An Analysis of Tube Thoracostomy in Combat Implications for Improved Prehospital Recognition and Treatment.

BACKGROUND: Thoracic trauma occurs frequently in combat and is associated with high mortality. Tube thoracostomy (chest tube) is the treatment for pneumothorax resulting from thoracic trauma, but little data exist to characterize combat casualties undergoing this intervention. We sought to describe the incidence of these injuries and procedures to inform training and materiel development priorities. METHODS: This is a secondary analysis of a Department of Defense Trauma Registry (DoDTR) data set from 2007 to 2020 describing prehospital care within all theaters in the registry. We described all casualties who received a tube thoracostomy within 24 hours of admission to a military treatment facility. Variables described included casualty demographics; abbreviated injury scale (AIS) score by body region, presented as binary serious (=3) or not serious (<3); and prehospital interventions. RESULTS: The database identified 25,897 casualties, 2,178 (8.4%) of whom received a tube thoracostomy within 24 hours of admission. Of those casualties, the body regions with the highest proportions of common serious injury (AIS >3) were thorax 62% (1,351), extremities 29% (629), abdomen 22% (473), and head/neck 22% (473). Of those casualties, 13% (276) had prehospital needle thoracostomies performed, and 19% (416) had limb tourniquets placed. Most of the patients were male (97%), partner forces members or humanitarian casualties (70%), and survived to discharge (87%). CONCLUSIONS: Combat casualties with chest trauma often have multiple injuries complicating prehospital and hospital care. Explosions and gunshot wounds are common mechanisms of injury associated with the need for tube thoracostomy, and these interventions are often performed by enlisted medical personnel. Future efforts should be made to provide a correlation between chest interventions and pneumothorax management in prehospital thoracic trauma.

Efficacy of autologous blood patch injection for pneumothorax rate after CT-guided percutaneous transthoracic lung biopsy: a systematic review and meta-analysis.

BACKGROUND: Pneumothorax is the most frequent complication after CT-guided percutaneous transthoracic lung biopsy (CT-PTLB). Many studies reported that injection of autologous blood patch (ABP) during biopsy needle withdrawal could reduce the pneumothorax and chest tube insertion rate after CT-PTLB, but the result is debatable. The aim of this systematic review and meta-analysis is to synthesize evidence regarding the efficacy of ABP procedure in patients receiving CT-PTLB. METHODS: Eligible studies were searched in Pubmed, Embase and Web of Science databases. The inclusion criteria were studies that assessed the relationship between ABP and the pneumothorax and/or chest tube insertion rate after CT-PTLB. Subgroup analyses according to study type, emphysema status and ABP technique applied were also conducted. Odds ratio (OR) with 95% confidence interval (CI) were calculated to examine the risk association. RESULTS: A total of 10 studies including 3874 patients were qualified for analysis. Our analysis suggested that ABP reduced the pneumothorax (incidence: 20.0% vs. 27.9%, OR = 0.67, 95% CI = 0.48-0.66, P < 0.001) and chest tube insertion rate (incidence: 4.0% vs. 8.0%, OR = 0.47, 95% CI = 0.34-0.65, P < 0.001) after CT-PTLB. Subgroup analysis according to study type (RCT or retrospective study), emphysema status (with or without emphysema), and ABP technique applied (clotted or non-clotted ABP) were also performed and we found ABP reduced the pneumothorax and chest tube insertion rate in all subgroups. CONCLUSIONS: Our study indicated that the use of ABP was effective technique in reducing the pneumothorax and chest tube insertion rate after CT-PTLB.

Combination of transbronchoscopic oxygen insufflation and a digital chest drainage system in endobronchial occlusion: a hybrid technique for localization of fistula in intractable pneumothorax.

BACKGROUND: The management of intractable secondary pneumothorax poses a considerable challenge as it is often not indicated for surgery owing to the presence of underlying disease and poor general condition. While endobronchial occlusion has been employed as a non-surgical treatment for intractable secondary pneumothorax, its effectiveness is limited by the difficulty of locating the bronchus leading to the fistula using conventional techniques. This report details a case treated with endobronchial occlusion where the combined use of transbronchoscopic oxygen insufflation and a digital chest drainage system enabled location of the bronchus responsible for a prolonged air leak, leading to the successful treatment of intractable secondary pneumothorax. CASE PRESENTATION: An 83-year-old male, previously diagnosed with chronic hypersensitivity pneumonitis and treated with long-term oxygen therapy and oral corticosteroid, was admitted due to a pneumothorax emergency. Owing to a prolonged air leak after thoracic drainage, the patient was deemed at risk of developing an intractable secondary pneumothorax. Due to his poor respiratory condition, endobronchial occlusion with silicone spigots was performed instead of surgery. The location of the bronchus leading to the fistula was unclear on CT imaging. When the bronchoscope was wedged into each subsegmental bronchus and low-flow oxygen was insufflated, a digital chest drainage system detected a significant increase of the air leak only in B5a and B5b, thus identifying the specific location of the bronchus leading to the fistula. With the occlusion of those bronchi using silicone spigots, the air leakage decreased from 200 mL/min to 20 mL/min, and the addition of an autologous blood patch enabled successful removal of the drainage tube. CONCLUSION: The combination of transbronchoscopic oxygen insufflation with a digital chest drainage system can enhance the therapeutic efficacy of endobronchial occlusion by addressing the problems encountered in conventional techniques, where the ability to identify the leaking bronchus is dependent on factors such as the amount of escaping air and the location of the fistula.

Resident physician training in bedside pleural procedures: A one-year experience at a teaching hospital.

BACKGROUND AND OBJECTIVE: This study aims to quantify bedside pleural procedures performed at a quaternary teaching hospital describing technical and epidemiological aspects. MATERIALS AND METHODS: The authors retrospectively reviewed consecutive patients who underwent invasive thoracic bedside procedures between March 2022 and February 2023. RESULTS: 463 chest tube insertions and 200 thoracenteses were performed during the study period. Most procedures were conducted by 1st-year Thoracic Surgery residents, with Ultrasound Guidance (USG). There was a notable preference for small-bore pigtail catheters, with a low rate of immediate complications. CONCLUSION: Bedside thoracic procedures are commonly performed in current medical practice and are significant in surgical resident training. The utilization of pigtail catheters and point-of-care ultrasonography by surgical residents in pleural procedures is increasingly prevalent and demonstrates high safety.

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.

Conservative management versus invasive management of significant traumatic pneumothoraces in the emergency department (the CoMiTED trial): a study protocol for a randomised non-inferiority trial.

INTRODUCTION: Traumatic pneumothoraces are present in one of five victims of severe trauma. Current guidelines advise chest drain insertion for most traumatic pneumothoraces, although very small pneumothoraces can be managed with observation at the treating clinician's discretion. There remains a large proportion of patients in whom there is clinical uncertainty as to whether an immediate chest drain is required, with no robust evidence to inform practice. Chest drains carry a high risk of complications such as bleeding and infection. The default to invasive treatment may be causing potentially avoidable pain, distress and complications. We are evaluating the clinical and cost-effectiveness of an initial conservative approach to the management of patients with traumatic pneumothoraces. METHODS AND ANALYSIS: The CoMiTED (Conservative Management in Traumatic Pneumothoraces in the Emergency Department) trial is a multicentre, pragmatic parallel group, individually randomised controlled non-inferiority trial to establish whether initial conservative management of significant traumatic pneumothoraces is non-inferior to invasive management in terms of subsequent emergency pleural interventions, complications, pain, breathlessness and quality of life. We aim to recruit 750 patients from at least 40 UK National Health Service hospitals. Patients allocated to the control (invasive management) group will have a chest drain inserted in the emergency department. For those in the intervention (initial conservative management) group, the treating clinician will be advised to manage the participant without chest drain insertion and undertake observation. The primary outcome is a binary measure of the need for one or more subsequent emergency pleural interventions within 30 days of randomisation. Secondary outcomes include complications, cost-effectiveness, patient-reported quality of life and patient and clinician views of the two treatment options; participants are followed up for 6 months. ETHICS AND DISSEMINATION: This trial received approval from the Wales Research Ethics Committee 4 (reference: 22/WA/0118) and the Health Research Authority. Results will be submitted for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: ISRCTN35574247.

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.

Cryoablation Catheter Used in the Surgical Treatment of Atrial Fibrillation May Treat Chest Tube Pain: Engin Technique.

Postoperative pain after cardiac surgery plays an important role in the patient's recovery process. In particular, pain at the chest tube site can negatively affect the comfort and recovery of these patients. Effective pain control minimizes the risk of many complications. Oral and intravenous analgesics, epidural anesthesia, paravertebral block, and intercostal nerve blockade are used in chest tube pain control. We routinely use the surgical cryoablation method in the presence of atrial fibrillation in the preoperative period of cardiac surgery in our clinic. Here we aimed to describe our method of using the cryoablation catheter for intercostal nerve blockade.

Joint ERS/EACTS/ESTS clinical practice guidelines on adults with spontaneous pneumothorax.

BACKGROUND: The optimal management for spontaneous pneumothorax (SP) remains contentious, with various proposed approaches. This joint clinical practice guideline from the ERS, EACTS and ESTS societies provides evidence-based recommendations for the management of SP. METHODS: This multidisciplinary Task Force addressed 12 key clinical questions on the management of pneumothorax, using ERS methodology for guideline development. Systematic searches were performed in MEDLINE and Embase. Evidence was synthesised by conducting meta-analyses, if possible, or narratively. Certainty of evidence was rated with GRADE (Grading of Recommendations, Assessment, Development and Evaluations). The Evidence to Decision framework was used to decide on the direction and strength of the recommendations. RESULTS: The panel makes a conditional recommendation for conservative care of minimally symptomatic patients with primary spontaneous pneumothorax (PSP) who are clinically stable. We make a strong recommendation for needle aspiration over chest tube drain for initial PSP treatment. We make a conditional recommendation for ambulatory management for initial PSP treatment. We make a conditional recommendation for early surgical intervention for the initial treatment of PSP in patients who prioritise recurrence prevention. The panel makes a conditional recommendation for autologous blood patch in secondary SP patients with persistent air leak (PAL). The panel could not make recommendations for other interventions, including bronchial valves, suction, pleurodesis in addition to surgical resection or type of surgical pleurodesis. CONCLUSIONS: With this international guideline, the ERS, EACTS and ESTS societies provide clinical practice recommendations for SP management. We highlight evidence gaps for the management of PAL and recurrence prevention, with research recommendations made.

Bronchial Valves for Persistent Air Leak: A Systematic Review and Meta-analysis.

BACKGROUND: Patients with persistent air leak (PAL) pose a therapeutic challenge to physicians, with prolonged hospital stays and high morbidity. There is little evidence on the efficacy and safety of bronchial valves (BV) for PAL. METHODS: We systematically searched the PubMed and Embase databases to identify studies evaluating the efficacy and safety of BV for PAL. We calculated the success rate (complete resolution of air leak or removal of intercostal chest drain after bronchial valve placement and requiring no further procedures) of BV for PAL in individual studies. We pooled the data using a random-effects model and examined the factors influencing the success rate using multivariable meta-regression. RESULTS: We analyzed 28 observational studies (2472 participants). The pooled success rate of bronchial valves in PAL was 82% (95% confidence intervals, 75 to 88; 95% prediction intervals, 64 to 92). We found a higher success rate in studies using intrabronchial valves versus endobronchial valves (84% vs. 72%) and in studies with more than 50 subjects (93% vs. 77%). However, none of the factors influenced the success rate of multivariable meta-regression. The overall complication rate was 9.1% (48/527). Granulation tissue was the most common complication reported followed by valve migration or expectoration and hypoxemia. CONCLUSION: Bronchial valves are an effective and safe option for treating PAL. However, the analysis is limited by the availability of only observational data.

Feasibility of utilizing mediastinal drains alone following esophageal cancer surgery: a retrospective study.

BACKGROUND: It was typically necessary to place a closed thoracic drainage tube for drainage following esophageal cancer surgery. Recently, the extra use of thoracic mediastinal drainage after esophageal cancer surgery had also become more common. However, it had not yet been determined whether mediastinal drains could be used alone following esophageal cancer surgery. METHODS: A total of 134 patients who underwent esophageal cancer surgery in our department between June 2020 and June 2023 were retrospectively analyzed. Among them, 34 patients received closed thoracic drainage (CTD), 58 patients received closed thoracic drainage combined with mediastinal drainage (CTD-MD), while 42 patients received postoperative mediastinal drainage (MD). The general condition, incidence of postoperative pulmonary complications, postoperative NRS score, and postoperative anastomotic leakage were compared. The Mann-Whitney U tests, Welch's t tests, one-way ANOVA, chi-square tests and Fisher's exact tests were applied. RESULTS: There was no significant difference in the incidence of postoperative hyperthermia, peak leukocytes, total drainage, hospitalization days and postoperative pulmonary complications between MD group and the other two groups. Interestingly, patients in the MD group experienced significantly lower postoperative pain compared to the other two groups. Additionally, abnormal postoperative drainage fluid could be detected early in this group. Furthermore, there was no significant change in the incidence of postoperative anastomotic leakage and the mortality rate of patients after the occurrence of anastomotic leakage in the MD group compared with the other two groups. CONCLUSIONS: Using mediastinal drain alone following esophageal cancer surgery was equally safe. Furthermore, it could substantially decrease postoperative pain, potentially replacing the closed thoracic drain in clinical practice.

Late video-assisted thoracoscopic surgery versus thoracostomy tube reinsertion for retained hemothorax after penetrating trauma, a prospective randomized control study.

BACKGROUND: Early video-assisted thoracoscopic surgery (VATS) is the recommended treatment of choice for retained hemothorax (RH). A prospective single-center randomized control study was conducted to compare outcomes between VATS and thoracostomy tube (TT) reinsertion for patients with RH after penetrating trauma in a resource constrained unit. Our hypothesis was that patients with a RH receiving VATS instead of TT reinsertion would have a shorter hospital stay and lesser complications. MATERIALS AND METHODS: From January 2014 to November 2019, stable patients with thoracic penetrating trauma complicated with retained hemothoraces were randomized to either VATS or TT reinsertion. The outcomes were length of hospital stay (LOS) and complications. RESULTS: Out of the 77 patients assessed for eligibility, 65 patients were randomized and 62 analyzed: 30 in the VATS arm and 32 in the TT reinsertion arm. Demographics and mechanisms of injury were comparable between the two arms. Length of hospital stay was: preprocedure: VATS 6.8 (+/-2.8) days and TT 6.6 (+/- 2.4) days (p = 0.932) and postprocedure: VATS 5.1 (+/-2.3) days, TT 7.1 (+/-6.3) days (p = 0.459), total LOS VATS 12 (+/- 3.9) days, and TT 14.4 (+/-7) days (p = 0.224). The TT arm had 15 complications compared to the VATS arm of four (p = 0.004). There were two additional procedures in the VATS arm and 10 in the TT arm (p = 0.014). CONCLUSION: VATS proved to be the better treatment modality for RH with fewer complications and less need of additional procedures, while the LOS between the two groups was not statistically different.

Efficacy of nil per oral, total parenteral nutrition, milrinone and non-suction chest tube drainage-based management for chylothorax following pediatric cardiac surgery.

OBJECTIVE: A single centre experience with chylothorax in post cardiac surgical patients. METHODS: Retrospective review. RESULTS: Chylothorax developed in 55 out of 873 operated patients (6.3%). Median age of the chylothorax cohort was 95 days (range 1-995). Neonates constituted 36% and 49% were infants. Group-1(35 patients-treated during the years 2011-2015) included those who were managed with low fat diet initially with other standard measures including steroid, octreotide, pleurodesis, lymphangiogram or thoracic duct ligation whenever required.Group-2 (20 patients, treated between year 2016-2018) were managed with nil per oral, total parenteral nutrition, extended use of milrinone and no use of chest tube suction with other above standard measures when required.Group-1 and group-2 were comparable in terms of their age and weight (p > 0.05).We observed lower volume of chest drainage, shorter intubation time, length of intensive care stay and hospital stay in group-2 compared to group-1 though they were statistically not significant (p > 0.05). Occurrence of massive chylothorax (>20 ml/kg/day) in group-1 was significantly higher [18 patients (51%) in group-1 vs 4 patients in group-2 (20%) (Chi-square 5.25, p = 0.02)]. In hospital mortality in group-1 was higher compared to group-2 (5/35 = 14.5% vs 1/20 = 5%), however, it was statistically not significant [risk ratio 2.86; 95% CI 0.36, 22.77; p = 0.59)]. Acute kidney injury was observed in about 25% of patients who had chylothorax. A higher mortality was observed in patients with chylothorax who had acute kidney injury [5/14 (35%)] compared to those who did not have acute kidney injury [1/41 (2.4%)] (Chi-square 11.89, p = 0.001)]. SUMMARY: In a heterogenous cohort of post-cardiac surgical patients who developed chylothorax, our suggested new regime (nil per oral, parenteral nutrition, extended use of milrinone and no suction applied to the chest drains) contributed to reduce the frequency of massive chylothorax occurrence significantly.

The prevalence of pneumothorax in human immunodeficiency virus patients. A single center study.

OBJECTIVES: To assess the prevalence, risk factors, and associated complications of pneumothorax that are present in patients with human immunodeficiency virus (HIV) at our institution and to provide an updated local study addressing the association between pneumothorax and HIV. METHODS: This retrospective cohort study examined 161 patients who were admitted with a diagnosis of HIV from June 2017 to May 2022. They were divided into 2 groups depending on the presence of pneumothorax during their stay. Multiple variables were studied, including age, gender, tuberculosis infection, pneumocystis jiroveci pneumonia (PJP)infection, bacterial pneumonia, and pneumothorax type and treatment course. RESULTS: There were 11 patients diagnosed with pneumothorax (prevalence rate: 6.8%). Bacterial lung infection was found in 9 (81.8%) of these patients, while fungal infection was found in 6 (54.5%) (p<0.001, 0.010). The MTB was found in 3 (27.3%) patients (p=0.728), while none were infected with PJP. Intercostal tube insertion was attempted in 9 (81.8%) patients, the mean duration of tube stay was 39.3±30.7 days, and the mortality rate was 72.7% (p=0.007). CONCLUSION: Pneumothorax in patients with HIV is a manifestation of the progression of the disease and its poor outcome. It has a complicated treatment course and a high mortality rate.

Chest Tube Size Selection: Evaluating Provider Practices, Treatment Efficacy, and Complications in Management of Thoracic Trauma.

BACKGROUND: The standard for managing traumatic pneumothorax (PTX), hemothorax (HTX), and hemopneumothorax (HPTX) has historically been large-bore (LB) chest tubes (>20-Fr). Previous studies have shown equal efficacy of small-bore (SB) chest tubes (≤19-Fr) in draining PTX and HTX/HPTX. This study aimed to evaluate provider practice patterns, treatment efficacy, and complications related to the selection of chest tube sizes for patients with thoracic trauma. METHODS: A retrospective chart review was performed on adult patients who underwent tube thoracostomy for traumatic PTX, HTX, or HPTX at a Level 1 Trauma Center from January 2016 to December 2021. Comparison was made between SB and LB thoracostomy tubes. The primary outcome was indication for chest tube placement based on injury pattern. Secondary outcomes included retained hemothorax, insertion-related complications, and duration of chest tube placement. Univariate and multivariate analyses were performed. RESULTS: Three hundred and forty-one patients were included and 297 (87.1%) received LB tubes. No significant differences were found between the groups concerning tube failure and insertion-related complications. LB tubes were more frequently placed in patients with penetrating MOI, higher average ISS, and higher average thoracic AIS. Patients who received LB chest tubes experienced a higher incidence of retained HTX. DISCUSSION: In patients with thoracic trauma, both SB and LB chest tubes may be used for treatment. SB tubes are typically placed in nonemergent situations, and there is apparent provider bias for LB tubes. A future randomized clinical trial is needed to provide additional data on the usage of SB tubes in emergent situations.

[Prehospital chest tube placement: Which factors are associated with feeling confident to perform the procedure?] / Prähospitale Anlage von Thoraxdrainagen: Welche Faktoren sind mit einem subjektivem Sicherheitsgefühl assoziiert?

BACKGROUND: The prehospital placement of chest tubes is a rare but potentially life-saving procedure. A high level of subjective confidence with the procedure is essential for emergency medical doctors. This study aims to identify if there is a statistically significant difference in the subjective sense of confidence in prehospital chest tube placement regarding medical experience and qualification, clinical routine, and attendance at simulation courses. METHODS: Prehospital emergency physicians of three emergency medical services in Southwest Saxony, Greifswald, and Vechta, Germany, were invited to participate in an online survey from January to March 2022 using the online survey service limesurvey. The question "Do you feel confident in chest tube placement?" was used to measure the subjective level of confidence. Answers were compared with data concerning medical qualification, experience in prehospital emergency medicine, clinical routine, and attendance at simulation courses. Statistical analysis was performed using chi-squared test and Fisher's exact test. RESULTS: Three out of four participants felt confident in chest tube placement (53/71; 74.6%). More than half of the participants reported that they did not perform this procedure regularly (35/53, 66%). Subjective confidence was highest in physicians who regularly place chest tubes during their non-prehospital work (34/37; 91,9%; p<0.001), and more often when participants had clinical routine and attended simulation courses than when none of this applied (p=0.012). Attendance at simulation courses alone was not associated with a higher level of confidence (p=0.002). Specialists showed significantly more often subjective confidence in chest tube placement (p=0.0401). CONCLUSION: Prehospital chest tube placement is rare, but potentially lifesaving. An adequately high level of subjective confidence in the placement of chest tubes is a key condition for prehospital emergency doctors. Inhospital clinical routine and attendance at simulation courses are significantly associated with high levels of confidence. Our data indicate that working only in prehospital emergency settings without further clinical routine or medical specialization is not sufficient for achieving and ensuring subjective confidence in chest tube placement.

Enhanced recovery after surgery program focusing on chest tube management improves surgical recovery after video-assisted thoracoscopic surgery.

OBJECTIVE: Chest drainage is a standard procedure in thoracoscopic surgery for lung cancer. However, chest tube placement may deteriorate the ventilation capacity and increase difficulty of postoperative management of patients. The study investigated on the effects of enhanced recovery after surgery (ERAS) program focusing on chest tube management on surgical recovery of lung cancer patients. METHODS: The study population consisted of 60 patients undergoing video-assisted thoracoscopic surgery (VATS) after implementation of ERAS program and another group of 60 patients undergoing VATS before implementation of ERAS program. RESULTS: The mean time of first food intake was 12.9 h required for the ERAS group, which was significantly shorter than 18.4 h required for the control group (p < 0.0001). The mean time of out-of-bed activity was 14.2 h taken for the ERAS group, which was notably shorter than 22.8 h taken for the control group (p < 0.0001). The duration of chest tube placement was 68.6 h in the ERAS group, which was remarkably shorter than 92.8 h in the control group (p < 0.0001). The rate overall postoperative complications were notably lower in the ERAS group than in the control group (p = 0.018). The visual analogue score (VAS) scores on the second postoperative day exhibited significant differences between the ERAS group and the control group (p = 0.017). The patients in the ERAS group had a shorter hospitalization stay than those in the control group (p < 0.0001). CONCLUSION: The study suggests the ERAS program focusing on chest tube management could improve surgical recovery, remove patient chest tube earlier, and relieve patient pain after VATS.

Surgical approach and presence of preoperative pleural effusion impact thoracostomy tube usage in dogs and cats following thoracic surgery for suspected neoplasia.

OBJECTIVE: To assess factors associated with increased pleural fluid and air evacuation, longer duration of thoracostomy tube usage, and longer hospitalization in dogs and cats following surgery for thoracic neoplasms. ANIMALS: 62 dogs and 10 cats. METHODS: Medical records were reviewed for dogs and cats undergoing thoracic surgeries between August 1, 2019, and June 30, 2023, for resection of suspected neoplasia in which a thoracostomy tube was placed. Data collected included patient signalment, type of procedure performed, histologic diagnosis of the primary mass removed, volume of fluid and air evacuated from the thoracostomy tube, and time in hospital. RESULTS: Median sternotomy was associated with increased total fluid evacuation (median, 12.1 mL/kg; IQR, 15.4 mL/kg; P = .012), whereas rib resection was associated with increased total air evacuation (median, 2.1 mL/kg; IQR, 13.6 mL/kg; P = .06). The presence of preoperative pleural effusion was associated with higher total fluid evacuation (20.6 mL/kg; IQR, 32.1 mL/kg; P = .009), longer duration with a thoracostomy tube in place (42.5 hours; IQR, 41.9 hours; P = .027), and longer hospitalization period (61 hours; IQR, 52.8 hours; P = .025). Cats had a thoracostomy tube in place for a longer time compared to dogs (median, 42.6 hours; IQR, 23.5 hours; P = .043). CLINICAL RELEVANCE: Animals undergoing median sternotomy and rib resection may be expected to have higher fluid and air volumes, respectively, evacuated postoperatively. This often leads to an increased duration of thoracostomy tube usage and a longer period of hospitalization.
