1, if the adhesions are extensive, never ask for a heart cut and expect to get it done at once, it may be better to carry out the separation in stages. Because the speed of mucosal epithelial spreading growth is basically fixed, the figure is about 0, 5mm/day. If you separate a large area of adhesions at one time, there is little chance that the center of the endometrial defect will be covered by the proliferating endometrium and will easily re-adhere. This will cause you to have to separate again, and the more times you operate, the more damage will be done. What about splitting, you can ensure that the separated part is covered by new endometrial cells, so that you can expect the endometrium at the separation to recover completely and again hysteroscopically separate the adhesions above it, so that gradually the endometrium grows full of the uterine cavity in stages; 2. The period of adhesion formation is 7-10 days after surgery, so it is better to perform a simple probe separation at this time; 3. If there is much bleeding after surgery, place a balloon catheter for 3 days. If you have a lot of bleeding, place a simple probe for 3 days to separate the adhesions; 3. If you have a lot of bleeding, place a balloon catheter for 3 days to prevent adhesions, remove the balloon catheter and then place a uterine ring; 4. Infection is certainly beneficial, once the uterine cavity is infected, more likely to occur adhesions.
