The Scope of the Problem…. In the World ~600,000 women die
each year as a result of pregnancy and childbirth
1600 women die each day
One woman dies every minute
![Page 5: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/5.jpg)
In the U.S……
![Page 6: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/6.jpg)
The Scope of the Problem….
In the US ~6 million US women become
pregnant/year, >10,000 give birth/day 2-3 die of pregnancy related causes/day Risk of death varies greatly in different racial
and ethnic groups

Sentinel Event Alert Issue 44: Preventing Maternal DeathJanuary 26, 2010
…the most common preventable errors are: Failure to adequately control blood pressure in
hypertensive women Failure to adequately diagnose and treat
pulmonary edema in women with pre-eclampsia Failure to pay attention to vital signs following
Cesarean section Hemorrhage following Cesarean section

condition worsens Written criteria: early warning signs,
when to seek help Staff seek assistance when concerned Family seek assistance when concerned

Key Assessments
![Page 16: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/16.jpg)
What Are The Signs of Maternal Deterioration?
KEY ASSESSMENTS Heart rate over 100 beats/min Systolic BP over 160 mmHg or
under 90 mmHg Diastolic BP over 80 mmHg Temperature over 38°C (100.4° F) Respiratory rate over 21 breaths/min
Over 30 breaths/min indicates serious illness
![Page 17: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/17.jpg)
KEY ASSESSMENT: Heart Rate
Count HR for 1 minute with stethoscope at apex of heart for high risk patient
Investigate cause of tachycardia: Pain, stress, fever, medication including recreational drugs, CV/pulmonary compromise
For patients with a history of cardiac disease: Report irregular rate (rule out arrhythmia) Report if consistently above 100 (may interfere
with cardiac output)
![Page 18: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/18.jpg)
KEY ASSESSMENT: Blood Pressure Measurement
Most accurate position for BP is sitting or semi-sitting
May be 10-12 mmHg difference in superior and inferior arm when pt side-lying
![Page 19: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/19.jpg)
KEY ASSESSMENT: Respiratory Rate
Count rate for 1 minute with stethoscope for high risk patients
Other assessments: Breath sounds, SaO2, dyspnea (speech pattern), pt posture,cough
Sustained RR of 35-40, indication for evaluation for intubation
![Page 20: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/20.jpg)
KEY ASSESSMENT: Pulse Pressure
Pulse pressure (PP) = difference between systolic and diastolic BP
in PP seen with exercise, anxiety, bradycardia, anemia, fever, HTN, pulmonary edema, aortic coarctation
↓ in PP seen with hemorrhage Narrowing PP occurs with rising diastolic BP
![Page 21: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/21.jpg)
KEY ASSESSMENT: The Fetus
Fetus = the “miner’s canary” Fetal tachycardia may indicate early fetal
hypoxemia, late decelerations indicate uteroplacental insufficiency
FHR accelerations and/or moderate variabilityadequate cerebral oxygenationadequate placental perfusion = maternal perfusion
![Page 22: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/22.jpg)
KEY ASSESSMENT: Neurologic Assessment
Glasgow Coma Scale: Objective assessment of level of consciousness 7 points or less found in comatose pt
Use scale for neurologic assessment that is used by local ICU
![Page 23: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/23.jpg)
““The weakest link in patient care is the tendency The weakest link in patient care is the tendency of the clinician to convince himself or herself of the clinician to convince himself or herself that somehow everything will be alright”that somehow everything will be alright”

Recognition of life threatening illness can be challenging
Physiologic changes of pregnancy can mask development of serious illness

Early Warning System
Assessment of: Mental status Heart rate Respiratory rate Systolic blood pressure Temperature
Documentation strategy that assists in alerting the bedside provider to changes in patient status

Selected Recommendations
“….detection of life threatening illness alone is of little value. It is the subsequent management that will alter the outcome.”

![Page 49: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/49.jpg)
Selected Recommendations
Preconception care for women with pre-existing serious medical or mental health condition or obesity
Treatment of systolic BP of 160 or greater with anti-hypertensive, possibly earlier if clinical picture suggests rapid deterioration
Cesarean may be the safest birth for some but is not risk free
![Page 50: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/50.jpg)
Selected Recommendations
All clinical staff need to learn from critical events or serious untoward incidents
All clinical staff need to have regular information and training on identification, management and referral of serious conditions
Early warning scoring systems should be adapted and used to alert staff to worsening clinical condition
![Page 51: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/51.jpg)
Selected Recommendations
Identification and management of hemorrhage should be reviewed with staff including use of in-situ drills
Encourage and practice open communication between all staff
Standardize and centralize documentation Develop guidelines or algorithms to guide
management of serious conditions
![Page 52: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/52.jpg)
Selected Recommendations
Guidelines/best practices for preconception management of obese women established
Promote attainment of healthy pre-pregnancy weight, appropriate weight gain during pregnancy through better nutrition and increased activity
CA-PAMR 2011
![Page 53: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/53.jpg)
Selected Recommendations
Measures to prevent blood clots for all women undergoing cesarean delivery
Education - health risks of primary and subsequent cesarean birth
Causes of death found more preventable: obstetric hemorrhage, sepsis/infection, and preeclampsia/eclampsia
Direct, set priorities for statewide quality improvement efforts
![Page 54: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/54.jpg)
Selected Recommendations
Help health care providers recognize and respond to critical clinical obstetric events
Identify and manage maternal risk factors, including obesity, hypertension and underlying heart disease
Improve the ability of health care facilities to respond to obstetric emergencies
![Page 55: Recognition of Deterioration of Maternal Status Julie Arafeh MSN, RN.](https://reader035.fdocuments.in/reader035/viewer/2022062409/56649cdd5503460f949a832d/html5/thumbnails/55.jpg)
