Millard criteria (Rule of 10) is a set of rules, which is to be fulfilled for undertaking elective surgery for children, and mostly used for reference in

cleft lip A cleft lip contains an opening in the upper lip that may extend into the nose. The opening may be on one side, both sides, or in the middle. A cleft palate occurs when the palate (the roof of the mouth) contains an opening into the nose. The te ...

Hemoglobin Hemoglobin (haemoglobin BrE) (from the Greek word αἷμα, ''haîma'' 'blood' + Latin ''globus'' 'ball, sphere' + ''-in'') (), abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein present in red blood cells (erythrocyte ...

or white blood cells count in every microlitre of blood (WBC < 10,000/uL) Translation to those points: the body weight and age criteria demands a child to have mature cells and tissue before enduring surgical and anaesthetic procedures. At the same point, a child should have had proper body size that enables surgeons to manipulate the tissue without magnification aid. Adequate haemoglobin level will provide good tissue perfusion and oxygen delivery to cells needed for anaesthetic procedure, while leukocyte count will define a child is free from systemic infection that risks jeopardizing the surgery. A child completing all Millard criteria may be taken for elective surgery, such as cleft lip surgery.
