Why is this important?
The numerous benefits of neuraxial anesthesia (spinal, epidural, combined spinal-epidural) versus general anesthesia for cesarean section are well established.
While maternal and emergent risks for general anesthesia are well known (ethnic groups; emergencies; maternal disease), Cobb et al. present the highest quality evidence to date showing obstetric anesthesia specialization is associated with a lower GA rate.
What did they do?
The researchers conducted a retrospective cohort study at a large metropolitan teaching hospital (Philadelphia, Pennsylvania) over a 4 year period, comparing general anesthesia versus neuraxial, and obstetric-specialized1 vs generalist anesthesiologists for 4,217 singleton CS deliveries.
And they found?
The total study GA rate was 9.0%. Two-thirds of CS anesthesia was provided by seven specialist obstetric anesthesiologists, versus one-third provided by 33 generalists.
Specialist obstetric anesthesiologists demonstrated a significantly lower GA rate, 7.3% vs 12.1% (OR-CI 0.45-0.79). This difference persisted for the urgent/emergent CS sub-group, though not for after-hours delivery.
Nonetheless several non-provider factors were more strongly associated with GA such as emergency CS (⇡ 7-fold), maternal medical indications for CS (⇡ 3-fold), and after-hours CS (⇡ OR 33%).
Thus care by a specialist obstetric anesthesiologist is associated with an almost-30% reduction in GA for CS .

Between the lines...
The individual obstetric-specialized anesthesiologists in this study had an almost 10-fold greater cesarean case load than did the average generalist. Whether the outcome difference was due to technical expertise, decision making or a combination, one message here is that you get better at what you do when you intentionally do more of it.

A specialized obstetric anesthesiologist was defined as having completed an obstetric anesthesia fellowship or specialist practice for at least 5 years with 33% full-time obstetric anesthesia case-load. ↩

Measuring Clinical Productivity of Anesthesiology Groups: Surgical Anesthesia at the Facility Level.
Benchmarking and comparing group productivity is an essential activity of data-driven management. For clinical anesthesiology, accomplishing this task is a daunting effort if meaningful conclusions are to be made. ⋯ Additional productivity components (total ASA units/h, h/case, h/operating room/d) allow for leaders to develop productivity dashboards. With the emergence of large groups that provide care in multiple facilities, these large groups can choose to invest more effort in collecting data and comparing facility productivity internally with group-defined measurements including total ASA units per full time equivalent.

Emerging evidence suggests that opioid use immediately after surgery and trauma may worsen outcomes. In these studies, the authors aimed to determine whether morphine administered for a clinically relevant time period (7 days) in a tibia fracture orthopedic surgery model had adverse effects on postoperative recovery. ⋯ Morphine treatment beginning at the time of injury impairs nociceptive recovery and other outcomes. Measures preventing glial activation through Toll-like receptor 4 signaling may reduce the adverse consequences of postoperative opioid administration.
