The neonatal intensive care unit [NICU] is full of buzzers, bells and the steady hum of technology. The machines that line the rooms are safeguarding the most fragile human lives. How reassuring ... is the sound of a friendly voice? The look of a friendly face? Babies in the neonatal intensive care unit cling to moments like that, but sometimes parents and nurses can't be there to offer the constant reassurance. That's where Pat Rice comes in. He is a volunteer cuddler" at the Lucile Packard Children's Hospital Stanford. He and his wife, Claire Fitzgerald, have been cuddling babies there for 16 years. His deep voice helps soothe the babies. He joked someone once told him it sounded like a tuba. "Apparently the voice helps make a difference. I don't know why," said Rice. "But I find that it works pretty well." The nurses said that the cuddles have an immediate impact for these infants. It can even be measured. Their blood oxygenation starts to climb, meaning the baby is relaxed and is breathing deeper. The doctors say cuddling leads to better tolerance of pain, more stable body temperature and even stronger vital signs. Fitzgerald and Rice said they often comfort parents whose babies are admitted to the NICU because they can share stories about all the babies they have cuddled who are now home and thriving. Rice said that at his granddaughter's soccer game recently, a little girl came up to him and gave him a big hug - it was a child he had once cuddled in the hospital.
