Appropriate pain management is essential to improve the postoperative recovery after total hip arthroplasty (THA). Various case reports have indicated that anterior quadratus lumborum block (QLB) provides effective postoperative analgesia in lower limb surgeries. However, few randomized controlled trials have confirmed the efficacy of anterior QLB for lower limb surgeries. The aim of this single-center, double-blind, randomized controlled trial is to confirm the efficacy of anterior QLB for postoperative recovery after THA. ⋯ The results of our study will reveal whether anterior QLB is effective for postoperative recovery after THA.

Postoperative inadequate analgesia following video-assisted thoracoscopic surgery (VATS) is a common and significant clinical problem. While genetic polymorphisms may play role in the variability of postoperative analgesia effect, few studies have evaluated the associations between genetic mutations and inadequate analgesia after single-port VATS. ⋯ We identified that SNPs in SCN9A, SCN10A, and SCN11A play a role in the postoperative inadequate analgesia after single-port VATS. Although future larger and long-term follow up studies are warranted to confirm our findings, the results of the current study may be utilized as predictors for forecasting postoperative analgesic effect for patients receiving this type of surgery.

Randomized Controlled TrialEffect of Eye Masks on Pain and Sleep Quality in Patients Undergoing Cardiac Surgery: A Randomized Controlled Trial.
Impaired sleep is a common complaint among patients undergoing major surgery and may be a contributing factor in postoperative pain. The provision of eye masks to patients after cardiac surgery may reduce postoperative pain through improvements in sleep quality. ⋯ Nocturnal eye masks are a simple, low-risk, low-cost intervention that may contribute to reductions in perceived pain in cardiac surgery patients.

What’s the relevance?
Remifentanil’s ultrashort-acting kinetics have driven its growth as a reliable technique for maintaining intraoperative analgesia. It is now one of the most widely used synthetic opioids in anesthesia.
However these unique pharmacological characteristics are associated with both Opioid Induced Hyperalgesia and Acute Opioid Tolerance, and possibly increase the risk of chronic pain after surgery.
Details:
Niedermayer and team performed a large, multicenter, propensity-matched observational study of remifentanil use during intra-abdominal surgery, and its association with postoperative pain in the PACU. Importantly the patients receiving epidural analgesia in addition to TIVA GA were also included. Volatile GA was excluded.
Among 16,420 patients meeting inclusion criteria, 3,652 GA/TIVA patients received remifentanil and were matched to 3,318 controls, and 829 GA/epi received remifentanil, being matched to 631 controls. Mean remifentanil infusions rates were 0.11 and 0.13 mcg/kg/min for non-EA and EA groups respectively.
They showed:
Among GA-only patients, remifentanil was associated with higher PACU pain scores (both on arrival and discharge), greater analgesic requirements and more PONV – however there was no decrease of either time-to-extubation or PACU discharge.
Interestingly, the epidural analgesia cohort also showed higher PACU pain scores when receiving remifentanil.
The rapid nociceptive changes due to remifentil are well known, however real clincial consequences remain unclear. This large observational study highlights the detrimental analgesic effects of remifentanil in the most immediate post-op period, reminding anesthetists and anesthesiologists that gold-standard intraoperative analgesia may come at a cost.

Meta Analysis
Intraoperative methadone administration and postoperative pain control: a systematic review and meta-analysis.
Postoperative pain is not adequately managed in greater than 40% of surgical patients and is a high priority for perioperative research. In this meta-analysis, we examined studies comparing postoperative opioid consumption and pain scores in surgical patients who received methadone by any route vs those who received another opioid by any route. Studies were identified from PubMed, Cochrane, Web of Science, EMBASE, and Scopus from January 1966 to November 2018. ⋯ The results demonstrate that surgical patients who received intraoperative methadone had lower postoperative opioid consumption, generally reported lower pain scores and experienced better satisfaction with analgesia. However, these advantages need to be weighed carefully against dangerous risks with perioperative methadone, specifically respiratory depression and arrhythmia. Future studies should explore logistics, safety, and cost effectiveness.
