Anesthesia Brain Monitoring, Propofol
Conditions
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 utility in decrease the timing of return of consciousness after Propofol anaesthesia with an intravenous bolus of 4 mg/kg. We aimed to compare its effect during a 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. We aimed to compare its effect during a total Intravenous Anasethesia with Target Controlled Infusion (TIVA-TCI) routinely utilized for general anaesthesia in our hospital (with Eleveld or Schnider Pharmacokinetic/Pharmacodynamic-PK/PD model). The timing from stop of propofol infusion to eye opening and return of responsiveness, the relative Concentration of Propofol (CeP) and the power spectrum of the Bispectral Index (BIS) with or without aminophylline bolus were taken into account.
Interventions
Patients will be observationally included in the Elveld TCI or Schnider TCI group and recevied or not Aminiophylline bolus. The TCI model, such as the aminophylline delivery or not, is chosen at anesthesiologist's discretion, as suggested in literature

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Correlation between Concentration at the effector site of Propofol after Aminophylline | We 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 and timing at eye opening of Propofol using the Eleveld TCI model or Schnider TCI model, after standard general anaesthesia conducted with Propofol and remifentanil delivered with target controlled infusion pumps, usually adopted in our Hospital to delivery general anaesthesia |
