If the hemorrhage from postextraction wound is unusually aggressive, and then dehydration and airway problem are occurred, the socket must be packed with gelatine sponge(gelfoam) that was moistened with thrombin and wound closure & pressure dressing are applied. The thrombin clots fibrinogen to produce rapid hemostasis. Gelatine sponges moistened with thrombin provide effective coagulation of hemorrhage from small veins and capillaries. But, in dental alveoli, gelatine sponges may absorb oral microorganisms and cause alveolar osteitis (infection). This is a case report of bleeding and infection control by the circumferential suture and iodoform gauze drainage on infected active bleeding extraction socket under sedation and local anesthesia in a 71-years-old male patient with anticoagulation drug.

2 178 대한치과마취과학회지 : 제 11 권제 2 호 2011 자극이과도해오심과구토의가능성이높아지는등심각한응급상황에직면할수있다 (Conley, 1979; Laskin, 1985; Falace, 1995). 또한계속되는출혈로인한순환혈류량의감소는완서관류조직 ( 내장, 근육, 피부 ) 의혈액이급서관류조직 ( 심장, 폐, 뇌, 신장 ) 으로이동되는혈역학의변화로심신의약화가초래되며, 과도한출혈은저혈량성쇼크의발생으로생명의위협을가져올수있다 ( 김진복등, 1987). 따라서구강내과다출혈을신속정확하게지혈시키고후처치를제대로시행함은환자의전신건강관리에매우중요하며, 이런점에서치과임상에서발치를시행할때는사전에환자의병력과신체검진을철저히시행해서발치후출혈의원인들에대한파악을하고그에따른적절한관리를신속정확히시행함이매우중요하다. 발치후초기단계에서과도한출혈의주요원인들에는 (1) 창상감염, 괴혈병, 화학물질에의한혈관벽취약 (2) 유전, 아스피린같은약물, 자가면역질환에의한혈소판기능장애, (3) 방사선, 백혈병같은혈소판감소성자반증, (4) 혈우병, 크리스마스질환같은선천성응고장애, (5) 간장질환, 비타민결핍, 쿠마린, 헤파린, 아스피린, 플라빅스 (plavix) 같은항응고약제등에의한후천성응고장애들이있다 (Patton & Ship, 1994; Rodgers, 1999; Little et al, 2002). 만약발치창출혈이매우과도해서전신탈수와기도문제가위협된다면발치창상은통상적으로봉합술을시행하거나트롬빈 (thrombin) 을적신젤라틴스폰지 (gelfoam) 등으로채워서창상봉합과압박지혈을시도하게된다. 트롬빈은신속한지혈을형성하려고피브리노겐을직접응고시킨다. 그러나발치된치조와내부에서젤폼은구강내미생물을흡수해서발치와골염 ( 감염 ) 을야기해창상치유를지연시키는동통과 2차적출혈을더야기할수도있어사용에신중을기해야하며, 2차적후출혈발생시대책도마련되어있어야한다 (Kruger, 1984; Bonoliel et al, 1986; Falace, 1995). 이런면들을종합적으로고려할때치과임상에서는충치나치주염증이과도한경우에발치의적응증이될정도의치성감염치아들도가능한한발치보다는약물요법, 근관치료, 절개배농술같은출혈이적은술식을구사해서치성감염을감소시키고, Fig. 1. Initial panoramic view. 관련의학과의협진과임상병리검사 ( 흔히 CBC, P.T., P.T.T. 등 ) 를통해발치후출혈문제를확인한후에발치를시행하게된다 (Kelly, 1990; Steinberg & Moores, 1995; Sonis et al, 1995). 이원칙에따라서본과에서는고혈압, 협심증, 뇌졸중, 위장관질환등으로항응고제를투여하던환자에서, 관련의학과 ( 심장내과등 ) 의협진으로국소마취하에충치와치주염이과도한상악대구치에서 1차근관치료를계획했다. 그러나근관치료도중치아가발치되면서과도한출혈이계속되어, 응급으로습윤거즈압박지혈하에진정요법과에피네프린함유국소마취보강후에, 발치창상테두리봉합과요오드포름거즈배농술및수액약물 ( 항생제등 ) 요법으로, 창상출혈과감염을힘들게조절한증례를체험해이를보고한다. 증례보고 70세남환이상악좌측제2대구치 ( 치식 : #27) 의심한충치와치주염으로과도한동요도를가진잔존치근의통증해소를위해발치를해달라고본과에내원했다. 구강검사와방사선사진검사결과과도한치성감염상태여서발치의적응증은되었으나 (Fig. 1), 전신병력상다발성내과질환으로발치시출혈위험이크고 2차적감염에따른창상치유도불량할것같아, 관련의학과자문을구한후에발치보다는 1차치근관신경치료 ( 치관제거, 발수및치근관개방통한배농술등 ) 가적절하다고판단되었다. 왜냐하면이환자는약 20년간고혈압관리를받았고, 약 3년전부터협심증과심근경색증, 약 2년전교통사고로지주막하출혈이있어뇌수술을받았으며,

6 182 대한치과마취과학회지 : 제 11 권제 2 호 2011 즉출혈되는발치창주위의염증조직 (granulation tissue) 들을제거해창상내부를확인하고발치창테두리봉합술을시행한다음에발치창내부의비어있는공간 ( 사강 : dead space 역할 ) 에는압박지혈에도움을얻고새로형성되는혈종 (hematoma) 과장액종 (seroma) 의배액로 (drainage route) 로도도움을얻기위해요오드포름거즈 (iodoform gauze: 상품명 Nugauze) 를채워넣는유출재방법을적용한다음습윤압박거즈를다물고있게함 (biting) 으로써확실한지혈을이루게했다. 하지만발치창상치유기전상창상감염에관련된요소들이 Table 4처럼많이있고 (Topazian & Goldburg, 1981), 기존의혈액응고기전에장애가상당했기에통상적으로이용되는국소지혈제 (gelfoam, Surgicel, Fibrin sealant 등 ) 사용은오히려발치창상내부감염만조장할뿐응급지혈에는도움이되지않기에사용치않았다. 또한보트로파제등전신적지혈약제들은약물부작용으로혈전형성의우려가있어 ( 최현림등, 2003) 심장질환이있는환자에서는사용상큰주의가요망되기에, 본환자의경우는사용치않았다. 결론적으로저자등은본증례의치험을통해치과임상에서 Plavix같은항응고제를투여하는환자의진행성치성감염조절에있어서는가능한한출혈이거의없는치근관신경치료가우선적으로고려되어야하지만, 부득이발치가시행되는경우에는관련의학과협진하에진정요법과국소마취로발치창상부테두리봉합술과유출재 (iodoform gauze) 삽입으로압박지혈과감염조절을달성함이바람직하리라사료된다. 참고문헌 김진복, 김춘규, 이용각, 장선택 : 최신외과학, 제 1 판. 서울, 일조각. 1987, pp 민병일 : 악안면성형외과학. 서울, 군자출판사. 1990, pp 최현림, 김수영, 김철환, 신호철, 이혜리, 조경환등 : 가정의학, 임상편. 서울, 계축문화사. 2003, pp Bonoliel R, Leviner E, Katz J: Dental treatment for the patient on anticoagulant therapy.
