Randomized Controlled Trial
Effect of adductor canal block combined with infiltration between the popliteal artery and posterior capsular of the knee on chronic pain after total knee arthroplasty: a prospective, randomized, double-blind, placebo-controlled trial.
Total knee arthroplasty (TKA) is accompanied by severe postoperative pain, which is reported to be an important cause of chronic pain. Ultrasound-guided adductor canal block (ACB) combined with infiltration between the popliteal artery and posterior capsular of the knee (IPACK) has been proven to have a better effect on relieving acute pain after TKA. However, whether it has a significant effect on the incidence of chronic pain after TKA has not been reported. This trial was designed to investigate the effect of ultrasound-guided ACB combined with IPACK on the incidence and intensity of chronic pain after TKA. ⋯ In the context of multimodal analgesia protocols, ACB combined with IPACK before surgery decreases the incidence and intensity of chronic pain 3 months after TKA compared with placebo injection. In addition, it reduces the NRS scores, whether at rest or during mobilization, and improves knee function within 24 hours after TKA.

Pro-Con Debate: Anesthesiologists Should Be Responsible for Treating Preoperative Anemia.
In this Pro-Con commentary article, we discuss whether anesthesiologists should be responsible for treating preoperative anemia. This debate was proposed based on the article published in this issue of Anesthesia & Analgesia by Warner et al, which is an advisory on managing preoperative anemia endorsed by both the Society of Cardiovascular Anesthesiologists and the Society for Advancement of Patient Blood Management. ⋯ Even if we agree that preoperative anemia is worth treating before surgery, the question remains who should be responsible for doing so, and therein lies the reason for this Pro-Con debate. Should it be the responsibility of the anesthesiologist, or not? Let the readers decide.

Posterior quadratus lumborum block versus intrathecal morphine analgesia after scheduled cesarean section: a prospective, randomized, controlled study.
During the postoperative period of elective cesarean section, intrathecal morphine is effective in the multimodal analgesic regimen, but can cause significant adverse effects. Bilateral posterior quadratus lumborum block could be alternatively used. The aim of this study was to compare efficacy and safety of both strategies as part of a multimodal analgesic regimen. ⋯ There was no statistical difference in the mean cumulative morphine dose at 24-hour between groups (posterior quadratus lumborum block group, 13.7 (97.5% CI 10.4 to 16.9) mg; intrathecal morphine group, 11.1 (97.5% CI 8.4 to 13.8) mg, p=0.111). Pain scores did not show any difference between groups, excepted at 6 hours for the pain at cough/movement in favor of the posterior quadratus lumborum block group (p=0.013). A better recovery quality was observed at 24 hours in the posterior quadratus lumborum block group (p=0.009). Pruritus was more frequent in intrathecal morphine group parturients (35% vs 2%) CONCLUSIONS: No difference in cumulative morphine dose at 24 hours was observed in posterior quadratus lumborum block group compared with intrathecal morphine group. Posterior quadratus lumborum block can be considered an alternative to intrathecal morphine in cesarean postoperative analgesia, especially in cases of intolerance to morphine.
