Multicenter Study Clinical Trial
10 kHz SCS for chronic postsurgical pain: Results from a 12-month prospective, multicenter study.
Chronic postsurgical pain (CPSP) can be caused by peripheral nerve injury (PNI) resulting from surgical procedures and has a significant neuropathic component. This prospective, single-arm study was conducted to document the effectiveness of 10-kHz spinal cord stimulation (10-kHz SCS) as a treatment for patients with CPSP. ⋯ 10-kHz SCS is effective and tolerated in patients with CPSP, and further study of its clinical application in this population is warranted.

Single nucleotide polymorphisms (SNPs) of the voltage-gated sodium channel alpha subunit gene (SCN9A) have been associated with pain in various settings. The aim of this study was to investigate the association of the SNPs to evaluate the influence of common gene variants on chronic postoperative pain (CPSP) and other related pain variables in a cohort of patients who underwent a scheduled hysterectomy. ⋯ Our results showed that SCN9A polymorphisms could play a role in acute pain perception and the susceptibility to chronic pain.

Abdominal and peritoneal pain after surgery is common and burdensome, yet the lack of standardized diagnostic criteria for this type of acute pain impedes basic, translational, and clinical investigations. The collaborative effort among the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks, American Pain Society, and American Academy of Pain Medicine Pain Taxonomy (AAAPT) provides a systematic framework to classify acute painful conditions. Using this framework, a multidisciplinary working group reviewed the literature and developed core diagnostic criteria for acute abdominal and peritoneal pain after surgery. ⋯ Additional investigation regarding the validity and reliability of this framework will facilitate its adoption in research that advances our comprehension of mechanisms, deliver better treatments, and help prevent the transition of acute to chronic pain after surgery in the abdominal and peritoneal region. PERSPECTIVE: Using AAAPT, we present key diagnostic criteria for acute abdominal and peritoneal pain after surgery. We provide a systematic classification using 5 dimensions for abdominal and peritoneal pain that occurs after surgery, in addition to 4 specific surgical procedures: cesarean delivery, cholecystectomy, colorectal surgical procedures, and pancreas resection.

Postdischarge Pain Management After Thoracic Surgery: A Patient-Centered Approach.
Postoperative analgesia is paramount to recovery after thoracic surgery, and opioids play an invaluable role in this process. However, current 1-size-fits-all prescribing practices produce large quantities of unused opioids, thereby increasing the risk of nonmedical use and overdose. This study hypothesized that patient and perioperative characteristics, including 24-hour before-discharge opioid intake, could inform more appropriate postdischarge prescriptions after thoracic surgery. ⋯ Assessment of 24-hour before-discharge opioid intake may inform patient requirements after discharge. Opioid prescriptions after thoracic surgery can thereby be targeted on the basis of anticipated needs.

Comparative StudyIntra-operative ketorolac 15 mg versus 30 mg for analgesia following cesarean delivery: a retrospective study.
Ketorolac is a nonsteroidal anti-inflammatory drug used as part of multimodal analgesia in women undergoing cesarean delivery. The lowest effective dose of ketorolac that best optimizes analgesia without increasing side effects is unclear. We performed this retrospective study to compare the analgesic efficacy of 15 mg or 30 mg ketorolac administered intra-operatively to our obstetric population. ⋯ There was no difference in opioid use between patients receiving either a 15 mg or a 30 mg dose of ketorolac given intra-operatively for postoperative analgesia following cesarean delivery.
