The Medical Management of Spontaneous Pneumothorax: A Concise Review

Spontaneous pneumothorax is an increasingly common clinical presentation, the management of which, until recent years, had remained unchanged for decades. A recent surge in pneumothorax research has produced the largest randomised controlled trials in the field yet and has revolutionised the management of spontaneous pneumothorax. The body of evidence supporting the introduction of conservative and ambulatory care in appropriate patients in recent guidelines now allows these patients, many of whom would otherwise have been admitted to hospital, to be managed in the outpatient setting and reduces their risk of complications compared to conventional chest drain insertion. In this review, we discuss recent advances in the management of pneumothorax and the evidence underpinning contemporary guidelines. We aim to equip physicians with the knowledge to engage their patients in the decision-making process regarding their pneumothorax, whilst keeping patient safety and patients' own preferences at the centre of their care.

Expert Review on Spontaneous Pneumothorax: Advances, Controversies, and New Directions

For decades, there has been scanty evidence, most of which is of poor quality, to guide clinicians in the assessment and management of pneumothorax. A recent surge in pneumothorax research has begun to address controversies surrounding the topic and change the face of pneumothorax management. In this article, we review controversies concerning the etiology, pathogenesis, and classification of pneumothorax, and discuss recent advances in its management, including conservative and ambulatory management. We review the evidence base for the challenges of managing pneumothorax, including persistent air leak, and suggest new directions for future research that can help provide patient-centered, evidence-based management for this challenging cohort of patients.

An evidence-based review of primary spontaneous pneumothorax in the adolescent population

Primary spontaneous pneumothorax (PSP) is a relatively common problem in emergency medicine. The incidence of PSP peaks in adolescence and is most common in tall, thin males. Recent advances in the care of patients with PSP have called into question traditional approaches to management. This clinical review highlights the changing management strategies for PSP and concludes with a proposed evidence-based pathway to guide the care of adolescents with PSP.

Unusual case of primary spontaneous hemopneumothorax in a young man with atypical tension pneumothorax: a case report

BACKGROUND

Spontaneous life-threatening hemopneumothorax is an atypical but treatable entity of unexpected circulatory collapse in young patients, affecting 0.5-11.6% of patients with primary spontaneous pneumothorax. Spontaneous pneumothorax is a well-documented disorder with a classic clinical presentation of acute onset chest pain and shortness of breath. This disorder might be complicated by the development of hemopneumothorax or tension pneumothorax.

CASE PRESENTATION

A 23-year-old Asian man was referred to the emergency room of Xiamen Chang Gung Memorial Hospital with a 1-day history of right-sided chest pain that had been aggravated for 1 hour. A physical examination revealed a young man who was awake and alert but in mild to moderate painful distress. His vital parameters were relatively stable at first. The examining physician noted slight tenderness along the right posterolateral chest wall along the eighth and tenth ribs. Primary spontaneous pneumothorax was considered, and a standing chest X-ray confirmed the diagnosis. A right thoracostomy tube was immediately placed under sterile conditions, and he was referred to the respiratory service. While in the respiratory department, approximately 420 mL of blood was drained from the thoracostomy tube over 15 minutes. Our patient developed obvious hemodynamic instability with hypovolemic shock and was subsequently admitted to the cardiothoracic surgical ward after fluid resuscitation. During the ensuing 4 hours after admission, 750 mL of blood was drained through the thoracostomy tube. A bedside chest X-ray was requested after he was temporarily hemodynamically stabilized. Primary spontaneous hemopneumothorax associated with right tension pneumothorax was considered based on the radiological impression and clinical signs. An emergency limited posterolateral thoracotomy was performed. A standing chest X-ray performed on day 6 of admission after the removal of the thoracostomy tube showed a complete re-expansion of his right lung. He remained stable and was discharged within 1 week.

CONCLUSIONS

The successful treatment of a large spontaneous hemopneumothorax depends on early recognition, proactive intervention, and early consideration by a cardiothoracic surgeon. Once the diagnosis is confirmed, early thoracotomy should be considered. Such an aggressive surgery not only leads to shorter hospitalization but also confers better long-term outcomes.

Will the presence of radiological signs of tension pneumothorax affect the clinical presentation of primary spontaneous pneumothorax?

INTRODUCTION

Patients with primary spontaneous pneumothorax (PSP) rarely presented with radiological signs of tension pneumothorax on their presenting chest X-ray. Even though, those patients may not develop the hemodynamic instability that is seen in tension pneumothorax. The aim of this study is to elaborate whether the presence of radiological signs of tension pneumothorax in patients with PSP will affect their clinical presentation.

METHODS

Retrospective study of all cases of PSP over a period from January 2007 to December 2014. The cases were divided into two groups; tension group includes cases who have radiological signs of tension pneumothorax and non-tension group who do not have those signs. The main outcome was a comparison of the hemodynamic status of both groups.

RESULTS

A total of 151 cases of PSP were included in the study. Radiologic signs of tension pneumothorax were identified in 13 cases of the sample. Only one case of the tension group developed hemodynamic instability in the form of desaturation to below 92% with no statistical difference between the two groups in maintaining the hemodynamic status.

CONCLUSION

In spite that PSP can be presented with radiological signs of tension pneumothorax, those patients usually maintained their hemodynamic stability. Tension pneumothorax rarely presented as consequence of PSP.

Spontaneous pneumothorax; a multicentre retrospective analysis of emergency treatment, complications and outcomes

BACKGROUND

Spontaneous pneumothorax can be managed initially by observation, aspiration or chest drain insertion.

AIMS

To determine the clinical features of spontaneous pneumothorax in patients presenting to the emergency department (ED), interventions, outcomes and potential risk factors for poor outcomes after treatment.

METHODS

Retrospective chart review from ED of three major referral and two general hospitals in Australia of presentations with primary spontaneous pneumothorax (PSP) or secondary spontaneous pneumothorax (SSP). Main outcomes were prolonged air leak (>5 days) and pneumothorax recurrence within 1 year.

RESULTS

We identified 225 people with PSP and 98 with SSP. There were no clinical tension pneumothoraces with hypotension. Hypoxaemia (haemoglobin oxygen saturation measured by pulse oximetry ≤92%) occurred only in SSP and in older patients (age >50 years) with PSP. Drainage was performed in 150 (67%) PSP and 82 (84%) SSP. Prolonged air leak occurred in 16% (95% confidence interval 10-23%) of PSP and 31% (21-42%) of SSP. Independent risk factors for prolonged drainage were non-asthma SSP and pneumothorax size >50%. Complications were recorded in 11% (7.5-16%) of those having drains inserted. Recurrences occurred in 5/91 (5%, 1.8-12%) of those treated without drainage versus 40/232 (17%, 13-23%) of those treated by drainage, of which half occurred in the first month after drainage.

CONCLUSION

Pneumothorax drainage is associated with substantial morbidity including prolonged air leak. As PSP appears to be well tolerated in younger people even with large pneumothoraces, conservative treatment in this subgroup may be a viable option to improve patient outcomes, but this needs to be confirmed in a clinical trial.

An unusual case of primary spontaneous tension pneumothorax in a jamaican female

Spontaneous pneumothorax is a well-recognized entity with a classical presentation of acute onset chest pain and shortness of breath. It may be complicated by the development of a tension pneumothorax or a haemopneumothorax. We report an interesting case of a spontaneous tension haemopneumothorax which presented atypically and was diagnosed on computed tomography (CT) scan of the chest. The clinical and pathophysiological characteristics and treatment of this unusual entity is discussed.
