Epicardial pacing wires are routinely used to avoid hemodynamic instability due to perioperative arrhythmias after cardiac surgery. In rare cases, pacing wires themselves can be associated with potentially life-threatening complications. Herein, we present a novel case of hemorrhagic shock and hemoperitoneum after temporary epicardial pacing wire removal.

Retained catheters are a rare but known complication of continuous peripheral nerve block. To date there have been several case reports of retained catheters but none that include longer-term follow-up of the patient experience and outcomes. ⋯ The patient initially experienced paresthesias emanating from the site of continuous peripheral nerve block catheter placement, but these issues resolved completely over several weeks. No infectious or serious sequelae were encountered during 6 months of follow-up.

We describe a patient's personal struggle with a symptom complex consisting of profound muscle weakness requiring pyridostigmine, and metabolic abnormalities suggestive of mitochondrial disease. This included a profound sensitivity to opioids, which in the past caused severe respiratory depression during a prior hospital admission. Interestingly, the patient herself is a professor of ethics in genomic sciences, and she and her medical team thus far have not been able to formally diagnose her with mitochondrial disease. The patient now presented for a multilevel lumbar spine fusion and her hospital course and perspective on her medical odyssey are described here.

Dying adolescents presenting for palliative procedures have complicated developmental and ethical issues, especially when reconsidering do-not-resuscitate orders. Though the American Academy of Pediatrics has guidelines, there is limited information in the literature on how to take care of these patients. ⋯ The patient's goals of treatment were elucidated through a comprehensive care team consisting of the procedural and oncology teams. Effective communication with the patient and family was paramount for success.

Peripheral nociceptors expressing the ion channel transient receptor potential cation channel, subfamily V, member 1, play an important role in mediating postoperative pain. Signaling from these nociceptors in the peri- and postoperative period can lead to plastic changes in the spinal cord and, when controlled, can yield analgesia. The transcriptomic changes in the dorsal spinal cord after surgery, and potential coupling to transient receptor potential cation channel, subfamily V, member 1-positive nociceptor signaling, remain poorly studied. ⋯ A single subcutaneous injection of resiniferatoxin before incision attenuated both evoked and nonevoked measures of postoperative pain. Surgical incision induced transcriptomic changes in the dorsal horn that persisted despite analgesia with resiniferatoxin, suggesting that postsurgical pain signals can be blocked without preventing transcription changes in the dorsal horn.
