Abstract：Objective To explore the relationship between CT measurement of optic nerve sheath diameter（ONSD）and postoperative intracranial pressure（ICP）in patients with craniocerebral trauma. Methods 60 patients with craniocerebral trauma who underwent decompressive craniectomy were selected as the research objects.Invasive ICP monitoring was implanted during the operation, and they were divided into 34 normal groups（ICP≤ 20mmHg）and 26 increased groups（ICP> 20mmHg）according to the postoperative ICP levels.All patients underwent thin-slice CT examination of the head to measure their ONSD.To analyze the relationship between ONSD and postoperative ICP in patients with craniocerebral trauma. Results ONSD of ICP group was higher than that of normal group（P< 0.05）.Pearson correlation analysis showed that ONSD was positively correlated with postoperative ICP in patients with craniocerebral trauma（P< 0.05）.Glasgow coma scale（GCS）in ICP group was lower than that in normal group（P< 0.05）.Multiple regression analysis showed that ONSD and GCS scores were the influencing factors of postoperative ICP in patients with craniocerebral trauma（P< 0.05）. Conclusion CT measurement of optic nerve sheath diameter is closely related to postoperative intracranial pressure increase in patients with craniocerebral trauma, and can be used as an important index for clinical evaluation of postoperative intracranial pressure increase in patients.
