How to Use a B. Braun Infusion Pump
Consult the manufacturer's specific instructions for your B. Braun pump model, ensure compatible administration sets are used with proper filter integration (170-200 μm), verify correct free-flow clamp installation to prevent gravity flow, and always perform pre-administration checks of device settings before initiating infusion. 1, 2
Critical Setup Requirements
Administration Set Compatibility and Safety
- Only use administration sets verified as compatible by B. Braun for your specific pump model 1
- The administration set must incorporate an integral mesh filter (170-200 μm) 1
- Critical safety check: Verify the free-flow clamp is correctly inserted in the pump mechanism, as incorrect installation can result in dangerous gravity flow and overinfusion 2
Pre-Administration Verification
Before starting any infusion, perform these mandatory checks:
- Verify device settings match the prescription 1
- Confirm the pump displays the correct infusion rate
- Check that all clamps are properly positioned
- Ensure alarm functions are active and audible 3
Operational Principles
Flow Control and Monitoring
Modern infusion pumps should have 3:
- Accurate flow control capability, particularly at low flow rates
- Free flow prevention if the pump door is opened during use
- Lockable settings to prevent tampering
- Active alarm functions with appropriate sensitivity
Monitor the volume delivered regularly throughout the infusion to ensure the expected volume is delivered at the required rate 1
Smart Pump Features
If using a B. Braun smart pump system 4:
- Utilize the drug library with guardrails and alerts
- Ensure barcode scanning is functional (if equipped)
- Verify audible and visual cues are working
- Confirm standardization across your unit
Special Considerations
Positioning for Microinfusions
When administering vasoactive drugs or other critical medications at low flow rates (e.g., 1 mL/h):
- Position the pump at the intended vertical height BEFORE purging and connecting to the central venous catheter 5
- This prevents significant anterograde or retrograde fluid shifts
- Positioning after connection can cause bolus events or prolonged lag times, particularly dangerous with vasoactive drugs 5, 6
Secondary Medication Administration
For secondary (piggyback) infusions 7, 8, 9:
- Understand your specific pump's head-height differential requirements (if applicable)
- Verify roller clamps are open before initiating secondary infusion
- Monitor for alarm alerts indicating setup issues
- Note that cassette-based systems may have different requirements than linear peristaltic systems
Maintenance and Safety Culture
Regular Maintenance
- Infusion devices must be regularly maintained per manufacturer specifications 1
- Report any adverse outcomes from pump use to appropriate regulatory agencies (e.g., MHRA in UK, FDA in US) 1
Common Pitfalls to Avoid
- Never assume all B. Braun pumps operate identically - different models have different requirements 2, 10
- Incorrect free-flow clamp installation is a known hazard with the Infusomat Space model 2
- Positioning errors with microinfusions can cause hemodynamic instability 5, 6
- Failure to verify settings before starting infusion is a frequent source of medication errors 4
Documentation and Handoffs
During shift changes or patient transfers 4:
- Review all drugs currently infusing
- Verify pump settings with incoming staff
- Document any programming changes
- Perform "clean sweep" of all syringes and containers at case end
Device-Specific Certification
Ensure you receive formal training on your institution's specific B. Braun pump model before independent use, as features and safety mechanisms vary significantly between models (e.g., Outlook 100, Outlook 200, Infusomat Space) 2, 10. The Outlook 200's automated bar-code programming system, while innovative, requires successful implementation protocols specific to your clinical setting 10.
