If you are unsure about the severity of a chemical ocular injury, proceed with irrigation of the eye. Check the pH of the eye(s) when irrigation is finished. This procedure should be undertaken only after approved training, supervised practice and competency assessment, and carried out in accordance with local policies and protocols. The link you have selected will take you to a third-party website. After irrigation is complete, evert the upper eyelid, to ensure that there are no residual deposits in the superior conjunctiva. Procedure: 1. Ask the patient to look downwards, and insert the lens under the upper lid. Chemical injury to the eye (caustic chemical burns are a medical emergency; irrigation should begin as soon as possible, with on-site flushing with whatever water is available, even before medical help arrives), Removal of small particulate matter from the eye, Treatment of foreign body sensation when no particulates are visible (sometimes successful). Normal pH of the eye as measured with pH paper is about 7.0. 31. Pour a small amount of irrigation fluid from the undine or infusion set across the patient’s cheek. In many cases, 15 to 20 min of irrigation are required and several liters of irrigant are often used. Irrigate the eye manually, gently, and very carefully.

Ensure the patient’s privacy by screening the bed or ensuring their room door is closed. Sweep both the inferior and superior fornices. , MD, Wilmer Eye Institute, Retina Division, Johns Hopkins University School of Medicine. Some units also use a Morgan Lens – this resembles a contact lens connected to tubing; it sits over the eye and can be attached to an intravenous infusion set (Dougherty and Lister, 2015). If only one eye is affected by contamination, it is important to check the pH in both eyes as the pH of the unaffected eye can be used as a control to evaluate treatment. This interval ensures that the irrigation fluid has been cleared from the eyes and the pH of the tears is being assessed rather than that of the irrigation fluid. Tell the patient that irrigation is going to start. This should include the amount of irrigation fluid used, the length of the irrigation and the pH readings. Sign in or Register a new account to join the discussion. After the procedure, the patient’s vision must be assessed and any relevant history recorded. If the cornea may have a deep injury or foreign body, irrigation using a scleral lens may cause further injury and should not be done. If particulate material may be in the eye and significant chemical exposure is unlikely, sweep potential particulate matter out with a moistened cotton-tipped applicator before irrigation. A supported position will help minimise discomfort during the procedure (Dougherty and Lister, 2015). tip of the irrigation syringe/bottle should not touch any part of the eye.

Ask the patient to turn their head towards the affected side and place a kidney dish next to their cheek (Fig 5). Patient position: a. Place the patient supine on the bed or stretcher. If the cornea may have a deep injury or foreign body, irrigation using a scleral lens may cause further injury and should not be done. To insert the device, ask the patient to look down as you insert the lens under the upper eyelid. Retract the eyelids to adequately irrigate the fornices. If the pH of the eye is outside the normal range, irrigation should be recommenced and continue until a normal pH of 7.0-7.4 is achieved (Corbett and Bizrah, 2018). Eye irritation is a common complaint. The legacy of this great resource continues as the Merck Manual in the US and Canada and the MSD Manual outside of North America. Nursing Times [online]; 116: 2, 46-48. Then, manually lift the upper lid margin, folding it backward over the applicator (ie, upward and backward toward the patient’s forehead). I have been told several things but would appreciate any and all suggustions Thank you Tj . If eye perforation is suspected, irrigation should be deferred until formal eye examination can be done.
