This study examined the relationship between the number of sucks in the first nutritive suck burst and feeding outcomes in preterm infants. The relationships of morbidity, maturity, and feeding experience to the number of sucks in the first suck burst were also examined.
A non-experimental study of 95 preterm infants was used. Feeding outcomes included proficiency (percent consumed in first 5 min of feeding), efficiency (volume consumed over total feeding time), consumed (percent consumed over total feeding), and feeding success (proficiency >or=0.3, efficiency >or=1.5 mL/min, and consumed >or=0.8). Data were analyzed using correlation and regression analysis.
There were statistically significant positive relationships between number of sucks in the first burst and all feeding outcomes-proficiency, efficiency, consumed, and success (r=0.303, 0.365, 0.259, and tau=0.229, P<.01, respectively). The number of sucks in the first burst was also positively correlated to behavior state and feeding experience (tau=0.104 and r=0.220, P<.01, respectively). Feeding experience was the best predictor of feeding outcomes; the number of sucks in the first suck burst also contributed significantly to all feeding outcomes. The findings suggest that as infants gain experience at feeding, the first suck burst could be a useful indicator for how successful a particular feeding might be.
本研究探讨了早产婴儿首次营养性吸吮阵发中的吸吮次数与喂养结果之间的关系。还研究了发病率、成熟度和喂养经验与首次吸吮阵发中吸吮次数的关系。
采用对95名早产婴儿的非实验性研究。喂养结果包括熟练程度（喂养前5分钟摄入的百分比）、效率（总喂养时间内摄入的量）、摄入量（总摄入量的百分比）和喂养成功率（熟练程度≥0.3、效率≥1.5毫升/分钟且摄入量≥0.8）。使用相关性和回归分析对数据进行分析。
首次阵发中的吸吮次数与所有喂养结果——熟练程度、效率、摄入量和成功率之间存在统计学上显著的正相关关系（r分别为0.303、0.365、0.259和tau = 0.229，P <.01）。首次阵发中的吸吮次数也与行为状态和喂养经验呈正相关（tau分别为0.104和r = 0.220，P <.01）。喂养经验是喂养结果的最佳预测指标；首次吸吮阵发中的吸吮次数对所有喂养结果也有显著贡献。研究结果表明，随着婴儿获得喂养经验，首次吸吮阵发可能是特定喂养成功程度的一个有用指标。
