Background: The placenta is the functional unit for the growth and survival of the fetus and is responsible for providing all the nutritional requirements to the fetus during the gestation period. Perinatal pathological processes occur due to alterations in placental function defined as placental insufficiency, so it is essential to identify anomalies in its structure and function. Objective: To determine if Doppler flowmetry of the middle cerebral artery is a good predictor of acute placental insufficiency in full-term fetuses with normal growth at the Adolfo Guevara Velasco-Cusco National Hospital, period 2022 -2023.Method: This is an observational, prospective, and cross-sectional study. In which 98 pregnant women from 37 to 42 6/7 weeks of gestation who complied with the rules to be included and did not present any exclusion criteria were included. Results: It is estimated that the risk of presenting indicators of placental insufficiency in pregnant women with a pathological middle cerebral artery pulsatility index was for: NST<8 (RR=6.2, CI 3.47 to 11.02), CST<8 (RR=3.7 ), CI 1.67 to 7.96), APGAR <7 at 5 minutes (RR=4.6, CI 2.49 to 8.3), category III in intrapartum monitoring (RR=2.6, CI 1.82 to 3.59), emergency cesarean section for SFA (RR = 2.1, CI 1.04 to 4.04); In addition, the sensitivity and specificity for each indicator was found, with greater sensitivity and specificity (S:86%, E:97%) as a diagnostic test for abnormal aortic isthmus. Conclusions: The usefulness of Doppler flowmetry of the middle cerebral artery as a predictor of acute placental insufficiency in pregnant women with term and post-term fetuses with adequate growth was demonstrated. Good sensitivity and specificity were found for indicators of non-severe acute fetal distress. The alteration of Doppler flowmetry of the middle cerebral artery in term and post-term fetuses is a good predictor of acute placental insufficiency and should therefore be taken into account for the early control of pregnant women with term or post-term fetuses of adequate growth before of adverse outcomes occurring.
