Fulltext The Macklin effect--pneumomediastinum and pneumopericardium following blunt chest trauma

Med J Malaysia, 2006 Aug;61(3):371-3.

Pneumomediastinum and pneumopericardium following blunt chest trauma are rare. Diagnosis is by chest radiograph and CT Scan. They have to be identified and treated accordingly. Usually, pneumomediastinum and pneumopericardium are self-limiting requiring no specific therapy. However, vigilance and a continuous monitoring of the vital signs are necessary.

A 21-year-old primigravida with previous history of pulmonary tuberculosis had a normal but assisted vaginal delivery after a prolonged second stage. Within 12 hours, she complained of dyspnoea and was found to have abnormal neck and anterior chest wall swelling. A diagnosis of subcutaneous emphysema was made and this was confirmed with the chest radiograph, which also revealed pneumomediastinum. She recovered well within four days with conservative treatment.

Subcutaneous emphysema and pneumomediastinum after endotracheal anaesthesia

Chiu CL, Ong GS

Ann Acad Med Singap, 2000 Mar;29(2):256-8.

PMID: 10895351

INTRODUCTION: We report a case of subcutaneous emphysema and pneumomediastinum that presented postoperatively after tracheal extubation.

CLINICAL PICTURE: A 51-year-old man had an uneventful anaesthesia lasting about 6.5 hours. Intubation was performed by a very junior medical officer and was considered difficult. He developed sore throat, chest pain, numbness of both hands and palpable crepitus around the neck postoperatively. Chest X-ray revealed diffuse subcutaneous emphysema, pneumomediastinum and possible pneumopericardium.

TREATMENT: He was treated conservatively with bed rest, oxygen, analgesia, antibiotic prophylaxis, reassurance and close monitoring.

OUTCOME: The patient made an uneventful recovery.

CONCLUSIONS: We discussed the possible causes.

Fulltext Silicone Y-stent insertion under extracorporeal membrane oxygenation (ECMO) in a patient with tracheal tear

Tracheal tear after endotracheal intubation is extremely rare. The role of silicone Y-stent in the management of tracheal injury has been documented in the previous studies. However, none of the studies have mentioned the deployment of silicone Y-stent via rigid bronchoscope with the patient solely supported by extracorporeal membrane oxygenation (ECMO) without general anaesthesia delivered via the side port of the rigid bronchoscope. We report a patient who had a tracheal tear due to endotracheal tube migration following a routine video-assisted thoracoscopic surgery sympathectomy, which was successfully managed with silicone Y-stent insertion. Procedure was done while she was undergoing ECMO; hence, no ventilator connection to the side port of the rigid scope was required. This was our first experience in performing Y-stent insertion fully under ECMO, and the patient had a successful recovery.
