We presented the case of cesarean section in a patient with TA. CASE PRESENTATION: A 31-year-old pregnant woman with TA underwent a planned cesarean section at 34 weeks of pregnancy. She had stenosis of the cerebral and coronary arteries and heart failure due to aortic regurgitation. Spinal anesthesia was performed. In addition to standard monitoring, arterial blood pressure in the dorsalis pedis artery and regional cerebral tissue oxygen saturation were monitored. Intraoperative arterial blood pressure was maintained using continuous infusion of noradrenaline with a careful intermittent bolus infusion of phenylephrine. All the procedures were successfully performed without significant complications. CONCLUSIONS: In a pregnant woman with TA, severe stenosis of the cerebral and coronary arteries, and heart failure due to valvular heart disease, careful anesthetic management by selecting catecholamines and assessing the perfusion pressure for critical organs is important..

An English-language version of these guidelines was created based on the contents of the original Japanese-language version. The purpose of this guideline is to assist medical staff in making appropriate decisions to improve the prognosis of patients undergoing treatment for sepsis and septic shock. We aimed to provide high-quality guidelines that are easy to use and understand for specialists, general clinicians, and multidisciplinary medical professionals. J-SSCG 2016 took up new subjects that were not present in SSCG 2016 (e.g., ICU-acquired weakness [ICU-AW], post-intensive care syndrome [PICS], and body temperature management). The J-SSCG 2020 covered a total of 22 areas with four additional new areas (patient- and family-centered care, sepsis treatment system, neuro-intensive treatment, and stress ulcers). A total of 118 important clinical issues (clinical questions, CQs) were extracted regardless of the presence or absence of evidence. These CQs also include those that have been given particular focus within Japan. This is a large-scale guideline covering multiple fields; thus, in addition to the 25 committee members, we had the participation and support of a total of 226 members who are professionals (physicians, nurses, physiotherapists, clinical engineers, and pharmacists) and medical workers with a history of sepsis or critical illness. The GRADE method was adopted for making recommendations, and the modified Delphi method was used to determine recommendations by voting from all committee members.As a result, 79 GRADE-based recommendations, 5 Good Practice Statements (GPS), 18 expert consensuses, 27 answers to background questions (BQs), and summaries of definitions and diagnosis of sepsis were created as responses to 118 CQs. We also incorporated visual information for each CQ according to the time course of treatment, and we will also distribute this as an app. The J-SSCG 2020 is expected to be widely used as a useful bedside guideline in the field of sepsis treatment both in Japan and overseas involving multiple disciplines..

We report two successful cases for which a combination of two existing techniques, modified Robicsek wire fixation and locked titanium plate fixation, was applied to transverse sternal fracture with flail chest. CASE PRESENTATION: One patient experienced a transverse sternal and rib fracture due to a traffic injury. Flail chest due to a highly displaced transverse sternal fracture made withdrawal of the ventilator impossible. Another patient, who developed fulminant myocarditis, experienced a transverse sternal fracture resulting from chest compression during cardiopulmonary resuscitation. Severe paradoxical respiratory movement was a limiting factor for cardiac and respiratory rehabilitation. In both cases, a transverse sternal fracture was difficult to correct non-invasively and indicated surgical repair. The surgical repositioning and fixation greatly contributed to the improvement of the respiratory movement, and the patients were successfully withdrawn ventilator support. CONCLUSION: The combination of modified Robicsek wire fixation and locked titanium plate fixation for a complicated sternal fracture employs the complementary and comparative advantages of each procedure and effective fixation may be achieved..

Ryosuke Nakashima, Masaaki Nishihara, Takeshi Iyonaga, Sho Iwasaka, Yuzo Yamamoto, Yuji Shono, Jun Maki, Kentaro Tokuda, Tomohiko Akahoshi, Taiki Higo, Takanari Kitazono, Hiroyuki Tsutsui, Efficacy of thromboelastography in the management of anticoagulation for veno-venous extracorporeal membrane oxygenation in a coronavirus disease 2019 patient: A case report., Medicine, 10.1097/MD.0000000000026313, Vol.100, No.23, p.e26313, 2021.06, RATIONALE: In coronavirus disease 2019 (COVID-19) patients with acute respiratory distress syndrome refractory to optimal conventional management, we should consider the indication for veno-venous extracorporeal membrane oxygenation (V-V ECMO). Growing evidence indicates that COVID-19 frequently causes coagulopathy, presenting as hypercoagulation and incidental thrombosis. For these reasons, a multifactorial approach with several anticoagulant markers should be considered in the management of anticoagulation using heparin in COVID-19 patients on V-V ECMO. PATIENT CONCERNS: A 48-year-old man was infected with COVID-19 with a worsening condition manifesting as acute respiratory distress syndrome. DIAGNOSES: He was refractory to conventional therapy, thus we decided to introduce V-V ECMO. We used heparin as an anticoagulant therapy for V-V ECMO and adjusted the doses of heparin by careful monitoring of the activated clotting time (ACT) and activated partial thromboplastin time (APTT) to avoid both hemorrhagic and thrombotic complications. We controlled the doses of heparin in the therapeutic ranges of ACT and APTT, but clinical hemorrhaging and profound elevation of coagulant marker became apparent. INTERVENTIONS: Using thromboelastography (TEG; Haemonetics) in addition to ACT and APTT, we were able to clearly detect not only sufficient coagulability of COVID19 on V-V ECMO (citrated rapid thromboelastography-R 0.5 min, angle 75.5°, MA 64.0 mm, citrated functional fibrinogen-MA 20.7 mm) but also an excessive effect of heparin (citrated kaolin -R 42.7 min, citrated kaolin with heparinase 11.7 min). OUTCOMES: Given the TEG findings indicating an excessive heparin effect, the early withdrawal of ECMO was considered. After an evaluation of the patient's respiratory capacity, withdrawal from V-V ECMO was achieved and then anticoagulation was stopped. The hemorrhagic complications and elevated thrombotic marker levels dramatically decreased. LESSONS: TEG monitoring might be a useful option for managing anticoagulation in COVID-19 patients on V-V ECMO frequently showing a hypercoagulative state and requiring massive doses of heparin, to reduce both hemorrhagic and thrombotic complications..

Furthermore, extensive central venous stenosis and/or thrombosis of the superior and inferior vena cava may preclude further catheterization, so uncommon routes must be used, which can be challenging. In such patients, the azygos vein via the intercostal vein is a viable candidate. Thoracotomy-assisted, thoracoscopy-assisted, and cut-down procedures are currently suggested such access. We found that ultrasound-guided percutaneous puncture method was a safe and minimally invasive approach and successfully placed two central venous lines in preparation for small bowel transplantation via two different intercostal veins (ninth and tenth). Although the lung was actually located just below the target veins, an ultrasound provided augmented and clear vision, which contributed to the safe performance of the procedure without the need for invasive surgical intervention, such as thoracotomy, thoracoscopy, or rib resection using the cut-down technique. Furthermore, constant positive-pressure ventilation during vein puncture under general anesthesia also helps avoid venous collapse. Despite carrying a slight risk of light injury to the lung, artery, and nerve along with the vein compared to other procedures, we believe that ultrasound-guided puncture under general anesthesia is feasible as a minimally invasive method..

In light of this situation, the World Health Organization (WHO) declared coronavirus disease 2019 (COVID-19) a pandemic on March 11, 2020. While clinical studies and basic research on a treatment for COVID-19 are ongoing around the world, no treatment has yet been proven to be effective. Several clinical studies have demonstrated the efficacy of chloroquine phosphate and nafamostat mesylate with COVID-19. Here, we report the case of a Japanese patient with COVID-19 with severe respiratory failure who improved following the administration of hydroxychloroquine and continuous hemodiafiltlation with nafamostat mesylate. Hence, hydroxychloroquine with nafamostat mesylate might be a treatment option for severe COVID-19..

Tsukasa Shimauchi, Jun Maki, Jun Yoshino, Naoyuki Fujimura, Sumio Hoka, Effectiveness of arginine vasopressin for the management of refractory hemorrhagic shock in a patient with autonomic dysreflexia caused by spinal cord injury., JA clinical reports, 10.1186/s40981-018-0216-8, Vol.4, No.1, p.79, 2018.11, BACKGROUND: Arginine vasopressin has been used for the management of refractory vasodilatory shock. However, it is still unclear whether arginine vasopressin is useful for hypotension in patients with spinal cord injury. CASE DESCRIPTION: A 78-year-old man with autonomic dysreflexia and paralysis below the level corresponding to Th2 due to spinal cord injury previously underwent cholecystectomy. During the surgery, accidental hemorrhage led him to refractory hemorrhagic shock unresponsive to fluid resuscitation and catecholamine. Lasting hypotension was improved with arginine vasopressin. CONCLUSION: We described a rare case report on the use of arginine vasopressin for management of refractory hemorrhagic shock in a patient with autonomic dysreflexia..

Satomi Mezuki, Yuji Shono, Tomohiko Akahoshi, Kana Hisanaga, Hiroshi Saeki, Yuichiro Nakashima, Kenta Momii, Jun Maki, Kentaro Tokuda, Yoshihiko Maehara, Esophageal perforation due to blunt chest trauma: Difficult diagnosis because of coexisting severe disturbance of consciousness., The American journal of emergency medicine, 10.1016/j.ajem.2017.08.043, Vol.35, No.11, p.1790.e3-1790.e5, 2017.11, Esophageal perforation due to blunt trauma is a rare clinical condition, and the diagnosis is often difficult because patients have few specific symptoms. Delayed diagnosis may result in a fatal clinical course due to mediastinitis and subsequent sepsis. In this article, we describe a 26-year-old man with esophageal perforation due to blunt chest trauma resulting from a motor vehicle accident. Because a severe disturbance of consciousness masked the patient's trauma-induced thoracic symptoms, we required 11h to diagnose the esophageal perforation. Therefore, the patient developed septic shock due to mediastinitis. However, his subsequent clinical course was good because of prompt combined therapy involving surgical repair and medical treatment after the diagnosis..

Takeshi Oda, Hiroshi Yasunaga, Jun Maki, Tsukasa Shimauchi, Yoshifumi Makimoto, Takehito Kawakami, Mau Amako, Takahiro Shojima, Koji Akasu, Akinori Iwasaki, Effectiveness of near-infrared spectroscopy during surgical repair of tracheo-innominate artery fistula., Journal of artificial organs : the official journal of the Japanese Society for Artificial Organs, 10.1007/s10047-011-0565-9, Vol.14, No.3, pp.245-8, 2011.09, Monitoring regional cerebral oxygen saturation (rSO(2)) by use of near-infrared spectroscopy (NIRS) is a useful method for detecting cerebral ischemia. Tracheo-innominate artery fistula is a rare but life-threatening complication of tracheostomy. The surgical procedures for management of tracheo-innominate artery fistula include direct or patch closure of the fistula, ligation or division of the innominate artery, and anatomical or extra-anatomical reconstruction of the flow of the innominate artery. Division of the innominate artery is the best method to prevent postoperative recurrence of bleeding and infection. However, cutting off the innominate artery flow may cause brain ischemia. We present the case of a patient with tracheo-innominate artery fistula successfully treated by dividing the innominate artery while the rSO(2) was monitored. In this case report, we have shown that NIRS is a useful method for deciding the surgical maneuver for tracheo-innominate artery fistula..
