Ultrasound for Postop Lung Issues in Low-Flow Anesthesia

NCT06824506 | Recruiting

• 1 other identifier: SanatoryumEAH-AK-01
• Study Type: observational
• Target: 110

Brief Summary

Detecting possible atelectasis and other respiratory problems that may develop immediately after extubation via lung ultrasonography can reduce pulmonary complications by performing necessary interventions such as oxygen support, respiratory exercises, mobilization, and non-invasive mechanical ventilation applications at an early stage. In addition, although low-flow anesthesia is frequently used in daily anesthesia practice, publications showing the effects of its use in laparoscopic cholecystectomy operations on pulmonary complications are limited. On this occasion, this study can be presented as a contribution to the literature.

Conditions

Atelectasis, Postoperative; Cholecystitis; Gallstone; Pulmonary Atelectasis

Keywords

lung ultrasound; low flow anesthesia; laparoscopic cholecystectomy

Outcome Measures

Primary Outcomes (1)

• incidence of postoperative atelectasis

  Incidence of postoperative atelectasis determined by lung ultrasonography in patients undergoing laparoscopic cholecystectomy with low-flow anesthesia

  1 hour peroperatively

Secondary Outcomes (1)

• incidence of other postoperative pulmonary complications

  1 hour peroperatively

Study Arms (1)

Low-Flow Anesthesia Group

As this study is observational in nature, no interventions will be performed by the research team. The study will involve a single group, within which the incidence and prevalence of the outcomes will be assessed.

Other: No-intervention

Interventions

No-intervention OTHER

No interventions will be performed by the research team.

Low-Flow Anesthesia Group

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

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.

You may qualify if:

• Patients with informed consent
• Patients scheduled for laparoscopic cholecystectomy
• Patients with a Body Mass Index between 18-35 kg/m²
• Patients in the American Society of Anesthesiologist (ASA) 1-2-3 category

You may not qualify if:

• Patients with emergency surgery planned
• Patients with ASA 4 and above
• Patients with lung disease
• Patients who have undergone thoracic surgery
• Pregnancy
• Patients with a preoperative Lung Ultrasound Score of 2 or 3 in any lung region
