Posicionamento de Eletrodos de DEA com Porta de Quimioterapia: Evitando o Dispositivo

An implanted venous port (chemo port) requires modified AED pad placement to avoid interference and device damage.

Standard Placement (Anterolateral)

• Right pad: Right infraclavicular (just below clavicle, mid-clavicular line).
• Left pad: Left lateral chest (mid-axillary line, 5th intercostal space).

With Left-Sided Port (Typical)

• Right pad: Standard right infraclavicular.
• Left pad: **Anterior axillary line, 5th ICS** (lateral to port) OR **posterior left scapular** (if anterior not feasible).
• **Never place pad directly over port** (risk: device damage, current shunting, ineffective shock).

With Right-Sided Port

Mirror: Left pad standard; right pad moved laterally/posteriorly.

Key Principles

• Current vector must traverse heart (ventricles).
• Port is metal + silicone; high impedance → current diversion.
• If uncertain, use anterior-posterior (AP) placement: sternum + left scapula — avoids most ports.

Post-Shock

Check port function (flush/aspirate) if pads near device; report to oncology team.

BLS/ACLS training should include port scenario practice.
