About
The purpose of this study is to determine if a shorter-acting spinal anesthetic called mepivacaine has advantages over a longer-acting medication called bupivacaine.
Full description
Different medications last for different amounts of time and can be changed depending on the length of the procedure. A short acting spinal is generally used for procedures lasting less than 90 minutes. A longer acting medication would be any that lasts longer than 90 minutes. These medications not only block the signals that travel along the pain nerves, they also prevent the signals that tell the patients muscles to move. This means that after a total knee replacement a patient may delayed in their ability to get up and start walking early after surgery. Walking early in the recovery has been shown to decrease the rate of pulmonary embolism and death. Ambulating early is also important to prevent loss of strength, constipation, pneumonia and urinary retention.
