Permissive hypotensive resuscitation in patients with traumatic hemorrhagic shock

We read the article "Risks and benefits of hypotensive resuscitation in patients with traumatic hemorrhagic shock: a meta-analysis" by Natthida Owattanapanich et al. with great interest and found it to be insightful. In our commentary, we propose possible reasons why mortality was lower in the permissive hypotension group and how the need for blood transfusion decreased in this group. No significant difference in acute kidney injury (AKI) was evident among patient groups, possibly because all these patients might have AKI. However, we do agree that permissive hypotension is of considerable benefit to trauma patients and worth further study.
