Review Protocol – Chloral Hydrate (safety)

Review questionFor children and young people under the age of 19 undergoing diagnostic or therapeutic procedures, is chloral hydrate (with or without: analgesia, another drug or psychological techniques) safe for sedation (at mild, moderate, and deep levels) in different settings?
ObjectivesTo estimate the safety of chloral hydrate.
Infants, children and young people (under 19 years) receiving sedation by any technique for painful or non-painful diagnostic or therapeutic procedures including dental surgery and minor operations carried out under local anaesthesia.
InterventionSedation for diagnostic or therapeutic procedures.
ComparisonThe following comparisons will be included.
  • intervention (including combinations) versus no intervention or placebo or usual care
  • intervention A versus B
  • intervention A + B versus B
  • pharmacological versus non-pharmacological
  • pharmacological + non-pharmacological versus non-pharmacological
  • pharmacological + analgesia versus analgesia
  • pharmacological versus general anaesthesia
  • dose A versus dose B
  • duration 1 versus duration 2
  • route of administration 1 versus 2
OutcomesAdverse events:
  • Aspiration
  • Respiratory intervention, including:
    • oral-pharyngeal airway
    • endotracheal intubation
    • assisted ventilation
  • Cardiac arrest requiring either/or:
    • external cardiac massage
    • defibrillation
  • Oxygen desaturation <90%
  • Vomiting
Search strategyThe databases searched were Medline (from 1950 to Jan 18th 2010), Embase (from 1980 to Jan 18th 2010), The Cochrane Library (all dates available to 2009 Issue 4) and CINAHL (from 1982 to Jan 18th 2010).

Studies were restricted to English language only.

Searches were not restricted by study design.
The review strategyThe review for drug safety was based upon both RCT and non RCT observational evidence. Study details and results were extracted into tables for review by the GDG. Rates of adverse events were calculated as required.
