Enhanced recovery after surgery (ERAS) protocols incorporating multimodal analgesia (MMA) have become increasingly popular for breast cancer surgery. Our study evaluated an ERAS approach that combined nonintubated general anesthesia with thoracic paravertebral block (TPVB) as part of the MMA and compared it to traditional general anesthesia (GA). Postoperative outcomes were assessed using numerical rating scale (NRS) pain scores, total analgesic consumption, and nausea and vomiting (PONV). ⋯ Nonintubated general anesthesia with TIVA and MMA using TPVB is a viable and safe alternative for breast cancer surgery. It results in reduced pain scores and analgesic needs compared with conventional GA, with PONV outcomes comparable to those managed with standard intravenous medications.

Integrating regional blocks into Enhanced Recovery After Surgery protocols for cesarean delivery: optimizing postoperative recovery.
This review aims to synthesize the current literature on the use of regional blocks to enhance and optimize postoperative recovery after cesarean delivery, highlighting key strategies, challenges, and emerging trends. ⋯ Managing pain after cesarean delivery continues to pose a significant challenge. The overall prevalence of acute postoperative pain remains high (58%) and, even when strict adherence to established guidelines is ensured, approximately 25% of patients report inadequate pain control. Within a multimodal analgesic framework, when neuraxial morphine - still considered the gold standard - is not an option, the use of peripheral nerve and fascial plane blocks has demonstrated clear benefits. Recent literature suggests that quadratus lumborum block may serve as a promising alternative to intrathecal morphine for women who cannot tolerate opioids. Additionally, incorporating certain regional techniques alongside neuraxial morphine may further improve postoperative analgesia, especially for patients at high risk of severe postoperative pain and those who have contraindications to other analgesic modalities.

Breast surgery is frequently associated with significant acute postoperative pain, necessitating effective pain management strategies. Both thoracic paravertebral block (PVB) and interpectoral plane and pectoserratus plane (IP+PS) blocks have been used to relieve pain after breast surgery. ⋯ PVB and IP+PS blocks offer comparable analgesic efficacy and opioid-sparing effects after breast surgery, with no meaningful differences in 24-h MME consumption, pain scores, or PONV incidence.

ReviewTen years of transitional pain service research and practice: where are we and where do we go from here?
Chronic postsurgical pain (CPSP) is a prevalent yet unintended consequence of surgery with substantial burdens to the individual and their family, the healthcare system, and society at large. The present article briefly reviews the evidence for transitional pain services (TPSs) that have arisen in an effort to prevent and mange CPSP and persistent opioid use, and provides an update on recent novel risk factors for CPSP. Available evidence from one randomized controlled trial (RCT) and three non-randomized cohort studies suggests that TPS treatment is associated with better opioid use outcomes, including fewer opioid tablets prescribed at discharge, better opioid weaning results, a lower incidence of new-onset chronic opioid use, and lower consumption of opioids even at later time points up to 1 year after surgery. ⋯ While these preliminary studies are generally positive, large-scale, RCTs are needed to provide a more definitive picture of whether TPSs are effective in reducing opioid consumption and improving pain and mental health outcomes in the short and long term. With the expansion of TPSs across North America and globally, perioperative care focused on reducing the transition to pain chronicity has the potential to help millions of patients. With additional evidence from well-controlled RCTs, TPSs are well poised to continue to evolve and strengthen the role of multidisciplinary care teams in the immediate postdischarge period and beyond.

ReviewMachine learning research methods to predict postoperative pain and opioid use: a narrative review.
The use of machine learning to predict postoperative pain and opioid use has likely been catalyzed by the availability of complex patient-level data, computational and statistical advancements, the prevalence and impact of chronic postsurgical pain, and the persistence of the opioid crisis. The objectives of this narrative review were to identify and characterize methodological aspects of studies that have developed and/or tested machine learning algorithms to predict acute, subacute, or chronic pain or opioid use after any surgery and to propose considerations for future machine learning studies. Pairs of independent reviewers screened titles and abstracts of 280 PubMed-indexed articles and ultimately extracted data from 61 studies that met entry criteria. ⋯ We identified variability in sample size, number and type of predictors, and how outcome variables were defined. Patient-reported predictors were highlighted as particularly informative and important to include in such machine learning algorithms, where possible. We hope that findings from this review might inform future applications of machine learning that improve the performance and clinical utility of resultant machine learning algorithms.
