Vital Sign Monitoring During IVIG Infusion
Vital signs should be monitored during IVIG infusion because acute infusion reactions are often rate related. [1][2] Monitoring should include temperature, pulse (heart rate), respiratory rate, and blood pressure. [1][2] Oxygen saturation (SaO2) should also be documented per institutional infusion protocols. [2]
Vital Signs to Monitor
- Temperature. [1][2]
- Pulse (heart rate). [1][2]
- Respiratory rate. [1][2]
- Blood pressure. [1][2]
- Oxygen saturation (SaO2). [2]
Monitoring Frequency During Infusion
- Vital signs should be taken and documented prior to commencing the IVIG infusion. [1]
- Vital signs should be taken and documented prior to each rate increase. [1]
- Vital signs should be taken and documented hourly once the maximum infusion rate is achieved. [1]
- Vital signs should be taken and documented once the infusion is completed. [1]
- Patients should be observed for 20 minutes after completion of the infusion, with monitoring performed during this observation period. [1]
Monitoring Frequency During the Early Infusion Period (Protocol-Specific)
- Vital signs should be documented 15 minutes after commencing the infusion. [2]
- Close visual observation should be performed for at least 30 minutes after commencing the infusion. [2]
- Vital signs should be documented at each rate change. [2]
- Vital signs should be documented hourly until the infusion is completed. [2]
Rate-Change Triggers for Increased Monitoring
- Vital signs should be rechecked immediately prior to each rate increase. [1]
- Vital signs should be rechecked at each rate change in protocols that specify rate-change documentation. [2]
Post-Infusion Monitoring
- Monitoring should continue for 20 minutes after completion of the infusion for patients established on a particular IVIG product. [1]
- Patients who are naïve to IVIG, who are switching IVIG product, or who have had a long interval since prior IVIG should be monitored for a full hour after the infusion. [1]
Common Pitfall to Avoid
- Failure to intensify monitoring during early infusion, at rate changes, or during the post-infusion observation period increases the risk of delayed recognition of infusion-related reactions. [1][2]
