The drug Propofol-Binergia is combined with spinal and epidural anesthesia; with drugs commonly used for premedication; with muscle relaxants, means for inhalation anesthesia and analgesics, while there was no pharmacological incompatibility. Lower doses of Propofol-Binergia may be required in cases where general anesthesia is used as a supplement to the methods of regional anesthesia used.
The dose of the drug must be selected individually, taking into account the premedication and the patient's response.
ADULTS
Induction of general anesthesia
Propofol can be used to induce anesthesia through slow bolus injections or infusion. Regardless of whether premedication has been or is not performed, it is recommended to titrate the dose of the drug (as a bolus injection or infusion of approximately 40 mg (4 mL) every 10 seconds for adult patients with satisfactory health status), depending on the patient's response to clinical signs of anesthesia . For most adult patients under 55 years of age, the dose is 1.5 to 2.5 mg / kg. The required total dose can be reduced by reducing the rate of administration (from 2 to 5 ml (20-50 mg / min)). For patients over the age of 55 years, a dose, as a rule, is required. Patients III and IV grades on a scale ASA (American Society of Anesthesiologist - American Society of Anesthesiologists) should inject the drug at a lower rate (approximately 2 ml (20 mg) every 10 seconds).
Maintaining general anesthesia
Anesthesia can be maintained by administering Propofol-Binergia by continuous infusion or repeated bolus injections to prevent signs of insufficient anesthesia.Normalization of the state after anesthesia occurs, as a rule, quickly, so it is important to maintain the introduction of the drug Propofol-Binergia before the end of the procedure.
Continuous infusion
The required rate of administration varies considerably depending on the individual characteristics of the patients, but, as a rule, the speed within 4-12 mg / kg / h provides adequate anesthesia.
With less stressful surgical interventions, for example, minimally invasive, usually a maintenance dose of about 4 mg / kg / h is usually sufficient.
Elderly patients, patients with unstable general condition, with impaired cardiac function, hypovolemia and patients III - IV classes of risk by classification ASA the dose can be reduced (the recommended dose is 4 mg / kg / h), depending on the severity of the condition and the method of anesthesia.
Repeated bolus administration
If a technique involving repeated bolus injections is used, then the administration of increasing doses from 25 mg (2.5 ml) to 50 mg (5 ml) is made according to clinical need.
In elderly patients, rapid bolus administration (single or multiple) is not advisable, since it can lead to depression of cardiac and respiratory activity.
Sedation during intensive care
To ensure a sedative effect in intensive care, it is recommended to administer the drug by continuous infusion. The rate of infusion should depend on the necessary depth of sedation. For most patients, a sufficient sedative effect can be achieved with the administration of the drug at a dose of 0.3-4 mg / kg / h. The upper limit of the rate of infusion to ensure sedation in resuscitation should not exceed 4 mg / kg / h, unless the benefit exceeds the risk of side effects. The drug Propofol-Binergiya is not indicated for providing a sedative effect in the intensive care of patients under the age of 16 years.
The introduction of the drug with the help of the ICC system (infusion of the target concentration) for sedation of patients during intensive therapy is not recommended.
Sedation of patients who are conscious, during surgical and diagnostic procedures
The introduction of the drug Propofol-Binergia with the help of the ICC system for sedation with preservation of consciousness is not recommended.
To ensure sedation during surgical or diagnostic procedures, propofol can be used alone or in combination with local or conduction anesthesia.The rate of drug administration and dose should be selected individually and titrated depending on the clinical response. For most patients, the onset of a sedative effect requires the administration of 0.5 to 1 mg / kg for 1 to 5 minutes.
Maintenance of sedative effect can be provided by titrating infusion of the drug to the required level of sedative effect; for most patients, 1.5 to 4.5 mg / kg / h is needed. If a rapid increase in the depth of sedation is required, bolus administration of 10 to 20 mg may be recommended as an adjunct to the infusion. For patients older than 55 years and for patients III - IV class of risk by classification ASA it may be necessary to reduce the dose and the rate of administration of the drug.
CHILDREN
The introduction of propofol to children with the help of the ICC system is not recommended for any indication.
Induction of general anesthesia
Propofol-Binergiya is not recommended for the induction of anesthesia in children under 1 month of age. When used as an initial anesthetic for children, the drug Propofol-Binergia is recommended to be administered slowly until the appearance of clinical signs of anesthesia.The dose should be adjusted according to age and / or body weight.
For most children from the age of 8 years, in general, approximately 2.5 mg / kg is needed for induction. For children under the age of 8 years, especially at the age of 1 month to 3 years, the required dose may be higher (2.5-4 mg / kg).
For children III - IV classes of risk by classification ASA reduced doses are recommended.
Maintaining general anesthesia
Propofol-Binergiya is not recommended for maintenance of anesthesia in children under 1 month of age.
Anesthesia can be maintained by administering Propofol-Binergia as a continuous infusion or repeated bolus injections to prevent clinical signs of insufficient anesthesia. The required rate of administration varies considerably depending on the individual characteristics of the patients, but the rate within 9-15 mg / kg / hour, as a rule, ensures the maintenance of adequate anesthesia.
For children aged 1 month to 3 years, compared with older children, higher doses of the drug may be required within the recommended dose range. The dose should be adjusted individually and with special attention to monitor the adequacy of anesthesia.
For children III - IV classes of risk by classification ASA lower doses are recommended.
Sedation during intensive care
Propofol is not recommended for sedation in children, since its safety and efficacy in this application have not yet been confirmed. In the unlicensed use of propofol, serious adverse events were noted, including deaths, although there was no causal relationship with the use of the drug. These adverse events were most often observed in children with respiratory tract infections that received doses exceeding the recommended doses for adults.
Sedation for surgical and diagnostic procedures
Propofol is not recommended for use in children under 1 month of age.
To ensure sedation in surgical or diagnostic procedures, propofol can be used in isolation or in combination with local or conduction anesthesia. The rate of drug administration and dose should be selected individually and titrated depending on the clinical response. For most patients, the onset of a sedative effect requires the administration of 1 to 2 mg / kg for at least 1 minute.Maintenance of sedative effect can be provided by titrating infusion of the drug to the required level of sedative effect; for most patients, from 1.5 to 9 mg / kg / h is needed. In addition to infusion, a bolus dose of up to 1 mg / kg can be given if a rapid onset of a deep sedative effect is necessary.
Patients III - IV class of risk by classification ASA it may be necessary to reduce the dose and the rate of administration of the drug.
Method of administration
For intravenous administration.
Only for single use.
Ampoule should be shaken before use.
If the shaking of the emulsion is observed after shaking, the preparation should not be used. Use only if the emulsion is homogeneous and the packaging is intact.
Before use, the neck of the ampoule should be treated with alcohol.
Since Propofol-Binergia is a fat emulsion that does not contain preservatives and does not have antimicrobial activity, the preparation can serve as a favorable medium for rapid growth of microorganisms.
Emulsion should be typed in a sterile syringe or dropper immediately after opening the package.The preparation should be started without delay.
During the entire period of administration of the drug Propofol-Binergia, you must follow the rules of aseptic work with the drug and the system for parenteral infusion.
With the joint administration of the drug Propofol-Binergia with other drugs and solutions in the same system, the introduction of the latter is recommended through a tee with a valve in the immediate vicinity of the site of administration of the drug. Propofol-Binergia can not be administered via a microbiological filter.
The drug Propofol-Binergia and any infusion system containing Propofol-Binergia are intended only for single-entry introduction of one patient.
Any residues of the Propofol-Binergia emulsion should be disposed of after use. Propofol-Binergia can be used for infusions in a diluted and undiluted form. When administering Propofol-Binergia in the form of infusions, it is recommended to use devices to control the rate of administration (burettes, droppers, syringe pumps, including ICC systems) and volumetric pumps. The compatibility of electronic equipment must be ensured.
Infusion of undiluted preparation Propofol-Binergia
The total time of administration of the undiluted drug through one infusion system should not exceed 12 hours. After 12 hours of use, the infusion system containing Propofol-Binergium or the container with the drug should be replaced.
Infusion of a diluted preparation of Propofol-Binergia
For infusions of a diluted preparation of Propofol-Binergia, it is recommended to use devices to control the speed of infusions and to prevent accidental administration of large volumes of the drug. When choosing the maximum volume of diluted drug in a burette, the risk of uncontrolled administration should be taken into account. Propofol-Binergium should not be mixed before administration with other solutions except 5% dextrose solution for intravenous administration and 0.9% sodium chloride solution for intravenous administration. Maximum dilution should not exceed 1 part of the preparation in 4 parts 5 % dextrose solution for intravenous administration or 0.9% sodium chloride solution for intravenous administration (the final concentration of propofol in the diluted solution should be at least 2 mg / ml).Preparation should be carried out in aseptic conditions immediately before administration, the mixture should be used within no more than 6 hours after preparation.
Simultaneous administration of the drug with 5% dextrose solution for intravenous administration, 0.9% sodium chloride solution for intravenous administration, or 0.18% sodium chloride solution for intravenous administration in a 4% dextrose solution for intravenous administration via a tee with a valve in close proximity to site of the introduction of Propofol-Binergia.
Painful sensations in the administration of propofol can be reduced by joint administration with lidocaine. Immediately prior to administration, the induction dose of Propofol-Binergium can be mixed in a syringe with 1% lidocaine solution for injections without preservatives in the following proportion: 20 parts of Propofol-Binergia and up to 1 part 1 % lidocaine solution. Preparation should be carried out in aseptic conditions immediately before administration, the mixture should be used within no more than 6 hours after preparation. Use lidocaine for breeding children under 12 years with caution.
Attention: lidocaine contraindicated in patients with hereditary acute porphyria! Muscle relaxants, such as atrakurium and myvacurium, can be administered through the infusion system used to administer the Propofol-Binergia preparation only after it has been rinsed.
The drug Propofol-Binergiya can be administered with the help of infusion pumps or manually. In the case of the use of infusion pumps, appropriate compatibility must be ensured.
Infusion by target concentration (CI) - the introduction of the drug Propofol-Binergia with the help of infusion pumps.
The introduction of the drug Propofol-Binergia using the ICC system is limited to introduction into general anesthesia and its maintenance in adults. ICC is not recommended for sedation during intensive care and for sedation in diagnostic and surgical procedures, as well as sedation in children.
The preparation of Propofol-Binergia can be administered by the ICC method only with the help of a suitable ICC system having the appropriate software. Users should be familiarized with the manual for working with the infusion pump and with the introduction of the drug Propofol-Binergia by the ICS method.
This system enables the anesthesiologist to achieve and control the desired rate of anesthesia and depth of anesthesia by setting and controlling the target (predicted) concentration of propofol in the patient's blood.
Different methods of pumping systems should be taken into account, i.e. the ICC system assumes that the initial concentration of propofol in the patient's blood is 0. Therefore, for patients receiving propofol earlier, it is possible to choose lower initial target concentrations at the beginning of the administration of the preparation Propofol-Binergia by the ICS method. Also, it is not recommended to resume the operation of the ICC system in the previous mode after it is turned off. Guidance on the selection of target concentrations of propofol is presented below. Due to the individual differences in the pharmacokinetics and pharmacodynamics of propofol in patients who received premedication and who did not receive it, the target concentration of propofol should be titrated depending on the patient's clinical response in order to achieve the required depth of anesthesia.
Introduction to general anesthesia and maintenance by means of CIs
In adult patients under 55 years of age, anesthesia can usually be achieved by targeting propofol concentrations of 4 to 8 μg / ml. The initial target concentration of propofol 4 μg / ml is recommended for patients who have been premedicated, a concentration of 6 μg / ml is recommended for patients without premedication. The time of administration to anesthesia at these target concentrations is typically 60 to 120 seconds. Higher values will lead to faster administration to anesthesia, but may be associated with more severe hemodynamic depression and respiratory function. Smaller initial target concentrations should be used in patients over 55 years of age and in Class III and IV risk patients ASA. The target concentrations can then be gradually increased by a value of 0.5 to 1.0 μg / ml at intervals of 1 minute to achieve a gradual introduction into anesthesia. Typically, additional analgesia is required, and the amount of reduction in target concentrations to maintain anesthesia will depend on the amount of additional analgesics administered. Target concentrations of propofol in the range of 3 to 6 μg / ml usually maintain a sufficient level of general anesthesia.
The predicted concentration of propofol in the blood upon awakening is generally between 1.0 and 2.0 μg / ml and will depend on the level of analgesia during the maintenance of anesthesia.
Sedation during intensive therapy by ICP
Usually, a target concentration of propofol in the blood in the range 0.2-2.0 μg / ml is required. Administration of the drug Propofol-Binergia should be started at a low target concentration and titrate the dose depending on the patient's response to achieve the desired sedation depth.
