COVID-19パンデミックが慢性疼痛患者の痛みの強さ、心理状態、運動習慣に与えた短期間での影響

Purpose: The coronavirus disease 2019 (COVID-19) pandemic has affected the lives of people worldwide. The first declaration of a state of emergency in Japan, based on the Act on Special Measures for the Prevention and Control of the Novel Coronavirus, was issued from 16 April 2020 to 14 May 2020 to reduce person-to-person contact. Restrictions on going out, participating in community activities, and visiting hospitals were in place. This study investigates the short-term effects of the COVID-19 pandemic on patients with chronic pain. Methods: This study included outpatients with chronic pain undergoing treatment at the Pain Center of Nara Medical University Hospital. The patients had completed questionnaires for a disability during the study period, from 1 July to 30 September 2019 (baseline), 1 October to 31 December 2019 (pre-pandemic), and 1 July to 30 September 2020 (during the pandemic). The questionnaire covered changes in disability, pain intensity, health-related quality of life (QOL), anxiety, depression, catastrophic thinking, and the presence/absence of exercise habits at baseline, pre-pandemic, and during the pandemic. Results: Of the 245 eligible patients, there was no significant disability difference between baseline, pre-pandemic, and during the pandemic (p = 0.14). Similarly, pain intensity, health-related QOL, anxiety, depression, and the presence/absence of exercise habits did not significantly differ between baseline, pre-pandemic, and during the pandemic either. The current study observed significant differences in terms of catastrophic thinking (p = 0.02). Conclusion: The effects of the COVID-19 pandemic on patients with chronic pain were not apparent in the short-term.

The ultrasound-guided nerve blocks of abdominal wall contributed to anesthetic management of cholecystectomy in a patient with Becker muscular dystrophy without using muscle relaxants

Abstract Becker muscular dystrophy (BMD) is a progressive neuromuscular disorder caused by mutations in the dystrophin gene. The sensitivity to non-depolarizing muscle relaxant in a patient with muscle dystrophy is reportedly higher than that in normal individuals, and the duration of the effect is known to be prolonged. In this report, we present the case of a 58-year-old man with BMD who underwent laparoscopic cholecystectomy for symptomatic cholelithiasis under total intravenous anesthesia without the use of muscle-relaxant drugs and supplemented with regional anesthesia. Anesthesia was induced and maintained with propofol, remifentanil, and fentanyl; ultrasound-guided bilateral rectus sheath block (RSB) and right-sided subcostal transversus abdominis plane block (TAP) were performed. The procedure required conversion to open surgery because of hard conglutination; intraoperative and postoperative periods were uneventful. Adequate analgesia was maintained after extubation because of the effect of RSB and TAP

Transforaminal epidural blood patch for intractable spontaneous cerebrospinal fluid leak: a case report

Abstract Background Epidural blood patch (EBP) is a recognized treatment for spontaneous cerebrospinal fluid leak (SCFL) and is typically administered by the interlaminar approach. Here, we report a case of a patient in whom SCFL failed to resolve after three applications of interlaminar EBPs before finally being successfully treated with transforaminal EBP. Case presentation We report a case of a 41-year-old female with a definitive diagnosis of SCFL according to computed tomography (CT) myelography. A fluoroscopy-guided interlaminar EBP was applied three times without resolution of her orthostatic headache. A second myelography was therefore performed demonstrating a leak point on the ventral side of the dura mater. To close the ruptured ventral dura mater, it was necessary to fill the ventral epidural space with blood. Therefore, transforaminal EBP was performed. On spinal CT performed immediately after treatment, the ventral epidural space was observed to be filled with injected blood. Her headache improved the following day, and her symptoms completely subsided after 5\ua0days. Conclusion Transforaminal epidural blood patch is appropriate for patients with intractable cerebrospinal fluid leak. Patients with cerebrospinal fluid leakage due to rupture of the ventral side of the dura mater may be particularly good candidates for this procedure

National trends in the outcomes of subarachnoid haemorrhage and the prognostic influence of stroke centre capability in Japan: retrospective cohort study

Objectives To examine the national, 6-year trends in in-hospital clinical outcomes of patients with subarachnoid haemorrhage (SAH) who underwent clipping or coiling and the prognostic influence of temporal trends in the Comprehensive Stroke Center (CSC) capabilities on patient outcomes in Japan.Design Retrospective study.Setting Six hundred and thirty-one primary care institutions in Japan.Participants Forty-five thousand and eleven patients with SAH who were urgently hospitalised, identified using the J-ASPECT Diagnosis Procedure Combination database.Primary and secondary outcome measures Annual number of patients with SAH who remained untreated, or who received clipping or coiling, in-hospital mortality and poor functional outcomes (modified Rankin Scale: 3–6) at discharge. Each CSC was assessed using a validated scoring system (CSC score: 1–25 points).Results In the overall cohort, in-hospital mortality decreased (year for trend, OR (95% CI): 0.97 (0.96 to 0.99)), while the proportion of poor functional outcomes remained unchanged (1.00 (0.98 to 1.02)). The proportion of patients who underwent clipping gradually decreased from 46.6% to 38.5%, while that of those who received coiling and those left untreated gradually increased from 16.9% to 22.6% and 35.4% to 38%, respectively. In-hospital mortality of coiled (0.94 (0.89 to 0.98)) and untreated (0.93 (0.90 to 0.96)) patients decreased, whereas that of clipped patients remained stable. CSC score improvement was associated with increased use of coiling (per 1-point increase, 1.14 (1.08 to 1.20)) but not with short-term patient outcomes regardless of treatment modality.Conclusions The 6-year trends indicated lower in-hospital mortality for patients with SAH (attributable to better outcomes), increased use of coiling and multidisciplinary care for untreated patients. Further increasing CSC capabilities may improve overall outcomes, mainly by increasing the use of coiling. Additional studies are necessary to determine the effect of confounders such as aneurysm complexity on outcomes of clipped patients in the modern endovascular era
