Outpatient management of primary spontaneous pneumothorax in the emergency department of a community hospital using a small-bore catheter and a Heimlich valve

Methods of measurement for pneumothorax in pediatric patients: a systematic review

Accurate measurement of pneumothorax (PTX) size is necessary to guide clinical decision making; however, there is no consensus as to which method should be used in pediatric patients. This systematic review seeks to identify and evaluate the methods used to measure PTX size with CXR in pediatric patients. A systematic review of the literature through 2021 following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was conducted using the following databases: Ovid/MEDLINE, Scopus, Cochrane Database of Controlled Trials, Cochrane Database of Systematic Reviews, and Google Scholar. Original research articles that included pediatric patients (< 18 years old) and outlined the PTX measurement method were included. 45 studies were identified and grouped by method (Kircher and Swartzel, Rhea, Light, Collins, Other) and societal guideline used. The most used method was Collins (n = 16; 35.6%). Only four (8.9%) studies compared validated methods. All found the Collins method to be accurate. Seven (15.6%) studies used a standard classification guideline and 3 (6.7%) compared guidelines and found significant disagreement between them. Pediatric-specific measurement guidelines for PTX are needed to establish consistency and uniformity in both research and clinical practice. Until there is a better method, the Collins method is preferred.

SPLF/SMFU/SRLF/SFAR/SFCTCV Guidelines for the management of patients with primary spontaneous pneumothorax

INTRODUCTION

Primary spontaneous pneumothorax (PSP) is the presence of air in the pleural space, occurring in the absence of trauma and known lung disease. Standardized expert guidelines on PSP are needed due to the variety of diagnostic methods, therapeutic strategies and medical and surgical disciplines involved in its management.

METHODS

Literature review, analysis of the literature according to the GRADE (Grading of Recommendation, Assessment, Development and Evaluation) methodology; proposals for guidelines rated by experts, patients and organizers to reach a consensus. Only expert opinions with strong agreement were selected.

RESULTS

A large PSP is defined as presence of a visible rim along the entire axillary line between the lung margin and the chest wall and ≥ 2 cm at the hilum level on frontal chest X-ray. The therapeutic strategy depends on the clinical presentation: emergency needle aspiration for tension PSP; in the absence of signs of severity: conservative management (small PSP), needle aspiration or chest tube drainage (large PSP). Outpatient treatment is possible if a dedicated outpatient care system is previously organized. Indications, surgical procedures and perioperative analgesia are detailed. Associated measures, including smoking cessation, are described.

CONCLUSION

These guidelines are a step towards PSP treatment and follow-up strategy optimization in France.

Recommandations formalisées d’experts pour la prise en charge des pneumothorax spontanés primaires

Introduction : Le pneumothorax spontané primaire (PSP) est un épanchement gazeux dans la cavité pleurale, survenant hors traumatisme et pathologie respiratoire connue. Des recommandations formalisées d'experts sur le sujet sont justifiées par les pluralités de moyens diagnostiques, stratégies thérapeutiques et disciplines médicochirurgicales intervenant dans leur prise en charge.

Méthodes : Revue bibliographique, analyse de la littérature selon méthodologie GRADE (Grading of Recommendation Assessment, Development and Evaluation) ; propositions de recommandations cotées par experts, patients et organisateurs pour obtenir un consensus. Seuls les avis d'experts avec accord fort ont été retenus.

Résultats : Un décollement sur toute la hauteur de la ligne axillaire et supérieur ou égal à 2 cm au niveau du hile à la radiographie thoracique de face définit la grande abondance. La stratégie thérapeutique dépend de la présentation clinique : exsufflation en urgence pour PSP suffocant ; en l'absence de signe de gravité : prise en charge conservatrice (faible abondance), exsufflation ou drainage (grande abondance). Le traitement ambulatoire est possible si organisation en amont de la filière. Les indications, procédures chirurgicales et l'analgésie périopératoire sont détaillées. Les mesures associées, notamment le sevrage tabagique, sont décrites.

Conclusion : Ces recommandations sont une étape de l'optimisation des stratégies de traitement et de suivi des PSP en France.

Ambulant treatment with a digital chest tube for prolonged air leak is safe and effective

Background

Outpatient or ambulatory treatment for prolonged air leak (PAL) has been reported previously in various studies. Evidence regarding efficiency and safety is nevertheless poor. This report describes the experience of 10 years ambulatory care with a digital chest drain system monitored by specialized nurses in our centre. The aim of the study is to give further insights in the effectiveness and safety of this treatment.

Methods

Retrospective data of 10 years ambulatory care for PAL were examined. One hundred and forty patients with PAL after pneumothorax or pulmonary surgery were included.

Results

A total of 140 patients with PAL were included. Treatment was successful in 112 patients (80.0%). Hospital readmission was necessary in 33 patients (23.6%) and 28 (20.0%) of them received additional treatment. Additional treatment consisted of video-assisted thoracoscopic surgery (VATS) in 19 patients (13.6%), new chest tube placement in 8 patients (5.7%) and pleurodesis (with talc slurry) in 1 patient (0.7%). Minor complications occurred in 10 patients (7.1%), major complications requiring readmission occurred in 14 patients (10.0%).

Conclusions

Ambulatory treatment of PAL with a digital monitoring device resulted in a high success rate with a limited complication rate.

Effectiveness of Bedside Lung Ultrasound for Clinical Follow-Up of Primary Spontaneous Pneumothorax Patients Treated With Tube Thoracostomy

Primary spontaneous pneumothorax (PSP) is a common cause of presentation to emergency departments and subsequent hospitalization. Patients with large PSP are treated with tube thoracostomy (TT) and followed up with x-rays. In this study, we investigated the efficiency of bedside ultrasound and compared it with x-ray imaging for the clinical follow-up of PSP patients treated with TT.This is a prospective observational study. After ethical committee approval and written informed consent were obtained, patients who were treated with TT because of PSP were screened. In the follow-up of these patients, a bedside lung ultrasound (BLUS) was performed before every chest x-ray by an emergency physician experienced in performing BLUSs. The performance of BLUSs in detecting free air in the pleural cavity was compared statistically with that of x-rays.Sixty-two patients were enrolled in the study. In total, 166 BLUSs and x-rays were compared. The sensitivity of BLUS was 95.65% (85.20-99.50), specificity was 100% (79.40-100.00), positive predictive value was 100% (92-100), negative predictive value was 88.90% (65.30-98.60), and the area under the curve was 0.99 (0.974-1.000; P = 0.001) for detecting air in the pleural cavity. These results showed that there was no statistically significant difference between BLUS and x-ray methods for detecting air in the pleural cavity.Our study revealed that BLUS can be safely used for the follow-up of PSP patients treated with TT to determine if air is present in the pleural cavity. Further studies are needed.

How spontaneous pneumothorax is managed in emergency departments: a French multicentre descriptive study

Background

Management of spontaneous pneumothorax (SP) is still subject to debate. Although encouraging results of recent studies about outpatient management with chest drains fitted with a one-way valve, no data exist concerning application of this strategy in real life conditions. We assessed how SP are managed in Emergency departments (EDs), in particular the role of outpatient management, the types of interventions and the specialty of the physicians who perform these interventions.

Methods

From June 2009 to May 2013, all cases of spontaneous primary (PSP) and spontaneous secondary pneumothorax (SSP) from EDs of 14 hospitals in France were retrospectively included. First line treatment (observation, aspiration, thoracic drainage or surgery), type of management (admitted, discharged to home directly from the ED, outpatient management) and the specialty of the physicians were collected from the medical files of the ED.

Results

Among 1868 SP included, an outpatient management strategy was chosen in 179 PSP (10%) and 38 SSP (2%), mostly when no intervention was performed. Only 25 PSP (1%) were treated by aspiration and discharged to home after ED admission. Observation was the chosen strategy for 985 patients (53%). In 883 patients with an intervention (47%), it was performed by emergency physicians in 71% of cases and thoracic drainage was the most frequent choice (670 patients, 76%).

Conclusions

Our study showed the low level of implementation of outpatient management for PS in France. Despite encouraging results of studies concerning outpatient management, chest tube drainage and hospitalization remain preponderant in the treatment of SP.

Management of primary spontaneous pneumothorax: a review

Primary spontaneous pneumothorax is a common problem faced by doctors in medical practice. It is a significant global health problem affecting adolescent and young adults. This article will review the etiopathology, diagnosis and current management guidelines. It aims to improve clinical practice and compliance to the complexities of procedures involved in management.

ERS task force statement: diagnosis and treatment of primary spontaneous pneumothorax

Primary spontaneous pneumothorax (PSP) affects young healthy people with a significant recurrence rate. Recent advances in treatment have been variably implemented in clinical practice. This statement reviews the latest developments and concepts to improve clinical management and stimulate further research.The European Respiratory Society's Scientific Committee established a multidisciplinary team of pulmonologists and surgeons to produce a comprehensive review of available scientific evidence.Smoking remains the main risk factor of PSP. Routine smoking cessation is advised. More prospective data are required to better define the PSP population and incidence of recurrence. In first episodes of PSP, treatment approach is driven by symptoms rather than PSP size. The role of bullae rupture as the cause of air leakage remains unclear, implying that any treatment of PSP recurrence includes pleurodesis. Talc poudrage pleurodesis by thoracoscopy is safe, provided calibrated talc is available. Video-assisted thoracic surgery is preferred to thoracotomy as a surgical approach.In first episodes of PSP, aspiration is required only in symptomatic patients. After a persistent or recurrent PSP, definitive treatment including pleurodesis is undertaken. Future randomised controlled trials comparing different strategies are required.

Global Emergency Medicine Journal Club: A Social Media Discussion About the Outpatient Management of Patients With Spontaneous Pneumothorax by Using Pigtail Catheters

Annals of Emergency Medicine collaborated with an educational Web site, Academic Life in Emergency Medicine (ALiEM) to host a public discussion featuring the 2014 Annals article on the outpatient management of patients with a spontaneous pneumothorax by using pigtail catheters. The objective was to curate a 14-day (November 10 to 23, 2014) worldwide academic dialogue among clinicians about the article. Four online facilitators hosted the multimodal discussion on the ALiEM Web site, Twitter, and Google Hangout. Comments across the social media platforms were curated for this report, as framed by 4 preselected questions. Engagement was tracked through Web analytic tools. Blog comments, tweets, and video expert commentary involving the featured article are summarized and reported. The dialogue resulted in 1,023 page views from 347 cities in 49 countries on the ALiEM Web site, 279,027 Twitter impressions, and 88 views of the video interview with experts. This Global Emergency Medicine Journal Club created a virtual community of practice from around the world and identified common themes around the management of spontaneous pneumothorax, which included substantial practice variation in regard to inpatient versus outpatient management, location of chest tube, the use of aspiration, and chest radiography after placement.

Ambulatory treatment in the management of pneumothorax: a systematic review of the literature

INTRODUCTION

Spontaneous pneumothorax (SP) is broken down into primary (PSP: no known underlying lung disease), secondary (SSP: known lung disease) and from trauma or iatrogenic pneumothorax (IP). Current treatments include a conservative approach, needle aspiration, chest drain, suction and surgery. A Heimlich valve (HV) is a lightweight one-way valve designed for the ambulatory treatment of pneumothorax (with an intercostal catheter).

METHODS

We performed a systematic review across nine electronic databases for studies reporting the use of HV for adults with pneumothorax. Randomised controlled trials (RCT), case control studies and case series were included, unrestricted by year of publication. Measures of interest included the use only of a HV to manage SP or IP, (ie, avoidance of further procedures), successful treatment as outpatient (OP) and complications.

RESULTS

Eighteen studies were included reporting on the use of HV in 1235 patients, 992 cases of SP (of which 413 were reported as PSP) and 243 IP. The overall quality of the reports was moderate to poor with high risk of bias. Success with HV alone was 1060/1235 (85.8%) and treatment as OP successful in 761/977 (77.9%). Serious complications are rare. Long-term outcomes are comparable with current treatments.

CONCLUSIONS

High-quality data to support the use of HV for ambulatory treatment of pneumothorax is sparse. The use of HV in such circumstances may have benefits for patient comfort, mobility and avoidance of hospital admission, with comparable outcomes to current practice. There is urgent need for a carefully designed RCT to answer his question.

Critical procedures in pediatric emergency medicine

Children comprise approximately one-quarter of all visits to most emergency departments. Children are generally healthier than adults, yet there are similar priorities in assessment and management of pediatric patients. The initial approach to airway, breathing, and circulation still applies and is first and foremost in the evaluation of young infants and children. There are certain anatomic, physiologic, developmental, and social considerations that are unique to this population and must be taken into account during their evaluation and treatment. In this review, we present and discuss an evidence-based approach to high-yield procedures necessary for all emergency physicians taking care of children.

The frequency of reexpansion pulmonary edema after trocar and hemostat assisted thoracostomy in patients with spontaneous pneumothorax

PURPOSE

Several risk factors for development of reexpansion pulmonary edema (REPE) after drainage of pneumothoraces have been reported, but the association between the method of thoracostomy and the development of REPE is unknown. The aim of this study was to compare the frequency of REPE after treatment of spontaneous pneumothorax with trocar or hemostat assisted closed thoracostomy.

MATERIALS AND METHODS

We performed a prospective, observational study including 173 patients with spontaneous pneumothorax who visited the emergency department from January 2007 to December 2008. In 2007, patients were treated with hemostat-assisted drainage, whereas patients in 2008 were treated with trocar-assisted drainage. The main outcome was the development of REPE, determined by computed tomography of the chest 8 hours after closed thoracostomy. Outcomes in both groups were compared using univariate and multivariate analyses.

RESULTS

Ninety-two patients were included, 48 (42 males) of which underwent hemostat-assisted drainage and 44 (41 males) underwent trocar-assisted drainage. The groups were similar in mean age (24 ± 10 vs. 26 ± 14 respectively). The frequencies of REPE after hemostat- and trocar-assisted drainage were 63% (30 patients) and 86% (38 patients) respectively (p=0.009). In multivariate analysis, trocar-assisted drainage was the major contributing factor for developing REPE (odds ratio=5.7, 95% confidence interval, 1.5-21). Age, gender, size of pneumothorax, symptom duration and laboratory results were similar between the groups.

CONCLUSION

Closed thoracostomy using a trocar is associated with an increased risk of REPE compared with hemostat- assisted drainage in patients with spontaneous pneumothorax.

Pediatric spontaneous pneumothorax

Spontaneous pneumothorax (SP) occurs when air enters the pleural space in the absence of a traumatic or iatrogenic etiology and is an uncommon phenomenon in the pediatric population. Although the typical presentation has been well described in the literature, much debate still surrounds the epidemiology, pathophysiology, diagnosis, and management of this condition in the pediatric population. To date, much of the emphasis in the pediatric literature has been on surgical options. Questions still remain regarding the true incidence of this disease in children, appropriate diagnostic imaging, and treatment recommendations for practitioners in the emergency department setting. This review of the evidence seeks to elaborate on current knowledge and clinical practice, as well as the applicability of adult recommendations to the pediatric population.

Pleural disease in the emergency department

Emergency department presentations of pleural-based diseases are common, with severity ranging from mild to life threatening. The acute assessment, diagnosis, and treatment of pleural disease are critical as urgent invasive maneuvers such as thoracocentesis and thoracostomy may be indicated. The emergency physician must have a systematic approach to these conditions that allows for rapid recognition, diagnosis, and definitive management. This article focuses on nontraumatic pleural disease, including diagnostic and treatment considerations of pleural effusion, empyema, primary spontaneous pneumothorax, secondary spontaneous pneumothorax, pediatric pneumothorax, spontaneous hemothorax, and spontaneous tension pneumothorax.

Portable chest drainage systems and outpatient chest tube management

Ambulatory treatment of pleural problems such as pneumothorax and malignant pleural effusions has been extensively described and is commonly used. On the contrary, outpatient management of chest tubes after lung resection is less frequently performed. Because prolonged air leak after lobectomy is a common problem, early discharge of these patients under pleural drainage can avoid many hospital days without compromising the quality of care. In this article, general rules for outpatient chest tube management are described and available portable devices are reviewed.
