Doctors in Kathmandu had been working round-the-clock on Monday 7 April to treat patients suffering from injuries sustained in the earthquake.

Nepals government-owned Bir Hospital has been accepting most of the trauma injuries after a magnitude 7.9 earthquake hit Kathmandu City on 25 April.

The hospital has seen 105 dead so far, of which nine died before arrival, hospital officials said. Most of the deaths have been as a result of multiple organ injuries.

There are a lot of patients who have got a devastating injury, including head as well as the amputation of the limbs, whole limb amputations. A lot of devastating injuries including chest, badly chest injuries, said Dr Ganesh Gurung, vice chancellor of National Academy of Medical Science.

Twenty-five year old Sudarshan Lamichhane, a resident of Kathmandu, was looking after his brother who had been trapped under a collapsed building.

Actually what happened was he was under the building for three hours and he was rescued by our rescue team and was taken to the hospital. But now he has some swelling problems, he said.

Lamichhane added that the governments help has been satisfactory considering they actually opened the trauma centre to take care of critically injured people including his brother.

Overwhelmed authorities were trying to cope on Monday with a shortage of drinking water and food, as well as the threat of disease.

The sick and wounded were often lying out in the open in Kathmandu, unable to find beds in the devastated citys hospitals. Surgeons set up an operating theatre inside a tent in the grounds of Kathmandu Medical College.

Nepals police said in a statement that 3,617 people have died in Saturdays 7.8 magnitude earthquake, including 1,302 in the valley of capital Kathmandu alone. That does not include the 18 people killed in an avalanche, another 61 people killed in neighbouring India and 20 in Tibet.

It is the worst earthquake in Nepal since 1934 when 8,500 died. More than 6,500 have been injured.
