At the Emma Children's Hospital, hundreds of children have to undergo unpleasant and often painful medical procedures every year, such as a lumbar puncture, biopsy, keyhole surgery or the insertion of an intravenous drip. This is very stressful, and that is why these children nowadays receive sedation during such procedures. Sedation literally means lowering the level of consciousness so that these procedures can be carried out without any problems. After all, in anxious children, treatments take longer or even fail, which has not only physical, but also psychological and emotional consequences. It can also lead to psychological trauma and/or avoidance of healthcare at a later age. Naturally, we want to prevent that.
