Summary

This study looks at whether using lung ultrasound right after gallbladder surgery can find breathing problems like collapsed lung tissue (atelectasis) early. About 110 adults having laparoscopic gallbladder removal with low-flow anesthesia will be checked. The goal is to see if early detection helps doctors provide faster treatment, such as oxygen or breathing exercises.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

All cases that meet the inclusion and exclusion criteria will be included in the study. Patients will be taken to the operating room after being preoperatively evaluated in the observation room. The patient's anesthetic management will be provided by another anesthesiologist who is not participating in the study and is responsible for the patient. Intraoperative data will be obtained from the patient's anesthesia follow-up form and the records of the anesthesia machine. When the patients arrive in the recovery room, postoperative ultrasonographic measurements and other evaluations will be performed and noted. This group will include patients who received general anesthesia using low-flow techniques during the intraoperative period.
