SURGICAL IMPLANT SITE INSPECTION: Assessment of the subcutaneous port pocket and tunnel track for erythema, induration, swelling, tenderness, or signs of localized pocket infection and catheter migration.

SURGICAL ANTISEPTIC PREPARATION & DRAPING: Aseptic non-touch technique (ANTT) protocol involving chlorhexidine gluconate skin antisepsis with friction scrub, adequate drying, and sterile fenestrated drape placement.

NON-CORING HUBER NEEDLE ACCESS: Precision cannulation through the silicone septum using a safety-engineered, non-coring Huber needle (20G or 22G) to preserve septum integrity and ensure line access.

BLOOD RETURN CONFIRMATION & PULSATILE FLUSH: Aspiration to verify brisk, free-flowing venous blood return followed by turbulent, push-pause normal saline flushing to clear intraluminal fibrin debris.

HEPARIN LOCK & STERILE OCCLUSIVE DRESSING: Instillation of dilute heparinized saline solution under positive pressure to prevent line thrombosis, followed by sterile transparent dressing application with chlorhexidine-impregnated sponge patch.
