Post partumpneumomediastinum (Hamman syndrome): a case report.
J Pak Med Assoc Jan ;68(7):1108-9.

Excessive pushing and valsalva during labour is associated with subcutaneous emphysema and pneumomediastinum during labour and post partum. Although rare but is a potentially serious complication that must be identified and managed appropriately to avoid its rare consequence called malignant pneumomediastinum, requiring surgical intervention. A 30 year old, primigravida, presented to a tertiary care hospital with complaints of shortness of breath of 4 days duration after a normal vaginal delivery. CT chest showed bilateral consolidation and pneumomediastinum. She was managed conservatively with supportive measures and was clinically stable before being discharged on request to a nearby health facility. On follow up complete resolution of pneumomediastinum was reported. Recognition of post partum pneumomediastinum, its presentation and associated complications need to be acknowledged in a teriary care hospital, with proper management. Although the condition is rare, but in subsequent pregnancies physicians need to be cautious, and instrumental delivery or caesarean section may be considered to avoid excessive valsalva. No definite evidence of recurrence has been proven.
