Therapies like meditation, relaxation, aromatherapy, reflexology and Indian head massage will be offered on site at the hospital.
The service has been made possible through the generosity of the Julie Wren Trust and the Children’s Medical Research Foundation at the hospital.
The Trust was established in memory of Julie Wren who died of cancer at the age of eight.
Julie’s mother Esther Wren said the new therapy room was “a dream and today the dream has become a reality”.
The aim of the unit is to help ease some of the stress, anxiety, pain, nausea and suffering for both children and their parents at the National Children’s Haematology and Oncology Centre.
A skilled Complementary therapist , who is also a children’s nurse and who has years of experience in treating children with cancer will provide the new service.
The Julie Wren Trust has also provided funding for a half time complementary therapist for a timeframe of five years.
The room was officially opened by RTE’s Miriam O’Callaghan
Speaking at the opening, Assistant Director of Nursing, Dympna Cawley said: “this service will mean a great deal to our patients.
“The therapy room is an oasis of calm and will be extremely well used.
“Complementary Therapies are best described as therapies that can be used with conventional medicine.
“They are used to promote well being and to manage symptoms related to cancer treatment.
“It is important to note that our Complementary Therapy Service is used in conjunction with our conventional forms of treatment which treat and cure cancer.
The service, she added, gave parents and children the opportunity to “focus on their spiritual & emotional wellbeing.
“It empowers parents and children and they feel more in control of their illness.”
