Purpose Successful resuscitation of a pregnant woman undergoing cardiac arrest and survival of the fetus require prompt, high-quality cardiopulmonary resuscitation. The objective of this observational study was to assess management of maternal cardiac arrest by anesthesia residents using high-fidelity simulation and compare subsequent performance following either didactic teaching or electronic learning (e-learning). Methods Twenty anesthesia residents were randomized to receive either didactic teaching (Didactic group,

n = 10) or e-learning (Electronic group, n = 10) on
maternal cardiac arrest. Baseline management skills were
tested using high-fidelity simulation, with repeat simulation
testing one month after their teaching intervention. The
time from cardiac arrest to start of perimortem Cesarean
delivery (PMCD) was measured, and the technical and
nontechnical skills scores between the two teaching groups
were compared.
Results The median [interquartile range] time to PMCD
decreased after teaching, from 4.5 min [3.4 to 5.1 min] to
3.5 min [2.5 to 4.0 min] (P = 0.03), although the change
within each group was not statistically significant
(Didactic group 4.9 to 3.8 min, P = 0.2; Electronic group
3.9 to 2.5 min, P = 0.07; Didactic group vs Electronic
group, P = 1.0). Even after teaching, only 65% of
participants started PMCD within four minutes. Technical
and nontechnical skills scores improved after teaching in
both groups, and there were no differences between the
groups.
Conclusion There are gaps in the knowledge and
implementation of resuscitation protocols and the
recommended modifications for pregnancy among
residents. Teaching can improve performance during
management of maternal cardiac arrest. Electronic
learning and didactic teaching offer similar benefits.
Resume
Objectif La reanimation reussie dune femme enceinte
victime dun arret cardiaque et la survie du ftus
necessitent une reanimation cardiopulmonaire rapide et de
grande qualite. Lobjectif de cette etude observationnelle
etait devaluer la prise en charge dun arret cardiaque
maternel par des residents en anesthesie utilisant une
simulation a` haute fidelite et de comparer leurs
performances apre`s un enseignement didactique ou un
apprentissage electronique (formation en ligne).
Methodes Vingt residents en anesthesie ont ete repartis
de facon aleatoire dans deux groupes : le premier a suivi
un enseignement didactique (Groupe didactique, n = 10)
et le second, une formation en ligne (Groupe electronique,
n = 10) sur larret cardiaque maternel. Les competences
initiales de prise en charge ont ete testees a` laide dune
simulation a` haute fidelite et le test de simulation a ete
repete un mois apre`s lintervention denseignement. Le
delai ecoule entre larret cardiaque et laccouchement par
cesarienne perimortem (PMCD) a ete chronometre et les
scores de competences techniques entre les deux groupes
denseignement ont ete compares.
Resultats Le delai median [ecart interquartile] jusquau
PMCD a diminue apre`s lenseignement de 4,5 min [3,4 a`
5,1] a` 3,5 min [2,5 a` 4], P = 0,03), bien que la variation a`
linterieur de chaque groupe nait pas ete significative
(groupe didactique: 4,9 a` 3,8 min, P = 0,2; groupe
electronique: 3,9 a` 2,5 min, P = 0,07; groupe didactique
contre groupe electronique, P = 1,0). Meme apre`s
lenseignement, seulement 65 % des participants ont
commence le PMCD dans un delai de quatre minutes. Les
scores techniques et non techniques ont ete ameliores apre`s
enseignement dans les deux groupes, et aucune difference
na ete trouvee entre les groupes.
Conclusion Il existe des lacunes chez nos residents quant
aux connaissances et a` la mise en uvre des protocoles de
reanimation, ainsi que dans les modifications recommandees
dans le cadre de la grossesse. Lenseignement peut ameliorer
la performance pour la prise en charge de larret cardiaque
maternel. La formation en ligne et lenseignement didactique
ont, tous deux, des avantages comparables.
Maternal cardiac arrest during pregnancy is rare, with one
case for every 20,00030,000 pregnancies.1,2 Successful
resuscitation of a pregnant woman and survival of the fetus
require prompt, high-quality cardiopulmonary resuscitation
(CPR) with some modifications in basic and advanced
cardiovascular life support techniques as they apply to
pregnancy.3,4 The term perimortem Cesarean delivery
(PMCD) refers to a Cesarean delivery concurrent with
maternal CPR.5
Katz et al. originally recommended that PMCD be
performed within four minutes of maternal cardiac arrest
and delivery of the infant by five minutes.5 A subsequent
review of published cases from 1985 to 2004 identified 38
cases of PMCD.6 Of the 22 cases where information
regarding maternal hemodynamics was provided, 12
women had sudden, often profound improvement
following delivery of the fetus. For surviving infants, there
was a suggestion that those delivered within five minutes
had a lower incidence of neurological and respiratory
sequelae. Consequently, the authors concluded that PMCD
within four minutes of maternal cardiac arrest improves
maternal and neonatal outcomes. However, these times are
an extremely tall order that is made more challenging as
maternal cardiac arrest is rare and frequently unexpected.7
Furthermore, the 20032005 Confidential Enquiry into
Maternal and Child Health (CEMACH) described
deficiencies in knowledge and poor resuscitation skills among
obstetrical caregivers and recommended that all clinical
staff undergo regular training in basic and advanced CPR.1
