Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Percutaneous dilatational tracheostomy (PDT) is a common bedside alternative to surgical tracheostomy in intensive care unit patients. Intracranial pressure measurement is a vital parameter that should be monitored when performing any procedure including PDT in these patients. During PDT, changes in intracranial pressure may occur depending on the position applied, hypercarbia and hypertension that may develop during the procedure. However, the effect of PDT procedure on intracranial pressure is controversial. It is imperative to ascertain the impact of PDT on intracranial pressure, along with the factors that influence its fluctuations during the procedure. This is of particular significance in order to avert the occurrence of deleterious conditions that may be engendered by elevated intracranial pressure. The aim of current study was to evaluate the effect of PDT procedure on intracranial pressure.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Since the study is a prospective observational study, the investigators will not be the decision-making physicians about the treatments applied to the patients. The optic nerve sheath diameter measurement method by ultrasonography will be used to determine intracranial pressure.Intracranial pressure measurement will be performed in neutral position before PDT, after the patient is positioned for the procedure, immediately after the procedure and immediately after the patient is placed in neutral position. Demographic characteristics, comorbidity status, PDT indication, intensive care unit hospitalisation diagnosis, intracranial pathology data, haemodynamic data, arterial blood gas parameters will be recorded.
