Should the burn ointment be applied after the blister has burst?

Generally, burn ointment is not only applied after a blister has burst. It can be used when the blister is intact or after it has broken and been cleaned. If there's an infection, proper treatment should be performed first before applying the ointment. When in doubt, it is advisable to seek medical advice promptly. Detailed explanations are as follows:

If the burn blister remains intact without rupture and shows no signs of infection such as redness or increased pain, gently clean the wound and apply a thin layer of burn ointment. This helps protect the wound, reduce friction-related damage, moisturize the area, and promote healing. In such cases, there's no need to wait for the blister to break before using the ointment.

If the burn blister has already ruptured, remove the loose skin from the broken blister first, then clean the wound with normal saline or iodophor. Only after confirming there is no obvious exudate or pus should you apply the burn ointment. If infection occurs after the blister breaks, seek medical attention first to treat the infection. Once inflammation is under control, use the ointment as directed by a healthcare professional. Direct application without prior treatment is not recommended in infected cases.

Before applying burn ointment, ensure the wound is clean and dry. Follow the product instructions for appropriate dosage and avoid applying too thickly. After application, cover the wound with sterile gauze for protection. If redness, swelling, pain worsens, or exudate increases after using the ointment, seek medical care promptly to adjust the wound management plan.
