Abstract

Background

The assessment of intracranial pressure (ICP) is essential in the management of neurocritical care paediatric patients. The gold standard for invasive ICP is an intraventricular catheter or intraparenchymal microsensor but is invasive and carries some risks. Therefore, a non-invasive method for measuring ICP (nICP) would be desirable especially in the paediatric population. The aim of this study is to assess the relationship between ICP and different ultrasound–based methods in neurocritical care paediatric patients.

Methods

Children aged < 16 years with indication for invasive ICP monitoring were prospectively enrolled. The following non-invasive methods were compared with the invasive gold standard: optic nerve sheath diameter ultrasound (ONSD)–derived nICP (nICPONSD); arterial TCD–derived pulsatility index (PIa) and a method based on the diastolic component of the TCD cerebral blood flow velocity and mean arterial blood pressure (nICPFVd).

Results

We analysed 107 measurements from 10 paediatric patients. Results from linear regression demonstrated that, among the nICP methods, ONSD has the best correlation with ICP (r = 0.852 (p < 0.0001)). Results from receiving operator curve analysis demonstrated that using a threshold of 15 mmHg, ONSD has and area under the curve (AUC) of 0.94 (95% CI = 0.892–0.989), with best threshold at 3.85 mm (sensitivity = 0.811; specificity = 0.939).

Conclusions

Our preliminary results suggested that ONSD ultrasonography presents the best accuracy to assess ICP among the methods studied. Given its non-invasiveness, repeatability and safety, this technique has the potential of representing a valid option as non-invasive tool to assess the risk of intracranial hypertension in the paediatric population.

Neu im Fachgebiet Chirurgie

Ab sofort gelten die neuen Verordnungsausnahmen für Lipidsenker

Freie Fahrt für Lipidsenker? Das nicht, doch mit niedrigerem Schwellenwert fürs Infarktrisiko und neuen Indikationen hat der G-BA die Verordnungs-Handbremse ein gutes Stück weit gelockert.

Appendizitis und Darminfarkt durch Blinddarm-Lipom

Eigentlich sind Lipome recht harmlos. Im Zäkum können sie jedoch erhebliche Komplikationen mit Darminfarkt und Appendizitis verursachen.

Gluteuslappen nach Rektumkarzinom-Op. schützt vor Abszessen

Die Wunddeckung mit einem autologen Rotationslappen nach Entfernung eines Rektumkarzinoms konnte in einer randomisierten Studie gegenüber dem primären Wundverschluss vor allem in einer Hinsicht punkten: Sie führte deutlich seltener zu präsakralen Abszessen.

MedTalk Leitlinie KOMPAKT: S3-Leitline zu peripheren Nervenverletzungen

  • Webinar | 10.02.2025 | 13:00

Über den Weg zur finalen Fassung der S3-Leitlinie "Versorgung peripherer Nervenverletzungen" sprechen Prof. Dr. Leila Harhaus-Wähner und Ressortleiter Dr. Gunter Freese im WebTalk Leitlinie KOMPAKT, einer neuen Webcast-Serie von SpringerMedizin passend zu Ihrem Fachmagazin Orthopädie und Unfallchirurgie Mitteilungen und Nachrichten. In dem kurzen Video geht es darum, was sich im Vergleich zur vorigen Fassung der Leitlinie geändert hat, welche Aspekte für die tägliche Praxis besonders wichtig sind und was jeder gemäß Leitlinie nun anders oder besser machen sollte.
