BackgroundAssessing pain in premature babies is difficult because of their limited capacities to communicate. The aim of this study was to recognize manifestations of acute and chronic pain or, on the contrary, of well-being state, and to validate a "pain scale" for premature babies.Population And MethodsPremature babies less than 28 days of age (most of them less than 32 weeks of gestational age) were carefully observed during their stay in a neonatal intensive care unit by nurses, physicians, physiotherapists and a psychiatrist. All signs and symptoms were collected during situations a priori painful and compared to the behavior of the well-being states. Photographs and videofilms were also analysed.ResultsFive items, scored from 0 to 4, were established, based on facial activity, movements and posture of the body, quality of sleep, relationship with the examiner, and efficacy of measures of comforting. These items permitted to describe four patterns corresponding to 1: well-being status, 2: acute pain, 3 and 4: durable pain or discomfort either through clinical picture of irritability or motionlessness. A strict concordance of scores for the five items between the different examiners was found in 80% of the 50 babies studied. The sensibility of the scale (studied in 12 babies) appeared accurate (77% of variation of the scores during hospitalization).ConclusionsAn objective assessment of pain and discomfort in premature babies can be made using a "pain scale" useful for care and therapeutic decisions.
