Complications of tube thoracostomy for acute trauma

Closed tube thoracostomy is a common and very useful procedure in therapy of acute thoracic injury. However, it is not without risk. With aggressive use of this procedure in the emergency department, the incidence of technical complications was 1 percent. Our review suggests that complications can be further diminished by the routine use of large thoracostomy tubes that are placed well up on the chest after confirmation of an open pleural space, by avoiding the use of a trocar for tube placement, and by the use of a high volume, low pressure suction system. Empyema was the most common complication associated with tube thoracostomy after trauma. It occurred in 2.4 percent of the patients. Its exact cause is not known, and the role of prophylactic antibiotics needs to be established.     

Complications following blunt and penetrating injuries in 216 victims of chest trauma requiring tube thoracostomy

Tube thoracostomy (TT) is required in the treatment of many blunt and penetrating injuries of the chest. In addition to complications from the injuries, TT may contribute to morbidity by introducing microorganisms into the pleural space or by incomplete lung expansion and evacuation of pleural blood. We have attempted to assess the impact of TT following penetrating and blunt thoracic trauma by examining a consecutive series of 216 patients seen at two urban trauma centers with such injuries who required TT over a 30-month period. Ninety-four patients suffered blunt chest trauma; 122 patients were victims of penetrating wounds. Patients with blunt injuries had longer ventilator requirements (12.6 +/- 14 days vs. 3.7 +/- 7.1 days, p = 0.003), longer intensive care stays (12.2 +/- 12.5 days vs. 4.1 +/- 7.5 days, p = 0.001), and longer periods of TT, (6.5 +/- 4.9 days vs. 5.2 +/- 4.5 days, p = 0.018). Empyema occurred in six patients (3%). Residual hemothorax was found in 39 patients (18%), seven of whom required decortication. Recurrent pneumothorax developed in 51 patients (24%) and ten required repeat TT. Complications occurred in 78 patients (36%). Patients with blunt trauma experienced more complications (44%) than those with penetrating wounds (30%) (p = 0.04). However, only seven of 13 patients developing empyema or requiring decortication had blunt trauma. Despite longer requirements for mechanical ventilation, intensive care, and intubation, victims of blunt trauma seemed to have effective drainage of their pleural space by TT without increased risk of infectious complications.     

Empyema thoracis in patients undergoing emergent closed tube thoracostomy for thoracic trauma

The vast majority of thoracic trauma victims require only observation or tube thoracostomy for definitive treatment of their thoracic injury. Although tube thoracostomy is generally considered a limited intervention, 2 to 25 percent of patients who undergo this procedure develop infectious complications. To determine the incidence and risk factors for the development of empyema thoracis after tube thoracostomy, a retrospective study was undertaken. We found that the development of empyema thoracis was increased in patients whose pleural space was incompletely drained and whose thoracic catheters were in place for a prolonged period.     

Morbidity of percutaneous tube thoracostomy in trauma patients.

OBJECTIVES: This prospective study was designed to evaluate the complications of percutaneous tube thoracostomy (PTT) performed for chest trauma in our institution and to determine predictive factors. METHODS: One hundred and thirty-four primary PTTs were performed in 128 patients for blunt (83) and penetrating (45) chest traumas. Failure was defined as undrained hemothorax or pneumothorax, post-tube removal complications and empyema. Univariate and multivariate hazard analyses were used to assess the association between potential risk factors and complications. RESULTS: The overall complication rate was 25% including 30 (23%) failures and nine (7%) improper placement with iatrogenic injuries to the lung (n = 4) or subclavian vein (n = 1). Complications were managed with 18 repeat PTTs and ten early thoracotomies for clotted hemothorax (two), persistent air leak (two), fluid collection (three) or a combination (three) at a mean delay of 6.5 +/- 2.4 days. Failure of additional PTT required late decortication for empyema (three) or decortication (three) at a mean delay of 23 +/- 7 days. One patient died postoperatively, the only death directly related to PTT failure among the four (3.1%) deaths that occurred in this study. Hospital length of stay was significantly increased in patients with PTT failure (24 +/- 19 vs. 15 +/- 8 days in uncomplicated PTT, P = 0.004). By univariate analysis, polytraumatism (relative risk (RR) 2.7, P < 0.05), the need for assisted ventilation (RR 2.7, P = 0.003) and tube insertion by emergency physicians (RR 8.7, P < 0.0001) were significantly associated with increased incidence of complications in blunt trauma. Multivariate analysis identified the performance of the procedure by operators other than thoracic surgeons and residents trained in thoracic surgery as the only independent risk factor in both blunt and penetrating trauma (RR 58 and 71, respectively, P < 0.00001). CONCLUSIONS: PTT is associated with significant morbidity and extended hospitalizations, partly related to inappropriate training of all individuals dealing with trauma care. Additional training should be recommended and some conventional indications for PTT should be revised. A prospective study is currently in progress to evaluate the benefit of early videothoracoscopy in trauma and failure of primary PTT.     

Rapid atrial fibrillation following tube thoracostomy insertion.

We report a case of trauma patient, whose heart rhythm and rate changed from sinus tachycardia to rapid atrial fibrillation. The change occurred immediately after the insertion of left thoracostomy tube. The patient did not respond to pharmacological treatment. Only when the tube was pulled out, the rhythm returned to sinus. Chest radiogram shows the position of the tube, in close proximity to the cardiac silhouette.     

A thoracostomy tube guideline improves management efficiency in trauma patients

BACKGROUND: Thoracostomy tube (TT) placement constitutes primary treatment for traumatic hemopneumothorax. Practice patterns vary widely, and criteria for management and removal remain poorly defined. In this cohort study, we examined the impact of implementation of a practice guideline (PG) on improving management efficiency of thoracostomy tube. METHODS: We developed a PG aimed at standardizing the management of TTs in critically ill patients admitted to a Level I trauma center. During the 9-month period before (Pre-PG) and 3 months after (Post-PG) implementation, practice parameters including prophylactic antibiotics, duration of TT therapy, preremoval chest radiographs with associated charges, and complications were evaluated. Differences between groups were assessed by Mann-Whitney rank sum and chi(2) with Yates correction. RESULTS: There were 61 patients, 14 in the Pre-PG group and 47 in the Post-PG group. The groups were matched in age and Injury Severity Scores. The Post-PG cohort averaged 3 fewer days of TT therapy. After implementation of the PG, 21 patients did not have preremoval chest radiography, representing a $3000 reduction in radiology fees. Complication rates (retained pneumothorax, hemothorax, and empyema) were not different between the two groups. CONCLUSION: Implementation of a thoracostomy tube practice guideline was associated with improved management efficiency in trauma patients.     

Complications following talus trauma

The injuries of the talus are rare. In this retrospective study, complications of 359 talar lesions are studied. Secondary displacement occurred in 8%. Bone infection remained low in spite of frequent primary skin injury (20%). Bone fusion was slow but no case of non-union could be found. Avascular necrosis of the body or of the trochlea occurred in 33% but could be partially prevented by accurate reduction of the fractured bone. Osteoarthritis occurred in 33%.     

Ultrasound may safely replace chest radiograph after tube thoracostomy removal in trauma patients

IntroductionA chest radiograph (CXR) is routinely obtained in trauma patients following tube thoracostomy (TT) removal to assess for residual pneumothorax (PTX). New literature supports the deference of a radiograph after routine removal procedure. However, many surgeons have hesitated to adopt this practice due to concern for patient welfare and medicolegal implications. Ultrasound (US) is a portable imaging modality which may be performed rapidly, without radiation exposure, and at minimal cost. We hypothesized that transitioning from CXR to US following TT removal in trauma patients would prove safe and provide superior detection of residual PTX.Materials and MethodsA practice management guideline was established calling for the performance of a CXR and bedside US 2 h after TT removal in all adult trauma patients diagnosed with PTX at a level 1 trauma center. Surgical interns completed a 30-minute, US training course utilizing a handheld US device. US findings were interpreted and documented by the surgical interns. CXRs were interpreted by staff radiologists blinded to US findings. Data was retrospectively collected and analyzed.ResultsEighty-nine patients met inclusion criteria. Thirteen (15%) post removal PTX were identified on both US and CXR. An additional 11 (12%) PTX were identified on CXR, and 5 (6%) were identified via US, for a total of 29 PTX (33%). One patient required re-intervention; the recurrent PTX was detected by both US and CXR. For all patients, using CXR as the standard, US displayed a sensitivity of 54.2%, specificity of 92.3%, negative predictive value of 84.5%, and positive predictive value of 72.2%. The cost of care for the study cohort may have been reduced over $9,000 should US alone have been employed.ConclusionBedside US may be an acceptable alternative to CXR to assess for recurrent PTX following trauma TT removal.     

Advances in thoracostomy tube management

This article summarizes several of the studies utilizing randomized trials or predetermined algorithms for chest tube management. The classification system, when to use wall suction, when to use water seal, and how to safely discharge patients by the fourth postoperative day-even with air leaks-are outlined.     

Acute lung failure following thoracic trauma

Pulmonary failure is almost always present in the early or late phase of multiple organ failure (MOF). Acute lung failure (ALF) is a uniquely constant response to direct or indirect insults to the lung. Increased pulmonary microvascular permeability (PMVP) is associated with the onset of lung permeability edema, the hallmark of ALF. The sequence of PMVP and the development of ALF caused by direct insults are studied. METHODS. A series of 255 trauma patients admitted to our intensive care unit (ICU) from 1987 to 1988 were enrolled in this prospective study. ALF was defined as stage III of the Posttraumatic Pulmonary Insufficiency Score; sepsis syndrome, according to Montgomery; organ failure, as stage II of the MOF score, and MOF was recorded when at least two organs had failed. Thoracic injury and aspiration were expected as direct, sepsis and shock alone as indirect insults to the lung. A computerized large field of view gamma camera was used to measure PMVP simultaneously over both lungs by means of 113mIn-transferrin and 99mTc-erythrocytes. The pulmonary microvascular permeability index (PMVPI; %/h) was used to quantify PMVP in the dynamic scintigraphic measurement. RESULTS. Of the 255 trauma patients (ISS = 33.9 +/- 18.7), 21% (52) patients (ISS = 41 +/- 17.8) developed ALF. 50 (or 96%) of the ALF patients developed MOF in addition, and 27 (72%) of the patients with directly induced ALF developed sepsis syndrome later. Direct lung injury was present in 77% (37) of the patients with posttraumatic ALF. Thoracic injury was the main cause of ALF: 58% (30) of 52 patients with ALF had a thoracic injury, which was true of only 30% of the non-ALF group (P less than 0.05). 33 (or 89%) of the ALF patients with direct injury developed ALF less than 72 h after injury (early ALF), and only 11% (4) later than 72 h after injury (late ALF). Indirect injury of the lung was present in 22% (12) of the patients with posttraumatic ALF. Indirectly induced ALF occurred in less than 72 h in 36% (4) and more than 72 h after injury in 64% (7) trauma patients. PMVP was determined in 21 of the 30 patients with thoracic injury. Initial evaluation of these patients with direct induced ALF showed significantly elevated (P less than 0.01) PMVP for the traumatized (PMVPI = 10.8 +/- 5.1%/h) but normal values for the nontraumatized lung (PMVPI = 3.9 +/- 3.4%/h), whereas 4 days later the PMVP increased significantly (P less than 0.05) on the primarily healthy side (PMVPI = 8.0 +/- 5.0%/h) while remaining elevated for the traumatized lung (PMVPI = 10.9 +/- 6.0%/h). In the control group the PMVPI was 2.6 +/- 2.8%/h for the right and 2.0 +/- 2.8%/h for the left lung. Similar values were found in mechanically ventilated ICU patients without ALF. DISCUSSION. Direct injury seems to be the dominant mechanism for early manifestation (less than 72 h) of posttraumatic ALF. The thoracic trauma seems to damage the pulmonary endothelium directly, thus increasing PMVP in a circumscribed region. An overwhelming inflammatory response may cause the later increase in PMVP in the primarily healthy lung areas.     

Prophylactic antibiotics for the prevention of infectious complications including empyema following tube thoracostomy for trauma: results of meta-analysis.

Since 1977, six clinical trials have been performed on the subject of routine antibiotic prophylaxis in patients requiring tube thoracostomy for trauma. No definitive conclusions have been reached regarding the efficacy of antibiotic use in this setting. The results of these clinical trials were pooled to generate an unbiased estimate of the efficacy of antibiotic prophylaxis for tube thoracostomy using the technique of meta-analysis. Meta-analysis is a statistical method for synthesizing results from separate but similar experiments, grouping them, and comparing each to the null hypothesis. Meta-analysis allows synthesis of all of the available data on antibiotic prophylaxis for tube thoracostomy to resolve the controversy surrounding this issue generated by different but similar clinical studies with conflicting results. Despite different conclusions of value when taken individually, the combined analysis does not support the null hypothesis (no effect of antibiotics). The statistical method is highly significant despite different mechanisms of injury, pathologic findings, and antibiotics employed.     

Complications following gastric tube esophagoplasty in children

Surgery in children with caustic esophageal burns, esophageal atresia or other esophageal disorders can be performed using gastric tube esophagoplasty. Between 1991 and 1999, a number of 41 such procedures have been performed in our department, using the original technique developed by Gavriliu. The results were assessed as good and very good in 83% of the cases, and fair or bad in the rest of 17%. We recorded 13 cases with significant complications, 4 of which ended with exitus. The paper present our experience in using gastric tube esophagoplasty and the management of the complications related to this procedure.     

Analgesia for pediatric thoracostomy tube removal

Eutectic mixture of local anesthetics (EMLA; Astra Pharmaceuticals, Wayne, PA) has been shown to reduce the pain of blood draws in children. We investigated the use of EMLA versus IV morphine for providing analgesia during chest tube removal (CTR) in children. One hundred twenty pediatric cardiothoracic surgery patients were enrolled. Patients were randomly assigned to receive either morphine (0.1 mg/kg up to 10 mg IV 30 min before CTR) or EMLA cream (5 g per chest tube cutaneously 3 h before CTR). A single, trained observer rated the patient's pain before, during, and after CTR using a 10-cm visual analog scale. The sites were evaluated for adverse effect. Methylhemoglobin levels were monitored in infants. Before CTR, the pain scores of the children who received morphine were rated lower than those who received EMLA (P < 0.01). During CTR, there was no difference in the pain score between the morphine or EMLA group. The change from baseline pain score in the morphine group was significantly larger than in the EMLA group (P < 0.01). We conclude that EMLA is safe and useful for blunting the pain of CTR.
