PUERPERIUM6 to 8 weeks following delivery of the placenta in which the uterus returns to its normal state.
Following delivery of the placenta, the uterus rapidly contracts to half of its predelivery size.
The involution that then occurs over the next several weeks is most rapid in nursing women.
Puerperal complications include:Postpartum hemorrhagePostpartum infectionPostpartum depression

PUERPERAL INFECTION:a general term used to describe any bacterial infection of the genital tract after delivery
PAST: constitutes the LETHAL TRIAD of maternal death, along with preeclampsia and obstetrical hemorrhage
PRESENT: maternal deaths from infection have become uncommon due to effective antimicrobials (13% of maternal deaths)
Consist of : Puerpural fever Uterine Infection

PUERPERAL FEVER Puerperal fever, also known as postpartum fever or
puerperal infection
Definition: temperatures in the postpartum fever reach 100.4F(38.0C) or higher. The fevers occur on any two of the first 10 days postpartum, exclusive of the first 24 hours.
Abortion or miscarriage isn’t usually associated with this infection and fever.

Causes : endometritis (most common) urinary tract infection pneumonia\atelectasis wound infection septic pelvic thrombophlebitis.
Septic risk factors for each etiologic condition are listed in order of the postpartum day(PPD) on which the condition generally occurs.

Prolonged and premature rupture of the membranes
Prolonged (more than 24 hours) labor
Frequent or unsanitary vaginal examinations or unsanitary delivery
Retained products of conception
Hemorrhage Maternal conditions, such
as anemia, poor nutrition during pregnancy.
Cesarean birth (20-fold increase in risk for puerperal infection).
Cenital or urinary tract infection prior to delivery.

Diagnose :Physical examination & Laboratory A pelvic examination is done and samples are taken from the genital
tract to identify the bacteria involved in the infection. The pelvic examination can reveal the extent of infection and possibly
the cause. Blood samples may also be taken for blood counts , CRP, or blood
culture. A urinalysis may also be ordered, especially if the symptoms are
indicative of a urinary tract infection. Chest x-ray Wound culture

TREATMENT Treatment of puerperal infection usually begins with I.V.
infusion of broadspectrum antibiotics and is continued for 48 hours after fever is resolved.
Supportive care Symptomatic treatment Surgery may be necessary to remove any remaining
products of conception or to drain local lesions In the presence of thrombophlebitis, heparin therapy
will be needed to provide anticoagulation.

ENDOMETRITIS Ascending polymicrobial infection
Usually normal vaginal flora or enteric bacteria
Primary cause of postpartum infection 1-3% vaginal births 5-15% scheduled C-sections 30-35% C-section after extended period of labor
May receive prophylactic antibiotics <2% develop life-threatening complications
![Page 13: Puerperal Fever Done](https://reader034.vdocuments.net/reader034/viewer/2022042511/577cc3b51a28aba71196ef22/html5/thumbnails/13.jpg)
ETIOLOGY Endometritis is an ascending polymicrobial
infection
The most common organisms are divided into 4 groups: aerobic gram-negative bacilli anaerobic gram-negative bacilli aerobic streptococci anaerobic gram-positive cocci.
Specifically, Escherichia coli, Klebsiella pneumoniae, and Proteus species are the most frequently identified organisms.
![Page 14: Puerperal Fever Done](https://reader034.vdocuments.net/reader034/viewer/2022042511/577cc3b51a28aba71196ef22/html5/thumbnails/14.jpg)
The infection is variously known as endometritis; endoparametritis; or simply, metritis.
Endometritis complicates 1-3% of all vaginal deliveries and 5-15% of scheduled cesarean deliveries.
The incidence of endometritis in patients who undergo cesarean delivery after an extended period of labor is 30-35% and falls to 15-20% if the patient receives prophylactic antibiotics.

TREATMENT: Perineal infections
Treatment of perineal infections includes symptomatic relief with NSAIDs, local anesthetic spray, and sitz baths. Identified abscesses must be drained, and broad-spectrum antibiotics may be initiated.
![Page 30: Puerperal Fever Done](https://reader034.vdocuments.net/reader034/viewer/2022042511/577cc3b51a28aba71196ef22/html5/thumbnails/30.jpg)
TREATMENT: Abdominal wound infections These infections are treated with drainage and inspection of the
fascia to ensure that it is intact. Antibiotics may be used if the patient is afebrile. Most patients respond quickly to the antibiotic once the wound is
drained. Patients do not require long-term antibiotics unless cellulitis has
developed. Studies have shown that closed suction drainage or suturing of the
subcutaneous fat decreases the incidence of wound infection when the subcutaneous tissue is greater than 2 cm in depth
![Page 31: Puerperal Fever Done](https://reader034.vdocuments.net/reader034/viewer/2022042511/577cc3b51a28aba71196ef22/html5/thumbnails/31.jpg)
In emergency cesarean deliveries, use of prophylactic cefazolin has been shown to reduce the rate of postpartum endometritis and wound infection.
Other studies have demonstrated that ampicillin/sulbactam, cefazolin, and cefotetan are all acceptable choices for single-dose antibiotic prophylaxis
Controversy still exists with regard to the need for prophylactic antibiotics during elective deliveries

SEPTIC PELVIC TROMBOPHLEBITIS
Septic pelvic thrombophlebitis is defined as venous inflammation with thrombus formation in association with fevers unresponsive to antibiotic therapy.
