Evaluation of the Relation Between Patient Fasting Time and the Occurrence of PIH (Post Induction Hypotension) - Prospective Trial

This monocentre prospective trial aims to evaluate the relationship between fasting time and the occurence of PIH (post-induction hypotension).

Detailed Description

A decrease in blood pressure (BP) after induction of general anesthesia (GA) is a common phenomenon. The etiology is multifactorial (vasodilatory and dále negative inotropic effects of anaesthetics, reduction in sympathetic tone, the effect of positive pressure ventilation and others). Relative hypovolemia due to patient fasting is one of the factors that can have a significant influence on the decrease in blood pressure after induction of GA. Different lengths of fasting may thus lead to variations in both the incidence of hypotension after induction of GA (post-induction hypotension - PIH) and the severity of the BP drop.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Post induction hypotension (PIH)
Time Frame: 1 month
The incidence of the post induction hypotension (PIH) will be assessed in the study subjects.
1 month
Seriousness of post induction hypotension (PIH)
Time Frame: 1 month
Seriousness of post induction hypotension (PIH) will be assessed to determine whether patients with longer fasting time experience a significant reduction of blood pressure after induction of general anaesthesia.
1 month
Comparison of other PIH risk factors
Time Frame: 1 month
The risk factors such as comordibity, chronic medication, type and doses of induction drugs will be compared.
1 month
