Study summary

Background: Large doses of propofol needed for induction and laryngeal mask (LM) insertion in children may be associated with hemodynamic sides effects. Co-induction with low doses of ketamine 0.5 mg/ kg has the advantage of reducing dose and therefore maintaining hemodynamic stability.

Aim: To examine the effect of co-induction on LM insertion, hemodynamics and recovery in children

Read the detailed description

A prospective, randomized, double-blind, controlled study was conducted including120 ASA physical status I ⁄ II unpremedicated children, aged 1-8 years. Inhalatory induction with sevoflurane at 7% to insert an intravenous canula was first used then decreased to 2%. Normal saline or ketamine (0.5 mg/kg) were administered in groups P (propofol), PK (propofol-ketamine) respectively, 1 min prior to the administration of the induction dose of propofol. Propofol 3mg/kg was used for induction in the 2 groups, LM inserted 60 s later and insertion conditions assessed. Heart rate and blood pressure were recorded immediately after propofol bolus, then after LM insertion, at the 3rd ,5th and 10th minutes later. Recovery was assessed using Steward's Score

Inclusion criteria

  • (ASA) physical status I and II
  • unpremedicated
  • ambulatory surgery

Exclusion criteria

Exclusion Criteria:

  • surgery complication
  • upper air way complications
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

Study arms

  • Placebo comparator
    P (propofol),

    normal saline is injected 01 min before induction with propofol 3 mg/kg. After 60 seconds, an experimented anesthesiologist evaluated the LM conditions insertion.

    Drug: Ketamine

  • Active comparator
    PK (propofol-ketamine)

    we inject 0.5 mg/kg of ketamine 01 min before induction with 03 mg/kg of propofol .Sixty seconds after, an experimented anesthesiologist evaluated the LM conditions insertion.

    Drug: Ketamine

Interventions

  • use a low dose 0.5 mg/kg of ketamine in coinduction with propofol in children induction anesthesia

    Also known as: co-induction ketamine propofol
