CONTINUOUS IRRIGATION USING NASAL CANNULA

1. Instill topical anesthetic (0.5% proparacaine or 0.5% tetracaine) to traumatized eye(s).
2. Hang irrigation fluid (prefer normal saline or LRS) on IV pole inside pressure infusion bag and prepare to infuse by priming the fluid lines and connecting to the nasal cannula.
3. Position the nasal cannula on the MWD’s forehead so that the prongs provide continuous irrigation into both eyes. Run continuous irrigation with lines all the way open until a neutral pH point is achieved (pH 7.0 – 7.5). If not able to measure pH with pH paper or urine dipstick strips, irrigate with a minimum of 2 liters of fluid.
