Short term effects of scoliosis surgery on lung function
Wilcoxon signed rank test was used to compare LFT results prior to and
after surgery in 43 patients. No significant change was observed of
absolute values of (F)VC, FEV1/FVC and PEF prior to
surgery compared to 3-4 months after surgery (table 2). Standardized
values of (F)VC and PEF were significantly lower 3-4 months after
surgery compared to results before surgery. Subgroup analysis in
patients with NMDs showed similar results.
