Lamar Odom Status: 'Dire Straits'

Lamar Odom has not gotten any better, and sources familiar with his treatment say even if he survives he has virtually no chance of ever leading a normal life.

Our sources say doctors continue to put Lamar's chances of survival at 50/50. We're told he showed "absolutely no improvement" Thursday from the condition he was in when he was admitted to the hospital Tuesday. As one person put it, "He's in dire straits."

One of the big issues is Lamar's apparent consumption of cocaine and an herbal substitute for Viagra, which is a potentially deadly combination.

We're told he was "entirely unresponsive" all day Thursday and 4 vital organs are still failing, with no signs of improvement. Lamar is not breathing on his own and his doctors believe his brain function is significantly reduced.

We're told the Kardashian family has flown in several specialists from L.A. to consult with Vegas doctors.

One source said there are comparisons to the plight of Bobbi Kristina, with one big difference. We're told Lamar did not lose oxygen to the brain for nearly as long as Bobbi Kristina, which offers some sliver of hope.

Doctors have told the family for each day that passes without improvement, the prognosis gets bleaker.
