Caring for the Pregnant Patient Flashcards
what are the endocrine changes in pregnancy

increased rate of respiration
what is early term
37-38 weeks and 6 days
what is full term
39-40 weeks and 6 days
what is late term
41 weeks-41 weeks and 6 days
what is post term
42 weeks and after
what are the complications in pregnancy
- spontaneous abortions
- ectopic pregnancy
- eclampsia
- anemia
- cardiovascular disease
- oral
what is the probability of spontaneous abortions and why
15% during the first trimester and possible relationship to stress or bacteremia
what is ectopic pregnancy
fertilization and implantation of the fetus in a fallopian tube, resulting in abdominal pain and heavy bleeding
what is pre eclampsia marked by
hypertensino and proteinuria
what is eclampsia marked by
malignant hypertension, seizures, and encephalopathy
what is eclampsia
a condition in which high blood pressure and proteinuria lead to encephalopathy, coma, miscarriage and death
hormonal changes can either cause:
hypertension or syncope
hypertension is monitored to screen for ____
eclampsia
since syncope can lead to traumatic injury, prodromal symptoms should be addressed by:
assuming a prone position
what is anemia in pregnancy caused by
due to increased hematologic demands
what is cardiovascular disease in pregnancy caused by
exacerbation of underlying disease in response to increased demand
what are the oral complications in pregnancy
exacerbation of underlying periodontal disease
pregnancy gingivitis and exacerbated periodontitis exacerbated by:
- lack of attention to oral hygiene
- increased systemic fluid levels and capillary fragility from increased progesterone and estrogen
- increased anaerobic bacterial plaque counts
what lesion is common in pregnancy
granulomatous reaction with a vascular component
- pyogenic granuloma
- epulis gravidarum
-pregnancy tumor
describe the pyogenic granuloma
- not an actual granuloma as there is proliferation of vascular tissues as well as proliferation of fibrous tissue
- forms submucosally and takes the shape of a nodular growth
- though to be exacerbated response to plaque and bacteria precipitated by the changes in hormonal levels
what is the treatment for pyogenic granuloma
- variable
- conservative management is an option
- may resolve post partum
- gently curettage with electrocautery
-excision to the periosteum and removal of calculus and plaque
what are the general dental guidelines during pregnancy and in each trimester
- take a history of the trimester and note complications and BP
- first trimester: fetus is especially susceptible to teratogenic influence and abortion
- second trimester: optimal trimester for dental care
- third trimester: syncope and hypertension risk are greatest secondary to fetal position. cardiovascular demands are greatest, there is increased risk of anemia, the highest risk of eclampsia, and increased risk of hypertension
when should preventative prophylaxis be done
at the beginning of the second trimester and the third trimester
all elective dental care should be:
deferred
when should nondeferrable treatment be completed and what is an example of this tx
- during second trimester
- caries control
there is no risk of fetal death, malformation, growth retardation or impairment of mental facility at what mGy
0-50 mGy
what is the fetal dose for OMR imaging
0.01mGy
an absorbed dose to the conceptus of ____ doubles the natural childhood cancer rate from 1 in 500 to 1 in 250
25mGy
absorbed dose of _____ increases the childhood cancer rate to 1 in 375
12mGy
what is the effective dose for the fetus for single intraoral F-speed rectangular radiographs
1.3 micro Sv
what is the effective dose for the fetus for 4 BW F- speed recetangular radiographs
5 micro Sv
what is the effective dose for the fetus for FMX 20 F-speed rectangular radiographs
35 micro Sv
what is the effective dose for the fetus for FMS 20 F-speed round radiographs
171 micro Sv
what is the effective dose for the fetus for FMS 20 D-speed roundradiographs
388 micro SV
what is the effective dose for the fetus for pano radiographs
9-26 micro Sv
what is the effective dose for the fetus for CBCT
20-599 micro Sv
what is the recommendation for radiographs for pregnant pts
contraindicated in all but emergency situations. when taken lead shielding is necessary
what is the protocol for new and recall pregnant dental patients
- radiographs should be postponed until post partum
- long term benefit to the health of the mother from new patient or recall exam radiographs
- BUT no benefit to the health of a developing child
- unborn child faces greater risks from the radiation exposure than the mother without any benefit to their health
what does the national council on radiation protection and measureemnts recommend
different radiation exposure thresholds for pregnant radiation workers than non pregnant radiation workers
- radiation exposure thresholds for pregnant radiation workers is lowered to the same thresholds as the general population
what is the SoD recommendation for guidelines for pregnant patients
same as NCRP recommendations
what is the patient shielding protocol during dentomaxillofacial radiology
- discontinuing shielding of the gonads, pelvic structures, and fetuses during all dentomaxillofacial radiographic imaging procedures
- thyroid shielding not be used during intraoral, panoramic, cephalometric and CBCT imaging as the risks of thyroid cancer are negligible from comtemporary maxillofacial imaging radiation doses
what is the radiograph protocol for emergency dental patients
- necessary radiographs are part of the standard of care to treat and dx a condition that threatens the health of the mother and the unborn child
- lack of radiographs compromises the emergency care dx and tx, this will directly impact the health of the unborn child
- primary beam is not directed toward the child bearing area
what are the protocols for medication
- there should be medical clearance for all drugs including LA, analgesics, and ABs
- lidocaine, penicillin, erythromycin, and acetominophen are generally approved
- aspirin and vasoconstrictors in LA and all drugs causing respiratory depression are relatively contraindicated
- diazepam, nitrous, and tetracyline are absolutely contraindicated
