Achtergrond • Dierstudies: • Intra-arrest TH 1-4: • betere kans op ROSC & survival • betere neurologische uitkomst • Veilig, uitvoerbaar 5-7 • Effect mensen?

Conclusie studies • IATH middels infusie/transnasaal • Veilig en haalbaar • Trend naar meer ROSC, • Wschl. ook meer survival en betere neurologie • M.n. bij snelle start CPR en snelle start IATH
Discussie • Beperkte humane studies • Abstracts veelbelovend, grote aantallen, nog niet uitgewerkt • Meer ROSC bij IATH • Relatie ROSC-survival-neurologie nog niet bewezen • Meer RCT’s nodig met primaire doel survival/ neurologie
THM • O.b.v. eerder onderzoek: • geen adverse events, IATH haalbaar, neiging naar meer ROSC • Positief effect • Echter: veilig en haalbaar, dus… • Keep it cool & fast!
