RESUMEN
The pregnancy-related mortality rate in the United States is excessively high. The American Heart Association is dedicated to fighting heart disease and recognizes that cardiovascular disease, preexisting or acquired during pregnancy, is the leading cause of maternal mortality in the United States. Comprehensive scientific statements from cardiology and obstetrics experts guide the treatment of cardio-obstetric patients before, during, and after pregnancy. This scientific statement aims to highlight the role of specialized cardio-obstetric anesthesiology care, presenting a systematic approach to the care of these patients from the anesthesiology perspective. The anesthesiologist is a critical part of the pregnancy heart team as the perioperative physician who is trained to prevent or promptly recognize and treat patients with peripartum cardiovascular decompensation. Maternal morbidity is attenuated with expert anesthesiology peripartum care, which includes the management of neuraxial anesthesia, inotrope and vasopressor support, transthoracic echocardiography, optimization of delivery location, and consideration of advanced critical care and mechanical support when needed. Standardizing the anesthesiology approach to patients with high peripartum cardiovascular risk and ensuring that cardio-obstetrics patients have access to the appropriate care team, facilities, and advanced cardiovascular therapies will contribute to improving peripartum morbidity and mortality.

BACKGROUND: Enhanced recovery after surgery (ERAS) pathways utilize multimodal analgesia. In pathways already utilizing incisional injection of liposomal bupivacaine (ILB), we assessed the benefit of adding intrathecal opioid analgesia (ITA). METHODS: In this randomized controlled non-inferiority trial in patients undergoing laparotomy for gynecologic malignancy, we allocated patients 1:1 to ILB alone versus ITA + ILB with 150 µg intrathecal hydromorphone. The primary endpoint was the Overall Benefit of Analgesia Score (OBAS) at 24 h following surgery. Secondary endpoints included pain scores, intravenous opioid use, and cost of care. RESULTS: Demographic and surgical factors were balanced for 105 patients. For the primary endpoint, ILB alone was non-inferior to ITA + ILB (median OBAS at 24 h of 4 vs 4; p = 0.70). We observed a significant reduction in the need for intravenous opioids (26% vs 71%; p < 0.001) and total opioid requirements (median 7.5 vs 39.3 mg morphine equivalents, p < 0.001) in the first 24 h. Clinically relevant improvements in pain scores were identified in the first 16 h after surgery favoring ITA + ILB. Total cost of the index episode, pharmacy costs, and costs at 30 days were not statistically different. CONCLUSIONS: Using OBAS as the primary endpoint, ILB alone was non-inferior to ITA + ILB. However, important cost-neutral benefits for ITA + ILB in the first 24 h post-operatively included lower pain scores and reduced need for intravenous opioids. These early, incremental benefits of adding ITA to ERAS bundles already utilizing ILB should be considered to optimize immediate post-operative pain.
RESUMEN
INTRODUCTION: Congenital hydrocephalus often results in irreversible and severe damage to the brain despite postnatal interventions. The potential for prenatal intervention to mitigate these deleterious effects underscores the importance of a suitable animal model. We aimed assess the results of an ultrasound guided transuterine approach to replicate the BioGlue injection fetal hydrocephalus model. METHODS: Pregnant ewes were anesthetized at 95 days of gestation and BioGlue was injected into the fetal cisterna magna under ultrasound guidance through the uterus. Ventriculomegaly was assessed by MRI and histology. RESULTS: Nine pregnant ewes were included in the study, and their fetuses were divided into the the BioGlue intervention group (n=9 fetuses) or the control group (n=7 fetuses) who were not injected. Although hydrocephalus was noted in 5 of 9 fetuses in the intervention group, the ability to induce hydrocephalus went from 0% to 100% in the last 3 fetuses following technical modifications. None of the controls developed hydrocephalus. Fetal brains with hydrocephalus demonstrated increased IBA1+ compared to control animals. CONCLUSIONS: While technical challenges were noted, the ultrasound guided transuterine approach to replicate the BioGlue fetal hydrocephalus model in sheep showed consistent and reproducible results. This model offers the advantage of directly visualizing the location of the needle tip and injection of the BioGlue. This technique offers an alternative for testing novel approaches for prenatal congenital hydrocephalus treatment.
RESUMEN
PURPOSE: Protocol-driven oxytocin regimens can reduce oxytocin administration compared with a nonprotocol free-flow continuous infusion. Our aim was to compare secondary uterotonic use between a modified "rule of threes" oxytocin protocol and a free-flow continuous oxytocin infusion after Cesarean delivery. METHODS: We conducted a retrospective before-and-after study to compare patients who underwent Cesarean delivery between 1 January 2010 and 31 December 2013 (preprotocol) with patients who underwent Cesarean delivery between 1 January 2015 and 31 August 2017 (postprotocol). The preprotocol group received free-flow oxytocin administration and the postprotocol group received oxytocin according to a modified rule of threes algorithm. The primary outcome was secondary uterotonic use and the secondary outcomes included blood transfusion, hemoglobin value < 8 g·dL-1, and estimated blood loss. RESULTS: In total, 4,010 Cesarean deliveries were performed in 3,637 patients (2,262 preprotocol and 1,748 postprotocol). The odds of receiving secondary uterotonic drugs were increased in the postprotocol group (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.04 to 1.70; P = 0.02). Patients in the postprotocol group were less likely to receive a blood transfusion. Nevertheless, the two groups were similar for the composite end point of transfusion or hemoglobin < 8 g·dL-1 (OR, 0.86; 95% CI, 0.66 to 1.11; P = 0.25). The odds of an estimated blood loss greater than 1,000 mL were reduced in the postprotocol group (OR, 0.64; 95% CI, 0.50 to 0.84; P = 0.001). CONCLUSIONS: Patients in the modified rule of threes oxytocin protocol group were more likely to receive a secondary uterotonic than those in the preprotocol group. Estimated blood loss and transfusion outcomes were similar.
RéSUMé: OBJECTIF: Les schémas thérapeutiques d'ocytocine basés sur un protocole peuvent réduire l'administration d'ocytocine par rapport à une perfusion continue en débit libre hors protocole. Notre objectif était de comparer l'utilisation secondaires d'agents utérotoniques entre un protocole modifié d'ocytocine en « règle de trois ¼ et une perfusion continue d'ocytocine à débit libre après un accouchement par césarienne. MéTHODE: Nous avons mené une étude rétrospective avant-après pour comparer les personnes ayant bénéficié d'une césarienne entre le 1er janvier 2010 et le 31 décembre 2013 (pré-protocole) avec les personnes ayant subi une césarienne entre le 1er janvier 2015 et le 31 août 2017 (post-protocole). Le groupe pré-protocole a reçu une administration d'ocytocine en débit libre et le groupe post-protocole a reçu de l'ocytocine selon un algorithme de règle de trois modifié. Le critère d'évaluation principal était l'utilisation secondaire d'agents utérotoniques et les critères d'évaluation secondaires incluaient la transfusion sanguine, un indice d'hémoglobine < 8 g·dL1 et les pertes de sang estimées. RéSULTATS: Au total, 4010 accouchements par césarienne ont été réalisés chez 3637 patient·es (2262 pré-protocole et 1748 post-protocole). Les chances de recevoir des médicaments utérotoniques secondaires étaient plus élevées dans le groupe post-protocole (rapport de cotes [RC], 1,33; intervalle de confiance [IC] à 95 %, 1,04 à 1,70; P = 0,02). Les patient·es du groupe post-protocole étaient moins susceptibles de recevoir une transfusion sanguine. Néanmoins, les deux groupes étaient similaires en ce qui touchait au critère d'évaluation composite de transfusion ou d'hémoglobine < 8 g·dL1 (RC, 0,86; IC 95, 0,66 à 1,11; P = 0,25). Les risques d'une perte de sang estimée supérieure à 1000 mL ont été réduits dans le groupe post-protocole (RC, 0,64; IC 95 %, 0,50 à 0,84; P = 0,001). CONCLUSION: Les patient·es du groupe du protocole d'ocytocine en règle de trois modifiée étaient plus susceptibles de recevoir un utérotonique secondaire que les personnes du groupe pré-protocole. Les pertes sanguines estimées et les résultats transfusionnels étaient similaires.

Maternal morbidity and mortality as a result of cardiac disease is increasing in the United States. Safe management of pregnancy in women with heart disease requires appropriate anesthetic, cardiac, and obstetric care. The anesthesiologist should risk stratify pregnant patients based upon cardiac disease etiology and severity in order to determine the appropriate type of hospital and location within the hospital for delivery and anesthetic management. Increased intrapartum hemodynamic monitoring may be necessary and neuraxial analgesia and anesthesia is typically appropriate. The anesthesiologist should anticipate obstetric and cardiac emergencies such as emergency cesarean delivery, postpartum hemorrhage, and peripartum arrhythmias. This clinical review answers practical questions for the obstetric anesthesiologist and the nonsubspecialist anesthesiologist who regularly practices obstetric anesthesiology.

Hereditary angioedema (HAE) is a disease manifested by repeated episodes of localized submucosal or subcutaneous edematous episodes, potentially triggered by emotional stress, mechanical trauma, or intake of estrogens. We present our experience managing two parturients with HAE. Multidisciplinary care is essential for planning and executing the specialized care of these patients, and management included extensive planning among obstetric, anesthesiology, and allergy and immunology teams. Pregnancy has been shown to have a variable effect on triggering HAE episodes. First-line treatment includes C1 esterase inhibitor concentrate, which can also be used for prophylaxis in high-risk patients. Neuraxial analgesia is recommended to avoid general anesthesia and was established early in both individuals. Vaginal delivery was well tolerated without need for emergent treatment for angioedema symptoms.

Maternal-fetal surgery is a rapidly evolving specialty, and significant progress has been made over the last 3 decades. A wide range of maternal-fetal interventions are being performed at different stages of pregnancy across multiple fetal therapy centers worldwide, and the anesthetic technique has evolved over the years. The American Society of Anesthesiologists (ASA) recognizes the important role of the anesthesiologist in the multidisciplinary approach to these maternal-fetal interventions and convened a collaborative workgroup with representatives from the ASA Committees of Obstetric and Pediatric Anesthesia and the Board of Directors of the North American Fetal Therapy Network. This consensus statement describes the comprehensive preoperative evaluation, intraoperative anesthetic management, and postoperative care for the different types of maternal-fetal interventions.

INTRODUCTION: In utero interventions are performed in fetuses with "isolated" major congenital anomalies to improve neonatal outcomes and quality of life. Sequential in utero interventions to treat 2 anomalies in 1 fetus have not yet been described. CASE PRESENTATION: Here, we report a fetus with a large left-sided intralobar bronchopulmonary sequestration (BPS) causing mediastinal shift, a small extralobar BPS, and concomitant severe left-sided congenital diaphragmatic hernia (CDH). At 26-week gestation, the BPS was noted to be increasing in size with a significant reduction in right lung volume and progression to fetal hydrops. The fetus underwent ultrasound-guided ablation of the BPS feeding vessel leading to complete tumor regression. However, lung development remained poor (O/E-LHR: 0.22) due to the left-sided CDH, prompting fetal endoscopic tracheal occlusion therapy at 28-week gestation to allow increased lung growth. After vaginal delivery, the newborn underwent diaphragmatic repair with resection of the extralobar sequestration. He was discharged home with tracheostomy on room air at 9 months. DISCUSSION/CONCLUSION: Sequential in utero interventions to treat 2 severe major anomalies in the same fetus have not been previously described. This approach may be a useful alternative in select cases with otherwise high morbidity/mortality. Further studies are required to confirm our hypothesis.

BACKGROUND: Intrathecal opioids are routinely administered during spinal anesthesia for postcesarean analgesia. The effectiveness of intrathecal morphine for postcesarean analgesia is well established, and the use of intrathecal hydromorphone is growing. No prospective studies have compared the effectiveness of equipotent doses of intrathecal morphine versus intrathecal hydromorphone as part of a multimodal analgesic regimen for postcesarean analgesia. The authors hypothesized that intrathecal morphine would result in superior analgesia compared with intrathecal hydromorphone 24 h after delivery. METHODS: In this single-center, double-blinded, randomized trial, 138 parturients undergoing scheduled cesarean delivery were randomized to receive 150 µg of intrathecal morphine or 75 µg of intrathecal hydromorphone as part of a primary spinal anesthetic and multimodal analgesic regimen; 134 parturients were included in the analysis. The primary outcome was the numerical rating scale score for pain with movement 24 h after delivery. Static and dynamic pain scores, nausea, pruritus, degree of sedation, and patient satisfaction were assessed every 6 h for 36 h postpartum. Total opioid consumption was recorded. RESULTS: There was no significant difference in pain scores with movement at 24 h (intrathecal hydromorphone median [25th, 75th] 4 [3, 5] and intrathecal morphine 3 [2, 4.5]) or at any time point (estimated difference, 0.5; 95% CI, 0 to 1; P = 0.139). Opioid received in the first 24 h did not differ between groups (median [25th, 75th] oral morphine milligram equivalents for intrathecal hydromorphone 30 [7.5, 45.06] vs. intrathecal morphine 22.5 [14.0, 37.5], P = 0.769). From Kaplan-Meier analysis, the median time to first opioid request was 5.4 h for hydromorphone and 12.1 h for morphine (log-rank test P = 0.200). CONCLUSIONS: Although the hypothesis was that intrathecal morphine would provide superior analgesia to intrathecal hydromorphone, the results did not confirm this. At the doses studied, both intrathecal morphine and intrathecal hydromorphone provide effective postcesarean analgesia when combined with a multimodal analgesia regimen.

Supraventricular tachycardia is a common arrhythmia in pregnancy. During labor and delivery, neuraxial analgesia is important to prevent arrhythmia recurrence. We present the case of a 27-year-old gravida 2 para 1 woman at 35 weeks' gestation presenting with supraventricular tachycardia that converted to normal sinus rhythm with adenosine. To prevent recurrence of the arrhythmia, an early epidural was provided during labor to minimize catecholamine release.

Women receiving an epidural for labor analgesia are at increased risk for intrapartum fever. This relationship has been supported by observational, before and after, and randomized controlled trials. The etiology is not well understood but is likely a result of noninfectious inflammation as studies have found women with fever have higher levels of inflammatory markers. Maternal pyrexia may change obstetric management and women are more likely to receive antibiotics or undergo cesarean delivery. Maternal pyrexia is associated with adverse neonatal outcomes. With these consequences, understanding and preventing maternal fever is imperative.

Every year the Board of Directors of the Society for Obstetric Anesthesia and Perinatology selects an individual to review the literature pertinent to obstetric anesthesiology published the previous calendar year. This individual selects the most notable contributions, creates a syllabus of the articles, and then presents his/her overview in an annual lecture named in honor of the late Gerard W. Ostheimer, a pioneering obstetric anesthesiologist from the Brigham and Women's Hospital. This article reviews the literature published in 2014 focusing on the themes of labor analgesia and cesarean delivery. Its contents were presented as the Gerard W. Ostheimer Lecture at the 47th Annual Meeting of the Society for Obstetric Anesthesia and Perinatology, May 16, 2015, in Colorado Springs, Colorado. The syllabus is available as Supplemental Digital Content (http://links.lww.com/AA/B397).

BACKGROUND: Intrathecal (IT) morphine is considered the "gold standard" for analgesia after cesarean delivery under spinal anesthesia, most commonly administered at a dose of 100 to 200 µg. There is less experience with IT hydromorphone for postcesarean analgesia and limited information on its optimal analgesic dose. We conducted this study to determine the effective analgesic dose for 90% patients (ED90) of IT hydromorphone that provides effective analgesia for women undergoing elective cesarean delivery and its potency ratio to IT morphine. METHODS: In this dose-finding trial, 80 patients received spinal anesthesia for cesarean delivery. Participants were randomized to receive IT morphine or IT hydromorphone at a dose determined using up-down sequential allocation with a biased-coin design to determine ED90. All patients received standardized multimodal analgesia postoperatively in addition to IT opioid. An effective dose was defined as a numeric response score for pain of ≤3 (scale 0-10) 12 hours after spinal injection. RESULTS: The ED90 was 75 µg (95% confidence interval [CI], 46-93 µg) for IT hydromorphone and 150 µg (95% CI, 145-185 µg) for IT morphine. At these doses, the 95% CI for the percentage of patients with effective analgesia (numeric rating scale ≤3) was 64% to 100% for hydromorphone and 68% to 100% for morphine. Exploratory findings showed that the incidence of nausea and pruritus was not different among the most commonly used doses of IT hydromorphone (P = 0.44 and P = 0.74) or IT morphine (P = 0.67 and P = 0.38, respectively). When administering IT opioids at ED90 doses or higher, 100% (21/21) of IT hydromorphone and 95% (37/39) of IT morphine patients were satisfied with their analgesia. CONCLUSIONS: The ratio of IT morphine to IT hydromorphone for effective postcesarean analgesia is 2:1. Patient satisfaction was high with both medications.

Although perimortem delivery has been recorded in the medical literature for millennia, the procedural intent has evolved to the current fetocentric approach, predicating timing of delivery following maternal cardiopulmonary arrest to optimize neonatal outcome. We suggest a call to action to reinforce the concept that if the uterus is palpable at or above the umbilicus, preparations for delivery should be made simultaneous with initiation of maternal resuscitative efforts; if maternal condition is not rapidly reversible, hysterotomy with delivery should be performed regardless of fetal viability or elapsed time since arrest. Cognizant of the difficulty in determining precise timing of arrest in clinical practice, if fetal status is already compromised further delay while attempting to assess fetal heart rate, locating optimal surgical equipment, or transporting to an operating room will result in unnecessary worsening of both maternal and fetal condition. Even if intrauterine demise has already occurred, maternal resuscitative efforts will typically be markedly improved following delivery with uterine decompression. Consequently we suggest that perimortem cesarean delivery be renamed "resuscitative hysterotomy" to reflect the mutual optimization of resuscitation efforts that would potentially provide earlier and more substantial benefit to both mother and baby.

STUDY OBJECTIVE: Nitrous oxide affects memory and recall. We aimed to determine if using nitrous oxide during labor affected patients' ability to learn and recall the risks and benefits of neuraxial analgesia. DESIGN: Single-center, prospective cohort study. SETTING: Labor and delivery unit in a large academic medical center. PATIENTS: Nulliparous patients with spontaneous or planned induction of labor. INTERVENTIONS: Parturients chose whether to use nitrous oxide during labor. At the discussion for epidural consent, 4 risks were described: headache, infection, nerve damage, bleeding. MEASUREMENTS: Labor pain score, time from nitrous oxide discontinuation, and cervical dilation were documented at the discussion of epidural risks. Patients were assessed for unprompted recall and prompted recall of epidural risks on postpartum day 1 and unprompted recall at postpartum week 6. The number and proportion of patients who indicated each true risk (unprompted and prompted recall) or distractor (prompted recall only) were summarized by treatment group and results compared using Pearson χ2 tests. MAIN RESULTS: Of the 403 enrolled patients, 294 (73%) did not use nitrous oxide, and 109 (27%) did. The 2 groups were similar except women who used nitrous oxide were more likely to be cared for by midwives and had higher pain scores at their epidural request. Scores for unprompted or prompted recall of epidural risks were not different between women who received or did not receive nitrous oxide. All 4 risks were recalled unprompted by only 3% in the nitrous oxide group and by 6% in the group not receiving nitrous oxide (P = .18). CONCLUSIONS: The use of nitrous oxide for labor analgesia does not adversely influence a parturient's ability to recall the risks of epidural placement. Patients who receive nitrous oxide for labor analgesia should be considered eligible to provide consent for subsequent procedures.
RESUMEN
BACKGROUND: Limited data exist to characterize maternal and fetal outcomes during pregnancy using cardiopulmonary bypass. METHODS: Retrospective review was performed of all pregnant individuals who underwent cardiac surgery utilizing cardiopulmonary bypass at a single center from 1978 to 2023. Descriptive statistical analysis was performed, with a median reported for continuous variables and incidence for dichotomous variables. RESULTS: Twenty-nine pregnant patients with a median age of 28 (25, 32) years underwent cardiac surgery using cardiopulmonary bypass at a median gestation of 25 (16, 29) weeks. Surgery was performed in the 1st trimester for 3 (10%), 2nd trimester for 16 (55%), and 3rd trimester for 10 (35%) patients; 15 (52%) were emergent and 14 (48%) were urgent procedures. There was one (3%) maternal death two days after mechanical aortic valve thrombectomy and 5 (17%) fetal losses. Fourteen patients who underwent cardiac surgery using cardiopulmonary bypass with continuing pregnancy experienced a 29% fetal mortality rate, and 7 patients underwent delivery prior to surgery and experienced 14% fetal mortality. Among cases of fetal loss, surgery was performed at a median of 25 (21, 26) weeks compared to a median of 23 (20, 29) weeks in cases without fetal loss (p=0.55). CONCLUSIONS: Cardiac surgery during pregnancy was associated with low maternal mortality but significant fetal mortality. This single-institution series supports consideration of cesarean delivery prior to cardiopulmonary bypass procedures if the fetus is of a viable gestational age to minimize mortality.
RESUMEN
The prevalence of cardiac disease-related maternal morbidity and mortality is on the rise in the United States. To ensure safe management of pregnancy in patients with cardiovascular disease, pre-delivery evaluation by a multidisciplinary Pregnancy Heart Team should occur. Appropriate anesthetic, cardiac, and obstetric care are essential. Risk stratification tools evaluate the etiology and severity of cardiovascular disease to determine the appropriate hospital type and location for delivery and anesthetic management. Intrapartum hemodynamic monitoring may need to be intensified, and neuraxial analgesia and anesthesia are generally appropriate. The anesthesiologist must be prepared for obstetric and cardiac emergencies.

Ebstein anomaly is a rare congenital cardiac condition associated with displacement and incompetence of the tricuspid valve. Peripartum anesthetic management can be particularly challenging since these patients are at high risk of cardiac failure and tachyarrhythmias. Risk stratification is important since it helps to identify high-risk patients who should deliver at a tertiary care center where a multidisciplinary team (obstetrics, cardiology, anesthesiology, and neonatology) is immediately available. We describe the peripartum anesthetic management of 9 patients with Ebstein anomaly who underwent 12 deliveries at our institution. All patients tolerated neuraxial anesthesia and analgesia well. No maternal or fetal deaths occurred.
RESUMEN
Although some women want to experience childbirth without medications, most women in the United States labor with an epidural or spinal analgesic. Epidurals provide relatively consistent pain relief, are long-lasting, can be titrated according to the analgesic needs of the mother, and can be bolused for procedures such as forceps, vacuum, or cesarean delivery. But they can have undesirable side effects including lower-extremity motor block, hypotension, urinary retention, and pruritus, and they may increase the risk for a slightly prolonged labor, a forceps or vacuum delivery, and fever during labor. This article describes the current thinking regarding labor analgesia and how anesthesiologists and obstetricians can help women have a birth experience that is both safe and satisfying.
