Edward's syndrome (trisomy 18) is the second most common chromosomal anomaly next to Down syndrome. The patients are dysmorphic, have multiple organ malformation which is made to die with 90% by 12 months. Information in the literature about anesthetic management in trisomy 18 is rare. We report the case of a 7 months old male with trisomy 18 who underwent inguinal hernioplaty and orchiopexy with general anesthesia.
