Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

During shoulder arthroscopic surgery, extravasation of irrigation fluid can occur around the shoulder and trachea, compressing the upper airway. Although the extravasation is generally reabsorbed asymptomatically within 12 hours, there are cases that lead to reintubation or life-threatening complications. Furthermore, the soft tissue edema around the shoulder may extend to the thoracic cage, compress the chest and induce the respiratory distress immediately after surgery. The investigators attempt to determine the effect of shoulder arthroscopic surgery on respiratory mechanics. Changes in respiratory mechanics and arterial blood gases were measured and compared before and after the shoulder arthroscopic surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Currently, most shoulder surgeries are performed with arthroscopy. The advantages of shoulder arthroscopic surgery are decreased blood loss due to minimal incision for scope, a reduced operation time, minimization of surgical stress, and rapid recovery time after surgery. During shoulder arthroscopic surgery, extravasation of irrigation fluid can occur around the shoulder and trachea, compressing the upper airway. Although the extravasation is generally reabsorbed asymptomatically within 12 hours, there are cases that lead to reintubation or life-threatening complications. Furthermore, the soft tissue edema around the shoulder may extend to the thoracic cage, compress the chest and induce the respiratory distress immediately after surgery. From these facts, the mechanism of respiratory discomfort after shoulder arthroscopic surgery may be because the upper airway obstruction or restrictive pathology due to direct compression of thoracic cage by the soft tissue edema. There have been no studies on the respiratory effect of shoulder arthroscopic surgery. We have observed frequent and severe respiratory discomfort after the shoulder arthroscopic surgery. Therefore, in this study we attempt to determine the effect of shoulder arthroscopic surgery on respiratory mechanics. Changes in respiratory mechanics and arterial blood gases were measured and compared before and after the shoulder arthroscopic surgery.
