Differential Diagnosis
- Single most likely diagnosis
- B. SIRS (Systemic Inflammatory Response Syndrome): The patient presents with chills, rigor, and a temperature of 38 degrees, which are indicative of an inflammatory response. The white blood cell count (WBC) is slightly elevated but still within the normal range, and other vital signs such as heart rate and blood pressure are not significantly altered, making SIRS a likely diagnosis given the recent intervention and the body's response to potential infection or inflammation.
- Other Likely diagnoses
- A. sepsis: Although the patient's WBC is within the normal range, the presence of chills, rigor, and fever post-intervention could suggest an early stage of sepsis, especially if the intervention introduced bacteria into the bloodstream. However, the lack of significant organ dysfunction or more pronounced vital sign abnormalities makes it slightly less likely than SIRS at this stage.
- C. bacteremia: The development of symptoms like chills and rigor after a medical intervention that could introduce bacteria into the bloodstream makes bacteremia a plausible diagnosis. However, without more specific evidence of bacterial infection in the blood, it's considered less likely than SIRS but still a possibility.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- D. septic shock: Although the patient's blood pressure is currently stable, and there's no mention of organ dysfunction, septic shock is a potentially deadly condition that can evolve rapidly from sepsis. It's crucial to monitor the patient closely for any signs of deterioration, such as hypotension, decreased urine output, or altered mental status, which would indicate septic shock.
- Rare diagnoses
- Other rare conditions such as an allergic reaction to a medication administered during the intervention, a non-infectious inflammatory response, or a complication unrelated to the intervention itself could be considered but are less likely given the context of recent cholangitis intervention and the symptoms presented.
