Shoulder Arthroscopic Surgery Clinical Trial
Official title:

Study type | Observational |
The investigators applied upper airway ultrasonographic examination focusing the measurement of upper airway diameters in patients undergoing shoulder arthroscopic surgery to evaluate the change of upper airway anatomy before and after the surgery. The investigators also tried to find any findings of ultrasonographic examination that could reliably predict the dyspnea or airway compression after extubation. The investigators tried to compare the ultrasonographic findings with those of chest radiograph to validate the measurements of the ultrasonographic examination. A cuff leak test was preformed to evaluate its ability to predict the upper airway obstruction in shoulder arthroscopic surgery.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Airway transverse diameter | airway transverses diameter measured on the upper airway ultrasonographic image: measure at three level (vocal cord, subglottis, trachea) | 10 min before anesthesia induction | No |
Primary | Airway transverse diameter | airway transverses diameter measured on the upper airway ultrasonographic image: measure at three level (vocal cord, subglottis, trachea) | 20 min after end of surgery | No |
Secondary | depth of skin to airway anterior border | depth of skin to airway anterior border measured at three levels: vocal cord, subglottis, trachea level | 10 min before anesthesia induction and 20 min after the surgery | No |
Secondary | depth of skin to pleura | bilateral depth of skin to pleura at first and third intercostal space on the midclavicualr line measuread on the ultrasonographic image | 10 min before anesthesia induction and 20 min after the end of surgery | No |
Secondary | endotracheal tube balloon cuff pressure | endotracheal tube balloon cuff pressure | 10 min after anesthesia induction and 60 min after surgery start | No |
Secondary | percent cuff leak | The difference in the actual exhaled volume between the averages of pre- and post-cuff deflation was calculated. This number was divided by the tidal volume before cuff deflation and multiplied by 100. The resulting number was recorded as the percent cuff leak. | 10 min after anesthesia induction and 60 min after surgery start | No |
