Question:

Hello doctor! My 6-year-old child had a tonsillectomy and adenoidectomy about two weeks ago. A few days ago, there was an episode of bleeding from the throat that lasted for about 30 minutes. My child also had a mild fever around 38.3°C during the first week after surgery, which eventually went down.
However, starting this afternoon, a high fever of over 38.5°C began. Even after giving fever reducers, the temperature keeps spiking up to 39.2°C. The hospital originally told us to go to the emergency room if a high fever occurs after surgery, but since it has been over two weeks, I am not sure if going to the ER is still necessary.
Current symptoms include a mild runny nose and a slight cough. My child is not taking any prescription medications right now. We were recently told by a doctor that the surgical site is about 70-80% healed. Should we go to the emergency room? Is it possible that this fever is just from a different cold virus?
Answer:
Hello! I understand you must be very worried about your child's sudden high fever while recovering from a tonsillectomy.
You need to visit the emergency room immediately.
Why an ER visit is necessary right now:
Risk of infection: The combination of a recent post-operative bleeding episode and a current high fever raises significant concern for an infection.
Unresponsive fever: A high fever of 39.2°C that does not respond to fever-reducing medications requires immediate medical evaluation.
Incomplete healing: The surgical site is not yet completely healed, leaving it vulnerable to complications.
Possible causes for the fever:
Secondary infection at the surgical site: This is the most concerning possibility and needs to be ruled out or treated promptly.
Common cold or viral infection: While the runny nose and cough might suggest a standard respiratory virus, this must be clinically differentiated from surgical complications by a doctor.
Post-operative inflammatory response.
Even though your child has mild cold symptoms, the recent history of throat bleeding combined with a persistent, unresponsive high fever mandates a prompt evaluation by a medical professional. An infection at a recent bleeding site requires rapid treatment.
When you go to the ER, please remember to:
Bring your notes regarding the surgery date and the exact timing of the recent bleeding episode.
Show the medical staff your child's temperature log and the times you administered fever reducers.
Explicitly mention that you are concerned about post-tonsillectomy complications.
For your child's safety, please head to the nearest emergency room right away for an in-person assessment. I hope your child feels better and recovers quickly!
