Clinical Outcomes After Traumatic Brain Injury and Exposure to Extracranial Surgery: A TRACK-TBI Study.
Roberts et al., JAMA Surg 2023
DOI: 10.1001/jamasurg.2023.6374
New Insights:
The study provides evidence that exposure to extracranial (EC) surgery and anesthesia after traumatic brain injury (TBI) is associated with worse functional and cognitive outcomes. This is significant as it suggests that secondary insults such as surgery can exacerbate the consequences of TBI.
Importance:
Understanding the relationship between surgery after TBI and subsequent outcomes is crucial for clinical decision-making. It could influence the timing and management of surgical interventions in TBI patients to minimize additional harm.
Contribution to Literature:
Previous research has shown that TBI can lead to long-term deficits, but the impact of post-TBI surgery on these outcomes was not well understood. This study adds to the literature by quantifying the negative effects of EC surgery on functional and cognitive recovery in TBI patients.
Results Summary:
– The study included 1835 participants (mean age 42.2, 70% male).
– Participants who underwent EC surgery had significantly worse functional outcomes (GOSE-ALL scores) at 2 weeks and 6 months post-injury.
– At 6 months, those with moderate to severe TBI (m/sTBI) and complicated mild TBI (CT+ mTBI) who had EC surgery showed worse brain injury-specific functional outcomes (GOSE-TBI scores: m/sTBI B = -1.11, CT+ mTBI B = -0.39).
– The same groups performed worse on the Trail Making Test Part B, indicating impaired executive function (m/sTBI B = 30.1, CT+ mTBI B = 26.3).
The findings highlight the need for further research into the mechanisms behind these associations and the potential need to adjust surgical care for TBI patients.
