The past decade has resulted in substantial progress in seizure detection and understanding the impact seizures have on the developing brain. Optical monitoring such as cerebral near-infrared spectroscopy (NIRS) and broadband NIRS can provide non-invasive continuous real-time monitoring of the changes in brain metabolism and haemodynamics. AIM: To perform a systematic review of optical biomarkers to identify changes in cerebral haemodynamics and metabolism during the pre-ictal, ictal, and post-ictal phases of neonatal seizures. METHOD: A systematic search was performed in eight databases. The search combined the three broad categories: (neonates) AND (NIRS) AND (seizures) using the stepwise approach following PRISMA guidance. RESULTS: Fifteen papers described the haemodynamic and/or metabolic changes observed with NIRS during neonatal seizures. No randomised controlled trials were identified during the search. Studies reported various changes occurring in the pre-ictal, ictal, and post-ictal phases of seizures. CONCLUSION: Clear changes in cerebral haemodynamics and metabolism were noted during the pre-ictal, ictal, and post-ictal phases of seizures in neonates. Further studies are necessary to determine whether NIRS-based methods can be used at the cot-side to provide clear pathophysiological data in real-time during neonatal seizures. date: 2022-08-02 date_type: published publisher: MDPI AG official_url: https://doi.org/10.3390/cells11162602 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1973487 doi: 10.3390/cells11162602 pii: cells11162602 lyricists_name: Tachtsidis, Ilias lyricists_name: Mitra, Subhabrata lyricists_id: ITACH19 lyricists_id: MITRA07 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner funding_acknowledgements: 219610/Z/19/Z [The Wellcome Trust]; MR/S003134/1 [Medical Research Council]; [National Institute for Health Research University College London Hospitals Biomedical Research Center] full_text_status: public publication: Cells volume: 11 number: 16 article_number: 2602 event_location: Switzerland citation: Howard, Rachel; Li, Runci; Harvey-Jones, Kelly; Verma, Vinita; Lange, Frédéric; Boylan, Geraldine; Tachtsidis, Ilias; Howard, Rachel; Li, Runci; Harvey-Jones, Kelly; Verma, Vinita; Lange, Frédéric; Boylan, Geraldine; Tachtsidis, Ilias; Mitra, Subhabrata; - view fewer <#> (2022) Optical Monitoring in Neonatal Seizures.
