You have failed cannulation twice on a septic, agitated patient. What are your concerns and what do you do?

• A. Continue attempting cannulation until successful
• B. Get senior team members in the room to ensure patient remains stable/manage deteriorating patient
• C. De-escalate verbally and with non-threatening communication, then proceed
• D. If the patient becomes aggressive, call code grey/black

Answer: (B)

When a septic, agitated patient needs vascular access, safety and timely, reliable access take priority. After two failed cannulation attempts, continuing the chase with more attempts is unlikely to succeed quickly and increases risk of delays, vessel injury, hematoma, vasospasm, and deterioration of the patient’s condition. The best course is to bring in senior team members to reassess and guide the plan, ensuring the patient remains stable while you decide on the next access strategy. Experienced clinicians can quickly determine whether to switch to an alternative peripheral approach (for example ultrasound-guided cannulation at a new site) or move to an alternative method such as intraosseous access, and they can coordinate monitoring, fluids, and antibiotics so treatment isn’t delayed. While de-escalation and calm communication can help reduce agitation, they should accompany, not replace, the priority of stabilizing the patient and securing reliable access with experienced support. If aggression escalates and safety is at immediate risk, appropriate emergency response protocols are used, but the central idea remains: escalate to senior help to protect the patient and reestablish a safe, effective plan.
