Background:
The potential effect of intraoperative factors on respiratory complications after pneumonectomy is still unclear.
Methods:
We conducted a retrospective cohort study; charts of 129 patients who underwent elective pneumonectomy at the University of Virginia were reviewed. Logistic regression was used to estimate the effect of anesthetic factors on the odds of at least one respiratory complication. Linear regression models were fit to assess the impact of these outcomes on length of stay (LOS).
Results:
The incidence of respiratory complications in this cohort was 21%. In univariate analysis total nonblood fluids (p = 0.001), and the blood products packed red blood cells (p < 0.001), plasma (p < 0.001), and platelets (p = 0.044) were significantly associated with respiratory complications. In a multivariable logistic regression analysis, single unit transfusion of any blood product (packed red blood cells, plasma, or platelets) was identified as a major risk factor for respiratory complications after controlling for covariates (odds ratio = 1.47, 95% confidence interval 1.06 to 2.05). Respiratory failure and complications were closely related to LOS, increasing the LOS by a factor of 4.7 (95% confidence interval 3.51 to 6.18) and 3.5 (95% confidence interval 2.69 to 4.41), respectively.
Conclusions:
Blood product transfusion affects respiratory function and is an independent risk factor for respiratory complications after pneumonectomy.

Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
