Which of the following supplies should be pulled by the surgical technologist for a thoracic procedure?

For a thoracic procedure, a water-sealed drainage system is crucial because it is designed to facilitate safe and effective drainage of air or fluid from the thoracic cavity. This type of system utilizes a water seal to prevent air from re-entering the pleural space, which is key in managing conditions such as pleural effusion, pneumothorax, or general post-operative drainage.

In thoracic surgery, maintaining negative pressure is often essential to enhance lung expansion and promote healing. The water-sealed system allows for the necessary monitoring of drainage while providing a closed environment that minimizes the risk of infection and other complications.

The other drainage systems mentioned are less suitable for thoracic procedures. A passive drainage system relies on gravity and is typically used in other types of surgeries where controlled drainage isn't as critical. The Jackson-Pratt drainage system, while useful for other organs, is not specifically designed for managing the complexities of thoracic drainage. The Andrews-Pynchon suction is specialized for suctioning rather than managing drainage in the thoracic cavity. Thus, the water-sealed drainage system is the most appropriate choice for ensuring optimal surgical outcomes in thoracic procedures.
