Make sure you take correct references from books like William Gynecology and Obstetrics, DC dutta etc. Please give me correct diagnosis with all the correct ways. Do not give a generalize diagnosis

CASE № 46 Multigravida, 25 years old, admitted in the hospital with the prolapse of umbilical cord. Rupture of amniotic sac occur when patient was on the way to the hospital, contractions begun 5 hours ago. The third pregnancy proceeded without complication to full term. The first pregnancy 3 years ago was finished by normal urgent sorts, the child was healthy, second pregnancy - spontaneous abortion on the second month of pregnancy one year ago. The size of a pelvis: 26- 29-33-20. Longitudinal lie of fetus, left lateral position, breech presentation. Estimated weight of fetus - 3100,0±200,0. Auscultation of the fetal heart beat: 100 beats/minute, rhythmical. Vaginal examination: cervical dilatation full, without amniotic sac, in vagina can feel prolapsed pulsation of umbilical cord. Buttocks in the narrow part of pelvic cavity. 1. The Diagnosis. 2. The Plan of management. 3. What mistakes did the doctor do? Based on the obstetric knowledge algorithm (umbilical cord prolapse, breech presentation, full dilation), here is the structured analysis. --- 1. Diagnosis G.P.A.M: · Gravidity: 3 (third pregnancy) · Parity: 1 (first pregnancy – normal urgent delivery) · Abortus: 1 (spontaneous abortion at 2 months) · Living children: 1 Pregnancy - Trimester: 3rd trimester (full term) In labor - stages: · Duration of contractions: 5 hours · Cervical dilatation: Full (10 cm) – second stage of labor · Membranes: Ruptured (on the way to hospital) Fetal lie, presentation, position, abnormalities: · Lie: Longitudinal · Position: Left lateral position · Presentation: Breech · Abnormalities: Umbilical cord prolapse (felt in vagina, pulsating) Complications of maternal and fetal: · Fetal: FHR 100 bpm (normal 110–160) → bradycardia due to cord compression · Maternal: None mentioned; pelvis size: 26-29-33-20 → normal pelvis (distances in cm: interspinous 26, intercristal 29, external conjugate 33, Baudelocque 20) Estimated fetal weight: 3100 g ± 200 g (appropriate for term) Primary diagnosis: Umbilical cord prolapse in the second stage of labor (full cervical dilatation) with breech presentation, complicated by acute fetal distress (bradycardia 100 bpm). Background: Multigravida G3P1A1, term pregnancy, normal pelvis. --- 2. Plan of management This is an obstetric emergency – immediate action required. A. Immediate maneuvers to relieve cord compression: 1. Manual elevation of presenting part (breech) – insert hand into vagina and lift the breech off the cord 2. Position change – Trendelenburg (head down) or knee-chest position to reduce gravity pressure on cord 3. Oxygen to mother – 8–10 L/min via face mask B. Immediate delivery – choice depends on conditions: At full cervical dilatation with breech in the narrow part of pelvic cavity: Option Indication Action Immediate vaginal breech delivery Fetal bradycardia, full dilation, breech low in pelvis, experienced operator Emergency breech extraction – grasp feet, deliver buttocks, body, arms, then head (Mauriceau–Smellie–Veit maneuver or forceps to aftercoming head) Emergency cesarean section If breech not low enough for immediate extraction, or no experience with vaginal breech Immediate C-section – move patient to OR within minutes. But with cord prolapse and bradycardia, every minute counts. Decision in this case: · Full dilation + breech in narrow part of pelvic cavity → immediate vaginal breech extraction is possible and faster than C-section. · Recommendation: Proceed with emergency breech extraction immediately in the delivery room. C. Supportive measures during delivery: · Continue manual elevation of cord until delivery of head · Administer atropine 0.5 mg IV to mother if severe bradycardia (some protocols) · Prepare neonatal resuscitation team (risk of birth asphyxia) D. Post-delivery: · Active management of third stage (oxytocin 10 IU IM) · Examine cord for thrombosis or compression injury · Apgar scoring at 1 and 5 minutes · Neonatal intensive care if needed --- 3. What mistakes did the doctor do? Possible mistakes before and during admission: Mistake Explanation 1. Failure to diagnose breech presentation antenatally Breech at term should be identified by ultrasound at 36 weeks. ECV or planned C-section could have prevented this emergency. 2. No delivery plan for breech A known term breech without planned C-section is a major error. 3. Artificial rupture of membranes (ARM) with high presenting part If membranes ruptured artificially with breech not engaged → cord prolapse risk high. Here rupture occurred "on the way" – possibly spontaneous, but if doctor performed ARM, that was a mistake. 4. Allowing patient to travel to hospital in labor with breech Patient should have been admitted earlier, or ambulance with ability for emergency delivery should have been arranged. 5. Delayed diagnosis of cord prolapse FHR 100 bpm at auscultation is a late sign. Continuous CTG would have detected earlier decelerations. 6. No immediate action upon arrival Upon diagnosis of cord prolapse with bradycardia, delivery must be within minutes. Any delay (waiting for OR, anesthesia) is a mistake. 7. Attempting vaginal breech delivery without expertise If the attending doctor is not skilled in breech extraction, attempting it is dangerous; C-section would be safer even with cord prolapse. 8. No fetal monitoring during transport Patient in labor with breech should have had continuous monitoring. 9. No preparedness for neonatal resuscitation Breech + cord prolapse + bradycardia → high risk of depressed newborn. Lack of neonatologist/resuscitation equipment is a mistake. --- Final answer summary: Question Answer 1. Diagnosis Umbilical cord prolapse, second stage of labor (full dilation), breech presentation, acute fetal distress (FHR 100 bpm), term pregnancy, G3P1A1 2. Plan of management Manual elevation of breech off cord, Trendelenburg position, O₂ to mother, immediate vaginal breech extraction (since full dilation + breech low), neonatal resuscitation standby 3. Mistakes Failure to diagnose breech antenatally; no planned C-section; possible ARM with high presenting part; delayed diagnosis of cord prolapse; no continuous CTG; delay in action; possible lack of expertise for breech extraction; inadequate transport monitoring
