Abstract

Purpose: The purpose of this study was to determine effectiveness of a midliner positioning system (MPS, Tortle Midliner) for preventing dolichocephaly. Methods: This was a nonrandomized, prospective study of 30 premature infants (study cohort, SC) using an MPS compared with a retrospective study cohort (RSC) of 65 infants who received standard of care intervention. Results: RSC baseline cranial index (CI) of 80% and final CI of 77% significantly decreased over an average 5.5 weeks (P <.0001). The SC baseline CI and the final CI were both 79% over an average 5.7 weeks, indicating no significant difference between CI measures (P =.6). Gestational age, birth weight, reflux, time on continuous positive airway pressure, and time in a supine position were not associated with dolichocephaly. Conclusions: The SC developed less cranial molding (ie, had greater CI), compared with the RSC. A larger randomized study is needed to recommend routine use of MPS for prevention and/or treatment of cranial molding in premature infants.
