What's the typical conversion you are using for bolus trials? During my fellowship days we used 1:300 like morphine but I always felt that it wasn't adequate. Got an urgent referral for dilaudid IT pump for terminal cancer pain with allergic reaction to po/iv morphine but not iv/PO dilaudid. The patient is on a total of 360 mg PO Oxycodone in 24 hrs with poor pain control. What would be a reasonable bolus trial dose of dilaudid?
