Abstract PDF: Background
Quadratus lumborum (QL) block is used for multimodal analgesia following abdominal surgery. We introduced an ultrasound-guided QL block to treat postoperative pain for ileostomy closure. This study aimed to investigate the analgesic efficacy of the QL block compared to placebo after ileostomy closure.
Methods
Fifty-seven patients undergoing elective ileostomy closure were randomized (1:1) to the placebo or QL block group in this double-blind randomized controlled trial. After general anesthesia, a unilateral QL block was performed under ultrasound guidance. Opioid consumption and numeric rating scale (NRS, 0–10) pain scores were recorded at 2, 6, 12, 24, 48, and 72 hours postoperatively. The primary outcome was the NRS pain score at rest at 6 hours. Secondary outcomes included pain scores, rescue analgesics over 72 hours, Quality of Recovery-15 scores in 24 hours, complications, and length of hospital stay.
Results
Baseline characteristics were similar among the 54 patients (27 per group) who completed the study, excluding three who dropped out. The QL block did not reduce NRS pain scores at rest at 6 hours (median [interquartile range], 5 [4–6] vs. 5 [3–6]; p=0.78). Over the 72-hour postoperative period, pain scores at rest remained comparable between the groups, while the QL group showed slightly lower movement-induced pain at certain time points. The QL group required fewer analgesics and antiemetics at certain intervals, but the total opioid use, length of hospital stay, and quality of recovery were not significantly different.
Conclusion
The QL block showed no meaningful advantage in postoperative analgesia compared to placebo for ileostomy closures.

Amid the worldwide increase in spinal surgery rates, a significant proportion of patients continue to experience refractory chronic pain, resulting in reduced quality of life and escalated healthcare demands. Failed back surgery syndrome (FBSS) is a clinical condition characterized by persistent or recurrent pain after one or more spinal surgeries. The diverse characteristics and stigmatizing descriptions of FBSS necessitate a reevaluation of its nomenclature to reflect its complexity more accurately. Accurate identification of the cause of FBSS is hampered by the complex nature of the syndrome and limitations of current diagnostic labels. Management requires a multidisciplinary approach that may include pharmacological treatment, physical therapy, psychological support, and interventional procedures, emphasizing realistic goal-setting and patient education. Further research is needed to increase our understanding, improve diagnostic accuracy, and develop more effective management strategies.

Abstract PDF

Breakthrough pain is transitory pain that occurs despite the use of opioids for background pain control. Breakthrough pain occurs in 40% to 80% of patients with cancer pain. Despite effective analgesic therapy, patients and their caregivers often feel that their pain is not sufficiently controlled. Therefore, an improved understanding of breakthrough pain and its management is essential for all physicians caring for patients with cancer. This article reviews the definition, clinical manifestations, accurate diagnostic strategies, and optimal treatment options for breakthrough pain in patients with cancer. This review focuses on the efficacy and safety of rapid-onset opioids, which are the primary rescue drugs for breakthrough pain.

Abstract PDF: Background
The first large coronavirus disease 2019 (COVID-19) outbreak outside China occurred in Daegu. In response, we developed infection prevention measures for surgical patients during the outbreak at our hospital and retrospectively reviewed the outcomes of COVID-19–related surgical patients.
Methods
We reviewed the medical records of 118 COVID-19–related surgical patients and monitored their clinical outcomes until March 31, 2021. We also interviewed healthcare workers who participated in their perioperative care at Kyungpook National University Chilgok Hospital. The perioperative management guidelines for COVID-19–related patients were prepared through multidisciplinary discussions, including the infection control department, surgical departments, and anesthesiology department before and during the COVID-19 outbreak.
Results
One standard operating room was temporarily converted to a negative-pressure room by increasing the exhaust air volume, creating a relative pressure of −11.3 Pa. The healthcare workers were equipped with personal protective equipment according to the patient's classification of the risk of COVID-19 transmission. The 118 COVID-19–related patients underwent emergent surgery in the negative-pressure room, including three COVID-19–confirmed patients and five COVID-19–exposed patients.
Conclusion
All surgeries of the COVID-19–related patients were performed without specific adverse events or perioperative COVID-19 transmission. Our experience setting up a negative-pressure operating room and conservative perioperative protocol to prevent COVID-19 transmission will help plan and execute infection control measures in the future.
