Thermographic visualization of facial vasoconstriction is associated with 30-day all-cause mortality in medical patients; prospective observational two-site cohort study.

INTRODUCTION: Quick and reliable assessment of acute patients is required for accurate triage. The temperature gradient between core and peripheral temperature could possibly instantly provide information on circulatory status. METHODS: Adult medical patients, who did not receive supplementary oxygen, attending two emergency departments, had a thermographic image taken on arrival. The association between 30-day mortality and gradients was tested using logistic regression. RESULTS: 726 patients were studied, median age was 64 years and 14 (1.9%) died within 30 days. There was a significant association between mortality and temperature gradient, comparable to vital signs, age, and clinical intuition. CONCLUSION: Temperature gradient between nose and eye had an acceptable discriminatory power for 30-day all-cause mortality.

Comparing efficacy and safety of fibrinogen concentrate to cryoprecipitate in bleeding patients: a systematic review.

BACKGROUND: Bleeding is associated with the depletion of fibrinogen, thus increasing the risk of coagulopathy, further bleeding and transfusion requirements. Both fibrinogen concentrate and cryoprecipitate replenish low plasma fibrinogen levels. This systematic review aims to identify and evaluate evidence of efficacy and safety of fibrinogen concentrate and cryoprecipitate in bleeding patients. METHOD: Cochrane Central Register of Controlled Trials (CENTRAL), Medline, EMBASE up to 2nd of March 2015 were among the electronic search strategies of randomized controlled trials and non-randomized studies with meta-analysis employed. Studies for inclusion required bleeding patients being treated with either fibrinogen concentrate or cryoprecipitate. Mortality was the primary endpoint. Secondary outcomes included bleeding, coagulopathy, transfusion requirements and clinical complications related to the intervention. PRISMA methodology, a data-extraction form and the Cochrane risk of bias tool were all employed. RESULTS: Four studies were eligible for inclusion in this systematic review; one randomized controlled trial (RCT) consisting of 66 patients and three observational studies involving 218 patients in total. No mortality was reported in the published papers. There were no differences in fibrinogen-level increase, bleeding, RBC transfusions or thromboembolic complications. The RCT showed a possible increased functional improvement of haemostasis after cryoprecipitate therapy compared to fibrinogen concentrate. CONCLUSION: The available evidence directly comparing fibrinogen concentrate to cryoprecipitate is sparse and with high risk of bias. Recommendation of one product over the other for fibrinogen substitution in the bleeding patient with acquired hypofibrinogenaemia is currently not possible. Future research should guide us towards evidence-based decisions of product superiority.

A national survey of practical airway training in UK anaesthetic departments. Time for a national policy?

The Fourth National Audit Project (NAP4) recommended airway training for trainee and trained anaesthetists. As the skills required for management of airway emergencies differ from routine skills and these events are rare, practical training is likely to require training workshops. In 2013, we surveyed all UK National Health Service hospitals to examine the current practices regarding airway training workshops. We received responses from 206 hospitals (62%) covering all regions. Regarding airway workshops, 16% provide none and 51% only for trainees. Of those providing workshops, more than half are run less than annually. Workshop content varies widely, with several Difficult Airway Society (DAS) guideline techniques not taught or only infrequently. Reported barriers to training include lack of time and departmental or individual interest. Workshop-based airway training is variable in provision, frequency and content, and is often not prioritised by departments or individual trainers. It could be useful if guidance on workshop organisation, frequency and content was considered nationally.

Chronic pain and the development of a symptom checklist: a pilot study.

BACKGROUND: There is currently no instrument to systematically assess the range of symptoms/problems and their bothersomeness in patients with chronic non-cancer pain (CNPN). Systematic assessment and prioritizing may target treatments and improve outcomes. METHODS: The authors developed a checklist of symptoms and problems, the Copenhagen Symptom Checklist (CSC), presented clinically by patients. Fifty-three items representing biological, psychological and social areas were selected. Symptom/problem severity was rated on a 5-point scale anchored at 0 = 'not at all' and 4 = 'severe'. Patients ranked the five most bothersome symptoms/problems and could add five open-ended items. Patients completed the CSC after the first visit at the multidisciplinary pain centre. RESULTS: One hundred and twelve consecutive patients completed the CSC. Eighty-nine percent scored pain as rather severe or very severe (score = 3 plus score = 4), followed by reduction in physical activity (67%), fatigue (66%) and sleep disturbance (53%). Pain and fatigue, but not reduction in physical activity, were given highest priority. Cognitive problems were important to a third of the patients. Depressive symptoms, cognitive problems and worry explained 17.5% of the total variance. Patients filled in the CSC without important loss of information, but a minority prioritized more than three areas or used the free text alternative. CONCLUSIONS: Patients prioritized pain and fatigue as the most burdensome symptoms, but reduction in physical activity and sleep problems were also highly ranked. Patients were positive to the idea of symptom reporting; however, the 53-item number in this version of CSC is larger than may be necessary.

Epidural bupivacaine and morphine plus systemic indomethacin eliminates pain but not systemic response and convalescence after cholecystectomy.

We studied 24 patients undergoing elective cholecystectomy and randomized to either conventional postoperative pain treatment, with intermittent nicomorphine (10 to 15 mg) and acetaminophen (1 gm) on request, or thoracic epidural analgesia with plain bupivacaine for 48 hours and epidural morphine 4 mg every 8 hours for 96 hours plus systemic indomethacin 100 mg every 8 hours for 96 hours. Epidural analgesia for pin prick extended from the fourth thoracic to the first lumbar nerve for 48 hours. Assessments of pain, various injury response parameters, peak flow, and subjective feeling of fatigue were performed preoperatively, 3 and 6 hours after skin incision, and 1, 2, 4, and 8 days postoperatively. The epidural analgesia-systemic indomethacin treatment eliminated postoperative pain during rest and coughing. In contrast, only a minor and clinically unimportant modulation of the conventional perioperative and postoperative changes in plasma cortisol, glucose, transferrin, orosomucoid, leukocyte and differential counts, rectal temperature, peak flow, and fatigue was observed. Our results suggest that factors other than pain per se must be controlled in order to reduce postoperative morbidity.

Severity of illness and outcome of treatment in alcoholic patients in the intensive care unit.

To study whether critically ill alcoholics were more sick and had a worse outcome than other patients treated in the intensive care unit, data were collected during the initial 24 h on 216 consecutive patients admitted to an intensive care unit. Twentysix patients (12%) met the criteria for alcohol abuse. The patients' chronic health 6 months prior to admission and the extent of physiological derangement (Acute Physiology Score and Chronic Health Evaluation (APACHE] were recorded just as the type and amount of treatment (Therapeutic Intervention Scoring System (TISS]. Alcoholics were found to be significantly more sick and had a higher mortality (50% compared to 26%) than other critically ill patients. However, when analyzing the TISS points, no difference was found between the two groups. All survivors were, every third month up to 1 year after admission, asked to fill in a questionnaire indicating their level of activity. No differences were found between the two groups 1 year after admission, but the alcoholics had lost more time due to death. It is concluded that studies with larger number of patients will reveal whether alcoholics constitute a special category of patients with a different prognosis than other ICU patients.

The functional and psychosocial status of patients with disseminated bladder cancer.

This study describes self-reported functional and psychological status of patients using The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ-C30) and relates this to the prognosis. Patients with incurable locally advanced or metastatic transitional cell cancer of the urothelial tract were prospectively included in a study of self-reported functional and psychosocial status. The study included 25 patients; 19 patients completed one or more Quality of Life Questionnaires. The median survival was 5.2 months, and there was a significant relation between functional, emotional, and social status and survival. The self-assessment of functional status was a better prognostic factor for survival than performance status evaluated by the clinician. The value of the global quality of life scale did not relate to survival after recurrence. Functional, emotional, and quality of life scales declined during the progression of the disease. The study suggests that evaluation with self-reporting questionnaires may provide the physician with useful information, and it may aid in making treatment decisions in patients with metastatic bladder cancer.

Steady-state kinetics and dynamics of morphine in cancer patients: is sedation related to the absorption rate of morphine?

Eighteen patients suffering from chronic pain due to cancer completed a balanced, double-blind, double-dummy, two period cross-over trial comparing the pharmacokinetics (PK) and pharmacodynamics (PD) of morphine and its metabolites, morphine-3-glucuronide and morphine-6-glucuronide, after administration of morphine given as controlled-release (CR) tablets (every 12 h) and immediate-release (IR) tablets (every 6 h). The same total daily dose of morphine was given in both study periods. Patients received both test formulations for 4 days and on the final day of each period, peripheral venous blood samples for analysis of morphine, morphine-3-glucuronide, and morphine-6-glucuronide were obtained. Pain intensity, sedation, and continuous reaction time (CRT) were assessed. No significant differences could be demonstrated in AUC/dose, Cmin, Cmax or fluctuation index values between the two treatments (IR and CR tablets) for either morphine or its metabolites. Tmax for morphine and its metabolites occurred significantly later after administration of CR tablets than after administration of IR tablets. There were no significant differences between the IR and the CR formulation with respect to analgesia and side effects, and there was no difference in the patients' overall impression of the two treatments. More important, there was no difference between the Tmax and the time to peak sedation after administration of IR tablets (P = 0.63). However, due to the relatively small number of patients and the variability in the data, the statistical power of the test was only 0.074. The risk of a type II error is 0.926. These data demonstrate the PK and PD similarities and differences between CR and IR morphine. They suggest that there may be a relationship between Tmax (determined by absorption rate) and sedation, but further evaluation of this potential relationship is needed.

The systemic availability of buprenorphine administered by nasal spray.

The kinetics and systemic bioavailability of intranasally administered buprenorphine have been investigated in 9 healthy volunteers in an intranasal/intravenous cross-over study. Each subject received a nominal 0.3 mg dose of buprenorphine intranasally followed one week later by a matched dose intravenously. For the intranasal administration mean tmax and mean Cmax were 30.6 min and 1.77 ng mL-1, respectively. Mean intranasal bioavailability was 48.2 +/- 8.35% (mean +/- s.e.m.) of the intravenous value. Intranasal administration may represent a valuable new delivery route for buprenorphine.

Maternal opinion about analgesia in labour and delivery. A comparison of epidural blockade and intramuscular pethidine.

In a prospective randomized study we evaluated the opinion of 97 parturients on either epidural analgesia or parenteral pethidine with respect to analgesic efficacy, general feelings and symptoms during labour and delivery. The analgesic effect of the epidural block was significantly superior to pethidine with regard to the pain score (visual analogue scale (VAS)0 during the first stage of labour (mean VAS 11 contrasting 65). Moreover, 30 (59%) women in the epidural group compared to 9 (20%) in the pethidine group had a painless labour and delivery. Significantly more parturients (37 (73%)) in the epidural group would request an epidural blockade rather than pethidine treatment (14 (30%)) in a subsequent labour. Fewer side effects were registered in the epidural group compared to the pethidine group, however only significantly concerning sleepiness. It is concluded that in this study low-dose epidural analgesia during the first stage of labour was superior to parenteral pethidine regarding pain relief and side effects.

Epidural block or parenteral pethidine as analgesic in labour; a randomized study concerning progress in labour and instrumental deliveries.

A prospective randomized study was performed to evaluate the influence of epidural analgesia compared to parenteral pethidine in parturients with pain in the first stage of labour on the progress of labour and the frequency of instrumental deliveries. There was no significant difference in the two groups in the duration of either the first or second stage of labour. The overall instrumental delivery rate was 25%, with no difference between the groups. The analgesic efficacy of the epidural blockade was significantly better than that of parenteral pethidine. We conclude that epidural bupivacaine with our technique and obstetric practice did neither prolong labour nor increase the frequency of instrumental delivery.

Randomised crossover trial of transdermal fentanyl and sustained release oral morphine for treating chronic non-cancer pain.

OBJECTIVES: To compare patients' preference for transdermal fentanyl or sustained release oral morphine, their level of pain control, and their quality of life after treatment. DESIGN: Randomised, multicentre, international, open label, crossover trial. SETTING: 35 centres in Belgium, Canada, Denmark, Finland, the United Kingdom, the Netherlands, and South Africa. PARTICIPANTS: 256 patients (aged 26-82 years) with chronic non-cancer pain who had been treated with opioids. MAIN OUTCOME MEASURES: Patients' preference for transdermal fentanyl or sustained release oral morphine, pain control, quality of life, and safety assessments. RESULTS: Of 212 patients, 138 (65%) preferred transdermal fentanyl, whereas 59 (28%) preferred sustained release oral morphine and 15 (7%) expressed no preference. Better pain relief was the main reason for preference for fentanyl given by 35% of patients. More patients considered pain control as being "good" or "very good" with fentanyl than with morphine (35% v 23%, P=0.002). These results were reflected in both patients' and investigators' opinions on the global efficacy of transdermal fentanyl. Patients receiving fentanyl had on average higher quality of life scores than those receiving morphine. The incidence of adverse events was similar in both treatment groups; however, more patients experienced constipation with morphine than with fentanyl (48% v 29%, P<0.001). Overall, 41% of patients experienced mild or moderate cutaneous problems associated with wearing the transdermal fentanyl patch, and more patients withdrew because of adverse events during treatment with fentanyl than with morphine (10% v 5%). However, within the subgroup of patients naive to both fentanyl and morphine, similar numbers of patients withdrew owing to adverse effects (11% v 10%, respectively). CONCLUSION: Transdermal fentanyl was preferred to sustained release oral morphine by patients with chronic non-cancer pain previously treated with opioids. The main reason for preference was better pain relief, achieved with less constipation and an enhanced quality of life.

[A pharmacologic respiratory stimulant, doxapram, used in acute deterioration in patients with chronic respiratory failure]. / En farmakologisk respirator, doxapram, ved akut forvaerring af kronisk respirationssvigt.

In a controlled study with random allocation, the effect of doxapram (Dopram), a respiratory stimulant, was evaluated in 25 patients with acute on chronic respiratory failure requiring ventilator support. Eleven patients were allocated to mechanical ventilation and 14 to treatment with doxapram given as a variable rate infusion. In the doxapram group only four were transferred to mechanical ventilation after 1 1/2 to three days of treatment. In these patients, the problem giving rise to the acute exacerbation, was not under control at the time of ventilator intervention. In the remainder of the group, antibiotics, diuretics and bronchodilators had successfully treated the exacerbation. All patients were discharged alive. In the doxapram-treated group duration of hospitalization was nine days compared to 14 days (median values) in the ventilator-treated group. Only minor side-effects from doxapram were observed, and it is concluded that this respiratory stimulant can be used as a primary drug in patients with acute respiratory failure and chronic airflow limitation.

[Cerebral dysfunction after prolonged use of opioids]. / Cerebral dysfunktion ved langtidsbrug af opioider.

Cerebral dysfunction due to long-term treatment with opioids is a problem of increasing relevance because of the rapidly growing use of opioids. A review of psychomotor and cognitive test methods is given, including their application in patients on long-term opioid treatment. The findings of the most valid studies on cancer patients in long-term treatment with opioids are an increase in continuous reaction time and subjective sedation score regardless of the routes of administration. Studies of drug addicts in long-term treatment with opioids seem to reflect a lowering of the general level of activity. According to recent studies, patients with chronic non-malignant pain conditions are responsible for the major part of the total opioid consumption. So far, no studies of cerebral dysfunction have been performed on this group of patients. Further research should concentrate on the use of few valid psychomotor and cognitive tests and should include patients with chronic non-malignant pain conditions.

[Long-term treatment with intrathecal morphine in severe painful cancer]. / Langtidsbehandling med morfin intratekalt ved svaere cancersmertetilstande.

Intrathecal treatment with morphine was instituted in seven cancer patients with severe pain. All of the patients had already received treatment with epidural morphine and the reason for the change in treatment was insufficient effect, side effects and/or pain connected with the injections in the epidural form of therapy. The duration of treatment was 5-136 days (median 40 days). The daily intrathecal dosage of morphine which was administered by 1-4 daily injections was initially 2.4-16.0 mg (median 3.6 mg) and had to be increased to 3.2-112 mg (median 16 mg) at the conclusion of treatment. Five patients became free from pain and one had acceptable relief of pain on this treatment. One patient received accidentally too great a dose of morphine intrathecally as compared with the usual dose and required treatment for respiratory insufficiency. Apart from postural headache on account of leakage of cerebro-spinal fluid, which could be treated by epidural blood "patch", the method was without complications which could be attributed to the intrathecally placed catheter. Treatment of pain with opioids injected intrathecally may thus be recommended in the cases in which epidural treatment cannot be carried out on account of the reasons mentioned above.

[Factitious disorder--an iatrogenic disease?]. / Uaegte sygdom--en iatrogen lidelse?

The case of a woman aged 31 years with numerous contacts with the health care system is reported. The patient presented an extremely varied pattern of complaints with pain as one of the most frequently recurring reasons for admission. During the past 12 to 13 years, the patient was admitted to inpatient units on numerous occasions and was submitted to numerous examinations, most of which revealed normal findings. This article lists a number of possible background causes which might permit a career like this to develop. Measures for prevention of similar "case-stories" in future are discussed.

[Morphine-induced hyperalgesia, allodynia and myoclonus--new side-effects of morphine?]. / Morfininduceret hyperalgesi, allodyni og myoklonus--nye morfinbivirkninger?

During the last ten years hyperalgesia (H), allodynia (A) and myoclonia (M) has been reported at an increased frequency in human beings treated with morphine. The side effects are most common in cancer patients treated with high dose morphine, and has been reported for all routes of administration. The mechanisms are unknown, but human cases and experimental works have resulted in the following theories: 1) Morphine and morphine metabolites change the postsynaptic pain-transmission in dorsal horn neurones via non opioid-receptors (glycine and/or N-methyl-D-aspartate). 2) Morphine and morphine metabolites activate other opioid receptor populations. 3) Supplemental drugs in cancer management. 4) An abnormal metabolism of morphine or morphine metabolites. 5) A combination of one or more of the above-mentioned theories. The first mentioned theory is the most likely. The treatment of morphine induced H, A, and M seems to be to discontinue morphine administration and to initiate therapy with other opioids (fentanyl, sufentanyl, methadone or ketobemidone).

[Transcutaneous nerve stimulation as palliative treatment of pain]. / Transkutan nervestimulation som smertepalliativum.

The value of transcutaneous nerve stimulation (TNS) for palliative relief of pain is reviewed. The presumed mechanisms of effect are briefly described and a review of recent literature concerning TNS for acute and chronic pain, respectively, is presented. In addition, advice is given for the choice of apparatus and the technique employed is described. It is concluded that TNS may be tried with advantage in the treatment of a number of acute and chronic painful conditions of neurogenic/nocioceptive nature and that TNS has the advantage over e.g. acupuncture that the patient can administer the treatment himself.

[Treatment of cancer pain in Denmark. A questionnaire survey]. / Behandling af cancersmerter i Danmark. En spørgeskemaundersøgelse.

A questionnaire survey was carried out with the aim of evaluating knowledge about and practice of cancer pain treatment in Denmark. A questionnaire was sent to a 10% random sample of Danish physicians. Of these 1411 physicians, 1068 (76%) returned the questionnaires and after the exclusion of those doctors who never treated cancer patients, 577 (54%) were analyzed. Their knowledge of the principles and practice of cancer pain treatment was evaluated by means of 14 multiple-choice and open questions. Their ability to apply their knowledge in practice was evaluated by analyzing their suggested treatment of three simulated patient cases. Ninety-seven percent of the physicians recognized difficulties in cancer pain treatment, the most frequent being side effects of drugs and inadequate pain relief. It appeared from the proposals for pain treatment of the patient cases that the majority of the physicians could treat both pain from bone metastasis (75%) and visceral pain (78%) satisfactorily, while very few suggested coanalgesics for neuropathic pain (20%). Older physicians performed less satisfactorily than did their younger colleagues. Basic pain treatment skills have been acquired by the Danish physicians. However, in the future emphasis should be placed on the treatment of neuropathic pain with coanalgesics and the management of opioid side-effects.
