Design outcomes
Primary
| Measure | Time frame |
|---|---|
| - The absolute amount of morphine in mcg/kg/48 hours is the primary outcome measure. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary Objective(s): 1. To compare in the first 48 hrs after abdominal or non-cardiac thoracic surgery in infants less than one year of age who receive either acetaminophen IV boluses or morphine IV. a. number of patients needing extra morphine boluses. b. the incidence of opioid related adverse effects; - Vomiting - Hypotension with the need for vaso- active medication or fluid boluses. - Seizures without other demonstrable causes. - Bradycardia other than due to or directly related to the disease or operation. - Decreased gasto-intestinal motility or intestinal obstruction not directly related to the underlying diagnosis or operation and not previously existing, with the need for intervention. c. average pain scores, AUEC of pain score and percentage of abnormal scores (comfort / VAS) d. % of time patient is adequately pain free, based on pain scores. e. body part activity scores using acceleration sensor as surrogate marker of pain and pain thresholds. f. saliva cortisol levels (as surrogate marker of stress). e. renal clearance of acetaminophen and glucuronidation and sulphate formation. g. pharmacogenetic markers (e.g. CYP polymorphisms) PK-PD relationship for acetaminophen IV and morphine in this population three blood samples are taken from an indwelling arterial line. | — |
