Quantitative Evaluation of Pain with Pain Index Extracted from Electroencephalogram.
The current pain assessment methods are strongly subjective and easily affected by outside influences, and there is an urgent need to develop a reliable objective and quantitative pain-monitoring indicator. The aim of this study was to evaluate the feasibility of using Pain index (Pi) to assess pain symptoms in pain patients. ⋯ Pi significantly correlates with VAS/NRS score, might be used to evaluate the subjective pain symptoms in patients and has good research and application value as an objective pain assessment tool.

Quality of life and correlation with clinical and radiographic variables in patients with ankylosing spondylitis: a retrospective case series study.
Previously, many studies have evaluated quality of life (QoL) in patients with ankylosing spondylitis (AS), however, none of them specifically investigated the correlation between pain-related disability measured by Oswestry Disability Index (ODI) and QoL in AS patients. In addition, the correlation between global kyphosis (GK) in lateral plain radiographs and QoL in AS patients remains unclear up to now. Therefore, this study aimed to evaluate QoL and correlation with clinical and radiographic variables in AS patients, especially to figure out the relationship about the pain-specific disability measured by ODI, GK and QoL. ⋯ Poor QoL is significantly correlated with high disease activity, poor functional status and decreased spinal mobility in AS. GK is significantly associated with functional status, spinal mobility and QoL in AS patients. ODI, BASFI and BASMI are the major predictors of PF subscale of SF-36.

Observational StudyA targeted remifentanil administration protocol based on the analgesia nociception index during vascular surgery.
The intraoperative modulation of opioids continues to be based on clinical signs. This may result in adverse events such as sympathetic reactivity or opioid-induced hyperalgesia. Recently, the Analgesia/Nociception Index (ANI), a non-invasive 0-100 index derived from heart rate variability analysis, has been proposed for nociception assessment. However, the ability of the ANI to adequately guide intraoperative opioid administration has never been demonstrated. We designed a prospective study to evaluate the ability of the ANI to guide remifentanil administration in vascular surgery. ⋯ This prospective study demonstrated that the ANI can be used to adequately guide intraoperative remifentanil administration during vascular surgery. Such guidance resulted in low remifentanil consumption, low postoperative pain rates and low opioid rescue analgesia.

The clinical effectiveness of patient-controlled analgesia has been demonstrated in a variety of settings. However, patient-controlled analgesia is rarely utilised in the Emergency Department. The aim of this study was to compare the cost-effectiveness of patient-controlled analgesia vs. standard care in participants admitted to hospital from the Emergency Department with pain due to traumatic injury or non-traumatic abdominal pain. ⋯ Sampling variation was estimated using bootstrap methods and the effects of parameter uncertainty explored in a sensitivity analysis. The cost per hour in moderate or severe pain averted was estimated as £24.77 (€29.05, US$30.80) (bootstrap estimated 95%CI £8.72 to £89.17) for participants suffering pain from traumatic injuries and £15.17 (€17.79, US$18.86) (bootstrap estimate 95%CI £9.03 to £46.00) for participants with non-traumatic abdominal pain. Overall costs were higher with patient-controlled analgesia than standard care in both groups: pain from traumatic injuries incurred an additional £18.58 (€21.79 US$23.10) (95%CI £15.81 to £21.35) per 12 h; and non-traumatic abdominal pain an additional £20.18 (€23.67 US$25.09) (95%CI £19.45 to £20.84) per 12 h.
