Here is an edited transcript of the interview:

WOLF BLITZER, CNN ANCHOR: In Haiti today, this could be a day that would determine whether thousands of people live or many more die. Water, food and medicine are arriving, but getting it to the people is a problem, with the clogged airport, the damaged port, and the devastated roads.

Joining us now on the phone is Dr. David Gettle. He's a medical doctor with Samaritan's Purse, which is an international Christian relief agency. He was in Haiti within 24 hours after the earthquake. And he's among the medical professionals who need supplies, bringing supplies, trying to do a job. What's it like, Dr. Gettle, based on your experience over these past several hours?

DR. DAVID GETTLE, MEDICAL RESPONSE LEADER, SAMARITAN'S PURSE: Well, what we're seeing is, as you said, there's just a need of supplies, everything from as simple as Betadine up to more specific as far as orthopedic surgery instruments and pins.

Currently, we're at a hospital operating out of the Baptist Haiti Mission. It's a 100-bed hospital. And, this morning, the count was 300 patients. We don't talk in terms of bed counts here. We talked in term of bed and floor counts.

We have opened up other rooms outside of the hospital. And we're triaging patients to those areas that can last until we get more aid in here.

BLITZER: What is your most immediate requirement?

GETTLE: Right now, the most immediate requirement appears to be -- ours is physicians, which we have initiated and have brought in six already. So, that one hospital is staffed.

But simple things -- again, like I just said, we're running out of Betadine, and they have open wounds. I have people laying on the floors and beds that have obvious deformed fractures just looking at them, and they have been laying there now for two days.

Sutures, just everything that we think of rudimentary, they do not have it. We started tearing up some bed sheets to use for bandages or to hold the bandages on.
Water is an issue, as far as the water you can drink and the water that you can use to clean patients with. We have just brought in two water-filtration units. Each one will give us 10,000 gallons per day of usable, drinkable water. And those are headed up to that one hospital now.

As you can tell, the needs are great. And even though we're able to help this one hospital, there are many, many more. We have reports of a pediatric hospital in Petionville collapsing, and parents and concerned loved ones standing around waiting to find out if there -- if the patients in that hospital have been recovered or can be removed at this time.

BLITZER: Well, Dr. Gettle, good luck to you. We're counting on you. We're counting on so many others to save lives. This is a critical day right now, 72 hours or so after the earthquake. There are still people, perhaps thousands of people, still alive who are in the rubble of those crushed buildings, but they're working desperately to save them. And they're working desperately to save lives.
