title: Nasogastric tube placement: effects on breathing and sucking in very-low-birth-weight infants.
abstract: Eighteen very-low-birth-weight (VLBW) infants who met study criteria were observed during routinely scheduled feedings, twice in one day, once with a nasogastric (NG) tube and once without, in random order. Breathing and sucking measurements were compared with and without NG tube placement. During the prefeed period, minute ventilation and tidal volume were significantly lower with an NG tube than without the tube. During the continuous sucking (CS) period after commencement of oral feeding, minute ventilation, tidal volume, pulse rate, and oxygen saturation were also lower with the tube. During both CS and subsequent intermittent sucking periods, infants sucked less forcefully and took less formula with the tube. Based on these findings, if VLBW infants have an NG tube in place, clinicians are urged to monitor for breathing compromise, oxygen desaturation, and bradycardia during oral feeding.
