“…Previous studies found that when infants suck on a paci®er, fussing and crying is decreased (Field & Goldson, 1984;DiPietro, Cusson, Caughy, & Fox, 1994) as well as HR (Woodson & Hamilton, 1988). In our studies, HR did not decrease with paci®er sucking.…”

This study examined the effects of sucking on a pacifier immediately before feeding on cardiovascular responses to feeding. Twenty-eight bottle-feeding infants were studied at 12 to 40 hr of age. Blood pressure and heart rate measurements were made during three periods: Period 1-while infants rested in their cribs before a regularly scheduled feeding, Period 2-while being held by the feeder immediately before feeding, and Period 3-during the first 3 to 5 min of feeding. Half of the infants were given a pacifier during Period 2. Blood pressures and heart rates increased across the periods; however, increases in systolic blood pressure during feeding were reduced for the group of infants given a pacifier prior to feeding. We suggest that cardiovascular responses to feeding in infants are comprised of multiple elements. Most of the systolic blood pressure responses to feeding are elicited by sucking whereas the heart rate response is dependent on both sucking and nutrient intake.

“…To our knowledge, this aspect has not been investigated before. Though several reports exist in the literature describing the influence of NNS on HR and peripheral oxygenation [17,[51][52][53] , studied mainly during painful procedures [51] or in gavage-fed preterm infants [17,51,52] , these data are not comparable to ours since these studies were not carried out during sleep and did not differentiate between suckling bursts and rest periods.…”

Background: Pacifier use has been postulated to decrease the risk of sudden infant death syndrome (SIDS). The responsible mechanisms are, however, unclear. Objectives: Since little is known about the non-nutritive sucking (NNS) habits of infants during sleep, we investigated NNS patterns and changes of physiological parameters during NNS in sleeping infants. Methods: Polygraphic recordings were performed in 12 infants with a median age of 55 days (range 7–82) who regularly used a pacifier during sleep. Episodes of active suckling (bursts) and quiescent periods were differentiated by video observations. We evaluated the time of suckling in relation to the total time of pacifier use, the median number of bursts per min, the median duration of single bursts and the median interval between 2 sequent bursts. In 48 randomly selected bursts, we additionally analyzed changes in heart rate, respiratory frequency and oxygen saturation compared to the 10-second period preceding the burst. Results: Median sleep time with a pacifier held in mouth was 31.3 min (13.0–117.6), of which 15.5% (6.4–36.7%) was spent with active suckling. The median number of bursts per min was 2.2 (1.2–4.5). The median duration of a burst was 3 s (1–22) and the median interval between 2 bursts was 10 s (1–1,434). Heart rate, respiratory frequency and oxygen saturation did not change significantly during suckling bursts. Conclusions: This pilot study presents important data for sucking habits in pacifier users which may provide a basis for further investigations concerning the efficacy of pacifiers in SIDS prophylaxis.

“…In addition to the soothing and self-calming effects pacifier use has with full-term infants, there are additional benefits for LBW infants. These benefits include energy conservation necessary for oxygenation and growth as indicated by a decreased gastrointestinal transit time (Marchini, Lagercrantz, Feuerberg, Winberg, & Uvnas-Moberg, 1987;Widstrom et al, 1988), possible protection against necrotizing enterocolitis (Pickler & Terrell, 1994), increased weight gain (Measel & Anderson, 1979), earlier oral feedings (Field et al, 1982;Measel & Anderson, 1979), modulation of behavioral state (Gill, Behnke, Colon, McNeely, & Anderson, 1988;Pickler, Higgins, & Crummette, 1993), decreased heart rate (Miller & Anderson, 1993;Woodson & Hamilton, 1988) soothing of Infants interact with their environment in the process of negotiating the developmental process.…”
