Information was received that a smiths medical snuggle warm pediatric convective warming blanket was used for approximately five and a half hours on an infant during cardiac surgery.Initially, the product was disinfected with chlorhexidine and was set to 40 degrees celsius for the first one and a half hours of use.The patient was positioned above the blanket during the operation, and their buttocks were laid on the portion of the blanket where a shoulder should be applied to.The next two hours, the product was used with the blowing setting (room air reported to be about 22 degrees).Extracorporeal circulation was conducted using an artificial cardiopulmonary apparatus and air was kept ventilated.The patient was monitored by rectal, skin, and pharyngeal temperature measurements.It was noted at an unspecified time that the rectal temperature felt "higher than usual".For the remaining two hours of use, while the patient recovered from anesthesia, the blanket was warmed up to 36 degrees celsius.It was then discovered after the operation that the patient sustained five to six red rashes (sized eight to ten mm) at the sides of the infant's buttocks.The following day, it was reported the rashes developed into blisters.It was also reported the "patient was treated for burn," but detail regarding the medical treatment and outcome is unknown.No additional adverse patient effects were reported.
