As the child was extremely restless trying to give any I.V injection was utter failure. so child was wrapped in a blanket one alone was exposedIcaught hold of the hanug efectsd &showed the vein to the nurse another nurse brought  inj.digoxin+lasix with 10 ml dilution in 24 size butter fly needle.The injection was given successfully,&blanket removed.No sedation was given as the previous doctors would have given more than enough sedation
