Medical Team

OCL teams travel to Children’s Hospital No.2, Ho Chi minh City, and to Muhumbili Hospital, Dar-es-Salaam to help the local teams to surgically treat up to twenty patients with a complex surgical problem. The local surgeons, anaesthetists and nursing staff all participate in these procedures at every level and are now competent to perform these procedures independently and to an international standard.

Professor Martin T Corbally

Martin Corbally is Chief of Staff and Consultant Paediatric Surgeon at King Hamad University Hospital, Bahrain and Professor of Surgery, RCSI, Medical University of Bahrain. His areas of interest include oncological surgery hepato-biliary surgery, neonatal surgery and upper gastrointestinal surgery.

This has only been possible with the support of many medical and nursing colleagues who have travelled to Vietnam many times over the past 7 years and helped local health care workers to meet international best practice standards. He continues as programme director of a new charitable agency “Operation Childlife” which aims to consolidate further training in Cardiac, Thoracic, Urological, Hand Reconstructive Surgery in Vietnam and also hopes to extend aspects of this training programme to Tanzania and Mongolia.

Professor Mark Redmond

Professor Mark Redmond is a Consultant Cardiothoracic Surgeon in Our Lady’s Children’s Hospital Crumlin and the Mater Misericordiae University Hospital, Dublin. He trained at Johns Hopkins Hospital, USA where he remained on faculty as assistant professor of cardiac surgery and was appointed director of paediatric heart and lung transplantation, director of cardiac research and co-director of the Albert Broccoli Centre for Aortic Diseases. He returned to Ireland in 2000 as a paediatric cardiac surgeon and established the cardiac research laboratories in Beaumont Hospital to study brain injury in cardiac surgery and mechanisms of aortic aneurysm formation in Marfan Syndrome.

He is co-founder and co-owner of UPMC Beacon Hospital in Dublin.

In 2008, through OCL, he initiated the development of a cardiothoracic surgical program in Children’s Hospital Number 2 in Ho Chi Minh City, Vietnam, together with the cardiac team at Our Lady’s Children’s Hospital Crumlin. The goal has been to train the surgeons, anaesthetists and nurses in Children’s Hospital No 2 to perform high quality cardiac surgery in a safe and sustainable program.

Professor Redmond has thus far made four visits to Vietnam to assist in initiating the program and to conduct operational procedures on patients.

Dr. Brendan O’Hare

Brendan was an integral component in the initial development of the programme and thus far has been involved in the care of over 200 children in Vietnam and Tanzania. Having been approached by the Christina Noble Foundation, he approached Professor Martin Corbally with a view to pursuing a joint surgical/anaesthetic trip. Brendan took his first trip to Vietnam in 2004 where he and the team introduced new surgical and anaesthetic techniques for infants – they had not had exposure to invasive haemodynamic monitoring or infant epidurals perioperatively before his visit, anaesthetic techniques that would be deemed essential for safe surgery.

Apart from annual visits to Vietnam since 2004 Brendan has thus far been on two trips to Tanzania where he is providing anaesthetic know-how to doctors there who would not feel themselves to have been adequately trained to undertake the proposed surgery.

Brendan is a consultant paediatric anaesthetist and intensivist at Crumlin Hospital, Dublin and is also a clinical lecturer in the Dept of Paediatrics in Trinity College Dublin medical school.
