Electrical impedance tomography confirmed the impact of the method of delivery of term neonates on early lung aeration.
Background: The number of infants born via cesarean section (CS) is increasing globally due to medical and cultural reasons.
Objectives: This study aimed to determine the effect of the mode of delivery on early lung aeration in newborns using electrical impedance tomography (EIT).
Material and methods: The case-control study was conducted from December 2020 to April 2021. It included 32 term neonates delivered by CS and 20 term neonates delivered by normal vaginal delivery (NVD) as controls. Electrical impedance tomography examinations were performed with a Swisstom BB2 device with NEO SensorBelt and 32 integrated electrodes at 47.68 Hz. Three data recordings were conducted within 30, 60 and 90 min (mean times: 13, 62 and 93 min, respectively) after the birth.
Results: Cesarean section neonates, compared to those delivered by NVD, had greater non-aerated areas in gravity-dependent lung regions at the 2nd recording (p = 0.04). The CS group showed lower changes in lung stretch at the 2nd and 3rd recording compared to the NVD group (p = 0.022 and p = 0.032, respectively). In the study group, lung regions with the lowest stretch (10-20%, 20-30% and 30-40%) corresponded with increased total lung capacities 1 h after birth compared to the control group (p = 0.024, p = 0.004 and p = 0.044, respectively). Measurements from the 1st and 3rd EIT recording showed a greater distribution of tidal volume (TV) in the right lung toward the central regions among CS neonates compared to NVD neonates, whereas NVD neonates showed increased distribution of TV toward the central-ventral regions of the right lung immediately after birth.
Conclusions: The mode of delivery significantly affects early postnatal lung aeration in term neonates assessed using EIT. Caesarean section neonates were characterized by poorer aeration in gravity-dependent lung regions, whereas NVD neonates demonstrated greater changes in lung stretch and more intense tissue expansion, potentially leading to better postnatal adaptation.
期刊介绍：
Advances in Clinical and Experimental Medicine has been published by the Wroclaw Medical University since 1992. Establishing the medical journal was the idea of Prof. Bogumił Halawa, Chair of the Department of Cardiology, and was fully supported by the Rector of Wroclaw Medical University, Prof. Zbigniew Knapik. Prof. Halawa was also the first editor-in-chief, between 1992-1997. The journal, then entitled "Postępy Medycyny Klinicznej i Doświadczalnej", appeared quarterly.
Prof. Leszek Paradowski was editor-in-chief from 1997-1999. In 1998 he initiated alterations in the profile and cover design of the journal which were accepted by the Editorial Board. The title was changed to Advances in Clinical and Experimental Medicine. Articles in English were welcomed. A number of outstanding representatives of medical science from Poland and abroad were invited to participate in the newly established International Editorial Staff.
Prof. Antonina Harłozińska-Szmyrka was editor-in-chief in years 2000-2005, in years 2006-2007 once again prof. Leszek Paradowski and prof. Maria Podolak-Dawidziak was editor-in-chief in years 2008-2016. Since 2017 the editor-in chief is prof. Maciej Bagłaj.
Since July 2005, original papers have been published only in English. Case reports are no longer accepted. The manuscripts are reviewed by two independent reviewers and a statistical reviewer, and English texts are proofread by a native speaker.
The journal has been indexed in several databases: Scopus, Ulrich’sTM International Periodicals Directory, Index Copernicus and since 2007 in Thomson Reuters databases: Science Citation Index Expanded i Journal Citation Reports/Science Edition.
In 2010 the journal obtained Impact Factor which is now 1.179 pts. Articles published in the journal are worth 15 points among Polish journals according to the Polish Committee for Scientific Research and 169.43 points according to the Index Copernicus.
Since November 7, 2012, Advances in Clinical and Experimental Medicine has been indexed and included in National Library of Medicine’s MEDLINE database. English abstracts printed in the journal are included and searchable using PubMed http://www.ncbi.nlm.nih.gov/pubmed.
