In recent years, the premature birth rate has increased worldwide. More and more premature babies with a low gestational age and weight survive. In addition to ensuring survival, the focus is now on optimizing the quality of life and the development of premature babies. In this thesis, the question arises as to what effects development-promoting measures have on premature babies. Special attention was paid to the components of pain control, environmental factors, kangaroo method, parental involvement and positioning in premature babies. The literature search was chosen for the methodology in the present bachelor thesis. The search took place in the databases CINAHL, Thieme Online, PubMed, Springer and Google Scholar. The results were presented by critically illuminating the mentioned aspects as well as by recording the effectiveness of the respective interventions on the preterm infants. Here, predominantly a positive influence on the cognitive and motor development of the premature infants could be determined. In addition, more positive responses to stress and pain reaction and a shorter length of stay and a faster weight gain were heard. Except for the components of noise and oral glucose administration, clear effects could be observed in all measures, but it should be noted here that most of the studies are short-term effects. It is important to discuss the long-term effects of development-promoting measures.
