Baby died after tongue operation Southend Hospital operation
A 17-day-old baby died of an infection after a tongue-tie operation, an inquest has heard.
Nicholas Baldwin, a twin who lived in Leigh on Sea in Essex, died at Southend University Hospital in November 2010.
An inquest at Southend Magistrates' Court heard how the baby contracted klebsiella oxytoca sepsis, an infection, from an unknown source.
Acting Coroner for Southend and South East Essex Yvonne Blake recorded a verdict of death by natural causes.
Ms Blake said all protocols had been followed by the hospital.
"We will never know where Nicholas got the infection from," she said.
Tongue tie results from the frenulum, which is the membrane under the tongue, extending further than usual towards the tip of the tongue.
It limits the forward and upward mobility of the tongue.
