No. First rule to remember: Never give up on or dump a beer!
Just clean up the mess, spray sanitizer around and resanitize your airlock -- or put in a blow-off setup. Keep in mind some large commercial breweries use open fermenters with no lid. There is a protective layer of CO2 covering the top of your brew.
Blowoff tubes (into pitchers of water). A blowoff tube is really just a giant airlock, big enough to pass gobs of krausen. Only the center has an airlock, others have tubing stuck into the airlock hole in the bung.
