Skillful Use Of Negative Pressure Drainage Device

Cranioplasty is a commonly used neurosurgery operation to fill and repair the skull defects. With the rapid development of medical science in recent years, the skull repair materials have also undergone fundamental changes. The repair materials have experienced the application process from human ectopic bone, animal bone, organic glass, silicone rubber, bone cement, stainless steel wire mesh, titanium mesh, etc. to computer molded titanium mesh. In recent years, our department has successfully carried out dozens of skull repair operations, without any failure or infection of implants, which has been praised by the majority of patients. However, we should also see our shortcomings, especially in previous operations, which have more or less postoperative fluid accumulation, extending the recovery time of patients. This year, our department improved this operation, changing the method of using drainage strips or ventricular drainer after the previous operation to that of using negative pressure drainer. Through the observation of nearly ten patients after the operation this year, no one had postoperative fluid accumulation, we fully affirmed the role of negative pressure drainer in skull repair, and should continue to promote its application in future work.

The operation of skull repair is to peel the scalp and conduct it outside the new dura. After the scalp is sutured, the repair is inlaid or the defect is covered. After the scalp is sutured, the whole cavity is closed. After partial drainage, the pressure of its contents is reduced. A simple drainage tube or drainage strip cannot drain the residual fluid, while a negative pressure drainage device can. After the drainage fluid is completely drained, the tissues on both sides of the repair can adhere to each other, It can promote wound healing and reduce postoperative fever reaction of patients, and its effect is superior to other drainage methods. This method can also keep the incision dry, reduce the number of dressing changes and the chance of incision infection. At present, our department is not only applying the negative pressure drainage device after skull repair, but also actively exploring a deeper and broader application in various craniocerebral operations, such as the application of negative pressure drainage of acute epidural hematoma, the use of double hole drainage and negative pressure suction in the treatment of chronic subdural hematoma, etc., which has achieved some good results, but still needs to continue to be observed and explored in clinical practice.
