Table 1 Temporal analysis of ICP and EEG worsening related to ICP increase, vasospasm and CT scan ischaemic evidencea
From: Dynamic monitors of brain function: a new target in neurointensive care unit
Event | Number of patients | Stable SEPs | SEPs decrease before ICP increase | SEPs decrease after ICP increase | Number of vasospasms | Epileptiform discharge (periodic discharges, rhythmic delta activity, spike wave or sharp wave) | Increase in ICP > 25 mmHg | CT scan secondary damage |
|---|---|---|---|---|---|---|---|---|
SAH, n (%) | 51 (75%) | 35 (68.6%) | 16 (31.4%) | 0 | 16 (31.4%) | 18 (35.2%) | 27 (52.9%) | 18 ischaemic lesions |
ICH, n (%) | 17 (25%) | 13 (76,5%) | 0 | 4 (23.5%) | 0 | 6 (40%) | 12 (70.5%) | 12 mass effects |
Total, n (%) | 68 (100%) | 48 (70.6%) | 16 (23.5%) | 4 (5.9%) | 18 (26.4%) | 24 (35.2%) | 39 (57.3%) | 30 (48.5%) |
