Summary

Propofol is commonly used IV anesthetic, it has been formulated in a concentration of 10 mg/ml in a fat emulsion consisting of 10% soybean oil (long-chain triglycerides). When used for anesthetic induction, propofol causes pain on injection in 28%-90% of patients. pain probably results from a direct irritant effect. Several methods have been used to reduce this pain. Lidocaine pretreatment has been commonly proposed to decrease propofol induced pain, but its failure rate is between 13-32%. Dexmedetomidine is highly selective alfa-2 adrenoreceptor agonist. Alpha-2 receptors are located on blood vessels where they inhibit norepinephrine release. Investigators, therefore, speculated that dexmedetomidine could attenuate the pain due to injection of propofol. Investigators conducted a study to determine the efficacy of dexmedetomidine in decreasing pain due to injection of propofol.

Conditions

  • Pain
  • Intravenous Propofol Injection

Interventions

DRUG

I.V injection of 10 ml normal saline

Patients were randomly assigned in to three groups of 50 each using a computer-generated table of random numbers. Patients Group NS were injected intravenously with 10 ml of normal saline before injection of propofol.

DRUG

I.V injection with 0.25mic/kg of dexmedetomidine

Patients were randomly assigned in to three groups of 50 each using a computer-generated table of random numbers. Patients Group D25 were injected intravenously with 0.25mic/kg of dexmedetomidine diluted with normal saline into 10ml before injection of propofol.

DRUG

I.V injection of 0.50mic/kg of dexmedetomidine

Patients were randomly assigned in to three groups of 50 each using a computer-generated table of random numbers. Patients Group D50 were injected intravenously with 0.50mic/kg of dexmedetomidine diluted with normal saline into 10ml before injection of propofol.
