Core Tip

Core Tip: First, target controlled infusion (TCI) is claimed to provide an optimal sedation regimen. Secondly, little is known about the differences of time of sedation and propofol dosage between nurse-administered intermittent bolus propofol sedation and TCI. Thirdly, sedation using TCI for gastrointestinal (GI) endoscopy reduces the dose of propofol necessary per minute of endoscopy (8.2 ± 2.7 mg/min vs 9.3 ± 3.4 mg/min; P = 0.046). Fourthly, sedation using TCI for GI endoscopy could have an impact on propofol total dosage on prolonged endoscopy procedures. Fifthly, this may translate into less adverse events and higher safety when using TCI in prolonged procedures.
