Randomized Controlled Trial
Effects of skin-to-skin contact on autonomic pain responses in preterm infants.
The purpose of this randomized crossover trial was to determine the effects on autonomic responses in preterm infants of longer Kangaroo Care (30 minutes, KC30) and shorter KC (15 minutes, KC15) before and throughout heel stick compared with incubator care (IC). Beat-to-beat heart rate (HR) and spectral power analysis of heart rate variability, low frequency power (LF), high frequency power (HF), and LF/HF ratio were measured in 26 infants. HR changes from Baseline to Heel Stick were significantly less in KC30 and KC15 than in IC, and more infants had HR decrease in IC than in 2 KC conditions. In IC, LF and HF significantly increased from Baseline to Heel Stick and dropped from Heel Stick to Recovery; in 2 KC conditions, no changes across study phases were found. During Heel Stick, LF and HF were significantly higher in IC than in KC30. In all 3 conditions, LF/HF ratio decreased from Baseline to Heel Stick and increased to Recovery; no differences were found between IC and two KC conditions. Both longer and shorter KC before and throughout heel stick can stabilize HR response in preterm infants, and longer KC significantly affected infants' sympathetic and parasympathetic responses during heel stick compared with incubator care. ⋯ This study showed that KC has a significant effect on reducing autonomic pain responses in preterm infants. The findings support that KC is a safe and effective pain intervention in the neonatal intensive care unit.

Randomized Controlled Trial
Efficacy of intrathecally administered dexmedetomidine versus dexmedetomidine with fentanyl in patients undergoing major abdominal cancer surgery.
Most of the clinical experience gained in the use of intrathecal alpha-2- adrenoceptor agonists has been described with clonidine. Human studies using a combination of intrathecal dexmedetomidine and local anesthetics are lacking. ⋯ Dexmedetomidine 5 μg given intrathecally improves the quality and the duration of postoperative analgesia and also provides an analgesic sparing effect in patients undergoing major abdominal cancer surgery. Furthermore, the addition of intrathecal fentanyl 25 μg has no valuable clinical effect.

Randomized Controlled Trial Comparative Study
Stress response and procedural pain in the preterm newborn: the role of pharmacological and non-pharmacological treatments.
Repeated invasive procedures occur routinely in neonates who require intensive care, causing pain at a time when it is developmentally unexpected. Multiple lines of evidence suggest that repeated and prolonged pain exposure alters their subsequent pain processing, long-term development, and behaviour. Primary outcome of this study was to evaluate the reduction of procedural pain induced by "heel-lances" in preterm newborns with three different treatment [administration of fentanyl (FE, 1-2 μg/kg), facilitated tucking (FT), sensorial saturation (SS)]. Secondary outcome was the measurement of the levels of cytokines as markers of stress correlated to pain. A prospective randomized controlled trial (RCT) comparing three different pharmacological or non-pharmacological treatments was performed involving 150 preterm newborn (gestational age 27-32 weeks). No other analgesic treatment was performed during the study. CRIES score was used to evaluate the procedural pain. The results showed that the reduction in the pain score was greater in FE and SS groups than FS group. The differences were statistically significant (p < 0.01). The levels of IL-6, IL-8, and TNF-α were higher in the FT individuals than in the FE or SS-treated infants at 1 day (p < 0.01), at 3 days (p < 0.01), and at 7 days (p < 0.01) of life. ⋯ The findings of this study suggest that FE and SS provide a superior analgesia in preterm neonates during procedural pain. In particular, sensorial saturation seems to be an important non-pharmacological alternative treatment to prevent and reduce the procedural pain in preterm newborn.

Randomized Controlled Trial
Morphine and ketamine is superior to morphine alone for out-of-hospital trauma analgesia: a randomized controlled trial.
We assess the efficacy of intravenous ketamine compared with intravenous morphine in reducing pain in adults with significant out-of-hospital traumatic pain. ⋯ Intravenous morphine plus ketamine for out-of-hospital adult trauma patients provides analgesia superior to that of intravenous morphine alone but was associated with an increase in the rate of minor adverse effects.

Randomized Controlled Trial Multicenter StudyA double-blind, randomized, active-controlled study for post-hemorrhoidectomy pain management with liposome bupivacaine, a novel local analgesic formulation.
This randomized, active-controlled study evaluated the extent and duration of analgesia after administration of liposome bupivacaine (LB), a novel formulation of bupivacaine, compared with bupivacaine HCl given via local infiltration in excisional hemorrhoidectomy. One hundred patients were randomly assigned to receive a single dose of bupivacaine HCl 75 mg (0.25% with 1:200,000 epinephrine) or LB 66, 199, or 266 mg upon completion of hemorrhoidectomy. Postoperative pain intensity was assessed using a numeric rating scale at rest to calculate a cumulative pain score (area under the curve). ⋯ Median time to first opioid use was 19 hours for LB 266 mg versus 8 hours for bupivacaine HCl (P = 0.005). Incidence of opioid-related adverse events was 4 per cent for LB 266 mg compared with 35 per cent for bupivacaine HCl (P = 0.007). Local infiltration with LB resulted in significantly reduced postsurgical pain compared with bupivacaine HCl in patients after hemorrhoidectomy surgery.
