What is the cause of craniotomy infection?

summary

Because of the high risk of craniotomy, such as the doctor's misoperation leading to brain injury, the operation itself is also controversial. However, for some special diseases, such as Parkinson's disease, epilepsy, craniotomy is still necessary. The patient has a cranial nerve injury, so the recovery time is related to the recovery of nerve tissue function, and has nothing to do with whether it is craniotomy and anesthesia. What is the cause of craniotomy infection? Let's talk about it

What is the cause of craniotomy infection?

(1) External ventricular drainage. The infection rate of external ventricular drainage was 10% ～ 17%, which occurred more than 2 weeks after operation. It is suggested that if the drainage tube cannot be removed after more than 10 days, internal drainage or intermittent lumbar puncture should be considered. The main causes of infection are bacterial retrograde infection, such as improper nursing of drainage tube and lax aseptic operation when replacing drainage bottle.

(2) The bacteria contaminated by open craniocerebral injury may be infected retrogradely through the wound, which makes the infection rate increase significantly（ 8) Long time operation under microscope will increase the risk of infection, which may be related to the wound contamination caused by the operator or assistant's inattention.

(3) Cerebrospinal fluid leakage is a high risk factor for infection. According to mollman and Haines' retrospective investigation of 9202 cases of Neurosurgery, postoperative cerebrospinal fluid leakage is a risk factor for increased infection.

matters needing attention

Strengthen the nutrition and basic nursing. The patients in this group are older, the energy consumption increases after operation, and the basal metabolism increases due to high temperature. Therefore, the nutrition should be strengthened, and those who can not eat should be given nasal feeding, so as to maintain sufficient heat and electrolyte balance and enhance the body resistance. Keep the bed flat and dry, do a good job in oral care and skin care, to prevent the occurrence of other complications.
