Comparison of terbutaline and atosiban as tocolytic agents in intrauterine repair of myelomeningocele: a retrospective cohort study. BRAZILIAN JOURNAL OF ANESTHESIOLOGY (ELSEVIER) 2024; 74:844495. [PMID: 38521500 PMCID: PMC10992278 DOI: 10.1016/j.bjane.2024.844495] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 02/25/2024] [Accepted: 03/04/2024] [Indexed: 03/25/2024]
Abstract
BACKGROUND Myelomeningocele (MMC) is a neural tube defect disease. Antenatal repair of fetal MMC is an alternative to postnatal repair. Many agents can be used as tocolytics during the in utero fetal repair such as β2-agonists and oxytocin receptor antagonists, with possible maternal and fetal repercussions. This study aims to compare maternal arterial blood gas analysis between terbutaline or atosiban, as tocolytic agents, during intrauterine MMC repair. METHODS Retrospective cohort study. Patients were divided into two groups depending on the main tocolytic agent used during intrauterine MMC repair: atosiban (16) or terbutaline (9). Maternal arterial blood gas samples were analyzed on three moments: post induction (baseline, before the start of tocolysis), before extubation, and two hours after the end of the surgery. RESULTS Twenty-five patients were included and assessed. Before extubation, the terbutaline group showed lower arterial pH (7.347 ± 0.05 vs. 7.396 ± 0.02 for atosiban, p = 0.006) and higher arterial lactate (28.33 ± 12.76 mg.dL-1 vs. 13.06 ± 6.35 mg.dL-1, for atosiban, p = 0.001) levels. CONCLUSIONS Patients who received terbutaline had more acidosis and higher levels of lactate, compared to those who received atosiban, during intrauterine fetal MMC repair.

Abstract
To support informed decisions on drug registration and prescription, clinical trials need tools to assess the efficacy and safety signals related to a given therapeutic intervention. Standardized assessment facilitates reproducibility of results. Furthermore, it enables weighted comparison between different interventions, instrumental to facilitate shared decisions. When focused on adverse events in clinical trials, tools are needed to assess seriousness, causality and severity. As part of such a toolbox, the international Neonatal Consortium (INC) developed a first version of the neonatal adverse event severity scale (NAESS). This version underwent subsequent validation in retro-and prospective trials to assess its applicability and impact on the inter-observer variability. Regulators, sponsors and academic researchers also reported on the use of the NAESS in regulatory documents, trial protocols and study reports. In this paper, we aim to report on the trajectory, current status and impact of the NAESS score, on how stakeholders within INC assess its relevance, and on perspectives to further develop this tool.

Risk factors for shunting at 12 months following open fetal repair of spina bifida by mini-hysterotomy. J Perinat Med 2023:jpm-2022-0212. [PMID: 36976874 DOI: 10.1515/jpm-2022-0212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Accepted: 02/22/2023] [Indexed: 03/30/2023]
Abstract
OBJECTIVES Open spina bifida (OSB) is the most common neural tube defect. Prenatal repair reduces the need for ventriculoperitoneal shunting (VPS) due to hydrocephalus from 80-90% to 40-50%. We aimed to determine which variables work as risk factors for VPS at 12 months of age in our population. METHODS Thirty-nine patients underwent prenatal repair of OSB by mini-hysterotomy. The main outcome was occurrence of VPS in the first 12 months of life. Logistic regression was used to estimate the odds ratios (OR) between prenatal variables and the need for shunting. RESULTS VPS at 12 months occurred in 34.2% of the children. Larger ventricle size before surgery (62.5% ≥15 mm; 46.2% between 12 and 15 mm; 11.8% <12 mm; p=0.008), higher lesion level (80% >L2, vs. 17.9% ≤L3; p=0.002; OR, 18.4 [2.96-114.30]), and later gestational age at surgery (25.25 ± 1.18 vs. 24.37 ± 1.06 weeks; p=0.036; OR, 2.23 [1.05-4.74]) were related to increased need for shunting. In the multivariate analysis, larger ventricle size before surgery (≥15 mm vs. <12 mm; p=0.046; OR, 1.35 [1.01-1.82]) and higher lesion level (>L2 vs. ≤L3; p=0.004; OR, 39.52 [3.25-480.69]) were risk factors for shunting. CONCLUSIONS Larger ventricle size before surgery (≥15 mm) and higher lesion level (>L2) are independent risk factors for VPS at 12 months of age in fetuses undergoing prenatal repair of OSB by mini-hysterotomy in the studied population.

Are Cervical Length and Fibronectin Predictors of Preterm Birth after Fetal Spina Bifida Repair? A Single Center Cohort Study. J Clin Med 2022; 12:jcm12010123. [PMID: 36614924 PMCID: PMC9821246 DOI: 10.3390/jcm12010123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 12/11/2022] [Accepted: 12/21/2022] [Indexed: 12/28/2022] Open
Abstract
Background: A remaining risk of fetal spina bifida (fSB) repair is preterm delivery. This study assessed the value of preoperative cervical length (CL), CL dynamics (∆CL) and fetal fibronectin (fFN) tests to predict obstetric complications and length of stay (LOS) around fSB repair. Methods: 134 patients were included in this study. All patients had CL measurement and fFN testing before fSB repair. ∆CL within the first 14 days after intervention and until discharge after fSB repair were compared in groups (∆CL ≥ 10 mm/<10 mm; ≥20 mm/<20 mm). CL before surgery, ∆CL’s, and positive fFN tests were correlated to obstetric complications and LOS. Results: Mean CL before surgery was 41 ± 7 mm. Mean GA at birth was 35.4 ± 2.2 weeks. In the group of ∆CL ≥ 10 mm within the first 14 days after intervention, LOS was significantly longer (p = 0.02). ∆CL ≥ 10 mm until discharge after fSB was associated with a significantly higher rate of GA at birth <34 weeks (p = 0.03). The 3 positive fFN tests before fSB repair showed no correlation with GA at birth. Conclusion: Perioperative ∆CL influences LOS after fetal surgery. ∆CL ≥ 10 mm until discharge after fSB repair has a 3-times higher rate of preterm delivery before 34 weeks. Preoperative fFN testing showed no predictive value for preterm birth after fSB repair and was stopped.
