Letter to the editor: Brain tissue oxygen partial pressure monitoring and prognosis of patients with traumatic brain injury: a meta-analysis

The meta-analysis by Shen et al. in Neurosurgical Review highlights the benefits of brain tissue oxygen partial pressure (PbtO₂) monitoring in reducing mortality and intracranial pressure in severe traumatic brain injury (TBI) patients. However, it also associates PbtO₂ monitoring with prolonged hospital stays. Future research should focus on standardizing PbtO₂ protocols, integrating with advanced neuroimaging, exploring long-term outcomes, evaluating combination therapies, and conducting cost-benefit analyses. Addressing these areas could further enhance the clinical application and efficacy of PbtO₂ monitoring in improving patient outcomes.
