RESUMO
BACKGROUND: In industrialized countries, chronic back pain is referred to as the "number one common disease". OBJECTIVES: Are there any indications of different outcomes of chronic back pain patients when treated with a multimodal, interdisciplinary pain therapy (MMSTh) compared to physiotherapy-physical therapy? MATERIALS AND METHODS: Entrance and final examination by means of survey, questionnaires and physical tests in the intervention and control group, evaluation and comparison of the results. RESULTS: The intervention group showed very significant improvements in all tests. In contrast, the control group achieved only partial improvements in physical parameters and quality of life. This resulted in clear group differences in favor of the MMSTh. In terms of patient satisfaction, the control group showed a better result than the intervention group. CONCLUSIONS: Treatment with MMSTh is superior to standard physiotherapy-physical. Due to the extensive, proven positive effect on many pain-causing and pain-preserving factors, multimodal pain centers should be used more frequently in chronic back pain patients.

BACKGROUND: Children and adolescents with severe hemophilia commonly suffer from acute and chronic pain as a consequence of hemophilia-related bleeding. Intervention-related pain also plays a major role. Despite its high prevalence in this patient group, hemophilia-related pain is not always adequately addressed and sufficiently treated. OBJECTIVES: This paper discusses how to improve pain management for children and adolescents (0-18 years) with hemophilia and which specific features in this population should influence decisions in pain management. MATERIALS AND METHODS: An expert panel discussed challenges in pain treatment in children and adolescents with hemophilia. Recommendations are based on evidence and clinical experience. RESULT: Pain management in children with hemophilia needs improvement. Children with hemophilia are at risk of developing chronic pain and of suffering traumatization due to insufficient pain management. Pain therapy can be challenging in these children as both their age and the underlying disease limit the options in particular in pain medication. The expert panel developed recommendations to improve pain management in children with hemophilia.

RESUMO
BACKGROUND: Pain after surgery, especially on the first postoperative day, results in longer hospital stays, increased complication rates and may also cause a higher risk of pain chronification. However, the expected intensity of pain is often misjudged and therefore not adequately treated. METHODOLOGY: An Austria-wide patient survey on the pain situation on the first postoperative day and on the quality of perioperative pain management was carried out on a voluntary and anonymous basis. RESULTS: Regarding the intensity of pain a clear gender difference could be observed. Women were more prone to more severe pain than men across all age groups. This difference was most pronounced in the younger age groups (18-40 years) and in those patients showing the highest pain scores. Treatment satisfaction was correlated (high significance) with pain intensity on exercise (pâ¯< 0.01), maximum pain (pâ¯< 0.01), least pain (<0.01) and frequency of postoperative pain assessment. DISCUSSION: The risk of postoperative pain can be reduced by optimal care structures. Since patients treated in optimal care structures had significantly lower pain scores on exercise and with respect to maximum pain, the investment in the optimization of such resources should be carefully planned. Special attention should be paid to postoperative pain management in women, especially in younger female patients.

BACKGROUND: The success of radiofrequency ablation (RF) of the medial branch of the dorsal ramus in patients with facet joint pain depends on the effective coagulation distance. To date, computed tomography(CT)-guided techniques do not reach the nerve in parallel but rather than punctually. We report a new CT-guided technique to enhance parallelism and proximity of the RF needle to the nerve. MATERIALS AND METHODS: Two examiners with different experience with CT-guided procedures in corpses performed all punctures at the lumbar spine on 10 corpses. A RF needle was inserted 1â¯cm lateral to the spinous process of the vertebra located caudal to the target nerve. The needle was advanced under CT guidance at a flat angle between the superior articular process and the base of the costal or transverse process of the cranial vertebra. The position was verified by dissection. Needle position was judged successful provided the needle could be positioned in the first attempt with no more than one angle correction. RESULTS: In 86 out of 100 possible cases (50 per side) at the 5 lumbar segments, the RF needle could be depicted by CT in the target area with no more than one correction of the needle position. Anatomical dissections revealed that 47 out of 86 needles (54.6%) fulfilled the requirements of parallelism and proximity to the nerve. The dorsal ramus was never reached by the RF needle. Higher success rates were obtained in the middle segments compared to the border segments of L1-L2 and L5-S1. CONCLUSIONS: We could demonstrate that the principle of parallelism and proximity of the needle to the nerve could be fulfilled with this new technique; however, needle positioning requires practice due to the oblique puncture direction.

For improvements in exercise tolerance and cognitive function in geriatric patients Multimodal training programs (MTP) are used as combination of physiotherapy, occupational therapy and cardiovascular training. Intermittent Hypoxic-Hyperoxic Training (IHHT), a modified type of intermittent hypoxic training (IHT) is proposed to be included in MTP to elicit more pronounced beneficial effects in exercise tolerance and cognitive functions of geriatric patients likely by an additional pathway than a single MTP. Thirty four patients of the Geriatric Day Clinic aged between 64 and 92 years participated in the placebo controlled clinical trial. They were randomly assigned to receive MTP plus IHHT (experimental group - EG) or MTP plus placebo-breathing through a machine face mask (control group - CG) in a double blind fashion. Before and after the interventions course cognitive performance was assessed by the Dementia-Detection-Test (DemTect) and the Clock-Drawing-Test (CDT), and functional exercise capacity - by the total distance of 6-Minute-Walk-Test (6MWT). After IHHT combined with MTP cognitive performance (DemTect) increased significantly when compared to NG (+16,7 % vs. +0,39 %, p<0,001). The CDT indicated similar results with a significant increase in the EG while the score of the CG even decreased (+10,7 % vs. -8%, p=0,031). Concerning the functional exercise capacity, both groups improved the total distance in the 6MWT but with a significantly larger increase in the EG compared to the CG (+24,1 % vs. +10,8 %, p=0,021). In addition, there was a significant relationship between the changes of the 6MWT and the DemTect Scores and the CDT. IHHT contributed significantly to improvements in cognitive performance and exercise capacity in elderly performing MTP. IHHT sessions are considered to be easily applicable to and well tolerated by geriatric patients up to 92 years.

Despite many positive developments, postoperative pain and its treatment is still not always given the necessary attention. Severe pain after surgical procedures affects a significant proportion of patients. This very fact is not only detrimental to the immediate recovery process, but can also form the basis for the development of chronic pain conditions.An adequate and effective management of perioperative pain requires appropriate organizational structures. This multidisciplinary paper which was initiated by the Austrian Society for Anaesthesiology and Intensive Care and the Austrian Pain Society and developed together with numerous specialist and professional societies dealing with the subject aims at supporting the organization of perioperative pain management structures and to make best use of proven concepts. Additional recommendations describe specific interventions for selected types of intervention.

BACKGROUND: Nursing homes are confronted more and more with palliative care patients, which present a challenge for nursing and medical personnel. Deficits in the palliative care of geriatric patients have been repeatedly demonstrated and many nursing home residents, especially those suffering from dementia, are undersupplied regarding pain management. OBJECTIVES: The present study was carried out to measure the knowledge and self-efficacy of nursing staff in the province of Carinthia (Austria) regarding palliative care of nursing home residents. MATERIAL AND METHODS: A total of 330 nursing personnel were surveyed using the Bonn test for knowledge in palliative care (BPW), which measures knowledge and self-efficacy in nursing home personnel. In addition to descriptive analyses, the effects of the professional group (registered nurses vs. nursing assistants) and working experience were tested. RESULTS: On average a little more than half of the knowledge items were answered correctly. Nurses' self-efficacy was high. Registered nurses exhibited more knowledge and higher self-efficacy compared to nursing assistants. Effects of working experience could only be demonstrated regarding self-efficacy. CONCLUSION: The results are to a large extent in line with results from Germany and indicate the necessity of interventions for improving nurses' knowledge as a major basis for adequate palliative care in nursing home residents.

Objective: For radiofrequency neurotomy of the medial branch of the lumbar dorsal rami, physicians use techniques guided either by fluoroscopy or computerized tomography (CT), and advocate for their respective techniques. Crucial to the choice of technique is how well each can capture the target nerve. The present study was, therefore, undertaken to assess in cadavers the accuracy of fluoroscopic-guided and CT-guided techniques. Design: In10 cadavers preserved with Thiel's method, electrodes with 10mm active tips were placed in supine position on the right using a fluoroscopic-guided technique, and on the left using a CT-guided technique. Using a special dissection approach, the relationship between the target nerve and the tip of the electrode was revealed. The displacement between electrode and the nerve, and the extent to which the electrode was parallel to the nerve, were measured with callipers. Results: Under fluoroscopy guidance, electrodes were placed accurately beside the nerve, and were parallel to it for 9 ±1.9 mm. In only two cases did the electrode pass too deeply. Under CT guidance, electrodes often failed to reach the nerve, but when they did they were parallel to it for only 3.2 ± 3.2 mm. In seven cases, the electrode passed too deeply beyond the target nerve. Conclusion: The fluoroscopy-guided technique can be relied upon to achieve optimal placement of electrodes on the lumbar medial branches. The CT-guided technique fails to do so, and should not be used in practice until a modified version has been developed and validated.

BACKGROUND: In a survey of all adult inpatients at the Wilhelminen Hospital in Vienna and the Klagenfurt Clinic on Lake Wörthersee, data on pain prevalence, the most frequent sites of pain, pain intensity, pain type, effect of pain on patients, pain evaluation on the various wards, pain precipitating factors, and patient satisfaction were collected. MATERIALS AND METHODS: All inpatients > 18 years were questioned using a questionnaire developed by the investigators at the Department for Anesthesia, Intensive Care, and Pain Medicine at the Wilhelminen Hospital. RESULTS: A pain prevalence of 45.7% was found at the Wilhelminen Hospital and of 40.8% at the Klagenfurt Clinic. Women reported pain significantly more often than men. No significant difference was found between surgical and conservative treatment wards in terms of pain prevalence. Patients on conservative treatment wards reported significantly higher current pain intensity than those in surgical departments. The most common areas of pain were joints and bones. A score >3 in the ID pain questionnaire was reached by 8.8% (Wilhelminen Hospital) and 4.0% (Klagenfurt Clinic) of participants. Pain influenced mood, mobility, and nighttime sleep, and was intensified by the daily clinical routine. CONCLUSION: Overall, it was demonstrated that the majority of patients at both hospitals were satisfied with the pain management. However, pain management in conservative treatment disciplines must not be neglected. More intense current pain, a worse quality of life, and a trend toward lower patient satisfaction indicate that analgesic treatment in nonsurgical disciplines should be optimized.

BACKGROUND: Until recently the measurement of pain in cognitively impaired patients represented a neglected field in the diagnostics and treatment of pain. Investigations indicate a prevalence of pain in nursing home residents of between 45 % and 80 %. MATERIAL AND METHODS: This study investigated the reliability of the German translation of the Doloshort scale and compared it with the visual analog scale (VS). The aim of this study was to determine the practical applicability of this scale in the clinical routine and to calculate the intrarater reliability (retest) and interrater reliability. RESULTS: The interrater and intrarater reliability of the Doloshort scale was between 0.949 and 0.970. There was a highly significant correlation between the values of the Doloshort scale and the VAS. CONCLUSION: The Doloshort scale is a well suited measurement instrument for the evaluation of pain in cognitively impaired patients. Because of the short form only simple instructions are necessary and it has a high acceptance with users.

Metamizole (dipyrone) is a nonsteroidal compound with strong analgesic as well as antipyretic and spasmolytic properties. Based on a small number of cases of agranulocytosis, metamizole was withdrawn from the market in some countries. Other countries restricted its use. This paper discusses the safety aspects of metamizole and compares it with other compounds used for similar indications.

BACKGROUND: Interference with the function of the genitofemoral nerve (GFN) and lateral femoral cutaneous nerve (LFCN) represents a significant complication of lumbar sympathetic blocks (LSBs). The nerve topography of the lumbar sympathetic trunk (LST) was investigated to find a possible morphological reason for this. METHODS: A total of 118 cadavers embalmed by Thiel's method were investigated. The nerves were dissected from their innervation area to their paravertebral origins. Distances of the GFN and the LFCN to the LST were measured at levels L2/3, L3/4, and L4/5, which are the most common levels for LSB. RESULTS: Two hundred and thirteen sides were assessable for the GFN and 151 sides for the LFCN. In 186 cases, the whole GFN (in 20 cases, its femoral branch only) approached the medial margin of the psoas major (PM) and passed the LST laterally at the level of L3/4 and a distance of 0-28 mm (mean distance 8.5 mm; sd 6.7 mm) and ran dorsally between the PM and the vertebral body of L3, reaching the intervertebral foramen L2/3. In three cases, the GFN fused with the LFCN. In 55 cases, the GFN-LST distance was 0-13 mm at L4/5 and in 19 cases, 9-19 mm at L2/3. The LFCN approached the lateral margin of the PM and entered the intervertebral foramen at L2/3 in 141 cases. CONCLUSIONS: There is a higher risk of LSB affecting the GFN at L3/4 or L4/5 during neurolysis of the LST due to its topography. The LFCN rarely shows a strong relation to the LST and only when fused with the GFN.

BACKGROUND: We evaluated a vertical obturator nerve block (VOB) using a single morphological landmark and no additional distance measurement or obligatory changes of the needle's direction. MATERIALS AND METHOD: A total of 88 cadavers (176 lower limbs), prepared using Thiel's embalming method, were examined. The index finger was placed lateral to the palpable pubic tubercle and the needle inserted laterally to the distal part of the fingernail at the tubercle's level and advanced strictly perpendicular to the table's surface. If bone contact was made, the needle was slightly turned to pass the bone distally. Colored latex (5 ml) was then injected. The injection depth was documented, then followed by dissection and nerve exposition. The real skin-nerve distance and the degree of difficulty in orientation and of palpation were measured. Additionally, the dissemination around the nerve or its branches and the intrapelvic spread were documented. RESULTS: The nerve was colored completely in 93.75%, partially in 1.71%, and not colored in 4.54% of cases. The mean injection depth was 3.9 cm (±0.7 SD) and real nerve depth was 3.8 cm (±0.69 SD). Bone contact necessitating the needle's redirection was found in 20 (11.4%) cases. Easy orientation and palpation of the tubercle was always found. In 40 cases, the latex spread via the obturator canal into the lesser pelvis. CONCLUSION: In this anatomical study, the VOB technique exhibits easy orientation without stimulation or ultrasound guidance. The nerve was located at a constant depth. The injection offered a high percentage of colored nerves.

BACKGROUND: Despite increasingly sophisticated concepts of perioperative pain therapy, such as increased use of combined regional anesthesia techniques, the renaissance of ketamine and dipyrone or the use of oral opioids, no significant improvement has been achieved in postoperative pain therapy since 1995. About 300,000 of the approximately 700,000 patients undergoing major surgery each year in Austria experience moderate to severe postoperative pain. The aim of this study was therefore to assess the nationwide status of perioperative acute pain management in postoperative recovery rooms and surgical wards in order to identify potential areas for improvement. METHODS: In 2006 the directors of all Austrian anesthesiology departments (n=125, 100%) were contacted and asked to give detailed information on the status of acute pain management of each individual hospital in Austria using a standardized questionnaire. Data of each individual department were derived from quality control and self-assessment of each department. No patients were questioned. The return rate was 96% (n=120) due to intensive personal contact in cases of missing data. RESULTS: In this nationwide survey 120 anesthesiology departments participated together accounting for a total of 757,895 operations per year. Of the patients 63.6% were informed preoperatively on the available regimens of acute pain management. In 81% of patients perioperative pain therapy consisted of a multimodal therapeutic approach, 58.6% of the departments used international guidelines and 39.7% worked with international guidelines adapted to local requirements. In 88% of patients a detailed prescription for postoperative pain therapy was available when transferred to the surgical ward. Surgical wards were equipped with routine pain therapy protocols in 28% another 20% of wards had special pain therapy protocols for individual operations. In 22% of cases pain assessment was repeated 3-4 times per day and in 33.9% postoperative pain was assessed only once twice per day. Pain assessments were recorded in the patient charts in 60.7% of cases. If changes to the pain therapy regimen were required anesthesiologists were involved in only 14.3% of cases. In addition an acute pain service was available only in 39.2% of Austrian anesthesiology departments. CONCLUSIONS: Although the multimodal approach to acute pain therapy is widely used and standardized therapeutic regimens are well established in the majority of anesthesiology and surgical wards, there still remains room for improvement. Pain assessment is generally barely adequate and written documentation of pain assessment is missing almost completely. In addition, almost two thirds of hospitals in Austria are still lacking an acute pain service.

BACKGROUND: The primary aim of this study was to determine whether the combination of i.v. ketoprofen and i.v. paracetamol provides superior postoperative analgesia in children undergoing adenoidectomy or tonsillotomy compared to either drug alone. The secondary goal was to assess the time until rescue analgesia was needed, propofol requirements and the incidence of vomiting and time of discharge from the postanaesthesia recovery unit (PARU). METHODS: This double-blinded study included 120 children (aged 3-13 years) scheduled for elective tonsillectomy, adenoidectomy or adenotonsillectomy. The children were randomly assigned to one of 3 groups of 40 children each, using the sealed envelope method. The children received i.v. ketoprofen 2 mg/kgBW (group 1) or paracetamol 15 mg/kgBW (group 2) or the combination of these 2 drugs (group 3) after induction of anaesthesia. Standardized general anaesthesia consisted of sevoflurane and fentanyl at a dose of 2-3 µg/kgBW. Pain was assessed using a 5-point scoring system based on the Smiley scale. The Smiley scale shows various faces from a laughing face which corresponds to the state of no pain to a very unhappy face which corresponds to the situation of worst pain (1: no pain, 2: mild pain, 3: moderate pain, 4: severe pain, 5: worst pain). Pain was assessed at 30 min, 1 h, 2 h, 3 h and 4 h after arriving in the PACU. If the pain score exceeded 2 an i.v. dose of 0.1 mg/kgBW morphine was administered as rescue analgesia. RESULTS: During the stay in the PACU the children in the combination group required significantly less supplementary rescue analgesia than children in the ketoprofen and paracetamol groups (17.5% versus 30.8% versus 45%, respectively, χ(2) analysis <0.05). Pain scoring was highest after paracetamol, however, this difference was only significant when compared to the group receiving the combination of paracetamol and ketoprofen (U-test p<0.05). Rescue analgesia was administered earliest in group 2 (paracetamol) reaching statistical significance, however, only when compared to group 3 (logrank test p<0.05). Propofol requirements and time to discharge from the PACU did not differ significantly between the 3 groups (χ(2) analysis; U-test; p>0.05). The overall incidence of vomiting was very low in this study with 6.4% (9/139). Significantly more children in the paracetamol group compared to ketoprofen group and combination group suffered from vomiting (17.5% versus 2.6% versus 2.5%; χ(2) analysis; p<0.05). The time to discharge from PACU did not differ significantly between the 3 groups (U-test: p>0.05). CONCLUSION: The combination of i.v. paracetamol and i.v. ketoprofen provides superior postoperative analgesia compared to the single use of paracetamol.

BACKGROUND: In the postoperative period, α2-adrenergic agonists have an opioid sparing effect. In a previous, experimental study, it was also shown that clonidine attenuates remifentanil-induced hyperalgesia. In this study, we examined under clinical conditions whether early administration of a single dose of clonidine can inhibit remifentanil-induced hyperalgesia in patients undergoing elective surgery of the shoulder and with continuous intraoperative use of remifentanil. PATIENTS AND METHODS: In this study 40 patients received double-blind and randomized either 150 µg clonidine or placebo intravenously before skin incision. Anaesthesia was maintained with propofol and remifentanil (0.23 ± 0.09 µg/kg body weight/min) and morphine (0.1 mg/kg body weight) was administered 20 min before incision closure. Postoperatively, the patients were given a patient-controlled analgesia pump (PCA) with morphine. RESULTS: Overall morphine consumption as well as overall assessment of pain with the visual analogue scale in the first 24 h postoperatively did not differ significantly between the groups. Isolated pain scores at 12 h and 24 h were significantly enhanced in the clonidine group (p<0.05). CONCLUSION: An early single dose of 150 µg of clonidine did not reduce the postoperative morphine consumption and pain scores in patients undergoing elective surgery of the shoulder with remifentanil/propofol-based anaesthesia. After the effect of clonidine has presumably subsided the pain can even increase, therefore further studies with repetitive doses of clonidine should be carried out.

BACKGROUND: During ultrasound (US)-guided cannulation of the subclavian vein (SCV) via an infraclavicular route, the view of the needle behind the clavicle may be obscured. This study describes the US-guided supraclavicular cannulation of the brachiocephalic vein (BCV). METHODS: The 25 mm broadband linear array US probe was placed in the supraclavicular region to obtain a longitudinal view of the BCV beginning at the junction of the internal jugular vein and SCV. Using the in-plane technique, the needle was directed under US guidance into the BCV. RESULTS: Forty-two cannulations in 35 patients (aged 26 months-8 yr, weight range 0.96-21 kg) were included. Central venous catheter placement was successful in all children. In 31 patients (73.8%), the BCV was successfully punctured on the first attempt, in six patients (14.2%) after two attempts, and in five patients (11.9%) after three attempts. Significantly more puncture attempts were needed in the smaller weight and younger children, whereas the time course of the study had no significant impact on the success rate. CONCLUSIONS: This US-guided method offers a new possibility for central venous line placement in small children. It provides good needle guidance without any disturbing US shadow caused by bony structures.

BACKGROUND: Degenerative processes of the lumbar spine may change the position of the sympathetic trunk which might cause failure of sympathetic blocks owing to inadequate distribution of local anaesthetic. METHODS: The retroperitoneal spaces of 56 cadavers [24 males and 32 females; 79 (10) yr] embalmed with Thiel's method were investigated by dissection. The course of the lumbar sympathetic trunk (LST) was documented from the diaphragmatic level to the linea terminalis. Topography of the large vessels and the psoas muscle was documented. In the case of spondylophytes, the location or direction of displacement of the trunk was regarded with special interest. RESULTS: The LST entered the retroperitoneal space at the level of the vertebral body of L2 in 70 of the 112 sides and showed the most consistent relationship with the medial margin of the psoas muscle at intervertebral disc level L2/3. On 11 spines with spondylophytes, the sympathetic trunk was dislocated to the most ventrolateral point of the spondylophyte in 12 cases, in six cases dorsolaterally, and in one case ventromedially. The more the sympathetic chain departed at the vertebral body level, the more the body developed a concavity by loss of height. CONCLUSIONS: Spondylophytes influenced the location of the LST and the distribution of the local anaesthetic. The local anaesthetic should wash around the spondylophyte to reach all possible locations of the chain. The medial margin of the psoas muscle was confirmed to be a consistent reference point at intervertebral disc level L2/3.

BACKGROUND: The goal of the study was to substantiate the influence of TENS on pain development and medication needs of patients with proven gonarthrosis and chronic pain. The study included a 3-week stimulation period and 2-week observation period after the end of stimulation. MATERIALS AND METHODS: Patients (at least 20 per group) were assigned to either an active treatment group or placebo group in a randomised, double-blind, placebo-controlled trial. For the active treatment group the TENS therapy device with HAN stimulation (alternating phase of stimulation) was used (TENStem eco).Total length of time: 30 min at least two times a day. The length of therapy was 3 weeks (therapy), followed by an observation period of 2 weeks (follow-up). The total length of the study was 5 weeks, whereby at the beginning and at the end of weeks 1, 3 and 5 the SF-36, WOMAC score and Lysholm score were documented; the pain score was documented daily. RESULTS: There are no significant demographic differences between the groups. In the active treatment group there was clear relief in pain intensity in the morning, midday and evening over the 3-week period of therapy. The Lysholm score in the active treatment group was 53.4 at the beginning, 90 after 1 week, 94.5 after the third week and 91 by the fifth week (significant difference). There were no side effects. CONCLUSION: TENS therapy with HAN stimulation resulted in pain relief in patients with gonarthrosis during the therapy period with TENS, but the pain relief did not last beyond the end of the TENS therapy. There was an improvement in the Lysholm score and the WOMAC score during the therapy. This improvement remained over the following 2-week period of observation without further TENS therapy. TENS therapy is a simple and effective method to treat gonarthrosis with very few side effects.
