R52.9
There are numerous medical conditions associated with severe acute pain e.g. myocardial infarction, renal colic, sickle-cell crisis and intra-articular haemorrhage due to haemophilia.
The analgesic treatment for these conditions is as for patients with acute post-operative pain (see: Postoperative pain in the recovery room).
Patients should be monitored for respiratory and cardiovascular depression when IV opioids are administered.
Patients already on opioids for chronic pain, who experience an acutely painful event, may be opioid tolerant and require higher IV opioid boluses in order to control their pain.
