Decreasing Perioperative Opiate Use During Pancreaticoduodenectomy Using Transversus Abdominus Plane Blocks: A Review of the Literature.

Background: Pancreatoduodenectomy is a highly complex surgical procedure associated with high postoperative morbidity and mortality. Treatment of postoperative pain is crucial to preventing chronic pain and further complications. Opioids are the leading treatment modality for acute postoperative pain for all surgical procedures in the US, contributing to the opioid epidemic, a crisis causing death and lifelong impairment in many patients.

Preoperative transversus abdominis plane block decreases intraoperative opiate consumption during minimally invasive cholecystectomy.

Background: The ongoing epidemic of prescription opiate abuse is one of the most pressing health issues in the United States today. Consequently, analgesic adjuncts, such as multimodal drug regimens and regional anesthetic blocks (like transversus abdominis plane (TAP) block), have been introduced to the perioperative period in hopes of decreasing postoperative opiate use. However, the effect of these interventions on intraoperative opiate use has not been examined.

Effect of perioperative cognitive behavioural therapy on chronic post-surgical pain among breast cancer patients with high pain catastrophising characteristics: protocol for a double-blinded randomised controlled trial.

Background: Surgery is regarded as the primary treatment for breast cancer. Chronic post-surgical pain (CPSP) is a recognised complication after breast cancer surgery, and it is estimated to affect 20-30% of women. Pain catastrophizing has emerged as one of the most influential psychological variables associated with CPSP.

Preoperative transversus abdominis plane block decreases intraoperative opiate use during pancreatoduodenectomy.

Background: Multimodal analgesia and regional anesthetic blocks, such as transversus abdominis plane (TAP) block, decrease postoperative opiate consumption but their effect on intraoperative opiates is unknown.

Methods: This was a retrospective review of patients undergoing pancreatoduodenectomy between June 2018 and February 2021, in which perioperative data, operative times, and medication administration data were collected. Intraoperative opiate use was calculated in total morphine equivalent doses (MED) for each patient and adjusted for operative time.

Peer review for the Canadian Journal of Anesthesia in 2016 and 2017: a retrospective analysis by reviewer and author gender.

Purpose: Our objectives were to analyze the gender of reviewers of all manuscripts submitted to the Canadian Journal of Anesthesia in 2016 and 2017. We hypothesized that the percentage of reviewers who were women would be ≤ 25%, an estimate based on the expert opinion estimates of the investigators and much less than the overall proportion of women in medicine.

Methods: Reviewers and authors of manuscripts submitted between 1 January 2016 and 31 December 2017 were coded as "woman", "man", or "unknown gender" according to an internet search of the person's name, address, medical registration, and/or first name.

Severe acute pain and persistent post-surgical pain in orthopaedic trauma patients: a cohort study.

Background: We conducted a cohort study of adult patients presenting for orthopaedic trauma surgery at a statewide trauma centre, with the aims of determining (i) the incidence and risk factors for severe acute pain in the PACU, and (ii) the incidence and risk factors for persistent post-surgical pain at 3 months.

Methods: Data were collected before operation, in the PACU, 72 h after surgery and 3 months after surgery, and included numerical rating scale (NRS) scores for pain, and modified Brief Pain Inventory-Short Form, Kessler Psychological Distress Scale, World Health Organization Disability Assessment Schedule, and Pain Catastrophizing Scale scores.

Results: Severe acute pain in the PACU was reported by 171 (56%; 95% confidence interval [CI]: 51%, 62%) of the 303 included patients.
