Alternate suction reduces prolonged air leak after pulmonary lobectomy: a randomized comparison versus water seal.

BACKGROUND: The objective of the present study was to compare in a prospective randomized fashion two different management schemes for chest tubes after lobectomy: water seal versus alternate suction (suction overnight and water seal during the day). METHODS: Ninety-four patients with air leak on the morning of the first postoperative day were randomly assigned to two groups: group 1 (water seal alone), 47 patients; or group 2 (alternate suction), 47 patients. The groups were then compared in terms of preoperative, operative, and postoperative variables. RESULTS: Alternate suction patients showed a reduced incidence of air leak longer than 4 days (p = 0.04) and longer than 7 days (p = 0.02), a shorter duration of chest tubes in place (p = 0.002), and a shorter postoperative hospital stay (p = 0.004). CONCLUSIONS: Alternate suction was superior to water seal alone in reducing the incidence of prolonged air leak and postoperative hospital stay after lobectomy. As suction was applied only overnight, this modality has the same advantage of water seal in terms of early mobilization of patients.

Functional improvement after volume reduction: sternotomy versus videoendoscopic approach.

BACKGROUND: Volume reduction has been proved to increase ventilatory mechanics in diffuse, nonbullous lung emphysema. However, the best approach is still controversial. METHODS: We retrospectively compared the perioperative data of and functional results in 15 patients having sternotomy (group I) with those of 15 patients having a videoendoscopic approach (group II). RESULTS: The 30-day mortality was 2 patients in group I and 1 patient in group II. Mean duration of chest tube drainage was 8.7 +/- 1.8 days and 8.0 +/- 1.9 days and mean hospital stay, 12.3 +/- 1.9 and 12.5 +/- 2.1 days in groups I and II, respectively. Work of breathing decreased from 1.89 +/- 0.33 J/L and 1.76 +/- 0.22 J/L preoperatively to 0.75 +/- 0.06 J/L and 0.8 +/- 0.06 J/L (p < 0.01 and p < 0.05, respectively) after 3 months; and intrinsic positive end-expiratory pressure decreased from 7.15 +/- 1.31 cm H2O and 6.24 +/- 1.33 cm H2O to preoperatively 0.79 +/- 0.46 cm H2O and 1.13 +/- 0.44 cm H2O (p < 0.005 and p < 0.01, respectively) after 3 months in groups I and II, respectively. Forced expiratory volume in 1 second increased from preoperative values of 21.6% +/- 2.9% and 25.3% +/- 2.4% of predicted to 34.5% +/- 5.0% and 40.9% +/- 7.5% of predicted after 3 months (p < 0.05 in both groups) in groups I and II, respectively. CONCLUSIONS: Both surgical approaches resulted in similar substantial improvement in lung function and physical fitness. The incidence of air leakage, the duration of chest tube drainage, and the hospital stay were the same for both procedures.

Spontaneous hemothorax in a hemodialysis patient.

An 8-year-old girl who had undergone chronic hemodialysis for 1 year presented with respiratory distress 24 h after a hemodialysis session. She had a massive pleural effusion of the left chest that was shown to be hemothorax by thoracentesis. After chest tube insertion, drainage was maintained for 2 days. Pleural effusion recurred after withdrawal of the chest tube. The antecubital arteriovenous fistula on the left arm was found to have an excessive flow with a thrill which was felt all over her left shoulder and left hemithorax. The pleural effusion resolved spontaneously a week after ligation of the fistula. Excessive flow in the arteriovenous fistula was thought to be the cause of the hemothorax and should be included in the differential diagnosis of hemothorax in hemodialysis patients.

Tissue plasminogen activator combined with human recombinant deoxyribonuclease is effective therapy for empyema in a rabbit model.

OBJECTIVES: There have been no controlled studies to test the efficacy of tissue plasminogen activator (tPA) or recombinant human deoxyribonuclease (rhDNase) in the treatment of empyema. In vitro studies show that streptokinase without rhDNase does not liquefy empyemic material from rabbits. However, the combination of streptokinase and streptodornase and rhDNase have been shown to liquefy pus in vitro. The aim of this study was to determine if tPA or rhDNase, or a combination of the two, is more effective than saline solution in the treatment of empyema in rabbits. MATERIALS AND METHODS: Empyema was induced in rabbits using 10(9) Pasteurella multicoda organisms in infusion agar injected via a surgically placed chest tube. Once empyema was verified, a blinded investigator administered one of four treatments via the chest tube: 3 mL of saline solution; 4 mg of alteplase (recombinant tPA); 1 mg of rhDNase; or 4 mg of alteplase and 1 mg of rhDNase. The rabbits received a treatment every 12 h following the initial for a total of six treatments. The animals were killed at day 10, and the degree of empyema and pleural peel was scored macroscopically on a scale of 0 to 4. RESULTS: The combination group had a significantly lower mean empyema score (1.83 +/- 0.75) than did the saline solution group (3.86 +/- 0.38, p = 0.001), rhDNase group (3.17 +/- 0.75, p = 0.012), and alteplase group (3.71 +/- 0.49, p = 0.02) [+/- SD]. The total volume of pleural fluid was markedly higher in the alteplase and rhDNase combination group (142 +/- 79.1 mL) or the alteplase group (231 +/- 78.0 mL) compared to either the rhDNase group (0.8 +/- 1.6 mL) or the saline solution group (5.8 +/- 14.0 mL). CONCLUSION: The combination of alteplase and rhDNase is more effective in the treatment of rabbit empyema than either agent alone. The intrapleural injection of alteplase alone or in combination with rhDNase leads to the production of large amounts of pleural fluid.

CT-guided catheter drainage of loculated thoracic air collections in mechanically ventilated patients with acute respiratory distress syndrome.

OBJECTIVE: We report our experience with CT-guided percutaneous catheter drainage of loculated thoracic air collections in mechanically ventilated patients with acute lung injury or acute respiratory distress syndrome. MATERIALS AND METHODS: Nine critically ill patients had 17 air collections (13 pneumothoraces, three pneumatoceles, one tension pneumomediastinum) that either developed despite the presence of standard surgical chest tubes or were in loculated sites that were difficult to access. All nine patients were ventilated mechanically for a clinical diagnosis of acute respiratory distress syndrome. Catheter size ranged from 7- to 28-French. Response was measured by imaging follow-up, ventilatory parameters, and clinical outcome. RESULTS: On follow-up imaging studies, all 17 air collections were shown to have been evacuated successfully. Catheters remained in place for a mean of 11 days (range, 4-28 days). No major complications occurred. Sixteen air collections were treated successfully with CT-guided catheter placement alone; the remaining air collection, a pneumothorax, was treated with subsequent placement of a chest tube by the surgeon at the patient's bedside. No surgery was undertaken for the air collections. Improvement in gas exchange was documented by increase in the hypoxemia ratio (arterial oxygen pressure divided by the inspired fraction of oxygen) in seven of 12 drainages; the other drainages were accompanied either by no improvement or by deterioration. Eight (89%) of the nine patients eventually were extubated and discharged from the hospital. The ninth patient died. CONCLUSION: CT-guided percutaneous catheter drainage provided effective treatment for loculated thoracic air collections and obviated surgical intervention in these critically ill, high-surgical-risk patients.

Plasmatic [corrected] factor XIII reduces severe pleural effusion in children after open-heart surgery.

Chylous effusions frequently occur after cardiac surgery due to severe damage to the lymphatic system, thus indicating that the insertion of a chest tube may be necessary. Factor XIII (FXIII) is discussed as being essential for wound healing. The aim of this retrospective study was to evaluate whether the application of a single dose of FXIII results in a reduced amount of pleural effusion, leading to an earlier release of patients from the hospital. The cases of 40 children with severe chylous effusions after open-heart surgery were examined. Twenty patients received FXIII and were compared to 20 age- and weight-matched patients who did not receive FXIII. Major parameters included the amount of effusion before and 1 and 3 days after the application of FXIII; the duration of chest tubes; the total amount of fluid loss via drainage; and the period of hospitalization. FXIII levels in plasma showed an inverse correlation with fluid loss. After application of a single dose of FXIII, a significant reduction of pleural effusion within the first 24 hours was detected. However, no difference was observed between the two groups when comparing the total amount of pleural effusions within the first 72 hours. Finally, the duration of hospitalization did not differ between the FXIII-treated and the control group. A single application of FXIII rapidly reduces the amount of chylous effusions in the early period after open-heart surgery. This effect is detectable only for 24 hours after the treatment and does not alter the further clinical outcome. Prospective clinical trials are warranted to determine if repeated application or a higher dose of FXIII may improve the clinical outcome of chylous leakages in children after open-heart surgery.

Treatment of complicated parapneumonic pleural effusion with intrapleural streptokinase in children.

OBJECTIVE: To evaluate the role of intrapleural streptokinase in the management of complicated parapneumonic effusions in children. DESIGN: Prospective comparative study. SETTING: Cheng Kung University Hospital, a tertiary medical center in Tainan, Taiwan. PATIENTS AND METHODS: We enrolled as our prospective study group 20 consecutive children with complicated parapneumonic effusions who received intrapleural streptokinase treatment between August 2000 and July 2002. We also retrospectively analyzed a comparison group of 22 consecutive children with complicated parapneumonic effusions who received chest tube drainage without streptokinase treatment from January 1992 to July 2000. We then compared the clinical manifestations and outcome of these two patient groups. The patient population (21 boys and 21 girls) ranged in age from 9 to 130 months (mean age, 41.5 +/- 26.3 months [mean +/- SD]). The characters of pleural effusion showed no difference between the two groups. Nineteen patients had positive findings for Streptococcus pneumoniae, 2 patients had positive findings for Staphylococcus aureus, 2 patients had positive findings for Pseudomonas aeruginosa, and 19 patients had undetermined pathogens. All patients were treated with appropriate antibiotics. RESULTS: More pleural fluid was drained from the streptokinase group than from the comparison group during streptokinase treatment (816 +/- 481 mL vs 279 +/- 238 mL, p < 0.01). The duration of fever after chest tube insertion was also significantly lower in the study group (5.3 +/- 3.1 days vs 7.9 +/- 4.6 days, p < 0.05). Only two patients in the streptokinase group required surgical intervention compared with nine patients in the comparison group (p < 0.05). No major side effects were noticed after streptokinase instillation. CONCLUSION: Intrapleural fibrinolytic treatment with streptokinase is safe and effective, and it can obviate the need for surgery in most cases. The combination treatment should be attempted early on, when complicated parapneumonic effusion is first diagnosed.

Posttraumatic empyema. Risk factor analysis.

BACKGROUND: Empyema remains a distressing complication after thoracic injury. OBJECTIVE: To identify high-risk factors associated with the development of empyema. DESIGN: Retrospective cohort review. SETTING: University hospital, level I trauma center. PATIENTS: Trauma patients who required tube thoracostomy (TT) between January 1, 1991, and November 31, 1993 (n = 584). METHODS: Data (demographic characteristics, injuries, chest x-ray film reports, and setting of TT) were assessed using a stepwise logistic regression analysis to identify risk factors associated with the development of post-traumatic empyema. RESULTS: Empyema that required decortication developed in 25 patients (4%). Factors predictive of development of empyema were retained hemothorax (odds ratio, 12.5; 95% confidence interval, 0.96-163), pulmonary contusion (odds ratio, 6.3; 95% confidence interval, 1.53-25.8), and multiple chest tube placement (odds ratio, 2.5; 95% confidence interval, 1.91-3.28); factors not predictive of empyema were severity of injury, mechanism of injury, setting in which TT was performed, number of days chest tubes were in place, and antibiotic drugs at the time of TT. CONCLUSIONS: The extent of pulmonary injury (pulmonary contusion) is an important predictor of empyema development. Previously implicated factors such as setting in which a TT was performed and mechanism of injury did not correlate with the development of posttraumatic empyema. Based on the results of our study, we recommend early drainage of the pleural space with video-assisted thoracoscopic techniques in patients at risk of empyema, which may spare them the morbidity of a thoracotomy.

Talcage by medical thoracoscopy for primary spontaneous pneumothorax is more cost-effective than drainage: a randomised study.

Simple thoracoscopic talcage (TT) is a safe and effective treatment of primary spontaneous pneumothorax (PSP). However, its efficacy has not previously been estimated in comparison with standard conservative therapy (pleural drainage (PD)). In this prospective randomised comparison of two well-established procedures of treating PSP requiring at least a chest tube, cost-effectiveness, safety and pain control was evaluated in 108 patients with PSP (61 TT and 47 PD). Patients in both groups had comparable clinical characteristics. Drainage and hospitalisation duration were similar in TT and PD patients. There were no complications in either group. The immediate success rate was different: after prolonged drainage (>7 days), 10 out of 47 PD patients, but only 1 out of 61 TT patients required a TT as a second procedure. Total costs of hospitalisation including any treatment procedure were not significantly different between TT and PD patients. Pain, measured daily by visual analogue scales, was statistically higher during the first 3 days in TT patients but not in those patients receiving opiates. One month after leaving hospital, there was no significant difference in residual pain or full working ability: 20 out of 58 (34%) versus 10 out of 47 (21%) and 36 out of 61 (59%) versus 26 out of 39 (67%) in TT versus PD groups, respectively. After 5 yrs of follow-up, there had been only three out of 59 (5%) recurrences of pneumothorax after TT, but 16 out of 47 (34%) after conservative treatment by PD. Cost calculation favoured TT pleurodesis especially with regard to recurrences. In conclusion, thoracoscopic talc pleurodesis under local anaesthesia is superior to conservative treatment by chest tube drainage in cases of primary spontaneous pneumothorax that fail simple aspiration, provided there is efficient control of pain by opioids.

Computed tomography in children with esophageal and airway trauma.

Computed tomography (CT) was used in five children, four with esophageal and one with airway trauma. The examination contributed valuable information that aided in planning and evaluating therapy: (1) it assessed mediastinal and pleural cavity involvement prior to surgery or drainage; (2) it evaluated the efficacy of drainage; (3) it gave excellent information about the position of chest tubes; and (4) it demonstrated unsuspected pneumothoraces, pleural effusion, pulmonary infiltrates, and lung perforation by a chest tube. In the postoperative assessment of laryngotracheal fracture, neck radiographs were useless since the airways were obliterated by hematomas and edema. In this situation, CT showed the position and state of the laryngeal cartilages. However, CT findings were not pathognomonic for esophageal tears or airway fractures. The primary diagnosis was still made by conventional radiography. Esophageal tears were accurately demonstrated by gastrografin swallow and the tracheolaryngeal fracture was diagnosed by a lateral neck radiograph--the state of the child permitting no lengthy workup. CT and conventional radiography with contrast studies play a complementary role in esophageal and airway trauma in children.

Histopathologic diagnosis made in lung tissue resected from patients with severe emphysema undergoing lung volume reduction surgery.

STUDY OBJECTIVES: This study reports histopathologic findings in a group of emphysema patients who underwent thoracoscopic lung volume reduction surgery (75) or sternotomy (five) with the purpose to induce functional improvement and relief of dyspnea. Immediate outcome and complications were correlated to histologic patterns. DESIGN: Histopathologic material obtained in lung volume reduction surgery in 80 consecutive patients was analyzed. Thirty patients who had other histopathologic diagnoses in addition to emphysema were grouped and compared with 50 patients found to have emphysema exclusively. Postoperative outcome and preoperative lung function variables were compared. MEASUREMENTS AND RESULTS: All patients had severe obstructive lung disease and significant air trapping preoperatively documented by pulmonary function testing. All had severe exertional dyspnea. All had chest radiographs, CT, and nuclear medicine lung scans consistent only with emphysema. All portions of resected lung tissue were weighed, lung volume was estimated, and routine histopathologic studies were made. Thirty patients (37.5%) had unsuspected findings such as interstitial fibrosis, noncaseating granulomatosis, chronic inflammation, and unsuspected neoplasia (three carcinomas, one carcinoid). Retrospective review of imaging studies in these patients failed to show infiltrative processes. The average lung weight resected in this group was significantly heavier (65+/-18 g) compared with the other group (56+/-13 g), although both had the same estimated lung volume. Average number of days requiring chest tubes and length of hospitalization was also significantly higher (12.8+/-19 vs 6.4+/-5 days with chest tubes and 17.4+/-22 vs 8.5+/-6 days of hospitalization, respectively). None of the preoperative pulmonary function tests variables were different between the two groups. Serious postoperative complications were more frequent in these patients compared with those who showed only emphysema. CONCLUSIONS: A significant portion of patients diagnosed as having severe emphysema will have other unsuspected histologic findings. When subjected to lung volume reduction surgery, this subgroup will have more serious complications and longer periods of air leaks, requiring longer hospitalization time. Retrospective review of imaging studies and preoperative pulmonary function tests used to select patients for lung volume reduction failed to identify this subgroup.

Ultra-low dose aprotinin effects on reducing the need for blood transfusion in cardiac surgery.

OBJECTIVE: To assess the effects of ultra-low dose one million kallikrein inhibitor units (KIU) of aprotinin on bleeding and the need for transfusion after cardiac surgery. METHODS: We carried out this randomized clinical trial on 162 cardiac surgery patients in Shahid Madani Hospital, Tabriz, Iran from April 2004 to December 2005. The patients were randomly divided into 2 groups of 81 individuals. In the aprotinin group, 0.5 million KIU infused before and 0.5 million KIU during cardiopulmonary bypass. In the placebo group, 100 ml normal saline was infused as above. The need to use fresh frozen plasma (FFP), packed red blood cells (PRBCs) transfusion during, after operation, the rate of chest tubes drainage at 6, 12 and 24 hours after surgery were measured in 2 groups. RESULTS: Chest tubes drainage at 6 hours after surgery was 190 +/- 24 ml in the aprotinin group and 266 +/- 33 ml in the placebo group (p=0.066). The amount of bleeding at 12 and 24 hours was significantly different between 2 groups (p=0.048, p=0.009). The frequency of blood products transfusion in the aprotinin group was 68% and in the placebo group was 75% (p=0.02). The number of PRBCs and FFP units transfused were significantly lower in the aprotinin group (p=0.000, p=0.005). Total amount of blood and products transfusion in the aprotinin group was 2.56 +/- 0.27 units and in placebo group it was 4.37 +/- 0.27 units (p=0.0001). CONCLUSION: Results indicate that the use of one million KIU of aprotinin in cardiac surgery is effective in reducing postoperative bleeding and transfusion requirements.

Chemical pleurodesis with doxycycline 1 g.

We evaluated the utility of a single 1-g dose of doxycycline in the treatment of malignant and nonmalignant pleural effusions and refractory pneumothoraces in 27 consecutive patients requiring pleurodesis. After the evacuation of all retained air or fluid, and premedication with intravenous narcotic analgesics and intrapleural lidocaine 200 mg, the patients received doxycycline 1 g in 50 ml normal saline instilled through the chest tube. This was followed by instillation of 100-200 ml of air to facilitate dispersion. The chest tube was removed when the drainage was less than 150 ml/day. Twenty-three of 27 patients were evaluated at 30 days. Six (67%) of the nine patients with pneumothoraces achieved a response, and both patients with nonmalignant pleural effusions had a complete response. Of the 12 patients with malignant pleural effusion, 8 (67%) achieved a complete response, 2 had a partial response, and 2 had no response. Twenty-two (81%) of 27 patients experienced adverse effects with pleurodesis, with pain (81%) and fever (11%) being the most prevalent. In this limited number of patients, doxycycline 1 g appeared to be safe and effective for the treatment of pleural effusions and pneumothoraces. The 1-g dose must be compared with the standard 500-mg dose and with other established agents.

Role of the trauma-room chest x-ray film in assessing the patient with severe blunt traumatic injury.

OBJECTIVES: To examine the accuracy of standard trauma-room chest x-ray films in assessing blunt abdominal trauma and to determine the significance of missed injuries under these circumstances. DESIGN: A retrospective review. SETTING: A regional trauma unit in a tertiary-care institution. PATIENTS: Multiply injured trauma patients admitted between January 1988 and December 1990 who died within 24 hours of injury and in whom an autopsy was done. INTERVENTION: Standard radiography of the chest. MAIN OUTCOME MEASURES: Chest injuries diagnosed and recorded by the trauma room team from standard anteroposterior x-ray films compared with the findings at autopsy and with review of the films by a staff radiologist initially having no knowledge of the injuries and later, if injuries remained undetected, having knowledge of the autopsy findings. RESULTS: Thirty-seven patients met the study criteria, and their cases were reviewed. In 11 cases, significant injuries were noted at autopsy and not by the trauma-room team, and in 7 cases these injuries were also missed by the reviewing radiologist. Injuries missed by the team were: multiple rib fractures (11 cases), sternal fractures (3 cases), diaphragmatic tear (2 cases) and intimal aortic tear (1 case). In five cases, chest tubes were not inserted despite the presence (undiagnosed) of multiple rib fractures and need for intubation and positive-pressure ventilation. CONCLUSIONS: Significant blunt abdominal trauma, potentially requiring operative management or chest-tube insertion, may be missed on the initial anteroposterior chest x-ray film. Caution must therefore be exercised in interpreting these films in the trauma resuscitation room.

MAST augmentation of external cardiac compression: role of changing intrapleural pressure.

Ventricular fibrillation was induced in nine dogs weighing 18 to 22 kg. CPR was performed with a mechanical chest compressor. Mean carotid flow during CPR was 7.9 +/- 1.5 ml/min. After MAST inflation to 100 mm Hg, the flow increased to 15.7 +/- 3.7 ml/min. Intrathoracic aortic systolic pressure was also significantly increased from 65 +/- 7 to 73 +/- 8 mm Hg. When the thorax was vented with chest tubes bilaterally, no change in carotid flow or arterial pressure was noted on closing or opening the chest tubes. One liver laceration and two gallbladder contusions were noted at autopsy. MAST inflation apparently augments carotid flow an systolic pressure. Variations in intrapleural pressure do not seem to have a significant influence on CPR.

Complications of intermittent prone positioning in pediatric patients receiving extracorporeal membrane oxygenation for respiratory failure.

STUDY OBJECTIVE: To describe the safety and risks of placing pediatric patients in the prone position during extracorporeal membrane oxygenation (ECMO) for the treatment of respiratory failure. DESIGN: Single-center retrospective cohort study. SETTING: Tertiary pediatric ICUs. PATIENTS: All patients admitted to the pediatric ICU who required ECMO for respiratory failure from 1995 to 2000. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: Medical records for 93 patients representing 95 ECMO runs for treatment of respiratory failure were reviewed. Of these, 63 patients (66%) received intermittent prone positioning. Demographic data and clinical information were recorded. The median age was 12 months, and the median weight was 9.8 kg. There were 962 position changes. Complications surveyed for included bleeding from appliance insertion sites, appliance dislodgment, unplanned extubation, cutaneous pressure ulceration, corneal abrasion, and extreme hemodynamic instability. These complications were noted as to whether they were present prior to the initiation of prone positioning or whether they developed after prone positioning began. Twenty-four percent of patients had bleeding from cannulation sites prior to prone positioning, and 18% of patients had bleeding begin after prone positioning was initiated. Two patients had chest tubes dislodge after prone positioning began, but neither patient had bleeding occur or required reinsertion of the chest tube. There were no unplanned extubations, appliance displacements, development of cutaneous pressure ulcerations, or corneal abrasions associated with prone-positioning maneuvers. No patient had ECMO support removed secondary to the surveyed complications. Eighty-two percent of children who received prone positioning during ECMO for treatment of respiratory failure survived to hospital discharge. CONCLUSION: We found that prone positioning may be used in pediatric ECMO patients without increasing the risk of complications. A multi-institutional, prospective, randomized, controlled study would better evaluate the efficacy of this practice and whether it is associated with a shorter length of ECMO or shorter post-ECMO ventilation and outcome.

Percutaneous catheter drainage of pleural effusion and empyema.

Fluoroscopy-guided percutaneous catheter drainage (PCD) was used in 38 patients to diagnose and/or treat pleural effusions (21), hemothorax (one), symptomatic malignant effusions (four), and empyemas (12). Fluoroscopic guidance combined with the use of a small needle, J-tip guide wire, and pigtail catheter made it possible to safely drain both free and loculated fluid collections, including areas with difficult access. In 11 of the 12 patients with empyema, the pus (or purulent fluid) was successfully drained using PCD. Two or more catheters were used in all but one patient. In four of the empyemas, PCD was used successfully after incomplete or unsuccessful chest tube drainage. In five, PCD was used as the sole means of drainage. In three patients, chest-tube drainage was used to drain residual (one) or recurrent (two) empyemas after PCD. The safety and relative ease of PCD makes it an attractive alternative method for closed drainage of pleural fluid collections.
