This report concerns an unusual case of acute postoperative pulmonary edema without any apparent causes in a 45-year-old man. The patient was subjected to the removal of a previously placed device on the left tibia, and the excision of a benign mass on the right forearm. Unexpected acute bilateral pulmonary edema occurred immediately after the completion of the procedures. The etiologies were reviewed in relation to the patient's condition and clinical manifestations. Fluid overloading was excluded as a cause in view of the patient's perioperative state and postoperative chest X-ray results. We could not find any symptoms of upper airway obstruction during emergence from general anesthesia. We had doubts about tourniquet or fentanyl-induced pulmonary edema, but these factors were not sufficient to bring about pulmonary edema in this case. To our knowledge, the cause of acute pulmonary edema in this case is indeterminate.

Acute pulmonary edema was induced by intravenous injection of epinephrine, intravenous infusion of dextran and intratracheal instillation of acid solution index was determined from pressure volume curves in excised lungs. Surface activity was also investigated with measurements of maximum and minimum surface tension and stability index on saline extracts of same lungs. The results were as follows. 1. The expansion index of excised lung in which pulmonary edema was induced by intravenous injection of epinephrine, intravenous infusion of dextran and intratracheal instillation of acid solution was ignificantly decreased as compared with the normal control of $0.86{\pm}0.017$ to $0.74{\pm}0.03$, $0.71{\pm}0.081$and $0.76{\pm}0.02$, respectively. 2. The deflation curves of excised lungs in which pulmonary edema was induced were significantly decreased as compared with the normal controls. 3. The minimum surface tension of excised lung in which pulmonary edema was induced was significantly increased in each groups and stability index was significantly decreased as compared with the normal controls 0.78 to $0.35{\pm}0.039$, $0.29{\pm}0.02 $ and $0.31{\pm}0.083$, respectively. 4. The decrease of pulmonary surface activity in acute pulmonary edema was in proportion to the degree of pulmonary edema regardless of their etiology.

This study reports the efficacy of the vasodilator sodium nitroprusside (SNP), for treatment of acute cardiogenic pulmonary edema in dogs. For this study, the patients were divided into the SNP only treatment group, the SNP, furosemide and dobutamine treatment group, and non-SNP treatment group. Seven dogs, 6 dogs and 2 dogs were favorable responders in SNP only group, group with SNP, furosemide and dobutamine and non-SNP treatment group, each. The results of this study suggest that SNP can be an effective alternative therapy for dogs with acute cardiogenic pulmonary edema.

A 6 month-old castrated male Yorkshire terrier (weighing 1.0 kg) was presented with acute respiratory distress. Diagnostic imaging studies found post-obstructive pulmonary edema sequel to upper airway obstruction by a rubber plug lodged at thoracic esophagus. The rubber plug was removed endoscopically. After removal of this rubber plug with conventional therapy for pulmonary edema, the clinical condition of dog was stabilized. To the best knowledge of authors, this is the first case report describing postobstructive pulmonary edema in a dog in Korea.

Nasotracheal intubation is performed routinely in maxillofacial surgery to optimize visualization of the surgical field. The CaldwellLuc operation is an approach to the maxillary sinus through the labiogingival sulcus and canine fossa. The operation is used to treat chronic maxillary sinusitis, and involves curettage of the mucosa of the maxillary sinus and the creation of an inferior meatal antrostomy. After the operation, a nasal Foley catheter is inserted into the inferior nasal meatus for the discharge of blood and tissue fluid. Then, the nostril is packed with vaseline gauze. Before the patients awaken, they experience impaired switching from nasal to oral breathing. Pulmonary edema can result from excessive negative intrathoracic pressure caused by acute airway obstruction in patients breathing spontaneously. During anesthesia and sedation, airway obstruction can occur at the levels of the pharynx and larynx. Even in patients who are awake, alteration in the ability to change the breathing route from nasal to oral may affect breathing in the presence of an airway obstruction, causing this catastrophic event. We experienced a case in which acute pulmonary edema resulted from acute airway obstruction triggered by the patient's inability to switch the breathing route from nasal to oral during emergence from anesthesia.

Certain oriental medication have been shown to be effective in decreasing pulmonary vascular resistance and increasing cardiac output in primary pulmonary artery pressure secondary to pulmonary edema. So oleic acid was administered in 14 dogs in order to induce acute lung injury. And we studied the hemodynamics and blood gas changes of Pyengpaetang(50mg, 100mg) with continuous postive pressure was ventilation in pulmonary edema. The pulmonary edema group, arterial oxygenation was improved after 5 and $10cmH_2O$ PEEP(positive end expiratory pressure), but cardiovascular system was depressed. Blood pressure and cardiac output were decreased, and CVP, MP AP, PCWP were increased. In Pyengpaetang(50mg) group, mean aortic pressure was decreased and PCWP(pulmonary capillary wedge pressure) was decreased remarkably, while there was a significant increase in cardiac output. And there was improvement in $PaO_2$ and $PaCO_2$ without hemodynamic changes after applying 5cm $H_2O$ PEEP, but arterial blood gases$(PaO_2,\;PaCO_2)$ were improved, while cardiovascular effects were depressed after cm $H_2O$ PEEP. In Pyengpaetang(100mg) treated group, there was no significant hemodynamic change. But mean pulmonary arterial pressure was significantly increased, and cardiac output was decreased significantly after applying the more degree of PEEP. And blood gases were not changed significantly after applying the more degree of PEEP. The above results suggest that the effects of Pyengpaetang(50mg) group is superior to those of Pyengpaetang(100mg) group on the effects of hemodynamics and gas exchanges in acute lung injury in dogs. So we can conclude that lower degree PEEP 5cm $H_2O$ is more beneficial in Pyengpaetang(50mg) treated group.

연구배경 : 급성 폐손상은 원인에 상관없이 병태생리학적으로 폐동맥압의 증가와 폐부종을 특징으로 하는데 산소기를 포함한 여러 종류의 염증매개성 물질들이 급성 폐손상의 발병기전에 관여할 것으로 생각되고 있다. 그러나 산소기에 의한 급성 폐손상에서 폐모세혈관압의 변화는 확실하게 알려져 있지 않다. 또한 폐부종의 형성에는 폐포-모세혈관투과성과 함께 폐모세혈관과 폐포사이의 수압차도 중요한 역할을 하는 것으로 알려져 있으나 산소기에 의한 급성 폐손상에서 폐포모세혈관압의 역할에 관해서는 별로 알려져 있지 않은 실정이다. 방법 : Sprague-Dawley 백서를 정상 대조군(n=5), xanthine/xanthine oxidase 처치군(n=7), catalase 전치치군(n=5), papaverine 전처치군(n=7)과 indomethacin 전처치군(n=5)으로 나누어 격리순환폐모델에서 시간경과 따른 폐동맥압, 폐모세혈관압을 측정하고 폐의 무게 변화를 관찰하여 폐부종의 지표로 사용하였다. 폐모세혈관압은 micropuncture에 의한 방법과 일치도가 높은 것으로 알려져 있는 double occlusion법을 이용하였다. 즉, 폐동맥으로의 관류와 좌심방으로부터의 관류를 동시에 2초간 차단하여 폐동맥압과 좌심방압이 비슷한 압력에서 평형상태를 유지할 때의 압력을 폐모세혈관압으로 사용하였다. 결과 : 1) 폐동맥압과 폐모세혈관압은 각각 xanthine/xanthine oxidase 처치군에서 대조군에 비해 유의하게 높았다. 이들은 catalase와 papaverine 전처치로 각각 유의하게 완화되었으나 indomethacin 전처치로는 유의하게 완화되지 않았다. 2) xanthine/xanthine oxidase 처치군에서 관찰된 폐부종은 catalase 천처치와 papaverine 전처치로 유의하게 완화되었으나 indomethacin 전처치로는 완화되지 않았다. 결론 : 격리순환폐모델에서 산소기에 의한 백서의 급성 폐손상시 폐모세혈관압이 증가하고 이는 폐포-모세혈관투과성이 증가된 상태하에서 폐부종을 악화시키며 산소기에 의한 폐모세혈관압의 증가와 폐부종에 cyclooxygenase 대사물은 큰 역할을 하지 않을 것으로 생각된다.
