Craniocerebral trauma is a condition in which the head and brain tissue are damaged due to external forces acting on the fingers. Patients with traumatic brain injury often have complications such as consciousness disorders and intracranial hypertension, and postoperative intracranial infection is one of the more serious ones. The incidence of intracranial infection after traumatic brain injury surgery is high, the condition is critical, the mortality rate is high, and it brings great pain to patients and their families. This article will introduce the causes and treatment of intracranial infections after traumatic brain injury surgery, hoping to help you.
1、 Introduction to the causes of intracranial infection after traumatic brain injury surgery
(1) Improper surgical operation: During the surgical process, if the doctor does not strictly follow the aseptic operation procedures, it may lead to bacterial invasion into the intracranial area and cause infection.
（2） Improper postoperative care: The patient's resistance decreases after surgery, and inadequate nursing may lead to infection. Such as unclean ward environment and untimely dressing changes.
（3） Immune deficiency: Patients with traumatic brain injury often have varying degrees of immune deficiency and are susceptible to bacterial infections.
（4） Improper use of antibiotics: Overuse or overuse of antibiotics after surgery can lead to increased bacterial resistance and make infections difficult to control.
（5） Other factors such as long surgical time, significant surgical trauma, and advanced patient age may also be contributing factors to the occurrence of intracranial infections.
2、 What are the clinical manifestations of intracranial infection after traumatic brain injury surgery? (1) Fever: Postoperative patients experience high fever, with body temperature reaching 39 ℃ or above.
（2） Headache: Headaches caused by intracranial infections are often persistent and severe, often accompanied by nausea and vomiting.
（3） Consciousness disorders: Intracranial infections can cause brain tissue edema and exacerbation of inflammatory reactions, leading to consciousness disorders.
（4） Neurological symptoms: may include hemiplegia, aphasia, epilepsy, etc.
（5） Abnormal physical signs: may present with neck resistance, positive Klinefelter's sign, etc.
3、 Diagnosis of intracranial infection after traumatic brain injury surgery
(1) Medical history: It is necessary to understand the patient's history of traumatic brain injury, surgery, medication, etc.
（2） Physical examination: Observe the patient's state of consciousness, vital signs, limb mobility, etc.
（3） Laboratory examination: Conduct blood routine, C-reactive protein, cerebrospinal fluid examination, etc.
（4） Imaging examination: Check the head CT, MRI, etc. to clarify the intracranial condition and infection range.
5、 How to treat intracranial infection after traumatic brain injury surgery
(1) Anti infection treatment: Select sensitive antibiotics for treatment based on the type of pathogen and drug sensitivity test results. Such as penicillin, cephalosporins, aminoglycosides, etc. During the treatment period, it is important to closely monitor changes in the condition and adjust the type and dosage of antibiotics.
（2） Reducing intracranial pressure: Medications such as mannitol and furosemide can be used to reduce cerebral edema and improve intracranial pressure.
（3） Neuronutritional support: Pay attention to supplementing with vitamin B, ceramides and other neurotrophic drugs to promote the recovery of neurological function.
（4） Symptomatic treatment: Treat the patient's symptoms, such as cooling, antiemetic, antispasmodic and other measures, to alleviate the patient's symptoms.
（5） Surgical treatment: For serious complications such as increased intracranial pressure and hydrocephalus, surgical treatment such as ventricular drainage and shunt may be considered.
（6） Rehabilitation therapy: Rehabilitation training for patients with functional impairments can help improve their daily activity ability and quality of life.
In summary, postoperative intracranial infection after traumatic brain injury is a serious complication that requires timely diagnosis and treatment. Patients should be closely monitored for postoperative changes in their condition, and medication should be taken according to medical advice, with regular follow-up examinations. In addition, medical staff should also strengthen their awareness of aseptic operation and strictly follow nursing procedures to reduce the incidence of intracranial infections.
