Every year half a million parturients around the world  die as a result of their pregnancies. Another 3 million babies die as stillbirths and a further 3.8 million die as neonatal deaths.  These huge numbers of unnecessary deaths are probably not obvious to their care-providers, much less to the public in general. Obstetric providers, administrators and all who are involved in the care of this population, have a huge responsibility to bring these staggering numbers down.
From a physiological point of view, lives are sustained  through ensuring the tissue needs of the parturient or the fetus are met. The parturient's life is usually threatened ,, by massive hemorrhage, pre-eclampsia,  sepsis, thromboembolism and amniotic fluid embolism - all of which affect the delivery of oxygen to the maternal tissues. Interestingly when one moves from one country , to another regardless of economic levels, the life-threat to the parturient remains the same. Even when the causes of maternal deaths are examined over a few decades of care in the same country ,, the predominant life-threats remain fairly unchanged.
The fetus is without question more at risk of death since the pathway of oxygen from the environment to the fetal tissue is an even longer one. It is dependent on obtaining oxygen from the parturient  through the uterine blood flow, placental transfer and the intact fetal circulation.  This may explain the greater ratio of five stillbirths to every maternal death globally. All fetuses compensate for this hypoxia  by increasing their hemoglobin level, by producing fetal hemoglobin with its higher oxygen affinity and by the special phenomenon of "double Bohr" on the maternal and fetal oxygen dissociation curves to increase the gradient for better oxygen diffusion from parturient to the fetus. The hypoxia in the fetal tissue is in addition compensated for by a redesign of the fetal circulation  compared with the adult circulation to ensure more favorable oxygen flow to the brain  in preference to the other organs.
As a provider (albeit in a more limited manner than the obstetrician) of obstetric care, the well-being of both should be within our purview. Any threat to the life of the parturient might ultimately translate to a threat to the life of the fetus. Death  is part of the continuum of outcome we see in our obstetric care provision. Lesser forms of life-threat can be seen in the intensive care admissions of these parturients  or their newborn or the cerebral palsies  detected very much later in the lives of the newborn.
Strengthening care in the areas that has been flagged to be recurring annually seems like a simple measure. In reality, the lessons from these never seem to be learnt. If the lesson learnt from each maternal death is used to strengthen the systems in a hospital or a district, ultimately the level of care will definitely improve. The next parturient need not suffer the same fate as her predecessor through the same failure in the system. Protocols of care should be written and updated for these recurring events. We do know of well-written protocols/guidelines for hemorrhage,  for sepsis,  for the management of pre-eclampsia  and for cardiac disease in pregnancy which can be adapted and modified for local consumption. Drills to make providers understand how they can better perform as a team , during such life-threatening events are encouraged as a measure of improving the level of care. Senior help should be obtained sooner than later and consultants of the two disciplines, i.e., obstetric and anesthesia should be involved earlier than often is the case. Administrators can institute better support through a variety of forms including - better paging system, 24 h blood banking and instituting sepsis bundles in the hospital setting. In countries where parturients face poor access to care,  the challenge in sustaining the parturient's life may be even more daunting. Increasing the use of skilled birth attendants for parturients may potentially improve outcome.
Education and continued education to improve the culture of appropriate care , remain the mainstay. These strategies should not be limited to the providers but be extended to the education of patients  as well. Timely care  in most of these life-threats to the parturient may determine the outcome. In situations where parturients have been warned of the risk but are not acceding to the needs of admission, senior involvement to further educate the parturients of the risk is essential. Failure on the part of the parturients to cooperate with care may be due to fear of medical intervention,  lack of financial resources  and lack of faith in modern care.
There are many situations where the parturient's life may not be under threat but that of the fetus is. Most Anesthesiologists may not realize it but the life of the fetus is very much in our purview as much as it is in the obstetrician's. Recognizing the vulnerability of the fetus  and how they are compensating for the in utero hypoxic environment may be an excellent first step. Translating it further to good intrapartum monitoring , and resuscitation , especially when the signs of worsening hypoxia is occurring, would definitely go a long way to reducing the many still births, cerebral palsies and possibly peri-delivery newborn deaths. This is especially so when parturients present for high grade emergencies, prolapsed cords and abruptio placenta. Having the operation theatre in a perpetual ready state to receive the next emergency cesarean section and having a system to alert the team for a timely operative delivery would definitely cut down delays. Smaller measures , that is within our own individual care delivery practices include putting parturients in the left lateral position  during transfers, administering oxygen to the parturient as a means to improve fetal oxygenation in the fetus with worsening hypoxia, terminating the use of uterotonic agents or possibly using the tocolytics like intravenous or subcutaneous terbutaline and correcting hypovolemia or hypotension appropriately in the parturients so that uterine blood flow is not compromised. Even if we are not handling emergencies, these measures should be internalized in providers as part of our care culture with the understanding that we are handling very vulnerable beings.
Our care if inadequate  leaves a lifetime of hardship for the affected parturient or the affected newborn. We have the skills in sustaining these lives and ensuring that hypoxia or asphyxia is avoided. We may not be able to do it alone - we need the determined effort of each and every provider who is involved in the field of obstetric care to play their part as a team.  As Anesthesiologists our role in this aspect may seemingly be limited to the time of delivery, but increasingly we are now involved early in high risk pregnancy discussions and assisting in formulating correct plans , to thwart threats to the lives of both the parturient and her fetus. Encouraging the greater use of the modified early warning systems in obstetric care may also allow earlier recognition of the parturient who is unwell.
