“…However, small pressure variations of other origins (i.e., loud music) have also been reported as possible causes of spontaneous pneumothorax [28]. Even in studies confirming the more frequent occurrence of pneumothoraces with climatic variations, these differences are not so clear and remain controversial [19,22,23,24,26,29,30,31,32]. In our study, the average differences in the P atm between the day of the procedure and day before and after the procedure were minimal.…”

The purpose of this paper is to evaluate whether meteorological variables influence rates of pneumothorax and chest tube placement after percutaneous transthoracic needle biopsy (PTNB) of pulmonary nodules. A retrospective review of 338 consecutive PTNBs of pulmonary nodules at a single institution was performed. All procedures implemented a coaxial approach, using a 19-gauge outer guide needle for access and a 20-gauge core biopsy gun with or without a small-gauge aspiration needle for tissue sampling. Correlation between age, sex, smoking history, lesion size, meteorological variables, and frequency of complications were evaluated. Fisher exact, trend and t tests were used to evaluate the relationship between each factor and rates of pneumothorax and chest tube placement. A p value of less than 0.05 was considered to indicate a statistically significant difference. Pneumothorax occurred in 115 of 338 patients (34%). Chest tube placement was required in 30 patients (8.9%). No significant relationship was found between pneumothorax rate and age (p = 0.172), sex (p = 0.909), smoking history (p = 0.819), or lesion location (p = 0.765). The presence or absence of special weather conditions did not correlate with the rate of pneumothorax (p = 0.241) or chest tube placement (p = 0.213). The mean atmospheric temperature (p = 0.619) and degree of humidity (p = 0.858) also did not correlate with differences in the rate of pneumothorax. Finally, mean atmospheric pressure on the day of the procedure demonstrated no correlation with the rate of pneumothorax (p = 0.277) or chest tube placement (p = 0.767). In conclusion, no correlation is demonstrated between the occurrence of pneumothorax after PTNB of pulmonary nodules and the studied meteorological variables.
