic rationale and interpretation of lactate levels.
Main Results:
- Lactate testing is a valuable tool but requires contextualization.
- Raised lactate levels have multiple potential etiologies beyond hypoperfusion.
Conclusions:
- Clinicians must integrate lactate results with the overall clinical picture.
- Avoid diagnosing solely based on lactate levels; consider the patient's presentation holistically.

Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
