  • A clinical evaluation was performed with a population of 49 patients of chest trauma, who were diagnosed to undergo ventilator therapy, and had gone through ventilator therapy at the Department of Thoracic and Cardiovascular Surgery, Kyungpook University Hospital. One of most common causes of chest trauma was vehicle accidents [77.5%] with the prevalent age group being their forties. The common findings were multiple rib fractures [89.8%], hemopneumothrax [81.6%], lung contusion [61.2%] and flail chest [44.9%]. Their common combined injuries were the orthopedics and neurosugical injuries [86.7%]. Complications caused by chest trauma were pneumonia, respiratory failure, atelectasis, barotrauma and empyema. Pulmonary infections were commonly associated with mechanical ventilation in the long term group and were best prevented by using bronchial hygiene therapy.The mortality rate was 5.8% of the total patients and that was 38.8% of the patients, who needed ventilator therapy. The causes of death were pneumonia, respiratory failure, acute renal failure and hypovolemic shock. Mechanical ventilation has an important place in the treatment of patients with severe chest trauma.

  • PURPOSE: To prevent secondary complications from decreased pulmonary functions and promote neurological recovery, identification of respiratory capacity change patterns depending on different postures of stroke patients and investigation of their properties are needed for active rehabilitation. Therefore, this study was conducted to investigate the changes in vital capacity in response to different positions and to implement the results as clinical data. METHODS: A respiratory function test was administered to 52 patients with stroke in the sitting, supine, paretic side lying, and non-paretic side lying positions. Pulmonary function indexes used for comparison were forced vital capacity (FVC), forced expiratory volume at 1 second (FEV1), forced expiratory flow 25-75% (FEF 25-75%), and maximum voluntary ventilation (MVV). One-way repeated ANOVA was used for analysis, and post hoc analysis was conducted using least significant difference (LSD). RESULTS: All pulmonary function indexes were measured in the order of sitting, paretic side lying, supine, and non-paretic side lying positions. Excluding the FEF25-75% and MVV of the supine compared with the paretic side lying position, all other pulmonary function indexes differed significantly (p<.05). CONCLUSION: There are differences in pulmonary function indexes depending on different postures of stroke patients, and the study showed that the non-paretic side lying position yielded the greatest effect on lung ventilation mechanisms. Based on these results, appropriate postures need to be considered during physical therapy interventions for stroke patients.

  • Objective: To investigate the effects of stellate ganglion block (SGB) on the peri-operative vasomotor cytokine content and intrapulmonary shunt in patients with esophagus cancer who underwent thoracotomy. Materials and Methods: Forty patients undergoing elective resection of esophageal cancer patients who had I~II American Society of Anesthesiologist (ASA) were randomly divided into total intravenous anesthesia group (group N, n=20) and total intravenous anesthesia combined with SGB group (group S, n=20, 0.12 mL/kg 1% lidocaine was used for SGB 10 min before induction). Heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), mean pulmonary arterial pressure (MPAP) and continuous cardiac output (CCO) were continuously monitored. The blood from internal jugular vein was drawn respectively before induction ($T_0$), and 30 min ($T_1$), 60 min ($T_2$) and 120 min ($T_3$) after one-lung ventilation (OLV), and 30 min (T4) after two-lung ventilation. The contents of plasma endothelin (ET), nitric oxide (NO) and calcitonin gene-related peptide (CGRP) were detected with enzyme linked immunosorbent assay (ELISA). Meanwhile, arterial and mixed venous blood samples were collected for determination of blood gas and calculation of intrapulmonary shunt fraction (Qs/Qt). Results: During OLV, ET contents were increased significantly in two groups (P<0.05), and no significant difference was presented (P>0.05). NO content in group S was obviously higher than in group N at T3 (P<0.05), whereas CGRP content in group N was markedly lower than in group S at each time point (P<0.05). Qs/Qt was significantly increased in both groups after OLV, but there was no statistical significant regarding the Qs/Qt at each time point between two groups. Conclusions: Total intravenous anesthesia combined with SGB is conducive to regulation of perioperative vasomotor cytokines in thoracotomy, and has little effect on intrapulmonary shunt at the time of OLV.

  • In this paper, I present the technique of subxiphoid single-port video-assisted thoracic surgery (VATS) thymectomy for thoracic surgeons to perform this procedure safely. This procedure is indicated for all anterior mediastinal masses and may be extended to lung cancer. The patient is placed in the lithotomy position, and the operator should be on the midline. Below the xiphoid process, a skin incision is made 4-5 cm horizontally at a single thumb's width down. Under two-lung ventilation, CO2 is insufflated, maintaining 10 mm Hg. The fat tissue and thymic tissue are all resected from the sternum and pericardium between both phrenic nerves using an articulated grasper and an energy device. After retrieval of the mass with a wrap bag, a Jackson-Pratt drain is inserted instead of a chest tube. One of the advantages of this procedure is less postoperative pain than intercostal VATS. The subxiphoid approach can be used for bilateral pneumothorax, bilateral pulmonary metastasectomy, and simple lobectomy for both upper lobes and the right middle lobe.

  • Purpose: Prolonged ventilation leads to a higher incidence of ventilator-associated pneumonia (VAP), resulting in weaning failure and increased medical costs. The aim of this study was to analyze clinical results and prognostic factors of VAP in patients with blunt chest trauma. Methods: From 2007 to 2011, one hundred patients undergoing mechanical ventilation for more than 48 hours were divided into two groups: a VAP-negative group, (32 patients, mean age; 53 years, M:F=25:7) and a VAP- positive group, (68 patients, mean age; 60 years, M:F=56:12). VAP was diagnosed using clinical symptoms, radiologic findings and microorganisms. The injury severity score (ISS), shock, combined injuries, computerized tomographic pulmonary findings, transfusion, chronic obstructive lung disease (COPD), ventilation time, stay in intensive care unit (ICU) and hospital stays, complications such as sepsis or disseminated intravascular coagulation (DIC) and microorganisms were analyzed. Chi square, t-test, Mann-Whitney U test and logistic regression analysies were used with SPSS 18 software. Results: Age, sex, ISS, shock and combined injuries showed no differences between the VAP - negative group and - positive group (p>0.05), but ventilation time, ICU and hospital stays, blood transfusion and complications such as sepsis or DIC showed significant differencies (p<0.05). Four patients(13%) showed no clinical symptoms eventhough blood cultures were positive. Regardless of VAP, mortality-related factors were shock (p=0.036), transfusion (p=0.042), COPD (p=0.029), mechanical ventilation time (p=0.011), ICU stay (p=0.032), and sepsis (p=0.000). Microorgnisms were MRSA(43%), pseudomonas(24%), acinetobacter(16%), streptococcus(9%), klebsiela(4%), staphillococus aureus(4%). However there was no difference in mortality between the two groups. Conclusion: VAP itself was not related with mortality. Consideration of mortality-related factors for VAP and its aggressive treatment play important roles in improving patient outcomes.

  • Objectives : Among the various types of minimally invasive spine surgeries, thoracoscopic surgery is becoming more widely accepted and increasingly utilized. This report delineates our clinical experience using thoracoscopy to resect herniated thoracic discs in 16 patients who suffered from myelopathy or intolerable radiculopathy. Patients and Methods : Between Mar. 1997 and Sep. 1999, 16 consecutive patients underwent thoracoscopic discectomy for treatment of herniated thoracic discs. There were 12 men and 4 women(mean age 43.5 years ; range 18-61 years). Eleven patients presented with myelopathic signs and symptoms from spinal cord compression and 5 patients had incapacitating thoracic radicular pain without myelopathy. The surgical level was varied between T3 and T12. The pathology of specimen were 11 hard discs and 5 soft discs herniations. Thoracoscopic techniques were performed with long narrow spine instruments and high speed drill through 3 or 4 ports under one lung ventilated general anesthesia. During the operation three patients were converted to open thoracotomy due to intolerable one lung ventilation, excessive bleeding and inadequate operation field. The mean operation time was 264min.(range : 100-420min.), and postoperative mean admission period was 11 days. Results : Clinical and neurological outcomes were good in all patients(mean follow-up period 20 months). Among the eleven myelopathic patients, 8 improved neurologically, and 3 stabilized. Among the five radiculopathic patients, 4 recovered completely and no patient had worsened. Postoperative complications were pleural effusion in one case, intercostal neuralgia in one, delayed hemopneumothorax in one, prolonged air leakage in one and pneumonia in one case. Conclusions : Thoracoscopic discectomy needs a steep learning curve to be familiar to anatomical space and handling of endoscopic instruments. However, it is technically feasible and can be effectively performed with acceptable results.

  • Backgrounds: Endotoxin, which found in the outer membrane of the gram-negative bacteria cell wall, makes up almost all of the lipopolysaccharide(LPS). When people are exposed to endotoxin,it can result in diverse health effects such as an airway irritation and inflammation, fever, malaise, bronchitis, allergic asthma, toxic pneumonitis, hypersensitivity lung disease. Cases among the elderly, children or pregnant can occur more frequently than a healthy adult if they are repeatedly exposed to the existing endotoxin. Therefore, we investigated and assessed the environmental characteristics associated with the airborne endotoxin concentration level in six hospital lobbies. Method: Endotoxin from indoor air in six hospital lobbies was measured by an area sampling method and analyzed according to American Society for Testing and Materials International(ASTM international) E2144-01. Total suspended particulate(TSP), carbon dioxide($CO_2$), temperature and humidity were also measured by using direct reading measurements or airborne sampling equipment at the same time. Environmental characteristics were appropriately divided into two or three groups for a statistics analysis. One-way analysis variable(one-way ANOVA) was used to examine a difference of the endotoxin concentration, depending on the environmental characteristics. In addition, only variables with p-value(p<0.25) were eventually designed to the best model by using multiple regression analysis. Results: The correlation analysis result indicated that TSP(p=0.003) and $CO_2$(p<0.0001) levels were significantly associated with endotoxin concentration levels. In contrast, temperature(p<0.068) and humidity(p<0.365) were not associated with endotoxin concentration. Levels of endotoxin concentration were statistically different among the environmental characteristics of Service time(p=0.01), Establishment of hospital(p<0.001), Scale of hospital(p=0.01), Day average people using hospital(p=0.03), Cleaning time of lobby(p=0.05), Season(p<0.001), and Cleaning of ventilation system(p<0.001) according to ANOVA. Finally, the best model(Adjusted R-square=72%) that we designed through a multiple regression test included environmental characteristics related to Service time, Area of lobby, Season, Cleaning of ventilation system, and Temperature. Conclusions: According to this study, our result showed a normal level of endotoxin concentration in the hospital lobbies and found environmental management methods to reduce the level of endotoxin concentration to a minimum. Consequently, this study recognized to be requirement for the management of ventilation systems and an indoor temperature in order to reduce the level of endotoxin concentration in the hospital lobbies.

  • Massive hemoptysis is a life-threatening condition and sometimes leads to death due to airway obstruction rather than exsanguinations. In a critical hemoptysis, endotracheal intubation may be necessary to maintain adequate gas exchange and protect the unaffected side of the lung. Bronchial blockers (BBs), commonly used technique for one-lung ventilation in thoracic or cardiac surgeries, are valuable devices for protecting the airway in massive endobronchial bleeding. We report three cases intubated with BBs, Univent$^{(R)}$, in massive hemoptysis. We suggest that BBs are one of the indispensable equipments for respiratory specialized wards and intensive care units.
