RESUMEN
A study was carried out to assess treatment success and the overall costs of patients with ventilator-associated pneumonia (VAP). In a prospective case control study, data were collected from 25 intensive care unit (ICU) beds. A total of 162 ICU patients who required mechanical ventilation were assessed. Of these, 81 patients were diagnosed with VAP and the other 81 were controls (without VAP). Risk of mortality was analyzed and total cost of care was recorded. Age, sex and underlying disease were similar between the groups. The mean length of stay (LOS) in the ICUs in the VAP cases (15.7±9.1 days) exceeded that of the controls (4.9±4.9 days) (p 0.0001), and the additional LOS attributable to VAP was estimated at 10.8 days. In the VAP group, 25 patients had early-onset VAP, and the other 56 patients had late-onset VAP. Mortality rates were higher in VAP patients (32%) than controls (19.7%) p 0.05). Total costs were USD 8602.7±5045.5 in the VAP group and USD 2621.9±2053.3 in controls. The additional cost for VAP was found to be USD 5980 per patient. These data suggest that morbidity, mortality, ICU length of stay and costs increase with VAP. The additional costs for VAP are especially based on the use of novel and expensive antibiotics, other drugs, and medical material.

OBJECTIVE: Various techniques to reduce air space after pulmonary lobectomy especially for lung cancer have been an important concern in thoracic surgical practice. The aim of this study was to assess the effectiveness of Botulinum toxin A (BTX-A) injection into the diaphragm to reduce air space after right lower pulmonary lobectomy in an animal model. METHODS: Twelve male New Zealand rabbits were randomly allocated into two groups. All animals underwent right lower lobectomy. Then, normal saline of 0,1 ml and 10 units of 0,1 ml Botulinum toxin type A were injected into the muscular part of the right hemidiaphragm in control (n = 6) and BTX-A groups (n = 6) respectively. Residual air space and diaphragmatic elevation were evaluated with chest X-ray pre- and postoperatively. Diaphragmatic elevation was measured as a distance in millimetre from the line connecting the 10th ribs to the midpoint of the right hemidiaphragm. RESULTS: The mean diaphragmatic elevation in BTX-A and control groups were 7.0 +/- 2.5 and 1.3 +/- 1.2 millimetres respectively. Diaphragmatic elevations were significantly higher in BTX-A group (p = 0.0035). CONCLUSION: Intraoperative Botulinum toxin type A injection may reduce postlobectomy spaces effectively via hemidiaphragmatic paralysis in rabbits. Further studies are needed to validate the safe use of Botulinum toxin type A in human beings.
RESUMEN
OBJECTIVE: To determine the incidence, reasons and prognosis about Horner's syndrome in thoracic surgical patients. METHODS: In this prospective clinical study, 933 adult patients were assessed between the years of 1998 and 2002. All patients who underwent chest tube insertion (n: 662 patients) or thoracotomy (n: 342 patients), or who had thoracic trauma (n: 268 patients) were routinely examined to detect of Horner's syndrome. The patients with Horner's syndrome due to the invasion of malignant tumour to sympathetic chain were not included in the study. RESULTS: Horner's syndrome was detected in twelve patients from these 933 patients (1.3%). The considered etiologic factors were chest tube pressure in five patients, operative complication in two patients and trauma in five patients. In patients with chest tube pressure were fully recovered from Horner's syndrome but the remaining did not. CONCLUSIONS: Malposition of the chest tube is an important aetiological factor of Horner's syndrome, and it is reversible if the tube position is corrected urgently.
