Results of femoral vein catheterization were compared with those of subclavian and antecubital vein catheterization in 2,345 combat casualties during treatment of hypovolemic shock. Femoral vein catheterization was successful in 95.5 per cent of cases. Accidental arterial puncture occurred in 6.3 per cent, hematomas in 1.3 per cent, and infection in 1.4 per cent. Subclavian vein catheterization was successful in 92.4 per cent. Arterial puncture occurred in 0.4 per cent, hematomas in 0.3 per cent, infection in 1.1 per cent, pneumothorax in 1.4 per cent, and hydrothorax in 0.4 per cent. Antecubital vein catheterization was successful in 77.6 per cent, infection developed in 3.3 per cent, and phlebitis occurred in 5.6 per cent. No clinically detectable phlebitis occurred after either femoral or subclavian vein catheterization. The low morbidity of femoral vein catheterization in this series suggests that this approach be considered when short-term massive intravenous fluid administration is indicated in the treatment of circulatory collapse or cardiac arrest.

The majority of life-threatening injuries secondary to the placement of central venous catheters, such as bleeding and pneumothorax, occur at the time of initial insertion. When a catheter extravasates in the neck, edema of the neck wall or chest is usually seen, and the pump indicates occlusion. We present four cases in which an uneventful, successful placement of four central lines (three superior vena cava, one inferior vena cava) were followed at greater than 48 hours by either hydrothorax or hydroperitoneum, which resulted in either cardiorespiratory collapse or intraabdominal sepsis. In reviewing these cases, all showed both a change in catheter location on a subsequent x-ray and poor or no blood return on aspiration; paradoxically, the infusion pump in each case did not sense a catheter malposition or occlusion. We conclude that, although the success of central line placement may be documented on insertion, a continual reappraisal of both the function and location of the line is necessary.

Large pleural effusions are typically associated with dyspnea and potential respiratory compromise. Experimental evidence suggests that with large effusions, increased intrapleural pressure may be transmitted to the pericardial space, resulting in impaired cardiac filling and reduced stroke volume. We report two cases in which large pleural collections were complicated by hypotension. The effusions were due to an infected right hepatic hydrothorax (Case 1) and a left malignant effusion (Case 2). Echocardiography demonstrated right and left ventricular diastolic collapse, respectively, confirming a diagnosis of cardiac tamponade. Large volume thoracentesis resulted in immediate hemodynamic improvement as demonstrated by a reduction in right ventricular and atrial pressures (Case 1) and echocardiographic resolution of left ventricular diastolic collapse (Case 2). These cases establish that large pleural effusions can cause hemodynamically significant cardiac tamponade. In addition, they illustrate how the demonstration of cardiac compressive physiology can significantly alter the therapeutic approach to large pleural effusions.

We report a case of delayed pneumothorax, central venous catheter migration and iatrogenic hydrothorax in a 22-year-old female. The left subclavian central venous catheter initially transfixed the lung apex; pneumothorax occurred 24 h later following initiation of positive pressure ventilation. Lung collapse as a result of the pneumothorax caused catheter migration and hydrothorax. Catheter removal and chest drainage led to an uneventful recovery.

One hundred and one (6%) of 1,678 patient studied had bilateral reexpansion pulmonary oedema(RPO). On the whole, one thousand, seven hundred and seventy nine (1,779) pleural spaces were studied, fifteen pleural spaces (0.8%), with mean age of 23 +/- 4.5 years had RPO. Among these 15 patients with RPO, the mean period of lung collapse before pneumothorax (PThx) was evacuated was 31.8 +/- 21.8 days and for hydrothorax (HThx) was 31.3 +/- 30.1 days; for 15 patients without RPO (controls), matched for age and sex, the mean period of lung collapse before CTTD was 7.5 +/- 4.1 days and 5.4 +/- 1.3 days respectively for PThx and HThx. The differences in the period of lung collapse among patients with RPO and those without, for each pleural disease was statistically significant (P < 0.03). Volume of pleural fluid drained before RPO was noticed was 2196 +/- 1103 mls, for the 15 matched patients without RPO (controls), it was 1060 +/- 115 mls (p < 0.05). Volume of pleural fluid drained among the patients with SR (Severe response), MR (mild to moderate response) and RD (radiological diagnosis) did not correlate with severity of response. We conclude that prevention of RPO is the desired goal in the management of pleural effusion or Pneumothorax. RPO is commonest among young patients who have had lung collapse for 7 or more days. In these circumstances RPO is prevented, its incidence and severity reduced by methods of gradual evacuation of PThx or pleural fluid drainage.

Although the accumulation of gas is the most common cause of an expanding interpleural space, the presence of other structures or substances (hydrothorax, gastrothorax, hemothorax, urohemothorax, pyothorax, and chylothorax) under pressure may be sufficient to cause hemodynamic and respiratory compromise. We present two pediatric patients that developed hemodynamic and respiratory effects secondary to a chylothorax. The first patient presented in respiratory distress and cardiovascular collapse 4 weeks after a Fontan procedure. Placement of a chest tube resulted in the release of chyle under pressure and prompt resolution of hemodynamic and respiratory symptoms. The second patient was a 2100 g neonate who developed a chylothorax during an episode of sepsis following gastroschisis repair. On two separate occasions, the development of the chylothorax was associated with tachycardia, oliguria, and increased requirements during mechanical ventilation. Chest tube placement resulted in the release of chyle under pressure and resolution of the symptoms. These two cases demonstrate that chylothorax like pneumothorax can have deleterious effects on hemodynamic and respiratory function.

In the neonatal population, pleural effusion and particularly tension pneumothorax can be a deadly situation. Pneumothorax occurs more often in the neonatal period that any other time of life. Tension pneumothorax can result in very high pressures within the pleural space, collapsing the lung on the involved side and resulting in immediate hypoxia, hypercapnia and subsequent circulatory collapse. For these reasons, the ability to recognize, understand and treat these pathologies is essential for neonatal health and a good outcome. Neonates have many factors that can contribute to. these problems. These include respiratory distress syndrome, mechanical ventilation, sepsis, pneumonia, aspiration of meconium, congentital malformation, hydrothorax, congenital or acquired chylothorax. The diagnosis can be made by clinical examination, transillumination (pneumothorax) and chest x-ray. Besides, lung ultrasound constitutes a visual medicine and provides a transparent approach to the acutely ill patient, newborn included, guiding diagnosis, management and care. Newborns with moderate to severe symptoms and those receiving positive pressure ventilation require tube thoracostomy. If a tension pneumothorax is suspected, emergency needle decompression in the second intercostal space in the midclavicular line is required. In this article, we describe the management of tube thoracostomy using trocar tubes or pigtail catheters. Besides, we pay attention to the use of pain control for neonates undergoing painful procedures such as chest tube insertion.

Hydrothorax occurs frequently in patients with endstage liver disease and usually requires drainage of pulmonary effusion during the hepatectomy phase of liver transplant. Reexpansion pulmonary edema is a rare but potentially fatal complication seen after rapid reexpansion of the collapsed lung following thoracentesis of pleural fluid or tube drainage of pneumothorax. This condition, which manifests with various degrees of clinical severity, is rarely reported following liver transplantation. Herein, we present a 62-year-old male patient who developed reexpansion pulmonary edema after drainage of massive pleural effusion, which caused a total collapse in the right hemithorax during liver transplant. Six hours after pleural fluid drainage, the patient developed a nonproductive cough, mild tachypnea, shortness of breath, and low oxygen saturation (88%). His chest radiograph showed diffuse heterogeneous opacities in the right hemithorax. Computed tomography of the thorax revealed consolidations containing air bronchograms and ground glass opacities in the parenchyma of the right lung; these findings did not extend to the periphery and were observed less frequently in the inferoposterior left lung. These symptoms and radiologic findings were diagnosed as reexpansion pulmonary edema. Complete clinical and radiologic improvements were achieved within 72 hours of mechanical ventilatory support.

Meigs syndrome is the triad of ascites, hydrothorax, and benign ovarian tumor (mostly fibroids). It is a diagnosis of exclusion, and the characteristic symptoms disappear after resection of the tumor. Instead, in Pseudo-Meigs syndrome, the triad includes a nonfibroma ovarian tumor. The latter may consist of benign tumors (ie, of fallopian tube or uterus, struma ovarii, and ovarian leiomyomas) but can also comprise ovarian or metastatic gastrointestinal malignancies.The authors describe a case of sudden death in a 43-year-old woman, with no noteworthy reported history of present illness or medical history and in apparently good health before death.The autopsy showed a picture of bilateral hydrothorax with lung collapse, ascites, and a large left-sided ovarian mass, approximately 15 cm in diameter. Histopathological examinations revealed an ovarian epithelial malignancy (cystadenocarcinoma). There was also lung atelectasis with accompanying thrombosis of small and medium blood vessels. The combination of autopsy and histological findings allowed us to establish the diagnosis of Pseudo-Meigs syndrome, undiagnosed antemortem, resulting in death due to pulmonary and thrombotic complications. Our subsequent review of the literature found no case reports of undiagnosed Pseudo-Meigs syndrome presenting as sudden death, highlighting the uniqueness of the case presented herein.

Chest tube is a flexible plastic tube used to discharge secretion in the cavity between the lungs and chest named pleural cavity. Normally, there is a small amount of fluid in the cavity between the lungs and chest; This fluid helps the movement of lungs during breathing without abrasion. Entrance of bit of air, blood or pus because injury in the pleural cavity can prevent the lungs from fully opening. Full or partial collapse of the lungs makes breathing difficult and can lead to respiratory arrest; putting chest tube in the pleural cavity causes the discharge of secretion and helps patients comfort. Chest Electro-Drainage mobile system is designed to drain air, blood, water and pus accumulated in the space between the visceral and parietal pleural cavity. Based on low volume and weight, this system can be used to treat Pneumothorax, Hemothorax and Hydrothorax and so forth, both in the emergency state and treatment centers. Obviously, this system will be an action to reduce deaths especially in the case of Pneumothorax.
