Living on borrowed time: experiences in palliative care.

OBJECTIVE: To gain insight into the experiences of a palliative care patient and her husband who were living on borrowed time. METHODS: A qualitative single case design was used. Systematic content analysis of the interview data, obtained in an in-depth semi-structured interview, from the husband and wife was conducted to extract themes relating to living on borrowed time. RESULTS: Three themes were identified: shifts in the interpretation of physical signs and symptoms, altered view of the future and altered choices and priorities. CONCLUSION: The identified themes lead to a better understanding of the phenomenon of living on borrowed time. Yet, refinement of, and variation within the themes still need to be studied in order to get more grips on the themes and to be better able to help patients to integrate the 'new reality'. PRACTICE IMPLICATIONS: Our findings can be used to support professionals in the practical application of care when their patients need to integrate the 'new reality' and seek new equilibrium, e.g. converted into a conversational guide, or used for educational purposes.

Consultation in palliative care: the relevance of clarification of problems.

This study aims to determine the extent and nature of problems in palliative care that are newly identified in the consultation process and the factors influencing their identification. The consultation process includes clarification of problems mentioned by professionals requesting advice. Data are derived from the standard registration forms of Palliative Care Consultation teams. Multilevel logistic regression analysis was carried out with newly identified problem as dependent variable. Fifty seven percent of problems (n=7854) were newly identified. Most newly identified problems were related to physical and pharmacological problems. If psychosocial/spiritual problems were identified, this occurred in most cases through clarification (70%). Newly identified problems were more likely to be identified in the domain of spiritual and psychosocial problems, in bedside consultations, in requests from clinical physicians, and for patients accommodated in a hospice or hospital. Explicit clarification of problems facilitates the identification and addressing of a more comprehensive and specific scope of problems.

Outcome of transcutaneous electrical nerve stimulation in chronic pain: short-term results of a double-blind, randomised, placebo-controlled trial.

The aim of this study was to test the efficacy of shortterm transcutaneous electrical nerve stimulation (TENS) treatment in chronic pain with respect to pain intensity and patients' satisfaction with treatment results. We therefore performed a randomised controlled trial comparing TENS and sham TENS. Patients, researchers and therapists were blinded for treatment allocation. One hundred and sixty-three patients with chronic pain referred to the Pain Centre entered the study. Conventional TENS and sham TENS were applied in the segments of pain, for a period of ten days. Outcome measures were pain intensity (visual analogue scale) and patients' satisfaction with treatment result (yes or no). The proportions of patients satisfied with treatment result differed significantly for TENS compared to sham TENS (58 and 42.7% respectively, chi(2)=3.8, p=0.05). However, no differences in pain intensity were found for patients treated with TENS or sham TENS. Only for patients satisfied with treatment results pain intensity gradually decrease equally both for TENS and sham TENS with repeated treatment application.

Requests from professional care providers for consultation with palliative care consultation teams.

GOALS OF WORK: Professional care providers need a substantial basis of competence and expertise to provide appropriate palliative care. Little is known about the problems professionals experience in their palliative care provision in daily practice or about the nature of the advice and support they request from experts. Our aim was to investigate the extent to which professionals requested assistance from palliative care consultation teams and the reasons behind these requests to trace any gaps they experience in the provision of palliative care. METHODS: As part of a large national palliative care development programme, we studied requests for consultation made by professional care providers over a 2-year period. The requests for consultation were recorded on a specially developed standard registration form and classified according to 11 domains relevant to palliative care. MAIN RESULTS: Professional care providers requested 4351 consultations on account of 8413 specific problems in 11 quality-of-life and quality-of-care domains. The distribution of problems over these domains was unbalanced: 42.2% of the specific problems were physical, while the percentages of psychological, pharmacological and organizational problems were 7.7, 12.5 and 12.8%, respectively. In contrast, issues of a spiritual nature or concerned with daily functioning were raised infrequently (1.1 and 0.9%). Details of the specific problems in all the domains are described in the text and tables. CONCLUSIONS: The results of our study form a valid basis on which to develop and implement improvements in palliative care. We recommend that future well-founded policies for palliative care should incorporate palliative care consultation as well as educational and organizational interventions.

The present role of percutaneous cervical cordotomy for the treatment of cancer pain.

The results obtained by percutaneous cervical cordotomy (PCC) were analysed in 43 terminally ill cancer patients treated in our institution from 1998 to 2001. We wished to determine whether there is still a place for PCC in the actual clinical situation with its wide choice of pain therapies. All patients had severe unilateral pain due to cancer, resistant to opioids and co-analgesics. Following PCC, mean pain intensity was reduced from Numeric Rating Scale (NRS) 7.2 to 1.1. At the end of life, pain had increased to NRS 2.9. Initially following PCC a good result (NRS<3) was obtained in 95% of patients. At the end of life, a good result was still present in 69% of patients. Mean duration of survival after the intervention was 118 days (2-1460). In general, complications were mild and mostly subsided within 3-4 days. There was one case of partial paresis of the ipsilateral leg. PCC remains a valuable treatment in patients with treatment-resistant cancer pain and still deserves a place in the treatment of terminal cancer patients with severe unilateral neuropathic or incidence pain.

General practitioners (GPs) and palliative care: perceived tasks and barriers in daily practice.

BACKGROUND: General practitioners (GPs) play a crucial part in palliative care. The quality of care can be improved by investigating and addressing barriers perceived by GPs in daily practice. The aim of this study was to investigate GPs' task perception and barriers involved in palliative care. METHODS: Qualitative focus group study. We gathered together a group of GPs representing a broad range of experience in palliative care. Content analysis was performed to derive a comprehensive view of tasks and barriers in daily palliative care. RESULTS: GPs described their palliative care tasks as satisfactory and varied, but burdensome. Palliative care tasks included somatic and psychosocial care. Opinions differed with respect to whether the coordination of care belonged to the primary GP tasks. Barriers were classified according to three levels: (1) personal: barriers related to knowledge, skills, emotions; (2) relational: barriers concerning communication and collaboration; (3) organizational: barriers related to the organization of care and compartmentalization in healthcare. CONCLUSIONS: This study revealed a complex web of tasks and barriers. It may be possible to trace back a problem (lack of knowledge, for example) on the personal level to an isolated knowledge gap, but the problem may well have originated from communication or compartmentalization problems. To maintain GPs' feeling of being at ease with palliative care requires helping them acquire the appropriate balance between technical and organizational interventions and a compassionate orientation to their terminally ill patients.

Adrenalectomy affects pain behavior of rats after formalin injection.

Stressful stimuli can activate the hypothalamo-pituitary-adrenal-axis and the endogenous opioid system. In addition, corticosterone and opioid release might cause analgesia. This rat study used adrenalectomy for corticosterone withdrawal and naloxone administration for opioid antagonism in order to study pain behavior and hypophyseal hormone release in the plasma after a formalin test. Twelve days before the formalin testing, male Sprague Dawley rats underwent adrenalectomy or sham-adrenalectomy, and non-operated rats were used as reference. The number of flinches and the duration of licking or biting behavior were measured during the early and late phase. In reference and sham-operated rats, injection of formalin 5% resulted in a marked pain behavior in the early and late phase with significant increases in ACTH and corticosterone plasma levels. In adrenalectomized rats, pain behavior was decreased during both phases. Naloxone, administered before the late phase, did not alter pain behavior in sham or reference rats, whereas in adrenalectomized rats pain reactivity returned to those levels observed in reference rats. Beta-endorphin plasma levels above the detection limit were more frequently found in adrenalectomized rats. Thyrotropin and prolactin levels were not different between studied groups. We speculate that the observed reduced pain behavior in adrenalectomized rats after formalin, is the result of an increased production of pro-opiomelanocortin, the pro-drug of both adrenocorticotrophic hormone and beta-endorphin.

Lumbar segmental nerve blocks with local anesthetics, pain relief, and motor function: a prospective double-blind study between lidocaine and ropivacaine.

Selective segmental nerve blocks with local anesthetics are applied for diagnostic purposes in patients with chronic back pain to determine the segmental level of the pain. We performed this study to establish myotomal motor effects after L4 spinal nerve blocks by lidocaine and ropivacaine and to evaluate the relationship with pain. Therefore, 20 patients, of which 19 finished the complete protocol, with chronic lumbosacral radicular pain without neurological deficits underwent segmental nerve blocks at L4 with both lidocaine and ropivacaine. Pain intensity scores (verbal numeric rating scale; VNRS) and the maximum voluntary muscle force (MVMF; using a dynamometer expressed in newtons) of the tibialis anterior and quadriceps femoris muscles were measured on the painful side and on the control side. The median VNRS decrease was 4.0 (P < 0.00001; Wilcoxon's signed rank test), without significant differences between ropivacaine and lidocaine (Mann-Whitney U-test). A difference in effect on MVMF was found for affected versus control side (P = 0.016; Tukey test). Multiple regression revealed a significant negative correlation for change in VNRS score versus change in median MVMF (Spearman R = -0.48: P = 0.00001). This study demonstrates that in patients with unilateral chronic low back pain radiating to the leg, pain reduction induced by local anesthetic segmental nerve (L4) block is associated with increased quadriceps femoris and tibialis anterior MVMF, without differences for lidocaine and ropivacaine.

Quantitative sensory testing and human surgery: effects of analgesic management on postoperative neuroplasticity.

BACKGROUND: Altered central nervous system sensory processing (neuroplasticity) is a basic mechanism underlying postoperative pain that can be made visible using quantitative sensory testing. Using quantitative sensory testing, the authors investigated how perioperative analgesia affects postoperative neuroplasticity and how this relates to clinical pain measures. METHODS: Patients undergoing back surgery received placebo, fentanyl, or ketorolac (n = 15 per group) before isoflurane-nitrous oxide anesthesia. Preoperatively to 5 days postoperatively, we measured thresholds to electrical skin stimulation at the incision site, arm, and leg; pain scores; and morphine patient-controlled analgesia consumption. RESULTS: Decreased pain thresholds versus preoperatively were seen 5 days postoperatively, with decreases greater for ketorolac (-63%; P = 0.00005 vs. preoperatively) than placebo (-45%; P = 0.008 vs. preoperatively) but nonsignificant for fentanyl (-36%; P = 0.9 vs. preoperatively). Mainly nonnociceptive thresholds were increased up to 24 h postoperatively. Postoperative clinical pain measures were similar across drug groups. Postoperative pain tolerance threshold changes did not correlate with preoperative clinical pain measures but were inversely related to preoperative thresholds for placebo and ketorolac but not fentanyl. CONCLUSIONS: Without analgesia, neuroplasticity after surgery was inhibitory the first 24 h and followed at 5 days by excitation. Fentanyl efficiently preempted this hyperalgesia, but hyperalgesia was greater with ketorolac than with placebo. Clinical pain measures neither reflected the different effects of ketorolac and fentanyl on postoperative neuroplasticity nor permitted prediction of postoperative neuroplasticity. The information obtained by perioperative quantitative sensory testing is separate from and additional to that from clinical pain measures and may enable more mechanism-based approaches to surgical analgesia management in the future.

The efficacy of radiofrequency lesioning of the cervical spinal dorsal root ganglion in a double blinded randomized study: no difference between 40 degrees C and 67 degrees C treatments.

The efficacy of radiofrequency lesion treatment of the cervical dorsal root ganglion (RF-DRG) in cervicobrachialgia was investigated in 61 patients by a randomized prospective double blinded study. Before lesion treatment the putative pain provoking spinal root was identified by diagnostic blocks with a local anesthetic agent. One group of patients (n = 32, group I) was treated with a radiofrequency lesion of 67 degrees C and in a control group (n = 29, group II) a temperature of 40 degrees C was applied. Three months after treatment a significant reduction in VAS scores was demonstrated in both groups. The outcome of the treatments was identical (VAS reduction: group I, 1.7; group II, 1.9; P = 0.001). In group I a VAS reduction of 3 or more occurred in 11/31 (34%) and in group II in 11/29 (38%) of patients. A VAS reduction of 2 or more occurred in group I in 15/31 (47%) and in group II in 15/29 (51%) of patients. This study suggests that treatment with 40 degrees C radiofrequency application of the dorsal root ganglion is equally effective as treatment at 67 degrees C. Further appraisal of this treatment is required.

Methadone for phantom limb pain.

OBJECTIVE: The objective of this case series was to determine if severe phantom limb pain could be reduced with oral methadone. DESIGN: Four cases of phantom limb pain refractory to multiple treatment modalities were treated with oral methadone. SETTING: Pain clinic at a major university medical center. PATIENTS: Four patients with severe, intractable phantom limb pain. INTERVENTION: Oral methadone was administered, starting with a low dose of 2 to 5 mg twice a day or three times a day and slowly titrated upward to achieve pain relief. OUTCOME MEASURES: Repeated administration of a visual analog scale for pain. RESULTS AND CONCLUSIONS: Administration of oral methadone may be of value in the treatment of phantom limb pain; controlled clinical trials would be appropriate to verify this observation.

The role of helplessness, fear of pain, and passive pain-coping in chronic pain patients.

OBJECTIVES: The goal of this study was to examine the relative contribution of helplessness, fear of pain, and passive pain-coping to pain level, disability, and depression in chronic pain patients attending an interdisciplinary pain center. METHODS: One hundred sixty-nine chronic pain patients who had entered treatment at an interdisciplinary pain center completed various questionnaires and a pain diary. RESULTS: Helplessness, fear of pain, and passive pain-coping strategies were all related to the pain level, disability, and depression. When comparing the contribution of the predictors in multiple regression analyses, helplessness was the only significant predictor for pain level. Helplessness and the passive behavioral pain-coping strategies of resting significantly predicted disability. The passive cognitive pain-coping strategy of worrying significantly predicted depression. CONCLUSIONS: These findings indicate a role for helplessness and passive pain-coping in chronic pain patients and suggest that both may be relevant in the treatment of pain level, disability, and/or depression.
