Implementing a nurse-initiated protocol to improve response to perinatal severe hypertension.

BACKGROUND: An institutional standardized, nurse-initiated protocol was implemented to improve the recognition of and response to perinatal hypertensive emergency. OBJECTIVE(S): The primary aim was to evaluate if the rate of guideline-based treatment of perinatal hypertensive emergency improved with implementation of the protocol. STUDY DESIGN: This quality improvement initiative was developed by a multidisciplinary team and consisted of clinician and nursing education and the implementation of a standardized, nurse-initiated severe hypertension protocol. The project took place in three phases: pre-implementation (July 2020-October 2020), implementation (November 2020-June 2021), and sustainment (July 2021-May 2022). The primary aim was to increase guideline-based treatment of hypertensive emergency among pregnant and postpartum persons. Guideline-based treatment was defined as repeat blood pressure within 30 minutes of severe hypertension to diagnose hypertensive emergency, antihypertensive medication administration within 30 minutes of diagnosis, and appropriately timed repeat blood pressure following treatment. Process measures included time to confirm the diagnosis, initiate the protocol, antihypertensive medication administration, repeat blood pressure after antihypertensive medication administration, and administration of a secondary dose as appropriate. Balancing measures included maternal intensive care unit admission, clinically significant maternal hypotension, fetal demise, neonatal birthweight, and Apgar <7 at 5 minutes. Data were evaluated using between-subjects statistics and a run chart was developed to assess relationship between the protocol and changes in guideline-based treatment over time. RESULTS: Overall, 503 hypertensive emergency encounters were identified during the project period (98 [20%] pre-implementation, 172 [34%] implementation, 233 [46%] sustainment). There were higher rates of persons with chronic hypertension and who self-identified as non-Hispanic Black race in the sustainment phase compared to the other phases. Guideline-based treatment increased from 18.4% pre-implementation to 75.1% in sustainment (p<0.001). Each component of guideline-based treatment also improved significantly from pre-implementation to sustainment (p<0.001). No episodes of clinically significant maternal hypotension occurred in any phase. There were four maternal intensive care unit admissions and three fetal demises during the initiative; none were related to hypertensive emergency. CONCLUSION(S): The nurse-initiated protocol for treatment of hypertensive emergency significantly increased guideline-based treatment of perinatal hypertensive emergency, reduced time to diagnose and treat hypertensive emergency, and increased the number of patients receiving treatment when indicated. This protocol was pragmatic, utilizing resources already available on obstetric units. Use of similar protocols may be considered at institutions providing obstetric care to improve recognition of and response to hypertensive emergency which may decrease maternal and neonatal morbidity and mortality related to hypertensive emergency.

Intravenous vs Oral Acetaminophen for Analgesia After Cesarean Delivery: A Randomized Trial.

OBJECTIVE: Examination of postoperative analgesia with intravenous and oral acetaminophen. DESIGN: Prospective, three-arm, nonblinded, randomized clinical trial. SETTING: A single academic medical center. SUBJECTS: Parturients scheduled for elective cesarean delivery. METHODS: This trial randomized 141 parturients to receive intravenous acetaminophen (1 g every eight hours, three doses), oral acetaminophen (1 g every eight hours, three doses), or no acetaminophen. All patients received a standardized neuraxial anesthetic with intrathecal opioids and scheduled postoperative ketorolac. The primary outcome, 24-hour opioid consumption, was evaluated using the Kruskal-Wallace test and Tukey-Kramer adjustment for multiple comparisons. Secondary outcomes included 48-hour opioid consumption, first opioid rescue, pain scores, patient satisfaction, times to ambulation and discharge, and side effects. RESULTS: Over 18 months, 141 parturients with similar demographic variables completed the study. Median (interquartile range) opioid consumption in intravenous morphine milligram equivalents at 24 hours was 0 (5), 0 (7), and 5 (7) for the intravenous, oral, and no groups, respectively, and differed between groups (global P = 0.017). Opioid consumption and other secondary outcomes did not differ between the intravenous vs oral or oral vs no groups. Opioid consumption was reduced at 24 hours with intravenous vs no acetaminophen (P = 0.015). Patients receiving no acetaminophen had 5.8 times the odds of consuming opioids (P = 0.036), consumed 40% more opioids controlling for time (P = 0.041), and had higher pain scores with ambulation (P = 0.004) compared with the intravenous group. CONCLUSIONS: Intravenous acetaminophen did not reduce 24-hour opioid consumption or other outcomes compared with oral acetaminophen. Intravenous acetaminophen did decrease opioid consumption and pain scores compared with no acetaminophen.

Myasthenic Crisis In Pregnancy.

This case reviews the management of a 27-year-old pregnant female in myasthenic crisis. She presented to the emergency department in respiratory distress refractory to standard therapy, necessitating airway and ventilatory support and treatment with plasmapheresis. Myasthenic crisis in the setting of pregnancy is rare and presents unique management challenges for emergency physicians.
