Struan Keith Sutherland AO (17 June 1936 – 11 January 2002) was an Australian medical researcher who developed effective antivenoms and other treatments for people bitten or stung by venomous Australian wildlife.

Sutherland was born in Sydney and grew up in Bendigo, Victoria. He studied medicine at the University of Melbourne, graduating in 1960, and served in the Royal Australian Navy from 1962 to 1965.^[1]

In 1966, Sutherland joined the Commonwealth Serum Laboratories and was soon appointed Head of Immunology Research, a position which he held for 28 years. The death in January 1979 of a young girl, Christine Sturges, from a funnel-web spider bite prompted Sutherland to look for a funnel-web spider antivenom.^[2] Many previous researchers had failed to develop such an antivenom, but Sutherland persevered.

In January 1980, a two-year-old boy James Cully was bitten by a funnel-web spider, and died three days later. This was the spider's 13th recorded victim. Later that year, Sutherland's team produced an effective antivenom;^[1] since then, no deaths have been recorded from funnelweb spider bites.^[3] The antivenom had its first success when it was used to treat a 49-year-old Sydney man, Gordon Wheatley, who was bitten by a funnel-web spider on 31 January 1981. He completely recovered after 2 days in hospital.

Sutherland also led research into snakebite treatment, working on antivenoms and developing venom detection kits to help hospital staff determine appropriate treatment for a bite.^[4]

In the 1970s, he developed the pressure immobilisation technique (a first-aid procedure) for both snake and funnelweb bites,^[5][6] replacing treatments such as tourniquets that were often harmful to the patient.^[7]

In 1994, CSL was privatised and the antivenom research program was closed, prompting Sutherland to leave the organisation for the University of Melbourne. Here he founded the Australian Venom Research Unit, where he worked until 1999 when striatonigral degeneration, a condition similar to Parkinson's disease, forced him to retire. Even in retirement he continued to work, co-authoring three books,^[2] including "Venomous Creatures of Australia", which became its publisher's (Oxford University Press) best-selling Australian book.

Sutherland was married three times.

In the Australia Day honours of 2002, two weeks after his death, Sutherland was appointed an Officer of the Order of Australia (AO), effective from 7 February 2000, for "service to science as a leading contributor to research in clinical toxicology and the biology of Australia's venomous creatures, and for the development of the funnel web spider antivenom".^[9]
