Why the study?
Intraoperative hypotension during surgery is common and linked to adverse outcomes, but lacks universally agreed standards for defining hypotension values or consensus on interventions.
In pediatric scoliosis surgery, defining intraoperative hypotension as a mean arterial pressure less than 60 mmHg correlates significantly with the clinical decision to administer ephedrine.
No takes yet. Share an insight, caveat, or question.
Different hypotension definitions correlated in pediatric scoliosis surgery; leaves open standardization of thresholds before guiding practice.
Santana et al. (2020) studied this question.
