北極海マカロフ海盆での冬季水増加に伴う栄養塩躍層の浅化

北極海における近年の急激な海氷減少は北極海の気候や生態系にさまざまな変化を引き起こしてきた。例えば、カナダ海盆では海氷融解に伴う淡水化や酸性化、海洋循環の強化、栄養塩躍層の深化とそれに伴う生物生産の低下、巨大渦の出現とその影響による植物プランクトン量の増加などが観測されるようになってきた。これらの現象はいずれもアラスカ側北極海で観測されたものである。しかし、シベリア側北極海はデータが少なく、どのような変化が起きているのかはほとんど分かっていない。本研究ではロシアEEZ海域のデータを含む複数船舶のデータを活用し、シベリア側北極海での海氷減少に伴う水塊構造の変化と低次生態系への影響について議論する。要旨 ; 2013年度日本海洋学会春季大会（2013年3月21日～3月25日, 東京海洋大学）http://www.godac.jamstec.go.jp/darwin/cruise/mirai/mr04-05/ehttp://www.godac.jamstec.go.jp/darwin/cruise/mirai/mr08-04/

Esophageal submucosal hematoma developed after endovascular surgery for unruptured cerebral aneurysm under general anesthesia: a case report

Abstract Background Esophageal submucosal hematoma is a rare complication after endovascular surgery. We report a case of an esophageal submucosal hematoma which may have been caused by rigorous cough during extubation. Case presentation A 75-year-old woman underwent endovascular treatment for unruptured cerebral aneurysm under general anesthesia. The patient received aspirin and clopidogrel before surgery and heparin during surgery. Activated clotting time was 316 s at the end of surgery. Protamine was not administered and continuous infusion of argatroban was started after surgery. She had a rigorous cough during removal of the tracheal tube and reported retrosternal discomfort postoperatively. She developed hemorrhagic shock after massive hematemesis. A diagnosis of esophageal submucosal hematoma was made by endoscopic examination and computed tomography. Hemostasis was achieved by compression with a Sengstaken-Blakemore tube and endoscopic cauterization. Blood pressure was recovered by blood transfusion. Endoscopic examination performed 7 days after surgery showed that esophageal submucosal hematoma had almost disappeared and slough had adhered to the mucosal laceration. The patient showed good recovery and was discharged 21 days after surgery. Conclusions Careful extubation and postoperative observation are required in patients receiving antiplatelet and anticoagulant therapy
