Es Enteral Nutrition Insulin Regimen

---
name: es-enteral-nutrition-insulin-regimen
description: Select either neutral protamine Hagedorn (NPH)-based or basal bolus insulin regimens for glycemic management in hospitalized patients receiving enteral nutrition with diabetes-specific or nonspecific formulations. Triggered when clinicians ask, "Patient on enteral nutrition, which insulin regimen should we use?" or encounter hyperglycemia during tube feeding.

# Use NPH-based or basal bolus insulin regimens for enteral nutrition-associated hyperglycemia

## STEP 1 — Gather Information
Collect enteral nutrition pattern (continuous, bolus, cyclic), recent point-of-care glucose values, history of hypoglycemia, current insulin regimen, renal function (eGFR), and nutritional goals.  
**Action:** Proceed to assess suitability for an NPH-based regimen.

## STEP 2 — Rule In / Rule Out
If enteral nutrition is continuous and predictable, and there is no history of severe hypoglycemia or renal insufficiency (eGFR <30 mL/min/1.73 m²), rule in an NPH‑based regimen; otherwise rule out NPH and proceed to a basal bolus insulin regimen.  
**Action:** Choose NPH‑based pathway or basal bolus pathway.

## STEP 3 — Classify or Stratify
For the NPH pathway: continuous feeds → NPH once daily at bedtime; cyclic/bolus feeds → NPH twice daily (morning and evening) with prandial correction.  
For the basal bolus pathway: basal insulin 0.1‑0.2 U/kg once or twice daily plus rapid‑acting insulin q4‑6h or before meals if eating.  
**Action:** Determine specific insulin dosing strategy.

## STEP 4 — Decide
Initiate the selected regimen: NPH‑based → administer NPH per schedule plus rapid‑acting correctional insulin q4‑6h (or before bolus feeds); basal bolus → administer basal insulin once or twice daily plus rapid‑acting insulin q4‑6h or before meals, adjusting to maintain glucose targets 100‑180 mg/dL.  
**Action:** Order insulin and set glucose monitoring schedule.

## Clinical Guardrails / Mimics / Pitfalls
Avoid NPH in patients with intermittent enteral feeding, high hypoglycemia risk, or eGFR <30 mL/min/1.73 m²; do not rely on sliding scale insulin alone; monitor glucose q4‑6h to prevent hypoglycemia; withhold prandial bolus if patient is NPO.

## Concrete Clinical Example
A 68‑year‑on continuous PEG tube feeds with diabetes‑specific formula, glucose 150‑220 mg/dL, no hypoglycemia, eGFR 55 mL/min. Choose NPH 0.2 U/kg at bedtime plus rapid‑acting insulin 4 units q6h; after 24 h, increase NPH to 0.25 U/kg based on pre‑feed glucose.
