Blood blisters appear after the finger is pinched, which will cause local swelling, pain and discomfort, and need to be treated under the guidance of the clinician, mainly including conservative observation, puncture and aspiration, and topical drug treatment.
1. Conservative observation: small blood blisters do not require much intervention, and most of them will improve on their own as blood is gradually absorbed.
2. Puncture and aspiration: If the blood bubble is large, the absorption is slow and the symptoms are obvious, local puncture can be considered to aspirate the blood inside.
3. Topical medication: after puncture and suction, it is necessary to apply medication to the local wound to prevent infection, and commonly used medications include polymyxin B and so on.
If local infection occurs during the treatment of blood blisters, it is necessary to consult a doctor in time for observation and standardized treatment under the guidance of a clinician after confirming the specific condition.
