Evidence based c

  1. 1. Evidence Based C.S evidence that matters
  2. 2. Introduction <ul><li>Good doctors rely on both their expertise and the evidence in providing their patients with the best care possible </li></ul>
  3. 3. Evidence that matters <ul><li>Meaning focusing the efforts to find evidence that is more practical and useful to the patient </li></ul><ul><li>patient-oriented evidence </li></ul>
  4. 4. C.S <ul><li>defined as the birth of a fetus through incisions in the abdominal wall (laparotomy) </li></ul>
  5. 5. Frequency : Increased <ul><li>Reduced parity </li></ul><ul><li>Older women are having children </li></ul><ul><li>Electronic fetal monitoring </li></ul><ul><li>Breech presentations </li></ul><ul><li>The incidence of midpelvic vaginal deliveries has decreased </li></ul><ul><li>Malpractice litigation </li></ul><ul><li>Socioeconomic and demographic factors </li></ul>
  6. 6. Problems with Evidence <ul><li>Surgical techniques vary widely </li></ul><ul><li>Randomised trials comparing different techniques are limited: </li></ul><ul><ul><li>small sample sizes </li></ul></ul><ul><ul><li>short-term follow-ups </li></ul></ul><ul><ul><li>Many existing trials have methodological problems </li></ul></ul>
  7. 7. <ul><li>The operating table for CS should have a lateral tilt of 15 degrees, because this reduces maternal hypotension. </li></ul>
  8. 8. Incision <ul><li>The transverse incision of choice should be the Joel Cohen incision (subsequent tissue layers are opened bluntly </li></ul><ul><li>because it is associated with shorter operating times and reduced postoperative febrile morbidity. </li></ul>
  9. 9. Uterine incision <ul><li>blunt rather than sharp extension of the uterine incision should be used because it reduces blood loss, incidence of postpartum haemorrhage </li></ul>
  10. 10. Placenta <ul><li>At CS, the placenta should be removed using controlled cord traction and not manual removal as this reduces the risk of endometritis. </li></ul>
  11. 11. Exteriorisation <ul><li>Intraperitoneal repair of the uterus at CS should be undertaken. Exteriorisation of the uterus is not recommended because it is associated with more pain and does not improve operative outcomes such as haemorrhage and infection. </li></ul>
  12. 12. Single versus double layer closure of the uterus <ul><li>96% of obstetricians in UK report closing uterus in 2 layers </li></ul><ul><li>Incidence of rupture uterus is reported to be higher with single layer closure </li></ul>
  13. 13. <ul><li>Neither the visceral nor the parietal peritoneum should be sutured at CS because this reduces operating time, the need for postoperative analgesia and improves maternal satisfaction. </li></ul>
  14. 14. SC tissue <ul><li>Routine closure of the subcutaneous tissue space should not be used, unless the woman has more than 2 cm subcutaneous fat, because it does not reduce the incidence of wound infection. </li></ul>
  15. 15. Drains <ul><li>Superficial wound drains should not be used at CS because they do not decrease the incidence of wound infection or wound haematoma. </li></ul>
  16. 16. Antibiotics <ul><li>prophylactic antibiotics should be offered,, to reduce the risk of postoperative infections (such as endometritis, urinary tract and wound infection) which occurs in about 8% of women who have had a CS. </li></ul>
  17. 17. Breech presentation <ul><li>Women who have an uncomplicated singleton breech pregnancy at 36 weeks gestation should be offered external cephalic version. </li></ul>
  18. 18. Do CS <ul><li>Pregnant women with a singleton breech presentation at term, for whom external </li></ul><ul><li>cephalic version is contraindicated or has been unsuccessful, should be offered CS as it reduces perinatal mortality and neonatal morbidity. </li></ul>
  19. 19. Multiple pregnancy <ul><li>perinatal morbidity and mortality is increased for the second twin. </li></ul><ul><li>However, the effect of planned CS in improving outcome for the second twin remains uncertain </li></ul>
  20. 20. Twin <ul><li>In twin pregnancies where the first twin is not cephalic the effect of CS in improving outcome is uncertain but current practice is to offer a planned CS. </li></ul>
  21. 21. 38ws <ul><li>Planned CS for uncomplicated twin pregnancy should not be carried out before 38 weeks because this increases the risk of respiratory problems </li></ul>
  22. 22. Preterm birth <ul><li>Preterm birth is associated with higher neonatal morbidity and mortality. </li></ul><ul><li>However, the effect of planned CS in improving these outcomes remains uncertain </li></ul>
  23. 23. Small for gestational age <ul><li>The risk of neonatal morbidity and mortality is higher with ‘small for gestational age’ babies. </li></ul><ul><li>However, the effect of planned CS in improving this outcome remains uncertain </li></ul>
  24. 24. Predicting CS for cephalopelvic disproportion in labour <ul><li>maternal height and estimations of fetal size (ultrasound or clinical examination) do not accurately predict cephalopelvic disproportion and should not be used to predict “failure to progress” during lab </li></ul>
  25. 25. Hepatitis C <ul><li>Pregnant women who are co-infected with hepatitis C virus should be offered a planned CS as this reduces the mother-to-child-transmission of hepatitis C virus. </li></ul>
  26. 26. It is a Laparotomy <ul><li>Maternal request is not on its own an indication for CS </li></ul>
  27. 27. Breastfeeding <ul><li>ASAP. </li></ul><ul><li>This is because women who have had a CS are less likely to start breastfeeding in the first few hours after the birth, but, when breastfeeding is established, they are as likely to continue as women who have a vaginal birth. </li></ul>
  28. 28. NSAD <ul><li>Providing there is no contraindication, nonsteroidal anti-inflammatory drugs should be offered post-CS as an adjunct to other analgesics, because they reduce the need for opioids. </li></ul>
  29. 29. To Eat or not to Eat <ul><li>Women who are recovering well after CS and who do not have complications can eat and drink when they feel hungry or thirsty. </li></ul>
  30. 30. Discharge <ul><li>women who are recovering well following CS should be offered early discharge (after 24 hours) from hospital. </li></ul>
