뇌실내 출혈의 치료에 있어 뇌실도관법에 대한 고찰 = The effect of constant ventricular drainage for the patients of intraventricular hemorrhage

다국어 초록 (Multilingual Abstract)

Among all of the cerebrovascular problems that which has the highest mortality and worst prognosis is the problem of intraventricular hemorrhage. The mortality is highest immediately following the hemorrhage.
Because direct surgical intervention is thought to be very dangerous in patients with intraventricular hemorrhage most of these patients have been treated conservatively.
This study gives the results of evacuation of the intraventricular blood plus the placement of external drainage catheters which decrease the intraventricular pressure and provide an outlet for the blood should the patient have further hemorrhage. Such a procedure is associated with clinical improvement which better prepares such patients for subsequent surgical treatment.
Eighteen patients who had intraventricular hemorrhage between June 1973 and April 1974 are analyzed as to the results of this operative treatment. Also the literature concerning this new method is reviewed.
The operative procedure was as follows:
Under local anesthesia using 1% procaine unilateral or bilateral burr holes were made in the frontal area. Ventriculostomy was made through these holes. The ventricle was irrigated with physiologic sa??e removing the hematoma or the bloody ventricular fluid.
The irrigation was continued until the fluid became relatively clear. Following the initial irrigation, the cannular was removed and a Nelaton catheter placed into the ventricle. The catheter was fixed to the scalp and connected to a drainage bottle under aseptic conditions. The ventricular drainage was maintained at 200㎜H₂O for 7-10 days.
Prior to surgery 2 million units of procaine penicillin was injected into the ventricle. Pest??peratively, 5㎎ of Gentamycin was injected through the catheter twice a day.
Surgical drainage of the ventricle was done 3 hours to 7 days after the onset of clinical signs of hemorrhage. The external ventricular drainage was maintained for an average of 7.0 days.
Results:
10 patients(56%) improved and could be discharged. 4 died of recurrent intraventricular hemorrhage, of gastrointestinal bleeding, or of myocardial infarction during hospitalization.
However, all of these 4 patients showed some clinical improvement following the operative procedure. Only "4'patients expired after surgery- This mortality. of 44% is considerably less than the usually found mortality of 80-100% for intraventricular hemorrhage and 60-70% in subarachnoid hemorrhage.
On the basis of this study a mere active treatment of patients with intraventricular hemorrhage. including operative drainage of the ventricles is proposed.
