Abstract
Need For Study Perioperative prediction of respiratory complications is important in patients undergoing laparoscopic surgeries under general
anesthesia,. Spirometry- most frequently used method for perioperative evaluation of respiratory function, but it is effort dependent. Forced
oscillation technique(FOT) overcomes this problem as it is a simple, effortless and non-invasive means of assessing the respiratory mechanics, The
technique involves external application of pressure wave to the respiratory system while the patient is breathing normally at tidal volume followed
by measurement of airow. It is capable of detecting respiratory changes due to endotracheal intubation, duration of general anesthesia and carbon
dioxide insufation both in airway (blocks, narrowing, spasms) as well as parenchyma (consolidation, atelectasis or collapse) In our study, we
intend to analyze these changes in patients undergoing laparoscopic abdominal surgeries under general anesthesia which may help in early
detection and in turn guide to decerese the incidence of respiratory complications.
Aim&objective1) To evaluate the changes in respiratory resistance and reactance in patients undergoing laparoscopic abdominal surgeries using Forced
Oscillation Technique before and after surgery.
2) To evaluate the clinical prole of patients with signicant changes.
Materials And Methods- This is a ongoing prospective-observational study started in November 2022 at hospitals attached to Bangalore Medical
College and Research institute (BMCRI). After obtaining ethical committee clearence, an informed written consent was taken from 12 patients
were enrolled into the study. FOT test was performed 24hours before and 24 hours after surgery and results were tabulated using SPSS version 27
and calculated with student t- test. Results:- Out of 12 cases, respiratory reactance at 5 Hz (R5) and respiratory resistance of R5-20 (small airway)
changed signicantly in 4 patients (36%) who underwent surgery for more than 2 hours duration. Respiratory reactance (X5) changed signicantly
in 6 (50%) patients who underwent laparoscopic surgery for more than 2 hours. The study is currently ongoing and the nal results will be displayed
on the day of presentation. Conclusion:- The forced oscillation technique is a clinical tool that can be used to predict respiratory mechanics before
and after surgery. However, it remains to be seen that, it plays a role in predicting clinical outcomes in terns of reducing postoperative morbidity
