In pulseless electrical activity occurring in the operating room, what is the immediate management?

• A. Start CPR immediately and call for help
• B. Administer vasopressin only
• C. Wait for audible heartbeat and monitor
• D. Increase anesthesia depth

Answer: (A)

In pulseless electrical activity, there is organized electrical activity on the monitor but no effective mechanical heartbeat and thus no pulse. The priority is to preserve perfusion and support the patient while you identify and treat reversible causes. Start high‑quality CPR immediately to maintain blood flow to the brain and vital organs, and simultaneously call for help and assemble the resuscitation team. In the operating room this means begin chest compressions right away, secure an airway, provide adequate oxygen, and monitor the rhythm as you address possible reversible factors such as hypoxia, hypovolemia, acidosis, electrolyte disturbances, tamponade, tension pneumothorax, toxins, or thrombosis. If the rhythm later becomes shockable or if signs evolve, follow ACLS steps accordingly (defibrillate if indicated, administer vasopressors, etc.). Quick commencement of CPR and team activation minimizes delays and improves chances of return of circulation.
