An adverse response during treatment: the first-minute protocol

Speed during an incident does not mean rushing. The team needs a short sequence that it can repeat consistently. The most dangerous mistake is delivering “one more pulse to check” before anyone understands what happened. Stopping is not an admission of fault. It preserves the chance to assess the situation properly.

Step 1. Stop energy delivery immediately

Remove the handpiece, place the device in a safe state and prevent accidental activation. Do not continue on an adjacent area or change a setting for another test pulse. Ask the client about pain, visual symptoms, odour, heat and their general condition.

If there may be an eye injury or severe systemic symptoms, activate the emergency medical pathway. Keep protective eyewear on inside the controlled area until the device is safe. One team member attends to the client while another secures the room and communication where possible.

Step 2. Follow the local first-aid protocol

Use cooling, cleansing or other measures only as described in staff training, the device instructions and local protocol. Do not apply random ointments or place ice directly on the skin. Do not make medical promises.

Assess and mark the boundaries of the response, and take consented, time-stamped photographs. Observe changes while the next decision is arranged. Explain each action briefly and calmly without disputing the client’s sensations.

• Time and exact location of the response.
• Device model, handpiece and every parameter.
• Cooling, technique and number of passes.
• Symptoms, photographs and actions taken.

Step 3. Preserve the data before any restart

Do not clear logs or return the device to service before capturing the screen, error code and equipment condition. Preserve consumables and contact components under the internal procedure if they may matter to the investigation. Record the event time precisely.

The record must allow another qualified person to reconstruct the sequence without guessing. Use observable wording such as “redness measuring...” and “the client reported...”, not an unassessed conclusion such as “a burn caused by sensitive skin”.

Step 4. Escalate and close the loop

The responsible person decides whether the client needs emergency care, a planned medical review, a manufacturer report or equipment service. Give the client written warning signs, a contact route and a time for the next follow-up. “Keep an eye on it” is not sufficient discharge advice.

Return the device or affected handpiece to service only after formal authorisation. Review the incident without searching for a convenient culprit: what happened, which barriers worked, where documentation or training was weak, and what must change before the next client.
