(Approved by the ASA
House of Delegates on October 18, 2000)
This joint statement from the American Society of Anesthesiologists
(ASA) and the American College of Obstetricians and Gynecologists
(ACOG) has been designed to address issues of concern to
both specialties. Good obstetric care requires the availability
of qualified personnel and equipment to administer general
or regional anesthesia both electively and emergently. The
extent and degree to which anesthesia services are available
varies widely among hospitals. However, for any hospital
providing obstetric care, certain optimal anesthesia goals
should be sought. These include:
I. Availability of a licensed practitioner who is credentialed
to administer an appropriate anesthetic whenever necessary.
For many women, regional anesthesia (epidural, spinal
or combined spinal epidural) will be the most appropriate
anesthetic.
II. Availability of a licensed practitioner who is credentialed
to maintain support of vital functions in any obstetric
emergency.
III. Availability of anesthesia and surgical personnel
to permit the start of a cesarean delivery within 30 minutes
of the decision to perform the procedure; in cases of
VBAC, appropriate facilities and personnel, including
obstetric anesthesia, nursing personnel, and a physician
capable of monitoring labor and performing cesarean delivery,
immediately available during active labor to perform emergency
cesarean delivery (ACOG 1999). The definition of immediate
availability of personnel and facilities remains a local
decision, based on each institution's available resources
and geographic location.
IV. Appointment of a qualified anesthesiologist to be
responsible for all anesthetics administered. There are
obstetric units where obstetricians or obstetrician-supervised
nurse anesthetists administer anesthetics. The administration
of general or regional anesthesia requires both medical
judgment and technical skills. Thus, a physician with
privileges in anesthesiology should be readily available.
Persons administering or supervising obstetric anesthesia
should be qualified to manage the infrequent but occasionally
life-threatening complications of major regional anesthesia
such as respiratory and cardiovascular failure, toxic local
anesthetic convulsions, or vomiting and aspiration. Mastering
and retaining the skills and knowledge necessary to manage
these complications require adequate training and frequent
application.
To ensure the safest and most effective anesthesia for
obstetric patients, the director of anesthesia services,
with the approval of the medical staff, should develop and
enforce written policies regarding provision of obstetric
anesthesia. These include:
I. Availability of a qualified physician with obstetrical
privileges to perform operative vaginal or cesarean delivery
during administration of anesthesia. Regional and/or general
anesthesia should not be administered until the patient
has been examined and the fetal status and progress of
labor evaluated by a qualified individual. A physician
with obstetrical privileges who has knowledge of the maternal
and fetal status and the progress of labor, and who approves
the initiation of labor anesthesia, should be readily
available to deal with any obstetric complications that
may arise.
II. Availability of equipment, facilities, and support
personnel equal to that provided in the surgical suite.
This should include the availability of a properly equipped
and staffed recovery room capable of receiving and caring
for all patients recovering from major regional or general
anesthesia. Birthing facilities, when used for analgesia
or anesthesia, must be appropriately equipped to provide
safe anesthetic care during labor and delivery or post-anesthesia
recovery care.
Personnel other than the surgical team should be immediately
available to assume responsibility for resuscitation of
the depressed newborn. The surgeon and anesthesiologist
are responsible for the mother and may not be able to
leave her care for the newborn even when a regional anesthetic
is functioning adequately. Individuals qualified to perform
neonatal resuscitation should demonstrate:
A. Proficiency in rapid and accurate evaluation of
the newborn condition including Apgar scoring.
B. Knowledge of the pathogenesis of a depressed newborn
(acidosis, drugs, hypovolemia, trauma, anomalies and
infection), as well as specific indications for resuscitation.
C. Proficiency in newborn airway management, laryngoscopy,
endotracheal intubations, suctioning of airways, artificial
ventilation, cardiac massage and maintenance of thermal
stability.
In larger maternity units and those functioning as high-risk
centers, 24-hour in-house anesthesia, obstetric and neonatal
specialists are usually necessary. Preferably, the obstetric
anesthesia services should be directed by an anesthesiologist
with special training or experience in obstetric anesthesia.
These units will also frequently require the availability
of more sophisticated monitoring equipment and specially
trained nursing personnel.
A survey jointly sponsored by the ASA and ACOG found that
many hospitals in the United States have not yet achieved
the above goals. Deficiencies were most evident in smaller
delivery units. Some small delivery units are necessary
because of geographic considerations. Currently, approximately
50 percent of hospitals providing obstetric care have fewer
than 500 deliveries per year. Providing comprehensive care
for obstetric patients in these small units is extremely
inefficient, not cost-effective and frequently impossible.
Thus, the following recommendations are made:
1. Whenever possible, small units should consolidate.
2. When geographic factors require the existence of
smaller units, these units should be part of a well-established
regional perinatal system.
The availability of the appropriate personnel to assist
in the management of a variety of obstetric problems is
a necessary feature of good obstetric care. The presence
of a pediatrician or other trained physician at a high-risk
cesarean delivery to care for the newborn or the availability
of an anesthesiologist during active labor and delivery
when vaginal birth after cesarean delivery (VBAC) is attempted,
and at a breech or twin delivery are examples. Frequently,
these professionals spend a considerable amount of time
standing by for the possibility that their services may
be needed emergently but may ultimately not be required
to perform the tasks for which they are present. Reasonable
compensation for these standby services is justifiable and
necessary.
A variety of other mechanisms have been suggested to increase
the availability and quality of anesthesia services in obstetrics.
Improved hospital design to place labor and delivery suites
closer to the operating rooms would allow for more efficient
supervision of nurse anesthetists. Anesthesia equipment
in the labor and delivery area must be comparable to that
in the operating room.
Finally, good interpersonal relations between obstetricians
and anesthesiologists are important. Joint meetings between
the two departments should be encouraged. Anesthesiologists
should recognize the special needs and concerns of the obstetrician
and obstetricians should recognize the anesthesiologist
as a consultant in the management of pain and life-support
measures. Both should recognize the need to provide high
quality care for all patients.
