The hydrocarbon feed - one of the main sources of pollution. A new study by University School of Medicine in New York and published in the Journal of Cataract and Refractive Surgery, found that the medical center in India is a model for rational use of resources. In carrying out cataract surgery clinic Aravind (Aravind) in south India 96 percent less carbon than in the UK. Cataract is the leading cause of blindness and visual impairment worldwide.
"Excessive use of disposable materials in surgery not harmless - says Cassandra Thiele, head of research, associate professor of public health School of Medicine, New York University -. Ophthalmology and other medical professionals to look for ways to reduce the use of materials and emissions during medical procedures. The center in India can serve as a model. "
From November 2014 to February 2015 researchers analyzed surgical materials, energy and waste during cataract surgery and the calculated greenhouse gas emissions and emissions associated with ozone depletion, and toxic air pollutants. The authors found that Aravind only four per cent of emissions in comparison with similar operations in the UK. In particular, emissions were 6 kilograms of carbon dioxide compared to an equivalent of 160 kg in the UK.
Clinic model was to reduce the duration of the operation, re-use of surgical gowns, caps and blankets, multiuse pharmaceutical preparations and more efficient sterilization of instruments, stainless steel, so they can be reused in the same day.
India aims to double the current rate of operation and save them from blindness even more people, that is the aim of the World Health Organization initiative "Vision 2020".
If Indian ophthalmologists using modern surgical techniques to the UK to achieve their goals, they would be giving the greenhouse gases that are comparable with the annual mileage 250,000 passenger cars. If the clinic used the approach Aravind, the greenhouse effect would be comparable to the mileage only 9,000 passenger cars.
"To the extent that health systems and professionals in the world are more concerned about the consequences of climate change and the overuse of resources for public health, it should be understood, and to promote effective models of care," - says Dr. Thiel.
"Aravind model for surgery (use of reusable instruments, energy-saving appliances and air conditioning systems) is an example of a more sustainable and efficient cataract surgery , "- adds senior author Joel S. Schuman, MD, Head of the Department of Ophthalmology School of Medicine, New York University.
