ABSTRACT
OBJECTIVE: Our objective was to determine whether there is a numerical difference between quantitative blood loss (QBL) versus visual estimation of blood loss (EBL) during cesarean delivery (CD), and whether initiation of QBL leads to increased recognition and intervention for postpartum hemorrhage. METHODS: A retrospective review was conducted of 250 patients undergoing CD with only EBL documented and 250 patients undergoing CD with both EBL and QBL documented at Montefiore Medical Center between October 2017 and November 2018. Since May 2018, the protocol for all CD included documentation of EBL and QBL. RESULTS: Average EBL when documented alone (897.0 ml ± 301.0 ml) trended lower than average EBL when documented with QBL (940.0 ml ± 371.0 ml, P = 0.161). For CD with both blood loss documented, average EBL (940.0 ml ± 371.0 ml) was significantly lower than average QBL (1065.3 ml ± 649.8 ml, P = 0.0001). CD with both blood loss documented had a greater number of blood transfusions (24 CD, 9.6%) versus only EBL documented (14 CD, 5.6%) (P = 0.125). CONCLUSION: The use of QBL may function in the algorithm to determine up-front resuscitative intervention to improve maternal outcomes and merits further study.

Congenital myopathies raise unique challenges for anesthesiologists during labor and delivery. Apart from having a risk for malignant hyperthermia, this patient population can present with severe restrictive lung disease in the third trimester. Scoliosis and weak pelvic muscles could make regional anesthesia difficult. The common complications in pregnancy include premature labor, preterm delivery, spontaneous abortion, a prolonged first stage of labor, and uterine atony. We report a case of 28-year-old primigravida of 37 weeks gestation diagnosed with congenital fiber type disproportion successfully managed by a team of high-risk obstetricians, anesthesiologists, and pulmonologists. The patient was closely monitored with serial arterial blood gas to determine carbon dioxide retention in a high-risk labor floor with a backup operating room for cesarean delivery. We reserved a malignant hyperthermia cart and a postpartum hemorrhage cart for emergencies. Our patient was able to deliver vaginally with the help of ultrasound-guided regional anesthesia despite having severe restrictive lung disease and scoliosis. We emphasize a multi-disciplinary team approach for a successful outcome for this patient population.
ABSTRACT
BACKGROUND: The rate of cesarean delivery is on the rise in the USA. Satisfactory postoperative analgesia remains a top priority for cesarean delivery. Multimodal analgesia with a reduction in opioid consumption and improvement in patient satisfaction is a goal for anesthesiologists caring for this patient population. Our study sought to assess whether IV acetaminophen in four divided doses over 24 h decreased pain scores and opioid requirements in patients undergoing cesarean delivery with neuraxial anesthesia. METHODS: 66 patients undergoing elective cesarean delivery under spinal anesthesia with hyperbaric bupivacaine 12 mg, fentanyl 10 µg, and preservative-free morphine 150 µg were randomized to receive either IV acetaminophen or IV placebo for four consecutive doses in the first 24 h postoperatively. The need for rescue medication using morphine equivalence, pain scores, patient satisfaction, and side effects were assessed by a blinded researcher in the first 24 and 48 h postoperatively. RESULTS: There was no difference in opioid requirements in the acetaminophen versus placebo group, 44.32 ± 23 mg versus 47.59 ± 28 mg (p = .607), respectively at 24 h. There was also no difference at 48 h, 57.95 ± 20 mg versus 56.59 ± 22 mg (p = .795). Postoperative pain scores, patient satisfaction, and adverse events were similar in both groups as well. CONCLUSIONS: The results of this study failed to demonstrate any additional benefits of administering multiple doses of IV acetaminophen for treating postoperative pain in patients who have undergone CS surgery and receiving intra-thecal morphine as part of their anesthesia and analgesia. TRIAL REGISTRY NUMBER: NCT02069184.

Among anesthesia-related life-threatening complications, respiratory failure requiring reintubation is common. However, studies evaluating patient characteristics for extubation failure are scarce in the literature. Such knowledge is important to increase awareness and for the development of strategies to improve the safety of anesthesia care. We retrospectively reviewed 196 cases that were reported to our quality assurance (QA) committee from 2004 to 2014 at 3 hospitals. The reintubation rate was 0.09% (n=196). More reintubations occurred in the operating room than the postanesthesia care unit (58% vs 30%). Ninety-three reintubated patients (47%) were 65 years or older. Most patients were in ASA class 3 or 4 (76%) and had a surgical procedure lasting longer than 3 hours. Eleven reintubated patients (5%) died during the hospital course. The exact causes of reintubation could not be determined because of limited data in our QA database. We conclude that although the individual risk of reintubation for each patient is low, the reintubated patients have a higher mortality rate. The study findings emphasize the need for extra vigilance before anesthesia providers attempt extubation of a patient who is elderly, underwent surgery over 3 hours, has chronic obstructive airway disease, or has ASA class 3 or 4 status.

INTRODUCTION: The Bronx is a borough of New York City that has been profoundly affected by the COVID-19 pandemic. Limited reports exist discussing the anaesthetic management of obstetric patients infected with COVID-19. We review a cohort of obstetric patients in the Bronx with COVID-19 and report their delivery data, anaesthetic management, and maternal-fetal outcomes. MATERIAL AND METHODS: We reviewed 92 pregnant patients with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) who delivered between 1 February 2020 and 1 May 2020. Medical records were reviewed for patient characteristics, anaesthetic management, and clinical outcomes. Patients were stratified by mode of delivery and COVID-19 disease severity. RESULTS: Of the 92 deliveries, 49 (53%) were vaginal, 14 (15%) were scheduled caesareans, and 29 (32%) were unscheduled caesareans. 64 patients (70%) were asymptomatic for COVID-19 (mild disease: 18 patients [19%], moderate disease: 7 patients [8%], severe disease: 2 patients [2%], critical disease: 1 patient [1%]). 83 patients (90%) received neuraxial analgesia and/or anaesthesia, with combined spinal-epidural (CSE) and dural puncture epidural (DPE) as the most common techniques. 5 patients (5%) required general anaesthesia (GA) for caesarean delivery, 3 (3%) of whom were intubated for severe or critical COVID-19 disease. CONCLUSIONS: Given the risks associated with SARS-CoV-2 aerosol transmission, GA was avoided in all but the most critically ill patients. CSE and DPE were optimal for minimizing catheter failure rates and risk of conversion to GA. SARS-CoV-2 infection in obstetric patients may be associated with an increased risk for adverse outcomes including preeclampsia, preterm delivery, unscheduled caesarean delivery, and mechanical ventilation.

Introduction: ATTEMPTS to enforce optimization practices for operating room (OR) efficiency are often interpreted as a "pressure for production" which threatens patient safety. The aim of this study is to assess if and how improvements in OR efficiency affect patient safety and thus the quality of care. Methods: In an attempt to optimize OR efficiency, a new OR management approach "Integrated Practice Improvement Solutions" (IPIS) was developed at the Weiler Division of Montefiore Medical Center in 2011. IPIS is a flexible managerial system based on elements of multiple practice improvement methodologies incorporated into an open source framework. It was implemented in 2012. The data presented covers the period from 2012 through 2014 when the system was temporarily discontinued due to administrative restructuring. Data from 2011 was used as a baseline. The impact of IPIS on patient safety and quality of care was assessed based on quality improvement and patient safety (QIPS) Committee reports covering the same period of time. Results: IPIS implementation resulted in an increase in surgical workload by an average of 10.7%, an increase in OR and anesthesia revenues by 18.5% and 6.9%, respectively, and decreases in turnover time by 15% and overtime for the anesthesia staff by 26%. Based on QIPS reports, the total number of complications potentially attributable to "production pressure" was 0.25%, 0.2% and 0.16% in 2012, 2013 and 2014, respectively compared to 0.21% in 2011 (p = 0.56). Conclusions: Gradual implementation of a methodologically structured improvement in OR efficiency has no negative impact on patient safety and quality of care.

Many conventional drugs used today, including isoniazid, dapsone, and acetaminophen, are well recognized culprits of hepatotoxicity. With increasing use of complementary and alternative medical therapies, several herbal medicines, such as Ma-Huang, kava, and chaparral leaf, have been implicated as hepatotoxins. Hepatotoxicity may be the most frequent adverse reaction to these herbal remedies when taken in excessive quantities. A myriad of liver dysfunctions may occur including transient liver enzyme abnormalities due to acute and chronic hepatitis. These herbal products are often overlooked as the causal etiologic agent during the evaluation of a patient with elevated liver function tests. We describe a case of hepatotoxicity due to ingestion of red bush tea diagnosed during preoperative assessment of a patient scheduled for laparoscopic appendectomy. Elevated liver enzymes and thrombocytopenia detected in the patient's laboratory work up confounded the initial diagnosis of acute appendicitis and additional investigations were required to rule out cholecystitis and other causes of hepatitis. Open appendectomy was done uneventfully under spinal anesthesia without any further deterioration of hepatic function.

Liposarcoma, a malignancy of adipose tissue, is the most common soft tissue sarcoma. Patients whose primary tumor cannot be resected or those who have developed metastasis, have poor prognosis since liposarcomas are highly resistant to chemotherapy. We recently generated a spontaneously immortalized cell line, named LS14, from a patient with metastatic liposarcoma. Our goal was to compare the responsiveness of LS14 and SW872 liposarcoma cells to anti-cancer drugs and explore mechanisms of chemoresistance. Using complementary assays for cell viability and number we found that SW872 cells responded robustly to relatively low concentrations of doxorubicin, cisplatin and vinblastine. This reduction in cell viability was due to apoptosis, as evident by phosphatidylserine exposure and caspase 3 cleavage. In contrast, only a high dose of doxorubicin or combination therapy effectively reduced LS14 cell viability and induced apoptosis. LS14 cells showed a higher expression of Bcl-2 and Bcl-xL, but a lower expression of survivin and Bax, than SW872 cells, suggesting that anti-apoptotic proteins contribute to chemoresistance in LS14 cells. Although LS14 cells did not form colonies in soft agar, they generated large tumors and metastases in SCID mice, establishing their tumorigenicity in vivo. In conclusion, LS14 cells are much more resistant to chemotherapy than SW872 cells, making them an excellent model for exploring the efficacy and mechanism of action of anti-cancer drugs in liposarcomas.

We present a case of successful separation of craniopagus conjoined twins. The procedure was staged to permit each child to develop adequate independent cerebral venous drainage and to prevent deleterious, perioperative cerebral edema. Surgical hemorrhage, blood product delivery, and hemodilution were minimized.
