On behalf of the Neurotrauma committee of the Asian Australasian Neurotrauma Society I welcome you to Phnom Penh Conference on Essential and Emergency Surgery and Anesthesia. The primary goal of the AASNS education committee is assist in reducing the toll of neurotrauma in developing countries through prevention, improved treatment, education and research. In this conference a panel of international and national experts will consider how the best quality surgery and anaesthesia can be made available to all in need. This will provide an excellent framework on which to consider the ways in which neurotrauma care can be improved from the point of injury onwards.

The delegates will have the opportunity to form valuable relationships through scientific and social interchange, to enjoy Cambodian hospitality and to see something of this fascinating and beautiful country.

2015 has seen surgical care rise from its “neglected” status to take its proper place within global health priorities. The transition would not have been possible without the new evidence describing the magnitude of unmet need of surgical services in low income countries presented by The Lancet Commission on Global Surgery early 2015. Along with several other key factors, the momentum to recognize surgery as an “indivisible and indispensable” part of health care resulted in passage of the World Health Assembly resolution 68.15 calling for “Strengthening emergency and essential surgical care and anaesthesia as a component of universal health coverage”.

During the first day of this conference, various stakeholders in surgical capacity building in South and Southeast Asia will have an opportunity to hear presentations from The Lancet Commission, World Health Organization and others about burden of unmet surgical need and what the UN member states have agreed to do about it.

The second day will be devoted primarily to discussing how best to address neurosurgical issues as it pertains to essential and emergency surgical care at the district hospital level.

We look forward to two exciting days of stimulating and passionate discussions for a cause we all believe in; health care, including surgical care, should be accessible to all, wherever, whenever it is needed.

Warm regards,

The Organizing Committee.
