Which of the following steps has proven benefit in decreasing puerperal infection following cesarean section:
**Core Concept**
Proper uterine incision closure and minimizing post-operative complications are critical in reducing puerperal infections following cesarean sections. Effective hemostasis and minimizing the risk of endometritis are essential in this context.
**Why the Correct Answer is Right**
The correct answer is prophylactic antibiotics. The administration of prophylactic antibiotics has been shown to decrease the incidence of puerperal infections, including endometritis, following cesarean sections. This is achieved by reducing the bacterial load in the uterus and preventing the onset of infection. The choice of antibiotic is crucial, and a single dose of a broad-spectrum antibiotic, such as cefazolin or ceftriaxone, is commonly administered at the time of surgery.
**Why Each Wrong Option is Incorrect**
**Option A:** Prophylactic antibiotics are not administered in the form of heparin. Heparin is an anticoagulant used to prevent thrombosis, not infection.
**Option B:** Prophylactic antibiotics are not administered in the form of oxytocin. Oxytocin is a uterotonic agent used to induce or augment uterine contractions, not to prevent infection.
**Option C:** Prophylactic antibiotics are not administered in the form of a uterine massage. Uterine massage may be used to help reduce post-cesarean bleeding, but it does not have a proven benefit in decreasing puerperal infections.
**Clinical Pearl / High-Yield Fact**
Prophylactic antibiotics should be administered within one hour of skin incision and at least 30 minutes before the delivery of the baby.
**Correct Answer:** D. Prophylactic antibiotics.
