Many patients in the intensive care unit (ICU) suffer from pain and are non-communicative. Therefore, alternative pain measures are necessary. Although behavioral pain measures are available, physiological measures are lacking. The Nociception Level index (NOL™) provides a value from combination of multiple physiological parameters to measure pain and its use in the ICU is new. ⋯ The study procedures with the NOL were found feasible; NOL values could discriminate between nociceptive and non-nociceptive procedures, and values were associated with reference pain measures. Further NOL testing is required in other ICU patient groups and procedures.

Clinical TrialBiopsychosocial baseline values of 15 000 patients suffering from chronic pain: Dutch DataPain study.
Chronic pain affects many adults. To improve our daily practice, we need to understand multidisciplinary approaches, integrated treatment plans and the biopsychosocial context of these patients. To date, almost 15 000 chronic pain patients have been referred to the Maastricht University Pain Center in the Netherlands. ⋯ Based on baseline biopsychosocial values, this study shows the complexity of patients referred to pain centers. Pain management with a biopsychosocial approach in an integrated multidisciplinary setting is indispensable. Above all, adjusted education on chronic pain and attention to its biopsychosocial aspects are deemed necessary.

In previous years numerous acute pain models to investigate the pathophysiological mechanisms of pain and to validate treatment procedures have been described. Due to the specific questions addressed by different trials standardized protocols are often missing. Therefore, the research results obtained are only comparable or reproducible to a limited extent. The transferability of acquired knowledge to clinical pain is limited by the mostly short test duration of already established models. ⋯ The established acute pain model in this study is characterized by the induction of thermal pain stimuli of defined intensity and variable duration. There is no danger of significant thermal tissue damage and the pain was tolerated by all study participants. The pain model can easily be established using a device for quantitative sensory testing.

The objective recording of subjectively experienced pain is a problem that has not been sufficiently solved to date. In recent years, data sets have been created to train artificial intelligence algorithms to recognize patterns of pain intensity. The multimodal recognition of pain with machine learning could provide a way to reduce an over- or undersupply of analgesics, explicitly in patients with limited communication skills. ⋯ Priority should be given to the multimodal approach to the recognition of pain intensity and modality compared with unimodality. Further clinical studies should clarify whether multimodal automated recognition of pain intensity and modality is in fact superior to bimodal recognition.
