Overview
Pain on injection of rocuronium, particularly noted during precurarization, can be influenced by patient gender, with women experiencing higher incidence and severity compared to men 1.Diagnosis
Incidence Assessment: Evaluate pain perception using a numerical rating scale (NRS 0-10) post-injection 1.
Gender Consideration: Higher likelihood of pain in female patients compared to males 1.Management
Preemptive Measures: Consider local anesthetic infiltration at the injection site to mitigate pain 1.
Alternative Agents: Evaluate use of alternative muscle relaxants with lower injection pain profiles if pain is a significant concern 1.Special Populations
Gender Differences: Women report significantly more pain and higher severity compared to men during rocuronium injection 1.Key Recommendations
Monitor and document pain levels using a standardized scale (e.g., NRS) in both male and female patients post-rocuronium injection (Evidence: Moderate 1).
Consider gender-specific approaches to pain management, particularly offering additional analgesia or alternative relaxants to women (Evidence: Moderate 1).
Implement preemptive local anesthesia at the injection site to reduce the incidence and severity of injection pain (Evidence: Expert opinion 1).References
