(NECN: Katie Davis) - Doctors, nurses and other volunteers returned to the Worcester area after treating patients about 40 miles outside Port-au-Prince. The team from Forward in Health returned to Massachusetts Sunday, tired but satisfied after six days of treating patients in Haiti. They spent the past week treating earthquake victims in conditions one doctor compared to the Civil War. The team is exhausted, but knows the hard work made a difference. "I think everyone is very overwhelmed by what we saw, but we feel very satisfied that we were able to help out," pediatrician Dr. John Mulqueen said. Dr. Mulqueen and the rest of the team from Forward in Health saw patients who received no medical attention since the quake struck more than a week ago. Many were suffering with serious injuries, including a 12-year-old boy whose leg needed to be amputated. "We did the best we could, but it came down to saving his life, and we ended up having to do an amputation," Dr. Mulqueen said. Forward in Health has been sending medical teams to Haiti for several years, experience that helped them respond to this disaster. Still, team members were shaken by what they saw. "It's kind of hard to explain. For someone who hasn't been there, there are no words," nurse Marjorie Pickering said. "I was anticipating the worst, and we really saw the worst." Pickering grew up in Haiti and still has family there. Her relatives are safe. But she saw many others suffering with untreated broken bones and open wounds, and was touched by their positive attitude. "We had little boys and little girls that were walking around with a broken arm," Pickering said. "It was amazing for me to see." With the country's infrastructure devastated by the earthquake, getting help to those who need it is challenging. "Moving around the country is very difficult. Some of the road are getting to be impassable with each tremor," volunteer John Altomare said. "The roads are deteriorating." The focus now is on organizing future trips, as Haiti begins the long recovery that lies ahead. More volunteers from Forward in Health plan to return to Haiti next week. They hope to check on some of the patients they treated during their most recent trip.
