When vomiting occurs in a lively baby, mothers and fathers are anxious. In fact, vomiting is one of the most common symptoms in children, as early as in the famous playwright Shakespeare’s work “As You Like It”, there is “bent in the mother’s arms vomiting babies,” the description. Vomiting is common in children because of its physiological and anatomical characteristics, the baby was born with a transverse stomach, easy to fold, coupled with the sphincter is not developed, it is easy to vomit, this vomiting is mostly a physiological phenomenon, about 60% in the postnatal age of 1 to 1.5 years disappeared, 30% lasted until about 4 years old relief, only about 10% is pathological, requiring treatment. Vomiting is also a barometer reflecting the gastrointestinal function of the child, in order to ensure the healthy growth of the baby, parents should understand the characteristics of some common pediatric vomiting and principles of treatment. First, pay attention to the color of the vomit. The contents of physiological vomiting are mainly milk and milk lumps, commonly known as “milk spillage”. It is characterized by the occurrence of more in the milk, especially when lying down, after changing to the holding position, vomiting significantly reduced. This vomiting will gradually ease as the baby develops and adds complementary foods. In this case, do not feed too fast and too much milk, feeding to take a half-slope position or the corner of the bed padded high, after feeding the baby will pick up after patting the back, so that the little one a burp, which can reduce the occurrence of vomiting. Later, with the addition of the right amount of complementary food, increase the consistency of milk, vomiting can gradually disappear. If the baby is vomiting yellow-green watery material, which is the color of bile, so called bilious vomiting, indicating that there is an obstruction of the intestinal canal, caused by reflux of intestinal contents, is a danger signal of intestinal obstruction, this can not be taken lightly, to send the baby to the hospital for examination and treatment as soon as possible. If the home is remote and it is difficult to reach the hospital for a while, do not feed the baby food or water during transportation to avoid aggravating the intestinal obstruction. If the vomit is red or coffee-colored, it indicates bleeding in the gastrointestinal tract. Bloody vomit is one of the pediatric emergencies, and sometimes shock can occur, which must be treated promptly. Secondly, pay attention to the way of vomiting and the accompanying symptoms. The baby vomits effortlessly after feeding, and the vomit overflows from the corners of the mouth, which is mostly a manifestation of physiological gastroesophageal reflux, and the child still has a strong appetite for food after vomiting, and the nutrition and development will not be affected by vomiting. If vomiting is jet-like, vomit is powerfully splashed to the bed or even the floor, suggesting that the distal end of the stomach (pylorus) obstruction, such as congenital hypertrophic pyloric stenosis, vomiting can be seen before the epigastric bulge, there is a peristaltic wave from left to right, encounter such cases, parents should be sent to the hospital for examination, surgical treatment is effective, delayed treatment can lead to malnutrition and even death by failure. If the vomiting is accompanied by fever, not to eat milk, cry sharp and straight, this is often a manifestation of intracranial infection, need to go to the hospital immediately, otherwise it will be life-threatening. In addition, parents should pay attention to the timing of vomiting and the relationship between vomiting and defecation. Most of the “milk spills” occur after the start of breastfeeding, and vomiting gradually decreases after a month, and the child’s stools are normal. If frequent vomiting occurs on the first day after birth, most of them are due to congenital gastrointestinal anomalies, such as intestinal atresia and anal atresia, etc. At this time, children often do not have fetal stool discharge, and surgery is the only treatment method. Pediatric vomiting with diarrhea, mostly due to inflammation of the gastrointestinal tract, indicating that vomiting is also a defense function of the body, the toxins in the intestinal tract can be expelled as soon as possible to reduce systemic toxic reactions. Therefore, the baby’s diet hygiene is also an important element that parents should not ignore, especially in the summer, the disinfection of tableware hygiene is an important condition to ensure the healthy growth of the baby. The most common complication of pediatric vomiting is aspiration, which is the return of vomit into the trachea, causing asphyxia or even sudden death. Parents of children vomiting emergency treatment is, do not panic, first of all, the child’s mouth vomit quickly remove clean, such as mis-aspiration has occurred, to take mouth-to-mouth to suck out the vomit, while the child will be repositioned or head high position to prevent vomiting again. At the same time, stop feeding milk and water, and observe the nature of vomiting and the presence of the above symptoms to take appropriate measures. In summary, vomiting is a barometer of pediatric gastrointestinal function. Through careful observation and scientific analysis, we can understand the status of pediatric gastrointestinal function in time, discover problems and treat them early so that your baby can develop normally and grow up healthily.
