Antibiotic therapy of postoperative bronchopneumonia in patients after lung resections - single-site experience.

INTRODUCTION: Infectious complications after lung surgery are the most important factor that affects mortality and morbidity, prolongs hospital stays and increases financial costs. According to various sources, 30-day mortality after lung resections reaches 123%. Infectious complications account for 2075% of overall mortality. The infections most often present as postoperative pneumonia (POP), and their treatment is based on empirical and targeted antibiotic therapy. Any time lag in initiating effective antibiotic therapy significantly increases morbidity and mortality. Postoperative pneumonia is defined according to current guidelines of the American Thoracic Society of 2016 as nosocomial or ventilator pneumonia in patients after surgery. METHODS: Evaluation of risk factors, infectious agents, morbidity and mortality in patients after lung resections at a single site in the period from 1 January 2018 to 31 December 2019. RESULTS: Of our group of 190 patients, 21 (11.1%) patients had POP which was severe in 6 (33% with POP) patients, and 11 patients with POP required artificial oxygenation for saturation below 92%. Two patients with POP had to be intubated for respiratory failure, and 3 patients required noradrenaline circulatory support. One patient with severe POP died of multiorgan failure after developing refractory sepsis. CONCLUSION: Early identification of lung infection and early initiation of POP therapy are critical points for reducing morbidity and mortality after lung resections. Advanced antibiotic regimens for POP stratify the risk of mortality and infection with multidrug-resistant bacterial strains. However, the regimes require modification according to the epidemiological situation at the site with individualization of the specific procedure. Other research tasks include identification of valid markers of the initial stages of infection, and targeting of antibiotic therapy according to risk stratification and the relationship with physiological flora.

Fistuloclysis as a method of nutritional management in a patient with high output enteroatmospheric fistula - a case report.

Enteric fistula is a pathological communication between the small intestine and surrounding tissue. In case of communication with body surface it is called an enterocutaneous or enteroatmospheric fistula. There are many causes of enterocutaneous/enteroatmospheric fistula occurrence. A common result is malnutrition and organ dysfunction which leads to increased morbidity and mortality of the patients. Adequate nutritional support is a very important element in the management of patients with enterocutaneous/enteroatmospheric fistulas. One of the options of nutritional support is fistuloclysis which means administration of enteral nutrition formula to the distal fistula. We present the case of 76-year-old patient with a high-localized and high output enteroatmospheric fistula in whom we were able to reach adequate nutritional status using fistuloclysis, followed by closure of the fistula.

[Chest wall haemorrhage as a complication of anticoagulation treatment - a case study]. / Krvácení do hrudní steny jako komplikace antikoagulacní lécby - kazuistika.

Low-molecular-weight heparins (LMWH) are a class of medication used as an anticoagulant. They belong amongst the so called direct anticoagulants. The effect on the coagulation cascade is mediated through the inactivation of anti-factor Xa. They are used in prophylaxis of thrombosis because of their lack of fibrinolytic effect. If the dosage is adequate, the effect on the bleeding time is minimal and thus monitoring is not necessary unlike in case of direct anticoagulants. Nevertheless, the monitoring is advisable in patients with renal insufficiency in whom the renal elimination of LMWH and their metabolites is reduced, hence they can cumulate in the organism and increase the risk of various bleeding complications. We present a case study of an 83-year-old patient with a massive subcutaneous haematoma caused by the cumulation of LMWH and with the subsequent huge defect of the chest wall treated with negative wound pressure therapy (Vacuum Assisted Closure - V.A.C.).

[The importance of early surgical intervention in the treatment of necrotizing vasculitis]. / Význam vcasné chirurgické intervence v terapii nekrotizující vaskulitidy.

Vasculitides are an etiologically heterogeneous group of vascular affections leading to vascular wall damage followed by ischaemia of the tissues supplied by the affected vessels. Damage to the vessels of lower extremities is frequent; in serious cases a complete destruction of soft tissue as well as skeletal lesions may occur. This then results in a situation which, without a well-timed surgical intervention, often requires an amputation of the limb. We are presenting a case of a 61-year-old female patient with a large plantar defect of the right foot and gangrene of three toes of the same limb which developed as a result of necrotizing vasculitis.
