and plastic and reconstructive surgery. In subsequent years, several departments and units were established to develop specialisation in the aforementioned areas. Following a shift towards genetic and metabolic diseases, paediatric surgery was introduced as a subspecialty in the Department of Surgery in 1972. In the same year, the Department of Plastic and Reconstructive surgery was officially opened. The department specialised in the treatment of congenital abnormalities, facial and hand injuries and burns. 1972 also saw a major reorganisation of the earlier established Emergency Unit to handle the treatment of both trauma and non-trauma cases. Two years later, the Unit was transformed into the Accident and Emergency Department which subsequently provided 24-hour support for all emergency cases. The Department of Renal Medicine was also established in 1974. Its establishment made dialysis and renal transplant services accessible to the public. In 1975, a Surgical Intensive Care Unit was set up in response to the establishment of several new surgical departments. The Unit, in conjunction with the earlier established Department of Anaesthesia, provided intensive care for patients that underwent surgery. 1980s: Expansion of tertiary medical services The prolific growth of specialised medical treatment in the 1970s fuelled the need for an expansion of existing medical infrastructure. Consequently, the construction of a new SGH complex was commenced in the late 1970s. Built at a cost of S$180 million, the new eight-block complex housing over 1,500 hospital beds and 300 specialists was integrated into the site of its 1926 predecessor and was officially opened by the then Prime Minister Lee Kuan Yew on 12 September 1981. The new hospital complex was designed to serve as a tertiary referral centre for specialised medical services at the national level. In addition, it also facilitated the introduction of several tertiary medical services. Ambulatory services for outpatient care were established to reduce reliance on infrastructure such as hospital beds, thereby cutting costs for both SGH and its patients. The new complex was also equipped with sophisticated laboratory facilities to accommodate clinical research. In 1981, the Department of Cardiology and Cardiovascular Surgery which had been transferred to Tan Tock Seng Hospital was re-established in the new SGH complex. In the same year, paediatric surgery was designated as a separate department. The department introduced its first paediatric bone marrow transplant in 1983. Bolstered by advances in reconstructive microsurgery, the Department of Hand Surgery was instituted in 1985 to provide specialised treatment
