General Obstetrics and Gynecology ObstetricsMechanical ventilation in an obstetric population: Characteristics and delivery rates☆
Section snippets
Material and Methods
A retrospective chart review was performed on obstetric patients who underwent mechanical ventilation and who received care at our institutions between 1990 and 1998. The institutional review boards of both institutions approved the study before the data collection. Both centers maintain critical care obstetric (CCOB) services within the labor and delivery units for the primary treatment of critically ill patients. Patients who were transferred to the CCOB service were either patients who were
Results
There are 51 patients in this series. General characteristics of the group are listed in Table I.Most patients were undelivered on admission (84%); 69% of them were transferred specifically for CCOB services.
The specific diagnoses that led to the need for mechanical ventilation are listed in Table II.The three most frequent causes were preeclampsia/eclampsia (43%), labor/preterm labor (14%), and pneumonia (12%). Table II also distinguishes whether the patient was cared for in labor and delivery
Comment
Indications for intubation and mechanical ventilation of the obstetric patient have been well described in the literature.5, 6 These indications are similar to the nonobstetric patient population and include inadequate oxygenation, inadequate ventilation, and airway protection but are adjusted to address changes in a pregnant woman's physiologic condition.
Pulmonary and cardiovascular characteristics of gravid patients have many differences as compared to nongravid patients. A pregnant woman has
