A regional survey of chest drains: evidence-based practice?

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.

Retrospective evaluation of fluid production at the time of thoracostomy tube removal following elective and emergency surgery in dogs (2010-2017): 185 cases

OBJECTIVE

To report the rate of fluid production at the time of removal of thoracostomy tubes placed intraoperatively and to determine the association of this rate with specific patient factors, surgical factors, or clinical diagnosis. The secondary objective was to determine whether identification of pleural effusion within 2 weeks of thoracostomy tube removal was associated with the same variables.

DESIGN

Retrospective study.

SETTING

University teaching hospital.

ANIMALS

One hundred eighty-five client-owned dogs with thoracostomy tubes placed intraoperatively between January 2010 and March 2017.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Thoracostomy tubes were removed at a median fluid production of 0.09 mL/kg/h (range, 0-7.0 m L/kg/h). Median fluid production at the time of thoracostomy tube removal was significantly higher in dogs with preoperative pleural effusion compared to dogs without preoperative pleural effusion (0.21 vs 0.05 mL/kg/h; P = 0.0001) and in dogs that had a median sternotomy compared to dogs that had a lateral thoracotomy (0.14 vs 0.09 mL/kg/h; P = 0.04). Of the 169 dogs available for follow-up, 12 (7.1%) had pleural effusion within 2 weeks of removal of the thoracostomy tube. Detection of pleural effusion during the follow-up period was significantly associated with the presence of preoperative pleural effusion (P = 0.0019) and the diagnosis (P = 0.01). A greater proportion of dogs with a lung lobe torsion (4/9, 44.4%) and idiopathic chylothorax (2/7, 28.5%) had pleural effusion within 2 weeks compared to other diagnoses. Reintervention was performed in 4.7% of dogs.

CONCLUSIONS

Thoracostomy tubes were removed at pleural fluid production rates that frequently exceeded current veterinary guidelines. However, the fluid production rate at the time of thoracostomy tube removal was not associated with the detection of pleural effusion within 2 weeks of thoracostomy tube removal, and the overall need for reintervention following thoracostomy tube removal was low (4.7%).

In vitro evaluation of negative pressure generated during application of negative suction volumes by use of various syringes with and without thoracostomy tubes

OBJECTIVE

To determine the amount of negative pressure generated by syringes of various sizes with and without an attached thoracostomy tube and whether composition of thoracostomy tubes altered the negative pressure generated.

SAMPLE

Syringes ranging from 1 to 60 mL and 4 thoracostomy tubes of various compositions (1 red rubber catheter, 1 polyvinyl tube, and 2 silicone tubes).

PROCEDURES

A syringe or syringe with attached thoracostomy tube was connected to a pneumatic transducer. Each syringe was used to aspirate a volume of air 10 times. Negative pressure generated was measured and compared among the various syringe sizes and various thoracostomy tubes.

RESULTS

The negative pressure generated decreased as size of the syringe increased for a fixed volume across syringes. Addition of a thoracostomy tube further decreased the amount of negative pressure. The red rubber catheter resulted in the least amount of negative pressure, followed by the polyvinyl tube and then the silicone tubes. There was no significant difference in negative pressure between the 2 silicone tubes. The smallest amount of negative pressure generated was -74 to -83 mm Hg.

CONCLUSIONS AND CLINICAL RELEVANCE

Limited data are available on the negative pressure generated during intermittent evacuation of the thoracic cavity. For the present study, use of a syringe of ≥ 20 mL and application of 1 mL of negative suction volume resulted in in vitro pressures much more negative than the currently recommended pressure of -14.71 mm Hg for continuous suction. Additional in vitro or cadaveric studies are needed.

Variation in nurse self-reported practice of managing chest tubes: A cross-sectional study

AIMS AND OBJECTIVES

To reveal nurses' self-reported practice of managing chest tubes and to define decision-makers for these practices.

BACKGROUND

No consensus exists regarding ideal chest-tube management strategy, and there are wide variations of practice based on local policies and individual preferences, rather than standardised evidence-based protocols.

DESIGN

This article describes a cross-sectional study.

METHODS

Questionnaires were emailed to 31 hospitals in Tianjin, and the sample consisted of 296 clinical nurses whose work included nursing management of chest drains. The questionnaire, which was prepared by the authors of this research, consisted of three sections, including a total of 22 questions that asked for demographic information, answers regarding nursing management that reflected the practice they actually performed and who the decision-makers were regarding eight chest-drain management procedures. McNemar's test was used to analyse the data.

RESULTS

The results indicated that most respondents thought that it was necessary to manipulate chest tubes to remove clots impeding unobstructed drainage (91.2%). Most respondents indicated that dressings would be changed when the dressing was dysfunctional. At the same time, more than half of respondents approved of changing dressings routinely, and the frequency of changing dressings varied. When drainage was employed for pleural effusion and for a pneumothorax, 64.6% and 94.5% of respondents, respectively, considered that underwater seal-drainage bottles should be changed routinely, and the frequency of changing bottles both varied. The results indicated that nurses were the primary decision-makers in the replacement of chest tubes, manipulation of chest tubes and monitoring of drainage fluid.

CONCLUSIONS

There was considerable variation in respondents' self-reported clinical nursing practice regarding management of chest drains. The rationale on which respondents' practices were based also varied greatly. This study indicated that nurses were the primary decision-makers for three of eight procedures regarding management of chest drains, which reflects that clinical nurses' decision-making power regarding management of chest drains was weak.

RELEVANCE TO CLINICAL PRACTICE

This study describes the nurse-reported practices of Chinese nurses from Tianjin, including changing and selecting dressing types, manipulating chest tubes, clamping drains and replacing drainage bottles, and the study defines who the decision-makers were for these interventions. By focusing on nurses' self-report of behaviours in managing chest drains (actual nursing practice vs. nursing knowledge), this article also relates the literature to the research findings and denotes the gaps in knowledge for future research.

Do X-rays after chest tube removal change patient management?

BACKGROUND

A link between childhood radiation and future cancer risks exists, and reduction of unnecessary radiation in childhood has been recommended. Pneumothoraces, pleural effusions, and many surgical procedures require placement of a chest tube/pigtail catheter. Traditional management is daily x-rays, with an x-ray after tube removal. Our hypothesis is the "post pull" x-ray rarely results in changing clinical management of the patient.

METHODS

With IRB approval, a 5-year retrospective chart review was performed. Inclusion criteria were chest tube or pigtail placed for any reason with complete records. Data collected were demographics, reason for and duration of placement, number of x-rays done prior to and after removal. Primary outcome was whether the "post pull" x-ray changed clinical management.

RESULTS

A total of 179 episodes were evaluated. Seventeen were excluded for incomplete data, or death/transfer of the patient with the tube in situ. Forty-nine tubes/pigtails were placed for pneumothorax, 48 for pleural effusion/empyema, 9 for hemothorax, and 51 during operative procedure. A median of 5 x-rays was done post insertion. 99% of the patients (160/162) had a "post pull" x-ray performed after tube removal. In 9 cases the x-ray changed patient management.

CONCLUSIONS

X-ray after chest tube/pigtail removal rarely changes patient management. We recommend considering imaging if there are clinical symptoms.

Determining optimal fluid and air leak cut off values for chest drain management in general thoracic surgery

BACKGROUND

Chest drain duration is one of the most important influencing aspects of hospital stay but the management is perhaps one of the most variable aspects of thoracic surgical care. The aim of our study is to report outcomes associated with increasing fluid and air leak criteria of protocol based management.

METHODS

A 6-year retrospective analysis of protocolised chest drain management starting in 2007 with a fluid criteria of 3 mL/kg increasing to 7 mL/kg in 2011 to no fluid criteria in 2012, and an air leak criteria of 24 hours without leak till 2012 when digital air leak monitoring was introduced with a criteria of <20 mL/min of air leak for more than 6 hours. Patient data were obtained from electronic hospital records and digital chest films were reviewed to determine the duration of chest tube drainage and post-drain removal complications.

RESULTS

From 2009 to 2012, 626 consecutive patients underwent thoracic surgery procedures under a single consultant. A total of 160 did not require a chest drain and data was missing in 22, leaving 444 for analysis. The mean age [standard deviation (SD)] was 57±19 years and 272 (61%) were men. There were no differences in the incidence of pneumothoraces (P=0.191), effusion (P=0.344) or re-interventions (P=0.431) for drain re-insertions as progressively permissive criteria were applied. The median drain duration dropped from 1-3 days (P<0.001) and accordingly hospital stay reduced from 4-6 days (P<0.001).

CONCLUSIONS

Our results show that chest drains can be safely removed without fluid criteria and air leak of less than 20 mL/min with median drain duration of 1 day, associated with a reduced length of hospital stay.

Correlation between ATLS training and junior doctors' anatomical knowledge of intercostal chest drain insertion

OBJECTIVE

To review the ability of junior doctors (JDs) in identifying the correct anatomical site for intercostal chest drain insertion and whether prior Advanced Trauma Life Support (ATLS) training influences this.

DESIGN

We performed a prospective, observational study using a structured survey and asked a group of JDs (postgraduate year 1 [PGY1] or year 2 [PGY2]) to indicate on a photograph the exact preferred site for intercostal chest drain insertion.

SETTING

This study was conducted in a large metropolitan university hospital in South Africa.

RESULTS

A total of 152 JDs participated in the study. Among them, 63 (41%) were men, and the mean age was 24 years. There were 90 (59%) PGY1 doctors and 62 (41%) PGY2 doctors. Overall, 28% (42/152) of all JDs correctly identified the site that was located within the accepted safe triangle. A significantly higher proportion of PGY2 doctors selected the correct site when compared with PGY1 doctors (39% vs 20%, p = 0.026). Those who had prior ATLS provider training were 6.8 times more likely to be able to identify the correct site (RR = 6.8, 95% CI: 3.7-12.5).

CONCLUSIONS

Most of the JDs do not have sufficient anatomical knowledge to identify the safe insertion site for intercostal chest drain. Those who had undergone ATLS training were more likely to be able to identify the safe insertion site.

Results of thoracic drainages placed in air rescue

INTRODUCTION

horax injuries are to be found in approximately 78% amongst all accident victims. Moreover, they implicate an increase in mortality rate. Consequently, an adequate contemporary treatment has to begin preclinically, even if the conditions are less comfortable than in a clinical setting. Emergency doctors need to be familiar with the placement of chest tubes.

MATERIALS AND METHODS

From January 1, 2007 to December 31, 2010, emergency doctors of the rescue helicopter site Christoph 20 had to place chest tubes directly at the scene of an accident in 49 patients. These patients were now reidentified, and their clinical course was reevaluated. By means of apparative diagnostics, it was possible to analyze the location of the tubes tip. Following a comparison of the patient, outcome versus the quality of preclinical thoracic discharge could be made.

RESULTS

The preclinical placement of a chest tube became necessary mainly because of a blunt thoracic trauma. This was predominantly related to victims of traffic accidents, whereas male victims clearly dominated. Forty-two of those patients received further treatment at the Klinikum Bayreuth hospital, enabling an analysis of the tubes location by CAT (computed axial tomography) scan. Six patients had been discharged on both sides, contributing to 48 tube tips that could be examined concerning their location. Of the 48 chest tubes, 46 had been placed from a lateral approach. The ventral access by Monaldi had only been chosen in two cases. Altogether, nine incorrect placements, mainly within the right interlobe gap, had been detected.

CONCLUSIONS

The study collective showed a significant preference to the lateral approach when placing a chest tube at the emergency scene of an accident. In total, a prevalence of 19% incorrect placements could be revealed, meaning the chest tube had either been placed within the lung parenchyma, the interlobe gap, or extrathoracically. Concerning the patient outcome, no statistically significant difference regarding the clinical course after incorrect chest tube placement could be identified.

The rate of pleural fluid drainage as a criterion for the timing of chest tube removal: theoretical and practical considerations

Clinicians place chest tubes approximately 1 million times each year in the United States, but little information is available to guide their management. Specifically, use of the rate of pleural fluid drainage as a criterion for tube removal is not standardized. Absent such tubes, pleural fluid drains primarily through parietal pleural lymphatics at rates approaching 500 mL of fluid per day or more for each hemithorax. Early removal of tubes does not appear to be harmful. A noninferiority randomized trial currently in progress comparing removal without considering the drainage rate to a conservative threshold (2 mL/kg body weight in 24 hours) may better inform tube management.

Nurses' knowledge of chest drain management in an Irish Children's Hospital

AIMS AND OBJECTIVES

To explore contact with and knowledge regarding chest drain management among nurses.

BACKGROUND

Chest drains are commonly used in both adult and paediatric settings, for example, for cardiothoracic patients or postspinal surgery, where they are inserted intra-operatively to drain excess fluid. Despite a large number of children requiring chest drain insertion annually, current literature suggests that many nurses have reduced contact with chest drains and a knowledge deficit regarding their management. Furthermore, the literature is limited in relation to chest drain management in the paediatric patient. Mismanagement of chest drains can have devastating consequences for patients.

DESIGN

A standardised descriptive survey approach was employed.

METHODS

The sample consisted of 121 critical care and ward nurses from a large urban paediatric hospital, who cared for chest drains on a regular basis. Data were collected using a 37-item questionnaire, adapted from a study in the adult setting. Statistical analysis was performed using spss V15.

RESULTS

The findings demonstrate that increased exposure to caring for children with chest drains is synonymous with a greater perception of knowledge levels in this area of practice. While critical care nurses looked after children with chest drains more frequently than ward nurses, there was no difference in the knowledge assessment section of the questionnaire. This research identified where knowledge deficits exist.

CONCLUSIONS

This study identified the key areas where overall uncertainties existed leading to a decreased knowledge perception. Nurses are engaging with methods of knowledge acquisition; however, those who have less contact with chest drains require regular updates.

RELEVANCE TO CLINICAL PRACTICE

Addressing misconceptions about chest drain management is imperative. Providing up to date guidelines in clinical areas will improve chest drain management. Strategic educational initiatives are in place to ensure identified knowledge deficits are addressed and a complete revision of chest drain guidelines has been undertaken.

The need for nurses to have in service education to provide the best care for clients with chest drains

Chest drains are a widespread intervention for patients admitted to acute respiratory or cardiothoracic surgery care areas. These are either inserted intraoperatively or as part of the conservative management of a respiratory illness or thoracic injury. Anecdotally there appears to be a lack of consensus among nurses on the major principles of chest drain management. Many decisions tend to be based on personal factors rather than sound clinical evidence. This inconsistency of treatment regimes, together with the lack of evidence-based nursing care, creates a general uncertainty regarding the care of patients with chest drains. This study aimed to identify the nurses' levels of knowledge with regard to chest drain management and identify and to ascertain how nurses keep informed about the developments related to the care of patients with chest drains. The data were collected using survey method. The results of the study revealed deficits in knowledge in a selected group of nurses and a paucity of resources. Nurse managers are encouraged to identify educational needs in this area, improve resources and the delivery of in service and web-based education and to encourage nurses to reflect upon their own knowledge deficits through portfolio use and ongoing professional development.

The normative distribution of chest tube drainage volume after coronary artery bypass grafting

BACKGROUND

Little evidence exists to describe expected volumes of chest tube (CT) drainage after coronary artery bypass grafting (CABG).

OBJECTIVES

The study objective was to map the trajectory of CT drainage volumes from insertion to removal after CABG.

DESIGN

This was a retrospective, descriptive study.

PATIENTS

The study included 239 patients who underwent CABG at a single metropolitan hospital in Melbourne, Australia.

RESULTS

The sample (N = 234), aged 68.7 years (standard deviation [SD] 9.9), was predominantly male (N = 185, 79.1%). The mean duration of CT insertion was 45.2 hours (SD 26.7), and total drainage volume was 1300.6 mL (SD 763.8). Drainage volumes plateau to 31 mL per hour, 8 hours after surgery. From 24 to 48 hours, the mean drainage was 21 mL per hour. Drainage volumes varied between genders.

CONCLUSIONS

Evidence of similar drainage patterns in other populations is difficult to locate. If the pattern of drainage shown in this study is consistent, experimental intervention studies comparing standard removal time and earlier removal are recommended. If not, prospective collection of relevant preoperative, intraoperative, and postoperative factors across multiple sites is necessary to determine which patient or practice variations influence CT drainage patterns after CABG.

Pre-hospital pleural decompression and chest tube placement after blunt trauma: A systematic review

Pre-hospital insertion of chest tubes or decompression of air within the pleural space is one of the controversial topics in emergency medical care of trauma patients. While a wide variety of opinions exist medical personnel on the scene require guidance in situations when tension pneumothorax or progressive pneumothorax is suspected. To ensure evidence based decisions we performed a systematic review of the current literature with respect to the diagnostic accuracy in the pre-hospital setting to identify patients with (tension) pneumothorax, the efficacy and safety of performing pleural decompression in the field and the choice of method and technique for the procedure. The evidence found is presented and discussed and recommendations are drawn from the authors' perspective.

Nurses’ knowledge of chest drain care: an exploratory descriptive survey

Chest drains are a common feature of patients admitted to acute respiratory or cardio-thoracic surgery care areas. Chest drains are either inserted intraoperatively or as part of the conservative management of a respiratory illness or thoracic injury. Anecdotally, there appears to be a lack of consensus among nurses on the major principles of chest drain management. Many decisions tend to be based on personal factors rather than sound clinical evidence. This inconsistency of treatment regimes, together with the lack of evidence-based nursing care, creates a general uncertainty regarding the care of patients with chest drains. This study aimed to identify the nurses' levels of knowledge with regard to chest drain management. The research objective of this study was to describe the nurses' levels of knowledge regarding the care of the patient with chest drains. The data were collected using survey method. The results of the study revealed deficits in knowledge in a select group of nurses. Several service-led options exist with regard to improving knowledge in this area, such as service study days as well as ward-based tutorials. However, in an era of increasing accountability together with the impetus for each nurse to provide evidence-based care, it is crucial for individual nurse responsibility in the pursuit of knowledge in this area. Nurses must be supported by local practice development and through personal portfolio use to identify gaps in knowledge and seek appropriate training and resources.

A new specifically designed forceps for chest drain insertion

Insertion of a chest drain can be associated with serious complications. It is recommended that the drain is inserted with blunt dissection through the chest wall but there is no specific instrument to aid this task. We describe a new reusable forceps that has been designed specifically to facilitate the insertion of chest drains.A feasibility study of its use in patients who required a chest drain as part of elective cardiothoracic operations was undertaken. The primary end-point was successful and accurate placement of the drain. The operators also completed a questionnaire rating defined aspects of the procedure. The new instrument was used to insert the chest drain in 30 patients (19 male, 11 female; median age 61.5 years (range 16-81 years)). The drain was inserted successfully without the trocar in all cases and there were no complications. Use of the instrument rated as significantly easier relative to experience of previous techniques in all specified aspects. The new device can be used to insert intercostal chest drains safely and efficiently without using the trocar or any other instrument.

When to remove a chest tube? A randomized study with subsequent prospective consecutive validation

BACKGROUND

Operative procedures on the pleural space are usually managed by chest tube drainage. Timing for removing the tube is empirically established, with wide variation among surgeons. Our objective was to evaluate the effectiveness and safety of establishing a volume of 200 mL/d of uninfected drainage as a threshold for removal of chest tube, as compared with more frequently used volumes of 100 and 150 mL/d.

STUDY DESIGN

A prospective randomized study was performed in a single institution. Patients (n = 139) submitting to pleural drainage after surgical procedures were randomized to one of three groups, defined by the planned timing of chest tube removal (depending on the threshold volume per day of pleural fluid drained): G-100 (< or = 100 mL/d, n = 44); G-150 (< or =150 mL/d, n = 58); and G-200 (< or = 200 mL/d, n = 37). Subsequently, another 91 consecutive patients had chest tubes removed when drainage was less than 200 mL/d (G-val, prospective validation group). All patients had similar discharge and 60-day followup. Drainage time, hospital stay, and reaccumulation rate were registered.

RESULTS

Drainage time (median days: 3.5 for G-100, 3 for G-150, 3 for G-200, 3 for G-val) and hospital stay (median days: 4 for G-100, 3 for G-150, 3 for G-200, 3 for G-val) were not statistically different among groups. Radiologic reaccumulation rates were 9.1% for G-100, 13.1% for G-150, 5.4% for G-200, and 10.9% for G-val, and the thoracenteses rates were 2.3%, 0.8%, 2.7%, and 3.3%, respectively, with no major differences among groups (G-100 versus G-150 versus G-200; G-200 versus G-val).

CONCLUSIONS

Increasing the threshold of daily drainage to 200 mL before removing the chest tube did not markedly affect drainage, hospitalization time, or overall costs, nor did it increase the likelihood of major pleural fluid reaccumulation. This volume (200 mL/d) could be recommended for chest tube withdrawal decision for uninfected pleural fluid with no evidence of air leaks.

An evidence-based approach to drainage of the pleural cavity: evaluation of best practice

Recent surveys have uncovered major variations in key aspects of intercostal drain management, suggesting that decisions are being made on individual preferences without resorting to sound evidence. We provide an up-to-date review of the best practice with evidence-based recommendations and expert consensus views. The following aspects of chest drain management have been addressed: indications for drainage, insertion technique, complications, management of an indwelling chest drain, indications and technique for removal. The emphasis in this review is that safe intercostal drain practice relies upon adherence to a few important principles. Furthermore, when in doubt, particularly with a complex thoracic problem, one should seek prompt specialist advice.
