The number of dressing changes after drainage of boils needs to be decided according to the size of the boil and whether the patient has any underlying diseases, with a fewer number of dressing changes ranging from 5 to 7 and a larger number of dressing changes ranging from at least 10.
If the boil is relatively small and the pus cavity is small, usually 5~7 times of dressing change can be recovered. If the pus cavity is relatively large and there is a lot of pus, change the medicine once a day, and change the medicine every other day after the pus is less, and it takes at least about 10 times to recover.
If the boil is combined with diabetes mellitus, hypoproteinemia or anemia, and the resistance is low, the boil will take a long time to recover from repeated episodes, and in some cases, it will take about 2 weeks. In addition to dressing changes, oral anti-inflammatory medications such as roxithromycin capsules should be taken, and subcutaneous insulin injections should be given to control blood sugar if it is high.
The dressing change after the boil is drained depends on the amount of pus and the size of the pus cavity. Careful care should be taken to control the infection and drain the boil thoroughly to prevent it from recurring.
