Caste Question Before Surgery: A Genetic Lifeline?
12 Jul
Summary
- Anaesthetists ask caste in South India to assess genetic risk.
- Rare enzyme deficiency affects drug breakdown during surgery.
- Genetic condition is more common in specific southern Indian communities.
Anaesthetists in southern India are asking patients about their caste before surgery, a practice aimed at identifying a rare genetic condition. This inquiry helps detect pseudocholinesterase deficiency, where the body struggles to break down specific muscle relaxants like succinylcholine. Patients with this inherited condition can face prolonged paralysis and respiratory failure for hours after a procedure.
The genetic deficiency is more prevalent in certain communities in South India, such as the Arya, Vaishya, and some Chettiar groups. Marriages within these communities have contributed to the higher incidence of this inherited trait.
Dr. Sindhu Velayutham explains that this question is not about discrimination but about genetic risk assessment. If a patient or their family has experienced prolonged ventilator support or unexplained paralysis after surgery, it is a crucial detail for anaesthetists to know. Blood tests can confirm the diagnosis, allowing for the use of alternative, safer medications.
