Navigating Anesthesia: Muscle Relaxants and Reversal Agents in Patients with Renal Impairment.

This comprehensive review explores the interaction between neuromuscular blocking agents, reversal agents, and renal function, focusing on various drugs commonly used in anesthesia and their effects on kidney health. Succinylcholine, commonly used for anesthesia induction, can trigger elevated potassium levels in patients with specific medical conditions, leading to serious cardiac complications. While studies suggest the use of succinylcholine in patients with renal failure is safe, cases of postoperative hyperkalemia warrant further investigation. Some agents, such as atracurium and mivacurium, are minimally affected by impaired kidney function, whereas others, such as cisatracurium and rocuronium, can have altered clearance, necessitating dose adjustments in patients with renal failure. The reversal agents neostigmine and sugammadex affect renal markers, while cystatin C levels remain relatively stable with sugammadex use, indicating its milder impact on glomerular function, compared with neostigmine. Notably, the combination of rocuronium and sugammadex in rat studies shows potential nephrotoxic effects, cautioning against the simultaneous use of these agents. In conclusion, understanding the interplay between neuromuscular blocking agents and renal function is crucial for optimizing patient care during anesthesia. While some agents can be used safely in patients with renal failure, others can require careful dosing and monitoring. Further research is needed to comprehensively assess the long-term impact of these agents on kidney health, especially in high-risk patient populations. This article aims to review the use of muscle relaxants and reversal for anesthesia in patients with impaired renal function.

Erythema multiforme provoked by radiotherapy.

Radiation dermatitis is one of the most common adverse effects that occur in patients treated with radiation therapy. It is usually limited to the irradiated area. However, cases of generalized lesions have also been described in the literature. A rare but highly important cutaneous manifestation can be erythema multiforme-like lesions localized all over the patient's skin. A 63-year-old patient was admitted to the Department of Dermatology for disseminated erythematous lesions localized on the trunk and extremities. The patient denied taking any new medications or dietary supplements. However, he was undergoing radiotherapy treatment. On admission, the patient was in good general condition. During the stay in the department, the patient was treated orally as well as intravenously with corticosteroids, acyclovir, and a topical ointment consisting of gentamicin and betamethasone, as well as hydrocortisone and cooling ointment. After 1 month, a significant improvement in the patient's skin condition was noted. When skin lesions resembling erythema multiforme occur in patients undergoing oncological treatment, radiation therapy should be considered as a potential trigger.

Abscess after cardiac pacemaker implantation: A case report.

This is a report of one of the most serious complications of the cardiac pacemaker implantation - infection of the implanted system. We present the case, which was misdiagnosed at the beginning and after cardiological consultation it was decided to immediately remove the peacemaker and transfer the patient to the Cardiological Department.
