Optimization of Sedation Protocol for Endoscopic Procedures Using Impedance Ventilation Monitor.

• Participant gender: All

Summary

The aim of the study is to evaluate the effect of opioids administered during sedation on patients' respiratory activity (ventilation) and comfort of the operator and patient during the endoscopic procedure. A common side effect of sedation is the effect on patients' ventilation, resulting from a combination of attenuation of respiratory centre activity and loss of patent airways. Shallow sedation will reduce these risks, but in addition to patient discomfort, it also increases the difficulty or impossibility of the endoscopist to perform the procedure. Choosing the appropriate method of sedation thus fundamentally affects the course of the procedure from the point of view of both the patient and the endoscopist. The aim is to prove that sedation with propofol alone compared to sedation with propofol and fentanyl premedication leads to the need for higher cumulative doses of administered propofol, higher risk of respiratory depression and lower patient and operator comfort. In addition, the non-invasive respiratory volume monitor (ExSpiron 2Xi) will be used for standard patient monitoring during the procedure, which assesses the lung tidal volume and respiratory rate by measuring the electrical impedance of the chest. This measurement captures inadequate ventilation before saturation drops, allowing even slight differences between selected drugs to be compared.
