Abstract:
ObjectiveTo assess the degree of pain in elderly patients with mechanical ventilation in ICU using critical-care pain observation tool(CPOT) and to choose the correct sedative and analgesic method.Methods 110 elderly patients in ICU after neurosurgery were divided into three assessment stages,every stage had two record points and total six points (T1-T6):the first stage (intubation and unconsciousness,T1-T2),the second stage (intubation and consciousness,T3T4 ) and the third stage(extubation and consciousness,T5-T6 ).Among them T1,T3and T5were nonnocuity assessment points of every stage,while T2,T4 and T6 were nocuity assessment points of every stage.The assessment time was one minute at every point.After recorded at every point in second and third stages,patients were asked to use the pain intensity descriptive scale (PIDS) themselves.CPOT,heart rate and mean arterial pressure (MAP) from T1 to T6 were recorded as well as PIDS from T3 to T6 in second and third stages.Results In the three stages,CPOT〔(26.8 vs.0.54,3.36 vs.1.20,2.78 vs.0.68) scores〕,HR〔(95 vs.85,94 vs.82,94 vs.84)beat/min〕 and MAP〔(95 vs.85,95 vs.87,94 vs.87)mm Hg〕 at T2,T4and T6 were higher than T1 (t=-42.89,-55.95,-55.38),T3 (t =- 5.52,- 11.33,- 11.78) and T5 ( t =- 5.54,- 9.95,- 11.33 ) ( P＜ 0.05 ).The PIDS at T4 and T6were higher than at T3and T5in the second and third stages 〔(2.52 vs.1.69,2.12 vs.1.44)scores〕 (P＜0.05).The correlation coefficient between CPOT and PIDS at T3 and T4 in the second stage were 0.49 and 0.58,respectively (P＜0.05),and between CPOT and PIDS at T5 and T6 were 0.52 and 0.59 in the third stage,respectively (P ＜ 0.05),and they both reached moderate correlation.ConclusionsCPOT may be an effective way to assess the degree of pain in elderly patients with mechanical ventilation at present.
