When should a chest radiograph be obtained after chest tube removal in mechanically ventilated patients? A prospective study

BACKGROUND: The purpose of this study was to determine the appropriate time interval between the removal of a chest tube and the chest radiograph (CXR). We hypothesized that a CXR obtained 1 hour after chest tube removal would exclude the presence of a recurrent pneumothorax. METHODS: Of 214 trauma intensive care unit patients with a chest tube during a 1-year period, 75 met entry criteria and underwent chest tube removal according to an institutional review board-approved prospective study protocol. Patients were undergoing positive-pressure ventilation, with an existing solitary chest tube, and had less than 150 mL of drainage on water seal over the previous day. After chest tube removal, serial CXRs were obtained at approximately 1, 10, and 36 hours. Demographic, chest tube, and ventilator data were collected. RESULTS: None of the patients experienced hemodynamic or respiratory deterioration after chest tube removal. There were nine pneumothoraces (12%). All pneumothoraces were present on the initial CXR after chest tube removal. Two patients (3%) required intervention for pneumothorax. Of the remaining seven small pneumothoraces, three resolved and four were unchanged on the third CXR. CONCLUSION: A CXR obtained within 1 to 3 hours after chest tube removal effectively identifies pneumothorax in mechanically ventilated patients.     

Frühe Drainagenentfernung nach videoassistierten thorakoskopischen Operationen

BACKGROUND: Chest tubes frequently cause postoperative patient discomfort after video-assisted thoracoscopic surgery (VATS). Therefore, a prospective randomized study was conducted to analyze whether early chest tube removal within 2 h postoperatively is justified in VATS. METHODS: Ninety-three patients fulfilled the inclusion criteria (VATS including wedge resection, complete lung extension on postoperative chest roentgenogram) and showed no exclusion criteria (lung volume reduction surgery, extensive pulmonary fibrosis, pneumothorax, pleural effusion, air fistula). Randomization resulted in early chest tube removal in 48 patients and in conventional chest tube management in 45 patients. RESULTS: Pain intensity was significantly reduced after early chest tube removal (P=0.03, t-test). In consequence, the mean analgesic requirement was significantly reduced (P=0.0001, t-test). The number of postoperative chest roentgenograms was significantly reduced after early chest tube removal (P=0.0001, t-test). The mean postoperative length of hospital stay was 5.4 vs 6.7 days (P=0.11, t-test). No postoperative complication occurred after early chest tube removal, while postoperative complications were observed in six patients with conventional chest tube management (P=0.01, Fisher's test). CONCLUSION: Early chest tube removal after video-assisted thoracoscopic wedge resection is recommended. The inclusion and exclusion criteria of this study should be considered for future early chest tube removal. Long-term follow-up will clarify if early chest tube removal also leads to a reduction in chronic pain.     

Clinical implications of blood gas analysis of chest tube drainage

Blood gas analysis of chest tube drainage following thoracostomy for experimental and clinical penetrating chest injuries was evaluated to determine its usefulness in predicting the etiology of the injury. Twenty dogs were divided into four groups and sustained right chest injury as follows: Group I--closed chest lung laceration; Group II--open chest lung laceration; Group IIII-gunshot wounds; Group IV--thoracotomy and injection of autologous, mixed venous blood. All animals and 14 patients who sustained penetrating chest injury were made simultaneously from chest tube draininage, systemic artery, and central vein in all dogs and patients. Eight patients (Group A) had pneumothorax; six patients (Group B) did not. Mean control canine aortic PO2 and pulmonary arterial PO2 values in Group I did not differ significantly from those in the other three canine groups, nor from the two human groups. Group II dogs exhibited chest tube PO2 which was significantly (p less than 0.01) above aortic PO2. In Group IV, chest tube PO2 was increased significantly above pulmonary arterial blood. Patients without pneumothorax had values for PO2 in chest tube drainage and aorta which were not significantly different, whereas when pneumothorax was present, PO2 of chest tube drainage was significantly higher than that of aortic PO2. Thus blood gas determinations on chest tube drainage may reflect the nature of the injury; however, the presence of air in the pleural space can result in oxygenation of contained blood well above systemic arterial levels.     

Incidence of chest tube malposition in the critically ill: a prospective computed tomography study

BACKGROUND: Malposition of percutaneously inserted chest tubes is considered as a rare complication in critically ill patients. Its incidence, however, remains uncertain. The aims of the study were to assess the true incidence of chest tube malposition in critically ill patients and to identify predicting factors. METHODS: The authors prospectively studied 122 chest tubes percutaneously inserted in 75 consecutive critically ill patients. For clinical reasons independent of the study, thoracic computed tomography scanning was performed in 63 patients, allowing direct visualization of 106 chest tubes. Based on these findings, chest tube position was classified as intrapleural, intrafissural, or intraparenchymal. Factors predicting chest tube malposition were analyzed by univariate and multivariate analysis. RESULTS: The mean delay between chest tube placement and thoracic scan was 3.5+/-2.9 days. Twenty-two chest tubes were diagnosed as being intrafissural (21%), and 10 were diagnosed as being intraparenchymal (9%). The only predicting factor associated with the risk of malposition was the use of a trocar for the percutaneous insertion of the chest tube (P=0.032). CONCLUSIONS: Malposition was detected in 30% of percutaneously inserted chest tubes, a higher incidence than previously reported. Avoiding the use of a trocar may reduce significantly the incidence of chest tube malposition.     

Chest tube management following pulmonary lobectomy: change of protocol results in fewer air leaks

Much controversy exists regarding the management of chest tubes following pulmonary lobectomy. The objective of this study was to analyse the effect of a new chest tube management protocol on clinical features, such as postoperative air leak, drain characteristics, 30-day postoperative complications and length of hospital stay. We retrospectively analysed 133 patients who underwent pulmonary lobectomy, from January 2005 to December 2008. A new chest tube protocol was introduced on 1 January 2007 and included placement of a single chest tube and early conversion to water seal. The chest tube was removed when air leak had resolved and (non-chylous) fluid drainage was <400 ml/day. The results of patients in the old (n=68) and the new protocol (n=65) were compared. In the new protocol group the median duration of air leak and duration of chest tube drainage declined significantly. Also the length of hospital stay decreased significantly to a median of eight days. The number of reinterventions and 30-day morbidity and mortality rates did not differ significantly. Our data suggest that placement of a single chest tube and early conversion to water seal decreases the duration of air leak and chest tube drainage and length of hospital stay.     

Feasibility of early removal of chest tube in the operating room for spontaneous pneumothorax: A prospective randomized controlled study

Background/ObjectiveChest drainage tube after surgery causes pain and prolonged length of hospital stay. Especially, young patients tend to experience greater postoperative pain than elderly patients. Therefore, we needed to discuss the indication of chest tube placement. The purpose of this study was to demonstrate the safety and advantages of post-operative management without drainage tube placement, by comparing cases with and without drainage tube placement.MethodsPatients who underwent bullectomy for spontaneous pneumothorax were enrolled in this prospective randomized controlled study and randomized into two groups: group with a post-operative chest tube and group without a chest tube. Surgery and post-operative management were performed according to our protocol.ResultsAmong the 42 patients, pneumothorax occurred in 1 patient with a chest tube a day after tube removal. Patients without chest tube had significantly lower post-operative pain (P = 0.107～P < 0.001), despite their reduced use of rescue drugs. The mean length of post-operative hospital stay was 2.5 days in patients with chest tube, which was significantly longer than that of patients without chest tube (1.2 days; P < 0.001).ConclusionsOur patient selection and surgical protocols may be feasible and contribute to post-operative pain control.     

Postoperative chest tube management: snapshot of German diversity

OBJECTIVES The management of chest tubes is one of the most critical aspects in patient care in thoracic surgery, and no consensus exists regarding the ideal chest tube management strategy. METHODS Chest tube management protocols and their effects on chest tube therapy were compared at four German specialist thoracic surgery units. Altogether, 79 patients were stratified for underlying disease and type of surgery. A digital chest drainage system was applied to objectify the presence of air leakages. RESULTS In our analysis, the average length of drainage therapy was 4.9?±?2.8 days. Different chest tube management protocols resulted in a significant degree of scatter between units (P?=?0.0348). Higher arbitrary postoperative suction levels (4?kPa) resulted in earlier chest tube removal than lower suction levels (2?kPa) (4.2?±?2.4 vs 5.4?±?3.0 days, P?=?0.06). Patient discharge following chest tube removal was delayed on average by 3.2?±?2.9 days. This delay was not correlated with the previous duration of chest tube therapy (Spearman's ρ=-0.15, P?=?0.25) in contrast to the total length of hospital stay (ρ?=?0.59, P?相似文献   

Incidence of Chest Tube Malposition in the Critically Ill: A Prospective Computed Tomography Study

Thin chest wall is an independent risk factor for the development of pneumothorax after chest tube removal

The factors contributing to the development of pneumothorax after removal of chest tube thoracostomy are not fully understood. We hypothesized that development of post pull pneumothorax (PPP) after chest tube removal would be significantly lower in those patients with thicker chest walls, due to the "protective" layer of adipose tissue. All patients on our trauma service who underwent chest tube thoracostomy from July 2010 to February 2011 were retrospectively reviewed. Patient age, mechanism of trauma, and chest Abbreviated Injury Scale score were analyzed. Thoracic CTs were reviewed to ascertain chest wall thickness (CW). Thickness was measured at the level of the nipple at the midaxillary line, as perpendicular distance between skin and pleural cavity. Chest X-ray reports from immediately prior and after chest tube removal were reviewed for interval development of PPP. Data are presented as average ± standard deviation. Ninety-one chest tubes were inserted into 81 patients. Patients who died before chest tube removal (n = 11), or those without thoracic CT scans (n = 13) were excluded. PPP occurred in 29.9 per cent of chest tube removals (20/67). When PPP was encountered, repeat chest tube was necessary in 20 per cent of cases (4/20). After univariate analysis, younger age, penetrating mechanism, and thin chest wall were found to be significant risk factors for development of PPP. Chest Abbreviated Injury Scale score was similar in both groups. Logistic regression showed only chest wall thickness to be an independent risk factor for development of PPP.     

Chest tube perforation of esophagus following repair of esophageal atresia

The two major acute thoracic complications of closed chest tube thoracostomy are pulmonary laceration and vascular compression. We have noted that closed chest tube thoracostomy can also perforate an esophageal anastomosis or myotomy site. Clinically, such a perforation produces a profuse discharge of gas and/or fluid through a chest tube positioned at the level of the anastomosis or myotomy site. Plain films demonstrate an accumulation of extrapleural gas and/or fluid adjacent to the distal portion of the chest tube. If untreated, these accumulations may form into an extrapleural abscess.     

Malpositioning of the chest tube across the anterior mediastinum is risky in chronic obstructive pulmonary disease patients with pneumothorax

Malpositioning is one of the most common complications of chest tube insertion and is associated with increased morbidity and mortality. We present two cases of patients with chronic obstructive pulmonary disorder (COPD) in whom malpositioned chest tubes penetrated through the anterior mediastinum to the contralateral pleural cavity, and were later removed without complications. Both patients had a relatively wide retrosternal airspace and received blunt dissection with a trocar for percutaneous chest tube insertion, which may have increased the risk of chest tube penetration through the anterior mediastinum during tube thoracostomy. Further, the precise location of the malpositioned chest tubes could not be confirmed by single-view anteroposterior portable chest radiography, and computed tomography (CT)-scan was more helpful in the diagnosis and management of the cases reported herein.     

The efficacy of X-rays after chest tube removal

BACKGROUND: The insertion and subsequent removal of chest tubes are frequently performed procedures. We hypothesize that routine chest radiographs obtained after chest tube removal to confirm the absence of any post-procedure complications have little impact on clinical management. MATERIALS AND METHODS: A 5-year retrospective study of 73 patients with tube thoracotomies was performed in a level II trauma center's intensive care unit. Patients were identified from billing records for chest tube placement. Medical records and official chest x-ray film reports, both before and after removal, were reviewed, and demographic data were collected. RESULTS: Of the 73 patients examined, only 8 had postprocedure reports that differed from the preprocedure reports. Two of these 8 patients required reinsertion of a chest tube to treat the recurrence of a significant pneumothorax. However, the decision to reinsert the chest tube was based on the patient's clinical appearance rather than on the x-ray findings. CONCLUSION: Chest radiography following the removal of chest tubes should not be a routinely performed procedure, but should preferably be based on the good clinical judgement and discrimination of the surgeon.     

Postoperative Myocardial Ischemia Caused by Chest Tube Compression of Vein Graft

Here we report an unexpected and possibly overlooked cause of postoperative myocardial ischemia: a chest tube compressing a vein graft. After the position of the chest tube was adjusted, graft flow was reestablished, right ventricular contractility returned, and myocardial infarction was probably prevented. The literature on chest tube complications is briefly reviewed and experience from our institution is reported.     

Management of pleural injuries during retroperitoneal surgical procedures

Purpose The necessity of a postoperative chest tube for the treatment of pneumothorax after a radical nephrectomy is controversial. Materials and methods A five-year retrospective study was performed on 91 patients, having undergone a radical nephrectomy. We examined the existence and length of a pleural rent, presence of a postoperative thoracostomy tube, postoperative pneumothorax, postoperative pneumonia, postoperative atelectasis, pain scores, hemoglobin saturation, and length of hospital stay with univariate and multivariate analysis. Results Incidence of a pleural rent occurred in 29 (36%) of open radical nephrectomy cases; 4 of the 29 cases had a postoperative thoracostomy tube. There was no significant difference in hemoglobin saturation levels between cases that had no pleural rent, a pleural rent without a thoracostomy tube, and a pleural rent with a postoperative thoracostomy tube. A pleural rent without a postoperative chest tube had significantly lower rates of pain score, atelectasis, pneumonia, pleural effusion, and length of hospital stay compared to individuals with a postoperative chest tube. Patients with a chest tube had a significantly higher incidence of pain, atelectasis, pneumonia, effusion, and length of hospital stay. Conclusion Iatrogenic pleural rents treated without a postoperative chest tube show a significant decrease in postoperative complications of pneumonia and atelectasis, pain score and length of hospital stay. These patients show no significant increases in postoperative complications; therefore, it appears that postoperative chest tube placement after a pleural injury occurs is of no advantage.     

Omission of routine chest x-ray after chest tube removal is safe in selected trauma patients

Background

Definitive practice guidelines regarding the utility of chest x-ray (CXR) following chest tube removal in trauma patients have not been established. The authors hypothesized that the selective use of CXR following chest tube removal is safe and cost effective.

Methods

A retrospective review of chest tube insertions performed at a level I trauma center was conducted.

Results

Patients who underwent chest tube removal without subsequent CXR had a lower mean Injury Severity Score and were less likely to have suffered penetrating thoracic injuries. These patients received fewer total CXRs and had shorter durations of chest tube therapy and shorter lengths of stay following tube removal. Subsequent reinterventions were performed more frequently in the CXR group. The annual decrease in hospital charges by foregoing a CXR was $16,280.

Conclusions

The selective omission of CXR following chest tube removal in less severely injured, nonventilated patients does not adversely affect outcomes or increase reintervention rates. Avoiding unnecessary routine CXR after chest tube removal could provide a significant reduction in total hospital charges.     

Primary treatment of malignant pleural effusions: video-assisted thoracoscopic surgery poudrage versus tube thoracostomy

The objective of this study is to show that primary treatment of malignant pleural effusions secondary to ovarian carcinoma with video-assisted thoracoscopic surgery (VATS)-assisted talc poudrage (VATS-ATP) results in shorter hospital stays and reduced time with a chest tube than primary treatment with a chest tube and chemical pleurodesis. We conducted a retrospective chart review of all patients with a symptomatic pleural effusion secondary to primary ovarian carcinoma receiving intervention from January 1996 to December 2000. Patients either received tube thoracostomy with pleurodesis (n = 22) or VATS-ATP (n = 12). Of the patients treated with tube thoracostomy 18 per cent (4/21) died in the hospital before pleurodesis, 77 per cent (14/19) had successful pleurodesis, and 22 per cent (4/18) failed pleurodesis requiring VATS-ATP. In the group treated primarily with tube thoracostomy the chest tube was in place 8.36 +/- 2.61 days with a hospital stay of 12.64 +/- 5.80 days after the procedure. In the group treated with VATS-ATP there was 100 per cent successful pleurodesis. There were no mortalities. There was one prolonged intubation of 3 days and one incomplete lung reexpansion. The chest tube was in place for 4.58 +/- 1.78 days and a hospital stay of 7.50 +/- 4.12 days postprocedure. Groups treated by tube thoracostomy and VATS were statistically different; P < 0.001 for days with a chest tube and P = 0.011 for hospital days. We conclude that both tube thoracostomy with chemical pleurodesis and VATS-ATP provide adequate treatment of ovarian carcinoma-associated malignant pleural effusions. VATS-ATP provides a shorter duration of chest tube placement and postprocedure hospital stay.     

Verletzung der V. subclavia mit einer Thoraxdrainage

The necessity for insertion of a thorax drainage can lead to serious complications. Especially the use of a trocar instead of a minithoracotomy has a notable risk of misplacement or complications. Chest tubes per se can perforate the parietal pleura resulting in an extrathoracic position of the tube and contraindications for chest tubes should always be considered. Accidental lacerations of blood vessels should be avoided by a correct technique and a clear indication. A chest X-ray in one plane is not sufficient to prove correct positioning of a chest tube and suspected misplacement of a chest tube has to be assessed radiographically in at least two planes. A case of a fatal complication of a misplaced chest tube causing a laceration of the right subclavian vein is described.     

Initial chest tube management after pulmonary resection

Tube thoracostomy management with suction or water seal after anatomical pulmonary resection remains somewhat controversial. Initial chest tube management may influence the duration of pleural fluid drainage, duration of tube thoracostomy, and/or hospital length of stay following pulmonary resection. We hypothesized that initial chest tube management with water seal decreases time for chest tube removal and decreases time of hospital stay. A retrospective chart review was performed on 109 consecutive patients who underwent lobectomy or segmentectomy in Western Pennsylvania Hospital between December 1999 and December 2003. Comparison was made between chest tube management of water seal or suction in patients with and without air leak. Of the 109 patients, 78 (72%) had no air leak at the completion of surgery, and 31 (28%) had air leak. In the group without air leak (n = 78), water seal was used in 32 (41%) patients and suction in 46 (59%). In patients placed to water seal initially after surgery (n = 32), removal of chest tubes was on postoperative day (POD) 3.19 +/- 0.24 and hospital discharge was on POD 5.13 +/- 0.61. In patients placed to suction initially (n = 46), chest tubes were removed on POD 4.52 +/- 0.40. Hospital discharge was on POD 6.74 +/- 0.5. Both duration of chest tube (P < 0.007) and length of hospital stay (P < 0.04) were significantly lower in the water seal group. In the air leak group (n = 31), 7 (23%) patients were managed with water seal and 24 (77%) patients with suction. Both duration of chest tube (P = 0.001) and length of hospital stay (P < 0.05) were significantly lower in the water seal group. In patients without air leak, chest tubes should be managed with water seal following anatomical pulmonary resection, resulting in significantly shorter chest tube duration and hospital length of stay.     

Avoiding chest tube placement after video-assisted thoracoscopic wedge resection of the lung.

OBJECTIVE: A chest tube is usually placed in the pleural cavity after wedge resection of the lung, even after thoracoscopic procedures. The aim of this study was to determine the validity and safety of postoperative management without chest tube placement for patients undergoing thoracoscopic wedge resection of the lung. METHODS: Between 1998 and 2002, 93 patients underwent thoracoscopic wedge resection of the lung. In January 2000, we established the following criteria for avoiding chest tube placement: (1) absence of air leaks during intraoperative alternative sealing test, (2) absence of bullous or emphysematous changes on inspection, (3) absence of severe pleural adhesions, and (4) absence of prolonged pleural effusion requiring chest drainage preoperatively. Seventeen of 93 patients did not satisfy the criteria. The other 76 patients were divided into two groups: group 1 consisted of 34 patients who underwent thoracoscopic resection before 1999 and in whom a chest tube was routinely placed in spite of retrospectively meeting the criteria, group 2 consisted of 42 patients who underwent thoracoscopic resection after 2000 and in whom chest tube was not placed. The clinical data were evaluated and analyzed between the two groups. RESULTS: Two patients in group 1 required new intervention after removal of a chest tube that had been inserted during the operation due to recurrence of a pneumothorax, so did two patients in group 2 after the operation. The rate of late pneumothorax requiring intervention is similar in groups 1 and 2. No differences were found between the two groups with regard to postoperative chest pain and hospital stay. No patients experienced a significant adverse outcome. CONCLUSIONS: Avoiding the chest tube placement did not increase postoperative morbidity if carefully selected criteria are met.     

Initial suction evacuation of traumatic hemothoraces: a novel approach to decreasing chest tube duration and complications

Between 2 and 4.4 per cent of all patients with trauma chest tubes develop retained hemothoraces. Retained hemothoraces prolong chest tube duration and hospital length of stay, and increase infectious complications like empyema. Early surgical drainage of retained hemothoraces has been shown to decrease complications and reduce hospital length of stay. However, the high resource and expertise requirement may limit the widespread applicability of surgical drainage. We present the results of a relatively simple and novel intervention for traumatic hemothoraces undertaken by our faculty to shorten chest tube duration and prevent empyema formation. At our Level I trauma center, 10 trauma patients underwent initial suction evacuation of their traumatic hemothoraces using a sterile suction catheter before chest tube placement. Compared with propensity matched controls, patients that underwent initial suction evacuation experienced significantly shorter chest tube duration (4.2 ± 1.9 vs 5.8 ± 2.3 days, P = 0.04). Also, in this population, there was an 8.2 per cent decrease in the number of patients that developed empyema or required additional drainage. Our study suggests that initial suction evacuation of traumatic hemothoraces is an effective and relatively easy intervention that reduces the duration of chest tube therapy, empyema formation, and the need for additional surgical intervention.
