History of Present Illness • Few hours PTA • (+) labor pains • described as irregular contractions, occurring every 10-15 minutes, with a pain scale of 6/10, radiating to the pelvis and back. • No associated symptoms such as vomiting, fever and blurring of vision were noted. Persistence of symptoms prompted consult at QMMC OB-ER hence admitted

  16. Physical Examination • Abdomen • Globular • FH: 32 cms • FHT: 140 • Pelvic Examination • IE: cervix- 2 cms dilated, 50% effaced, Cephalic in presentation, Station (-) 3, (+) BOW, floating

  17. Admitting Diagnosis: G1P0 (0000) Pregnancy uterine 39 weeks 2 days AOG by LMP, CIL

  18. Principal Diagnosis: G1P1 (1001) PUFT Cephalic Arrest in Cervical Dilatation 20 to CPD, delivered via LTCS I to a live Boy AS 9.

  19. Course in the Wards • Partograph

  20. Discussion • Dystocia • Difficult labor • Characterized by abnormally slow progress of labor • Most common indication for primary CS

  21. 4 Major Abnormalities • 1. Abnormalities of the expulsive forces • 2. Abnormalities of the maternal bony pelvis • 3. Abnormalities of the presentation, position or development of the fetus • 4.Abnormalities of soft tissues of the reproductive tract that form an obstacle to fetal descent

  22. American College of Obstetricians and Gynecologists • 1. Abnormalities of the Powers (uterine contractility and maternal expulsive effort) • 2. Abnormalities involving the Passenger (the fetus). • 3. Abnormalities of the Passage (the pelvis).

  23. ABNORMALITIES OF EXPULSIVE FORCES • UTERINE DYSFUNCTION • ABNORMAL LABOR PATTERNS • RUPTURE OF MEMBRANES W/O LABOR • PRECIPITOUS LABOR AND DELIVERY

  24. UTERINE DYSFUNCTION • Failure of cervix to dilate or presenting part to descend • Characterized by lack of progress in any phase of cervical dilatation

  25. FRIEDMAN’S CURVE

  26. Active Phase Labor • At least 4 cm dilated • Regular, frequent, usually painful contractions • Dilate at least 1.2-1.5 cm/hr • Are not comfortable with talking or laughing during their contractions

  27. CAUSES OF PROLONGED LATENT PHASE

  28. CAUSES OF ARREST DISORDERS

  29. Fetopelvic Disproportion • Diminished pelvic capacity • Excessive fetal size

  30. Fetopelvic Disproportion • Diminished pelvic capacity • Any contraction of the pelvic diameters that diminishes the capacity of the pelvis that can create dystocia during labor • a. Contracted pelvic inlet • b. Contracted midpelvis • c. Contracted pelvic outlet • d. Pelvic fractures and rare contractures

  31. Diagnosis of Diminished Pelvic Capacity • a. Xray Pelvimetry • b. Computer Tomographic Scanning • c. Magnetic Resonance Imaging

  32. Fetopelvic Disproportion • Excessive fetal size • Fetal size alone is a seldom explanation for failed labor

  33. Maternal Effects of Dystocia • a. Intrapartum Infection • After the membrane ruptured, bacteria can enter the amnionic fluid, traverse the amnion and invade the decidua and chorionic vessels thus causing maternal and fetal bacteremia and sepsis. • Infection may complicate prolonged labor and pose a serious danger both to mother and fetus. • b. Uterine Rupture • Abnormal thinning of the lower uterine segment that can create a serious danger during pronged labor.

  34. c. Pathological Retraction Ring

  35. d. Fistula Formation • e. Pelvic Floor Injury • f. Postpartum Lower Extremity Nerve Injury

  36. Fetal Effects of Dystocia • a. Caput Succedaneum • b. Fetal Head Molding • Factors associated with molding: • 1. Nulliparity • 2. Oxytocin labor stimulation • 3. Delivery with a vacuum extractor

  37. THANK YOU!
