Peroxisome proliferator-activated receptor-gamma agonist rosiglitazone attenuates postincisional pain by regulating macrophage polarization.
Acute inflammation triggered by macrophage infiltration to injured tissue promotes wound repair and may induce pain hypersensitivity. Peroxisome proliferator-activated receptor γ (PPAR)γ signaling is known to regulate heterogeneity of macrophages, which are often referred to as classically activated (M1) and alternatively activated (M2) macrophages. M1 macrophages have considerable antimicrobial activity and produce a wide variety of proinflammatory cytokines. ⋯ Moreover, transplantation of rosiglitazone-treated peritoneal macrophages into the incisional sites significantly attenuated hyperalgesia. We speculate that local administration of rosiglitazone significantly alleviated the development of postincisional pain, possibly through regulating macrophage polarity at the inflamed site. PPARγ signaling in macrophages may be a potential therapeutic target for the treatment of acute pain development.

Randomized Controlled Trial
Effectiveness of oral sucrose for pain management in infants during immunizations.
This study examined the effects of oral sucrose as an analgesic agent during routine immunization for infants at 2, 4, and 6 months of age. A sample of 113 healthy infants were recruited from three ambulatory clinics and randomly assigned to one of three treatment groups. ⋯ No significant difference was found among the different age groups with the different treatments for pain as measured with the FLACC scores and crying time. Consolability factors are felt to have some influence.

The objectives were to describe the dose of opioids and incidence of titration for management of acute pain in emergency department patients and, secondarily, to assess the association between change in pain and dose. ⋯ Analgesic practice did not conform to recommended doses or regimens. There was only a weak association between change of pain and dose in the range of doses given. These findings suggest that oligoanalgesia continues to be a problem despite improvements over the past 20 years.

The majority of patients who undergo surgery will require drug therapy for the management of acute postsurgical pain. Effective control of acute postsurgical pain is essential for the patient not only in the short term but also in the long term to prevent the development of chronic pain, which can occur if early acute pain is prolonged. Currently, opioid analgesics are widely used for the management of acute postsurgical pain. ⋯ Elderly patients and those with comorbidities (e.g., obesity, sleep apnea, respiratory disease, urinary disorders) may be particularly vulnerable to ORADE development. Both hospital costs and length of stay are increased in patients with an ORADE versus those without an ORADE. Strategies to reduce the use of opioids after surgery are likely to result in positive outcomes by reducing the incidence of ORADEs and, as a result, reducing treatment costs associated with surgery and improving patient care.
