I often encounter patients online who ask for information about surgery. The most frequently asked question is how much does the surgery cost? Do I need to be hospitalized? Do I need to remove stitches? Will it leave scars? And so on. However, few people ask about the management of post-operative complications, what to do if there is a recurrence? What should I do if the scar is severe? How can I recover from difficulty in upper limb elevation? We understand the patient’s mentality. Everyone thinks good before surgery and wants everything to go smoothly, and no one wants to be so unlucky to have postoperative complications. However, for doctors, the prevention and treatment of postoperative complications is a very important part of the whole treatment process, which really tests the clinical level and mentality of doctors. Recently, I had a patient with a postoperative delayed axillary hematoma. Although the surgery was perfect and the wound looked normal when I changed the patient’s medication for the second time on the fifth day after surgery, the patient woke up the next morning with a feeling of axillary hematoma. However, the next morning the patient woke up with unbearable axillary pain. As a result, the patient’s mother noticed a small bulge in the right armpit. The patient’s mother noticed a small bulge in her right armpit. I basically decided it was a hematoma and arrived at the hospital an hour later, and the small bag I saw on the photo had turned into a large one, so without further ado. I went into the operating room to clear the wound, open it to remove a large amount of blood clots, repeatedly rinse it to find the bleeding point to stop the bleeding, then suture the wound again, and put pressure on the axillary bandage. The whole process took more than an hour, and the little girl was strong enough to persevere. Thanks to the active cooperation of the patient and her family after the operation, as well as the fine dressing changes and wound treatment, the patient’s wound basically healed one month after the operation, 5-7 days later than the normal healing time. 3 months later I reviewed the wound, and cosmetically it was no different from a normal recovering wound. This is the first time I’ve encountered such a “large and late” hematoma (I won’t put a photo of it in order to take care of the readers’ feelings) since I performed the armpit surgery. Not to mention that it was entrusted to others, face is still embarrassed, in the face of such complications, how to give patients the most appropriate and timely treatment, is the problem that I should repeatedly think about. In this process, we also benefited from the support and help of our team. After all, there is still controversy about the treatment of the flap after hematoma removal, should the flap that is completely free and darker by the hematoma topping up be removed? How to ensure unobstructed drainage? In order to avoid further blood and fluid accumulation, most of the flap would have to be removed, which would result in an unsightly scar even after healing, similar to the original flap removal surgery, which would not be aesthetically pleasing. So at that time I decided to keep the flap intact, although this risked infection and hematoma. After the surgery, through team discussion, they approved my treatment. Frankly, I had not looked into the issue of delayed hematoma very seriously before, but this encounter forced me to review the relevant literature and summarize my experience after combining this surgery and the patient’s situation. The causes of delayed hematoma are generally: 1. incomplete intraoperative hemostasis; 2. frequent vigorous postoperative activity of the patient’s upper limbs; 3. rebound delayed hematoma caused by intraoperative epinephrine use; and 3. others are thought to be related to menstrual flow. Combined with the patient’s delayed hematoma on postoperative day 5 we still agreed that it was caused by frequent postoperative activity of the upper extremity. However, we thought we had reached a conclusion and the patient was recovering well, so was the matter over? Why did the patient move his upper extremity? That is the real question that should be asked. Our axillary compression dressing method has undergone many improvements, from the earliest wire packing to oiling to the current gauze stuffing process, gradually evolving the dressing method to promote a tighter skin fit, and secondly, the dressing time has been shortened from 7-10 days to 2 days now. However, the patient still has many inconveniences during these two days, such as itchy skin allergy caused by the bandage, the upper limbs are firmly fixed in one position and cannot be moved, and the cooking of life, including sleep, is affected, we have tried to reduce the amount of gauze stuffing and the duration of the bandage. But could it be less? Could it be shorter? We might even invent a pressure pack specifically for the axilla. Nowadays, people are more and more concerned about the post-operative experience of disease treatment. The old principle that the outcome of treatment overrides all feelings has been shaken. In an interview, BJ Lee, president of United Family Healthcare, said: “Doctors in the system today are so overburdened with work that they rarely have the time to plan for post-operative follow-ups on patients’ recovery and feelings. It is difficult to give the best experience in every detail of treatment. This is the key to the success of this famous medical brand. In today’s society, more and more people are suffering from fomo syndrome (Fearing of missing one). I am one of those people who, for fear of missing crucial information, voraciously take in a lot of information that is not relevant to them. Gradually, I lost myself in the processing of this information. In the face of the current plethora of treatment modalities, I think it is the spirit we need to sink our teeth into one of them and strive to achieve the best in every detail. Medicine is a science that is evolving at a rapid pace, and without refinement, resting on the status quo will quickly drown in the dust. We are very concerned about the methods and results of surgery, not to mention the post-operative complications and their management. Just like excellent brand products must have timely and accurate after-sales service. Surgeons understand: to be able to handle various complications calmly and calmly is to be called a true master. And in this road we have a long way to go, we must hold the mentality of stay hungry stay foolish to face every problem. Good communication is important, but for the patient, the solution is the key. Finally, I am grateful that in today’s poor medical environment there is still such a patient, who did not complain to the doctor throughout the treatment process, but was fully cooperative. I believe she can also appreciate the doctor’s dedication and best efforts. And that is enough.
