AB Note:  Cochrane  review  states  that  venipuncture,  by  a  skilled  operator,  is  the  method  of  choice  for  blood  sampling  in  term  infants.  It  was  found  to  be  less  painful  than  heelstick  sampling  and  a  more  effective  sampling  method.  To  obtain  a  blood  sample  for  routine  analysis  or  blood  culture.  Venipuncture  typically  allows  a  larger  volume  of  blood  (recommended  if  ≥1  mL  needed)  to  be  collected  and  is  the  method  of  choice  for  obtaining  blood  cultures.  It  is  preferred  over  capillary  blood  sampling  for  certain  tests  (drug  levels,  hemoglobin/hematocrit,  karyotype,  coagulation  studies,  cross-matching  blood,  and  ammonia,  lactate,  and  pyruvate).  Arterial  blood  is  preferred  for  lactate,  pyruvate,  and  ammonia.To  obtain  a  central  hematocrit.  Venipuncture  is  more  reliable  than  heelstick.Administer  medications.Venous  blood  gas.  This  can  be  used  in  some  diseases  (neonatal  sepsis/respiratory  distress  syndrome  [RDS])  to  diagnose  acid-base  imbalance  if  an  arterial  blood  gas  can't  be  obtained.  Although  arterial  blood  gas  is  preferred,  venous  samples  show  good  validity  in  terms  of  pH,  Pco2,  and  HCO3.
