Acute agitation in the pregnant patient should be treated as an obstetric emergency, as it jeopardizes the safety of the patient and fetus, as well as others in the emergency room.

Uncontrolled agitation is associated with obstetric complications such as preterm delivery, placental abnormalities, postnatal death, and spontaneous abortion.1

Current data on the reproductive safety of drugs commonly used to treat acute agitation—benzodiazepines, typical (first-generation) antipsychotics, atypical (second-generation) antipsychotics, and diphenhydramine—suggest no increase in risk beyond the 2% to 3% risk of congenital malformations in the general population when used in the first trimester.2,3

Will I Pass On Asthma to My Baby?

Genetics plays a role in whether a baby will develop asthma.

In other words, asthma tends to be more likely in a baby if their relatives own it. The environment also plays an significant role.

Changes in Asthma Severity

About one-third of pregnant women with asthma will see their asthma symptoms get worse. Another third will stay the same. The lastthird will see their asthma symptoms improve.

Most women with asthmawhose symptoms changed in any way during pregnancy will return to their pre-pregnancy condition within three months after giving birth.

There is a tendency for women whose asthma symptoms increased or decreased during one pregnancy to experience the same thingin laterpregnancies.

It is hard to predict how asthma will change during pregnancy.

Because of this uncertainty,asthma should be followed closely. This way,any change can be promptly matched with an appropriate change in treatment. This calls for goodteamwork between the obstetrician, primary care physician and asthma specialist.

FIRST-GENERATION ANTIPSYCHOTICS SAFE, EFFECTIVE IN PREGNANCY

Reproductive safety of first-generation (ie, typical) neuroleptics such as haloperidol is supported by extensive data accumulated over the past 50 years.2,3,8 No significant teratogenic effect has been documented with this drug class,7 although a meta-analysis found a little increase in the relative risk of congenital malformations in offspring exposed to low-potency antipsychotics compared with those exposed to high-potency antipsychotics.2

In general, mid- and high-potency antipsychotics (eg, haloperidol, perphenazine) are often recommended because they are less likely to own associated sedative or hypotensive effects than low-potency antipsychotics (eg, chlorpromazine, perphenazine), which may be a significant consideration for a pregnant patient.2,8

There is a theoretical risk of neonatal extrapyramidal symptoms with exposure to first-generation antipsychotics in the third trimester, but the data to support this are from sparse case reports and little observational cohorts.9

Are Allergy Shots Safe During Pregnancy?

Pregnant lady with asthma already receiving allergy shot therapycan generally continueif they are not having reactions.

As an additional precaution, though, the allergist may cut thedosage of the allergy extractto reducethe chance that a severe allergic reactionoccurs or at a minimum hold the dose the same but the dose should not be increased during pregnancy since that increases the chance of a reaction.

FOCUS OF THE EMERGENCY EVALUATION

Agitation is defined as the physical manifestation of internal distress, due to an underlying medical condition such as delirium or to a psychiatric condition such as acute intoxication or withdrawal, psychosis, mania, or personality disorder.4

For the agitated pregnant lady who is not belligerent at presentation, triage should start with a basic assessment of airways, breathing, and circulation, as well as vital signs and glucose level.5 A thorough medical history and a description of events leading to the presentation, obtained from the patient or the patient’s family or friends, are vital for narrowing the diagnosis and deciding treatment.

The initial evaluation should include consideration of delirium, trauma, intracranial hemorrhage, coagulopathy, thrombocytopenia, amniotic and venous thromboembolism, hypoxia and hypercapnia, and signs and symptoms of intoxication or withdrawal from substances such as alcohol, cocaine, phencyclidine, methamphetamine, and substituted cathinones (“bath salts”).

From 20 weeks of gestation to 6 weeks postpartum, eclampsia should also be considered in the differential diagnosis.1 Ruling out these conditions is significant since the management of each differs vastly from the protocol for agitation secondary to psychosis, mania, or delirium.

NEW SYSTEM TO DETERMINE RISK DURING PREGNANCY, LACTATION

The US Food and Drug istration (FDA) has discontinued its pregnancy category labeling system that used the letters A, B, C, D, and X to convey reproductive and lactation safety.

The new system, established under the FDA Pregnancy and Lactation Labeling Rule,6 provides descriptive, up-to-date explanations of risk, as well as previously absent context regarding baseline risk for major malformations in the general population to assist with informed decision-making.7 This allows the healthcare provider to interpret the risk for an individual patient.

How Does Uncontrolled Asthma Affect the Fetus?

Uncontrolled asthma cuts the oxygen content of the mother's blood. Since the fetus gets its oxygen from the mother's blood, this can lead to decreased oxygen in the fetal blood.

The result may impair fetal growth and survival. The fetus requires a constant supply of oxygen for normal growth and development. There is evidence that adequate control of asthma during pregnancy reduces the chances of fetal or newborn death and improves fetal growth inside the uterus. There are no indications that a mother’s asthma contributes to either spontaneous abortion or congenital malformation of the fetus.

Are Asthma Medicines Safe to Use During Pregnancy?

Is It Safe to Use Asthma Inhalers or Corticosteroids While Pregnant

Ensuring asthma is well-controlled is key.

It is recommended that mothers seek regular check-ups to ensure their asthma remains controlled. Working with an asthma provider is essential. The asthma regimen that is best suited for the mom is the best approach.

Some asthma medicines are considered "safer" during pregnancy because their risks appear to be less than the risks of uncontrolled asthma. These include:

  1. Anti-leukotriene agents love montelukast (SINGULAIR®)
  2. Short-actinginhaled bronchodilators
  3. Some inhaled corticosteroids, love budesonide

Based on the severity of the mother’s asthma, a doctor may consider switching her treatment to an inhaled corticosteroid alone.

Long-acting beta agonists (like SEREVENT®, Symbicort® and ADVAIR®) and theophylline are not considered first-line treatments for pregnant asthma patients.

But doctors may consider them if the mother’s asthma is not adequately controlled by the above medicines.

If asthma is extremely severe, oral steroids such as prednisone, may be necessary for the health of the mom and baby.

Remember: It is better for mom and baby if the mom maintains asthma control (using any approved asthma drugs).

Is It Safe to Breastfeed?

Doctors do not believe asthma medicines are harmful to a nursing baby when used in usual amounts. The transfer of asthma medicines into breast milk has not been fully studied.

When breastfeeding, drinking additional liquids to avoid dehydration is also significant (as it is for every people with asthma).

Discuss with your baby’s pediatrician.

Asthma Attacks During Labor

When asthma is under control, asthma attacks almost never happen during labor and delivery. Also, mostwomen with well-controlled asthma are capable to act out breathing techniques during their labor without difficulty.

Are Flu Shots Safe to Get During Pregnancy?

People with asthma should get flu shots. Pregnancy does not change that recommendation.

In fact, influenza may be particularly severe in pregnant women.

DIPHENHYDRAMINE

Recent studies of antihistamines such as diphenhydramine own not reported any risk of major malformations with first-trimester exposure to antihistamines.13,14 Dose-dependent anticholinergic adverse effects of antihistamines can induce or exacerbate delirium and agitation, although these effects are classically seen in elderly, nonpregnant patients.15 Thus, given the paucity of adverse effects and the low risk, diphenhydramine is considered safe to use in pregnancy.13

Asthma During Pregnancy

Asthma is one of the most common medical problems that occurs during pregnancy.

It can be potentially serious. Some studies own suggested that asthma complicates up to 7% of every pregnancies.About 30% of every womenwith asthma report their asthmaworsened while pregnant.

What allergy medicine is safe during early pregnancy

Butwith the correct treatment and care, you and your baby can own a goodoutcome.

NEWER ANTIPSYCHOTICS ALSO SAFE IN PREGNANCY

Newer antipsychotics such as the second-generation antipsychotics, available since the mids, are increasingly used as primary or adjunctive therapy across a wide range of psychiatric disorders.10 Recent data from large, prospective cohort studies investigating reproductive safety of these agents are reassuring, with no specific patterns of organ malformation.11,12

What Should I Do to Avoid Asthma Attacks During Pregnancy?

Avoid Your Asthma Triggers

Avoiding asthma triggers is always significant, but is particularly significant during pregnancy.

Pregnant women with asthma should increase avoidance measures to acquire greatest comfort with the least medication.

  1. Stay away frompeople who are ill with respiratory infections.
  2. Avoidallergens love dust mites, animal dander, pollen, mold and cockroach.

Stop Smoking Cigarettes/Tobacco

Giving up cigarette smoking isimportant for any pregnant lady. Smoking may worsenasthma and harmsthe health of the growing fetus as well.

Exercise

Regular exercise is significant to health. Talk to yourobstetrician for the best adviceabout exercising during pregnancy.

Swimming isa particularly excellent exercise for people with asthma. Using quick-relief medicine10 minutes before exercise may assist you tolerate recommended exercise.

Does Asthma Cause Complications During Pregnancy?

Potential Complications

Pregnant women with asthma may havea bit greater risk of delivering early. Or the baby may own alow birth weight. High blood pressure and a related condition known as pre-eclampsiaare also more common in pregnant women with more severe asthma.

It is not known if uncontrolled asthma causes these problems directly or if other reasonsare to blame.

However, optimal control of asthma during pregnancy is the best way to cutthe risk of these complications.

Can I Do Anything to Prevent Asthma in My Baby?

One major prenatal risk factor for the development of asthma is maternal smoking.

Giving up cigarette smoking is extremely significant. Other prenatal factors that may influence the development of asthma are:
