The Society for Obstetric Anesthesia and Perinatology Research Network General Anesthesia Registry
What this study is about
The SOAP registry is a forward-looking, conducted at multiple hospitals, electronic registry. The goal is to investigate the indications, mode of airway management, predisposing factors, and obstetric and anesthetic outcomes of pregnant patients who receive general anesthesia for cesarean delivery.
View original scientific description
The SOAP registry is a prospective, multicenter, electronic registry. The goal is to investigate the indications, mode of airway management, predisposing factors, and obstetric and anesthetic outcomes of pregnant patients who receive general anesthesia for cesarean delivery.
Primary outcome measures
Rates of General Anesthesia for Cesarean Delivery
Time frame: Up to 5 years
The rates of general anesthesia for cesarean delivery among the institutions in the cohort will be assessed. Descriptive analyses of etiologies of and management of general anesthetics for cesarean delivery will also be performed.
Univariate Association Between Facility Type and the Rate of General Anesthesia for Cesarean Delivery
Time frame: Up to 5 years
The association between facility type- non-academic affiliated private vs. academic affiliated private vs. military vs. academic (reference)- with a difference in rates of general anesthesia for cesarean delivery will be assessed.
Univariate Association Between SOAP Center of Excellence Designation and the Rate of General Anesthesia for Cesarean Delivery
Time frame: Up to 5 years
The association between SOAP center of excellence designation- yes (reference) vs. no- with a difference in rates of general anesthesia for cesarean delivery will be assessed.
Univariate Association Between Maternal Level of Care and the Rate of General Anesthesia for Cesarean Association
Time frame: Up to 5 years
The association between maternal level of care- I vs. II vs. III vs. IV (reference)- with a difference in rates of general anesthesia for cesarean delivery will be assessed.
Univariate Association Between Annual Live Births and the Rate of General Anesthesia for Cesarean Delivery
Time frame: Up to 5 years
The association between increased numbers of annual live births (continuous variable) and a difference in rates of general anesthesia for cesarean delivery will be assessed.
Univariate Association Between Obstetric Anesthesiologist Coverage and the Rate of General Anesthesia for Cesarean Delivery
Time frame: Up to 5 years
The association between increased rates of labor and delivery floor coverage by obstetric anesthesiologists (continuous variable) and a difference in rates of general anesthesia for cesarean delivery will be assessed.
Univariate Association Between Institutional Policies for Labor Epidural Management and the Rate of General Anesthesia for Cesarean Delivery
Time frame: Up to 5 years
The association between the presence of institutional policies for labor epidural management- yes (reference) vs. no- and a difference in rates of general anesthesia for cesarean delivery will be assessed.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
