Caudal Block versus Wound Infiltration for Inguinal Procedures in Young Children: A Randomized Clinical Study.

INTRODUCTION: Inguinal procedures in children are frequent and typically performed in an outpatient setting. We aimed to analyze whether there is a difference in postoperative pain scores and setup time (start of anesthesia management to incision time) when comparing caudal block (CB) with local wound infiltration. MATERIALS AND METHODS: We enrolled pediatric outpatients scheduled for inguinal procedures. Patients were randomized to receive either preincision CBs or end-of-procedure local wound infiltration. Postoperative pain scores until 24 hours postoperatively and setup time were analyzed. RESULTS: Fifty-two patients were included in the study. Thirty patients received a CB, and 22 patients received local infiltration (LI). There was no significant difference in postoperative pain scores. Setup time was significantly higher in the CB group: median 22.5 minutes IQR (16-46 minutes) compared with 17 minutes in the LI group IQR (10-35 minutes), p-value of 0.0026. CONCLUSION: Both CB and LI result in good postoperative pain control after inguinal procedures in pediatric outpatients. Since LI is less time consuming and has lower risks for complications, we recommend this technique for inguinal procedures in pediatric outpatients. Our findings will need to be confirmed in larger cohorts, but we believe the evidence generated with this study has the potential to positively influence patient care, operating room efficiency, and costs.

Mental disorders are no predictors to determine the duration of cannabis-based treatment for chronic pain.

Background: Chronic pain (CP), a complex biopsychosocial disorder with a global prevalence of up to 33%, can be treated by following multidisciplinary approaches that may include cannabis-based medicine (CBM). However, because CBM continues to be a new treatment, questions remain regarding the ideal duration for CBM and its psychosocial determinants, including mental comorbidities. Methods: In a retrospective cross-sectional study involving 46 patients with CP (ICD-10 code F45.4-), three validated instruments-the German Pain Questionnaire, the Depression Anxiety Stress Scale (DASS), and the Marburg Questionnaire of Habitual WellBeing-were used to identify pain-specific psychosocial determinants and mental disorders. Descriptive analyses, a group differences analysis, and a logistic regression analysis were performed using SPSS. Results: The patients most frequently reported low back pain as the primary location of their CP, and in attributing the condition to tissue damage, most had largely adopted a somatic orientation in conceptualizing their illness. Most had experienced CP for more than 5 years (M = 5.13 years, SD = 1.41) and, as a consequence, faced significant restrictions in their everyday life and exhibited low subjective wellbeing (MFHW median = 4.00, N = 43, Q1: 2.00, Q3: 9.00, range: 0-20). Comorbidities among the patients included depression, (DASS-Depression, median: 11.50, Q1: 7.00, Q3: 16.25), anxiety (DASS-Anxiety, median: 4.50, Q1: 2.75, Q3: 8.00), and stress (DASS-Stress, median: 11.00, Q1: 7.00, Q3: 15.00). Between the two cannabis-based treatments with a course lasting either less or more than a year, the duration of treatment showed no between-group differences in terms of sociodemographic factors, pain-specific factors, conceptualizations of the illness, or mental disorders. Psychosocial determinants such as subjective wellbeing and mental comorbidities were not significant predictors of the duration of cannabis-based treatment. Conclusion: We found no evidence indicating that the benefits of short-term vs. long-term cannabis-based treatment can be predicted by mental comorbidities or psychosocial factors. However, because CBM may be included in approaches to treat CP, questions about the ideal duration of such treatment remain to be answered.

Teaching about chronic pain in psychosomatics courses - an overview of the situation in Germany and the Tübingen Model Objectives: When dealing with chronic pain patients it is crucial to take a bio-psycho-social approach. However, it is unclear how this approach is currently being taught to medical students, and how they judge its role and importance. METHODS: We carried out a qualitative study (questionnaire) asking (1) German psychosomatic departments about pain-related teaching and (2) medical undergraduates about pain-relevant issues. RESULTS: Bio-psycho-social facts are well represented within psychosomatics courses but only theoretically tested. There is still much room for improvement through cross-linking with other disciplines. In Tübingen, "psychosocial factors" and the "empathic doctor-patient relationship" play a significantly higher role when teaching psychosomatic courses than somatic ones. There were no significant differences regarding the role of an "integrative recording of medical history" or how the importance of any of the three topics was rated. CONCLUSIONS: Chronic pain is well represented in psychosomatic courses in Germany, though exams could be more practical. The establishment of interdisciplinary approaches beyond the teaching of core psychosomatic content could be expanded and especially used more frequently when adapting curricula to competence-based standards.

Perioperative epidural analgesia in children undergoing major abdominal tumor surgery--a single center experience.

PURPOSE: The purpose of this study was to assess the use of continuous epidural analgesia in pediatric patients undergoing major abdominal tumor surgery. METHODS: Children undergoing major abdominal tumor surgery at our institution between 2008 and 2012 (n=40) received continuous epidural analgesia via an epidural catheter. Surgical trauma scores, pain scores, and clinical data of the children were compared to a pair-matched historical control group operated on between 2002 and 2007 without epidural analgesia. RESULTS: Pain levels in the study group on day 1 and 3 after surgery were lower compared to the control group. The differences did, however, not reach statistical significance (p=0.15 and 0.09). Children in the study group received significantly fewer additional doses of piritramide or morphine (45% versus 82%, p<0.001). Despite significantly higher surgical trauma scores in the study group (p=0.018), there were no statistical differences regarding clinical parameters, such as mechanical ventilation time, time on intensive care unit, and total hospital stay. There were no catheter-related complications. CONCLUSIONS: Continuous epidural analgesia is beneficial for children undergoing complex abdominal tumor surgery with regard to pain levels, postoperative recovery, and general clinical course. Expertise of the managing team, a careful patient selection, and a continuous quality assessment are essential for success.

No patient needs to have pain? Providing the best possible pain relief is as challenging for the anaesthesiologist as it is necessary for the patient's quality of life. The WHO algorithm allows sufficient and satisfactory treatment of 90 % of all cancer patients. This case report describes alternatives to the WHO algorithm for the remaining 10 % of cases. The alternatives concern opioid rotation, intravenous administration, and neuroaxial application. Indications for these alternative strategies are either opiod-insensitive incidental pain or neuropathic pain. Procedure and complications are discussed with the reader.
