Puerperal pyrexia is defined as temperature ≥38°C occurring after the first 24 hours of delivery. Which is the MOST common cause of puerperal pyrexia in the first 24–48 hours?
- A Endometritis from ascending genital tract infection ✓
- B Breast engorgement ('milk fever')
- C Urinary tract infection
- D Deep vein thrombosis
Correct answer: A. Endometritis from ascending genital tract infection
Explanation
Endometritis is the most common cause of puerperal pyrexia, occurring particularly in the first 24–48 hours after caesarean section or complicated vaginal delivery, caused by ascending polymicrobial infection (group B Streptococcus, E. coli, anaerobes). 'Milk fever' (breast engorgement) characteristically occurs on day 3–4 and is now recognised as a physiological phenomenon not a true infection. UTI typically presents a few days later. DVT usually causes lower-grade fever and presents later in the puerperium.
