[Preoperative analysis of vital lung capacity in female patients with flattened thyrotoxicosis]

Unbalanced hyperthyroidism leads to the feeling of dyspnea and to the decrease of vital lung capacity. Efficacious treatment of thyrotoxicosis relieves mentioned disorders and brings normalization of ventilation parameters. The main issue of this research was the analysis of vital lung capacity in female patients with properly treated hyperthyroidism and comparison of values of these parameters among patients with balanced thyrotoxicosis, non-toxic goitre and with non-thyroid disorders. Research was conducted on 300 randomized female-patients (ASA I, II), aged 18 to 47 with surgically treated hyperthyroidism, non-toxic goitre or non-thyroid disorders. Vital lung capacity (VLC) was analyzed as absolute values and as a percent of predicted values. Statistical analysis revealed that patients in specified groups did not differ in age, weight and frequency of belonging to both ASA categories. Vital lung capacity and percent of predicted values were not significantly different in all groups. Vital lung capacity of female-patients with balanced hyperthyroidism did not differ significantly from vital lung capacity of patients with non-toxic goitre and non-thyroid disorders.
