OBESE, ATELECTASIS
The major limitation of the present study is that while the sample size and expressive power of our study are sufficient, it is important to note that this study was conducted on a singular type of surgery and a specific patient group. Further studies will need to include larger series and more diverse patient groups; for example, obese patients, patients with severe cardiopulmonary problems, the pediatric age group, and patients undergoing different types of surgery. Another limitation is that ultrasonography was used for the diagnosis of atelectasis only in the postoperative period, whereas frequent intraoperative measurements of LUS score may detect atelectasis accurately.
