Background Pain, a persistent problem in critically ill patients, adversely affects outcomes. Despite recommendations, no evidence-based nonpharmacological approaches for pain treatment in critically ill patients have been developed. Objectives To investigate the effects of a multimodal integrative intervention on the incidence of pain and on secondary outcomes: intensity of pain, hemodynamic indices (systolic and mean arterial pressure, heart rate), anxiety, fear, relaxation, optimism, and sleep quality. Methods A randomized, controlled, double-blinded repeated-measures trial with predetermined eligibility criteria was conducted. The intervention included relaxation, guided imagery, moderate pressure massage, and listening to music. The primary outcome was incidence of pain (score on Critical Care Pain Observation Tool > 2). Other outcomes included pain ratings, hemodynamic measurements, self-reported psychological outcomes, and quality of sleep. Repeated-measures models with adjustments (baseline levels, confounders) were used. Results Among the 60 randomized critically ill adults in the sample, the intervention group experienced significant decreases in the incidence (P = .003) and ratings of pain (P < .001). Adjusted models revealed a significant trend for lower incidence (P = .002) and ratings (P < .001) of pain, systolic arterial pressure (P < .001), anxiety (P = .01), and improved quality of sleep (P = .02). Conclusion A multimodal integrative intervention may be effective in decreasing pain and improving painrelated outcomes in critically ill patients. (American Journal of Critical Care. 2018; 27:172-185) EFFECTS OF Unrelieved pain is common among ICU patients and may compromise outcomes, by contributing to unstable hemodynamic parameters, hypercatabolism, hyperglycemia, infections, delirium, and posttraumatic stress. 2 Pain in ICU patients may also be part of a vicious circle implicating anxiety 3 and insomnia. 4 Moreover, pain has been linked to the post-ICU syndrome 5 and may become chronic in survivors, a situation associated with poor quality of life and poor psychological and physiological outcomes.
6Management of pain in patients with a critical illness is challenging.7 Opioids, the drug class of choice, are associated with marked side effects, including respiratory depression, hypotension, decreased gastrointestinal motility, delirium, and higher costs due to increased use of resources and prolonged stay in the ICU.8 Nociception, the perception of painful stimuli, entails a complex interaction among sensory, affective, and social components.9 Moreover, anxiety, fear, and negative expectations are common in critically ill patients and may contribute to heightened perception of pain.10 Thus, the multifactorial nature of ICU pain calls for approaches that address both physiological and psychosocial responses to pain. Current guidelines highlight the need to test and implement nonpharmacological strategies for pain treatment in critically ill patients.2 Interventions that elicit a relaxation ...
