Multicenter Study[Respiratory and circulatory parameters as indicators of the postoperative analgesic demand in newborns and infants].
Due to immature cognitive functions, infants are unable to communicate their pain perception verbally. To assess postoperative analgesic demand, the anaesthetist has to rely on observational techniques. Generally, pain expression is considered to be a multidimensional phenomenon consisting of physiological, motor-reflex and behavioural patterns. The majority of observational approaches to pain assessment in infants use the behavioural dimension only, regardless of the fact that pain perception might contribute substantially to the stress response. The aim of this study is to evaluate, whether sensitivity and specificity of a behavioural pain scale (CHIPPS [1]) can be improved by adding physiological measures, especially those representing the stress response. ⋯ Despite the multidimensional approach and the corresponding multivariate analyses, a unidimensional scale consisting of behavioural items was found to be a valid indicator of an postoperative analgesic demand. Due to the lack of diagnostic properties and difficulties to obtain sound values even under research conditions, physiological measurements like blood pressure, respiratory rate and heart rate are not suitable for the assessment of a postoperative analgesic demand in infants, neither for clinical nor for research purposes.
