The man was later transferred to the Freeman Hospital in Newcastle for further surgery and is in a critical condition.
Eight men aged between 23 and 59 have been arrested and remain in custody.
Anyone with information is urged to contact Cumbria Police on 101.
"The incident happened during a party to celebrate the New Year.
