RESUMEN
Importance: Dural-puncture epidural (DPE) and standard epidural are common modes of neuraxial labor analgesia. Little is known about conversion of DPE-initiated labor analgesia to surgical anesthesia for cesarean delivery. Objective: To determine whether DPE provides a faster onset and better-quality block compared with the standard epidural technique for cesarean delivery. Design, Setting, and Participants: This double-blind, randomized clinical trial was conducted between April 2019 and October 2022 at a tertiary care university hospital (University of Arkansas for Medical Sciences). Participants included women aged 18 years and older undergoing scheduled cesarean delivery with a singleton pregnancy. Interventions: Participants were randomized to receive DPE or standard epidural in the labor and delivery room. A T10 sensory block was achieved and maintained using a low concentration of bupivacaine with fentanyl through the epidural catheter until the time of surgery. Epidural extension anesthesia was initiated in the operating room. Main Outcomes and Measures: The primary outcome was the time taken from chloroprocaine administration to surgical anesthesia (T6 sensory block). The secondary outcome was the quality of epidural anesthesia, as defined by a composite of the following factors: (1) failure to achieve a T10 bilateral block preoperatively in the delivery room, (2) failure to achieve a surgical block at T6 within 15 minutes of chloroprocaine administration, (3) requirement for intraoperative analgesia, (4) repeat neuraxial procedure, and (5) conversion to general anesthesia. Results: Among 140 women (mean [SD] age, 30.1 [5.2] years), 70 were randomized to the DPE group, and 70 were randomized to the standard epidural group. The DPE group had a faster onset time to surgical anesthesia compared with the standard epidural group (median [IQR], 422 [290-546] seconds vs 655 [437-926] seconds; median [IQR] difference, 233 [104-369] seconds). The composite rates of lower quality anesthesia were 15.7% (11 of 70 women) in the DPE group and 36.3% (24 of 66 women) in the standard epidural group (odds ratio, 0.33; 95% CI, 0.14-0.74; P = .007). Conclusions and Relevance: Anesthesia initiated following a DPE technique resulted in faster onset and improved block quality during epidural extension compared with initiation with a standard epidural technique. Further studies are needed to confirm these findings in the setting of intrapartum cesarean delivery. Trial Registration: ClinicalTrials.gov Identifier: NCT03915574.

The rising in placenta accreta spectrum (PAS) incidence, highlights the need for critical care allotment for these patients. Due to risk for hemorrhage and possible hemorrhagic shock requiring blood product transfusion, hemodynamic instability and risk of end-organ damage, having an intensive care unit (ICU) with surgical expertise (surgical ICU or equivalent based on institutional resources) is highly recommended. Intensive care units physicians and nurses should be familiarized with intraoperative anesthetic and surgical techniques as well as obstetrics physiologic changes to provide postpartum management of PAS. Validated tools such of bedside point of care ultrasound and viscoelastic tests such as thromboelastogram/rotational thromboelastometry (TEG/ROTEM) are clinically useful in the assessment of hemodynamic status (shock diagnosis, assessment of both fluid responsiveness and tolerance) and transfusion guidance (in patients requiring massive transfusion as opposed to tranditional hemostatic resuscitation) respectively. The future of PAS management lies in the collaborative and multidisciplinary environment. We recommend that women with high suspicion or a confirmed PAS should have a preoperative plan in place and be managed in a tertiary center who is experienced in managing surgically complex cases. KEY POINTS: · The rising in placenta accreta spectrum incidence highlights the need for critical care expertise.. · Emerging tools such as point-of-care ultrasound and thromboelastography/rotational thromboelastometry represent new avenues for real time optimization of hemodynamic and hematological care of patients with PAS.. · Patients with PAS should be referred to a tertiary center having an intensive care unit (ICU) with surgical expertise (or equivalent based on institutional resources)..

Enhanced recovery after cesarean delivery is a protocolized approach to perioperative care, with the aim to optimize maternal recovery after surgery. It is associated with improved maternal and neonatal outcomes, including decreased length of hospital stay, opioid consumption, pain scores, complications, increased maternal satisfaction, and increased breastfeeding success. However, the pace and enthusiasm of adoption of enhanced recovery after cesarean delivery internationally has not yet been matched with high-quality evidence demonstrating its benefit, and current studies provide low- to very low-quality evidence in support of enhanced recovery after cesarean delivery. This article provides a summary of current measures of enhanced recovery after cesarean delivery success, and optimal measures of inpatient and outpatient postpartum recovery. We summarize outcomes from 22 published enhanced recovery after cesarean delivery implementation studies and 2 meta-analyses. A variety of disparate metrics have been used to measure enhanced recovery after cesarean delivery success, including process measures (length of hospital stay, bundle compliance, preoperative fasting time, time to first mobilization, time to urinary catheter removal), maternal outcomes (patient-reported outcome measures, complications, opioid consumption, satisfaction), neonatal outcomes (breastfeeding success, Apgar scores, maternal-neonatal bonding), cost savings, and complication rates (maternal readmission rate, urinary recatheterization rate, neonatal readmission rate). A core outcome set for use in enhanced recovery after cesarean delivery studies has been developed through Delphi consensus, involving stakeholders including obstetricians, anesthesiologists, patients, and a midwife. Fifteen measures covering key aspects of enhanced recovery after cesarean delivery adoption are recommended for use in future enhanced recovery after cesarean delivery implementation studies. The use of these outcome measures could improve the quality of evidence surrounding enhanced recovery after cesarean delivery. Using evidence-based evaluation guidelines developed by the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) group, the Obstetric Quality of Recovery score (ObsQoR) was identified as the best patient-reported outcome measure for inpatient postpartum recovery. Advances in our understanding of postpartum recovery as a multidimensional and dynamic construct have opened new avenues for the identification of optimum patient-reported outcome measures in this context. The use of standardized measures such as these will facilitate pooling of data in future studies and improve overall levels of evidence surrounding enhanced recovery after cesarean delivery. Larger studies with optimal study designs, using recommended outcomes including patient-reported outcome measures, will reduce variation and improve data quality to help guide future recommendations.
RESUMEN
BACKGROUND: Chloroprocaine is a short-acting local anesthetic that has been used for spinal anesthesia in outpatient surgery. There is limited experience with spinal chloroprocaine for prophylactic cervical cerclage placement. We sought to determine the effective dose of intrathecal chloroprocaine for 90% of patients (ED90) undergoing prophylactic cervical cerclage placement. We hypothesized that the ED90 of intrathecal chloroprocaine when combined with 10-ug fentanyl would be between 33 and 54 mg. METHODS: In this prospective 2-center double-blinded study, we enrolled women undergoing prophylactic cervical cerclage placement under combined spinal-epidural anesthesia. A predetermined dose of intrathecal 3% chloroprocaine with fentanyl 10 ug was administered. The initial dose was 45-mg intrathecal chloroprocaine. Subsequent dose adjustments were determined based on the response of the previous subject using an up-down sequential allocation with a biased-coin design. A dose was considered effective if at least a T12 block was achieved, and there was no requirement for epidural activation or intraoperative analgesic supplementation during the procedure. The primary outcome was the ED90 of intrathecal chloroprocaine with fentanyl 10 ug. Secondary outcomes included duration of surgery, anesthetic side effects, time to resolution of motor and sensory block, time to achieve recovery room discharge criteria, and patient satisfaction with anesthetic care. Isotonic regression was used to estimate the ED90. RESULTS: Forty-seven patients were enrolled into the study. Two patients were excluded (1 protocol violation and 1 failed block). In total, 45 patients completed the study. The estimated ED90 (95% confidence interval) for intrathecal chloroprocaine combined with fentanyl 10 ug was 49.5 mg (45.0-50.1 mg). The median (interquartile range [IQR]) duration of surgery was 15 (10-24) minutes. Resolution of the motor (Bromage 0) and sensory block took a median time of 60 (45-90) minutes and 90 (75-105) minutes, respectively. The median time to achieve recovery room discharge criteria was 150 (139-186) minutes. Satisfaction with anesthetic management was high in all patients. There were no reports of postdural puncture headache or transient neurological symptoms postoperatively. CONCLUSIONS: The ED90 of intrathecal chloroprocaine combined with fentanyl 10 ug was 49.5 mg. Intrathecal chloroprocaine was associated with rapid block recovery and high patient satisfaction, which makes it well suited for outpatient obstetric procedures.

PURPOSE: We conducted an updated systematic review and meta-analysis on maternal outcomes associated with uterine exteriorization compared with in situ repair in women undergoing Cesarean delivery. METHODS: We searched for randomized controlled trials comparing uterine exteriorization with in situ repair during Cesarean delivery. Primary outcomes were intraoperative nausea and vomiting (IONV) and perioperative decrease in hemoglobin concentration. Secondary outcomes were postoperative nausea and vomiting (PONV), estimated blood loss, fever, endometritis, wound infection, intraoperative and postoperative pain, postoperative analgesic use, duration of surgery and hospital stay, and time to return of bowel function. RESULTS: Twenty studies with 20,909 parturients were included. Exteriorization was associated with higher risk of IONV (odds ratio [OR], 2.09; 95% confidence interval [CI], 1.66 to 2.63; I2 = 0%), with no difference in perioperative hemoglobin concentration decrease (mean difference, - 0.06 g·dL-1; 95% CI, - 0.20 to 0.08; I2 = 97%) compared with in situ repair. There were no significant differences in estimated blood loss, transfusion requirement, PONV, duration of surgery, duration of hospital stay, time to return of bowel function, fever, endometritis, or wound infection. Postoperative pain (incidence of pain graded > 5/10) at six hours (OR, 1.64; 95% CI, 1.31 to 2.03; I2 = 0%) was higher with exteriorization, but there was no difference in need for rescue analgesia (OR, 2.48; 95% CI, 0.89 to 6.90; I2 = 94%) or pain scores at 24 hr compared with in situ repair. CONCLUSIONS: In this updated systematic review and meta-analysis, uterine exteriorization was associated with an increased risk of IONV but no significant change in perioperative hemoglobin decrease compared with in situ repair.

RéSUMé: OBJECTIF: Nous avons réalisé une mise à jour d'une revue systématique et une méta-analyse portant sur les issues maternelles associées à l'extériorisation de l'utérus par rapport à une réparation in situ chez les femmes accouchant par césarienne. MéTHODE: Nous avons recherché des études randomisées contrôlées comparant l'extériorisation de l'utérus à la réparation in situ pendant un accouchement par césarienne. Les critères d'évaluation principaux étaient les nausées et vomissements peropératoires (NVPerO) et la réduction périopératoire de l'hémoglobine. Les critères d'évaluation secondaires étaient les nausées et vomissements postopératoires (NVPO), la perte de sang estimée, la fièvre, l'endométrite, l'infection de la plaie, la douleur per- et postopératoire, l'utilisation d'analgésiques postopératoires, la durée de la chirurgie et du séjour à l'hôpital, et le délai jusqu'au retour du transit. RéSULTATS: Vingt études portant sur 20 909 parturientes ont été incluses. L'extériorisation était associée à un risque plus élevé de NVPerO (rapport de cotes [RC], 2,09; intervalle de confiance à 95 % [IC], 1,66 à 2,63; I2 = 0 %), sans différence dans la réduction de l'hémoglobine périopératoire (différence moyenne, − 0,06 g·dL-1; IC 95 %, − 0,20 à 0,08; I2 = 97 %) par rapport à une réparation in situ. Il n'y avait pas de différences significatives dans la perte de sang estimée, les besoins transfusionnels, les NVPO, la durée de la chirurgie, la durée du séjour à l'hôpital, le délai jusqu'au retour du transit, la fièvre, l'endométrite ou l'infection de la plaie. La douleur postopératoire (incidence de la douleur graduée > 5/10) à six heures (RC, 1,64; IC 95 %, 1,31 à 2,03; I2 = 0 %) était plus élevée avec une extériorisation, mais il n'y avait aucune différence dans les besoins d'analgésie de secours (RC, 2,48; IC 95 %, 0,89 à 6,90; I2 = 94 %) ou les scores de douleur à 24 heures par rapport à une réparation in situ. CONCLUSION: Dans cette revue systématique et méta-analyse mises à jour, l'extériorisation utérine était associée à un risque accru de NVPerO, mais à aucun changement significatif dans la réduction de l'hémoglobine périopératoire par rapport à la réparation in situ.

OBJECTIVE: To compare prophylactic and emergent resuscitative endovascular balloon occlusion of the aorta (REBOA) catheter placement in the management of placenta accreta spectrum (PAS). STUDY DESIGN: Retrospective chart review of all patients with PAS (January 2018 to January 2020) at a single tertiary center who underwent prophylactic or emergent REBOA for cesarean hysterectomy for PAS. RESULTS: A total of 16 pregnant patients with PAS underwent percutaneous REBOA placement by acute care surgeons in collaboration with a multi-disciplinary PAS team. The REBOA catheter was placed prophylactically in 11 cases and emergently in 5 cases. No complications occurred in the prophylactic placement group. In the emergent placement group, 3 of 4 surviving patients had vascular access site complications requiring intervention. CONCLUSION: A multidisciplinary approach for the management of PAS utilizing REBOA is feasible in the setting of both planned and emergent cesarean hysterectomy and can aid in the control of acute hemorrhage. The risk for vascular access site complications related to REBOA catheter placement is higher in the emergent setting compared to prophylactic placement.

BACKGROUND: This meta-analysis explores the impact of enhanced recovery after cesarean delivery (ERAC) on maternal outcomes. METHODS: We searched 4 databases (Web of Science, Embase, PubMed and CINAHL) in October 2020 without date limiters, for studies quantitatively comparing ERAC implementation to a control group. The primary outcome was length of hospital stay and secondary outcomes included time to mobilization and time to urinary catheter removal, opioid consumption, readmission rates and cost savings. Mean differences and odds ratios (MD and OR with 95% confidence intervals) were calculated. Levels of evidence were assessed using GRADE. RESULTS: Twelve studies involving 17,607 patients (9693 without ERAC and 7914 with ERAC) were included. ERAC was associated with reduced: length of hospital stay (MD -0.51 days [-0.94, -0.09]; pâ¯=â¯0.018; I2â¯=â¯99%), time to first mobilization (MD -11.05â¯h [-18.64, -3.46]; pâ¯=â¯0.004; I2â¯=â¯98%), time to urinary catheter removal (MD -13.19â¯h [-17.59, -8.79]; pâ¯<â¯0.001; I2â¯=â¯97%) and opioid consumption (MD -21.85â¯mg morphine equivalents [-33.19, -10.50]; pâ¯=â¯< 0.001; I2â¯=â¯91%), with no difference in maternal readmission rate (OR 1.23 [0.96, 1.57]; pâ¯=â¯0.10; I2â¯=â¯0%). Three studies reported cost savings associated with ERAC. The GRADE levels of evidence were rated as low or very low quality for all study outcomes. CONCLUSION: ERAC is associated with reduction in length of stay, times to first mobilization and urinary catheter removal and opioid consumption. ERAC does not significantly affect maternal hospital readmission rates following discharge. Further studies are required to determine which ERAC interventions to implement and which outcomes best determine ERAC efficacy.

PURPOSE OF REVIEW: The incidence of placenta accreta spectrum is increasing and it is a leading cause of peripartum hysterectomy and massive postpartum hemorrhage. The purpose of the present article is to provide a contemporary overview of placenta accreta spectrum pertinent to the obstetric anesthesiologist. RECENT FINDINGS: Recent changes in the terminology used to report invasive placentation were proposed to clarify diagnostic criteria and guidelines for use in clinical practice. Reduced morbidity is associated with scheduled preterm delivery in a center of excellence using a multidisciplinary team approach. Neuraxial anesthesia as a primary technique is increasingly being used despite the known risk of major bleeding. The use of viscoelastic testing and endovascular interventions may aid hemostatic resuscitation and improve outcomes. SUMMARY: Accurate diagnosis and early antenatal planning among team members are essential. Obstetric anesthesiologists should be prepared to manage a massive hemorrhage, transfusion, and associated coagulopathy. Increasingly, viscoelastic tests are being used to assess coagulation status and the ability to interpret these results is required to guide the transfusion regimen. Balloon occlusion of the abdominal aorta has been proposed as an intervention that could improve outcomes in women with placenta accreta spectrum, but high-quality safety and efficacy data are lacking.

BACKGROUND: We performed a systematic review using Consensus Based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines to identify the best available patient-reported outcome measure (PROM) of postpartum pain. METHODS: This review follows COSMIN guidelines. We searched four databases with no date limiters, for previously identified validated PROMs used to assess postpartum pain. PROMs evaluating more than one author-defined domain of postpartum pain were assessed. We sought studies evaluating psychometric properties. An overall rating was then assigned based upon COSMIN analysis, and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the level of evidence for psychometric properties of included PROMs. These assessments were used to make recommendations and identify the best PROM to assess postpartum pain. RESULTS: We identified 19 studies using seven PROMs (involving 3511 women), which evaluated postpartum pain. All included studies evaluated ≥1 psychometric property of the included PROMs. An adequate number of pain domains was assessed by the Brief Pain Inventory (BPI), Short Form-BPI (SF-BPI), and McGill Pain Questionnaire (MPQ). The SF-BPI was the only PROM to demonstrate adequate content validity and at least a low-level of evidence for sufficient internal consistency, resulting in a Class A recommendation (the best performing instrument, recommended for use). CONCLUSION: SF-BPI is the best currently available PROM to assess postpartum pain. However, it fails to assess several important domains and only just met the criteria for a Class A recommendation. Future studies are warranted to develop, evaluate, and implement a new PROM designed to specifically assess postpartum pain.

Importance: Outpatient postpartum recovery is an underexplored area of obstetrics. There is currently no consensus regarding which patient-reported outcome measure (PROM) clinicians and researchers should use to evaluate postpartum recovery. Objective: To evaluate PROMs of outpatient postpartum recovery using Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines. Evidence Review: An initial literature search performed in July 2019 identified postpartum recovery PROMs and validation studies. A secondary search in July 2020 identified additional validation studies. Both searches were performed using 4 databases (Web of Science, Embase, PubMed, and CINAHL), with no date limiters. Studies with PROMs evaluating more than 3 proposed outpatient postpartum recovery domains were considered. Studies were included if they assessed any psychometric measurement property of the included PROMs in the outpatient postpartum setting. The PROMs were assessed for the following 8 psychometric measurement properties, as defined by COSMIN: content validity, structural validity, internal consistency, cross-cultural validity and measurement invariance, reliability, measurement error, hypothesis testing, and responsiveness. Psychometric measurement properties were evaluated in each included study using the COSMIN criteria by assessing (1) the quality of the methods (very good, adequate, doubtful, inadequate, or not assessed); (2) overall rating of results (sufficient, insufficient, inconsistent, or indeterminate); (3) level of evidence assessed using the Grading of Recommendations, Assessment, Development and Evaluations assessment tool; and (4) level of recommendation, which included class A (recommended for use; showed adequate content validity with at least low-quality evidence for sufficient internal consistency), class B (not class A or class C), or class C (not recommended). Findings: In total, 15 PROMs (7 obstetric specific and 8 non-obstetric specific) were identified, evaluating outpatient postpartum recovery in 46 studies involving 19â¯165 women. The majority of psychometric measurement properties of the included PROMs were graded as having very-low-level or low-level evidence. The best-performing PROMs that received class A recommendations were the Maternal Concerns Questionnaire, the Postpartum Quality of Life tool, and the World Health Organization Quality of Life-BREF. The remainder of the evaluated PROMs had insufficient evidence to make recommendations regarding their use (and received class B recommendations). Conclusions and Relevance: This review found that the best-performing PROMs currently available to evaluate outpatient postpartum recovery were the Maternal Concerns Questionnaire, the Postpartum Quality of Life tool, and the World Health Organization Quality of Life-BREF; however, these tools all had significant limitations. This study highlights the need to focus future efforts on robustly developing and validating a new PROM that may comprehensively evaluate outpatient postpartum recovery.

BACKGROUND: For emergent intrapartum cesarean delivery (CD), the literature does not support the use of any particular local anesthetic solution to extend epidural analgesia to cesarean anesthesia. We hypothesized that 3% chloroprocaine (CP) would be noninferior to a mixture of 2% lidocaine, 150 µg of epinephrine, 2 mL of 8.4% bicarbonate, and 100 µg of fentanyl (LEBF) in terms of onset time to surgical anesthesia. METHODS: In this single-center randomized noninferiority trial, adult healthy women undergoing CD were randomly assigned to epidural anesthesia with either CP or LEBF. Sensory blockade (pinprick) to T10 was established before operating room (OR) entry for elective CD. On arrival to the OR, participants received the epidural study medications in a standardized manner to simulate the conversion of "epidural labor analgesia to surgical anesthesia." The primary outcome was the time to loss of touch sensation at the T7 level. A noninferiority margin was set at 3 minutes. The secondary outcome was the need for intraoperative analgesia supplementation. RESULTS: In total, 70 women were enrolled in the study. The mean onset time to achieve a bilateral sensory block to touch at the T7 dermatome level was 655 (standard deviation [SD] = 258) seconds for group CP and 558 (269) seconds for group LEBF, a difference in means of 97 seconds (90% confidence interval [CI], SD = -10.6 to 204; P = .10 for noninferiority). The upper limit of the 90% CI for the mean difference exceeded the prespecified 3-minute noninferiority margin. There was no meaningful difference in the requirement for intraoperative analgesia between the 2 groups. CONCLUSION: Both anesthetic solutions have a rapid onset of anesthesia when used to extend low-dose epidural sensory block to surgical anesthesia. Data from the current study provide insufficient evidence to confirm that CP is noninferior to LEBF for rapid epidural extension anesthesia for CD, and further research is required to determine noninferiority.

BACKGROUND: Few adequately validated patient-reported outcome measures are available, which can assess recovery profiles following childbirth. OBJECTIVE: We aimed to determine whether quantitative recovery (using the Obstetric Quality of Recovery-10 patient-reported outcome measure) was superior following vaginal delivery compared with cesarean delivery and evaluate validity, reliability, and responsiveness of this patient-reported outcome measure in the obstetrical setting in the United States. STUDY DESIGN: Women recruited into this single-center observational cohort study completed the Obstetric Quality of Recovery-10 and EuroQol 5-dimension 3L patient-reported outcome measures within 72 hours of childbirth. We assessed the validity with hypothesis testing and structural validity. In hypothesis testing, the primary outcome was Obstetric Quality of Recovery-10 scores after vaginal vs cesarean delivery. Secondary outcomes were differences in Obstetric Quality of Recovery-10 scores for vaginal delivery following induction of labor vs spontaneous labor and scheduled vs unplanned cesarean delivery, correlation with clinical parameters (American Society of Anesthesiologists classification grade, body mass index, length of hospital stay, estimated blood loss, transfusion requirement, antiemetic use, and neonatal intensive care unit admission), and qualitative ranking of Obstetric Quality of Recovery-10 items for each delivery mode. Structural validity was assessed by determining the correlation of the Obstetric Quality of Recovery-10 scores with the EuroQol 5-dimension 3L and global health visual analog scale scores. Reliability was assessed using Cronbach alpha and inter-item correlation of Obstetric Quality of Recovery-10 items. Responsiveness was assessed by evaluating the change in Obstetric Quality of Recovery-10 scores over the 72-hour postpartum period. RESULTS: Data from 215 women were analyzed. In hypothesis testing, the median (interquartile range) Obstetric Quality of Recovery-10 scores were higher following vaginal delivery than cesarean delivery (86 [77-94] vs 77 [64-86], respectively; P<.001). Multivariate model demonstrated that Obstetric Quality of Recovery-10 scores were significantly lower after cesarean delivery when adjusting for American Society of Anesthesiologists classification grade, age, body mass index, and ethnicity (R=-8.97; P<.001). Obstetric Quality of Recovery-10 scores were similar between induction of labor and spontaneous labor, and scheduled cesarean delivery and unplanned cesarean delivery. Obstetric Quality of Recovery-10 was correlated with length of hospital stay (R=-0.248; P<.001), estimated blood loss (R=-0.3429; P<.001), transfusion requirement (R=-0.140; P=.041), and antiemetic use (R=-0.280; P<.001). The highest ranked Obstetric Quality of Recovery-10 items were ability to hold baby, feeling in control, and ability to look after personal hygiene. The lowest ranked items were pain and shivering. In structural validity, correlation of Obstetric Quality of Recovery-10 score was moderate with the global health visual analog scale (r=0.511) and EuroQol 5-dimension 3L scores (r=-0.509). In reliability, Cronbach alpha was 0.72 and more than 80% of individual items correlated. In responsiveness, Obstetric Quality of Recovery-10 scores did not change significantly over the study period. CONCLUSION: Quantitative inpatient recovery following vaginal delivery is superior to cesarean delivery. The Obstetric Quality of Recovery-10 appears to be a valid and reliable patient-reported outcome measure following these delivery modes. Further studies are needed to determine how to improve recovery domains identified in this study, to evaluate Obstetric Quality of Recovery-10 in different languages and determine whether these domains impact outcomes beyond hospitalization.

Importance: Despite the global delivery rate being approximately 259 deliveries per minute in 2018, postpartum recovery remains poorly defined. Objectives: To identify validated patient-reported outcome measures (PROMs) used to assess outpatient and inpatient postpartum recovery, evaluate frequency of PROM use, report the proportion of identified PROMs used within each recovery domain, report the number of published studies within each recovery domain, summarize descriptive data (country of origin, year of study, and journal specialty) for published studies using PROMs to evaluate postpartum recovery, and report PROMs used to evaluate global postpartum recovery. Evidence Review: This study followed PRISMA-ScR guidelines. A literature search of 4 databases (MEDLINE through PubMed, Embase, Web of Science, and CINAHL) was performed on July 1, 2019, to identify PROMs used to evaluate 12 author-defined domains of postpartum recovery. All psychometrically evaluated PROMs used to evaluate inpatient or outpatient postpartum recovery after all delivery modes were included. Findings: From 8008 screened titles and abstracts, 573 studies (515 outpatient and 58 inpatient) were identified in this review. A total of 201 PROMs were used to assess recovery for outpatient studies and 73 PROMs were used to assess recovery for inpatient studies. The top 5 domains (with highest to lowest numbers of PROMs) used to assess outpatient recovery were psychosocial distress (77 PROMs), surgical complications (26 PROMs), psychosocial support (27 PROMs), motherhood experience (16 PROMs), and sexual function (13 PROMs). Among inpatient studies, the top 5 domains were psychosocial distress (32 PROMs), motherhood experience (7 PROMs), psychosocial support (5 PROMs), fatigue (5 PROMs), and cognition (3 PROMs). The 3 most frequently used PROMs were the Edinburgh Postnatal Depression Scale (267 studies), Short-Form 36 Health Questionnaire (global recovery assessment; 40 studies), and Female Sexual Function Index (35 studies). A total of 24 global recovery PROMs were identified among all included studies. Most studies were undertaken in the United States within the last decade and were published in psychiatry and obstetrics and gynecology journals. Conclusions and Relevance: Most PROMs identified in this review evaluated a single domain of recovery. Future research should focus on determining the psychometric properties of individual and global recovery PROMs identified in this review to provide recommendations regarding optimum measures of postpartum recovery.

With increasing numbers of coronavirus disease 2019 (COVID-19) cases due to efficient human-to-human transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the United States, preparation for the unpredictable setting of labor and delivery is paramount. The priorities are 2-fold in the management of obstetric patients with COVID-19 infection or persons under investigation (PUI): (1) caring for the range of asymptomatic to critically ill pregnant and postpartum women; (2) protecting health care workers and beyond from exposure during the delivery hospitalization (health care providers, personnel, family members). The goal of this review is to provide evidence-based recommendations or, when evidence is limited, expert opinion for anesthesiologists caring for pregnant women during the COVID-19 pandemic with a focus on preparedness and best clinical obstetric anesthesia practice.

The prevalence of neuraxial opioid-induced clinically significant respiratory depression (CSRD) after cesarean delivery is unknown. We sought to review reported cases of author-reported respiratory depression (ARD) to calculate CSRD prevalence. A 6-database literature search was performed to identify ARD secondary to neuraxial morphine or diamorphine, in parturients undergoing cesarean delivery. "Highest" (definite and probable/possible) and "lowest" (definite) prevalences of CSRD were calculated. Secondary outcomes included: (1) prevalence of CSRD associated with contemporary doses of neuraxial opioid, (2) prevalence of ARD as defined by each study's own criteria, (3) case reports of ARD, and (4) reports of ARD reported by the Anesthesia Closed Claims Project database between 1990 and 2016. We identified 78 articles with 18,455 parturients receiving neuraxial morphine or diamorphine for cesarean delivery. The highest and lowest prevalences of CSRD with all doses of neuraxial opioids were 8.67 per 10,000 (95% CI, 4.20-15.16) and 5.96 per 10,000 (95% CI, 2.23-11.28), respectively. The highest and lowest prevalences of CSRD with the use of clinically relevant doses of neuraxial morphine ranged between 1.63 per 10,000 (95% CI, 0.62-8.77) and 1.08 per 10,000 (95% CI, 0.24-7.22), respectively. The prevalence of ARD as defined by each individual paper was 61 per 10,000 (95% CI, 51-74). One published case report of ARD met our inclusion criteria, and there were no cases of ARD from the Closed Claims database analysis. These results indicate that the prevalence of CSRD due to neuraxial morphine or diamorphine in the obstetric population is low.

BACKGROUND: Discharge diagnoses are used to track national trends and patterns of maternal morbidity. There are few data regarding the validity of the International Classification of Diseases (ICD) codes used for this purpose. The goal of our study was to try to better understand the validity of administrative data being used to monitor and assess trends in morbidity. METHODS: Hospital stay billing records were queried to identify all delivery admissions at the Massachusetts General Hospital for the time period 2001 to 2011 and the University of Michigan Health System for the time period 2005 to 2011. From this, we identified patients with ICD-9-Clinical Modification (CM) diagnosis and procedure codes indicative of severe maternal morbidity. Each patient was classified with 1 of 18 different medical/obstetric categories (conditions or procedures) based on the ICD-9-CM code that was recorded. Within each category, 20 patients from each institution were selected at random, and the corresponding medical charts were reviewed to determine whether the ICD-9-CM code was assigned correctly. The percentage of correct codes for each of 18 preselected clinical categories was calculated yielding a positive predictive value (PPV) and 99% confidence interval (CI). RESULTS: The overall number of correctly assigned ICD-9-CM codes, or PPV, was 218 of 255 (86%; CI, 79%-90%) and 154 of 188 (82%; CI, 74%-88%) at Massachusetts General Hospital and University of Michigan Health System, respectively (combined PPV, 372/443 [84%; CI, 79-88%]). Codes within 4 categories (Hysterectomy, Pulmonary edema, Disorders of fluid, electrolyte and acid-base balance, and Sepsis) had a 99% lower confidence limit ≥75%. Codes within 8 additional categories demonstrated a 99% lower confidence limit between 74% and 50% (Acute respiratory distress, Ventilation, Other complications of obstetric surgery, Disorders of coagulation, Cardiomonitoring, Acute renal failure, Thromboembolism, and Shock). Codes within 6 clinical categories demonstrated a 99% lower confidence limit <50% (Puerperal cerebrovascular disorders, Conversion of cardiac rhythm, Acute heart failure [includes arrest and fibrillation], Eclampsia, Neurotrauma, and Severe anesthesia complications). CONCLUSIONS: ICD-9-CM codes capturing severe maternal morbidity during delivery hospitalization demonstrate a range of PPVs. The PPV was high when objective supportive evidence, such as laboratory values or procedure documentation supported the ICD-9-CM code. The PPV was low when greater judgment, interpretation, and synthesis of the clinical data (signs and symptoms) was required to support a code, such as with the category Severe anesthesia complications. As a result, these codes should be used for administrative research with more caution compared with codes primarily defined by objective data.

Rapid sequence induction of general anaesthesia (GA) is the fastest anaesthetic technique in a category-1 caesarean section (C1CS) for foetal distress. Recently rapid sequence spinal anaesthesia (RSS) has been explored as a technique to avoid the potential risks of GA in such cases. Out of hours, trainee anaesthetists are often required to provide anaesthesia for these emergencies. We surveyed their practices when performing a RSS. The aim of a RSS is to rapidly and safely achieve anaesthesia for C1CS, while optimising foetal oxygenation and preparing for possible GA. It requires anaesthetic skill, team work and communication. Many trainees understood the principles of the RSS, however, a significant number did not. Practice varied widely and no trainee had received any formal RSS training. Training for junior anaesthetists and those working in obstetric theatres, in the conduct of the RSS is crucial, to ensure safe practice, avoid delays in delivery and safely avoid the risks associated with GA in the C1CS.
