# Managing IV Therapy

## Why This Skill Exists

Intravenous therapy is among the most common invasive procedures in healthcare, with over 90% of hospitalized patients receiving some form of IV therapy. The Infusion Nurses Society (INS) Standards of Practice (2021 edition) provide the evidence-based framework for vascular access device (VAD) selection, insertion, maintenance, and complication management. Infiltration and phlebitis are the most common IV complications, while catheter-related bloodstream infections (CRBSI) carry mortality rates of 12–25%. Joint Commission NPSG.07.04.01 (now consolidated under NPSG.07.06.01 for CLABSI) requires evidence-based practices for central line management. CMS considers CLABSI a Hospital-Acquired Condition with reimbursement implications. This skill ensures that nursing management of IV therapy follows INS standards for site assessment, maintenance, complication recognition, and documentation.

## Step 1 — Select Appropriate Vascular Access Device

Match device to therapy per INS recommendations:

1. **Short peripheral IV catheter (PIV)**:
   - Duration: < 6 days for most indications
   - Gauge selection: 22–24G for routine hydration/medication; 20G for blood transfusion, CT contrast; 18G for rapid fluid resuscitation, surgical cases
   - Preferred sites: forearm (most stable), hand; avoid antecubital fossa for non-emergent access (limits mobility, higher infiltration risk)
2. **Midline catheter**:
   - Duration: 1–4 weeks
   - Inserted in upper arm; tip terminates below the axilla, above the antecubital fossa
   - Suitable for: non-vesicant, non-irritant medications with pH 5–9 and osmolality < 900 mOsm/L
3. **Peripherally Inserted Central Catheter (PICC)**:
   - Duration: weeks to months
   - Tip terminates at the cavoatrial junction (confirmed by chest x-ray or intracavitary ECG)
   - Suitable for: vesicants, irritants, TPN, vasoactive medications, prolonged IV antibiotics
4. **Central Venous Catheter (CVC)**:
   - Non-tunneled: short-term ICU use (days to weeks)
   - Tunneled (Hickman, Broviac): long-term use (weeks to months)
   - Implanted port: intermittent long-term access (months to years)
5. **Intraosseous (IO)**: Emergency vascular access when IV access cannot be established within the clinical timeframe

## Step 2 — Assess IV Site Per INS Standards

Perform and document IV site assessment at the following intervals:
- **PIV**: At minimum every 4 hours for adults; every 1–2 hours for pediatrics, neonates, and critically ill; and with each medication administration
- **PICC/CVC**: Each shift and with each access/use

### Assessment Parameters

1. **Insertion site inspection**: redness, swelling, drainage, tenderness, warmth
2. **Dressing integrity**: clean, dry, intact, occlusive; transparent dressing allows continuous visualization
3. **Securement**: catheter stabilization device in place; no tension on tubing
4. **Phlebitis assessment** using INS Visual Infusion Phlebitis (VIP) Scale:
   - Grade 0: No symptoms
   - Grade 1: Slight pain near IV site or slight redness
   - Grade 2: Pain, redness, and/or swelling at IV site
   - Grade 3: Pain, redness, swelling, palpable venous cord
   - Grade 4: Pain, redness, swelling, palpable venous cord > 1 inch, purulent drainage
5. **Infiltration assessment** using INS Infiltration Scale:
   - Grade 0: No symptoms
   - Grade 1: Skin blanched, edema < 1 inch, cool to touch, with or without pain
   - Grade 2: Skin blanched, edema 1–6 inches, cool to touch, with or without pain
   - Grade 3: Skin blanched/translucent, gross edema > 6 inches, cool to touch, mild-moderate pain, possible decreased pulses
   - Grade 4: Skin blanched/translucent, tight, leaking, discolored, bruised, swollen, gross edema > 6 inches, deep pitting edema, circulatory impairment, moderate-severe pain; infiltration of blood product, vesicant, or irritant
6. **Patency**: flush easily without resistance; blood return present; no swelling during flush

---

## Step 3 — Maintain IV Site and Infusion System

1. **Dressing changes**:
   - Transparent semi-permeable dressing: change every 5–7 days (INS standard) or immediately if soiled, loosened, or damp
   - Gauze dressing: change every 2 days
   - Apply chlorhexidine-based skin antiseptic; allow to dry completely before applying new dressing
2. **Tubing changes** per INS standards:
   - Continuous infusions: change primary and secondary sets no more frequently than every 96 hours (unless contaminated or integrity compromised)
   - Intermittent infusions: change every 24 hours
   - Blood/blood products: change after each unit or every 4 hours
   - Lipid-containing solutions (TPN with lipids, propofol): change every 24 hours
3. **Flushing protocol**:
   - PIV: flush with preservative-free 0.9% sodium chloride before and after each use; minimum 3–5 mL
   - PICC/CVC: flush with 10 mL preservative-free 0.9% sodium chloride; lock per institutional protocol (heparin or saline)
   - Use pulsatile flush technique (push-pause) to clear the catheter lumen
4. **Needleless connector**: scrub with 70% isopropyl alcohol for ≥ 5–15 seconds (per institutional policy); allow to dry; change per manufacturer recommendation (typically every 96 hours or every 7 days with compatible IV sets)

## Step 4 — Monitor for and Manage IV Complications

### Infiltration/Extravasation
- **Stop** the infusion immediately
- **Aspirate** residual fluid from the catheter if possible
- **Remove** the PIV (do NOT remove if extravasation of a vesicant requiring antidote through the catheter)
- **Elevate** the affected extremity
- **Apply** warm or cold compresses per drug-specific protocol
- **Administer** antidote if vesicant extravasation (e.g., hyaluronidase for vinca alkaloid extravasation, phentolamine for vasopressor extravasation)
- **Notify** provider; document per institutional incident reporting

### Phlebitis (VIP Grade ≥ 2)
- **Remove** the PIV
- **Apply** warm compresses
- **Restart** in a different extremity if IV therapy must continue
- **Culture** the catheter tip if infectious phlebitis suspected
- **Document** VIP grade and interventions

### Catheter-Related Bloodstream Infection (CRBSI) Suspicion
- **Obtain** peripheral blood cultures (two sets from two sites) AND culture through the central line (if applicable) BEFORE starting antibiotics
- **Notify** provider immediately
- **Do not** remove the catheter until provider decision (some CVC infections can be treated with antibiotic lock therapy)
- **Document** signs/symptoms, cultures obtained, provider notification

### Air Embolism
- **Clamp** the catheter immediately
- **Position** patient in left lateral Trendelenburg (Durant's maneuver)
- **Administer** 100% oxygen
- **Call** rapid response/code
- **Document** event details, interventions, patient response

## Step 5 — Manage Smart Pump Infusions

1. **Program** the smart pump using the facility-specific drug library — do not use manual/basic mode for medications in the library
2. **Verify** all settings against the order: drug, concentration, dose, rate, volume to be infused
3. **Respond** to all alerts: soft alerts require clinical justification if overridden; hard stops cannot be overridden
4. **Document** any alert overrides with clinical rationale
5. **High-alert infusions** (vasopressors, insulin, heparin, sedation) require independent double-check by second RN
6. **Monitor** infusion site and patient response per drug-specific parameters

---

## Step 6 — Document IV Therapy Management

1. **New insertion**: date, time, inserter, device type, gauge, location, number of attempts, patient tolerance, blood return/flush verification, dressing applied
2. **Shift assessment**: site condition (VIP score, infiltration scale), dressing integrity, securement device status, device necessity review
3. **Maintenance activities**: dressing changes, tubing changes, cap/connector changes with date and time
4. **Infusions**: fluid/medication name, rate, volume, pump settings, patient response
5. **Complications**: description, grade (VIP or infiltration scale), interventions, provider notification, outcome
6. **Removal**: date, time, reason, catheter integrity (tip intact), site condition after removal, hemostasis achieved

## Guidelines

- **INS Standards of Practice (2021)**: The primary evidence-based reference for all vascular access and infusion therapy nursing practice
- **Joint Commission NPSG.07.06.01**: Evidence-based practices for prevention of CLABSI
- **CMS**: CLABSI is a Hospital-Acquired Condition; reimbursement implications for hospital-acquired CLABSI
- **CDC/HICPAC**: Guidelines for Prevention of Intravascular Catheter-Related Infections (2011, updated)
- **NDNQI**: Peripheral IV infiltration rates are a nursing-sensitive quality indicator
- **Device dwell time**: INS 2021 recommends clinically indicated removal rather than routine replacement for PIVs; assess for complications rather than replacing on a schedule
- **Scope of practice**: RN inserts PIVs, manages infusions, and assesses for complications; PICC insertion may be within RN scope with specialty training per state Nurse Practice Act; CVC insertion is a provider procedure; LPN/LVN IV therapy scope varies by state
- **Vesicant extravasation**: Classified as a sentinel event when resulting in significant harm; requires immediate intervention and incident reporting
- **Smart pump safety**: Drug library use reduces dosing errors; override rates should be monitored as a safety metric
