Abstract
A method of securing a patient onto an operating table when the patient is in a position such as the trendelenburg position and apparatus therefor including a kit. A viscoelastic pad is used to support and hold a patient on a medical procedure table during a medical procedure performed while the table, and thus the patient lying thereon, is in an inclined position, such as the Trendelenburg position. The viscoelastic pad has characteristics which promote a minimization of pressure forces on the patient's body, as well as promote a secure cushioning and holding of the patient in a desired position on the table, in order to minimize injury to the patient.
