Rapid administration may lead to projectile vomiting and ventricula dysrhthmias.
Administration to people who are physically dependant on narcotics may cause an acute withdrawal syndrome.
In general the action of naloxone is shorter than that of the narcotic which it is reversing, thus the patient may fall back into a stupor or coma as the naloxone wears off. These patients must therefore be closely observed and the dose repeated if necessary.

Tramadol

Therapeutic Effects

Is a synthetic opioid analgesic chemically similar to natural opiods.I acts upon the central nervous system by inhibiting the re-uptake of serotonin and noradranaline, which are released by the brain in response to painfil stimuli. It also binds to the CNS mu-opiod receptor sites and so may, in theory cause respiratory depression. The analgesic effects of tramadol wear off after approximately 4 hours.

Indications for use

Moderate to severe pain in adults and children over the age of 12 years.

Contraindications for use.

Head injury with decreased Glasgow Coma scale <13

Pregnancy and breast feeding

Childbirth or threatened misscarriage

patients on monoamine oxide inhibitors (MAOI's e.g Malpan, Nardil, Parnate, Parstelin ) or having taken them in the previous two weeks.

Cautions

Epileptic patients

patient who have taken alcohol

patients already receiving opiod drugs.

patients with undiagnosed abdominal pain.

Transient nausea may occour following administration. Therefore Metoclopromide 10mg IV must be given to patients over 20 Years of age Prior to the administration of tramadol. The cannula must be flushed with normal saline and a different syringe used to administer tramadol.

Side effects

Dizziness

Nausea

Headaches and drowsiness

Occasionally vomiting and agitation

convulsions may be caused by too rapid intravenous infusion, especially in epileptics. Each bolus should be given slowly over 2-3 minutes

Constipation
