Brief summary
The aim of this study is to determine the effective nalbuphine dose in 90% of intubated patients in the ICU, including the continuous infusion dose and a bolus dose during moving to the lateral decubitus position. Pain will assessed using a Behavioural Pain Scale (BPS) requiring a score of 3-4.
Detailed description
The continuous nalbuphine infusion dose starts at 100ug/kg/h, if the BPS scores reaches 3-4, the continuous infusion dose would be decreased by 20 ug/kg/h for next patients. If not, increased by 20 ug/kg/h. The nalbuphine bolus is injected 5 min before turning the patients and the dose (starting at 0) is increased by 0.05 mg/kg, prior to each subsequent turn to lateral decubitus until a BPS score of 3-4 is obtained.
