- Clinical outcomes after major surgery are poorly described at the national level. Evidence of heterogeneity between hospitals and health-care systems suggests potential to improve care for patients but this potential remains unconfirmed. The European Surgical Outcomes Study was an international study designed to assess outcomes after non-cardiac surgery in Europe.

- This randomized, cross-over, double-blind, controlled study of continuous intrathecal morphine administration in patients with severe, long-term pain addresses whether the supplementation of low doses of naloxone in this setting is associated with beneficial clinical effects. All of the study subjects (n=11) provided informed consent and were recruited from a subset of patients who were already undergoing long-term treatment with continuous intrathecal morphine because of difficult-to-treat pain. The patients were (in a randomized order) also given intrathecal naloxone (40 ng/24 h or 400 ng/24 h). As control, the patients' ordinary dose of morphine without any additions was used. The pain (Numeric Rating Scale, NRS) during activity, perceived quality of sleep, level of activity and quality of life as well as the levels of several pro- and anti-inflammatory cytokines in the blood were assessed. The pre-study pain (NRS during activity) in the study group ranged from 3 to 10. 64% of the subjects reported improved quality of sleep during treatment with naloxone at a dose of 40 ng/24 hours compared with 9% with sham treatment (P=0.024). Although not statistically significant, pain was reduced by 2 NRS steps or more during supplemental treatment with naloxone in 36% of subjects when using the 40 ng/24 hours dose and in 18% of the subjects when using a naloxone 400 ng/24 hours dose. The corresponding percentage among patients receiving unaltered treatment was 27%. To conclude, the addition of an ultralow dose of intrathecal naloxone (40 ng/24 h) to intrathecal morphine infusion in patients with severe, persistent pain improves perceived quality of sleep. We were not able to show any statistically significant effects of naloxone on pain relief, level of activity or quality of life.This is an open-access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivitives 3.0 License, where it is permissible to download and share the work provided it is properly cited.

- OBJECTIVES: Police officers are at high risk of being exposed to psychologically straining situations and potentially psychotraumatic experiences. In this article, such situations are exemplified and categorized, and the role and significance of secondary prevention following traumatic experiences is discussed. METHODS: From 1994 to 2003, 649 police officers received secondary prevention after being involved in a total of 250 potentially traumatic or psychologically stressful incidents. Psychological support was provided by teams of specially trained professionals in the acute phase after the incident following careful psychological evaluation. In a retrospective evaluation, the diagnoses obtained were analyzed with regard to sex and age and correlated with the severity of the incident. Three clusters of potentially traumatic situations were formed: (1) Employment of fire-arms with danger for the officer, (2) Standard situations including violence towards a third party, (3) Suicide or attempted suicide of a police officer. RESULTS: Police officers who experienced events assigned to cluster (1), comprising situations with considerable traumatic potential, had the highest incidence of posttraumatic stress disorder (PTSD) or other mental illness. Compared to male officers, females were more often diagnosed with other mental illness, whereas males had a higher incidence of PTSD. Cluster (2), which comprised situations of an officer's daily professional life, was not associated with an increased risk of mental illness. Officers were apparently capable of coping with situations considered psychologically straining for the general public without detectable evidence of a traumatic reaction. In cluster (3), which reflects the most dramatic interference with team relations, other forms of mental illness were diagnosed at a higher incidence.

- Sepsis-associated myocardial depression is associated with calcium desensitization and adrenergic uncoupling. We conducted a prospective randomized investigation on the effects of the calcium sensitizer, levosimendan, on hemodynamics, myocardial blood flow, and myocardial lactate metabolism during porcine endotoxemia. Twelve pigs were studied. Oxygen consumption was measured by indirect calorimetry, and myocardial blood flow was measured by retrograde thermodilution. Pulmonary, arterial, and venous indwelling catheters allowed measurements of cardiac output, vascular pressures, and blood sampling. Fluids were given at an average of 15 mL . kg . h. After baseline measurements (0 min), an infusion of Escherichia coli LPS (2 microg . kg . min) was started in all animals. Beginning at 100 min, six animals received levosimendan (50 microg . kg . h), whereas six control animals received placebo. The study lasted for 300 min. All animals responded to endotoxin with pulmonary hypertension, a transient decrease in cardiac output, tachycardia, and systemic hypotension. Levosimendan infusion decreased systemic vascular resistance (P = 0.001), coronary vascular resistance (P = 0.004), and mean arterial (P < 0.001) and coronary perfusion pressures (P < 0.001), whereas pulmonary hypertension was unaffected. Heart rate progressively increased in both groups and was significantly higher in the levosimendan group (P = 0.048). Myocardial blood flow remained unchanged in both groups; however, 80 min after the start of levosimendan infusion, left ventricular myocardial hypoxia ensued, as evidenced by a negative myocardial lactate gradient (P = 0.01). Two control and five levosimendan animals died before the end of the study. Early administration of levosimendan during porcine endotoxemia increased heart rate, caused arterial vasodilation, and decreased coronary perfusion pressure, resulting in myocardial hypoxia.

- BACKGROUND: Severe pain in the head and neck is associated with a lowered quality of life and conventional pain therapy often does not provide adequate relief. The aims of this study were to investigate the efficacy, pain relief, benefits and adverse effects of intracisternal or high cervical (IHC) administration of bupivacaine in patients with severe pain in the head, neck and face regions. METHODS: Between 1990 and 2005, 40 patients (age 27-84 years) were treated with continuous IHC infusions of bupivacaine for various non-cancer (n=15) or cancer-related (n=25) refractory pain conditions (duration 1 month-18 years) in the head, neck, mouth and shoulder regions. RESULTS: Visual analogue scale scores and opioid requirements decreased markedly after the start of the treatment and remained lowered throughout the study. No tachyphylaxis for bupivacaine was observed. Major side effects were few and most often transient. Most patients showed unchanged or improved mobility. There was no mortality, neurological damage or other severe events attributable to procedures in the study protocol. CONCLUSION: For patients with severe and refractory pain in areas innervated by cranial and upper cervical nerves, cervical high spinal analgesia can provide safe and effective analgesia.

Surgical treatments for postamputation pain: study protocol for an international, double-blind, randomised controlled trial

- BACKGROUND: Painful conditions such as residual limb pain (RLP) and phantom limb pain (PLP) can manifest after amputation. The mechanisms underlying such postamputation pains are diverse and should be addressed accordingly. Different surgical treatment methods have shown potential for alleviating RLP due to neuroma formation - commonly known as neuroma pain - and to a lesser degree PLP. Two reconstructive surgical interventions, namely targeted muscle reinnervation (TMR) and regenerative peripheral nerve interface (RPNI), are gaining popularity in postamputation pain treatment with promising results. However, these two methods have not been directly compared in a randomised controlled trial (RCT). Here, we present a study protocol for an international, double-blind, RCT to assess the effectiveness of TMR, RPNI, and a non-reconstructive procedure called neuroma transposition (active control) in alleviating RLP, neuroma pain, and PLP. METHODS: One hundred ten upper and lower limb amputees suffering from RLP will be recruited and assigned randomly to one of the surgical interventions (TMR, RPNI, or neuroma transposition) in an equal allocation ratio. Complete evaluations will be performed during a baseline period prior to the surgical intervention, and follow-ups will be conducted in short term (1, 3, 6, and 12 months post-surgery) and in long term (2 and 4 years post-surgery). After the 12-month follow-up, the study will be unblinded for the evaluator and the participants. If the participant is unsatisfied with the outcome of the treatment at that time, further treatment including one of the other procedures will be discussed in consultation with the clinical investigator at that site. DISCUSSION: A double-blind RCT is necessary for the establishment of evidence-based procedures, hence the motivation for this work. In addition, studies on pain are challenging due to the subjectivity of the experience and the lack of objective evaluation methods. Here, we mitigate this problem by including different pain evaluation methods known to have clinical relevance. We plan to analyse the primary variable, mean change in NRS (0-10) between baseline and the 12-month follow-up, using the intention-to-treat (ITT) approach to minimise bias and keep the advantage of randomisation. The secondary outcomes will be analysed on both ITT and per-protocol (PP). An adherence protocol (PP population) analysis will be used for estimating a more realistic effect of treatment.
