The purpose of this study is to look at whether the use of a simple technique before surgery, which involves inflating a blood pressure cuff on the infant's leg, can improve development of language, motor and thinking skills at 12 months of age. Some research has found that a brief shortage of blood supply to an organ (such as a leg) at level that does not cause harm may help the body to tolerate a longer and more severe shortage of blood (for example, during surgery).
