This investigation assessed the effect of side-lying position on infant oropharyngeal swallow physiology. Infant modified barium swallow studies (MBS) recordings were retrospectively examined in matched-pairs comparing at-risk infants swallowing in both an upright/cradled position and a side-lying position. Swallow parameters were measured independently and through a consensus coding approach. Infants fed in side-lying position showed a decrease in airway invasion severity as compared with when those same infants were fed in an upright/cradled position ( = .009). Bolus location at the time of swallow initiation was higher when infants were fed in side-lying position as compared with cradle position ( = .024), representing decreased risk of airway invasion. Infants fed in side-lying position demonstrated fewer swallows per breaths ( = .032). This pilot study validates the need for additional research to further define the mechanisms related to this improvement, and to determine how diagnosis and medical stability moderate these findings.
本研究评估了侧卧位对婴儿口咽吞咽生理的影响。将有风险的婴儿在仰卧/抱姿和侧卧位两种姿势下吞咽时的改良钡剂吞咽研究（MBS）记录进行配对比较，对其进行回顾性检查。通过独立和共识编码方法测量吞咽参数。与仰卧/抱姿相比，婴儿在侧卧位时气道侵入的严重程度降低（ =.009）。与抱姿相比，婴儿在侧卧位时吞咽起始时的食团位置更高（ =.024），这代表气道侵入的风险降低。与仰卧/抱姿相比，婴儿在侧卧位时每呼吸的吞咽次数更少（ =.032）。这项初步研究验证了需要进一步研究以进一步确定与这种改善相关的机制，并确定诊断和医学稳定性如何调节这些发现。
