The BRD Medical College specified that 34 were babies who died at the neo-natal intensive care unit, while 12 died because of encephalitis. The rest died of other unspecified causes, AAP reported.
Local media reports have said some of the deaths were caused due to an oxygen shortage after a private supplier withdrew its equipment over unpaid hospital dues.
BRD Medical Chief Medical Superintendent Dr R.S. Shukla has denied the claim.
The hospital, in a statement, said there had been a "drop in pressure in the supply of liquid oxygen" on Thursday, but added cylinders were procured from various other suppliers.
It did not specify whether that had resulted in any deaths.
The breakdown of the death toll provided by the hospital showed a spike on Thursday, with 23 fatalities, including 14 babies at its neo-natal unit.
The Uttar Pradesh and federal governments are investigating the matter, officials said.
