4. pain assessment • The importance of pain assessment was identified as a necessary first step in improving the effectiveness of pain Management.

5. Principles of Assessment • Assess and reassess . • Reassess Intensity, Relief, And Side Effects. • Use verbal report whenever possible . • Document in a visible place. • Include the family.

6. history of pain assessment • In 1992 and again in 1994 ,the Agency for Health Care Policy and Research (AHCPR) published guideline for the treatment of acute pain and cancer pain. • In 1999, the Joint Commission on the Accreditation of Healthcare Organizations (JCAHO) released its standards on pain management .

7. The Role of Nursing in Pain assessment • Onset • Location • Duration • Radiation • Influence of pain in daily and quality of life

8. Measurement pain tools • One–dimensional tools • Pain rating scales : • Visual analog scale • Verbal rating scale • Numerical rating scale • Multidimensional tool • The MCGILL pain QUESTIONNARE • Initial pain assessment by McCaffery and pasero

9. Visual analogue scale(VAS) • A horizontal or vertical line for the patient to rate current pain level. • Patient can communicate by pointing • Simple, easy to use • Needs to understand concept of rating pain. • Dependent on patient's prior pain experiences

10. Visual analogue scale The patient is asked to place a mark along the line to indicate the current pain level.

11. Advantage of Visual analogue scale • Simple • quick to administer • and may be used before, during, and following treatment . • The scales may also be completed throughout the course of a day to assess change in pain intensity relative to activity or time of day.

12. limitation of visual analog scale • Difficultly with administration in patient who has perceptual-motor problems . • The major disadvantage of VAS is the assumption that pain is a unidimensional experience.

13. Verbal and Numeric Rating Scale numeric rating scales •Verbal rating scales

14. PAIN INTENSITY SCALE

15. McGill Pain Questionnaire (MPQ) • The McGill Pain Questionnaire, developed by Melzack (1975), was the first proper multidimensional self-report pain measuring instrument and is still the most widely used today.

16. McGill Pain Questionnaire (MPQ) • sensory: what the pain feels like physically where it is located, how intense it is, its duration and its quality (for example,burning, ‘throbbing). • affective: what the pain feels like emotionally —whether it is frightening, worrying and so on . • evaluative: what the subjective overall intensity of the pain experience is (for example, unbearable, distressing).

17. McGill Pain Questionnaire (MPQ) • Each of the three main classes was divided into a number of sub-classes (sixteen in total).

18. McGill Pain Questionnaire (MPQ) • Melzack and Torgerson (1971) then asked a sample of doctors, patients and students to rate the words in each sub-class for intensity. The first 20 questions on the McGill Pain Questionnaire consist of adjectives set out within their sub-classes, in order of intensity. Questions 1 to 10 are sensory,11 to 15 affective, 16 is evaluative and 17 to 20 are miscellaneous.

19. McGill Pain Questionnaire (MPQ) • codes E for pain on the surface of the body • codes I for internal pain • Codes and EI for both external and internal) • indicate present pain intensity (PPI) on a 6-point verbal rating scale. • Finally, patients complete a set of three verbal rating scales describing the pattern of the pain.

20. McGill Pain Questionnaire (MPQ) • Scores are given for the different classes (sensory, affective, evaluative and miscellaneous), and also a total score for all the sub-classes. • Based on this, a pain rating index (PRI) is calculated

21. affective sensory Pattern E&I evaluated PPI miscellaneous

34. What dose your pain feel like? What dose your pain change with time? How strong your pain feel like?

35. Interpretation: • minimum pain score: 0 (would not be seen in a person with true pain) • maximum pain score: 78 • The higher the pain score the greater the pain.

36. Comparison of pain scores using MPQ obtained from women during labor , And from patients in a general pain clinic and an emergency department.

37. Criticisms • the need to have extensive understanding of the English language. • Need to time consuming • sufficient attention span • normal cognitive state.

38. McGill short painquestionnaire • Measures quality of pain • Uses 15 descriptor words to measure sensory and affective dimension of pain. • Can be used in conjunction with a pain intensity scale Gives more information about the patient's pain.

39. THE SHORT-FORM McGill PAIN QUESTIONNAIRE When it use?. • when the time to obtain information from patients is limited • when more information is desired than that provided by intensity measures such as the VAS or NRS.

40. Intensity scale Sensory dimension Affective dimension VAS Present pain intensity

41. PRI –T SCORES Comparison of total pain rating index (PRI-T)scores using the (SF-MPQ) for acute and chronic pain conditions. from various pain condition are as follows: labour pain ,musculoskeletal pain and postsurgical pain. abdominal hysterectomy ,acute headache ,herpes zoster and postherapetic neuralgia ,mucositis , angioplasty sheath removal, fibromyalgia and rheumatoid arthritis, atypical facial pain ,artheritis, osteoarthritis and chronic cancer pain.

42. PAIN ASSESSMENT inless responsive or unconscious With patients who are less responsive or unconscious the nurse must look to additional pain indicators.

43. Altered body movements showing restlessness • vocalizations (e.g. 'moaning and groaning) • and facial expressions (grimacing or clenched teeth)

44. Changes in physiological parameters ? • The Changes occur in physiological parameters, including cardiovascular (elevated blood pressure and heart rate)and respiratory but are not always accurate due to the underlying or drug therapy, and should be used with other forms of assessment.
