Conversion Factor There is limited evidence and no consensus on the conversion factors to use for methadone. The WA State AMDG calculator uses higher conversion ratios that increase at higher doses mg ratio, mg ratio, mg , over 51 mg ratio For the dose entered, these two conversion ratios are: mg this calculator.
Is the patient co-prescribed benzodiazepines? Yes No. Use of this table for conversion from fentanyl to other opioids can overestimate the dose of the new agent and may result in an overdosage. Equianalgesic Chart. Doses listed are equivalent to 10 mg of parenteral morphine. Doses should be titrated according to individual response. Patient is receiving a total of 5 mg of parenteral hydromorphone in a hour period via a PCA pump. The goal is to convert this to oral morphine for discharge.
When converting from PCA administration, add the total amount of opioid that the patient received in the last 24 hours, including. Basal infusion. Demand boluses administered by the patient. The equianalgesic chart indicates that 1. Opioid overdose:. If given IV, each 0. Opioid-induced respiratory depression. Continue looking for other causes of sedation and respiratory depression. Special considerations. Depending on amount and type of opioid given and time interval since last opioid administration, the duration of action of some opioids may exceed that of naloxone.
