Effects of Aminophylline Bolus on TCI (Target Controlled Infusion) Concentrations at Burst Suppression Occurence

Completed
Conditions
Anesthesia Brain Monitoring
Interventions
Registration Number
NCT06134037
Lead Sponsor
University of Padova
Brief Summary

Aminophylline is an intravenous drug commonly utilized for asthma. However, some preclinical studies and few case reports and case series have described its effects in lightining the anesthestic plan during Propofol anaesthesia with an intravenous bolus of 4 mg/kg.

Authors aimed to compare its effect during accidental episodes of Burst Suppression during the induction phase of total Intravenous Anaesthesia with Target Controlled Infusion (TIVA-TCI) routinely utilized for general anaesthesia in our hospital.

Detailed Description

Aminophylline is an intravenous drug commonly utilized for asthma. However, some preclinical studies and few case reports and case series have described its utility in decrease the timing of return of consciousness after Propofol anaesthesia with an intravenous bolus of 4 mg/kg, and also to lightining the anestetic plan (increase in Bipectral Index - BIS- values).

Authors aimed to compare its effect during accidental Burst Suppression episodes during the induction of total Intravenous Anasethesia with Target Controlled Infusion (TIVA-TCI) routinely utilized for general anaesthesia in our hospital, with Eleveld Pharmacokinetic/Pharmacodynamic-PK/PD model).

The timing and relative Concentration of Propofol (CeP) from the start to the end of Burst suppression episodes with or without aminophylline bolus deliveres as soon as detected were taken into account.

Primary Outcome Measures
NameTimeMethod
Correlation between Concentration at the effector site of Propofol after Aminophylline bolus during Burst Suppression occurenceAuthors will collected data about Drugs concentration and BIS values during general anaesthesia. We will collect BIS and TCI Propofol values during all the duration of anesthesia, form the start of anaesthesia until the emergence from anesthesia

Discover if, after an aminophylline bolus, there are differences between Concentrations at the effector site of Propofol and timing of Burst Suppression duration during standard general anaesthesia conducted with Propofol and remifentanil delivered with target controlled infusion pumps, usually adopted in our Hospital to delivery general anaesthesia
