A cold, cough, or fever before an operation must be reported to the department that is treating you. Do not decide on your own whether to cancel or proceed with the procedure: the team will assess the nature of your symptoms, the planned anesthesia, the urgency of the procedure, and your overall health.
An isolated runny nose does not have the same significance as a productive cough, difficulty breathing, or a significant deterioration in general health. Therefore, the decision is not based solely on temperature or the number of days required. Call the number indicated on your appointment letter or outpatient passport as soon as possible.
Fever before an operation: why take precautions before traveling?
Infection or irritation of the respiratory tract can alter anesthetic assessment. A contagious disease can also expose other patients and healthcare workers. Finally, certain symptoms may indicate a problem that needs to be investigated or treated before a scheduled procedure.
Providing early notification allows the department to arrange a consultation, request additional information, or adjust the schedule if necessary. Arriving without having reported symptoms can lead to a delayed assessment, whereas the anesthesia consultation relies on up-to-date health data.
What symptoms should be reported to the team?
Nose, throat and cough
Describe a stuffy or runny nose, sore throat, dry or productive cough, changed voice, and any difficulty breathing. Indicate whether the symptoms improve, remain stable, or worsen, without attempting to self-diagnose a cold, flu, or bronchial infection.
Fever and general condition
Report any elevated temperature, chills, unusual fatigue, body aches, diarrhea, vomiting, or loss of appetite. Note the measurement method and time, but do not take multiple measurements to obtain a reassuring reading.
Other recent changes
Also inform the staff about any suspected urinary tract infection, skin wound, rash near the surgical site, flare-up of a chronic illness, or new medication. The pre-operative checklist helps to gather these items and useful contact information.
Who exactly should I call?
First, contact the outpatient surgery unit, the inpatient ward, the surgeon's office, or the pre-operative consultation service. The appointment letter often indicates the appropriate contact method. If multiple numbers are provided, start with the one handling your upcoming admission.
The attending physician can assess any intercurrent illness, but they do not decide alone whether to proceed with the surgery. Therefore, also inform the surgical team. Outside of regular hours, follow the instructions left by the department and seek urgent medical attention if your condition requires it.
What information should I prepare for the call?
- Your identity, the scheduled date and the type of intervention.
- The day of onset and the evolution of symptoms.
- The presence of cough, respiratory discomfort, moderate fever or digestive problems.
- Tests, consultations or treatments started since pre-admission.
- Your respiratory, cardiac or other known factors.
Answer precisely, without minimizing or exaggerating. If you took fever reducer, syrup, decongestant, or antibiotic, state its name and the exact date of administration. Do not add any new medications simply to "save" the surgery date.
Keep your test results or consultation report if possible, but do not send health data via an unauthorized email address. The service will direct you to the appropriate channel.

Who decides whether to maintain or postpone?
The decision rests with the medical team, based on the expected benefit of the procedure, its degree of urgency, your symptoms, any tests you may have undergone, and the planned anesthetic technique. A non-urgent operation can sometimes be postponed; other situations warrant proceeding with a tailored approach.
A postponement is neither a sanction nor proof of a serious complication. It aims to allow for intervention under better conditions. Conversely, a perceived improvement is not sufficient on its own to confirm that everything can proceed as planned.
Should I continue fasting and taking the medication?
Until the department gives you further instructions, follow the most recent written guidelines. Do not break your fast before anesthesia because you think the operation will be postponed, and do not extend it beyond what has been requested.
Do not change any usual or newly prescribed treatment without consulting a doctor. Some over-the-counter medications can interact with other treatments or mask symptoms. Ask for instructions on how to manage each product on the scheduled day.
What should I do if the symptoms appear that same morning?
Call before you leave if possible. If you are already en route or have arrived, immediately inform reception and the healthcare professional who greets you. Wear a mask if required by the department and follow the hygiene guidelines provided, without concealing any symptoms to avoid delays.
Do not drive if you feel weak, dizzy, or very ill. Your designated companion can help relay information. In the surgical process , same-day reassessment is part of the safety protocol.
When should you seek urgent help?
Call 15 (SAMU) in France, or 112 from any European country, if you experience significant difficulty breathing, chest pain, dizziness, confusion, bluish lips, or any other sign of distress. Mention your scheduled procedure and any medications you are taking, but do not delay calling to contact the receptionist first.
A fever after surgery indicates a different situation: consult the guide on fever after an operation while following the discharge instructions. Before the procedure, the best course of action is to inform the department.
F.A.Q
Does a simple cold always lead to a postponement?
No. The decision depends on the symptoms, the procedure, the anesthesia, and your overall health. The absence of fever does not mean you shouldn't call if your cough, breathing, or general condition has changed.
Can I take medication to lower the fever?
Seek advice from your healthcare provider and report any medication taken to the team. Do not combine products with different names but containing the same active ingredient, and do not mask a fever before your assessment.

To remember
A cold, cough, fever, or recent illness must be reported before surgery. Prepare the date of onset, its progression, and any treatments received. Continue following the instructions you have received until further notice and allow the team to decide whether to proceed, conduct a further evaluation, or postpone the surgery.
