Dysfunctional Labour & Partograph

  1. 1. Dysfunctional Labour and Partograph SALSO TEAM HOSPITAL UMUM SARAWAK
  2. 2. Correct diagnosis of labour• Regular contractions• Interval gradually shortens• Intensity of pain gradually increase• Duration of contraction increase• Progressive cervical effacement and dilatation• “Show’ may be present• (Progress of labour not stopped by sedation)• (Tightening not = contractions)
  3. 3. Importance:• Proper monitoring• Prevent unnecessary intervention - Artificial rupture of membranes - Wrong diagnosis of prolonged latent phase - Admission
  4. 4. “False” labour• Uterine contractions impalpable/ infrequent• Misdiagnosis unnessesary induction/ augmentation  higher risk of failure with an increased risk of Caesarean section & chrioamnionitis
  5. 5. Definition• 1st Stage: – Start of labour  Full dilatation of cervix• 2nd Stage: – Full dilatation  delivery of baby• 3rd Stage: – Birth of baby  delivery of placenta
  6. 6. Points to observe for…• Latent phase: Considered prolonged if it is greater than 8h in nullipara and 6h in multipara.• Active phase: On or at the left of an alert line• 2nd Stage: Need assessment if expulsive phase more than 30 minutes. (Max 1 hour for primips & ½ hour for multips) – Total 2 hours for nullips & 1 hour for multips• 3rd Stage : Retained placenta if not delivered by 30 minutes
  7. 7. Labour: Principles of management1. Initial assessment2. Diagnosis and intervention of abnormal labour3. Close monitoring of fetal and maternal condition4. Adequate pain relief5. Adequate hydration6. Emotional support/ supportive companion
  8. 8. Initial assessment• Define risk – Current & previous pregnancy – Medical/ surgical problems – Fetal condition• Degree of monitoring needed• Level of staff to manage the patient
  9. 9. Partograph• Diagrammatic representation of the progress of labour• “Story of a patient in labour”• Main components: • Progress of labour • Maternal condition • Fetal condition • Drugs given
  10. 10. PartographPatient came in latent phase normal progress
  11. 11. PartographPatient came in latent phase  normal progress ( Showing station )
  12. 12. PartographPatient came in active phase of labour  normal/ goodprogress
  13. 13. PartographPatient came in latent phase  normal/good progress
  14. 14. Abnormal partograph (poor progress)• Latent phase > 8 hours• Cervical dilatation to the right of alert line• Cervical dilatation at or beyond action line
  15. 15. Partograph Dilatation < 4 cm despite 8 hours of regular contractionPatient with prolonged latent phase
  16. 16. Partograph Dilatation < 1cm/ hour in active phase due to ineffective uterine contractions < 3:10 < 40secPatient came in active phase  Primary dysfunctional labour
  17. 17. PartographPatient came in active phase  Secondary arrest
  18. 18. Secondary Arrest• Arrest of cervical dilatation and descent of presenting part despite good uterine contractions. Absolute CPD Relative CPDBig fetus /& small pelvis Fetal malposition
  19. 19. PartographIntensity and frequency of contractions (Mild) (Moderate) (Severe)
  20. 20. Evidence of obstructed labour • Secondary arrest • Large caput • 3rd degree moulding • Poorly applied cervix to presenting part • Odematous cervix • Maternal/ fetal distress
  22. 22. Factors affecting labour: 3 P’s- Power- Passage- Passenger - Position - Size - Attitude ( posture of fetus) ie. flexion/ deflexion/ extension
  23. 23. Power• Adequate effective contractions are needed for adequate progress of labour• Usually 3-4 in 10 min• Usually 40-60 s duration
  24. 24. Augmentation ( oxcytocin)• Correct dose and titration• To achieve “efficient “/”adequate” contraction.• Observe for hyperstimulation• Careful consideration in multipara and patients with previous scar• Max pitocin licensed for20 mu/min – Titrate 1, 2, 4,8, 12, 16,20, 24, 28, 32 ml/hr
  25. 25. Hyperstimulation• Prolonged contractions (> 2 mins)• Frequent contractions (<1:2)• Tetanic contractions (continuous) Intervention needed if associated with CTG changes
  26. 26. Passage• Clinical and X-ray pelvimetry – not used in modern obstetrics• Adequacy of pelvis can only be ascertain through labour and delivery• Passage may be adequate but might not be for a big baby
  27. 27. Passenger• Size of baby• Congenital abnormalities e.g. hydrocephalus, Anencephaly• Malposition : Incorrect positioning of the vertex (OP/ Deflexed head)• Malpresentation: Presence of presenting part other than vertex ( face, brow, breech, shoulder, compound)
  28. 28. FHR monitoring• In latent phase: * Low risk : Hourly * High risk : Every 15-30 min•• In active phase * Low risk: Every 30 min *High risk: Every 15 min
  29. 29. FHR monitoring• During second stage: * Low risk : Every 15 min *High risk: Every 5 min or after each contraction/pushing
  30. 30. FHR monitoring• Suspicious trace requires intervention or a referral to a senior person• Repeating trace with the hope it will return to normal is not advisable
  31. 31. FHR monitoring• In a patient in labour (contracting), fetal heart rate must be documented especially after a contraction.• Documentation of “fetal heart heard” is inadequate More on CTG in tomorrow’s lecture …
  32. 32. Adequate analgesia• Reduce pain perception & stress• “Tarik nafas” is not an analgesia at all• IM Pethidine 1-2mg/kg + Phenergan 0.5mg/kg 6 hourly• Entonox inhalation (50% O2 and 50% Nitrous oxide) at the start of contraction• Continuous epidural analgesia
  33. 33. Adequate hydration• Good hydration is important for satisfactory labour progress• Review hydration status regularly• Urine volume and urine ketones assessed• Allow low residual diet / oral fluids in labour except for high risk cases
  34. 34. Companionship / Doula• Provides reassurance to patient• Shown to: – Reduce analgesia requirements – Reduce Caesarean section & instrumental – Improve vaginal delivery rates

  36. 36. Moulding Grade 0(No moulding), 1(suturesopposed),2(overlap;reducible), 3 (overlap; not reducible)
  37. 37. Caput succedaneum• (“Substitute head”)• Normal occurance due to pressure of cervix interrupting venous & lymphatic scalp drainage during labour.• Serous effusion between aponeurosis and periosteum• Disappear after few hours of birth
