[Examination of the opportunity costs and turnover situation in patients with deep sternal infections]. / Kostennutzenanalyse der Therapie von Risikopatienten am Beispiel tiefer Sternuminfektionen.

BACKGROUND: Each and every hospital of any kind is forced, due to increased cost pressure, to work as economically and as efficiently as possible. This even applies when the operational orientations of the hospitals institutions are different. In the present article an analysis of the repercussions of the treatment of postoperative complications in terms of entrepreneurial practice is given. Our focus is on the opportunity cost. METHOD: A theoretical calculation of opportunity costs is made based on the example of postoperative infections following cardiac surgery and the resulting treatment. The bases of the examinations are the results collected at the hospital Mediclin Herzentrum Lahr / Baden in 2008. The wound healing disorders were recorded from November 2004 until November 2007 and include 3675 patients who were operated on using a median sternotomy. Out of the 3675 patients 45 (1.2 %) were affected. Various treatment options are at hand. The used therapy algorithm in our practice is dependent on the stage and the development of the infection. RESULTS: If the high trim point, the medial trim point and the low trim point of the mediastinitis patients, as well as the average revenue and the surcharge omission on exceeding the high trim point (these data can be found in the annual accounts) and knowledge of the actual length of stay of the mediastinitis patient are known, the opportunity cost, respectively potential turnover increases, can be calculated. Reducing the medial trim point from 48.43 to, for example, 36.37 days could potentially produce a turnover increase of as much as 10 633.41 €. CONCLUSION: Keeping patient safety in mind, significant turnover increases can be achieved with adequate planning. The considered sales situation, however, can only be achieved under the same terms: these being free operating room and bed capacities, available personnel, equal cost of materials as well as enough patients. The consideration of opportunity costs could be important for entrepreneurs if staff shortage continues and, in economical terms, non-expendable capacities are created.

Successful minimally invasive emergency surgery for descending necrotising mediastinitis.

We present a case of descending necrotising mediastinitis in a healthy young patient, complicated by pneumonia of the right inferior lobe of the lung with parapneumonic effusions. We describe a successful outcome following adequate antibiotics, effective surgical drainage by thoracoscopy and parasternotomy, and hyperbaric oxygen therapy.

Simplified treatment of postoperative mediastinitis.

BACKGROUND: Wound infection after median sternotomy for cardiac or thoracic surgery is a serious complication. A variety of treatment plans have been advocated, and there is lack of agreement regarding the best treatment method. We present our results in patients with mediastinitis who have been treated in a simple, consistent manner. METHODS: We reviewed our experience with 40 consecutive patients with mediastinitis who were treated between January 1995 and May 2003 with a single-stage treatment consisting of sternal and soft tissue debridement and wound closure over mediastinal tubes with continuous irrigation and drainage. Tubes were placed posterior to the sternum in all patients and were irrigated continuously for at least 7 days with antibiotic or antibacterial solution. Systemic antibiotics were selected based on culture and sensitivity data and were administered for 2 to 6 weeks. RESULTS: All patients with mediastinitis treated in this manner survived. Of the 40 patients, 38 achieved complete healing of the wound without further operative intervention or major complication. One patient had recurrent infection and required sternal resection and advancement of muscle flaps. One patient had a residual localized focus of chondritis and underwent limited resection of cartilage. CONCLUSIONS: In this series of patients with postoperative mediastinitis, a simplified approach consisting of wound debridement, reclosure over drains, and anterior mediastinal irrigation has been an effective treatment. The results we have achieved suggest that this technique may be a suitable option for treating this condition.

[A rare case of gaseous gangrenous mediastinitis]. / Rzadki przypadek zgorzeli gazowej sródpiersia.

We report a case of a cervical phlegmone and mediastinitis descending from peridental abscess in 32-year old student. Emergency left thoracotomy was performed after CT evaluation in which multiple fluid levels and gas spaces were found. After 72 hours bacterial strains showed Clostridium perfringens in fluid taken from left pleural cavity and patient was sent to Hiberbaric Center in Gdynia, where he underwent hyperbaric oxygen therapy. After 10 days the patient was brought back in good condition to our Department. After 3 days he died because of sudden massive bleeding caused by necrosis of aorta wall.

[Descending necrotizing mediastinitis: a diagnosis not to miss]. / La cellulite cervico-médiastinale nécrosante: un diagnostic à ne pas méconnaître.

Descending necrotizing mediastinitis is a severe disease which occurs after a mild otorhinolaryngologic or dental infection. The diagnosis must be established rapidly with the help of clinical and computed tomography of the neck and chest data. Treatment is based on antibiotics, surgery and hyperbaric oxygen. The outcome is poor with high mortality. We report a case of septicemia complicating descending necrotizing mediastinitis after dental infection.

Successful treatment of mediastinal gas gangrene due to esophageal perforation.

Esophageal perforation and mediastinal gas gangrene developed in a 55-year-old male after the endoscopic ethanol injection of a Mallory-Weiss ulcer. Initially, extensive gangrene of the esophagus and the mediastinum was treated by esophagectomy; however, an abundance of Clostridium perfringens in the Gram stain verified the presence of gas gangrene. Subsequently, the patient was transferred to a hyperbaric oxygen center, wherein a total of seven hyperbaric treatments were administered. The patient survived, and 4 months later, after having undergone several reoperations because of pleural empyema, mediastinal abscess, splenic rupture, and acalculous cholecystitis, was discharged and is still surviving.

Necrotizing fasciitis and mediastinitis.

Necrotizing fasciitis and mediastinitis are two rare but grave complications of orofacial infections. The clinical presentation, diagnostic modalities, anatomic pathways, microbiologic make-up, surgical management, and the use of adjuvant HBO therapy for both entities have been discussed.

[Necrotizing cervico-mediastinal cellulitis. Apropos of 3 cases]. / Les cellulites cervico-médiastinales nécrosantes. A propos de 3 cas.

OBJECTIVE: To outline the most appropriate treatment of descending necrotizing mediastinitis. MATERIALS AND METHODS: Three adult patients had mediastinitis occurring from a descending odontogenic infection in one case and oropharynx infection in two cases. All patients underwent extensive surgical debridement and a cervicomediastinal drainage through a cervical incision. All patients survived. DISCUSSION: Soft-tissue infections of the neck with mediastinitis demand early diagnosis aided by CT scan in order to decrease their threat to life. Extensive surgical debridement and a cervico mediastinal drainage through a cervical incision is adequate when mediastinitis is limited to the upper mediastinum. Thoracotomy has to be performed when the process spread below the carina. Patients must be treated initially aggressively with the aid of multidisciplinary support team (intensive care physicians, thoracic and head and neck surgeons). Early surgery must treat both neck and mediastin. While usually associated with greater than 40% mortality, all the patients in this series survived.
