3832 year old G4 P3 arrives in Labor and Delivery
in the wheelchair from the emergency room
obviously in transition. Placed into the bed and
upon inspection, feet are hanging out--- What do
you do???
39Footling Breech
40The OR is in use TWINS
41Anesthesia is staring at you!
42The head nurse is staring at you!!
43Anesthesia is sweating--
44The patient is screaming for you to GET IT OUT
What do you do?
45Take a deep Breath
46Take 30 seconds to take in the sceneryassess
the pelvis, check for a cord, send someone for
the pipers! and peds
47Anesthesia is still staring at you
48Tell her to PUSH!!!!!
49Apgars 8 -9
50So Whats the Problem??????
51TERM BREECH TRIAL COLLABORATIVE GROUP Planned
caesarean section versus planned vaginal birth
for breech presentation at term a randomised
multicentre trial. Mary E. Hannah et al. The
Lancet. Vol 356, October 21, 2000. pp1375-1383
52The term Breech Trial aimed to provide
evidence-based guidance on the controversy as to
the preferred mode of delivery of breech babies.
53- 121 Centers
- 26 countries
- Almost immediately, conclusions accepted by the
medical community - Profoundly changed medical practices around the
world
54Five years to the term breech trial the rise
and fall of a randomized controlled trial. Marek
Glezerman, MD. Am J OB-GYN (2006) 194,
20-5. Conclusion The original term breech
trial recommendations should be withdrawn. Dr.
Glezerman was chairman of one of the
participating centers that contributed patients
to the trial.
55- Lack of adherence to inclusion criteria
- Interinstitutional variation of standard of care
- Inadequate ante and intra partum fetal assessment
- Many women recruited in labor
- No attendance of a clinician with adequate
experience
56Inappropriate use of randomised trials to
evaluate complex phenomena case study of vaginal
breech delivery

57The Parachutes and Gravitational Challenge
58Evidence-Based Medicine Opportunities for
Future Study
- Parachute use to prevent death and major trauma
related to gravitational challenge - Study design
- To determine whether parachutes are effective in
preventing major trauma related to gravitational
challenge - Systematic review of randomized control clinical
trials - Medline, Hanna Databases, etc.
- Death or major trauma
59Evidence-Based Medicine Opportunities for
Future Study
- Conclusions (cont)
- We think that everyone might benefit if the most
radical protagonists of evidence-based medicine
organize AND participated in a double blind,
randomized, placebo controlled, crossover trial
of the parachute. - Smith GC, Pell JP. Parachute use to prevent death
and major trauma related to gravitational
challenge Systematic review of randomized
controlled trials. BMJ, 2003 Dec
20327(7429)1459-61.
60Evidence-Based Medicine Opportunities for
Future Study
- Findings
- No Studies identified meeting criteria
- Conclusions
- As with many interventionsthe effectiveness of
parachutes has not been subjected to rigorous
evaluation - Advocates of evidence-based medicine have
criticized the adoption of interventions
evaluated using only observational data.
61- The Term Breech Trial failed to appreciate the
- Complex nature of vaginal breech delivery
- Complex mix of operator variables necessary for
its safe conduct
62- Statistical power required a high vaginal
delivery rate - So, researchers encouraged practitioners to go
beyond their comfort level - Comfort level difficult to quantify
- Comfort level plays a pivotal part in safety of a
complex procedures - Practitioners were protected from medical
liability - Practitioners pushed their comfort levels
- This constituted a significant BIAS One of
license - Protocol allowed for .5cm/h dilatation and 3.5
hours for second stage - Few obstetricians with proved safety in vaginal
breech delivery would find them acceptable
63Widespread acceptance of this trials results has
breached the limits of evidence based medicine.
64A major limit of evidence based medicine is the
difficulty in applying the results of randomised
trials to individual patients.
65-multip -38 weeks -advanced labor -3000
grams -flexed head -no nuchal cord ----low risk
sub group
66Now, experienced Obstetricians will press for an
emergency cesarean section, not trusting their
clinical judgment because all breeches are
assigned a similar risk status by a randomised
controlled trial.
67Vaginal Breech Delivery
A Discriminating Procedure
Human skills vary Delivery technique is an
ART
68- The safe vaginal delivery requires skill in
multiple arenas - Delivery Technique
- Use of forceps if needed
- Ultrasound assessment
- Selection of cases not everyone is a candidate
- Intrapartum fetal surveillance
- Conduct of labor
- Pediatric support
- A coordinated, well functioning labor and
delivery unitBE PREPARED
69- Summary Points
- When applied to complex phenomena, randomised
trials have important limitations
70- Vaginal Breech delivery is a complex procedure
that is poorly amenable to the methods of large
multicenter randomized trials.
71- ONE randomised controlled trial has dictated a
new standard of care for vaginal breech
deliveries worldwide
72The use of a short term combined end point
overstated any true risk of planned vaginal
delivery to longer term neurodevelopmental outcome
