Abstract:
Objective To discuss the feasibility of estimation on intracranial pressure of patients withbrain injury by measuring optic nerve sheath diameter (ONSD) with uhrasonography.Methods From July 2008 to December 2011,90 patients with brain injury were selected.According to the admission Glasgow Coma Scale (GCS),they were divided into experimental group 1 (60 cases with light and medium brain injury,GCS 9-15 scores) and experimental group 2 (30 cases with severe brain injury,G CS 3-8 scores).The conventional physical examination 50 cases and volunteers 50 cases in neural surgical outpatient were selected as control group.ONSD of all groups were measured 3 mm behind the globe through orbital by ultrasonography with different time after admission.The intracranial pressure was measured at 0.5-1.0 h after ultrasonography by lumbar vertebra puncturing in different groups and analyzed statistically.Results After admission 1,3,7,14 d; ONSD in experimental group 1 respectively was (4.49 ± 0.31),(4.45 ±0.28),(4.41 ±0.32),(4A3 ±0.25) mm;ONSD in experimental group 2 respectively was (5.69 ±0.32),(6.30 ± 0.47),(5.71 ± 0.26),(4.77 ± 0.36) mm.After admission 1,3,7,14 d ;the intracranial pressure in experimental group 1 respectively was (78 ± 16),(83 ± 17),(90 ± 15),(82 ± 14) mmH2O (1 mmH2O =0.0098 kPa) ;the intracranial pressure in experimental group 2 respectively was (230 ± 22),(269 ± 21),(228 ± 13),(147 ± 22) mumH2O.ONSD and the intracranial pressure was (4.58 ± 0.41)mm and(88 ± 10) mmH2O in control group.ONSD and the intracranial in Experimental group 1 and control group had no difference (P ＞0.05); those of control group and experimental group 2,experimental group 1 and experimental group 2 had difference (P＜ 0.05).Conclusions ONSD and the intracranial pressure in light,medium brain injury patients have no change.In patients with severe brain injury after different time,the intracranial pressure change differently,ONSD enlargement with the intracranial pressure rising,examination of ONSD by ultrasonography can reflect the changes of the intracranial pressure,it is a new method to evaluate the intracranial pressure,has the certain application value.
