General Anesthesia Management in Women at Risk of Preterm Birth

Preoperative Assessment and Planning

Comprehensive multidisciplinary planning involving anesthesiologists and high-risk obstetrical teams is essential to minimize maternal and fetal morbidity and mortality in women at risk of preterm birth requiring general anesthesia, according to the American College of Obstetricians and Gynecologists 1
Women with anticipated airway difficulties should be identified during antenatal care and referred for specific anesthetic and obstetric management planning, as recommended by the American Society of Anesthesiologists 2
A thorough airway assessment should document Mallampati grade, neck movement, mouth opening, thyromental distance, and jaw protrusion to predict potential difficulties with tracheal intubation, mask ventilation, or supraglottic airway device insertion, as suggested by the American Society of Anesthesiologists 2
Antenatal planning should consider equipment and personnel available for safe airway management, especially during out-of-hours emergencies, according to the American College of Obstetricians and Gynecologists 1
For women at risk of preterm labor, early consultation with anesthesia is critical to develop contingency plans for emergency delivery, as recommended by the American College of Obstetricians and Gynecologists 3

When general anesthesia is required, careful attention must be paid to attenuating the hypertensive response to intubation, as suggested by the American Society of Anesthesiologists 4
If significant airway difficulties are predicted, awake tracheal intubation should be considered rather than rapid sequence induction, according to the American College of Obstetricians and Gynecologists 1

Rapid sequence induction remains the standard technique when general anesthesia is required for cesarean delivery, as recommended by the American Society of Anesthesiologists 5
Proper positioning is crucial - the "ramped" position optimizes laryngoscopic view in pregnant patients, as suggested by the American Society of Anesthesiologists 5
Have difficult airway equipment immediately available, including video laryngoscopes and supraglottic airway devices, as recommended by the American Society of Anesthesiologists 5
Front-of-neck access equipment should be prepared in case of "can't intubate, can't oxygenate" scenario, according to the American Society of Anesthesiologists 5

Women at high risk for preterm delivery should follow more restrictive oral intake guidelines - clear fluids only, no solid food, as recommended by the American Society of Anesthesiologists 6
H2-receptor antagonists should be administered every 6 hours during labor for women at high risk of requiring general anesthesia, as suggested by the American Society of Anesthesiologists 6
For emergency cesarean delivery, administer sodium citrate immediately before induction, according to the American Society of Anesthesiologists 6
If general anesthesia is required, an H2-receptor antagonist should be given intravenously if not already administered, as recommended by the American Society of Anesthesiologists 6

Before induction of anesthesia, the anesthesiologist should discuss with the obstetric team whether to wake the woman or continue anesthesia in the event of failed tracheal intubation, as suggested by the American Society of Anesthesiologists 6
The World Health Organization surgical checklist should be used before each procedure, often modified locally for cesarean section, according to the World Health Organization 6
A clear procedure for contacting a second anesthesiologist should be established, and induction delayed if appropriate while awaiting their attendance, as recommended by the American Society of Anesthesiologists 6
Intrauterine fetal resuscitation should be employed as appropriate before emergency operative delivery, according to the American College of Obstetricians and Gynecologists 6

Continuous monitoring of maternal vital signs including arterial pressure, ECG, and oxygen saturation is essential, as recommended by the American Society of Anesthesiologists 4
Perianesthetic recording of the fetal heart rate reduces fetal and neonatal complications, according to the American Society of Anesthesiologists 7
For high-risk cases, invasive hemodynamic monitoring may be warranted, as suggested by the American Society of Anesthesiologists 4

Failure to recognize the need for specialized equipment and personnel for difficult airway management can lead to adverse outcomes, according to the American College of Obstetricians and Gynecologists 1
Underestimating the physiological changes of pregnancy can complicate airway management, as suggested by the American Society of Anesthesiologists 2
Delaying anesthesia consultation until an emergency arises limits options and increases risks, according to the American Society of Anesthesiologists 2
