Key result
Prone positioning during elective lumbar spine surgery did not significantly alter cardiac index or other major hemodynamic parameters compared to the supine position, although central venous pressure and peak airway pressure increased.
Why the study?
Does prone positioning change hemodynamic parameters compared to supine positioning in adult patients undergoing elective lumbar-spine surgery?
Observational (n=56)
No
Does prone positioning change hemodynamic parameters compared to supine positioning in adult patients undergoing elective lumbar-spine surgery?
Prone positioning using a longitudinal bolster frame during general anesthesia for lumbar spine surgery does not significantly alter cardiac index or other major hemodynamic parameters measured by the FloTrac/EV1000 system, except for an increase in central venous pressure and peak airway pressure.
May support prone positioning without major hemodynamic impact in elective lumbar surgery; leaves open questions for higher-risk patients.
The changes in the hemodynamic parameters when the patients assumed a prone position from a supine position were examined using the FloTrac/EV1000

Jang et al. (2015) conducted an observational in Elective lumbar spine surgery (n=56). Prone position vs. Supine position was evaluated on Cardiac index (CI) (p=>0.05). Prone positioning during elective lumbar spine surgery did not significantly alter cardiac index or other major hemodynamic parameters compared to the supine position, although central venous pressure and peak airway pressure increased.
