Abstract
RATIONALE Managing anesthesia in patients with severe pulmonary conditions involves complex considerations, especially when dealing with high baseline CO2 levels. We present a case that demonstrates the challenges and complexities of anesthesia and postoperative analgesia in a patient with severe pulmonary hypertension and a history of lung disease exacerbated by the interactions of protein-bound drugs. PATIENT CONCERNS A 37-year-old woman at 38 weeks of gestation presented with recurrent chest tightness, shortness of breath, and worsening symptoms over a week, which required emergency medical attention. DIAGNOSIS The patient was diagnosed with severe pulmonary hypertension, and echocardiography revealed a pulmonary artery pressure of 106 mm Hg upon admission. Postoperative complications included sudden unconsciousness after low dose (2 µg) sufentanil administration, indicative of carbon dioxide narcosis that could compound pharmacological interactions and her underlying condition. INTERVENTIONS The patient underwent a cesarean section under spinal anesthesia, which was complicated postoperatively by respiratory depression, requiring naloxone administration and intensive care. OUTCOMES Despite initial postoperative challenges, the patient's condition stabilized, allowing eventual discharge. LESSONS The clinical course highlighted the need for careful monitoring and prompt intervention in anesthesia in patients with severe pulmonary hypertension, particularly when administering multiple protein-bound drugs. Drug interactions can exacerbate the underlying condition, necessitating diligent oversight to prevent severe complications such as carbon dioxide narcosis.

Abstract
Background Variability in obstetric anaesthetia practice and care delivered within the UK is under-explored. The ObsQoR study explored structures, processes, and outcomes of obstetric anaesthesia in 107 hospitals within the UK's National Health Service, and the results of the hospital-level survey are reported here. Methods Hospitals were surveyed to assess obstetric anaesthesia provision, practice, and care delivery. Questions explored staffing, service provision and training, facilities present, clinical practices, outcome measurement, and key indicators of quality in obstetric anaesthesia. Results We received responses from 106 participating hospitals, representing 69% of all UK obstetric units. One hundred (94%) hospitals had a dedicated consultant obstetric anaesthetist within working hours, with 27 (25%) of hospitals' duty anaesthetists having additional clinical responsibilities outside the care of obstetric patients outside of working hours. Around 102 hospitals (98%) offer multidisciplinary team training, of which 95 (93%) use a simulation-based method. Dedicated high-risk antenatal clinics were present in 50 (47%) hospitals. The majority of hospitals provide written patient information in multiple languages for discussing obstetric anaesthesia options (77, 82%). Seventy-three hospitals (69%) use point-of-care testing to estimate haemoglobin concentration. Labour epidural analgesia is most commonly delivered via patient-controlled epidural analgesia in 80 (76%) hospitals, and the incidence of post-dural puncture headaches was recorded by 80 (76%) hospitals. Conclusions These results demonstrate variation in the provision of staffing, facilities, clinical practices, and outcome measurements across the UK. To deliver safe and equitable care across the UK, there needs to be standardisation of anaesthetic peripartum care based on national recommendations and the benchmarking and measurement of appropriate markers of quality.

Abstract
PURPOSE OF THE REVIEW With the increasing prevalence of cesarean section globally, the importance of perioperative analgesia for cesarean section is becoming increasingly evident. This article provides an overview and update on the current status of cesarean section worldwide and associated analgesic regimens. RECENT FINDINGS Some recent studies unveiled potential association of neuraxial analgesia might be associated with children's autism, pharmacologic analgesia in obstetric will potentially gain some more attention. Various commonly used techniques and medications for analgesia in cesarean section are highlighted. While neuraxial administration of opioid remains the most classic method, the use of multimodal analgesia, particularly integration of nonsteroidal anti-inflammatory drugs, acetaminophen, peripheral nerve blocks has provided additional and better options for patients who are not suitable for intrathecal and neuraxial techniques and those experiencing severe pain postoperatively. Optimal pain management is crucial for achieving better clinical outcomes and optimal recovery, and with the continuous development of medications, more and better pharmacologic regimen will be available in the future.

[PMID: 37800789 PMCID: PMC10553133 DOI: 10.1097/md.0000000000034973] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Accepted: 08/07/2023] [Indexed: 10/07/2023] Open
Abstract
This study aims to demonstrate current research priorities and predict future trends of post-cesarean section analgesia by scientometric analysis. We collected nearly 20 years (2002-2021) of publications related to post-cesarean section analgesia in the web of science database. Citespace was applied to evaluate the knowledge mapping. There are 2735 manuscripts about the post-cesarean section in total. The country, institution, and author posted the most separately are the USA, Univ Calif Irvine, and BRENDAN CARVALHO. INTERNATIONAL JOURNAL OF OBSTETRIC ANESTHESIA (21) publishes the most articles of this type, and ANESTHESIOLOGY has the greatest impact (1496 co-citations). In addition, the most key cited reference is McDonnell, J.G (43). Post-cesarean section analgesia research, including spinal anesthesia, postoperative pain, and epidural analgesia, has been a research hotspot in recent years. Through scientometric analysis of the past 20 years, we know the TAP blocks and drug selection in patient-controlled analgesia are the focus of future research. The USA, China, and Turkey have become the main research forces in this field, with high publication rates and centrality. This is important for accurately and quickly locating trends in this field.

[PMID: 37587656 PMCID: PMC10440479 DOI: 10.4274/tjar.2023.221140] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Accepted: 06/13/2023] [Indexed: 08/18/2023] Open
Abstract
Objective Intrathecal morphine is used as an effective component of multimodal analgesia in postoperative analgesia in cesarean section patients. We aimed to analyze the relationship between intrathecal morphine administration and postdural puncture headache (PDPH), pain score and analgesia consumption in the postoperative period, and maternal fetal effects. Methods One hundred four pregnant women aged ≥18 years (American Society of Anesthesiology physical status I or II, >36 weeks gestation) who were scheduled for elective cesarean section under spinal anaesthesia were included in this study. Spinal anesthesia consisted of bupivacaine with or without morphine (Group M: 10 mg heavy marcaine + 25 mcg fentanyl + 100 mcg morphine; Group F: 10 mg heavy marcaine + 25 mcg fentanyl). The effect of intrathecal morphine on PDPH, postoperative pain score, analgesia consumption, and maternal and fetal effects were recorded for 5 days. Results PDPH developed in a total of 33 patients (Group M: 18 and Group F: 15, P=0.274). When we evaluated PDPH with the VAS, there was no significant difference between the groups. The postoperative visual analogue scale (VAS) was lower in the morphine group, and no statistically significant difference was found in the VAS 1st hr and VAS 2nd hr, whereas the VAS 6th hr and VAS 24th hr were found to be statistically significant. There was no difference in terms of PDPH, the first analgesic requirement and postoperative nausea-vomiting, but meperidine consumption was lower in the morphine group. Conclusion Low-dose intrathecal morphine did not affect the incidence of PDPH. It is an effective method that can be used in cesarean section patients without increasing the maternal and fetal side effects from postoperative analgesia.
