Effects of prophylactic constant-rate infusion of norepinephrine or phenylephrine on neonatal outcomes during caesarean section.
Trial report in European journal of medical research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundProphylaxis of norepinephrine (NE) at a constant rate has been demonstrated to be as efficacious as prophylaxis of phenylephrine (PE) at equivalent doses for the prevention of maternal hypotension during cesarean section. Nevertheless, the impact of prophylactic infusion of NE or PE at a constant rate on pregnant women on fetal outcomes remains to be elucidated.
methods90 women scheduled for caesarean section under spinal or combined spinal-epidural anesthesia were randomly assigned to either the NE or PE group. The "study drug" (NE or PE) was administered intravenously at a rate of 15 mL/h from the time of injection of subarachnoid solution until the time of delivery of the fetus. Fetal umbilical artery (UA) blood was collected for blood gas analysis. The primary outcome of the study was base excess, and the incidence of fetal acidosis (Defined as base excess < 6 mmol/l) and blood glucose levels were also assessed.
resultsThe UA base excess mean (standard deviation) was not different from the NE group, - 1.6 (2.6) versus - 2.4 (2.9) in the PE group (P = 0.223). The incidence of fetal acidosis was 4.7% (NE) versus 14.3% (PE), with no statistically significant difference (P = 0.308). However, fetal blood glucose levels were significantly lower in the NE group, 3.16 (0.43) versus 3.43 (0.60) in the PE group (P = 0.019).
conclusionsProphylactic infusion of equivalent doses of NE at a constant rate resulted in fetal base excess values and an incidence of acidosis comparable to that of PE. However, a lower fetal UA blood glucose value was observed in the NE group, a finding that warrants further investigation.
