A&A practice
-
A 63-year-old man with stage 3a chronic kidney disease (CKD) and mild hyperkalemia was scheduled for a robot-assisted prostatectomy. He was being treated with lisinopril. ⋯ Three hours after incision, electrocardiographic signs of hyperkalemia manifested with the serum potassium concentration rising to 8 mmol/L. Although hyperkalemia is a common and well-documented side effect of angiotensin-converting enzyme inhibitors in patients with CKD, we report an extreme increase in potassium within a very short time period despite prior drug discontinuation.

Case Reports
Local Anesthetic Systemic Toxicity in Cardiac Surgery Patient with Erector Spinae Plane Catheter: A Case Report.
Regional anesthesia nerve blocks are increasingly used for patients undergoing cardiac surgery as part of multimodal pain management. Though rare, local anesthetic systemic toxicity (LAST) is a severe complication that requires vigilant monitoring. ⋯ This episode was determined to be a result of impaired lidocaine metabolism from liver shock caused by worsening pulmonary hypertension. Even under continuous monitoring, patients with cardiac or liver dysfunction are at increased risk of complications from local anesthetics.

Case Reports
Ultrasound-Assisted Spinal Anesthesia in a Patient with a Preexisting Lumbar Interspinous Spacer: A Case Report.
An interspinous spacer is a minimally invasive implantable device for the treatment of lumbar spinal stenosis. The in situ implant may prevent safe and successful spinal anesthesia because its position can obstruct the path of the spinal needle. ⋯ Currently, there are no reported cases of ultrasound-assisted spinal anesthesia in patients with interspinous spacers. We present a case in which ultrasonography assisted the successful administration of a spinal anesthetic by avoiding an indwelling lumbar interspinous spacer.

Traditionally, intrathecal therapy has been used for pain amelioration in cancer patients, but now has indications for nonmalignant chronic pain conditions. Due to its expanding use, it is imperative to understand the risks and management of intrathecal pump implantation. This case illustrates a series of uncommon intrathecal pump complications in a 52-year-old woman with complex regional pain syndrome. Considering the complications outlined in this case, there is a need to conduct retrospective studies and establish guidelines to address when it is optimal to remove a chronically placed catheter as well as the proper technique for removal.

Ultrasound-guided percutaneous cryoneurolysis of the intercostal nerves is an effective analgesic modality for the management of postmastectomy pain syndrome. The duration of analgesia provided by intercostal cryoneurolysis for chronic postmastectomy pain syndrome may vary. ⋯ In this case report, we describe the repeated use of ultrasound-guided cryoneurolysis of the intercostal nerves to manage chronic postmastectomy pain for 2.5 years. No adverse events or long-term neurologic sequelae were reported.
