Respiration and suck are gestational age-dependent reflexes modulated in the brain stem. To determine if the suck reflex pattern could be used to predict apnea, the relationship between the two was examined in 28 neonates. The suck reflex was quantified with respect to burst-pause rhythm, amplitude of negative suck pressure, and synchrony of the negative-positive pressure. Apneas were counted 5 days prior to and following measurement of the suck reflex pattern. Increasing gestational age correlated with a lower frequency of apnea (P < .01) and higher suck scores (P < .01). A mature suck reflex pattern, however, failed to predict the occurrence of apnea.
呼吸和吸吮是受脑干调节的与胎龄相关的反射。为了确定吸吮反射模式是否可用于预测呼吸暂停，对28名新生儿的两者关系进行了研究。从爆发-暂停节律、负吸吮压力幅度和正负压力同步性方面对吸吮反射进行量化。在测量吸吮反射模式之前和之后的5天内统计呼吸暂停情况。胎龄增加与呼吸暂停频率降低（P < .01）和吸吮得分升高（P < .01）相关。然而，成熟的吸吮反射模式未能预测呼吸暂停的发生。
