Root Cause

Insulin pump infusion sets must be changed every 2-3 days (per manufacturer and ADA guidelines) to prevent lipodystrophy (hypertrophy or atrophy) at the site, which causes unpredictable insulin absorption, hyperglycemia, and DKA risk; extending to 7 days dramatically increases these complications.

胰岛素泵输注装置必须每2-3天更换一次（根据制造商和ADA指南），以防止注射部位脂肪营养不良（肥大或萎缩），这会导致胰岛素吸收不可预测、高血糖和DKA风险；延长至7天会显著增加这些并发症。

Workarounds

  1. 94% success Follow the '3-2-1 rule': change infusion set every 3 days (72 hours maximum), rotate site to a different body quadrant each time, and ensure at least 2 cm distance from previous site. Use a site rotation log (paper or app like 'Pump Site Tracker'). Set a calendar reminder for 3-day intervals.

  2. 65% success If supplies are limited, extend to 4 days maximum ONLY if using a steel cannula (e.g., Medtronic Sure-T) and monitoring blood glucose every 2 hours. Check site for redness, swelling, or pain. If glucose rises >50 mg/dL above baseline, change immediately.

  3. 88% success Use a 'site assessment' protocol before each insulin bolus: inspect site for signs of lipodystrophy (hard lump, dimpling, or discoloration). Palpate for induration. If any abnormality found, change to a new site in a different region. Document site condition in pump log.

Dead Ends

Common approaches that don't work:

  1. Rotate within the same general area (e.g., abdomen) every 7 days to minimize scar tissue 80% fail

    Rotating within the same area still allows lipodystrophy to develop; sites should be at least 2 cm apart and in different body regions (abdomen, thigh, arm, hip) in rotation.

  2. Use a longer cannula (e.g., 9mm instead of 6mm) to bypass surface lipodystrophy 75% fail

    Longer cannula may reach deeper tissue but does not prevent subcutaneous lipodystrophy at the insertion point; absorption remains erratic.

  3. Clean site with alcohol daily to prevent infection, allowing extended wear 70% fail

    Daily cleaning does not prevent lipodystrophy or absorption failure; infection risk is secondary to tissue damage from prolonged cannula presence.
