Montevideo units are a method of measuring uterine performance during labor. They were created in 1949 by two physicians, Roberto Caldeyro-Barcia and Hermogenes Alvarez, from Montevideo, Uruguay. They are exactly equal to 1 mmHg within 10 minutes.
It is based on the observation that this measurement does not change much in children between 6 months and five years old, so comparison to a "normal" measurement is useful. Based on analysis of field results, MUAC < 125mm corresponds to Global Acute Malnutrition and MUAC < 115mm with or without Oedema corresponds to Severe Acute Malnutrition. [11]
Throughout pregnancy, the uterus experiences motor denervation, thus inhibiting spontaneous contractions. The remaining contractions are predominantly hormonally controlled. The decrease in the coordination of uterine smooth muscles cells reduces the effectiveness of contractions, causing the uterus to enter a state of uterine quiescence. [ 8 ]
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
A spontaneous vaginal delivery (SVD) occurs when a pregnant woman goes into labor without the use of drugs or techniques to induce labor and delivers their baby without forceps, vacuum extraction, or a cesarean section. [1] An induced vaginal delivery is a delivery involving labor induction, where drugs or manual techniques are used to initiate ...
The two primary methods are testing for the female pregnancy hormone (human chorionic gonadotropin (hCG)) in blood or urine using a pregnancy test kit, and scanning with ultrasonography. [1] Testing blood for hCG results in the earliest detection of pregnancy. [2] Almost all pregnant women will have a positive urine pregnancy test one week ...
Bishop score, also Bishop's score or cervix score, is a pre-labor scoring system to assist in predicting whether induction of labor will be required. [1] It has also been used to assess the likelihood of spontaneous preterm delivery. [2]
An article published in 2004 concluded that a Kleihauer-Betke (KB) test is necessary in all cases of maternal trauma, as clinical evaluation is not sensitive enough for determination of risk of pre-term labour. It accurately predicts the risk of preterm labor after maternal trauma whereas the article concluded that clinical assessment does not.
