Analgesic efficacy of adding the IPACK block to a multimodal analgesia protocol for primary total knee arthroplasty.
Peripheral nerve blocks have been integrated into most multimodal analgesia protocols for total knee arthroplasty (TKA). The adductor canal block (ACB) has gained popularity because of its quadriceps muscle sparing. Similarly, local anesthetic injection between the popliteal artery and the posterior capsule of the knee, IPACK block, has been described to provide analgesia to the posterior capsule of the knee with motor-sparing qualities. This prospective randomized controlled trial aimed to assess the analgesic efficacy of adding the IPACK block to our current multimodal analgesic regimen, including the ACB, in patients undergoing primary TKA. ⋯ The IPACK block reduced the incidence of posterior knee pain 6 hours postoperatively.

Randomized Controlled TrialPhysiological and functional responses of water-cooled versus traditional radiofrequency ablation of peripheral nerves in rats.
Several clinical studies have focused on assessing the effectiveness of different radiofrequency ablation (RFA) modalities in pain management. While a direct head-to-head clinical study is needed, results from independent studies suggest that water-cooled RFA (CRFA) may result in longer lasting pain relief than traditional RFA (TRFA). The primary purpose of this study was, therefore, to investigate in a preclinical model, head-to-head differences between the two RFA technologies. ⋯ This study shows that CRFA has greater energy output, as well as more pronounced structural and functional changes elicited on the peripheral nerves compared with TRFA. While these preclinical data will need to be confirmed with a large clinical randomized controlled trial, we are encouraged by the direction that they may have set for those trials.

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.

Randomized Controlled TrialBilateral ultrasound-guided thoracic erector spinae plane blocks using a programmed intermittent bolus improve opioid-sparing postoperative analgesia in pediatric patients after open cardiac surgery: a randomized, double-blind, placebo-controlled trial.
Postoperative pain after pediatric cardiac surgery is usually treated with intravenous opioids. Recently, the focus has been on postoperative regional analgesia with the introduction of ultrasound-guided erector spinae plane blocks (ESPBs). We hypothesized that bilateral ESPB with a programmed intermittent bolus (PIB) regimen decreases postoperative morphine consumption at 48 hours and improves analgesia in children who undergo cardiac surgery. ⋯ In pediatric cardiac surgery, the results of this study confirm our hypothesis that bilateral ESPB analgesia with ropivacaine decreases the postoperative morphine consumption at 48 hours and demonstrates better postoperative analgesia compared with a control group. Trial registration number NCT03593642.
