Transfusion Requirements with Hybrid Management of Placenta Accreta Spectrum Incorporating Targeted Embolization and a Selective Use of Delayed Hysterectomy.

OBJECTIVE: This study compares the number of units of red blood cells (RBCs) transfused in patients with placenta accreta spectrum (PAS) treated with or without a multidisciplinary algorithm that includes placental uterine arterial embolization (P-UAE) and selective use of either immediate or delayed hysterectomy. STUDY DESIGN: This is a retrospective study of deliveries conducted at a tertiary care hospital from 2001 to 2018 with pathology-confirmed PAS. Those with previable pregnancies or microinvasive histology were excluded. To improve the equity of comparison, analyses were made separately among scheduled and unscheduled cases, therefore patients were assigned to one of four cohorts as follows: (1) scheduled/per-algorithm, (2) scheduled/off-algorithm, (3) unscheduled/per-algorithm, or (4) unscheduled/off-algorithm. Primary outcomes included RBCs transfused and estimated blood loss (EBL). Secondary outcomes included perioperative complications and disposition. RESULTS: Overall, 95 patients were identified, with 87 patients meeting inclusion criteria: 36 treated per-algorithm (30 scheduled and 6 unscheduled) and 51 off-algorithm patients (24 scheduled and 27 unscheduled). Among scheduled deliveries, 9 (30.0%) patients treated per-algorithm received RBCs compared with 20 (83.3%) patients treated off-algorithm (p < 0.01), with a median (interquartile range [IQR]) of 3.0 (2.0, 4.0) and 6.0 (2.5, 7.5) units transfused (p = 0.13), respectively. Among unscheduled deliveries, 5 (83.3%) per-algorithm patients were transfused RBCs compared with 25 (92.6%) off-algorithm patients (p = 0.47) with a median (IQR) of 4.0 (2.0, 6.0) and 8.0 (3.0, 10.0) units transfused (p = 0.47), respectively. Perioperative complications were similar between cohorts. CONCLUSION: A multidisciplinary algorithm including P-UAE and selective use of delayed hysterectomy is associated with a lower rate of blood transfusion in scheduled but not unscheduled cases. KEY POINTS: · An algorithm with delayed hysterectomy had less transfusion in scheduled, but not unscheduled, cases.. · Over time, more cases were managed per algorithm; among scheduled cases, the transfusion rate and volume transfused decreased.. · There were similar transfusion outcomes among off-algorithm cases, regardless if delivery was scheduled..

Anesthetic management of placenta accreta spectrum at an academic center and a comparison of the combined spinal epidural with the double catheter technique: A retrospective study.

STUDY OBJECTIVES: To describe the anesthetic management and outcomes of placenta accreta spectrum (PAS) cases at our institution over a 19 year period and to compare outcomes associated with the lumbar combined spinal epidural (CSE) technique versus the double catheter technique (lumbar CSE with thoracic epidural catheter). DESIGN: Retrospective cohort study. SETTING: Labor and delivery unit at a tertiary care center. PATIENTS: 113 female patients who had histologically confirmed PAS on the final pathology report after cesarean delivery or cesarean hysterectomy. INTERVENTION: Neuraxial anesthesia, including CSE and the double catheter technique, and general anesthesia for PAS cases (including scheduled and unscheduled cases and those known or unknown as PAS preoperatively). MEASUREMENTS: The medical records were reviewed for demographic information, intraoperative management, anesthetic technique, and outcomes. We describe anesthetic management and outcomes of cases classified as scheduled vs. unscheduled and known vs. unknown PAS. We also compare the CSE and double catheter techniques with the primary outcome being conversion to general anesthesia (GA). MAIN RESULTS: We included 113 cases: 60 (53.1%) scheduled/known cases, 12 (10.6%), scheduled/unknown cases, 22 (19.5%) unscheduled/known, and 19 (16.8%) unscheduled/unknown cases. All scheduled cases except two were started with a neuraxial technique. General anesthesia (GA) was used to start 18/41 (44%) of unscheduled cases. The double catheter technique (n = 35) was associated with a lower GA conversion rate (5.7% vs. 29.7%, P = 0.036) compared to the CSE technique (n = 37). CONCLUSIONS: Neuraxial anesthesia is the most commonly used technique for PAS cases in our practice. The double catheter technique was associated with lower GA conversion rates compared to the CSE technique in our cohort.

Impact of a multimodal analgesic protocol modification on opioid consumption after cesarean delivery: a retrospective cohort study.

INTRODUCTION: Adequate pain control is a mainstay in enhanced recovery after surgery (ERAS) protocols. ERAS protocols are widely accepted in colorectal and gynecologic surgeries and are increasingly implemented in the obstetric setting. Multimodal analgesia incorporating non-steroidal anti-inflammatory drugs (NSAIDs) and acetaminophen is a mainstay of ERAS protocols for cesarean delivery, but little research has focused on the choice of NSAIDs or timing of initiation in women undergoing cesarean delivery. At our institution, patients undergoing cesarean delivery receive a standardized multimodal analgesic regimen consisting of neuraxial morphine with NSAIDs and acetaminophen. Our initial protocol involved starting the oral analgesics in the recovery room. There was variability in whether these medications were given in a timely manner or withheld in the setting of postoperative nausea and vomiting. We modified this protocol and performed a retrospective analysis to assess the impact of this change on postoperative opioid rescue requirements in women undergoing cesarean delivery under neuraxial anesthesia. METHODS: This retrospective analysis included patients who underwent cesarean deliveries from 1 July 2014 to 22 August 2017. With the initial analgesic protocol, patients received neuraxial morphine, followed by naproxen 500 mg PO Q12 hours and acetaminophen 650-975 mg PO Q6 hours initiated in the recovery room. After protocol revision in January 2016, the same neuraxial morphine dose was used in addition to acetaminophen 975 mg PR at the start of the case and ketorolac 15-30 mg IV at the end of the case. Postoperatively, patients received acetaminophen PO 975 mg Q6 hours, ketorolac IV 15 mg Q6 hours for 3 doses, transitioning to ibuprofen 600 mg Q6 hours. Fentanyl, oxycodone, and intravenous hydromorphone were given for breakthrough pain with both protocols. The primary outcome of the study is the need for rescue opioid analgesia. Secondary outcomes are total opioid usage, time to first rescue opioid, maximum reported pain scores, and need for rescue antiemetics. Univariate and multivariate analyses were performed controlling for variables significantly different between the two cohorts. RESULTS: 3250 patients were included in our analysis (1574 in the old protocol and 1676 in the new protocol). There was no significant difference in patient demographics or intraoperative characteristics between the two cohorts except for more primiparous women (25% vs. 17%), more Pfannenstiel incision (98% vs. 96%), and less repeat cesarean deliveries (40% vs. 44%) in the new protocol cohort. Need for rescue opioids was reduced with the new protocol at 2, 24, and 48 h [(36.46% vs. 75.73%, p < .0001), (74.28% vs 91.99%, p < .0001), (87.53% vs 95.49% p < .0001), respectively]. Among those who received opioids, opioid consumption over 48 h was reduced (median [IQR]: 55 [30, 95] vs. 40 [20, 70] mg oxycodone equivalents) after protocol revision (GMR 0.75, 95% CI 0.7, 0.80, p < .0001). The time to first rescue opioid medication was significantly longer in the new protocol compared to the old protocol (175 [79, 1057] min vs 51 [28, 104] min, p < .001). CONCLUSION: There was a significant decrease in the need for and the dose of rescue opioid medications with the new protocol. This highlights the importance of optimizing the choice of agents, as well as route and timing of administration of the components of the postoperative multimodal analgesic regimen.

Not Your Typical Dyspnea of Pregnancy: A Case Report of Transcatheter Valve-in-Valve Replacement During Pregnancy.

Because technology for valvular replacement continues to evolve, we expect it to be further reaching in the applications for intermediate- to high-risk surgical candidates. Although the patient population for transcatheter aortic valve replacement has widened, it is still extremely rare in the pregnant patient. We report a case of a transcatheter valve-in-valve implantation in the second trimester of pregnancy. The patient experienced an excellent outcome after comprehensive coordination across multiple services. We discuss anesthetic considerations in the care of the pregnant patient for transcatheter aortic valve implantation.
