TRAUMATIC PNEUMOCEPHALUS : AIR REPLACEMENT PROCEDURE VS CONTROLLED DECOMPRESSION WITH EXTERNAL DRAINAGE

Introduction: Air within cranium may be classified according to the site of occurrence. The pathophysiology of the same is varied and the effects are manifold. Methods: Patients with tension pneumocephalus are taken up for surgery.Results: In controlled decompression group, the pain requirement and duration of hospital stay was more. The air replacement procedure group had more recollection and one patient required a second procedure.Conclusion: Most of the cases subside with normobaric 100% oxygen therapy. In patients with persistent pneumocephalus for more than two weeks, more definitive procedures for sealing of the dural rent may be required

Study on the effect of cerebrospinal fluid release combined with controlled decompression under intracranial pressure monitoring on prevention of intraoperative intracranial swelling in patients with acute severe craniocerebral injury / 中国医师进修杂志

Objective To explore the effect of cerebrospinal fluid release combined with controlled decompression under intracranial pressure monitoring on prevention of intraoperative intracranial swelling in patients with acute severe craniocerebral injury. Methods According to the inclusion and exclusion criteria, 90 patients with acute severe craniocerebral injury were randomly divided into study group (48 cases) and control group (42 cases). Patients in the study group underwent ventricular intracranial pressure probe placement, and then the standard decompressive craniectomy. During the operation, cerebrospinal fluid release combined with controlled decompression under intracranial pressure monitoring was applied to prevent brain swelling. Patients in the control group underwent standard decompressive craniectomy combined with controlled decompression to prevent brain swelling. The incidence of intraoperative brain swelling and cerebral infarction within 3 d after surgery, and the mortality within 1 month after surgery were evaluated. Prognosis was evaluated by GOS score after 3 months of follow-up. Results The brain swelling rate, cerebral infarction rate, mortality within 1 month, and Glasgow Coma Scale (GOS) score at 3 months after operation in the study group were better than those in the control group with statistical significance:10.4％(5/48) vs. 28.6％(12/42), 29.2％(14/48) vs. 64.3％(27/42), 18.8％(9/48) vs. 35.7％(15/42)], (2.83 ± 1.08) scores vs.(1.83 ± 0.76) scores, P<0.05. Conclusions Cerebrospinal fluid release combined with controlled decompression under intracranial pressure monitoring can reduce the incidence of intraoperative brain swelling and improve the prognosis of patients with acute severe craniocerebral injury.

Effect of hyperbaric oxygen combined with progressively controlled decompression on the prognosis of patients with emergency craniocerebral trauma / 中国基层医药

Objective To explore the effect of hyperbaric oxygen combined with progressively controlled decompression on the prognosis of patients with emergency craniocerebral trauma.Methods Ninety-six patients with emergency craniocerebral trauma were selected as study subjects,and they were divided into observation group (n =50) and control group(n =46) according to the random number table.The observation group was treated by progressively controlled decompression combined with hyperbaric oxygen,while the control group was treated by standard large trauma craniotomy combined with hyperbaric oxygen.The incidence of perioperative complications,prognosis (evaluated by GOS) and activities of daily living(evaluated by ADL) were compared between the two groups.Results In the observation group,the incidence rates of perioperative acute encephalocele,delayed hematoma and postoperative cerebral infarction were 6.0％,10.0％,6.0％,respectively,which were lower than 19.6％,26.1％,21.7％ of the control group(x2 =4.031,4.255,5.069,all P ＜ 0.05).The good prognosis rate in the observation group was 62.0％,which was significantly higher than 39.1％ in the control group (x2 =5.014,P ＜ 0.05).There was no significant difference in ADL score between the two groups before treatment (t =0.347,P ＞ 0.05).After treatment,the ADL scores of the two groups were increased (t =5.673,8.223,all P ＜ 0.05).Meanwhile,the ADL score of the observation group was higher than that of the control group (t =2.920,P ＜ 0.05).Conclusion The application of progressively controlled decompression combined with hyperbaric oxygen in patients with emergency craniocerebral trauma is conductive to reduce acute encephalocele,bone window brain tissue incarceration,delayed hematoma,postoperative cerebral infarction and other complications.Besides,it can repair the damaged nerve cells,and eventually improve activities of daily living of patients and reduce morbidity and mortality,and the prognosis is better.
