KMCRI pioneers new scientific method to treat snakebite victims
Traditionally, snakebite patients admitted to hospitals were given ASV injections immediately. However, the new method introduced at KMCRI's Multidisciplinary Research Unit (MRU) involves first collecting a blood sample from the victim and analysing it for specific enzymes present in snake venom. Based on these findings, doctors decide the exact dosage of ASV — or whether it is needed at all.
Speaking to The Hans India , Dr. Ram Kaulugudda, the nodal officer of the MRU, explained that until now, hospitals would administer ASV indiscriminately. 'ASV is expensive and unnecessary doses create both financial and health burdens. Our study has proven that identifying the venom levels through blood tests allows us to treat only those who genuinely need ASV,' he said.
Under the new protocol, patients who come to KMCRI after a snakebite undergo a quick blood test. Doctors check for symptoms such as swelling, breathing difficulties, blood pressure fluctuations, nervous system impact and blood clotting disorders. The venom enzymes are measured using advanced ELISA machines. If venom levels are high, the patient receives the required ASV dosage. If the venom level is minimal, supportive treatment without ASV is administered. 'This is the first research of its kind in India,' Dr. Kaulugudda said proudly. 'It offers a clear guideline on who needs ASV and who does not. This will help rural hospitals too, where the misuse of ASV is common due to lack of testing facilities.'
KMCRI researchers revealed that 82 snakebite victims were tested as part of this study. Blood was collected immediately, then again at 24 and 72 hours to monitor changes in venom enzyme levels. Doctors then adjusted treatment accordingly. 'The severity of venom decides survival chances. Knowing the enzyme level early gives us a head start on treatment and prevents premature discharge when venom might still be present,' Dr. Kaulugudda added. The study found significant differences in venom levels between species. For example, bites by cobras, vipers, kraits and Russell's vipers showed varied venom enzyme patterns in the blood. Depending on the species and severity, patients either received ASV or continued on supportive therapy.
'In the past, many patients insisted they were fine and asked to be discharged, unaware of hidden venom levels. This study gives us a scientific basis to decide whether a patient is genuinely ready to go home or needs further observation,' Dr. Kaulugudda said. The research began with a pilot project in 2020, studying 20 snakebite patients in Dharwad district — 16 men and four women aged between 18 and 65, mostly farmers. Of these, 12 had bites below the knee. Depending on venom levels, some were given ASV within three hours, while others received it between three to eight hours after admission.
KMCRI now plans to share its findings with the state government. The team believes that deploying similar testing units in rural hospitals will help identify venom severity and decide whether to treat locally or refer the patient to a higher centre for advanced care. 'This research is not just about saving lives — it's about rationalising the use of life-saving drugs, saving money and ensuring patients get the right treatment at the right time,' Dr. Kaulugudda concluded. If scaled up, KMCRI's innovative protocol could become a national model, offering India's rural snakebite victims a better chance at survival while using resources wisely.

World Brain Health Day: Stroke management and head injury care to be provided on a ‘hub-and- spoke' model in Karnataka
Soon timely stroke management and head injury care will be available for people in government medical colleges closer to their residing districts. NIMHANS in coordination with the State government has developed 'hub-and-spoke' model for stroke and head injury care across Karnataka. Under this model, an advanced stroke and head injury centre (hub) at NIMHANS will coordinate for establishment of spoke centres in six medical colleges and provide guidance and support across the State. July 22 is observed as World Brain Day and the theme for 2025 is 'Brain Health for All Ages.' A stroke occurs when the blood supply to part of the brain is disrupted, either by a blockage or a bleed, causing brain cells to die due to lack of oxygen and nutrients. This can lead to a range of disabilities, from mild weakness to severe paralysis, and in some cases, permanent disability and even death. Golden hour Recognising the symptoms and seeking immediate medical attention within the 'golden hour' - four to six hours after symptoms begin - is crucial for minimising damage and maximising recovery. Immediate treatment can significantly improve outcomes by restoring blood flow to the brain and preventing further cell death, doctors said. The stroke management and head injury care project will be on the lines of Karnataka's heart attack (ST-Elevation Myocardial Infarction - STEMI) management project currently running in 86 taluks. The hub-and-spoke model will avoid delay in providing stroke diagnosis and treatment apart from head injury care to needy patients. Accessibility to timely care closer to their place of stay will avoid patients rushing to NIMHANS, thereby ensuring there is no congestion at the premier mental health institution. At NIMHANS six to 12 stroke patients and 15 to 16 head injury cases are seen daily. NIMHANS apex centre Girish B. Kulkarni, Professor of Neurology and head of the stroke unit at NIMHANS, told The Hindu on Monday that the hub-and-spoke model for stroke management, involves a network of healthcare facilities where NIMHANS - the apex stroke centre (hub) will provide advanced care and support to surrounding smaller facilities (spokes). 'This model aims to improve stroke outcomes by streamlining access to timely and appropriate care, especially in the crucial 'golden hour' after a stroke,' Dr. Girish said. While the apex centre at NIMHANS started three months ago, a spoke centre at the Karnataka Medical College and Research Institute (KMCRI) in Hubballi has started tracing stroke patients and has been providing routine stroke management recently. With funding from the State government, KMCRI is all set to get a Digital Subtraction Angiography (DSA) machine shortly. This equipment is used in stroke management to visualise blood vessels in the brain and identify blockages or abnormalities that may be causing a stroke, the doctor said. Apart from KMCRI, spoke centres will be established in government medical colleges in Bengaluru (Bangalore Medical College and Research Institute), Mysuru Medical, Raichur and Ballari. 'We have identified the colleges and the centres will be established soon at a total cost of ₹56 crore,' Dr. Girish said. Brain health Karnataka's Brain Health Initiative (KaBHI) being run in collaboration with NIMHANS has helped improve early detection and management of neurological disorders at the grassroots level. The initiative has trained primary healthcare providers — including doctors and nurses — to identify and treat common neurological conditions such as stroke, epilepsy, and headache in district and taluk hospitals. This has already brought neurological care closer to the people, especially in rural and semi-urban areas, and reduced delays in diagnosis and treatment.

Orissa HC seeks govt reply on delay in expanding NAT-PCR blood testing across state
CUTTACK: The Orissa High Court has sought a detailed response from the state government after a contempt petition was filed by advocate Prabir Kumar Das over its alleged failure to implement nucleic acid testing polymerase chain reaction (NAT-PCR) blood testing facilities in all blood banks as promised. The division bench comprising Chief Justice Harish Tandon and Justice MS Raman on Thursday directed the commissioner-cum-secretary of the Health and Family Welfare department to file an affidavit within two weeks, outlining the steps taken to fulfil the commitment made in court in November 2023. The matter has been posted for further hearing on August 4. The directive comes in response to a contempt petition filed by Das on April 2, 2025. In his plea, Das contended that the state government had wilfully violated the high court's order dated November 30, 2023, which required the establishment of advanced NAT-PCR testing facilities in all 56 blood collection centres of the state by the end of March 2025. The court order had followed Das' earlier PIL that highlighted the risks associated with blood transfusions using traditional ELISA-based screening. He had argued that the NAT-PCR technology allows for early detection of infections such as HIV 1 and 2, Hepatitis B, and Hepatitis C, thus ensuring safer transfusions. In its affidavit filed in response to the PIL in November 2023, the Health department had stated that 47 per cent of the blood collected in Odisha was being tested using NAT-PCR technology at 11 centres. The government had assured the court that it would expand the facility to all 56 blood centres at an estimated cost of `200 crore by March 2025. However, Das, appearing in person, submitted that information obtained through RTI queries from the directorate of Blood Safety (March 3, 2025) and the Health department (March 17, 2025) confirmed that only the original 11 centres were equipped with NAT-PCR, and no progress had been made in the remaining 45 centres. Calling the inaction a 'deliberate and wilful violation' of the court's order, Das urged the bench to initiate proceedings under the Contempt of Courts Act against the commissioner-cum-secretary. The court, while not initiating contempt proceedings, has directed the official to respond with a status update in two weeks.

File affidavit detailing NAT-PCR rollout in blood collection centres: HC to govt
1 2 Cuttack: Orissa High Court on Thursday directed the state's health and family welfare department to file an affidavit within two weeks detailing the steps taken to implement Nucleic Acid Testing Polymerase Chain Reaction (NAT-PCR) blood testing facilities in all govt-run blood collection centres. The directive came after a petition was filed by advocate Prabir Kumar Das. A division bench comprising Chief Justice Harish Tandon and Justice M S Raman passed the order while hearing the petition, which sought contempt proceedings against the commissioner-cum-secretary of the health and family welfare department for allegedly failing to comply with the court's earlier directive issued on Nov 30, 2023. The court had, at the time, disposed a PIL filed by Das calling for the introduction of advanced NAT-PCR testing in all blood banks, citing that the method allows for earlier detection of HIV 1 & 2, and Hepatitis B and C, compared to the traditional ELISA test. In its 2023 affidavit, the state govt had informed the court that 47% of the state's blood collections were already being tested via NAT-PCR at 11 centres and that it had decided, in principle, to extend the facility to the remaining 45 centres by March 2025 at a cost of Rs 200 crore. However, in his contempt plea filed on April 2 this year, Das submitted that information obtained via RTI from the directorate of blood Safety (on March 3) and the health department (on March 17) revealed that no progress had been made, and NAT-PCR testing remained limited to the same 11 centres. "The govt made a commitment before this court and failed to act on it. This amounts to a deliberate and wilful violation of the court's order," Das said before the bench, appearing in person. Taking note of the submissions, the bench asked the commissioner-cum-secretary to clarify what actions had been initiated since the court's directive and fixed the next hearing for Aug 4. In his original PIL, Das had highlighted the risks of transfusing infected blood due to the limitations of ELISA testing. He urged the court to ensure the implementation of NAT-PCR testing across all centres in a time-bound manner to ensure safer blood transfusion practices.
