Digital chest drainage system versus traditional chest drainage system after pulmonary resection: a systematic review and meta-analysis

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 a Digital Air Leak Detection Device to Decrease Chest Tube Duration

BACKGROUND

The aim of this evidence-based practice project was to determine if a digital air leak detection device could speed the identification of chest tube air leak cessation in patients after pulmonary lobectomy. Staff members assessing air leaks have varying levels of expertise, and the digital device is a limited resource in the study institution. A chest tube management algorithm is necessary to standardize care and determine which patients are most likely to benefit.

IMPLEMENTATION

Twenty-five consecutive patients who underwent pulmonary lobectomy during the study period and continued to have a chest tube air leak on postoperative day 3 were monitored with digital air leak detection devices. The Mann-Whitney U test was used to compare chest tube duration and hospital length of stay between patients with digital devices and 259 patients who had traditional analog air leak detection devices (historical data from the departmental database over the previous 2 years).

EVALUATION

Median chest tube duration and hospital stay were 1 day less in patients with digital devices than in those with traditional analog devices (P = .01 and P = .004, respectively), with a cost savings of $2659 per hospital day. Reductions in chest tube duration and length of stay aided in the development of a chest tube management algorithm.

CONCLUSIONS

Critical care nurses are valued team members who treat patients after lung resections. Digital air leak detection devices can help them assess air leaks more accurately, benefiting the patients in their care.

Conventional and digital pleural drainage systems - advantages and disadvantages

INTRODUCTION

Pleural cavity drainage is a crucial component of the surgical management of patients with various chest diseases. Digital drainage systems are increasingly used in contemporary thoracic surgical procedure, which is likely a result of their effectiveness in achieving early postoperative ambulation, cutting down on hospital stays and lowering costs. The vast majority of thoracic surgeons worldwide prefer digital drainage systems to traditional ones. The advantages of the former, however, are disputed by some researchers.

Outcomes of chest drain management using only air leak (without fluid) criteria for removal after general thoracic surgery-a drainology study

Background

Chest drain management is a variable aspect of postoperative care in thoracic surgery, with different opinion for air and drain volume output. We aim to study if acceptable safety was maintained using air leak criteria alone.

Methods

A 9-year retrospective analysis of protocolised chest drain management using digital drain air leak cut off less than 20 mL/min for more than 6 h for drain removal in patients undergoing general thoracic surgery. We excluded patients if a chest drain was not required nor removed during admission or if patients underwent volume reduction or pneumonectomy. Withdrawal criteria were suspected bleeding or chylothorax. Postoperative films were reviewed to document post-drain removal pneumothorax, pleural effusion, and reintervention (drain re-insertion).

Results

Between 2012 and 2021, 1,187 patients had thoracic surgery under a single surgeon. Following exclusion and withdrawal criteria, 797 patients were left for analysis. The mean age [standard deviation (SD)] was 61 [16] years and 383 (48%) were male. Median [interquartile range (IQR)] duration of drain insertion was 1 [1-2] day with a median length of hospital stay of 4 [2-6] days. Post-drain removal pneumothorax was observed in 141 (17.7%), post-drain removal pleural effusion was observed in 75 (9.4%) and re-intervention (reinsertion of chest drain) required in 17 (2.1%).

Conclusions

Our results demonstrate acceptable levels of safety using digital assessment of air leak as the sole criteria for drain removal in selected patients after general thoracic surgery.

Comparison Between Electronic and Traditional Chest Drainage Systems: A Multicenter Randomized Study

BACKGROUND

Air leak is the major factor that influences the permanence of the chest tube and the in-hospital length of stay (LOS) among patients undergoing lung resections. The aim of this study was to determine whether the use of digital chest drain systems, compared with traditional ones, reduced the duration of chest drainage and postoperative in-hospital LOS in patients undergoing video-assisted thoracoscopic (VATS) lobectomy.

METHODS

The study was a prospective, randomized, multicenter trial. Patients undergoing VATS lobectomy were randomized in 2 groups, receiving a digital drain system or a traditional one and managed accordingly to the protocol.

RESULTS

Among 503 patients who fulfilled inclusion criteria and were randomized, 38 dropped out after randomization. Finally, 465 patients were analyzed, of whom 204 used the digital device and 261 the traditional one. In the digital group, there was a significantly shorter median chest tube duration of 3 postoperative days (interquartile range [IQR], 2-4 days) vs 4 postoperative days (IQR, 3-4 days; P = .001) and postoperative in-hospital LOS of 4 days (IQR, 3-6 days) vs 5 days (IQR, 4-6 days; P = .035). Analysis of predictors for increased duration of air leaks showed a relationship with male sex (P = .039), forced expiratory volume in 1 second percentage (P = .004), forced vital capacity percentage (P = .03), and presence of air leaks at the end of surgery (P = .001).

CONCLUSIONS

In patients undergoing VATS lobectomy, the use of a digital drainage system allows an earlier removal of the chest drain compared with the traditional system, leading to a shorter in-hospital LOS.

Patients' Perceptions of Experiences of Postoperative Chest Drain Tube Insertion: A Pilot Survey

BACKGROUND

Pleural drainage is a routine procedure conducted after thoracotomy and thoracoscopy. It is used to remove air or excess fluid from a pleural cavity and enables proper lung expansion. Essential elements of care provided during hospitalization and treatment include meeting patients' growing expectations and continually improving quality while optimizing safety.

AIM

This study aimed to explore patients' experiences with pleural drainage after thoracic surgery and their correlation with socio-demographic data.

METHODS

A pilot survey with an exploratory design was conducted at a large teaching hospital in Poland, in the Department of Thoracic Surgery at the University Clinical Centre in Gdansk. The study involved the analysis of 100 randomly selected subjects with a chest tube drain. A self-designed questionnaire was used to collect social, demographic, and clinical data. Twenty-three questions related to experiences with pleural drainage, ailments, limitations in daily functioning, and security with a chest tube were evaluated using a 5-point Likert scale. Patients completed the questionnaire on the third postoperative day.

RESULTS

Individuals fitted with a traditional water-seal drainage system felt safer than those from the digital drainage group (p = 0.017). Statistically significant differences were found in the assessment of nursing assistance (p = 0.025); the number of satisfied patients was greater in a group of unemployed people. No correlation was found between demographic and social factors and the patients' sense of security (gender: p = 0.348, age: p = 0.172, education level: p = 0.154, professional activity: p = 0.665).

CONCLUSIONS

Demographic and social characteristics did not significantly affect patients' sense of safety with chest drainage types. Patients with traditional drainage felt significantly safer than patients with digital drainage. Patient knowledge of pleural drainage management was not satisfactory, with a number of patients indicating a lack of knowledge in this area. This is important information that should be considered when planning measures to improve the quality of care.

Advantages of applying digital chest drainage system for postoperative management of patients following pulmonary resection: a systematic review and meta-analysis of 12 randomized controlled trials

OBJECTIVES

This meta-analysis aimed to evaluate the value of the chest digital drainage system for the postoperative management of patients who have undergone pulmonary resection.

METHODS

We searched the PubMed, EMBASE, the Cochrane Library, and Web of Science databases for included randomized controlled trials (RCTs) on the application of digital drainage systems versus the analog drainage system for patients with lung disease after pulmonary resection. Dichotomous variables were evaluated using risk ratios (RRs) and 95% confidence intervals (CIs), and mean and standardized mean differences (MDs and SMDs, respectively) with 95% CIs were used to calculate continuous variables. Statistical analyses were performed using Stata and RevMan software.

RESULTS

In total, 12 RCTs involving 2000 patients were analyzed. Significant differences in duration of chest tube placement (SMD =  -0.49; 95% CI =  -0.78 to -0.20), length of hospital stay (MD =-0.79 days; 95% CI = -1.24 to -0.34), and number of chest tube clamping tests (RR = 0.74; 95% CI = 0.36-1.49) were observed between the two groups, which did not significant differ in the occurrence of prolonged air leak or cardiopulmonary complication rate.

CONCLUSIONS

The digital chest drainage system is mainly advantageous in the duration of chest tube placement, length of hospital stay, and number of chest tube clamping tests. Future research should evaluate the requirements and economic impact of using digital system in routine clinical practice.

Comparison of clinical utility between digital and analog drainage systems in patients with spontaneous pneumothorax

BACKGROUND

Digital drainage systems can continuously and numerically monitor air leakage, which may lead to a shorter duration of drainage and hospitalization; however, the usefulness of digital drainage systems compared to that of analog drainage systems for patients with primary or secondary spontaneous pneumothorax remains unclear.

METHODS

This retrospective study included 108 patients with spontaneous pneumothorax who were successfully treated with chest drainage alone at our institution. We compared the clinical efficacy of digital and analog chest drainage systems.

RESULTS

From the study population, 68 patients were diagnosed with primary and the other 40 with secondary spontaneous pneumothorax. The analog drainage system was used in 44 patients, and the digital drainage system in 64 patients. Among patients with primary spontaneous pneumothorax, the digital group had a significantly shorter duration of chest drainage than the analog group (median 2 vs. 4 days; p = 0.001), but there was no significant difference in those with secondary spontaneous pneumothorax. Additionally, the length and cost of hospitalization in the digital group were significantly lower than those in the analog group for both patients with primary and secondary spontaneous pneumothorax. There was no significant difference in recurrence within 1 week after chest tube removal between the two groups, neither among patients with primary nor among those with secondary pneumothorax.

CONCLUSIONS

Digital drainage system may be better than analog drainage system for patients with primary spontaneous pneumothorax who need chest drainage, but further research is needed on drainage system selection for those with secondary disease.

Recommendations of the Society of Thoracic Surgery and the Section of Cardiothoracic and Vascular Surgery of the Spanish Society of Anesthesia, Resuscitation and Pain Therapy, for patients undergoing lung surgery included in an intensified recovery program

In recent years, multidisciplinary programs have been implemented that include different actions during the pre, intra and postoperative period, aimed at reducing perioperative stress and therefore improving the results of patients undergoing surgical interventions. Initially, these programs were developed for colorectal surgery and from there they have been extended to other surgeries. Thoracic surgery, considered highly complex, like other surgeries with a high postoperative morbidity and mortality rate, may be one of the specialties that most benefit from the implementation of these programs. This review presents the recommendations made by different specialties involved in the perioperative care of patients who require resection of a lung tumor. Meta-analyzes, systematic reviews, randomized and non-randomized controlled studies, and retrospective studies conducted in patients undergoing this type of intervention have been taken into account in preparing the recommendations presented in this guide. The GRADE scale has been used to classify the recommendations, assessing on the one hand the level of evidence published on each specific aspect and, on the other hand, the strength of the recommendation with which the authors propose its application. The recommendations considered most important for this type of surgery are those that refer to pre-habilitation, minimization of surgical aggression, excellence in the management of perioperative pain and postoperative care aimed at providing rapid postoperative rehabilitation.

Promising Effects of Digital Chest Tube Drainage System for Pulmonary Resection: A Systematic Review and Network Meta-Analysis

Objective: The chest tube drainage system (CTDS) of choice for the pleural cavity after pulmonary resection remains controversial. This systematic review and network meta-analysis (NMA) aimed to assess the length of hospital stay, chest tube placement duration, and prolonged air leak among different types of CTDS. Methods: This systemic review and NMA included 21 randomized controlled trials (3399 patients) in PubMed and Embase until 1 June 2021. We performed a frequentist random effect in our NMA, and a P-score was adopted to determine the best treatment. We assessed the clinical efficacy of different CTDSs (digital/suction/non-suction) using the length of hospital stay, chest tube placement duration, and presence of prolonged air leak. Results: Based on the NMA, digital CTDS was the most beneficial intervention for the length of hospital stay, being 1.4 days less than that of suction CTDS (mean difference (MD): −1.40; 95% confidence interval (CI): −2.20 to −0.60). Digital CTDS also had significantly reduced chest tube placement duration, being 0.68 days less than that of suction CTDSs (MD: −0.68; 95% CI: −1.32 to −0.04). Neither digital nor non-suction CTDS significantly reduced the risk of prolonged air leak. Conclusions: Digital CTDS is associated with better outcomes than suction and non-suction CTDS for patients undergoing pulmonary resections, specifically 0.68 days shorter chest tube duration and 1.4 days shorter hospital stay than suction CTDS.

Clinical efficacy of digital chest drainage system in cardiac valve surgery

OBJECTS

The portable digitalized suction was used widely in thoracic surgery. The aim of the study was to access the early outcomes of using the portable digitalized suction system after cardiac surgery.

METHODS

We invested 80 patients including 30 women (mean age 72.7 ± 9.2 years) who underwent cardiac surgery at our hospital, excluded coronary artery bypass grafting only, with or only aortic surgery, emergency operation, and patients with hemodialysis. Patients were categorized as those treated with digital chest drainage system (DCS group, n = 38) or analog chest drainage system (ACS group, n = 42), and the following data were analyzed in two groups. The primary endpoint was the duration of chest drainage, and the secondary endpoints were the rate of drainage-related complications and the length of hospitalization.

RESULTS

The duration of drainage was significantly shorter in the DCS group (ACS vs. DCS = 94.8 ± 31.5 vs. 81.1 ± 20.6 h, p = 0.036). The duration needed for rehabilitation completion was significantly shorter in the DCS group (ACS vs. DCS = 10.7 ± 1.2 vs. 9.6 ± 1.5 days, p = 0.047), and the length of hospitalization was significantly shorter in the DCS group (ACS vs. DCS = 21.9 ± 5.3 vs. 18.8 ± 7.2 days, p = 0.031).

CONCLUSIONS

This study provided evidence that DCS might be effective for patients who underwent cardiac valve surgery.

Multicenter randomized controlled trial comparing digital and traditional chest drain in a VATS pulmonary lobectomy cohort: interim analysis

Background

The usefulness of digital chest drain is still debated. We are carrying out a study to determine if the use of a digital system compared with a traditional system reduces the duration of chest drainage. To evaluate safety, benefit, or futility of this trial we planned the current interim analysis.

Methods

An interim analysis on preliminary data from ongoing investigator-initiated, multicenter, interventional, prospective randomized trial. Original protocol number: (NCT03536130). The interim main endpoint was overall complications; secondary endpoints were the concordance between the two primary endpoints of the RCT (chest tube duration and length of hospital stay). We planned the interim analysis when half of the patients have been randomised and completed the study. Data were described using mean and standard deviation or absolute frequencies and percentage. T-test for unpaired samples, Chi-square test, Poisson regression and absolute standardized mean difference (ASMD) were used. P-value < 0.05 was considered significant.

Results

From April 2017 to November 2018, out of 317 patients enrolled by 3 centers, 231 fulfilled inclusion criteria and were randomized. Twenty-two of them dropped out after randomization. Finally, 209 patients were analyzed: among them 94 used the digital device and 115 the traditional one. The overall postoperative complications were 35 (16.8%) including prolonged air leak (1.9%). Mean chest tube duration was 3.6 days (SD = 1.8), with no differences between two groups (p = 0.203). The overall difference between hospital stay and chest tube duration was 1.4 days (SD = 1.4). Air leak at first postoperative day detected by digital and traditional devices predicted increasing in tube duration of 1.6 day (CI 95% 0.8–2.5, p < 0.001) and 2.0 days (CI 95% 1.0–3.1, p < 0.001), respectively.

Conclusions

This interim analysis supported the authors’ will to continue with the enrollment and to analyze data once the estimated sample size will be reached.

Low suction on digital drainage devices promptly improves post-operative air leaks following lung resection operations: a retrospective study

BACKGROUND

We investigated the most effective suction pressure for preventing or promptly improving postoperative air leaks on digital drainage devices after lung resection.

METHODS

We retrospectively analyzed the postoperative data of 242 patients who were monitored with a digital drainage system after pulmonary resection in our institution between December 2017 and June 2020. We divided the patients into three groups according to the suction pressure used: A (low-pressure suction group: - 5 cm H₂O), B (intermediate-pressure group: - 10 cm H₂O), and C (high-pressure suction group: - 20 cm H₂O). We evaluated the duration of air leaks, timing of chest tube replacement, the amount of postoperative air leak, volume of fluid drained before chest tube removal, and the total number of air leaks during drainage.

RESULTS

In total, 217 patients were included in this study. The duration of air leaks gradually decreased with significant difference between the groups, the highest decrease in A, the lowest decrease in C (P = 0.019). Timing of chest tube replacement, on the other hand, did not significantly differ between the three groups (P = 0.126). The number of postoperative air leaks just after surgery did not significantly differ between the three groups (P = 0.175), but the number of air leaks on postoperative day 1 were fewest in group A, then B, and greatest in group C (P = 0.033). The maximum amount of air leaks during drainage was lowest in A, then B, and highest in C (P = 0.036). Volume of fluid drained before chest tube removal did not significantly differ between the three groups (P = 0.986).

CONCLUSION

Low-pressure suction after pulmonary resection seems to avoid or promptly improve postoperative air leaks in digital drainage devices after lung resection.

TRIAL REGISTRATION

This is a single-institution, retrospective analysis-based study of data from an electronic database. Study protocol was approved by the Akashi Medical Center Institutional Research Ethics Board (approval number: 2020-9).

Safety and efficacy of digital chest drainage units compared to conventional chest drainage units in cardiac surgery

OBJECTIVES

The use of digital chest drainage units (CDUs) has become increasingly common in thoracic surgery due to several advantages. However, in cardiac surgery, its use is still limited in favour of conventional analogue CDUs. In order to investigate the potential benefit of digital CDUs in cardiac surgery, we compared the safety and efficacy of both systems in patients undergoing cardiac surgery at our centre.

METHODS

We retrospectively investigated 265 consecutive patients who underwent cardiac surgery at our institution between June 2017 and October 2017. These patients were divided into 2 groups: patients with analogue (A, n = 65) and digital CDUs (D, n = 200). Postoperative outcome was analysed and compared between both groups. In addition, the 'user experience' was evaluated by means of a questionnaire.

RESULTS

The median age of the cohort was 70 years (P = 0.167), 25.3% of patients were female (P = 0.414). There were no differences in terms of re-explorative surgery or use of blood products. Nor was there a difference in the overall amount of fluid collected. However, during the first 6 h, more fluid was collected by the digital CDUs. The overall rate of technical failure was 0.4%. We observed a significantly higher rate of clotting in the tubing system of the digital CDUs (P = 0.042). Concerning the user experience, the digital CDUs were associated with a more favourable ease of use on the regular wards (P < 0.001). With regard to the overall user experience, the digital CDUs outperformed the analogue systems (P = 0.002).

CONCLUSIONS

Digital CDUs can be safely and effectively applied in patients after cardiac surgery. Due to the improved patient mobility and simplified chest tube management, the use of digital CDUs may be advantageous for patients after cardiac surgery. However, the issue of clotting of the tubing systems should be addressed by further technical improvements.

Novel Pre- and Postoperative Care Using Telemedicine

The use of telemedicine and telehealth services has grown exponentially over the past decade and has become increasingly relevant and necessary during the coronavirus 2019 (COVID-19) pandemic. There remains ample opportunity to electronically connect cardiothoracic surgeons with their patients during both preoperative and postoperative visits. In this review, we examine the various implementations of telemedicine within thoracic surgery and explore future applications in this quickly developing field.

Bubbles-in-the-chamber vs digital screen in chest drainage: A blind analysis of compared postoperative air leaks evaluation

BACKGROUND

Chest drainage systems are affected by intra and inter-observer variability and poor sensibility in detecting minimal or apparent air leaks.

OBJECTIVES

Overcome intra and inter-observer variability in detecting air leaks.

METHODS

After surgery, a single apical chest tube was connected to the Drentech™ PalmEVO device and air leaks were checked twice a day by observation of both bubbles-in-the-chamber and digital data.

RESULTS

On a total of 624 observations, disagreement between digital and traditional systems was recorded in 60(9.6%) cases. In 25(21.4%) patients, a disagreement was recorded. Overall, the digital evaluation influenced clinical management in 13(52%). In 10(40%) patients with temporary discordant features, the presence of high pleural fluid output led to a progressive final concordance.

CONCLUSIONS

Disagreement between traditional and digital systems in checking air leaks is not negligible. Digital systems could give advantages in making an objective assessment of air leaks, standardizing the timing of chest tube removal.

A Systematic Review of Digital vs Analog Drainage for Air Leak After Surgical Resection or Spontaneous Pneumothorax

BACKGROUND

The concerns regarding air leak after lung surgery or spontaneous pneumothorax include detection and duration. Prior studies have suggested that digital drainage systems permit shorter chest tube duration and hospital length of stay (LOS) by earlier detection of air leak cessation. We conducted a systematic review to assess the impact of digital drainage on chest tube duration and hospital LOS after pulmonary surgery and spontaneous pneumothorax.

METHODS

Ovid MEDLINE, PubMed, Embase, the Cochrane Library, Scopus, and Google Scholar were searched from inception through January 2019. We included randomized controlled trials, cohort studies, and case series of adult patients, using digital or traditional drainage devices for air leaks of either postsurgical or spontaneous pneumothorax origin.

RESULTS

Of 1,272 references reviewed, 23 articles were included. Nineteen articles addressed postoperative air leak, and four articles pertained to air leak after spontaneous pneumothorax. Thirteen studies were randomized controlled trials. Digital drainage resulted in significantly shorter chest tube duration in eight of 18 studies and shorter hospital LOS in six of 14 studies for postoperative air leak. For postpneumothorax air leak, digital drainage resulted in significantly shorter chest tube duration in two of three studies and hospital LOS in one of two studies with an analog control group.

CONCLUSIONS

Most studies show no significant differences in chest tube duration and hospital LOS with digital vs analog drainage systems for patients with air leak after pulmonary resection. For post-spontaneous pneumothorax air leak, the limited published evidence suggests shorter chest tube duration and hospital LOS with digital drainage systems.

Facing the challenges of perioperative air leaks using water seal in Colombia

Air leaks following thoracic surgery continue to be a significant cause of morbidity and mortality. In contemporary thoracic surgery, many aspects of post-surgical air leaks are still controversial. In developing countries like Colombia, state-of-the-art technology such as newer digital drainage systems are not always available, and surgeons rely primarily on water seal systems for air leak management. Although efforts are being made to increase the use of newer digital systems, being a third-world country has its challenges, and we emphasize the importance of following international guidelines as much as possible, especially when facing complex situations such as perioperative air leaks with limited resources.
