Randomized Controlled Trial Comparative Study
Does breastfeeding reduce acute procedural pain in preterm infants in the neonatal intensive care unit? A randomized clinical trial.
Managing acute procedural pain effectively in preterm infants in the neonatal intensive care unit remains a significant problem. The objectives of this study were to evaluate the efficacy of breastfeeding for reducing pain and to determine if breastfeeding skills were altered after this treatment. Fifty-seven infants born at 30-36 weeks gestational age were randomized to be breastfed (BF) or to be given a soother during blood collection. ⋯ Lower BIIP scores during the Lance/squeeze were associated significantly with more mature sucking patterns (r=-0.39, P<0.05). Breastfeeding during blood collection did not reduce pain indices or interfere with the acquisition of breastfeeding skills. Exploratory analyses indicate there may be benefit for infants with mature breastfeeding abilities.

ReviewPharmacokinetic-pharmacodynamic modeling in acute and chronic pain: an overview of the recent literature.
In acute and chronic pain, the objective of pharmacokinetic-pharmacodynamic (PKPD) modeling is the development and application of mathematical models to describe and/or predict the time course of the pharmacokinetics (PK) and pharmacodynamics (PD) of analgesic agents and link PK to PD. Performing population PKPD modeling using nonlinear mixed effects modeling allows, apart from the estimation of fixed effects (the PK and PD model estimates), the quantification of random effects as within- and between-subject variability. Effect-compartment models and mechanism-based biophase distribution models that incorporate drug-association and -dissociation kinetics are applied in PKPD modeling of pain treatment. ⋯ Mixture models do not necessarily need to take PK data into account and allow the objective differentiation of measured responses to analgesics into specific response subgroups, and as such, may play an important role in analyzing Phase I and II analgesia studies. Appropriate application of PKPD modeling leads to the improvement of current therapeutics with respect to dose design and outcome, understanding the interaction of analgesics within complex chronic pain disease processes and may play an important role in drug development. In the current article, novel observations using the aforementioned techniques on opioids, NSAIDs, epidural analgesia, ketamine and GABA-ergic drugs in acute and chronic pain are discussed.

Fibromyalgia (FM) is a mysterious pain syndrome with progressive and widespread pain, explicit areas of tender points, stiffness, sleep disturbance, fatigue, and psychological distress without any obvious disease. FM is commonly perceived as a condition of central pain and sensory augmentation. There are documented functional abnormalities in pain and sensory processing in FM. ⋯ Pre-emptive analgesia and pro-active treatment may offer the momentum for acute pain control based on model of central sensitization and pain in FM. This review article on FM appraises the modern practice of multimodal therapy focus on both acute and chronic pain management. Meanwhile, the evolving nonpharmacological approach is summarized and stressed as an essential component of integrated care in FM.
