  1. Selected results of pulmonary function tests in both groups of patients. Spirometry was performed 1 day before surgery (admission), 1 day after surgery (POD1), and 4 days after surgery (POD4). Data are presented as means and 95% confidence intervals. P-values were calculated with Student’s t-test was. ESP – erector spinae plane, PECS – pectoralis nerve, FVC – forced vital capacity, FEV1 – forced expiratory volume in 1 s, PEF – peak expiratory flow
