Sternal haematoma infusion catheter: a novel technique for pain management in manubriosternal fractures in the emergency department.

Sternal fractures are associated with significant morbidity and mortality, with some patients requiring admission for pain management, often through systemic analgesia, which may be ineffective. Regional anaesthetic techniques are more challenging for sternal fractures than rib fractures and require experienced clinicians. Local anaesthetic techniques are becoming recognised as a modality to improve pain control and to reduce complications from opioid use, especially in the elderly. We delivered local anaesthetic via a sternal haematoma infusion catheter for an elderly patient with uncontrolled pain despite the provision of intravenous patient-controlled analgesia. This technique enabled an improvement in pain scores, better engagement with physiotherapy and reduced opioid use. Local anaesthesia has been used previously to manage pain after coronary artery bypass graft surgery. Our experience demonstrated the safety, efficacy and tolerability of this approach to analgesia in sternal fractures.

Occult tension pneumothorax discovered following imaging for adult trauma patients in the modern major trauma system: a multicentre observational study.

BACKGROUND: Tension pneumothorax following trauma is a life-threatening emergency and radiological investigation is normally discouraged prior to treatment in traditional trauma doctrines such as ATLS. Some trauma patients may be physiologically stable enough for diagnostic imaging and occult tension pneumothorax is discovered radiologically. We assessed the outcomes of these patients and compared them with those with clinical diagnosis of tension pneumothorax prior to imaging. METHODS: A multicentre civilian-military collaborative network of six major trauma centres in the UK collected observational data from adult patients who had a diagnosis of traumatic tension pneumothorax during a 33-month period. Patients were divided into 'radiological' (diagnosis following CT/CXR) or 'clinical' (no prior CT/CXR) groups. The effect of radiological diagnosis on survival was analysed using multivariable logistic regression that included the covariates of age, gender, comorbidities and Injury Severity Score. RESULTS: There were 133 patients, with a median age of 41 (IQR 24-61); 108 (81%) were male. Survivors included 49 of 59 (83%) in the radiological group and 59 of 74 (80%) in the clinical group (p=0.487). Multivariable logistic regression showed no significant association between radiological diagnosis and survival (OR 2.40, 95% CI 0.80 to 7.95; p=0.130). There was no significant difference in mortality between the groups. CONCLUSION: Radiological imaging may be appropriate for selected trauma patients at risk of tension pneumothorax if they are considered haemodynamically stable. Trauma patients may be physiologically stable enough for radiological imaging but have occult tension pneumothorax because they did not have the typical clinical presentation. The historical dogma of the 'forbidden scan' no longer applies to such patients.
