PAIN MANAGEMENT
PRiNCiPLES OF PAiN MANAGEMENT
The experience of pain includes the patient’s emotional reaction to it and is influenced by many factors, including the patient’s prior experiences with pain, meaning given to the pain, emotional stresses, and family and cultural influences. Pain is a subjective phenomenon, and clinicians cannot reliably detect its existence or quantify its severity without asking the patient directly. A useful means of assessing pain and evaluating the effectiveness of analgesia is to ask the patient to rate the degree of pain along a numeric or visual pain scale (Table 5-1).
General guidelines for management of pain are recommended for the treatment of all patients with pain (Table 5-2). Clinicians should ask about the nature, severity, timing, location, quality, and aggravating and relieving factors of the pain. Distinguishing between neuropathic and nociceptive (somatic or visceral) pain is essential to proper tailoring of pain treatments. The goal of pain management is properly decided by the patient. Some patients may wish to be completely free of pain even at the cost of significant sedation, while others will wish to control pain to a level that still allows maximal functioning.
