Trauma is a television series which originally ran on NBC from September 28, 2009 to April 28, 2010 and focused on a group of paramedics in San Francisco, California.
A month after its premiere NBC announced it would not order any further episodes, but would broadcast the 13 episodes ordered. On November 19, 2009, NBC reversed its decision, announcing it had ordered three additional episodes of the series, bringing the order to 16 episodes; the order was extended to 20 episodes on January 20, 2010, as part of a package of episode orders that followed the demise of The Jay Leno Show. Trauma returned on March 8, 2010, with the season finale scheduled for May 10, 2010. In early April 2010, NBC reduced the episode order down to 18 and announced an April 26, 2010 finale. On May 14, 2010, the show was cancelled by NBC.
