Insights
Placenta accreta spectrum (PAS) is rising, causing severe maternal complications and hysterectomies. Anesthesiologists are crucial for managing PAS pregnancies to improve maternal outcomes.
Area of Science:
- Obstetrics and Gynecology
- Anesthesiology
- Maternal-Fetal Medicine
Background:
- Placenta accreta spectrum (PAS) is a significant cause of obstetric hemorrhage and maternal morbidity.
- PAS is the leading indication for peripartum hysterectomy in the United States.
- The incidence of PAS has dramatically increased over the past 40 years.
Purpose of the Study:
- To provide an updated review of Placenta Accreta Spectrum (PAS).
- To outline the critical role of anesthesiologists in managing PAS.
- To cover key aspects from diagnosis to postoperative care for PAS patients.
Main Methods:
- This is a review article.
- Information was gathered on nomenclature, pathophysiology, risk factors, and antenatal detection.
- Management strategies including surgical and anesthetic approaches, intra-operative care, and postoperative plans were compiled.
Main Results:
- PAS incidence has risen from 0.03 to an estimated 0.79-3.11 per 1000 pregnancies.
- Anesthesiologists are increasingly involved in the delivery management of women with suspected PAS.
- Optimal management requires a multidisciplinary approach encompassing pre-operative, intra-operative, and postoperative care.
Conclusions:
- Placenta accreta spectrum (PAS) poses significant risks, necessitating specialized anesthetic and surgical management.
- Early detection, comprehensive pre-operative evaluation, and a coordinated surgical plan are vital for optimizing maternal outcomes.
- Anesthesiologists play a pivotal role in mitigating the severe morbidity associated with PAS.
Abstract:
Placenta accreta spectrum (PAS) is a leading contributor to major obstetric hemorrhage and severe maternal morbidity in the developed world. In the United States, PAS has become the most common cause of peripartum hysterectomy. Over the last 40 years, clinicians have also witnessed a dramatic increase in the incidence of PAS. In the 1950s, the incidence of PAS was reported to be 0.03 per 1000 pregnancies. Recent epidemiological studies estimate that the PAS incidence is between 0.79 and 3.11 in 1000 pregnancies. As a consequence, obstetric anesthesiologists are increasingly likely to be called upon to manage women with suspected PAS for delivery. Given the increasing incidence and the morbidity burden associated with PAS, anesthesiologists play a vital role in optimizing maternal outcomes for women with PAS. This review will provide up-to-date information on nomenclature, pathophysiology, risk factors, antenatal detection, systemic preparations (includes timing of delivery, location of surgery, pre-operative evaluation and patient positioning), surgical and anesthetic approach, intra-operative management, invasive radiology and postoperative plans.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
