Thoracic Ultrasound for Detection of Pneumothorax Following Thoracostomy Tube Removal in Trauma Patients.

INTRODUCTION: Screening for pneumothorax (PTX) is standard practice after thoracostomy tube removal, with postpull CXR being the gold standard. However, studies have shown that point-of-care thoracic ultrasound (POCTUS) is effective at detecting PTX and may represent a viable alternative. This study aims to evaluate the safety and efficacy of POCTUS for evaluation of clinically significant postpull PTX compared with chest x-ray (CXR). METHODS: We performed a prospective, cohort study at a Level 1 trauma center between April and December 2022 comparing the ability of POCTUS to detect clinically significant postpull PTX compared with CXR. Patients with thoracostomy tube placed for PTX, hemothorax, or hemopneumothorax were included. Clinically insignificant PTX was defined as a small residual or apical PTX without associated respiratory symptoms or need for thoracostomy tube replacement while clinically significant PTX were moderate to large or associated with physiologic change. RESULTS: We included 82 patients, the most common etiology was blunt trauma (n = 57), and the indications for thoracostomy tube placement were: PTX (n = 38), hemothorax (n = 15), and hemopneumothorax (n = 14). One patient required thoracostomy tube replacement for recurrent PTX identified by both ultrasound and X-ray. Thoracic ultrasound had a sensitivity of 100%, specificity of 95%, positive predictive value of 60%, and negative predictive value of 100% for the detection of clinically significant postpull PTX. CONCLUSIONS: The use of POCTUS for the detection of clinically significant PTX after thoracostomy tube removal is a safe and effective alternative to standard CXR. This echoes similar studies and emphasizes the need for further investigation in a multicenter study.

A Novel Technique for Temporally Securing a Chest Tube in a Resource-Limited Environment.

In the prehospital, transport, and resource-limited setting, patients with traumatic hemothorax, pneumothorax, or cardiac arrest require emergency tube thoracostomy for stabilization and transport. With the possibility of multiple patients, limited providers, and inability to commit a 1:1 provider-to-patient ratio for safe tubeless thoracostomies, a chest tube is often the safest option. Mercy Health Life Flight Air Medical program has developed practice over decades using towel clamps and tape to achieve securement rapidly and reliably. We report on this subject as an option for temporarily securing a chest tube in the disaster, resource-poor, prehospital, or critical care transport setting.

Needlessly Treated: Evaluation of Prehospital Needle Thoracostomy.

BACKGROUND: Needle thoracostomy is a potentially life-saving intervention for tension pneumothorax but may be overused, potentially leading to unnecessary morbidity. OBJECTIVE: To review prehospital needle thoracostomy indications, effectiveness, and adverse outcomes. METHODS: A retrospective cohort study was conducted based on registry data for a United States Midwestern Level I trauma center for a 7.5-year period (January 2015 to May 2022). Included were patients who received prehospital needle thoracostomy and trauma activation before hospital arrival. The primary outcomes were correct indications and improvement in vital signs. Secondary outcomes were the need for chest tubes, correct needle placement, complications, and survival. RESULTS: A total of n = 67 patients were reviewed, of which n = 63 (94%) received a prehospital thoracostomy. Of the 63 prehospital thoracostomies, 54 (86%) survived to arrival. Of these 54, 44 (n = 81%) had documented reduced/absent breath sounds, 15 (28%) hypotension, and 19 (35%) with difficulty breathing/ventilating. Only four patients met all three prehospital trauma life support criteria: hypotension, difficulty ventilating, and absent breath sounds. There were no significant changes in prehospital vitals before and after receiving needle thoracostomy. In patients receiving imaging (n = 54), there was evidence of 15 (28%) lung lacerations, 6 (11%) of which had a pneumothorax and 3 (5%) near misses of important structures. Review of needle catheters visible on computer tomography imaging found 11 outside the chest and 1 in the abdominal cavity. CONCLUSION: The study presents evidence of potential needle thoracostomy overuse and morbidity. Adherence to specific guidelines for needle decompression is needed.

Development and evolution of a robotic surgical technique for the treatment of thoracic outlet syndrome.

OBJECTIVE: We describe the development and evolution of a surgical technique that uses the robotic da Vinci Surgical System (Intuitive Surgical, Inc, Sunnyvale, Calif) for the transaxillary approach to repair the disabling thoracic outlet syndrome (TOS). We report our patient outcomes associated with the use of this robotic technique. METHODS: We present a retrospective review and analysis of data collected from a 16-year experience of a single surgeon using a robotic surgical system and technique for TOS surgery. From the initial design of an endoscope attached to a microvideo camera in 1982 to the adoption of the monorobotic arm with integrated voice in 1998, the main objective of the transaxillary approach has always been to improve visualization of congenital cervical anomalies of the scalene muscles. From February 2003 to December 2018, we performed 412 transaxillary decompression procedures using the robotic da Vinci Surgical System. The surgical procedure has been described in further detail and includes the following steps: (1) positioning of the patient into a lateral decubitus position and using a monoarm retractor; (2) creation of a mini-incision in the axillary area and creation and maintenance of the subpectoral anatomic working space; (3) placement of endoscopic ports and engagement of the robotic instrumentation; (4) dissection of extrapleural and intrapleural soft tissue; (5) creation of the "floater" first rib; (6) excision of the cervical bands and first rib; and (7) placement of thoracostomy tubes for drainage and closure of the incisions. RESULTS: None of the patients died, and no patient experienced permanent neurovascular damage of the extremity. Of the 306 patients, 22 (5% of 441 operations) experienced complications. One patient developed postoperative scarring that required a redo operation with a robotic-assisted transaxillary approach. CONCLUSIONS: With its three-dimensional visual magnification of the anatomic area, the endoscopic robotic-assisted transaxillary approach offers safe and effective management of disabling TOS symptoms. The endoscope facilitates observation of the cervical bands and the mechanism (pathogenesis) of the neurovascular compression that causes TOS, thereby allowing complete excision of the first rib, cervical bands, and scalene muscle. We sought to develop and perfect this robotic approach. The present study was not intended to be a comparative study to nonrobotic TOS surgery.

Too Big, Too Small or Just Right? Why the 28 French Chest Tube Is the Best Size.

BACKGROUND: Tube thoracostomy is a commonly performed procedure in trauma patients. The optimal chest tube size is unknown. This study measures chest tube drainage in a controlled laboratory setting and compares measured flowrates to those predicted by the Hagen-Poiseuille equation. MATERIALS AND METHODS: A model of massive hemothorax was created, consisting of a basin containing synthetic blood substitute (aqueous Glycerin and Xanthan gum) and a standard pleur-evac setup at -20 cm H2O suction. Flow measurements were calculated by measuring the time to drain 2L of blood substitute from the basin. Chest tube sizes tested were 20F, 24F, 28F, 32F, and 36F. Thoracostomy opening was modeled using custom built device that represents two ribs, with the distance between varied 2 to 12 mm. Flowrate increases were compared against predicted increases according to the Hagen-Poiseuille equation. Percent of predicted increase was calculated, both incremental increase and using 20F tube benchmark. RESULTS: All tubes were occluded at a 2 mm thoracostomy opening. At 3 mm, 32F and 36F were occluded while smaller tubes were patent. Tubes 28F and larger exhibited high speed and consistent flowrates, even after decreasing thoracostomy opening down to 7 mm, while flowrates rapidly decreased at opening smaller than 7 mm. Smaller 24F and 20F tubes exhibited highly variable flowrates through the system. Maximum flowrates were 21.7, 36.8, 49.6, 55.6, and 61.0 mL/s for 20F-36F tubes, respectively. The incremental increase in flow ratio for increasing chest tube size was 1.69 (20F to 24F), 1.35 (24F to 28F), 1.12 (28F to 32F), and 1.10 (32F to 36F). CONCLUSIONS: The 28F chest tube exhibited high and consistent velocity, while smaller tubes were slower and more variable. Larger tubes offered only slightly higher flowrates. The 28F is a good balance of reasonable size and high flowrate and is likely the optimal size for most clinical applications.

Chest Tube Insertion Among Surgical and Nonsurgical Trainees: How Skilled Are Our Residents?

BACKGROUND: Competency-based medical education has renewed focus on the attainment and evaluation of resident skill. Proper evaluation is crucial to inform educational interventions and identify residents in need of increased training and supervision. Currently, there is a paucity of studies rigorously evaluating resident chest tube insertion skill. MATERIALS AND METHODS: Residents of all training levels before their intensive care unit rotation or currently rotating through the intensive care unit were invited to participate. Trainees inserted a thoracostomy tube on a high-fidelity simulator. Their performances were recorded and scored by blinded raters using the validated TUBE-iCOMPT rubric. Surgical and nonsurgical residents were compared. RESULTS: Forty-nine residents participated; 30 from nonsurgical and 19 from surgical training programs. Overall, trainees were most deficient in the "preprocedural checks" and "patient positioning and local anesthetic" domains. Surgical trainees demonstrated higher chest tube insertion skill than their nonsurgical peers (median total score 88 [interquartile range, 74-90] versus 75 [interquartile range, 66-85], respectively, P = 0.01), particularly in the "patient positioning" and "blunt dissection" domains (P = 0.01 and P = 0.03, respectively). These differences were no longer significant when controlled for experience and Advanced Trauma Life Support certification. CONCLUSIONS: Overall, surgical residents were more skilled than nonsurgical residents in tube thoracostomy placement. Relative skill deficits within the domains of chest tube insertion have also been identified among residents of different specialties. These areas can be targeted with educational interventions to improve resident performance, and ultimately, patient safety.

The Evolution of Surgical Management for Children and Young Adults With Spontaneous Pneumothorax.

BACKGROUND: Few studies have analyzed pediatric spontaneous pneumothorax (SPTX) nationally. We sought to better define this patient population and explore the evolution of surgical management. METHODS: Patients (10-20 y old) with an International Classification of Diseases, Ninth Revision diagnosis of SPTX were identified within the Kids' Inpatient Database for the years 2006, 2009, and 2012. Diagnoses and procedures were analyzed by International Classification of Diseases, Ninth Revision codes. National estimates were obtained using case weighting. RESULTS: There were 11,792 pediatric SPTX hospitalizations, and patients were predominantly male (84.0%), non-Hispanic white (69.0%), with a mean age of 17.2 y (95% confidence interval, 17.2-17.3). Overall, 52.5% underwent tube thoracostomy as the primary intervention, and more than one-third had a major surgical procedure (34.9%). From 2006 to 2012, there was an increase in bleb excisions from 81.1% to 86.9% and an increase in mechanical pleurodesis from 64.2% to 69.0%. There was a significant change from a predominantly open thoracotomy approach in 2006 (76.1%) to a video-assisted thoracoscopic approach in 2012 (89.3%). CONCLUSIONS: Pediatric admission for SPTX results in tube thoracostomy in more than half of the cases and surgery in approximately one-third of the cases. Surgical intervention has changed to a more minimally invasive approach during the last decade, and counseling to patients and their families should reflect these updated management strategies. LEVEL OF EVIDENCE: III.

Effectiveness and safety of small-bore tube thoracostomy (≤20 Fr) for chest trauma patients: A retrospective observational study.

INTRODUCTION: Tube thoracostomy is an important treatment for traumatic hemothorax and pneumothorax. The optimal tube diameter remains unclear. To reduce invasiveness, we use small-bore chest tubes (≤20 Fr) for all trauma patients for whom tube thoracostomy is indicated in our emergency department (ED). The aim of this study was to investigate the effectiveness and safety of small-bore tube thoracostomy for traumatic hemothorax or pneumothorax. METHOD: We conducted a retrospective observational study at a single emergency medical center. This study included adult patients (≥18 years old) who had undergone tube thoracostomy for chest trauma in the ED during the 5 years from October 2013 to September 2018. We used 20 Fr chest tubes or 8 Fr pigtail catheters. The examined outcome was tube-related complications, such as tube obstruction, retained hemothorax, and unresolved pneumothorax. RESULTS: A total of 107 tube thoracostomies were performed in 102 patients. The mean Injury Severity Score of these patients was 17.8 (±9.6), and the mean duration of the tube placement period was 3.9 days (±1.8). Eight patients developed tube-related complications (7.8%) (retained hemothorax: 4 patients (3.9%), unresolved pneumothorax: 4 patients (3.9%)). None of these cases were caused by tube obstruction. Although the drainage itself was effective, they underwent definitive invasive interventions to stop bleeding or air leak. CONCLUSION: Our study showed that the use of small-bore (≤20 Fr) chest tubes to treat traumatic hemothorax/pneumothorax achieved the purposes of tube thoracostomy. It might be possible to safely manage chest trauma with small-bore chest tubes.

Evaluation of Jackson-Pratt Thoracostomy Drains Compared with Traditional Trocar Type and Guidewire-Inserted Thoracostomy Drains.

A restrospective study was performed to evaluate the efficacy of and complications among Jackson-Pratt (JP) drains placed as thoracostomy drains, traditional trocar type (TRO) thoracostomy drains, and guidewire (GW)-inserted thoracostomy drains that were placed in open fashion during thoracotomy. Medical records of 65 canine and feline patients who underwent thoracic surgery were evaluated. Dogs and cats who underwent thoracotomy and had a chest drain placed intraoperatively were included. Data retrieved from medical records included signalment, body weight, diagnosis, surgical approach, surgical procedure, type of thoracostomy drain, postoperative analgesia, duration of thoracostomy drain, and postoperative complications. The incidence of complications and number of medications used in pain protocols were compared among types of thoracostomy drains. JP (n = 31), TRO (n = 25), and GW (n = 9) thoracostomy drains were placed in 65 patients. Ten minor (15.3%) and four major (6.2%) complications occurred. Cases with JP thoracostomy drains were significantly less likely to have complications (2 minor, 1 major) than cases with TRO thoracostomy drains (8 minor, 3 major, P = .009). There were no differences in the number of major complications when comparing all three drains individually (P = .350). JP drains and GW drains can be considered as an alternative to traditional TRO thoracostomy drains.

Cryptococcal empyema treated with tube thoracostomy and intrapleural fibrinolysis.

A 55-year old woman with a history of relapsed T-cell ALL presented with right pleuritic chest pain and decreased breath sounds over the right hemithorax. Imaging of the chest showed loculated effusions. Tube thoracostomy was performed with intrapleural application of alteplase and dornase alpha over a 3-day period. Repeat imaging demonstrated a marked decrease in the volume of the effusion. In most prior published cases of pleural cryptococcosis, surgical drainage was required in addition to prolonged antifungal agents. More than 50% of patients with cryptococcal infection have severe underlying disease or immunodeficiency state making them high risk for surgery. This is the first case to our knowledge of cryptococcal empyema successfully treated with tube thoracostomy and intrapleural fibrinolysis.

Chest Tube Management Practices by Trauma Surgeons.

BACKGROUND: Chest tube (CT) placement is among the most common procedures performed by trauma surgeons; evidence guiding CT management is limited and tends toward thoracic surgery patients. The study goal was to identify current CT management practices among trauma providers. MATERIALS AND METHODS: We designed a Web-based multiple-choice survey to assess CT management practices of trauma providers who were active, senior, or provisional members (n = 1890) of the Eastern Association for the Surgery of Trauma and distributed via e-mail. Descriptive statistics were used. RESULTS: The response rate was 39% (n = 734). Ninety-one percent of respondents were attending surgeons, the remainder fellows or residents. Regarding experience, 36% of respondents had five or fewer years of practice, 54% 10 y or fewer, and 79% 20 y or fewer. Attendings were more likely than trainees to place pigtail catheters for stable patients with pneumothorax (PTX). Attendings with experience of <5 y were more likely to choose a pigtail than more experienced surgeons for elderly patients with PTX. Respondents preferred standard size CTs for hemothorax and unstable patients with PTX, and larger tubes for unstable patients with hemothorax. Most respondents (53%) perceived the quality of evidence for trauma CT management to be low and cited personal experience and training as the main factors driving their practice. CONCLUSIONS: Trauma CT management is variable and nonstandardized, depending mostly on clinician training and personal experience. Few surgeons identify their practice as evidence based. We offer compelling justification for the need for trauma CT management research to determine best practices.

Appropriate Needle Length for Emergent Pediatric Needle Thoracostomy Utilizing Computed Tomography.

Objective: Needle thoracostomy is a life-saving procedure. Advanced Trauma Life Support guidelines recommend insertion of a 5 cm, 14-gauge needle for pneumothorax decompression. High-risk complications can arise if utilizing an inappropriate needle size. No study exist evaluating appropriate needle length in pediatric patients. Utilizing computed tomography (CT), we determined the needle length required to access the pleural cavity in children matched to Broselow™ Pediatric Emergency Tape color. Methods: Three investigators reviewed chest CTs of children <13 years of age obtained between 2010 and 2015. Patient exclusions included those with a chest wall mass, muscle disease, pectus deformity, anasarca, prior open thoracotomy, inadequate imaging, or missing height documentation. We established 4 groups based upon Broselow™ color as determined by recorded height. Investigators, trained by a pediatric board-certified radiologist, obtained standardized CT measurements of chest wall thickness at 4 points: right/left second intercostal space at the midclavicular line (ICS-MCL) and right/left fourth intercostal space in the anterior axillary line (ICS-AAL). Our outcome was the median chest wall thickness and 95% confidence intervals for each Broselow grouping and anatomic site. Results: A total of 273 chest CTs were reviewed, of which 23 were excluded, for a resultant study population of 250 scans and 498 total measurements. Median patient age was 4 years, 52.8% were male. Children measuring Broselow Gray/Pink (<68 cm), had a median chest wall thickness at the 2nd ICS-MCL of 1.57 cm (95% CI 1.42 cm, 1.72 cm), 4th ICS-AAL 1.67 cm (95% CI 1.48 cm, 1.86 cm). Broselow Red/Purple (68.1-90 cm): 2nd ICS-MCL of 1.96 cm (95% CI 1.84 cm, 2.08 cm), 4th ICS-AAL 1.73 cm (95% CI 1.62 cm, 1.84 cm). Broselow Yellow/White (90.1-115cm): 2nd ICS-MCL of 2.12 cm (95% CI 2.03 cm, 1.22 cm), 4th ICS-AAL 1.91 cm (95% CI 1.8 cm, 2.01 cm). Broselow Blue/Orange/Green (>115.1 cm): 2nd ICS-MCL of 2.45 cm (95% CI 2.3 cm, 2.6 cm), 4th ICS-AAL 2.19cm (95% CI 2.02 cm, 2.36 cm). Conclusion: Median chest wall thickness varies little by height or location in children <13 years of age. The standard 5-cm needle is twice the chest wall thickness of most children. Commercially available 14 g or 16 g standard-length 3.8 cm (1½ inch) needles are of adequate length to access the pleural cavity, regardless of height as measured by Broselow LBT.

Left ventricular perforation with catheter decompression.

Thoracostomy tube placement is one of the more common procedures performed in the Emergency Department, most commonly for treatment of pneumothorax or hemothorax but occasionally for drainage of empyema or pleural effusion. Thoracostomy may be a life-saving procedure with a wide range of complication rates reported, ranging from 19.4-37%, most commonly extrathoracic placement. Most recent meta-analyses showed a relatively stable complication rate of 19% over the past three decades with the vast majority being benign in nature. We present a case with the rare complication of thoracostomy in which of a small-caliber thoracostomy tube was placed in the left ventricle. Although thoracotomy was performed to remove the catheter, the patient remained virtually asymptomatic and had an uneventful course.

External Validation of a Tube Thoracostomy Complication Classification System.

BACKGROUND: Tube thoracostomy (TT) is a commonly performed procedure which is associated with significant complication rates. Currently, there is no validated taxonomy to classify and compare TT complications across different populations. This study aims to validate such TT complication taxonomy in a cohort of South African trauma patients. METHODS: Post hoc analysis of a prospectively collected trauma database from Pietermaritzburg Metropolitan Trauma Service (PMTS) in South Africa was performed for the period January 2010 to December 2013. Baseline demographics, mechanism of injury and complications were collected and categorized according to published classification protocols. All patients requiring bedside TT were included in the study. Patients who necessitated operatively placed or image-guided TT insertion were excluded. Summary and univariate analyses were performed. RESULTS: A total of 1010 patients underwent TT. The mean age was (±SD) of 26 ± 8 years. Unilateral TTs were inserted in n = 966 (96%) and bilateral in n = 44 (4%). Complications developed in 162 (16%) patients. Penetrating injury was associated with lower complication rate (11%) than blunt injury (26%), p = 0.0001. Higher complication rate was seen in TT placed by interns (17%) compared to TT placed by residents (7%), p = 0.0001. Complications were classified as: insertional (38%), positional (44%), removal (9%), infective/immunologic (9%), and instructional, educational or equipment related (0%). CONCLUSIONS: Despite being developed in the USA, this classification system is robust and was able to comprehensively assign and categorize all the complications of TT in this South African trauma cohort. A universal standardized definition and classification system permits equitable comparisons of complication rates. The use of this classification taxonomy may help develop strategies to improve TT placement techniques and reduce the complications associated with the procedure. LEVEL OF EVIDENCE: V.

Management of hemothorax after thoracic endovascular aortic repair for ruptured aneurysms.

Background Thoracic aortic aneurysm rupture is often a fatal condition. Emergent thoracic endovascular aortic repair (TEVAR) has emerged as a suitable treatment option. Unfortunately, respiratory complications from hemothorax continue to be an important cause of morbidity and mortality even after successful management of the aortic rupture. We hypothesize that early hemothorax decompression after TEVAR for ruptured aneurysms decreases the rate of postoperative respiratory complications. Methods Single-center, retrospective eight-year review of ruptured thoracic aneurysms treated with TEVAR. Results Seventeen patients presented with ruptured degenerative thoracic aortic aneurysms, all of which were successfully treated emergently with TEVAR. The mean age was 74 years among the 12 (70.6%) men and 5 (29.4%) women treated. Inpatient and 30-day mortality rates for the entire cohort were both 17.6% (three patients). The 90-day mortality rate was 47.1% (eight patients). Thirty-day morbidities of the entire cohort included stroke ( n = 1, 5.9%), spinal cord ischemia ( n = 3, 17.6%; only one was temporary), cardiac arrest ( n = 4, 23.5%; 3 were fatal), respiratory failure ( n = 5, 29.4%), and renal failure ( n = 5, 29.4%). A large hemothorax was identified in the majority of patients ( n = 14, 82.4%). While six (42.9% of 14) patients had immediate chest tube decompression on the day of index procedure, three (21.4% of 14) patients had decompression on postoperative day 1, 4, and 7, respectively. Although not statistically significant, there were trends toward higher rates of respiratory failure (50.0% vs. 16.7%, P = 0.198) and 90-day mortality (62.5% vs. 33.3%, P = 0.280) for patients with delayed or no hemothorax decompression when compared to patients with immediate hemothorax decompression. Conclusions The morbidity and mortality of ruptured degenerative thoracic aortic aneurysms remains high despite the introduction of TEVAR. In this single-center experience, there was a trend toward decreased respiratory complications and increased survival with early chest decompression of hemothorax after TEVAR.

Fluoroscopically guided wide-bore thoracostomy tube placement: Description of the technique and comparison to blind placement.

OBJECTIVE: To describe and compare fluoroscopic guidance for placement of wide-bore thoracostomy tubes (FGTT) to traditional, blind placement of thoracostomy tubes (BPTT). STUDY DESIGN: Prospective clinical trial. ANIMALS: Twenty client-owned dogs. METHODS: Dogs requiring medical management of pleural effusion received a BPTT, whereas dogs undergoing postoperative management of pneumothorax and/or pleural fluid after lateral thoracotomy received an FGTT. Time of placement, accuracy of positioning, radiation exposure, and complications were compared between groups. RESULTS: Initial placement of BPTT took a mean of 168 seconds (range, 89-197), whereas adequate placement was radiographically confirmed at 20 minutes and 38 seconds (range, 7 minutes and 57 seconds to 39 min). Initial placement of FGTT took a mean time of 108 seconds (range, 50-341, P = .17), and adequate placement was confirmed at 125 seconds (range, 50-341, P < .001). Major errors in placement requiring removal and replacement occurred in 2 dogs for BPTT and in none for FGTT. Procedural complications did not differ between groups, and no postoperative complication occurred within the first 12 hours after placement. Radiation entrance surface dose was lower in the BPTT group (P = .004), but stochastic radiation doses did not differ. CONCLUSION: Fluoroscopic guidance of wide-bore thoracostomy tubes accelerated the time to accurate tube placement and alleviated the requirement for removal and replacement in this population. Although use of fluoroscopy increased radiation entrance surface dose, the dose was not clinically significant. CLINICAL SIGNIFICANCE: Fluoroscopic guidance of wide-bore thoracostomy tubes should be considered as an alternative to traditional, blind placement.

Thoracostomy tube function not trajectory dictates reintervention.

BACKGROUND: Hemothorax and/or pneumothorax can be managed successfully managed with tube thoracostomy (TT) in the majority of cases. Improperly placed tubes are common with rates near 30%. This study aimed to determine whether TT trajectory affects the rate of secondary intervention. METHODS: A retrospective review of all adult trauma patients undergoing TT placement over a 4-y period was performed. TT trajectory was classified as ideal, nonideal, or kinked-based on anterior-posterior chest x-ray. TTs with sentinel port outside the thoracic cavity were excluded. The primary outcome was any secondary intervention. RESULTS: Four-hundred eighty-six patients and a total of 547 hemithoraces underwent placement and met inclusion criteria. The majority of patients were male (76%), with a median age of 41 y, and majority suffered blunt trauma ideal trajectory was identified in 429 (78.4%). Kinked TTs were noted in 33 (6%) hemothoraces with a 45.5% replacement rate. Review with staff demonstrates inherent bias to replace kinked TTs. The overall secondary intervention rate was 27.8%. Kinked TTs were removed from final analysis due to treatment bias. Subsequent analysis demonstrated no significant difference between ideal and nonideal trajectories (25.1% versus 34.1%, P = 0.09). CONCLUSIONS: Intrathoracic trajectory of nonkinked TTs with the sentinel port within the thoracic cavity does not affect secondary intervention rates, including the rate of surgical intervention.

Thoracic irrigation prevents retained hemothorax: a pilot study.

BACKGROUND: Upward of 20% of patients undergoing thoracostomy tube (TT) placement develop retained hemothorax (HTx) requiring secondary intervention. The aim of this study was to define the rate of secondary intervention in patients undergoing prophylactic thoracic irrigation. METHODS: A prospective observational trial of 20 patients who underwent thoracic irrigation at the time of TT placement was conducted. Patients with HTx identified on chest x-ray were included. After standard placement of a 36-French TT, the HTx was evacuated using a sterile suction catheter advanced within the TT. Warmed sterile saline was instilled into the chest through the TT followed by suction catheter evacuation. The TT was connected to the sterile drainage atrium and suction applied. TTs were managed in accordance with our standard division protocol. RESULTS: The population was predominantly (70%) male at median age 35 years, median ISS 13, with 55% suffering penetrating trauma. Thirteen (65%) patients underwent TT placement within 6 h of trauma with the remainder within 24 h. Nineteen patients received the full 1000-mL irrigation. The majority demonstrated significant improvement on postprocedure chest x-ray. The secondary intervention rate was 5%. A single patient required VATS on post-trauma day zero for retained HTx. Median TT duration was 5 d with median length of stay of 7 d. No adverse events related to the pleural lavage were noted. CONCLUSIONS: Thoracic irrigation at the time of TT placement for traumatic HTx may decrease the rate of retained HTx.

Percutaneous Thermal Ablation for Small-Cell Lung Cancer: Initial Experience with Ten Tumors in Nine Patients.

PURPOSE: To evaluate outcomes in a small cohort of patients with local or disseminated small-cell lung cancer (SCLC) who received percutaneous thermal ablation therapy. MATERIALS AND METHODS: Ten biopsy-proven SCLC tumors in 9 consecutive patients (5 men, 4 women; average age, 73.8 y ± 12.4) were retrospectively evaluated. Average tumor sizes were 1.8 cm ± 0.5 and 2.6 cm ± 1.2 among patients with local and disseminated disease, respectively. Microwave and radiofrequency ablation were each used for 5 tumors. None of the patients with local SCLC received adjuvant therapy following thermal ablation. Median follow-up duration was 16 months (range, 2-48 mo). Median and 1-year overall survival (OS) were compared for patients in the local and disseminated disease groups. RESULTS: Median and 1-year OS were better among patients treated for local SCLC compared with disseminated disease (47.0 vs 5.5 mo and 3 [100%] vs 2 [40%], respectively). Pneumothorax occurred in 5 patients (55.6%), and 3 patients received successful outpatient thoracostomy tube placement. No patients were hospitalized, and there were no major complications. CONCLUSIONS: This preliminary analysis suggests favorable outcomes in selected patients with local SCLC who undergo percutaneous thermal ablation without adjuvant therapy.
