Abstract PDF

Background
Recently developed taper-shaped cuffs (TG cuffs) of endotracheal tubes (ETTs) are known to have a more potent sealing effect than cylindrical high-volume low-pressure cuffs (HL cuffs) of conventional ETTs. The aim of this study was to compare TG cuffs with HL cuffs of ETTs in a bench-top model with regard to air leakage under various positive end-expiratory pressures (PEEP).
Methods
HL cuffs and TG cuffs made from PVC were included (HL group vs. TG group). A model trachea with an internal diameter (ID) of 22 mm was attached to a test lung. The test lung was ventilated using an anesthesia respirator with volume controlled mode and PEEPs of 0, 5, 10, or 15 cm H₂O. Using spirometry, percentages of expired to inspired tidal volumes (TVe/i) were calculated as a measure of air leakage.
Results
With regard to PEEPs, the HL group showed significantly higher air leakage compared to the TG group (p < 0.0001), and a higher PEEP resulted in greater air leakage (p < 0.0001). Air leakage with higher PEEP was greater in the HL group than in the TG group at ID 7.0 mm and 7.5 mm (p = 0.0467, p = 0.0045)
Conclusions
This study shows the superior sealing ability of the TG cuff during ventilation at various PEEPs.

Abstract PDF

Background
Endotracheal suctioning is associated with complications that include bleeding, infection, hypoxemia, cardiovascular instability, and tracheal mucosal injury. Recently, a closed-suction catheter with a pressure valve (Acetrachcare, AceMedical Co., Republic of Korea) was developed. We hypothesized that this new catheter might reduce tracheal mucosal injury compared to a conventional closed-suction catheter (Trachcare, Kimberly-balla RD, USA).
Methods
This prospective, randomized study enrolled medical and surgical patients who required mechanical ventilation for more than 48 hours. Patients were randomized into two groups: one group was suctioned with the conventional closed-suction catheter (CCC) and the other group was suctioned with the closed-suction catheter with pressure valve (CCPV). Bronchoscopy was performed 48 hours later, and the severity of tracheal mucosal injury was graded on a 5-point scale, as follows: 0 = normal; 1 = erythema or edema; 2 = erosion; 3 = hemorrhage; and 4 = ulceration or necrosis.
Results
A total of 76 patients (37 with CCPV and 39 with CCC) were included. There were no significant differences between the groups regarding demographic characteristics, changes in hemodynamic parameters during suction, incidence of pneumonia, length of intensive care unit (ICU) stay, or ICU mortality. On bronchoscopic evaluation, the use of the CCPV led to a significant decrease in tracheal mucosal injury (median tracheal mucosal injury grade 1 [IQR 0-1] vs. 2 [IQR 1-3], p = 0.001).
Conclusions
We conclude that the novel closed-suction catheter with pressure valve may reduce tracheal mucosal injury compared to conventional catheters.

Abstract PDF: Background
Pneumothorax (PTX) can occur as a complication of positive pressure ventilation in mechanically ventilated patients.
Methods
We retrospectively reviewed the clinical characteristics of patients who developed PTX during mechanical ventilation (MV) in the intensive care unit (ICU).
Results
Of the 326 patients admitted (208 men and 118 women; mean age, 65.3 ± 8.74 years), 15 (4.7%) developed PTX, which was MV-associated in 11 (3.3%) cases (6 men and 5 women; mean age, 68.3 ± 9.12 years) and procedure-associated in 4. Among the patients with MV-associated PTX, the underlying lung diseases were acute respiratory distress syndrome in 7 patients, interstitial lung disease in 2 patients, and chronic obstructive pulmonary disease in 2 patients. PTX diagnosis was achieved by chest radiography alone in 9 patients and chest computed tomography alone in 2 patients. Nine patients were using assist-control mode MV with the mean applied positive end-expiratory pressure, 9 ± 4.6 cmH₂O and the mean tidal volume, 361 ± 63.7 ml at the diagnosis of PTX. Two patients died as a result of MV-associated PTX and their systolic pressure was below 80 mmHg and heart rates were less than 80/min. Ten patients were treated by chest tube insertion, and 1 patient was treated by percutaneous pigtail catheter insertion.
Conclusions
PTX can develop in patients undergoing MV, and may cause death. Early recognition and treatment are necessary to prevent hemodynamic compromise in patients who develop PTX.

Abstract PDF: Tachycardia-induced cardiomyopathy is caused by persistent tarchyarrhythmias and is characterized by ventricular systolic dysfunction and congestive heart failure. Tachycardia-induced cardiomyopathy is usually reversible via treatment. The cornerstone in the management of disease in these patients is to achieve a normal heart rate. We report a torsades de pointes during treatment of tachycardia-induced cardiomyopathy. Intravenous magnesium sulfate and potassium were administrated, but torsades de pointes was repeated. After overdrive right ventricular pacing, torsades de pointes was terminated. Careful monitoring of the QT interval and serum electrolyte and drug levels in such patients is warranted during treatment of tachycardia-induced cardiomyopathy.

Abstract PDF: Kawasaki disease (KD) is an acute, systemic vasculitis of childhood. The early mortality of KD results from coronary complications, mainly aneurysmal thrombosis with myocardial infarction, and the subacute phase of KD has the highest risk of mortality. Although there have been reports of ischemic heart disease as late cardiologic sequelae of KD in young adults, acute myocardial infarction caused by coronary complications in the subacute phase of KD is rare. We experienced one pediatric patient who developed coronary artery aneurysm and acute myocardiac infarction (AMI) during the subacute phase of incomplete and intravenous immunoglobulin (IVIG)-nonresponsive KD. The patient was given a good prognosis due to close monitoring and early recognition of AMI. Physicians should carefully monitor KD patients who do not respond to initial IVIG therapy and who show progressive coronary artery dilatation. If such a patient complaints of chest pain and the ECG shows hyperacute T waves, the physician should suspect development of AMI.

Abstract PDF: This report describes a case of systemic thromboembolism caused by left ventricular (LV) thrombosis that developed after placement of an implantable cardioverter-defibrillator (ICD). A 27-year-old male patient was diagnosed with idiopathic dilated cardiomyopathy and ventricular tachycardia, and underwent ICD implantation for the primary prevention of sudden cardiac death. Two weeks after ICD implantation, the patient experienced renal infarction. Transthoracic echocardiography revealed a mobile thrombus at the LV apex, and automated function imaging demonstrated deteriorated LV function after ICD implantation. The RV was not placed by ICD and the mechanical force which was occurred by ICD that led to induced dyssynchronous motion of the LV apex may have resulted in a systemic thromboembolism.

Abstract PDF: A 25-year-old man developed tracheal stenosis due to prolonged intubation for five days. Immediately after bougienage, his left lung was not possible to ventilate and emergency tracheostomy was performed to produce ample space for airflow. Fiberoptic bronchoscopy showed that his left main bronchus was totally obstructed by sputum at the entrance of the superior and inferior lobar bronchi. Inadequate airway clearance increases the risk of infection and airway obstruction. We suggest chest physiotherapy be applied to all patients in the intensive care unit (ICU), especially patients with tracheal stenosis, due to its positive impact on pulmonary functional ability and ICU stay.

Abstract PDF

Foreign body aspiration into the tracheobronchial tree can cause serious problems. Tooth aspiration can occur during emergency endotracheal intubation. However, removal of a tooth from the airway is difficult because of the round shape and smooth surface of the tooth. Here, I report extraction of a tooth from the airway by flexible bronchoscopy using fishnet basket in intensive care patients. The procedure was performed in six patients. All patients were critically ill with an artificial airway (n = 4; endotracheal tube, n = 2; tracheostomy tube). The tooth location was right bronchial tree in three patients and left bronchial tree in three patients. Tooth extraction failed in two patients because the teeth were impacted in the distal bronchus during bronchoscopy. There was no complication such as life threatening arrhythmia or hypoxemia during the procedure. Using flexible bronchoscopy with a fishnet basket, we were able to extract aspirated teeth from patients with an artificial airway.

Abstract PDF

Hemolytic uremic syndrome (HUS) is defined by the triad of mechanical intravascular hemolytic anemia with schistocytosis, thrombocytopenia and acute renal failure. Pulmonary involvement in HUS is known to be rare. We present the case of a 25-year-old male with diffuse alveolar hemorrhage and myocarditis followed by atypical hemolytic uremic syndrome. In this case, successful treatments included steroid pulse therapy for the fatal alveolar hemorrhage and plasma exchange for the hemolytic uremic syndrome.

Abstract PDF

Extracorporeal membrane oxygenation (ECMO) is a means for supporting adequate gas exchange in patients with severe respiratory failure and is the only therapeutic option for ventilation-refractory patients awaiting lung transplantation. Moreover, defining the patients likely to benefit from ECMO as a bridge to transplantation has recently become a point of interest. Here, we report a case of prolonged ECMO support to a patient awaiting lung transplantation. A 66-year-old woman was diagnosed with acute interstitial pneumonia and was placed on veno-venous (VV) ECMO due to unsatisfactory gas exchange despite maximal ventilator care. She underwent bilateral lung transplantation after 99 days of ECMO and was successfully weaned from it on the 107th ECMO day. This is the longest period of ECMO support to be reported among elderly patients.

Abstract PDF: Myocardial dysfunction can occur during severe sepsis and may accelerate in the condition of chronic decompensated heart failure. A 26-year-old female in remission from non-Hodgkin’s lymphoma presented with shock due to chronic heart failure combined with pneumonia. The patient was initially stabilized using a peripheral extracorporeal membrane oxygenator (ECMO) with antibiotics therapy, followed by left ventricular venting due to pulmonary edema that was complicated by left ventricular distension. Here, we report the successful application of ECMO to a patient with pneumonia underlying doxorubicin-induced cardiomyopathy. Although septic conditions remained unclear indication of ECMO, it might be considered a valuable therapeutic option in patients with chronic heart failure.
