Noninvasive evaluation of intracranial pressure in patients with traumatic brain injury by transcranial Doppler ultrasound.

Introduction: The purpose of this study was to investigate the relationship between pulsatility index (PI) or optic nerve sheath diameter (ONSD) and intracranial pressure (ICP) in patients with traumatic brain injury (TBI), and the ability of ONSD and ICP to predict intracranial hypertension.

Methods: A total of 68 patients with TBI were included in this retrospective study. After receiving surgery treatment, they underwent transcranial Doppler ultrasound (TCD).

Risk Factors and Neurologic Outcomes in Patients with Traumatic Brain Injury and Coagulopathy Within 72 h After Surgery.

Objective: The purpose of this study was to explore the effect of coagulopathy in patients with traumatic brain injury (TBI) during the early postoperative period.

Methods: The baseline characteristics, intraoperative management, and follow-up data of 462 patients with TBI between January 2015 and June 2019 were collected and retrospectively analyzed by multivariate logistic regression. Coagulopathy was defined as activated partial thromboplastin time > 40 s, international normalized ratio > 1.
