Effective protocol for continuous pericapsular nerve group block in femur fracture patients undergoing hip surgery: two case reports: Younghoon Jung, Sangmin Choi, Siyoung Lee, Nara Kim, Eunsoo Kim; Received April 1, 2024 Accepted June 15, 2024 Published online July 24, 2024; DOI: https://doi.org/10.7180/kmj.24.114 [Epub ahead of print]

Abstract PDF PubReader ePub: Pericapsular nerve group (PENG) block was introduced as an effective way to control postoperative pain in patients who have undergone hip surgery. Therefore, we would like to discuss how to perform PENG block accurately on the basis of two cases, both of which involved hip fracture patients. Ultrasound-guided continuous PENG block was performed, and postoperative pain was adequately controlled in both cases. To mount the catheter in the correct position, it should be inserted after the needle enters at the lowest angle possible. If it is confirmed that the psoas tendon is pushed upward without an increase in injection pressure during drug injection, an accurate continuous PENG block has been achieved. We also analyzed fluoroscopic images to determine how the drug spread, and we observed that the drug spread around the hip capsule along the iliacus and psoas muscle.

Development of severe junctional bradycardia after dexmedetomidine infusion in a polypharmacy patient: a case report and literature review: Soeun Jeon, Eunsoo Kim, Sun Hack Lee, Sung In Paek, Hyun-Su Ri, Dowon Lee; Kosin Med J. 2023;38(1):50-55.

Abstract PDF PubReader ePub: The authors report a case of newly manifested severe junctional bradycardia following dexmedetomidine administration during spinal anesthesia in a polypharmacy patient. A 77-year-old woman receiving multiple medications, including a beta-blocker and a calcium channel blocker, underwent right total knee arthroplasty. After spinal anesthesia, intravenous dexmedetomidine was initiated as a sedative; her heart rate decreased, followed by junctional bradycardia (heart rate, 37–41 beats/min). Dexmedetomidine was discontinued, and a dopamine infusion was initiated. Seven hours after surgery, junctional bradycardia persisted; a temporary transvenous pacemaker was inserted, and the beta-blocker and calcium channel blocker were discontinued. The patient was discharged on postoperative day 11 without any sequelae. Anesthesiologists should be aware of dexmedetomidine’s inhibitory effects on the cardiac conduction system, especially in geriatric patients taking medications with negative chronotropic effects and in combination with neuraxial anesthesia.
