Pregnant mothers should pay attention to prevent bacteriuria

　　Bacteriuria refers to urine samples collected under aseptic techniques after cleaning the vulva, such as bacteria visible in every high-power field of the smear, or a culture colony count exceeding 100,000 per milliliter. This is the most common during pregnancy disease One, its incidence rate is 4% to 10%. Bacteriuria during pregnancy can cause more harm. right fetus For example, it can cause miscarriage, premature birth , and increase the risk of fetal death. Therefore, pregnant mothers should learn to prevent bacteriuria.

　　Some pregnant mothers will feel backache and fatigue in the third trimester of pregnancy, even accompanied by symptoms of chills, high fever, anorexia, nausea, and increased fetal movement. After examination, it was found that there were a large number of white blood cells in the urine of these pregnant women. Bacterial culture of clean mid-section urine revealed fungaluria. The symptoms were eliminated after a period of antibiotic treatment.

　　1. Causes of bacteriuria

　　Normally, urine is sterile, but the area around the urethral opening and the lower 1/3 of the urethra is bacterial. Therefore, urine discharged from the human body can be contaminated with some bacteria. However, the bacterial content of clean mid-section urine should not exceed 105/ml. If the bacterial count in two consecutive tests is greater than or equal to 105/ml, and they are of the same bacterial species, and there are no symptoms of urinary tract infection (frequent urination, urgency or lower abdominal discomfort, etc.), it can be diagnosed as true bacteriuria, also known as asymptomatic bacteriuria.

　　Bacteriuria during pregnancy is one of the most common diseases in women during pregnancy, with an incidence rate of 4% to 10%. The most common pathogenic bacteria of bacteriuria during pregnancy are Escherichia coli, accounting for more than 80%, followed by Proteus, Klebsiella, Aerobacter, Enterococcus, Streptococcus faecalis, and golden or white Grape cocci etc. These bacteria are already present in the urinary tract before pregnancy. In early pregnancy, due to increased secretion of progesterone, the tone of the renal pelvis, renal calyces, and ureters decreases. In late pregnancy, the enlarged Uterus Compression of the ureters (especially the right ureter) can cause obstruction and retention of urine, which is conducive to the growth of bacteria. In addition, the increase in nutrients in the urine of pregnant women is also conducive to the growth of bacteria. Bladder pressure and injury during childbirth, cesarean section Postpartum Difficulty urinating and the use of urinary catheters also increase the chance of upward bacterial infection. Therefore, the risk of bacteriuria is greatly increased during pregnancy. Some people have found that the older a pregnant woman is and the more pregnancies she has had, the greater the risk of bacteriuria.

　　2. Asymptomatic bacteriuria is also harmful

　　Bacteriuria during pregnancy can cause more harm. For the fetus, it can cause miscarriage, premature delivery, intrauterine growth retardation, respiratory distress syndrome, congenital malformations, etc., and increase the risk of fetal death. For pregnant women over 10 years old, bacteriuria may also be associated with gestational hypertension、anemia Wait related. Bacteriuria can cause acute pyelonephritis, which can lead to septic shock, acute renal insufficiency, or even renal failure. Once true bacteriuria is left untreated, 60% will develop into symptomatic infection and 30% will develop into pyelonephritis. Even after delivery, 30% of patients will still develop bacteriuria or urinary tract infection again, while the incidence of infection in women without bacteriuria during pregnancy is only 5%.

　　Bacteriuria during pregnancy is generally not easy to detect, and patients often seek medical treatment only when they develop systemic symptoms of acute pyelonephritis such as fever, chills, or even nausea and vomiting like Xiaoqing's. For this reason, experts recommend that pregnant women in early, middle, late pregnancy and prepartum should routinely conduct bacterial culture of clean mid-section urine to understand the presence of bacteriuria.
