1 · What the graph read from it

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.

2 · The registry

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

backgroundVolatile anaesthetics have been suspected to increase intraoperative blood loss during caesarean section by causing uterine relaxation, but evidence from human studies remains inconclusive.

methodsWe conducted a retrospective observational study using a comprehensive perioperative dataset from the University of Tsukuba Hospital. We included 276 caesarean deliveries performed under general anaesthesia between April 2012 and March 2022, comparing patients who received volatile anaesthesia (n = 230) versus total intravenous anaesthesia (TIVA, n = 46). The primary outcome was intraoperative blood loss, and the secondary outcome was the administration of blood transfusion in the operating room. Multivariable regression models were used to adjust for differences in baseline characteristics.

resultsA total of 276 caesarean deliveries were included, with 230 patients in the volatile anaesthesia group and 46 in the TIVA group. The mean blood loss was 1,134.8 mL (SD 992.9 mL) in the volatile group and 1,097.8 mL (SD 764.1 mL) in the TIVA group. After adjustment for covariates, including emergency surgery and neoplasm, no significant difference in blood loss was observed (mean difference [volatile anaesthesia minus TIVA] 182 mL; 95% CI -123.5 to 487 mL; P = 0.244). Blood transfusion was performed in 8.3% of patients in the volatile group and 17.4% in the TIVA group, with no significant difference in the adjusted model (odds ratio 0.54; 95% CI 0.22 to 1.49; P = 0.211).

conclusionThis study found no significant association between the use of volatile anaesthesia and increased intraoperative blood loss or transfusion during caesarean section.
