Comparison Of Diaphragm Thickness Values In Cases Of Adenotonsillectomy Before And After The Operation

Introduction: The ultrasonographic assessment in the operating room tends to increase day by day and ultrasonography is a method used to evaluate the thickness of the diaphragm. Measurement of the thickness of the diaphragm is a parameter that can be used to decide before separation from mechanical ventilation and extraction. In these cases where intubated and extubated at the end of the operation, it is planned to examine the ratio of the aperture muscle thickness to each other in the last inspirum and last exprium before extubation. Determining of the present ratio may be meaningful for the determination of the extubation time. Material and Method: In the study, 60 patients, who were in the physical state of ASA I and II, 3-12 age range, and who were scheduled for elective adenotonsillectomy operation were included. Age, gender, body mass index (BMI), and operation time data of patients were recorded. Before and after the operation, inspiratory and exprituar diaphragm thicknesses were measured by ultrasonography. The ratio of the last inspirium and the diaphragm muscle thicknesses in the last expiration were calculated. Results: There was no significant difference between the pre-operation values and the end of the operation in the diaphragm thickness measurements. The incidence of laryngospasm was 1.5 %. Conclusion: Diaphragm thickness measurements with ultrasound have many benefits but further studies are needed. Key words: diaphragm, ultrasound, pediatrik, anesthesia
