Anesthesia medicine may affect brain development in a child under 3, or an unborn baby whose mother receives this medicine during late pregnancy. These effects may be more likely when the anesthesia is used for 3 hours or longer, or used for repeated procedures. Effects on brain development could cause learning or behavior problems later in life.
Negative brain effects from anesthesia have been seen in animal studies. However, studies in human children receiving single short uses of anesthesia have not shown a likely effect on behavior or learning. More research is needed.
In some cases, your doctor may decide to postpone a surgery or procedure based on these risks. Treatment may not be delayed in the case of life-threatening conditions, medical emergencies, or surgery needed to correct certain birth defects.
Ask your doctor for information about all medicines that will be used during your surgery or procedure. Also ask how long the procedure will last.
It is not known whether methohexital passes into breast milk or if it could affect the nursing baby. Tell your doctor if you are breast-feeding.
