Why the study?
Does preoperative VO2max predict postoperative cardiopulmonary complications in patients undergoing major pulmonary surgery?
Population
55 patients undergoing major pulmonary surgery
Comparison
Preoperative maximal oxygen uptake test < 15… vs Preoperative VO2max > 15 mL/kg/min
Design
Cohort, Investigator blinded to the preoperative assessment prospectively…
Follow-up
Postoperative period
Key result
Preoperative VO2max < 15 mL/kg/min was associated with significantly more postoperative cardiopulmonary complications following major lung resection compared to > 15 mL/kg/min (39.3% vs 0%, P<0.05).

May support VO2max <15 mL/kg/min for risk stratification before lung resection; leaves open whether testing changes management or outcomes.

Absolute Event Rate: 39.3% vs 0%
p-value: p=<0.05
Preoperative VO2max < 15 mL/kg/min significantly predicts postoperative cardiopulmonary complications following major lung resection, whereas FEV1 does not.
Bayram et al. (2007) conducted a cohort in Major pulmonary resection (n=55). Preoperative VO2max < 15 mL/kg/min vs. Preoperative VO2max > 15 mL/kg/min was evaluated on Postoperative cardiopulmonary complications (p=<0.05). Preoperative VO2max < 15 mL/kg/min was associated with significantly more postoperative cardiopulmonary complications following major lung resection compared to > 15 mL/kg/min (39.3% vs 0%, P<0.05).
