Comparison of effects of lma on ventilation functions after induction with vima and tiva in arthroscopic surgery

Purpose: In this study, our purpose was to compare the effects of LMA appliance after VIMA or TIVA induction on respiratory functions in arthroscopic procedures.Material-method: The study was performed in operating room and polyclinic on pulmonary diseases in Medical Faculty Hospital of the University of Duzce. Fifty patients, who were undergoing arthroscopic surgery under general anesthesia between age 18-60 and classified as ASA 1-2 were included after their informed consent was taken. In the operating room electrocardiography (ECG), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), heart rate (HR), peripheric oxygen saturation (SPO2) were monitorised.Respiratory function test was performed to all patients included, preoperatively, on 2nd hour postoperatively and on 24th hour postoperatively in the sitting position, after defining how the test works. The test was performed 3 times each and the highest FVC and FEV1 values were selected.Results: FEV1, FVC, FEF%25-75 values postoperatively were significant lower than the values preoperatively and by discharge, but between FEV1, FVC, FEF%25-75 values preoperatively and by discharge were no significant difference. Additionally, FEV1 and FVC values in group VIMA were significantly lower than in group TIVA on every 3 test periods.FEV1/FVC values were not significantly different between two anesthesia groups. In addition to that, there was no significantly difference between test periods preoperatively, postoperatively and by discharge.Conclusion: In conclusion, we determined by each two anesthesia groups that respiratory parameters like FVC, FEV1, FEF %25-75 were decreased. By each two anesthesia groups were lung functions decreased and FEV1/FVC values were remained. More studies on lung functions by different anesthesia technics are needed.KEYWORDS; respiratory functions test, laryngeal mask airway, VIMA, TIVA, arthroscopy.
