Can you give local anesthetic to a pregnant woman?

Preventive, diagnostic and restorative dental treatment is safe throughout pregnancy. Local anesthetics with epinephrine (e.g., bupivacaine, lidocaine, mepivacaine) may be used during pregnancy.

When can you Redose lidocaine?

Based on this known half-life, surgeons should be able to safely re-dose after 1.6-2 hours. In fact, FDA administration guidelines for epidural lidocaine allow for re-dosage every 90 minutes if the initial dose does not exceed the safety threshold due to the known half-life of epidural lidocaine of 1.5-2 hours.

Do local anesthetics cross the placenta?

All the presently used local anesthetic agents in the increasingly popular modalities of obstetric regional anesthesia cross the placenta readily, governed only by two factors that the anesthesiologist has any control over (1) dosage and timing of doses and (2) uterine blood flow as it relates to the development of …

Can local anesthetic cause miscarriage?

It does not appear that anaesthetic agents have teratogenic effects in humans. However anaesthesia and surgery during pregnancy are associated with an increased risk of miscarriage, premature birth, low birth weight infants and infant death.

What pregnancy category is lidocaine?

Lidocaine: Pregnancy category B, considered relatively safe to use during pregnancy at doses used in dermatological procedures.

How do you calculate maximum local anesthetic?

The formula is as follows: maximum allowable dose (mg/kg) x (weight in kg/10) x (1/concentration of local anesthetic) = mL lidocaine. Thus, if maximal dose is 7 mg/kg for lidocaine with epinephrine, using 1% lidocaine with epinephrine for a 60-kg patient: 7 x 6 x 1 = 42 mL lidocaine.

How many mg is 2 lidocaine?

Each 2 ml solution contains 40 mg Lidocaine Hydrochloride E.P.

What anesthesia is safe during pregnancy?

The local anesthetic is transferred to the fetus slowly, and its margin of safety is also increased. Considering how local anesthetics have small direct effects on the fetus even at submaximal doses [27], lidocaine may be considered relatively safe for use in pregnant women.

Can local anesthesia cause birth defects?

Conclusions: Our study population reported a wide range of surgical procedures during pregnancy, requiring both general and local anesthesia. Our findings suggest that periconceptional anesthesia is not strongly associated with the birth defects assessed in this study.

Category B drugs include prenatal vitamins, acetaminophen and several other medications used routinely and safely during pregnancy. If there is a clinical need for a Category B drug, it is considered safe to use it.

Why do local anaesthetics increase in dosage during pregnancy?

The spread of the local anaesthetic within the epidural or spinal space is greater in pregnancy, and lower doses are required. This may be due to both the mechanical effect of the enlarging uterus and hormonal changes, increasing sensitivity to local anaesthetic agents.

What is the maximum possible concentration of local anesthetic?

Maximum values to avoid local toxicity may be much lower. – topical mucous membranes: 4.5 mg/kg per dose, not to exceed 300 mg per dose, maximum 2400 mg/24h The concentration of the local anesthetic should be known.

Is anesthetic exposure during pregnancy a teratogenic risk?

Although many pregnant women undergo anesthesia and many others are exposed by occupation to anesthetics every year, the teratogenic risk of anesthetic agents in humans must be assessed based on incomplete data.

How often do pregnant women undergo anesthesia for surgical procedures?

ESTIMATES suggest that 1% or 2% of pregnant women undergo anesthesia for surgical procedures unrelated to delivery in the United States, but pregnancy may be unrecognized at the time of surgery, and there are no formal reporting mechanisms for data collection.
