Slide 1-

MATERNAL PHYSIOLOGY PATRICK DUFF, M.D. UNIVERSITY OF FLORIDA
Slide 2-

Placenta Hormone production Mechanisms of placental transfer Changes in uterus Cardiopulmonary changes Hematologic changes Alterations in GI function Renal function changes MATERNAL PHYSIOLOGY OVERVIEW
Slide 3-

PLACENTAL HORMONE PRODUCTION
Slide 4-

HORMONE PRODUCTION BY THE PLACENTA
Slide 5-

MECHANISMS OF PLACENTAL TRANSFER
Slide 6-

CHANGES IN UTERUS Uterine blood flow increases significantly Uterine blood flow may approach 500 – 750 cc/ minute Hemorrhage is key cause of maternal death
Slide 7-

DISTRIBUTION OF UTERINE BLOOD FLOW DURING PREGNANCY
Slide 8-

CARDIOVASCULAR CHANGES DURING PREGNANCY
Slide 9-

CHANGES IN CARDIAC OUTPUT DURING LABOR
Slide 10-

DANGEROUS CARDIAC DISEASES IN PREGNANCY Stenotic valve lesions Ischemic heart disease Marfan syndrome Eisenmenger’s syndrome Primary pulmonary hypertension
Slide 11-

PULMONARY FUNCTION ALTERATIONS IN PREGNANCY
Slide 12-

PULMONARY FUNCTON ALTERATIONS IN PREGNANCY
Slide 13-

PULMONARY FUNCTION ALTERATIONS IN PREGNANCY
Slide 14-

ALTERATIONS IN ARTERIAL BLOOD GASES Increased pH Decreased pCO2 Decreased HCO3 PARTIALLY COMPENSATED RESPIRATORY ALKALOSIS
Slide 15-

HEMATOLOGIC ALTERATIONS IN PREGNANCY
Slide 16-

PRINCIPAL CAUSES OF ANEMIA IN PREGNANCY
Slide 17-

PERIPHERAL BLOOD SMEARS
Slide 18-

HEMATOLOGIC ALTERATIONS IN PREGNANCY * Most common causes of thrombocytopenia – pre-eclampsia and gestational thrombocytopenia
Slide 19-

Enhanced hepatic synthesis of I, II, VII, VIII, IX, and X Placenta  III (tissue thromboplastin) Platelets  aggregate more readily COAGULATION CHANGES IN PREGNANCY
Slide 20-

VIRCHOW’S TRIAD THROMBOSIS Venous stasis Alteration in venous wall Hyper-coagulable state
Slide 21-

GASTROINTESTINAL ALTERATIONS IN PREGNANCY
Slide 22-

CHANGE IN ANATOMIC LOCATION OF APPENDIX IN PREGNANCY
Slide 23-

GASTROINTESTINAL ALTERATIONS IN PREGNANCY
Slide 24-

Renal blood flow increases 30 – 40 % above pre-pregnancy levels GFR ( creatinine clearance) increases Serum BUN, creatinine, and uric acid decrease RENAL FUNCTION ALTERATIONS IN PREGNANCY
Slide 25-

FREQUENCY OF UTIs IN PREGNANCY
Slide 26-

MICROBIOLOGY OF UTIs IN PREGNANCY
Slide 27-

INCREASED RISK OF PYELONEPHRITIS IN PREGNANCY Progesterone inhibits ureteral peristalsis Mechanical compression of ureter by gravid uterus Complications of pyelonephritis Preterm labor Sepsis and ARDS
Slide 28-

INCREASED RISK OF NEPHROLITHIASIS Increased concentration of calcium in the urine Urinary stasis Most common stones Calcium oxalate Struvite
