Obstetric hemorrhage risk assessment using the maximum allowable blood loss calculation: are we on the right track?

The clinical guidelines on postpartum hemorrhage from the Society of Obstetricians and Gynaecologists of Canada (SOGC) provide evidence-based recommendations structured around the 6Rs framework: Risk Assessment, Risk Reduction, Recognition and Evaluation, Reaction, Resuscitation, and Review. Since its publication, our institution has begun implementing all the guideline recommendations. One key recommendation is to calculate the Maximum Allowable Blood Loss (MABL) to reach a hemoglobin level of 70 g/L for every obstetric patient.

Anesthetic management of neurosurgical procedures during pregnancy: a case series.

Introduction: Neurosurgical disorders are rare during pregnancy and challenge the anesthesiologist with conflicting anesthetic considerations and little evidence to guide decision-making. Our objective was to review the anesthetic management of pregnant patients undergoing intracranial neurosurgery at our institution and to describe the perioperative complications and outcomes.

Methods: We used our institutional Discharge Abstract Database to identify patients assigned both neurological and obstetrical International Classification of Disease 10-A codes between April 1, 2001 and March 1, 2012.
