This algorithm for managing postoperative pain is based on the PROSPECT recommendations and illustrates the different treatment pathways for low- (green) and high- (yellow) risk patients, as well as describing the steps of the peri-operative pathway/therapies that apply to all patients (blue). Therapies that are not recommended are also indicated (grey).
a Low-risk patients are otherwise healthy patients who are not considered to be at a higher risk than is typically associated with anaesthetic or analgesic agents.
b High-risk patients are those considered to be at a high risk of adverse effects from inhalation anaesthetics and high-dose opioids, e.g. those at risk of organ dysfunction or undergoing extensive surgery for malignancy.
