Though, depending on the context, remifentanyl is the ideal opioid because of its half life, we must not forget the usefulness of other opioids that can be used safely as long as we know their pharmacokinetics With the advent of sodium thiopental inintravenous anesthesia became popular. These models can be of one or several compartments.
TCI compared with manually controlled infusion of propofol: This situation becomes even more complex when administering multiple doses and this is why the accuracy of this phase is poor. Manual compared with target-controlled infusion of propofol. Anestesia basada en analgesia. Afterwards the infusion rate changes every 10 minutes, which corresponds to points C, D, E and F.

When injecting an intravenous drug aimed at a specific action, this can be done following the different phases of the drug administration: This means a fafmacocinetica. Changes in drug vehicle may alter the pharmacokinetics and result in different distribution and elimination rates of propofol.
The value of these nomograms has already been published in the Colombian Journal of Anesthesiology RCAwhich requires pro;ofol practical approximation in the way these concepts should be used- efficiently and with confidence. For Schnider V1 is age-dependent and as mentioned before, as we age, V1 decreases. Pharmacokinetic models for propofol–defining and illuminating the devil in the detail.
A search of the indexed literature was done to identify educational and illustrative articles about total intravenous anesthesia concepts and pharmacokinetics. The laryngeal mask airway. Gupta D, Henthorn T. Via this technique one achieves the intubation dose and maintains the desired concentration.
Therefore, as it farmwcocinetica necessary to know what remifentanil CP is required in accordance with the moment of surgery and the type of intervention, it is also imperative to know which propofol CP is adequate:.
As a result, very few institutions have a TCI for administering total intravenous anesthesia.

They have a large ke0 and a short hysteresis and consequently, a fast onset to allow for plasma concentration adjustments within relatively narrow therapeutic ranges, providing a flexible treatment strategy. Nomograms have farmacocineticca variables:
