Combination effects of invasive intracranial pressure and transcranial Doppler monitoring in treatment of posttraumatic acute diffuse brain swelling / 中华创伤杂志

ABSTRACT

Objective To investigate the combined effects of invasive intracranial pressure and transcranial Doppler (TCD) monitoring in the treatment for posttraumatic acute diffuse brain swelling (PADBS).Methods The clinical data of 120 patients with PADBS admitted from January 2014 to January 2016 were retrospectively analyzed by case-control study.There were 88 males and 32 females,aged 19-70 years (mean,43.6 years).Patients were divided into three groups based on whether they had accepted invasive intracranial pressure and TCDGroup A (37 cases) with neither invasive intracranial pressure nor TCD,Group B (40 cases) with invasive intracranial pressure only,and Group C (43 cases) with both intracranial pressure and TCD.The hospitalization time in ICU,better prognosis [Glasgow outcome scale (GOS) scored 4-5] at 12 months after injury,Barthel index (BI),and mini-mental status examination (MMSE),mydriasis rate,and decreased values of Glasgow coma scale (GCS) were compared among three groups.Results (1) The ICU length of stay in the Groups of A,B and C was respective (9.6 ± 6.8) days,(9.2 ± 5.4) days and (8.9 ± 5.7) days (P ＞ 0.05).The ratio of better prognosis in the Groups of A,B and C was respective 46％ (17/37),65％ (26/40) and 72％ (31/43),showing a better result in Groups B and C than Group A (P ＜ 0.05).However,there was no significant difference in ratio of better prognosis between Groups B and C (P ＞ 0.05).The BI in the Groups of A,B and C was respective (51.0 ± 36.7) points,(58.0 ± 35.7) points and (70.2 ± 34.6) points,while the MMSE was respective (17.3 ± 12.5) points,(18.8 ± 12.0) points and (21.2 ± 11.4) points.Both BI and MMSE in Groups B and C were higher than those in Group A (P ＜ 0.05),moreover,those in Group B were also statistically lower than those in Group C (P ＜ 0.05).(2) The ratio of mydriasis from admission to initiation of operation in Groups A,B and C was respective 33％ (9/27),13％ (4/30) and 7％ (2/28),showing a higher ratio in Group A than Groups B and C (P ＜ 0.05).But there were no statistical difference in the ratio of mydriasis between Groups B and C (P ＞ 0.05).The decreased value of GCS from admission to initiation of operation in Groups A,B and C was (1.4 ± 1.3) points,(0.7 ± 0.5) points and (0.6 ± 0.4) points respectively,showing a larger decrease in Group A than Groups B and C (P ＜ 0.05).But there was no statistical difference in the decreased value of GCS between Groups B and C (P ＞ 0.05).Conclusion Application of invasive intracranial pressure and TCD monitoring can present a timely and precise condition changes,improve the better prognosis rate,daily activity abilities and cognitive function,indicating that it has protective effects on the brain function.
