Rocuronium is a neuromuscular blocking agent mainly used in anesthetic procedures. Two patients who died 53 and 76 days, respectively, after their last rocuronium exposure had low (0.002-0.007 mg/L) levels of the drug in femoral blood, urine and vitreous humor samples obtained at autopsy. In neither case, the cause of death was related to the exposure to rocuronium. Here, these two cases are presented and the implications of the findings discussed.

Upstream open reading frames (uORFs) are -regulatory motifs that are predicted to occur in the 5' UTRs of the majority of human protein-coding transcripts and are typically associated with translational repression of the downstream primary open reading frame (pORF). Interference with uORF activity provides a potential mechanism for targeted upregulation of the expression of specific transcripts. It was previously reported that steric block antisense oligonucleotides (ASOs) can bind to and mask uORF start codons to inhibit translation initiation, and thereby disrupt uORF-mediated gene regulation.

Article Synopsis
- Peripheral nerve blocks (PNBs) are commonly used in pediatric orthopedic surgery for pain management and quicker discharge, but they can lead to both short- and long-term complications.
- A systematic review identified 16 studies (10% of those reviewed) that discussed long-term complications following PNBs in pediatric patients, with 9 reporting issues such as chronic pain, motor deficits, and reduced range of motion.
- Overall, complications were noted in a small percentage of patients, with chronic pain occurring in 5%, strength deficits in 10%, and sensory deficits in just 0.07%.

Prescription-event monitoring (PEM) is the current gold standard for determining the risk of rare drug side-effects and comparing the risk between agents; however, spontaneous or prompted reporting schemes have low case-detection rates and exposure may be difficult to estimate. A novel method is described that allows a comparative adverse event rate between two drugs to be estimated-based on patterns of cross-reactivity-requiring only a sample of cases and no direct knowledge of drug exposure rates. Agreement was compared between the novel method and historical estimates of risk using PEM for comparative risk of rocuronium versus vecuronium anaphylaxis.

Background: Using neuromuscular blocking agents (NMBA) in pediatric induction protocol is a challenging matter. Therefore, in this study, we aimed to find a safer way for anesthesia in children. We compared the effects of dexmedetomidine with atracurium on intubation conditions in children aged 6-12 years under general anesthesia.

Article Synopsis
- Skeletal muscle relaxants are commonly used in anesthesia for surgeries, mechanical ventilation, and intubation, creating a conduction block at the neuromuscular junction.
- Reversal agents, like neostigmine and sugammadex, help terminate the neuromuscular blockade and prevent residual effects, but their efficacy can be affected by liver and kidney dysfunction.
- Liver damage, which can stem from various causes including drug toxicity and metabolic disorders, impairs drug metabolism and can lead to systemic complications, ultimately impacting the use of muscle relaxants in patients with liver disease.
