Los Angeles ? Love is always the best medicine on “ER.”

After 10 years of the NBC drama, the staff at County General Hospital has created an impressive file of romances. Doctors have played doctor with each other, with nurses and with paramedics.

Forget six degrees of separation — the romantic entanglements of these healers are barely a tongue depressor apart.

Both Drs. John Carter and Luka Kovak, for example, were involved with nurse Abby Lockhart. Dr. Peter Benton had a fling with Dr. Elizabeth Corday, who moved on to Dr. Mark Greene and, lately, Dr. Edward Dorset. All this while curing the sick, making medical breakthroughs and fighting budget battles.

At the start, executive producer John Wells (“The West Wing”) had maintained that the show’s focus was not “young doctors in love.”

“We tried very hard to cast the best actors in those roles,” Wells said in an interview in 1994, the year “ER” debuted. “It was clear we needed extremely talented actors to carry off a combination of compassion and science.”

But even in the midst of extreme trauma, love — or lust — finds a way.

The dedicated healers occasionally find romance outside the emergency room, such as Benton’s relationship with Carla Reese or Carter’s latest love, an AIDS worker he met in Africa. She’s played by Thandie Newton of “Mission: Impossible II” fame.

But it’s mostly all in the family on close-knit “ER.” Here’s a romantic scorecard for many current and former characters based on “ER: The Unofficial Guide” by Mark Jones, “The Complete Directory to Prime Time Network and Cable TV Shows” by Tim Brooks and Earle Marsh, and NBC:
