Influence of comorbidities on pain intensity in patients with chronic low back pain.

Objectives: Chronic pain is a complex process that can vary depending on factors such as time evolution, mood, or even previous experiences. Our objective is to describe patient's characteristics from those who were referred with a diagnosis of low back pain in their first Pain Unit (PU) visit, and identify those factors that may interfere with their pain perception.

Methods: Inferential analysis was carried out from data recorded in the PU database of the Hospital de la Santa Creu y Sant Pau in Barcelona, from November 2012 to November 2018.

[New trends in the treatment of post-operative pain in general and gastrointestinal surgery].

The correct application of multimodal analgesia appropriate to the pain intensity, the characteristics of the surgery and the hospitalisation scheme provide the key to improving the management of postoperative pain, which is currently still under treated. In highly complex surgeries the best benefit is obtained by combining systemic analgesic drugs with regional analgesia techniques. Epidural analgesia, not only provides an excellent quality of analgesia, but can prevent complications and reduce postoperative morbidity.
