Benign fever following vaginal delivery

Area of Science:

• Obstetrics and Gynecology
• Postpartum Care
• Infectious Disease Diagnosis

Background:

• Differentiating benign postpartum fever from endometritis is crucial for appropriate patient management.
• Understanding risk factors for benign postpartum fever can improve clinical decision-making.

Purpose of the Study:

• To identify characteristics and risk factors associated with benign single-day postpartum fever.
• To aid in distinguishing benign fevers from more serious postpartum infections like endometritis.

Main Methods:

• Retrospective cohort study of 2137 vaginal deliveries.
• Analysis of patient data using odds ratios and multiple logistic regression.
• Random selection from a larger cohort of deliveries between 1979 and 1992.

Main Results:

• Benign single-day fever occurred in 3.3% of patients; endometritis in 1.6%.
• Primiparity (OR, 3.4) and uterine pressure catheter use (OR, 2.4) were independently associated with single-day fever.
• Single-day fevers began earlier (4.0 hrs vs 30.2 hrs) and were lower grade (38.2°C vs 38.9°C) compared to endometritis.

Conclusions:

• Primiparous women and those monitored with a uterine pressure catheter are more prone to benign single-day fevers.
• Benign single-day fevers typically present as early, low-grade temperature elevations.
• Endometritis is characterized by later onset and higher postpartum fevers.
