Opioid requirement
Opioid Consumption
Also searched as Opioid Consumption.
A lower requirement is not a softer outcome. It is the clearest available signal that something else carried part of the load.
In depth
The quantity of opioid analgesia a person requires — a direct measure of how much pain was left unhandled.
What it drives
It reduces Sleep.
In a placebo-controlled crossover sleep-laboratory study, intravenous morphine (0.1 mg/kg) reduced slow-wave (deep) sleep and REM sleep and increased light stage 2 sleep in healthy pain-free adults, so opioid exposure degraded sleep architecture. doi 10.1093/sleep/28.6.677 · PMID 16477954
