About this study
Official title: Effects of Aminophylline Bolus on Eleveld and Schnider TCI (Target Controlled Infusion) Concentrations at Start and End of Burst Suppression Occurence and on BIS (Bispectral Index) During the Induction Phase of Total Intravenous Anaesthesia With TCI
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.

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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
AminophyllineDrug
Patients will be observationally included in the Aminophylline or not Aminiophylline group depending on anesthesiologist's discretion.
| Study group | Role | What they receive |
|---|---|---|
| Aminophylline | Patients who received Aminophylline bolus (4 mg/kg) at Burst Suppression occurence during induction of general anesthesia conducted with Eleveld TCI model Receives: Drug: Aminophylline | |
| Not Aminophylline | Patients who did not received Aminophylline bolus (4 mg/kg) at Burst Suppression occurence during induction of general anesthesia conducted with Eleveld TCI model |
What is being measured
The primary outcome is the main question the study is designed to answer.
Correlation between Concentration at the effector site of Propofol after Aminophylline bolus during Burst Suppression occurence
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
Measured: Authors 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

Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Correlation between Concentration at the effector site of Propofol after Aminophylline bolus during Burst Suppression occurence (time frame: Authors 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). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Apr 2024.
