Abstract: This study tested the hypothesis that four ocular irrigating solutions were equally irritating during copious irrigation. We conducted a prospective, double-blind study of patients with chemical exposure to the eye. Each underwent cross-over irrigation with all of the following in random order: normal saline (NS), lactated Ringer’s (LR), normal saline adjusted to pH 7.4 with sodium bicarbonate (NS + Bicarb), and Balanced Saline Solution Plus (BSS Plus, Alcon Laboratories, Fort Worth, TX). Compared with traditional NS and LR, NS + Bicarb tended to be more comfortable. BSS Plus was statistically superior (P less than .05) to NS and preferred over LR and NS + Bicarb. Three patients demanded discontinuance of NS or NS + Bicarb infusions. All solutions had comparable normalization of conjunctival pH and degree of injection. Alternate solutions including BSS Plus should be considered for use in those patients whose poor tolerance to normal saline threatens to delay or interrupt eye irrigation following a chemical injury.
MorTan Note: This study, done on patients with actual chemical burns, involved 11 patients and 12 eyes.
I can testify to a positive experience with the Morgan Lens. Patient: myself. I had a patient who regurgitated the charcoal given to him for his OD, just after I had removed my protective face mask. I sustained an eyeful of activated charcoal. It was removed almost painlessly by several liters of N.S. irrigation via the Morgan Lens, much more easily than the "old way" of using fingers to open lids and squirting the eye.Physician (Virginia)
The Morgan Lens is used in 90% of hospital emergency departments in the USA and can be inserted in less than 20 seconds. There simply is no other "hands-free" method of eye irrigation. Nothing else frees medical personnel to treat other injuries or to transport the patient while irrigation is underway. Nothing is more effective at treating ocular chemical, thermal, and actinic burns or removing non-embedded foreign bodies, even when the patient's eyes are closed tightly. Its design makes it simple and straightforward to use so minimal training is required.
