At our hospital IV IG is not filtered. It must be infused through a line with D5W. The IVIG dose is determined by the MD but we calculate the rate of the infusion. Vital signs are obtained pre-infusion. After the infusion is started, vitals are obtained every 15 minutes. If after the 15 minute increment if the vitals are stable then the infusion is titrated up for another 15 minutes. After the 2nd 15 mins vitals are obtained and if vitals are stable the infusion is again titrated aand this continues for 2 more cycles of 15 mins. The remaining drip is infused at the rate of the 4th increment and vitals are obtained 30mins and 1 hour after the infusion is completed. If the patient is going to experience an adverse reaction it usually occurs during the titration.
