Antimicrobial prophylaxis for cesarean delivery before skin incision

Area of Science:

• Obstetrics and Gynecology
• Infectious Disease Prevention
• Surgical Prophylaxis

Background:

• Antimicrobial prophylaxis is standard for cesarean deliveries.
• The optimal timing for antimicrobial administration remains a key consideration for preventing maternal infections.

Purpose of the Study:

• To evaluate the impact of a hospital-wide policy change on the timing of antimicrobial prophylaxis administration in cesarean deliveries.
• To assess the effect of pre-incision versus post-cord clamping antibiotic timing on maternal and neonatal infectious complications.

Main Methods:

• A retrospective review of cesarean deliveries was conducted, comparing two groups based on antibiotic prophylaxis timing.
• Group 1 received antibiotics after umbilical-cord clamping (July 2002-November 2004).
• Group 2 received antibiotics before skin incision (June 2005-August 2007).

Main Results:

• A significant reduction in postpartum endometritis (2.2% vs. 3.9%) and wound infection (2.5% vs. 3.6%) was observed in the group receiving prophylaxis before skin incision.
• Multivariable analysis confirmed that pre-incision prophylaxis was associated with lower rates of endometritis (OR 0.61) and wound infection (OR 0.70).
• No adverse effects on neonatal infection rates were identified.

Conclusions:

• Administering antimicrobial prophylaxis before skin incision for cesarean delivery is associated with decreased maternal infectious complications.
• The timing of prophylaxis before skin incision does not negatively impact neonatal outcomes.
• Current findings support the implementation of pre-skin incision antimicrobial prophylaxis as a standard practice in cesarean deliveries.
