Wheezing Tachycardia Watch for signs of DIC & seizures. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 PRINCIPLES OF MANAGEMENT: Control of blood pressure Prevent convulsions using MgSo4 as per guidelines. Treat eclampsia (as per protocol.) Restore plasma volume and maintain urine output Perform baseline investigations and monitor progress Prevent complications Plan management of the pregnancy Consider use of Dexamethasone in preterm if not contraindicated even in severe cases. Plan postpartum management National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 Control of blood pressure Slowly reduce blood pressure to safe levels (MAP<125mmHg, Diastolic BP<105mmHg), Avoid hypotension. Aim to keep MAP between 115-125 mmHg (Diastolic BP between 90- 105 mmHg) confirm the BP reading with Mercury Sphygmomanometer. when “Dinamap” (automatic BP reading machine) is used to record patient’s blood pressure. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 Prevent convulsions using MgSo4 Anticonvulsants are indicated : • if there is severe hypertension which cannot be controlled by antihypertensives • and also proteinuria 3+ or 4+ • and hyper-reflexia (indicated by the presence of ankle clonus 2 or more beats) National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 Treatment eclampsia : Principles If a patent presents with eclampsia, initial management should aim at • control of convulsions • maintaining the airway • and preventing trauma to the patient (see protocol.) National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 Restore plasma volume and maintain urine output Expansion of the plasma volume prior to antihypertensive therapy minimizes the risk of hypotension and may improve the hypertension per se. Hypovolaemia is an important feature of pre-eclampsia caused by the loss of plasma proteins into the interstitial space and the urine. This is a Consultant decision National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 Plan management of the pregnancy timing of delivery hospital equipped with SCBU (Special care baby unit) National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 MANAGEMENT GUIDELINES DURING DELIVERY Timing of delivery deliver most patients with pre-eclampsia once the situation is under control. Fetal Assessment assess fetal well-being by CTG and ultrasound scan. Mode of delivery IUGR and fetal hypoxia are common and so a caesarean section is the most appropriate form of delivery. Induction Induction of labour should be in labour ward (with continuous monitoring). Epidural anaesthesia If an epidural is used together with antihypertensive agents, hypotension may ensue, so measure BP at least every 15 mins. And preload the patient with 500 mls N saline IV. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 MANAGEMENT GUIDELINES DURING DELIVERY 2nd Stage of Labor Ventouse/Forceps delivery can be used if obstetrically indicated Oxytocin and Methergin oxytocin 10 iu i.v. should be given, with delivery of the anterior shoulder. If necessary an i.v. infusion of Oxytocin can be given after delivery. Syntometrine and Methergin are CONTRINDICATED 3rd Stage of labor A physiological third stage is contraindicated Corticoids Consider use of Dexamethasone in preterm if not contraindicated, even in severe cases National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 RECOGNISE & PREVENT THE FOLLOWING COMPLICATIONS Acute renal failure: Coagulopathy Cerebral haemorrhage Cardiovascular complications Hepatic complications Ocular complications National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 RECOGNISE & PREVENT THE FOLLOWING COMPLICATIONS Acute renal failure: Oliguria is common and may be improved by the treatment of hypovolaemia National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 RECOGNISE & PREVENT THE FOLLOWING COMPLICATIONS Coagulopathy Mild coagulation abnormalities, particularly a low platelet count. In severe cases disseminated intravascular coagulation (DIC) occurs with reduced platelet count, elevated prothrombin time, elevated fibrin degradation products, low fibrinogen levels and reduced factor VIII activity. Treatment involves replacement of coagulation factors with fresh frozen plasma, cryoprecipitate and platelets the haematologist’s opinion should be sought early in the case of abnormal clotting studies. Early delivery of the fetus is desirable. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 RECOGNISE & PREVENT THE FOLLOWING COMPLICATIONS Cerebral haemorrhage (Rare complication. ) The risk can be reduced by : prevention of eclampsia, control of hypertension and correction of coagulation abnormalities National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 RECOGNIZE & PREVENT THE FOLLOWING COMPLICATIONS Cardiovascular complications may complicate pre-eclampsia Hypertensive cardiac failure, cardiomyopathy and coronary artery insufficiency . Seek a Cardiologist opinion. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 RECOGNIZE & PREVENT THE FOLLOWING COMPLICATIONS Hepatic complications Pre-eclampsia may be complicated by hepatic enlargement, haemorrhage and even rupture. Liver failure may occur in severe cases and is treated by supportive therapy. This may present as part of the HELLP syndrome haemolysis/hypertension, elevated liver transaminases, low platelet count National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 RECOGNIZE & PREVENT THE FOLLOWING COMPLICATIONS Ocular complications Eclampsia may be preceded by visual disturbance, particularly seeing flashing lights or stars. Retinal haemorrhage or detachment and macular oedema may cause reduced acuity National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 MANAGEMENT of SEVERE PRE-ECLAMPSIA : ASSESSMENT Transfer the patient to labour ward. Initiate an emergency observation chart for each patient Record the vital parameters Investigate Lab tests: (1-4 repeated every 12 hours) Manage labour according to protocol : National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 1. Transfer the patient to labour ward If diastolic BP>110mm Hg, systolic BP>170mm Hg, MAP>125mm Hg on two occasions 5-10 mins apart. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 2. Initiate an emergency observation chart for each patient providing a complete record of the patient’s observations, fluid balance and investigation results as indicated below: Gestational age and size Amount of amniotic fluid Uterine irritability or contractions Fetal condition – clinical and CTG Check FHR every 15 minutes. Other pregnancy complications multiple pregnancy, preterm labour, abruption. Weight of patient National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 3. Record the followings parameters: Blood pressure using dinamap (every 15 mins or every 5 mins if Map>140mmHg). Confirm with the mercury sphygmomanometer.

Pulse rate (every 15 mins). Temperature (4 hourly). Optic fundi (12 hourly). Pulse-oxymetry. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 4. Investigate the following Lab tests 1-4 repeated every 12 h. o Full blood count – haemoglobin (N.B high = haemoconcentration) and platelets. o Coagulation screen (including FDPs if any other abnormality). o Renal function tests – creatinine, urea electrolytes, urate. o Liver function tests and serum protein levels. o Hourly urine collection for protein, if time prior to delivery allow, collect a 24 hour urine for protein and creatinine clearance. MSU for microscopy (evidence of renal disease – granular casts, rule out infection) National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 5. Manage labour as followed Consider expediting. All inductions of labour performed in labour ward (including prostin method). Preload patients with an additional 500 mls N-saline (0.9%) before epidural. Consider ventouse/forceps delivery if indicated. Oxytocin (syntocinone) 10 iu i.v. (NO syntometrine in third stage. ) National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 TREATMENT REGIMENS FOR SEVERE PRE-ECLAMPSIA (see separate leaflet for doses) Initial control of BP: Hydralazine – DO NOT mix with dextrose Labetalol – Not to be used with ASTHMA or CARDIAC PATHOLOGY. Nifedipine (Retard Tablets): (be careful if Mgso4 is used as well.) Maintain BP by: Hydralazine Labetalol Nifedipine (Retard Tablets); be aware that Nifedipine potentiates the action of magnesium sulphate Magnesium Sulfate : its efficacy is well established in treatment. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Severe Pre – Eclampsia 1 ABOUT MAGNESIUM SULFATE (see separate leaflet for regimen and doses) Indications for Magnesium Sulfate: Severe hypertension (MAP> 125 mmHg, Diastolic BP> 110 mmHg) after 1 hour of parenteral therapy and proteinuria 3+ or 4+ plus hyperreflexia with clonus (4 beats or more) or epigastric pain. Contraindications of Magnesium Sulfate: Renal failure or severe oliguria Cardiac disease Bolus dose Must be given through a separate cannula. Initially, administer 20 ml (4g) of magnesium sulphate i.v.as 20% solution over 10 minutes. Alternate method: dilute 4 g MgSO4 in 80 ml of N/S to end up with 100 ml solution and infuse it slowly 10 ml/minute To be administered by resident doctor. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Ante partum Hemorrhage 2 Topic 4, B High Risk Cases Stopped Here Subtopic 2 Management of Ante partum Hemorrhage Standard Statement Obstetric hemorrhage (APH, PPH, Bleeding in early pregnancy) is one of the 3 most common causes of maternal death in the developing countries. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Ante partum Hemorrhage 2 ETIOLOGY Bleeding from the genital tract after 24 weeks gestation may be due to : Placenta previa Placental abruption Local conditions of cervix, vagina, vulva Vasa previa Consider other rare lesions e.g. hemorrhoids Bleeding disorders. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Ante partum Hemorrhage 2 ACTIONS: If moderate or major bleeding Keep NPO till further decision form the consultant or Registrar/Senior resident. First step PLUS the followings, Call for help. Consider taking obstetric emergency trolley bedside. Insert IV Canula G 14 & initiate Hartmann's solution/Ringer lactate. Insert catheter. Measure intake & output Q ½ hour. Observe & measure bleeding closely & consider weighing linens & saving soaked pads for review. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Ante partum Hemorrhage 2 ACTIONS: If Minor ante partum hemorrhage • Obtain a detailed history (precipitating factors and amount of blood Loss), • Perform a general examination • Check gestation. • Check & evaluate the CTG. & ultrasound reports for placental site. • Perform gentle speculum examinations, unless known to have major placenta previa or if no ultrasound report available • Check lab results & give anti D if Rhesus negative. • Transfer to ward if no signs of major bleeding, significant uterine tenderness or fetal distress. If term consider induction of labor after discussing with Consultant. If preterm give dexamethazone (as detailed in PTL protocol) National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Ante partum Hemorrhage 2 Obtain a detailed history (noting precipitating factors and amount of blood Loss), Time of the onset of bleeding & the activities at the time prior to the bleeding. History of previous episode of bleeding Amount of bleeding Any history of pain, trauma, sexual intercourse & uterine contractions. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Ante partum Hemorrhage 2 Perform a general examination especially for signs of uterine tenderness. Check the vital signs Immediately.

Inform • Anesthetist • Neonatal unit 4. Discuss with consultant 5. If clotting studies are abnormal discuss with hematologisit 6. Give • ranitidine 50 mg in 20 mls saline slowly (over 2 mins) IV (unless already given orally) • and metoclopramide 10mg (over 2 mins) IV. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Ante partum Hemorrhage 2 Specific rules • Delivery should be effected. If no evidence of placenta previa, the cervix is favorable and there is no fetal distress, induction of labor may be appropriate, labour often progresses rapidly in the event of APH due to placental abruption. • There should be early recourse to caesarean section if blood loss increases or if there are subtle signs of maternal shock e.g. increasing tachycardia or fetal distress. Fit young woman maintain their blood pressure despite extensive bleeding • In all other circumstances proceed immediately to caesarean section. • The patient should be closely monitored in the labor ward until her condition is satisfactory. Observations continued in ICU observation chart. DO NOT give diclofenac (Voltarol) : Risk of bleeding & renal shut down. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Ante partum Hemorrhage 2 If Major ante partum HH (blood loss in excess of 1000 mls) or abruption resulting in fetal death, add the following steps Always inform consultant Collect obstetric emergency trolley. Cross match at least 6 units of blood. Give Oxygen Blood transfusion as soon as possible Deliver by caesarean section immediately if the fetus is still alive. In the event of fetal death, mode of delivery is to be decided by Consultant. Decision for a vaginal delivery will be considered with an overall view of the patient’s clinical scenario. Clotting studies should be repeated every 4 hours for the first 12 hours. After delivery, maintain an Oxytocin infusion in Hartmann’s solution National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Ante partum Hemorrhage 2 Blood transfusion as soon as possible 1. If life threatening bleeding, other relevant blood groups. (i.e. Rh O –ve blood) are given with out cross matching. 2. If the patient is showing signs of coagulation defects, further steps are taken to obtain blood products i.e. • • • Fresh Frozen Plasma Platelets Cryoprecipitate 3. CVP line is to be considered ( inserted by the anesthetist) 4. If there has been an abruption extensive enough to result in fetal death the patient will always require at least 4 units of blood whatever the initial hemoglobin level and this should be given as soon as the cross match is completed National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Ante partum Hemorrhage 2 In the event of fetal death, the mode of delivery is to be decided by the Consultant. 1. Induction of labor with very careful observation of maternal condition may be appropriate if the maternal condition is stable and if labor progresses rapidly. 2. Even if the fetus is dead, immediate caesarean section may well be preferable UNLESS the cervix is found to be at least 4 cms dilated in which case it may be reasonable to perform an ARM and augment labour with oxytocin. 3. A caesarean section may still be necessary unless progress of labor is rapid.

Definition PROM premature rupture of membranes is membrane rupture occurring before the ondet of labour, irrespective of gestation National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions pre-labor rupture membranes 3 Management : Specific Actions 1. Admit the woman and follow the routine admission procedures. 2. Conduct a detailed history with particular focus on dates. 3. Perform a complete physical exam and search for contractions. 4. Confirm membranes status by performing a sterile speculum exam, 5. Conduct the following investigations: 1. Complete blood count 2. Intracervical and HVS for culture and sensitivity 3. MSU for culture and sensitivity 4. Ultrasound assessment of fetal status if labour is not advanced. 5. CTG if pregnancy reached 28 weeks. 6. If labour is inevitable: Inform neonatal unit and check cot state. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions pre-labor rupture membranes 3 Management of PROM according to Gestational age Gestation between 26-33 weeks + 6 j If not associated with uterine contractions, conservative management If contractions, to suppress labour is an Consultant’s decision Conservative management TOCOLYSIS If uterine contractions, suppress labour after excluding contra indications. STEROIDS : Steroids enhance fetal lung maturity: 2 doses of 12mg betamethazone/dexamethasone IM 12 h apart in the first 24 hours Repeat the course only once if PROM occurred before 29 weeks. ANTIBIOTICS: Give a single course of erythromycin 500 mg 6 hourly for 5 days. Alternatively Augmentin 375 mg 8 hourly for 7 days. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions pre-labor rupture membranes 3 Contra indications to tocolyse 1. Fetal death 2. Fetal distress 3. Fetal abnormality incompatible with survival 4. Chorioamnionitis 5. Antepartum haemorrhage 6. Medical conitions: Cardiac disease and Hyperthyroidism 7. Obstetric indication for delivery e.g. severe pereclampsia etc. 8. Advanced labour i.e. cervical dilatation of 4cm or more National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions pre-labor rupture membranes 3 Management of PROM according to Gestational age Gestation between 26-33 weeks + 6 j : Conservative M. : Follow-UP • Daily palpation for tender uterus, assessment of liquor color & CTG. • Check white cell count + CRP twice/week. • Weekly Scan for estimated fetal weight and biophysical profile If there is any evidence of infection, hemorrhage or fetal distress then labor should be induced or rarely a caesarean section may be appropriate (Consultants must be aware of such cases). In the case of suspected sepsis antibiotics should be commenced immediately. If the results of an HVS suggest a specific organism appropriate antibiotics Otherwise commence cefuroxime 1.5g loading dose then 750 mg 8 hourly IV and metronidazole 1g PR 12 hourly. Labor will be induced by an Oxytocin infusion and managed as for preterm labor. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions pre-labor rupture membranes 3 Management of PROM according to Gestational age Gestation between 34-37 weeks These patients should be discussed with the Consultant on call as be appropriate to treat them either as for preterm or as for term National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions pre-labor rupture membranes 3 Management of PROM according to Gestational age Gestation >37 weeks 1. expectant management is preferable as labor will ensure spontaneously within 24 hours in 70-90 % of these women. 2. Digital vaginal examination is not indicated. 3. IF pyrexia, offensive vaginal discharge, B hemolytic streptococcus carrier Oxytocin immediately to induce labor: Intravenous penicillin 3 g, then 1.5 g four-hourly until delivery. Clindamycin 900 mg intravenously eight-hourly if allergy Avoid Broad-spectrum antibiotics such as ampicillin, 4. If meconium, fetal tachycardia or decelerations, consider delivery by LSCS. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions pre-labor rupture membranes 3 EXPECTANT MANAGEMENT SHOULD BE : 1. Admit to antenatal bed 2. Observe 4 hourly pulse, temperature 3. Fetal heart rate CTG twice daily. 4. Vaginal examination if painful contractions start. 5. No prophylactic antibiotics. 6. Labor should be induced at 6 am approximately 24 hours after rupture of the membranes. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions pre-labor rupture membranes 3 INDUCTION OF LABOR preferably induced by PGE2 (Prostin) Nulliparous with Bishop score of < 4, should receive 3 mg prostin, Nulliparous with Bishop score of > 4 and All Multiparous should receive 1.5 mg prostin. Prostin dose can be repeated Q/6 hours up to 3 doses, 4th dose can be given after evaluation by Consultant. If the cervix is favorable, patient is transferred to labour ward and labor is induced with oxytocin. (oxytocin should be commenced after the elapse of 6 houres after the last prostin dose). If cervix remained unfavourable, patient may rest for 24 hour and another course of IOL with prostin pessaries is re-used thereafter. If after six doses of prostaglandin the cervix remains unfavorable for ARM, the mode of delivery has to be reviewed by the consultant concerned.

National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions preterm labor 4 Ethical considerations Do not suppress labor after 34 weeks in view of the excellent neonatal facilities in Tertiary Hospitals. Spontaneous miscarriages between 20 and 24 weeks gestation are usually managed in the labor ward and should be treated them as for preterm labor. However, during labor, fetal monitoring is not usually appropriate and vaginal delivery should be planned regardless of presentation. A pediatrician should be informed of the impending delivery, after 22 weeks gestation although it should be clearly explained to the parents that this is to assess the baby and not necessarily to provide active resuscitation for the baby. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions preterm labor 4 Management : Specific Actions All women with suspected preterm labor is seen by the physician Check gestation by dates and scan results. Examine to determine size and presentation Evaluate the CTG. Inform neonatal unit The following investigations are required • Full blood count • MSU-consider urgent microscopy if there is proteinuria • Speculum and intracevical swab (ICS & HVS) If membranes intact and contractions, a vaginal examination Search the etiology If membranes are ruptured refer to PROM protocol. If contractions are 3/10’ or more commence TOCOLYSIS ritodrine and give steroids National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions preterm labor 4 TOCOLYSIS : SUPPRESSION OF PRETERM LABOR 1. It is rarely indicated after 34 weeks gestation and is unlikely to be successful once cervical dilatation is 4 cms or more. 2. Only indicated in order to delay delivery by 48 hours to allow Dexamethazon in fetal maturation or to allow in utero transfer 3. If a tocolytic drug is used, ritodrine no longer seems the best choice. Atosiban or nifedipine appear preferable as they have fewer adverse effects and seem to have comparable effectiveness. Nifedipine Regimen should be the first choice now National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions preterm labor 4 TOCOLYSIS : Regimen for intravenous ritodrine infusion An infusion using a syringe pump ritodrine (Yutopar) in % dextrose. The infusion is commenced at 1 ml/hr and increased every 10 mins from 1-2-3-4-5-6 to maximum (400 µg /min) or until contractions cease or maternal pulse > 140 bpm or systolic BP>160 mmHg. Strict fluid balance records are needed urine should be tested for glucose and ketones. Pulmonary edema is recognized Once contractions have ceased the infusion is left at that rate for 1 hour The infusion is then reduced by 1 ml/hr every 30 mins until the lowest rate required keeping the patient contraction free is reached.

Primigravidae with breech presentation by CS. 3. Deliver all footling breech by CS. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Breech presentation 5 Specific Actions in case of breech presentation 1. Do not induce/and or use Oxytocin to accelerate labor. Induction or augmentation may be justified in selected cases. (Consultant decision). 2. Breech extraction ONLY in the case of a second Twin or dead fetus 3. Only senior doctor with proven experience should conduct the delivery. 4. Forceps should be available in advance. 5. When the fetal heart rate trace is suspicious, fetal blood sampling 6. An Anesthetist as well as pediatrician should attend the delivery. 7. Explain the delivery procedure to the patient and her husband. 8. Allow pregnancy to continue up to 40 weeks +10 days 9. PROM and pre-term labour are managed as in relevant protocol. National and Unified Obstetric and Newborn care Guidelines and Protocols High Risk Cases : obstetrical conditions Breech presentation 5 All women with an uncomplicated breech pregnancy at term (37-42 weeks) should be offered external cephalic version (ECV) in the absence of contraindications. 1. ECV should be undertaken by consultant or a well trained registrar under direct consultant supervision. 2. Tocolysis is helpful, and should be used as a routine in primigravidas. 3. Perform ECV while the mother awake and facilities for emergency CS delivery are available nearby. 4. Confirm fetal; well being with cardiotocography before and after ECV, Ultrasound guidance can be helpful. 5. Do not use regional anaesthesia to facilitate ECV, evidences is insufficient to support its use.
