Cesarean Delivery Outcomes for Patients with Coronavirus Disease-2019 in the USA.

INTRODUCTION: Coronavirus disease-2019 (COVID-19) may have increased morbidity and mortality in patients having Cesarean delivery (CD) in the USA. METHODS: We performed a retrospective cohort study of patients who had CD in 2020 using the national inpatient sample. After stratification by COVID-19 status, demographics, comorbidities, complications, mortality, and costs were compared. RESULTS: There were 31,444,222 hospitalizations in the USA in 2020 with a mortality rate of 2.8%. Among these, 1,453,945 patients had COVID-19 and mortality was 13.2%. There were 1,108,755 patients who had CD and 15,550 had COVID-19. Patients with COVID-19 more frequently had Medicaid and were Hispanic. Patients with COVID-19 had more comorbidities including chronic hypertension, diabetes mellitus, pre-eclampsia, and eclampsia. Mortality in CD patients with COVID-19 was 30 in 10,000 patients, while for non-COVID-19 patients, it was 1 in 10,000 patients, P < 0.001. The crude odds ratio for mortality in COVID-19 patients was 32.1 (95% confidence interval = 22.9 to 44.7), P < 0.001 and the adjusted odds ratio was 29.3 (95% confidence interval = 20.7 to 41.4), P < 0.001. CONCLUSIONS: CD patients with COVID-19 had 30-fold higher mortality before widespread vaccination was available with Hispanic and Medicaid patients disproportionately impacted. Potential explanations for this disparity include reduced access to personal protective equipment (e.g., masks) and testing, as well as socio-economic factors. Further research is needed to understand the factors that contributed to disparities in infection and clinical outcomes among obstetric patients during the COVID-19 pandemic. In future pandemics, enhanced efforts will be needed to protect economically disadvantaged women who are pregnant.

Etiology, management, and sequela of postdural puncture headache.

PURPOSE: The purpose of this article is to provide readers with a concise overview of the cause, incidence, treatment of, and sequalae of postdural puncture headaches (PDPH). Over the past 2 years, much data has been published on modifiable risk factors for PDPH, treatments for PDPH, and sequalae of PDPH particularly long-term. RECENT FINDINGS: There is emerging data about how modifiable risk factors for PDPH are not as absolute as once believed. There have been several new meta-analysis and clinical trials published, providing more data about effective therapies for PDPH. Significantly, much recent data has come out about the sequalae, particularly long-term of dural puncture. SUMMARY: Emerging evidence demonstrates that in patients who are at low risk of PDPH, needle type and gauge may be of no consequence in a patient developing a PDPH. Although epidural blood patch (EBP) remains the gold-standard of therapy, several other interventions, both medical and procedural, show promise and may obviate the need for EBP in patients with mild-moderate PDPH. Patients who endure dural puncture, especially accidental dural puncture (ADP) are at low but significant risk of developing short term issues as well as chronic pain symptoms.

Effect of enhanced recovery after surgery for elective cesarean deliveries on neonatal outcomes.

OBJECTIVE: To evaluate the impact of initiation of an enhanced recovery after cesarean delivery (ERAC) protocol for elective cesarean delivery (CD) on neonatal outcomes. STUDY DESIGN: We performed a retrospective analysis of elective CD at ≥39 weeks gestational age between September 2014 and August 2018 at a single institution before and after ERAC protocol implementation. Our primary outcome was composite neonatal complication rate and secondary outcome was rate of breastfeeding. We performed univariate analyses to detect differences in outcomes between the pre-ERAC and post-ERAC groups. RESULTS: We included 362 neonates born via elective CD before (n = 135) and after (n = 227) ERAC implementation. The post-ERAC group experienced fewer composite neonatal complications (33.0% vs. 47.4%, p = 0.009) and greater breastfeeding rates (80.2% vs. 67.4%, p = 0.009) compared to the pre-ERAC group. CONCLUSION: ERAC protocol implementation does not negatively impact neonates and may benefit both mother and baby.

Extracorporeal Membrane Oxygenation Therapy After Amniotic Fluid Embolism With Undetectable ROTEM FIBTEM Activity: A Case Report.

Amniotic fluid embolism (AFE) is a rare but devastating condition with mortality rates as high as 60%-80%., We report a case of AFE complicating the labor of a parturient with no reported risk factors. She received general anesthesia for emergent cesarean delivery (CD), after which she developed a pulseless electrical activity (PEA) event requiring resuscitation, disseminated intravascular coagulation, and postpartum hemorrhage with undetectable fibrinogen activity by ROTEM FIBTEM assay. Extracorporeal membrane oxygenation (ECMO) therapy was successfully initiated, and she was discharged home without neurologic sequelae. ECMO therapy can be considered for the treatment of AFE even in the absence of fibrinogen activity.

Feasibility of Spinal Anesthesia Placement Using Automated Interpretation of Lumbar Ultrasound Images: A Prospective Randomized Controlled Trial.

BACKGROUND: This study evaluated the efficacy of spinal anesthesia administration by resident physicians when using an ultrasound system with automated neuraxial landmark detection capabilities. METHODS: 150 patients were enrolled in this trial. Anesthesiology residents placed spinals in subjects undergoing scheduled cesarean delivery using one of three techniques to identify neuraxial landmarks: palpation, ultrasound, or combined palpation and ultrasound. Ultrasound was performed using a handheld system that automatically identified neuraxial landmarks (e.g. midline, intervertebral spaces). All residents watched a 10-minute video and received 20 minutes of hands-on training prior to participating in the study. First insertion success rate was the primary end point. RESULTS: Among all patients, use of ultrasound resulted in a 11% greater first-insertion success rate (RR: 1.11 [0.85-1.47], p=0.431), a 15% reduction in needle insertions (RR: 0.85, p=0.052), and a 26% decrease in needle passes (RR: 0.74, p=0.070). In obese patients of BMI ≥ 30 kg/m2, use of ultrasound resulted in 26% greater first-insertion success rates (RR: 1.26, p=0.187), a 21% decrease in needle insertions (RR: 0.79, p=0.025), a 38% decrease in needle passes (RR: 0.62, p=0.030), and a 75% decrease in patients reporting neutral or low patient satisfaction with anesthesia administration (RR: 0.25, p=0.004). DISCUSSION: Resident anesthesiologists competently utilized the ultrasound system after receiving minimal training. Technical endpoints and patient satisfaction trended towards improvement when ultrasound was used prior to spinal placement, with stronger trends observed in obese patients. Additional study is required to fully characterize the impact of the ultrasound system on clinical efficacy.

A Case Report of Recurrent Severe Peripartum Cardiomyopathy Complicated by Factor V Leiden and Multiple Endocrine Neoplasia Type 1: A Management Conundrum.

Cardiovascular disease is the leading cause of peripartum death in the United States during pregnancy. The presence of concomitant diagnoses may complicate or conflict with the management of the primary cardiovascular diagnosis and further complicate pregnancy and delivery. We describe the management of a 29-year-old, gravida 5, para 1 woman with severe peripartum cardiomyopathy during this and a previous pregnancy complicated by multiple endocrine neoplasia type and factor V Leiden thrombophilia, limiting therapeutic options and contributing to considerable perioperative management challenges.

Effects of hydroxyethyl starch 6 % (130/0.4) on blood loss during cesarean delivery: a propensity-matched analysis.

BACKGROUND: Hydroxyethyl starch is commonly used in the obstetric patient population to prevent hypotension during cesarean delivery. Evidence suggests hetastarch is associated with a dysfunction in coagulation cascade. We hypothesized that hetastarch use to prevent spinal hypotension during cesarean delivery would be associated with an increase in blood loss when compared to crystalloid use. METHODS: We performed a retrospective review of patients who underwent elective cesarean delivery under spinal anesthesia at the University of Virginia between 2011 and 2014. Data from 819 patients was used. Blood loss was the primary outcome. Propensity score-matching was used to match patients who received hetastarch (treatment group) with those who did not receive hetastarch (control group). RESULTS: Genetic matching resulted in 196 patients in the hetastarch group and 182 patients in the control group. There was no difference in estimated blood loss (p = 0.068), calculated blood loss (p = 0.720), total intraoperative fluid intake (p = 0.289), urine output (p = 0.421), Apgar 1 min (p = 0.830), Apgar 5 min (p = 0.138), phenylephrine consumption (p = 0.742), postoperative day 1 (POD1) hematocrit (p = 0.070) and POD1 platelets (p = 0.233). However, there was a statistically significant difference (but clinically irrelevant) in hematocrit difference between the day of admission and POD1 (mean difference 0.47, p = 0.024), and ephedrine consumption (mean difference 2 mg, p = 0.017) in favor of the control group. CONCLUSIONS: Our study did not find an association between increased perioperative blood loss and hetastarch use in patients presenting for elective cesarean delivery.
