Complications of Outpatient Chest Tube Management for Prolonged Air Leaks After Pulmonary Surgery.

PURPOSE: Air leaks are common after pulmonary surgery. Prolonged air leaks (PALs) may persist through discharge and often are managed with one-way valve devices (OWD). We sought to determine the course and complications of patients discharged with OWDs, risk factors for complications, and to evaluate the utility of clamp trials before chest tube (CT) removal. METHODS: Single-institution, retrospective review of patients discharged with a OWD after pulmonary surgery between 2008 and 2022. Charts were examined for the presence of complications and CT duration. Differences in CT duration were compared by using the Wilcoxon rank-sum test. RESULT: Sixty-four of 1917 (3.3%) pulmonary surgeries resulted in OWD use. Twelve of 64 (19%) patients discharged with a OWD suffered a complication. Nine of 64 (14%) had a CT-related readmission, and seven of 64 (11%) required PAL intervention. Patients sustaining a complication demonstrated longer CT durations before complication compared with duration in patients without complications, with median days of 13 [IQR 6-21] vs. 7 [IQR 6-12], p = 0.04). Five (7.8%) OWD patients developed an empyema; only one (20%) occurred before a CT duration of 14 days. Sixteen of 64 (25%) patients underwent a clamp trial before CT removal. One of ten (10%) failed even with no air leak present, whereas one of six (17%) failed with a present/questionable air leak. CONCLUSIONS: One-way valve device use has a substantial complication rate, and chest tube duration is a risk factor. In-hospital interventions might benefit patients with larger leaks that likely require prolonged OWD use. Because clamp trials occasionally fail, we contend that a clamp trial is the safest course before CT removal.

Timing of Chest Tube Removal Following Adult Cardiac Surgery: A Cluster Randomized Controlled Trial.

OBJECTIVES: Early chest tube removal following cardiac surgery may be associated with an increased risk of pleural or pericardial effusions following cardiac surgery. This study compares the effects of two fast-track chest tube removal protocols regarding the risk of pleural or pericardial effusions, requirement of opioids, respiratory function, and postoperative complications. DESIGN: Prospective non-blinded cluster-randomized study with alternating chest tube removal protocol in adult patients undergoing elective cardiac surgery. Monthly changing allocation to scheduled chest tube removal on the day of surgery (Day 0) versus removal on the 1st postoperative day (Day 1) provided no air leakage and output < 200 mL within the last four hours. RESULTS: A total of 527 patients were included in the study from September 1st 2020 until October 29th 2021 and randomly allocated to chest tube removal at day 0 (n = 255), and day 1 (n = 272). More than every fourth patient required drainage for pleural effusion with no significant difference between the groups. Earlier removal of chest tubes did not reduce requirement of analgesics, improve early respiratory function, or reduce postoperative complications. The study was halted for futility after halfway interim analysis showed insufficient promise of any treatment benefit. CONCLUSION: Fast-track protocols with chest tube removal within the first 24 h after cardiac surgery may be associated a high rate of pleural effusions.

Does pre-injury anticoagulation make chest tubes any less safe? A nationwide retrospective analysis.

BACKGROUND: Oral anticoagulation is becoming more common with the aging population, which raises concern for the risk of invasive procedures that can cause bleeding, such as chest tube placement (thoracostomy). With the increase in CT imaging, more pneumothoraces and hemothoraces are being identified. The relative risk of thoracostomy in the presence of anticoagulation is not well-established. The objective of this study was to determine whether pre-injury anticoagulation affects the relative risk of tube thoracostomy following significant chest trauma. METHODS: This retrospective cohort study used data from the 2019 American College of Surgeons-Trauma Quality Program (ACS-TQP) database using R version 4.2.2. Data from the database was filtered based on inclusion and exclusion criteria. Outcomes were then assessed with the population of interest. Demographics, vitals, comorbidities, and injury parameters were also collected for each patient. This study included all adult patients (≥18 years) presenting with traumatic hemothorax, pneumothorax, or hemopneumothorax. Patients with missing data in demographics, vitals, comorbidities, injury parameters, or outcomes, as well as those with no signs of life upon arrival, were excluded from the study. Patients were stratified into groups based on whether they had pre-injury anticoagulation and whether they had a chest tube placed in the hospital. The primary outcome was mortality, and the secondary outcome was hospital length of stay (LOS). Logistic and standard regressions were used by a statistician to control for age, sex, and Injury Severity Score (ISS). RESULTS: Our study population included 72,385 patients (4250 with pre-injury anticoagulation and 68,135 without pre-injury anticoagulation). Pre-injury anticoagulation and thoracostomy were each independently associated with increased mortality and LOS. However, there was a non-significant interaction term between pre-injury anticoagulation and thoracostomy for both outcomes, indicating that their combined effects on mortality and LOS did not differ significantly from the sum of their individual effects. CONCLUSION: This study suggests that both pre-injury anticoagulation and thoracostomy are risk factors for mortality and increased LOS in adult patients presenting with hemothorax, pneumothorax, or hemopneumothorax, but they do not interact with each other. We recommend further study of this phenomenon to potentially improve clinical guidelines. LEVEL OF EVIDENCE: Therapeutic, Level III.

Risk factors for delayed hemothorax in patients with rib fracture in the emergency department.

OBJECTIVES: Although rib fractures are a risk factor, not all rib fracture patients will develop delayed hemothorax. This study aimed to evaluate risk factors which can identify rib fracture patients in the emergency department who may develop delayed hemothorax. METHODS: Adult patients seen in the emergency room between January 2016 and February 2021 with rib fractures caused by blunt chest trauma were included in this retrospective observational study. Patients who underwent chest tube insertion within 2 days and those without follow-up chest radiographs within 2-30 days were excluded. We used a stepwise backward-elimination multivariable logistic regression model for analysis. RESULTS: A total of 202 patients were included in this study. The number of total (P < 0.001), lateral (P = 0.019), and displaced (P < 0.001) rib fractures were significantly associated with delayed hemothorax. Lung contusions (P = 0.002), and initial minimal hemothorax (P < 0.001) and pneumothorax (P < 0.001) were more frequently associated with delayed hemothorax. Age (adjusted odds ratio (aOR) 1.03, 95% confidence interval (CI) 1.00-1.06, P = 0.022), mechanical ventilator use (aOR 9.67, 95% CI 1.01-92.75, P = 0.049), initial hemothorax (aOR 2.21, 95% CI 1.05-4.65, P = 0.037) and pneumothorax (aOR 2.99, 95% CI 1.36-6.54, P = 0.006), and displaced rib fractures (aOR 3.51, 95% CI 1.64-7.53, P = 0.001) were independently associated with delayed hemothorax. CONCLUSIONS: Age, mechanical ventilation, initial hemo- or pneumothorax, and displaced rib fractures were risk factors for delayed hemothorax. Patients with these risk factors, and especially those with ≥2 displaced rib fractures, require close chest radiography follow-up of 2-30 days after the initial trauma.

The analgesic effects of combined bilateral parasternal block and serratus anterior plane block for coronary artery bypass grafting surgery.

BACKGROUND: Severe pain occurs after cardiac surgery in the sternum and chest tubes sites. Although analgesia targeting the sternum is often prioritized, the analgesia of the drain site is sometimes overlooked. This study of patients undergoing coronary artery bypass grafting (CABG) aimed to provide optimized analgesia for both the sternum and the chest tubes area by combining parasternal block (PSB) and serratus anterior plane block (SAPB). METHODS: Ethics committee approval (E.Kurul-E2-24-6176, 07/02/2024) was received for the study. Then, the trial was registered on www. CLINICALTRIALS: gov ( https://clinicaltrials.gov/ ) under the identifier NCT05427955 on 17/03/2024. Twenty patients between the ages of 18-80, with ASA physical status classification II-III, undergoing coronary artery bypass grafting CABG with sternotomy, were included. While the patients were under general anesthesia, PSB was performed through the second and fourth intercostal spaces, and SAPB was performed over the sixth rib. The primary outcome was VAS (Visual Analog Scale) during the first 12 h after extubation. The secondary outcomes were intraoperative remifentanil consumption and block-related side effects. RESULTS: The average age of the patients was 64 years. Five patients were female, and 15 were male. For the sternum area, only one patient had resting VAS scores of 4, while the VAS scores for resting for the other patients were below 4. For chest tubes area, only two patients had resting VAS scores of 4 or above, while the resting VAS scores for the other patients were below 4. The patients' intraoperative remifentanil consumption averaged 2.05 mg. No side effects related to analgesic protocol were observed in any of the patients. CONCLUSIONS: In this preliminary study where PSB and SAPB were combined in patients undergoing CABG, effective analgesia was achieved for the sternum and chest tubes area.

Effectiveness of Cold Therapy for Pain and Anxiety Associated with Chest Tube Removal: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

OBJECTIVES: To assess the effectiveness of cold therapy for pain and anxiety associated with chest tube removal. DESIGN: A Systematic review and meta-analysis of randomized controlled trials. DATA SOURCES: Articles were searched from Cochrane Library, PubMed, Embase, CINAHL, ProQuest, Airiti Library, China National Knowledge Infrastructure, and the National Digital Library of Theses and Dissertations in Taiwan. REVIEW/ANALYSIS METHODS: Eight electronic databases were searched from inception to August 20, 2022. The Cochrane Risk of Bias 2.0 tool was used to assess the quality of the included studies. Using a random-effects model, we calculated Hedges' g and its associated confidence interval to evaluate the effects of cold therapy. Cochrane's Q test and an I2 test were used to detect heterogeneity, and moderator and meta-regression analyses were conducted to explore possible sources of heterogeneity. Publication bias was assessed using a funnel plot, Egger's test, and trim-and-fill analysis. RESULTS: We examined 24 trials involving 1,821 patients. Cold therapy significantly reduced pain during and after chest tube removal as well as anxiety after chest tube removal (Hedges' g: -1.28, -1.27, and -1.80, respectively). Additionally, the effect size of cold therapy for reducing anxiety after chest tube removal was significantly and positively associated with that of cold therapy for reducing pain after chest tube removal. CONCLUSIONS: Cold therapy can reduce pain and anxiety associated with chest tube removal.

Training, experience, and perceptions of chest tube insertion by higher speciality trainees: implications for training, patient safety, and service delivery.

BACKGROUND: Seldinger Chest Tube Insertion (CTI) is a high acuity low occurrence procedure and remains a core capability for UK physician higher speciality trainee's (HST). A multitude of factors have emerged which may affect the opportunity of generalists to perform CTI. In view of which, this paper sought to establish the current experiences, attitudes, training, and knowledge of medical HST performing Seldinger CTI in acute care hospitals in the Peninsula deanery. METHODS: A Scoping review was performed to establish the UK medical HST experience of adult seldinger CTI. Synonymous terms for CTI training were searched across Cochrane, ERIC, Pubmed and British education index databases. Following which, a regional survey was constructed and completed by HST and pleural consultants from five hospitals within the Peninsula deanery between April-July 2022. Data collected included participants demographics, attitudes, training, experience, and clinical knowledge. Outcomes were collated and comparisons made across groups using SPSS. A p-value of < 0.05 was defined as significant. RESULTS: The scoping review returned six papers. Salient findings included low self-reported procedural confidence levels, poor interventional selection for patient cases, inadequate site selection for CTI and 1 paper reported only 25% of respondents able to achieve 5-10 CTI annually. However, all papers were limited by including grades other than HST in their responses. The regional survey was completed by 87 HST (12 respiratory, 63 non-respiratory medical HST and 12 intensivists/anaesthetists HST). An additional seven questionnaires were completed by pleural consultants. Respiratory HSTs performed significantly more Seldinger CTI than general and ICM/anaesthetic registrars (p < 0.05). The percentage of HST able to achieve a self-imposed annual CTI number were 81.8, 12.9 and 41.7% respectively. Self-reported transthoracic ultrasound competence was 100, 8 and 58% respectively (p < 0.001). The approach to clinical management significantly differed with national guidance with pleural consultants showing an agreement of 89%, respiratory HST 75%, general HST 52% and ICM/anaesthetic HST 54% (p = 0.002). CONCLUSION: Compared to respiratory trainees, non-respiratory trainees perform lower numbers of Seldinger CTI, with lower confidence levels, limited knowledge, and a reduced perceived relevance of the skill set. This represents a significant training and service challenge, with notable patient safety implications.

Teaching Chest Tube Insertion by Blended Learning: A Multi-Dimensional Analysis.

BACKGROUND: Emerging technologies are being incorporated in surgical education. The use of such technology should be supported by evidence that the technology neither distracts nor overloads the learner and is easy to use. To teach chest tube insertion, we developed an e-learning module, as part of a blended learning program delivered prior to in-person hands-on simulation. This pilot study was aimed to assess learning effectiveness of this blended learning, and cognitive load and the usability of e-learning. METHODS: The interactive e-learning module with multimedia content was created following learning design principles. In advance of the standard simulation, 13 first-year surgical residents were randomized into two groups: 7 received the e-learning module and online reading materials (e-learning group); 6 received only the online reading materials (controls). Knowledge was evaluated by pre-and post-tests; technical performance was assessed using a Global Rating Scale by blinded assessors. Cognitive load and usability were evaluated using rating scales. RESULTS: The e-learning group showed significant improvement from baseline in knowledge (P = .047), while controls did not (P = .500). For technical skill, 100% of residents in the e-learning group reached a predetermined proficiency level vs 60% of controls (P = .06). The addition of e-learning was associated with lower extrinsic and greater germane cognitive load (P = .04, .03, respectively). Usability was evaluated highly by all participants in e-learning group. CONCLUSION: Interactive e-learning added to hands-on simulation led to improved learning and desired cognitive load and usability. This approach should be evaluated in teaching of other procedural skills.

Medical and surgical management of pneumothorax in diving and hyperbaric chambers.

The presence of a pneumothorax within a pressurized chamber represents unique diagnostic and management challenges. This is particularly the case in the medical and geographic remoteness of many chamber locations. Upon commencing chamber decompression, unvented intrapleural air expands. If its initial volume and/or degree of chamber pressure reduction is significant enough, a tension pneumothorax will result. Numerous reports chronicle failure to diagnose and manage in-chamber pneumothorax with resultant morbidity and one fatal outcome. Such cases have occurred in both medically remote and clinically based settings. This paper reviews pneumothorax and tension pneumothorax risk factors and clinical characteristics. It suggests primary medical management using the principle of oxygen-induced inherent unsaturation in concert with titrated chamber decompression designed to prevent intrapleural air expanding faster than it contracts. Should this conservative approach prove unsuccessful, and surgical venting becomes necessary or otherwise immediately indicated, interventional options are reviewed.

Pneumothorax during manned chamber operations: A summary of reported cases.

In-chamber pneumothorax has complicated medically remote professional diving operations, submarine escape training, management of decompression illness, and hospital-based provision of hyperbaric oxygen therapy. Attempts to avoid thoracotomy by combination of high oxygen partial pressure breathing (the concept of inherent unsaturation) and greatly slowed rates of chamber decompression proved successful on several occasions. When this delicate balance designed to prevent the intrapleural gas volume from expanding faster than it contracts proved futile, chest drains were inserted. The presence of pneumothorax was misdiagnosed or missed altogether with disturbing frequency, resulting in wide-ranging clinical consequences. One patient succumbed before the chamber had been fully decompressed. Another was able to ambulate unaided from the chamber before being diagnosed and managed conventionally. In between these two extremes, patients experienced varying degrees of clinical compromise, from respiratory distress to cardiopulmonary arrest, with successful resuscitation. Pneumothorax associated with manned chamber operations is commonly considered to develop while the patient is under pressure and manifests during ascent. However, published reports suggest that many were pre-existing prior to chamber entry. Risk factors included pulmonary barotrauma-induced cerebral arterial gas embolism, cardiopulmonary resuscitation, and medical or surgical procedures usually involving the lung. This latter category is of heightened importance to hyperbaric operations as an iatrogenically induced pneumothorax may take as long as 24 hours to be detected, perhaps long after a patient has been cleared for chamber exposure.

Advancements in the Management of Postoperative Air Leak following Thoracic Surgery: From Traditional Practices to Innovative Therapies.

Background: Postoperative air leak (PAL) is a frequent and potentially serious complication following thoracic surgery, characterized by the persistent escape of air from the lung into the pleural space. It is associated with extended hospitalizations, increased morbidity, and elevated healthcare costs. Understanding the mechanisms, risk factors, and effective management strategies for PAL is crucial in improving surgical outcomes. Aim: This review seeks to synthesize all known data concerning PAL, including its etiology, risk factors, diagnostic approaches, and the range of available treatments from conservative measures to surgical interventions, with a special focus on the use of autologous plasma. Materials and Methods: A comprehensive literature search of databases such as PubMed, Cochrane Library, and Google Scholar was conducted for studies and reviews published on PAL following thoracic surgery. The selection criteria aimed to include articles that provided insights into the incidence, mechanisms, risk assessment, diagnostic methods, and treatment options for PAL. Special attention was given to studies detailing the use of autologous plasma in managing this complication. Results: PAL is influenced by a variety of patient-related, surgical, and perioperative factors. Diagnosis primarily relies on clinical observation and imaging, with severity assessments guiding management decisions. Conservative treatments, including chest tube management and physiotherapy, serve as the initial approach, while persistent leaks may necessitate surgical intervention. Autologous plasma has emerged as a promising treatment, offering a novel mechanism for enhancing pleural healing and reducing air leak duration, although evidence is still evolving. Conclusions: Effective management of PAL requires a multifaceted approach tailored to the individual patient's needs and the specifics of their condition. Beyond the traditional treatment approaches, innovative treatment modalities offer the potential to improve outcomes for patients experiencing PAL after thoracic surgery. Further research is needed to optimize treatment protocols and integrate new therapies into clinical practice.

Use of rocuronium and sugammadex for video-assisted thoracoscopic surgery is associated with reduced duration of chest tube drainage: a propensity score-matched analysis.

BACKGROUND: We investigated the influence of different neuromuscular blocking agents and reversal agents during anaesthesia on early removal of chest tube drainage after video-assisted thoracoscopic surgery (VATS). METHODS: This retrospective single-centre study included patients who underwent VATS after tracheal intubation under general anaesthesia. Patients received either cisatracurium and neostigmine (n=547) or rocuronium and sugammadex (n=151). Quantitative neuromuscular monitoring was used and one chest tube (size 24 Fr) was inserted. To reduce potential bias, 140 patients from each group were matched by propensity score for sex, age, body mass index and indication for VATS. Primary outcome was duration of chest tube drainage after surgery. RESULTS: Use of rocuronium and sugammadex was associated with a shorter duration of chest tube drainage (2 [1-2] vs 2 [1-3] days; P=0.049) and a 63% reduction in delayed chest tube removal (odds ratio 0.37; 95% confidence interval [CI]: 0.20-0.67; P=0.005). This group also had a lower incidence of postoperative atelectasis (P=0.047) and consolidation (P=0.008). Each 1 h increase in the duration of anaesthesia was associated with a 1.57-fold increase in the delayed removal of the chest tube (95% CI: 1.25-1.96; P=0.005). CONCLUSIONS: During general anaesthesia for VATS, compared with cisatracurium and neostigmine, use of rocuronium and sugammadex was associated with a significant decrease in the incidence of postoperative delayed removal of the chest tube, atelectasis, and pulmonary consolidation.

Experience of a modified chest tube suture-fixation technique in uniportal thoracoscopic pulmonary resection.

OBJECTIVE: This study aimed to explore the feasibility and advantages of a modified chest tube suture-fixation technique in uniportal video-assisted thoracic surgery for pulmonary resection. METHODS: A retrospective analysis was conducted on 116 patients who underwent uniportal video-assisted thoracic surgery (U-VATS) for lung diseases in Zhengzhou People's Hospital between October 2019 and October 2021. Patients were stratified into two groups based on the applied suture-fixation methods, i.e., 72 patients in the active group and 44 patients in the control group. The two groups were subsequently compared in the terms of gender, age, operation method, indwelling time of chest tube, postoperative pain score, chest tube removal time, wound healing grade, length of hospital stay, incision healing grade, and patient satisfaction. RESULTS: There was no significant difference between the two groups in terms of gender, age, operation method, indwelling time of chest tube, postoperative pain score, and length of hospital stay (P = 0.167, 0.185, 0.085, 0.051, 0.927, and 0.362, respectively). However, the chest tube removal time, incision healing grade, and incision scar satisfaction in the active group were significantly better compared with those of the control group (P = < 0.001, 0.033, and < 0.001, respectively). CONCLUSION: In summary, the new suture-fixation approach can minimize the number of stitches, and time necessary for chest tube removal process, and avoid the pain experienced when removing the drainage tube. This method is more feasible, has better incision conditions, and provides a convenient tube removal, making it more suitable to patients.

Feasibility of an improved knotless method of chest drain wound closure:a prospective cohort clinical trial.

OBJECTIVE: Chest tube management plays a key role in minimising erioperative period. We have improved the knotless method to chest tube wounds. In this article, we demonstrate the clinical bility and safety of this method. METHOD: From 13 October 2018-3 January 2019, patients were ecutively included in our study at the First Affiliated Hospital of n Medical University, Dalian, China. They were separated into approximately equally sized groups-the knotless group and the entional group. Our improved knotless method was performed ose the chest tube wounds of patients in the knotless group, and onventional method using the pre-existing U-shaped string to the chest tube wounds of patients in the conventional group. Patient clinical information, tube-related complications, retreatment s and cosmetic scores were compared between the groups. RESULTS: The cohort comprised 102 patients; 47 in the knotless group and 55 in the conventional group. There were no statistically significant differences in patient clinical information or tube-related complications between the two groups (p>0.05; both comparisons). In the knotless group, retreatment times were shorter (p<0.001) and cosmetic scores were higher (p<0.001). CONCLUSION: This study showed that our new knotless method is safe and has wide clinical feasibility. The new method also improved patient cosmetic scores. Furthermore, it decreased the patients' economic burdens.

Cold application for pain and anxiety reduction following chest tube removal: A systematic review and meta-analysis.

AIM AND OBJECTIVES: To conduct a systematic review and meta-analysis to evaluate the effects of cold application on pain and anxiety reduction after chest tube removal (CTR). BACKGROUND: The act of removing the chest tube often causes pain among cardiothoracic surgery patients. Most guidelines regarding CTR do not mention pain management. The effects of cold application on reducing pain and anxiety after CTR are inconsistent. DESIGN: Systematic review and meta-analysis. METHODS: We searched six databases, including Embase, Ovid Medline, Cochrane Library, Scopus, the Index to Taiwan Periodical Literature System and Airiti Library, to identify relevant articles up to the end of February 2021. We limited the language to English and Chinese and the design to randomised controlled trials (RCTs). All studies were reviewed by two independent investigators. The Cochrane Collaboration's tool was used to assess the risk of bias, Review Manager 5.4 was used to conduct the meta-analysis. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology was used for assessing certainty of evidence (CoE). RESULTS: Ten RCTs with 683 participants were included in the meta-analysis. The use of cold application could effectively reduce pain and anxiety after CTR. The subgroup showed that a skin temperature drops to 13°C of cold application was significantly more effective for the immediate reduction in pain intensity after CTR compared with control group. The GRADE methodology demonstrated that CoE was very low level. CONCLUSION: Cold application is a safe and easy-to-administer nonpharmacological method with immediate and persistent effects on pain and anxiety relief after CTR. Skin temperature drops to 13°C or lasts 20 min of cold application were more effective for immediate reduction of pain intensity following CTR. RELEVANCE TO CLINICAL PRACTICE: In addition to pharmacological strategy, cold application could be used as evidence for reducing pain intensity and anxiety level after CTR.

Evaluation of the efficacy of a modified method of treating the incisions of the single-port video-assisted thoracoscopic surgery using V-Loc™ barbed sutures.

This paper describes a modified method of applying unidirectional barbed sutures to treat the incisions of the single-port video-assisted thoracoscopic surgery (VATS) and discusses its safety and feasibility. This was a retrospective analysis of 108 patients who underwent single-port VATS admitted to the Department of Thoracic Surgery, the China-Japan Union Hospital of Jilin University, from April 2019 to April 2020. The experimental group (65 patients) was given unidirectional barbed sutures (V-Loc™ sutures) to treat the incision, and the control group (43 patients) had a skin stapler to treat the incision. The complications related to the incisions of the two groups were compared. There was no statistically significant difference between the experimental and control groups regarding incisional infection, incisional splitting, fat liquefaction, and incisional resewing. The pleural fluid outflow from the drainage orifice after removal of the chest tube (0 cases in the experimental group and 7 cases in the control group, P = 0.001) was significantly lower in the experimental group than in the control group. The scores of the scars showed that the experimental group was significantly better than the control group. The modified method of treating the incisions of the single-port VATS with V-Loc™ sutures has good efficacy and safety. It reduces the incidence of pleural fluid outflow from the drainage orifice after removal of the chest tube compared with the traditional stapler suture method, and it has superior cosmetic outcomes.

A small-sized tube versus traditional closed thoracic drainage in uniportal thoracoscopic surgery.

Introduction: To assess the feasibility and safety of placing a small-sized tube as drainage in patients after uniportal thoracoscopic lung resection. Patients and Methods: Patients who received uniportal video-assisted thoracoscopic surgery (U-VATS) lung resection were identified in our database. Patients placed small-sized tube drainage were compared with those placed conventional chest tube in terms of characteristics, operation modality, post-operative pulmonary complications, post-operative pain, chest tube duration and post-operative hospital stay. Propensity score matching was performed. Results: Of the 217 enrolled patients, 173 were assigned to the conventional tube group and 44 were assigned to the small-sized tube group. Rates of post-operative pulmonary complications were relatively low and similar between the two groups. After propensity score matching, operation duration was shorter (1 h vs. 1.21 h, P = 0.01) was shorter, and the maximum value of the Visual Analogue Scale (VAS) score after operation (1 vs. 1.5, P = 0.02) and the overall average value of VAS score after operation (0.33 vs. 0.88, P = 0.006) was lower in small-sized tube group. No significant difference was observed in chest tube duration (2 vs. 2, P = 0.34) and post-operative hospital stay (3 vs. 3, P = 0.34). Conclusions: Compared to conventional chest tubes, small-sized tubes for post-operative drainage after U-VATS lung resection may be a safe and promising approach for reducing post-operative pain.

Are Routine Chest Radiographs After Chest Tube Removal in Thoracic Surgery Patients Necessary?

INTRODUCTION: The routine use of chest x-ray (CXR) to evaluate the pleural space after chest tube removal is a common practice driven primarily by surgeon preference and institutional protocol. The results of these postpull CXRs frequently lead to additional interventions that serve only to increase health care costs and resource utilization. We investigated the utility of these postpull CXRs in thoracic surgery patients and assessed their effectiveness in predicting the need for tube replacement. METHODS: Single-institution retrospective study comprising thoracic surgery patients requiring postoperative chest tube drainage over a 3-y period. Demographics and surgical characteristics, including surgical approach, procedure, and procedure type, were recorded. Outcomes included postpull CXR findings, interventions resulting from radiographic abnormalities, and the additional health resource utilization incurred by obtaining these studies on asymptomatic patients. RESULTS: The study included 433 patients. Postpull CXRs were performed in 87.1% of patients, with 33.2% demonstrating an abnormality compared with the prior study. Among these, 65.7% resulted only in repeat imaging and 25.7% resulted in discharge delay. Overall, a total of 13 patients (3%) required chest tube replacement, three during the index hospitalization and the other 10 requiring readmission. Among those requiring chest tube replacement, 75% had normal postpull imaging, and all were symptomatic. CONCLUSIONS: Recurrent pneumothorax after chest tube removal requiring immediate tube reinsertion is relatively rare and does not occur in the absence of symptoms. Our study suggests that routine postpull CXRs have limited clinical utility and can be safely omitted in asymptomatic patients with appropriate clinical observation.

The Volume of Thoracic Irrigation Is Associated With Length of Stay in Patients With Traumatic Hemothorax.

INTRODUCTION: Irrigation of the thoracic cavity at tube thoracostomy (TT) placement may decrease the rate of a retained hemothorax (RHTX); however, other resource utilization outcomes have not yet been quantified. This study evaluated the association of thoracic irrigation during TT with the length of stay and outcomes in patients with traumatic hemothorax (HTX). METHODS: A retrospective chart review was performed of adult patients receiving a TT for HTX at a single, urban Level 1 Trauma Center from January 2019 to December 2020. Those who underwent irrigation during TT at the discretion of the trauma surgeon were compared to a control of standard TT without irrigation. Death within 30 d, as well as TTs, placed at outside hospitals, during traumatic arrest or thoracic procedures, and for isolated pneumothoraces were excluded. The primary outcome was the length of stay as hospital-free, ICU-free, and ventilator-free days (30-day benchmark). Subgroup analysis by irrigation volume was conducted using one-way ANOVA testing with P < 0.05 considered statistically significant. RESULTS: Eighty-two (41.4%) of 198 patients underwent irrigation during TT placement. Secondary interventions, thoracic infections, and TT duration were not statistically different in the irrigated cohort. Hospital-free and ICU-free days were higher in the irrigated patients than in the controls. Groups irrigated with ≥1000 mL had significant more hospital-free days (P = 0.007) than those receiving less than 1000 mL. CONCLUSIONS: Patients with traumatic HTX who underwent thoracic irrigation at the time of TT placement had decreased hospital and ICU days compared to standard TT placement alone. Specifically, our study demonstrated that patients irrigated with a volume of at least 1000 mL had greater hospital-free days compared to those irrigated with less than 1000 mL.

Thoracostomy Tube Removal in Pediatric Trauma: Film or No Film?

BACKGROUND: Use of routine chest x-rays (CXR) following thoracostomy tube (TT) removal is highly variable and its utility is debated. We hypothesize that routine post-pull chest x-ray (PP-CXR) findings following TT removal in pediatric trauma would not guide the decision for TT reinsertion. METHODS: Patients ≤ 18 y who were not mechanically ventilated and undergoing final TT removal for a traumatic hemothorax (HTX) and/or pneumothorax (PTX) at a level I pediatric trauma center from 2010 to 2020 were retrospectively reviewed. The outcomes of interest were rate of PP-CXR and TT reinsertion rate following PP-CXR. Clinical predictors for worsened findings on PP-CXR were also assessed. RESULTS: Fifty-nine patients were included. A CXR after TT removal was performed in 57 patients (97%), with 28% demonstrating worsened CXR findings compared to the prior film. Except for higher ISS (p = 0.033), there were no demographic or clinical predictors for worsened CXR findings. However, they were more likely to have additional films following the TT removal (p = 0.008) than those with stable or improved PP-CXR findings. One (1.8%) asymptomatic child with worsened PP-CXR findings had TT reinsertion based purely on their worsened PP-CXR findings. CONCLUSIONS: The vast majority of PP-CXR did not guide TT reinsertion after pediatric thoracic trauma. Treatment algorithms may aid to reduce variability and potentially unnecessary routine films.
