4.4 Special warnings and precautions for use

RIPOL 20MG/ML should be given by those trained in anaesthesia (or, where appropriate, doctors trained in the care of patients in Intensive Care).

Patients should be constantly monitored and facilities for maintenance of a patent airway, artificial ventilation and oxygen enrichment and other resuscitative facilities should be readily available at all times. RIPOL 20MG/ML should not be administered by the person conducting the diagnostic or surgical procedure.

Abuse of, and dependence on RIPOL 20MG/ML predominantly by health care professionals, have been reported. As with other general anaesthetics, the administration of RIPOL 20MG/ML without airway care may result in fatal respiratory complications.

When RIPOL 20MG/ML is administered for conscious sedation, for surgical and diagnostic procedures, patients should be continually monitored for early signs of hypotension, airway obstruction and oxygen desaturation.
During induction of anaesthesia, hypotension and transient apnoea may occur depending on the dose and use of premedicants and other agents.

Occasionally, hypotension may require use of intravenous fluids and reduction of the rate of administration of RIPOL 20MG/ML during the period of anaesthetic maintenance.

As with other sedative agents, when RIPOL 20MG/ML % is used for sedation during operative procedures, involuntary patient movements may occur. During procedures requiring immobility these movements may be hazardous to the operative site.

An adequate period is needed prior to discharge of the patient to ensure full recovery after use of RIPOL 20MG/ML Very rarely, the use of RIPOL 20MG/ML may be associated with the development of a period of post-operative unconsciousness, which may be accompanied by an increase in muscle tone.
This may or may not be preceded by a period of wakefulness. Although recovery is spontaneous, appropriate care of an unconscious patient should be administered.

RIPOL 20MG/ML induced impairment is not generally detectable beyond 12 hours. The effects of RIPOL 20MG/ML the procedure, concomitant medications, the age and the condition of the patient should be considered when advising patients on:
•   The advisability of being accompanied on leaving the place of administration.
•   The timing of recommencement of skilled or hazardous tasks such as driving.
•   The use of other agents that may sedate (Eg. benzodiazepines, opiates, alcohol).

As with other intravenous anaesthetic agents, caution should be applied in patients, with cardiac, respiratory, renal or hepatic impairment or in hypovolaemic or debilitated patients.
RIPOL 20MG/ML clearance is blood flow dependent, therefore, concomitant medication that reduces cardiac output will also reduce RIPOL 20MG/ML clearance.

RIPOL 20MG/ML lacks vagolytic activity and has been associated with reports of bradycardia (occasionally profound) and also asystole. The intravenous administration of an anticholinergic agent before induction, or during maintenance of anaesthesia should be considered, especially in situations where vagal tone is likely to predominate or when RIPOL 20MG/ML is used in conjunction with other agents likely to cause a bradycardia.

When RIPOL 20MG/ML is administered to an epileptic patient, there may be a risk of convulsion.

Appropriate care should be applied in patients with disorders of fat metabolism and in other conditions where lipid emulsions must be used cautiously (see section 4.2).
Use is not recommended with electroconvulsive treatment.

As with other anaesthetics sexual disinhibition may occur during recovery.
The benefits and risks of the proposed procedure should be considered prior to proceeding with repeated or prolonged use (>3 hours) of propofol in young children (< 3 years) and in pregnant women as there have been reports of neurotoxicity in preclinical studies, see Section 5.3.

Paediatric population

The use of Propofol is not recommended in newborn infants as this patient population has not been fully investigated. Pharmacokinetic data (see section 5.2) indicate that clearance is considerably re- duced in neonates and has a very high inter-individual variability. Relative overdose could occur on administering doses recommended for older children and result in severe cardiovascular depression.

RIPOL 20MG/ML is not recommended for use in children < 3 years of age due to difficulty in titrat- ing small volumes.
Propofol must not be used in patients of 16 years of age or younger for sedation for intensive care as the safety and efficacy of propofol for sedation in this age group have not been demonstrated (see section 4.3).


Advisory statements concerning Intensive Care Unit management
Use of propofol emulsion infusions for ICU sedation has been associated with a constellation of metabolic derangements and organ system failures that may result in death. Reports have been received of combinations of the following: Metabolic acidosis, Rhabdomyolysis, Hyperkalaemia, Hepatomegaly, Renal failure, Hyperlipidaemia, Cardiac arrhythmia, Brugada-type ECG (elevated ST-segment and coved T-wave) and rapidly progressive Cardiac failure usually unresponsive to inotropic supportive treatment.
Combinations of these events have been referred to as the Propofol Infusion Syndrome.
These events were mostly seen in patients with serious head injuries and children with respiratory tract infections who received dosages in excess of those advised in adults for sedation in the intensive care unit.

The following appear to be the major risk factors for the development of these events: decreased oxygen delivery to tissues; serious neurological injury and/or sepsis; high dosages of one or more of the following pharmacological agents - vasoconstrictors, steroids, inotropes and/or RIPOL 20MG/ML (usually at dose rates greater than 4 mg/kg/h for more than 48 hours).

Prescribers should be alert to these events in patients with the above risk factors and immediately dis- continue propofol when the above signs develop. All sedative and therapeutic agents used in the inten- sive care unit (ICU), should be titrated to maintain optimal oxygen delivery and haemodynamic parameters. Patients with raised intra-cranial pressure (ICP) should be given appropriate treatment to support the cerebral perfusion pressure during these treatment modifications.
Treating physicians are reminded if possible not to exceed the dosage of 4 mg/kg/h.
Appropriate care should be applied in patients with disorders of fat metabolism and in other conditions where lipid emulsions must be used cautiously.

It is recommended that blood lipid levels should be monitored if propofol is administered to patients thought to be at particular risk of fat overload. Administration of propofol should be adjusted appropriately if the monitoring indicates that fat is being inadequately cleared from the body. If the patient is receiving other intravenous lipid concurrently, a reduction in quantity should be made in order to take account of the amount of lipid infused as part of the propofol formulation; 1.0 ml of RIPOL 20MG/ML contains approximately 0.1 g of fat.

This medicinal product contains less than 1 mmol (23 mg) sodium in 100 ml, i.e. essentially ‘sodium free’.

Additional Precautions
Caution should be taken when treating patients with mitochondrial disease. These patients may be susceptible to exacerbations of their disorder when undergoing anaesthesia, surgery and ICU care.
Maintenance of normothermia, provision of carbohydrates and good hydration are recommended for such patients. The early presentations of mitochondrial disease exacerbation and of the ‘propofol infusion syndrome’ may be similar.
RIPOL 20MG/ML contains no antimicrobial preservatives and supports growth of micro-organisms.
When RIPOL 20MG/ML is to be aspirated, it must be drawn aseptically into a sterile syringe or giving set immediately after breaking the vial seal. Administration must commence without delay. Asepsis must be maintained for both RIPOL 20MG/ML and infusion equipment throughout the infusion period.
Any infusion fluids added to the RIPOL 20MG/ML line must be administered close to the cannula site.
RIPOL 20MG/ML must not be administered via a microbiological filter.

RIPOL 20MG/ML and any syringe containing RIPOL 20MG/ML are for single use in an individual patient. In accordance with established guidelines for other lipid emulsions, a single infusion of propofol must not exceed 12 hours. At the end of the procedure or at 12 hours, whichever is the soon- er, both the reservoir of propofol and the infusion line must be discarded and replaced as appropriate.
