Sai Baba's condition still very critical: Doctors

"The response shown to the treatment continues to be minimal by all the vital organs and his heart rate and blood pressure continue to be low and supported by drugs," A N Safaya, director, Sri Sathya Sai Institute of Higher Medical Sciences said in a medical bulletin in Puttaparthi.

There is no significant change in his overall clinical condition since Thursday. The doctors, however, are continuing round-the-clock treatment of 86-year-old Sai Baba, Safaya said.

Sai Baba was hospitalised on March 28 following problems related to heart and respiration.

As a precautionary measure, the state government has deployed additional police forces in Anantapur district particularly Puttaparthi town to maintain law and order.
