Can the baby that just born wash lacrimal passage

summary

For newborn babies, they are born with crying. For babies, in addition to being cute, they are especially fond of crying. Crying makes parents feel distressed and anxious, because it may cause eye inflammation. Let's talk about whether newborn babies can wash their lacrimal passages.

Can the baby that just born wash lacrimal passage

First, lacrimal passage includes lacrimal point, lacrimal canaliculus, lacrimal sac and nasolacrimal duct. The lacrimal point is located on the papillary eminence of the inner canthus of the palpebral margin. The position of the upper lacrimal point is slightly inward than that of the lower lacrimal point. Epiphora is often caused by the displacement of lacrimal point. Lacrimal canaliculi are the canaliculi between lacrimal point and lacrimal sac, which are divided into upper and lower canaliculi. The lateral part of each lacrimal canaliculus first forms a vertical direction with the palpebral margin, and then turns inward nearly at a right angle. The two lacrimal canaliculi converge into the common lacrimal duct, and then opens at the upper part of the lacrimal sac.

Second, the lacrimal sac is a membranous sac located in the anterior and inferior lacrimal fossa of the medial orbital wall. The upper end of the lacrimal sac closed into a blind end, about 3 ~ 5mm above the inner canthus. The lower end of the nasolacrimal duct. The length of lacrimal sac is about 1.2cm and the width is 0.4 ~ 0.7cm. The muscle fibers of orbicularis oculi muscle wrap around the lacrimal sac and canaliculus, which can contract and expand the lacrimal sac and promote the discharge of tears. The nasolacrimal duct is a membranous tube connecting the lower end of the dacryocyst. The upper part is embedded in the bony lumen, and the lower part gradually narrows into the mucosa of the lateral wall of the nose, opening in the lateral wall of the inferior meatus.

Third: insert the needle into the lacrimal point vertically, about 1.5 ~ 2.0 mm deep, and then turn it 90 degrees. Make the tip of the needle face to the nasal side, that is, the long end of the needle is parallel to the dangerous edge. The tip of the needle moves slowly along the lacrimal canaliculus. If there is no resistance, it can advance 5 ~ 6 mm. Push the liquid into the pipe evenly and properly. When flushing, if the resistance is large, there is countercurrent or outflow from another lacrimal canaliculus, it means that the lacrimal passage is blocked. Different parts of the lacrimal passage block the direction of the countercurrent fluid is also different. Pay attention to the depth of the needle so as not to damage the mucosa.

matters needing attention

For a newborn baby, it's better not to do lacrimal passage flushing for the child, but let the child slowly, wait until the child develops for a period of time, and then choose lacrimal passage flushing after the body has a certain bearing capacity and resistance, so that the disease can be treated more easily.
