Lung transplantation (LTx) aims at improving survival and quality of life for patients with end-stage lung diseases. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is used as intraoperative support for LTx, despite no precise guidelines for its initiation. We aim to evaluate two strategies of VA-ECMO initiation in the perioperative period in patients with obstructive or restrictive lung disease requiring bilateral LTx. In the control ‘on-demand’ arm, high haemodynamic and respiratory needs will dictate VA-ECMO initiation; in the experimental ‘systematic’ arm, VA-ECMO will be pre-emptively initiated. We hypothesise a ‘systematic’ strategy will increase the number of ventilatory-free days at day 28.

We designed a multicentre randomised controlled trial in parallel groups. Adult patients with obstructive or restrictive lung disease requiring bilateral LTx, without a formal indication for pre-emptive VA-ECMO before LTx, will be included. Patients with preoperative pulmonary hypertension with haemodynamic collapse, ECMO as a bridge to transplantation, severe hypoxaemia or hypercarbia will be secondarily excluded. In the systematic group, VA-ECMO will be systematically implanted before the first pulmonary artery cross-clamp. In the on-demand group, VA-ECMO will be implanted intraoperatively if haemodynamic or respiratory indices meet preplanned criteria. Non-inclusion, secondary exclusion and VA-ECMO initiation criteria were validated by a Delphi process among investigators. Postoperative weaning of ECMO and mechanical ventilation will be managed according to best practice guidelines. The number of ventilator-free days at 28 days (primary endpoint) will be compared between the two groups in the intention-to-treat population. Secondary endpoints encompass organ failure occurrence, day 28, day 90 and year 1 vital status, and adverse events.

Culture is highlighted in previous research as important in encounters where health professionals and children do not share a language or culture. In these encounters, culture is described as mainly related to the child, whereas the health professionals’ understanding of their own culture as impacting the encounter tends to be left out. To clarify how culture is understood and conceptualised among professionals, it is of relevance to collate previous research on health professionals’ understanding of culture. In the scoping review that this protocol describes, we aim to focus on the context of the school health services, being a context accessible to many children in their everyday life. The aim of the review will be to identify, describe and analyse previous research concerning school health professionals’ (ie, school nurses, school social workers, school doctors and school psychologists) understanding of culture.

This scoping review will be guided by the methodology described by Peters et al and Khalil et al. Searches will be conducted in Scopus, PubMed, Cinahl Plus, SocIndex, Sociological Abstracts, Social Services Abstracts, APA PsycInfo, APA PsycArticles, Web of Science and Applied Social Sciences Index & Abstracts (ASSIA). Any published scientific papers focusing on school health professionals’ understanding of culture (conceptualised through a variety of related terms) and school health services conducted within the last 10 years (2013–2023) will be included. Two reviewers will independently screen all titles and abstracts for inclusion. Two reviewers will conduct the screening of full-text documents and the extraction of information. Qualitative content analysis as well as discourse analysis will be employed.

Ethical approval is not required for this study. The findings will be disseminated through peer review publication as well as presentation at conferences and to relevant stakeholders.
