Propofol
PROPOVAN® (Propofol Injection) is an intravenous anaesthetic agent which is chemically unrelated to other anaesthetics.
PROPOVAN (Propofol Inj.) is white, opaque liquid for intravenous injection contain-ing 10 mg Propofol per ml. The vehicle contains glycerol, purified egg lecithin, sodium hydroxide, soybean oil and water. PROPOVAN (Propofol Inj.) is an intrave-nous Anaesthetic agent which is chemically unrelated to other anesthetics. Induc-tion of anesthesia with PROPOVAN (Propofol Inj.) is rapid, and maintenance can be achieved by either continuous infusion or intermittent bolus injections, with either nitrous oxide or opioids used to provide analgesia.
1. Induction of general anesthesia
(a) Adults
In unpremedicated and in premedicated patients, it is recom-mended that PROPOVAN (Propofol Inj.) should be titrated [approximately 4 ml (40 mg) every 10 seconds in an average healthy adult] against the response of the patient until the clinical signs show the onset of anesthesia. Most adult patients aged less than 55 years are likely to require 2.0 to 2.5 mg/kg of PROPOVAN (Propo-fol Inj.). Above this age, the requirement will generally be less. In patients of ASA Grades 3 and 4, lower rates of administration should be used [approximately 2 ml (20 mg) every 10 seconds].
(b) Elderly Patients
PROPOVAN (Propofol Inj.) should be titrated against the response of the patients. Patients over the age of 55 years may require lower doses of PROPOVAN (Propofol Inj.) for induction of anesthesia.
(c) Children
PROPOVAN (Propofol Inj.) is not recommended for induction of anesthesia in children less than 3 years of age.
When used to induce anesthesia in children, it is recommended that PROPOVAN (Propofol Inj.) be given slowly until the clinical signs show the onset of anesthesia. The dose should be adjusted for age and/or weight. Most patients over 8 years of age are likely to require approximately 2.5 mg/kg of PROPOVAN (Propo-fol Inj.) for induction of anesthesia. Under this age the requirements may be more. Lower dosage is recommended for children of ASA grades 3 and 4.
2. Maintenance of general Anesthesia
Adults (Including Elderly Patients)
Anesthesia can be maintained by administering PROPOVAN (Propofol Inj.) either by continuous infusion or by repeat bolus injections to prevent the clinical signs of light anesthesia. Recovery from anesthesia is typically rapid and it is therefore important to maintain PROPOVAN (Propofol Inj.) administration until the end of the procedure.
(a) Continuous infusion
The average rate of administration varies considerably between patients, but rates in the region of 4 to 12 mg/kg/hr usually maintain satisfactory anesthesia. Slightly higher rates of administration may be required for 10 to 20 minutes after induction of anesthesia.
(b) Repeat bolus injections
If a technique involving repeat bolus injections is used, increments of 25 mg (2.5 ml) to 50 mg (5 ml) may be given according to clinical need.
PROPOVAN (Propofol Inj.) may be administered via a Y-piece close to the injection site into infusions of Dextrose 5%, Sodium Chloride 0.9%, or Dextrose 4% with Sodium Chloride 0.18%. Supplementary analgesic agents are generally re-quired in addition to PROPOVAN (Propofol Inj.). Nothing except Dextrose 5% should be used for dilution of PROPOVAN (Propofol Inj.).
(c) Children
PROPOVAN (Propofol Inj.) is not recommended for maintenance of anesthesia in children less than 3 years of age.
Anesthesia can be maintained by administering PROPOVAN (Propofol Inj.) by infusion of repeat bolus injection to prevent the clinical signs of light anesthesia. The required rate of administration varies considerably between patients, but rates in the region of 9 to 15 mg/kg/hour usually achieves satisfactory anesthesia.
3. Sedation during Intensive Care
(a) Adults (Including Elderly Patients)
When used to provide sedation for ventilated patients undergoing intensive care, it is recommended that PROPOVAN (Propofol Inj.) be given by continuous infusion. The infusion rate should be adjusted according to the depth of sedation required, but rates in the region of 0.3 to 4.0 mg/kg/hr should achieve satisfactory sedation. Rate of infusion greater than 4.0 mg/kg/hr is not recommended.
PROPOVAN (Propofol Inj.) may be diluted with 5% Dextrose (See Dilution and co-administration table below).
It is recommended that blood lipid level should be monitored when PROPOVAN (Propofol Inj.) is administered to patients who are at particular risk of fat overload. Administration of PROPOVAN (Propofol Inj.) should be adjusted appro-priately 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 PROPOVAN (Propofol Inj.) formulation. One ml of PROPOVAN contains approximately 0.1 g of fat.
Although no causal relationship has been established, serious adverse events (including fatalities) have been observed from spontaneous reports of unlicensed use. These events were seen most often in children with respiratory tract infections when doses given in excess of those recommended for adults.
(b) Children
PROPOVAN (Propofol Inj.) is not recommended for sedation in children as safety and efficacy have not been demonstrated.
4. Sedation For Surgical And Diagnostic Procedures
(a) Adults
To provide sedation for surgical and diagnostic procedures, rates of administration should be individualized and titrated to clinical response. Most patients would require 0.5 mg/kg to 1 mg/kg of PROPOVAN (Propofol Inj.) over 1 to 5 min. for onset of action.
Maintenance of sedation may be accomplished by titrating PROPOVAN (Propofol Inj.) infusion to the desired level of sedation. Most patients will require 1.5 to 4.5 mg/kg/hr. In addition to the infusion, bolus administration of 10 to 20 mg may be used if a rapid increase in the depth of sedation is required. In patients of ASA
Grade 3 and 4, the rate of administration and dosage may need to be reduced.
(b) Elderly Patients
PROPOVAN (Propofol Inj.) should be titrated against the response of the patients over the age of about 55 years, may require lower doses of PROPOVAN (Propofol Inj.) for sedation for surgical and diagnostic procedures.
(c) Children
PROPOVAN (Propofol Inj.) is not recommended for sedation in children as safety and efficacy have not been demonstrated.
PROPOVAN (Propofol Inj.) should only be administered through a filter with a pore size of 5μ or greater.
PROPOVAN (Propofol Inj.) has no analgesic properties and therefore sup-plementary analgesic agents are generally required in addition to PROPOVAN (Propofol Inj.). PROPOVAN (Propofol Inj.) has been used in association with spinal and epidural anesthesia and with commonly used premedications, neuromuscular blocking drugs, inhalational agents and analgesic agents, no pharmacological incompatibility has been encountered. Lower dose of PROPOVAN (Propofol Inj.) may be required where general anesthesia is used as an adjunct to regional Anaesthetic technique.
PROPOVAN (Propofol Inj.) can be used for infusion undiluted from glass containers and plastic syringe, or diluted with 5% Dextrose intravenous infusion only, in PVC infusion bags or glass infusion bottles Dilutions, which must not exceed 1 in 5 (2 mg Propofol per ml) should be prepared aseptically immediately before admini-stration and must be used within 6 hours of preparation. It is recommended that, when using diluted PROPOVAN (Propofol Inj.) the volume of 5% Dextrose removed from the infusion bag during the dilution process is totally replaced in volume by PROPOVAN (Propofol Inj.) emulsion. The dilution may be used with a variety of infusion control techniques, but a given set used alone will not avoid the risk of accidental, uncontrolled infusion of large volumes of diluted PROPOVAN (Propofol Inj.). A burette, drop counter or volumetric pump must be included in the infusion line. The risk of uncontrolled infusion must be taken into account when deciding the maximum amount of PROPOVAN (Propofol Inj.) in the burette. When PROPOVAN (Propofol Inj.) is used undiluted to maintain anesthesia, it is recom-mended that equipments such as drop counters, syringe pumps or volumetric infusion pumps should always be used to control infusion rate.
In order to reduce pain on initial injection, PROPOVAN (Propofol Inj.) may be mixed with preservative free lignocaine injection 0.5% or 1% (See Dilution and Co-administration table below).
