Sachithanandan Thambinathan, known as T. Sachithanandan, was a Malaysian anaesthesiologist (1931–1981). He was born in Kuala Lumpur to Indian-Malayalam parents with Sri Lankan Tamil roots. He studied at Victoria Institution and earned his MBBS in 1957 from the University of Calcutta, where he was the founding president of the International Students Association.

He trained in anaesthesia in the United Kingdom from 1961 to 1964, working with noted British anaesthesiologists. He received the Fellowship in Anaesthesia from the Royal College of Surgeons in Ireland in 1963 and the Diploma of Anaesthesia from the Royal College of Surgeons, England.

In 1964, he and John Francis Nunn and colleagues were among the first to show that airway closure at residual lung volume can cause desaturation due to unventilated areas of the lung. This finding has influenced how doctors manage mechanical ventilation in the critically ill.

Sachithanandan returned to Malaysia to work at Johor Bahru General Hospital (now Hospital Sultanah Aminah). He served there in two periods, 1964–1971 and 1977–1981. He helped establish the first public sector intensive care unit in Malaysia in 1968 at JBGH, which inspired the creation of other ICUs nationwide. In 1969, he helped set up Malaysia’s first postgraduate medical centre at JBGH with colleagues Lim Kee Jin and Samuel C.E. Abraham.

In 1972, he was elected President of the Malaysian Medical Association, the first anaesthetist to hold that post. He was Chief of Anaesthesiology at Ipoh General Hospital from 1972 to 1977 and helped establish the state’s first postgraduate medical centre there in 1976. He also played a major role in shaping local specialist training and the criteria for a local Masters in anaesthesia, contributing to a program that trained many doctors by 2008.

Sachithanandan pioneered regional anaesthesia nerve blocks in Malaysia. He helped found the Malaysian Society of Anaesthesiologists in 1963 and later served as its president (1968–1969). He was an early member of the Academy of Medicine, Malaysia (1969). He helped design Johor Specialist Hospital, the state’s first private hospital and a landmark for KPJ hospitals, though he did not practice there before his death.

He passed away on 28 May 1981, at age 49, after a coronary bypass operation in London. His legacy includes advancing anaesthesia and intensive care in Malaysia, training many specialists, and elevating the status of anaesthesiologists.

In 2018, the Malaysian Society of Intensive Care launched the T. Sachithanandan Best Oral Presentation Award in his honor. He also contributed to sports and community work, including cricket administration and several charitable organizations. He married Punithavathy Sinnathuray in 1965, and they had two children, both trained as doctors in Dublin.
