Postpartum Guillain-Barré Syndrome: A Case Report and Literature Review.

Guillain-Barré syndrome (GBS) is a rare acute-onset neurological disease with significant morbidity and mortality. The risk of GBS increases after delivery. Labor and delivery presents many possible risk factors for GBS. However, risk factors and prognosis of postpartum GBS remain unclear due to its low incidence. Here, we first present a patient with a history of postpartum GBS who returned for an elective repeat cesarean section (C-section). For her previous delivery, the patient received spinal anesthesia for an urgent C-section. She presented postpartum with jaw pain, facial palsy, respiratory difficulty, progressive bilateral lower extremity weakness, and areflexia. The diagnosis of GBS was confirmed by cerebrospinal fluid (CSF) examination, nerve conduction studies (NCS), and electromyography (EMG). Her symptoms of GBS improved after intravenous immunoglobulin (IVIG) treatment. The patient also had an Escherichia coli-positive urinary tract infection (UTI), which was treated with nitrofurantoin. For her repeat elective C-section, we performed a dural puncture epidural (DPE) anesthesia. After delivery, she was discharged to home uneventfully. She did not report any new neurological symptoms at her three-week follow-up. Here, we also review published cases of postpartum GBS and discuss peripartum anesthetic considerations for patients with GBS, aiming to inform clinical management of postpartum GBS in the future.

Exploring the Efficacy of Ketamine as an Anesthetic and Antidepressant in Postpartum Depression: A Case Study Analysis.

Postpartum depression is a common mental health disorder that affects women within six months after giving birth. It is characterized by sadness, anxiety, and extreme fatigue, which can significantly impact a woman's daily functioning and ability to care for her newborn. While traditional treatments for postpartum depression include therapy and medication, recent studies have shown promising results using ketamine. We present a case of a woman with a history of depression who delivered four children by cesarean section with debilitating postpartum depression in two births and no symptoms of depression in the births where she received ketamine during delivery.

Regional Anesthesia for High-Risk Patients Undergoing Total Knee Arthroplasty: A Case Report.

Total knee arthroplasty (TKA) is a commonly performed surgery for individuals experiencing advanced knee osteoarthritis. Patients undergoing TKA can present with a variety of comorbidities, ranging from the absence of chronic illnesses to the presence of multiple health conditions. The complexity of these comorbidities can pose challenges in carrying out the desired procedure due to the elevated risk profile; this limits the anesthesia modalities that the physician can utilize. Careful consideration of patients' overall health status and personalized anesthesia approaches are crucial to ensure optimal outcomes in this diverse patient population. This case involves an eighty-year-old male with a history of multiple comorbidities who underwent a left TKA. The patient presented a high-risk profile during evaluation, classified as American Society of Anesthesiology (ASA) class IV, which made general and neuraxial anesthesia unfavorable due to high risks. Regional anesthesia was utilized as the sole modality of anesthesia and was successful. This demonstrates that regional anesthesia is a viable option when attending to patients with high risks associated with other anesthesia modalities.

Patient and Operational Factors Do Not Substantively Affect the Annual Departmental Quality of Anesthesiologists' Clinical Supervision and Nurse Anesthetists' Work Habits.

INTRODUCTION: Although safety climate, teamwork, and other non-technical skills in operating rooms probably influence clinical outcomes, direct associations have not been shown, at least partially due to sample size considerations. We report data from a retrospective cohort of anesthesia evaluations that can simplify the design of prospective observational studies in this area. Associations between non-technical skills in anesthesia, specifically anesthesiologists' quality of clinical supervision and nurse anesthetists' work habits, and patient and operational factors were examined. METHODS: Eight fiscal years of evaluations and surgical cases from one hospital were included. Clinical supervision by anesthesiologists was evaluated daily using a nine-item scale. Work habits of nurse anesthetists were evaluated daily using a six-item scale. The dependent variables for both groups of staff were binary, whether all items were given the maximum score or not. Associations were tested with patient and operational variables for the entire day. RESULTS: There were 40,718 evaluations of faculty anesthesiologists by trainees, 53,772 evaluations of nurse anesthetists by anesthesiologists, and 296,449 cases that raters and ratees started together. Cohen's d values were small (≤0.10) for all independent variables, suggesting a lack of any clinically meaningful association between patient and operational factors and evaluations given the maximum scores. For supervision quality, the day's count of orthopedic cases was a significant predictor of scores (P = 0.0011). However, the resulting absolute marginal change in the percentage of supervision scores equal to the maximum was only 0.8% (99% confidence interval: 0.2% to 1.4%), i.e., too small to be of clinical or managerial importance. Neurosurgical cases may have been a significant predictor of work habits (P = 0.0054). However, the resulting marginal change in the percentage of work habits scores equal to the maximum, an increase of 0.8% (99% confidence interval: 0.1% to 1.6%), which was again too small to be important. CONCLUSIONS: When evaluating the effect of assigning anesthesiologists and nurse anesthetists with different clinical performance quality on clinical outcomes, supervision quality and work habits scores may be included as independent variables without concern that their effects are confounded by association with the patient or case characteristics. Clinical supervision and work habits are measures of non-technical skills. Hence, these findings suggest that non-technical performance can be judged by observing the typical small sample size of cases. Then, associations can be tested with administrative data for a far greater number of patients because there is unlikely to be a confounding association between patient and case characteristics and the clinicians' non-technical performance.

Establishment of Labor Epidural Analgesia Service and its Assessment: An Experience in a Hospital of a Middle-Income Country.

OBJECTIVES: Even though the idea of painless birth is more than 100 years old, it is still underrepresented in some parts of the world despite progress in science, education, anesthesia, spinal and epidural needles, development of catheters, new drugs, and infusion pumps. Maternal care should basically be the safety of the patient (in this case two patients) and also provide all kinds of protection in the form of a multidisciplinary team with an anesthesiologist, especially when it comes to pain therapy and anesthesia for women in labor. In this direction, our hospital departments with low or moderate volume of annual births made the decision to educate ourselves for painless childbirth and contribute more to the care of women in labor. The enthusiasm and dedication of our clinical team prevailed and today we have a high standard of labor epidural service. The aim of this study was to evaluate the establishment of the epidural labor service by comparing the effects of epidural analgesia on labor pain and the course of labor. The secondary objectives were to compare satisfaction with epidural analgesia and the impact of epidural analgesia on the delivery mode. MATERIAL AND METHODS:  This was a prospective observational hospital-based study conducted on 100 patients after the establishment of epidural service. Parturients who were signed to receive epidural analgesia formed Group A and parturients who did not request epidural analgesia formed Group B. All parturients are induced in the delivery room with a Bishop score of 5 or higher. RESULTS: Pain intensity measured through the visual analog scale of pain (VAS score) was significantly lower in Group A (n = 46) compared to Group B (n = 50) at measured points of time (p<0.001). There was a fall in the mean VAS score in Group A from 7.94 to 3.86 within 20 minutes of the bolus dose and starting a continuous infusion. Labor progress according to the Bishop score and till the end of the second stage of labor, or to the transfer to the operating theatre, according to the monitored time in Group A was 176 minutes and it was lower in Group B with 155 minutes; however, by test of linearity we do not gain significance (p = 0.2). There were eight parturients in each group (17% vs 16%) who were indicated for surgical delivery. According to Pearson's correlation test for the outcome of labor between parturients receiving epidural analgesia and parturients without epidural analgesia (p = 0.8), we cannot say that epidural analgesia in labor is correlated with the outcome of surgical delivery. CONCLUSION: Establishing a new hospital procedure such as an epidural painless service for childbirth in low or moderate-volume settings of annual births is very challenging. By evaluating epidural labor services in our hospital, we created the best environment for continuous improvement and long-term efficacy and safety of our analgesic techniques aimed at providing excellent care to mothers and their babies.

Barriers to Using Advanced and Pharmacological Behavior Management Techniques: A Survey of Pediatric Dentists in Jeddah, Saudi Arabia.

Aim: In this study, we assessed the use of advanced pharmacological behavior management techniques (BMTs) among pediatric dentists in Saudi Arabia and the barriers to their clinical application. Materials and Methods: This cross-sectional study used a self-administered electronic survey that targeted members of the Saudi Society of Pediatric Dentistry. The questionnaire included questions on five techniques of advanced and pharmacological behavior management recommended by the American Academy of Pediatric Dentistry. Descriptive statistics, frequency, Chi-square test, and Fisher's exact test were used to present the outcomes and independent variables. Results: A total of 57 pediatric dentists completed the survey. Nitrous oxide (N2O) sedation, general anesthesia (GA), and protective stabilization were used regularly by pediatric dentists in 70.2%, 68.4%, and 56.1% of the participants, respectively. A few participants reported using oral (14.0%) or intravenous (IV) sedation (10.5%) regularly. The most common barriers to using these techniques were either dentists' discomfort or the non-availability of the equipment/drugs. Conclusions: The most common method used by pediatric dentists was N2O inhalation sedation, followed by GA and protective stabilization. The participants' use of pharmacological BMTs, including IV and oral sedation, was relatively low.

Clinical Assessment of Preemptive Analgesia on Success of Pulpal Anesthesia and Postendodontic Pain in Children with Irreversible Pulpitis: A Randomized Comparative Study.

Introduction: Optimal pain management of symptomatic pulpitis in formative years goes a long way in developing a positive dental attitude. Efforts should be made to increase the success of anesthesia, thus diminishing negative dental experiences. The aim of the study was to assess the efficacy of preemptive analgesia on the success of pulpal anesthesia following inferior alveolar nerve block (IANB) in children with symptomatic irreversible pulpitis and on reducing postendodontic pain. Materials and methods: The research design was an in vivo, three-group, parallel, quadruple-blind study. A total of 75 patients were randomly allocated to one of the three groups-group I: ibuprofen, group II: combination of ibuprofen and paracetamol, and group III: multivitamin (placebo). Premedication was given 45 minutes before treatment, and patients received IANB in a standardized manner. Pain during pulpectomy was recorded using the face, legs, activity, cry, consolability (FLACC) scale and postoperatively using Wong-Baker's pain rating scale (WBPRS) at 4, 12, and 24 hours. Success was measured if the pain felt was of no or mild intensity. Results: Success of IANB was 64% for ibuprofen, 72% for the combination group, and 40% for the placebo group, with no statistically significant difference between all groups (p = 0.06) on the FLACC scale. At 4 hours postoperatively, a significant difference (p = 0.02) was found among groups with more children experiencing no or mild pain in groups I and II and the highest number of rescue medications taken by the placebo group. Conclusion: Ibuprofen and a combination of ibuprofen and acetaminophen as preemptive analgesics had no significant effect on the success rate of IANB, although it was effective in reducing pain at 4 hours postoperatively.

Evaluation of Changes in Oral Microflora in Children with Early Childhood Caries after Full Mouth Rehabilitation.

Aim: To evaluate the change in microflora in children suffering from severe early childhood caries (ECC) after full mouth rehabilitation. Materials and methods: A total of 60 children, aged 3-5 years suffering from severe ECC who fulfilled the inclusion and exclusion criteria were included in the study. Pooled plaque samples were taken and subjected to quantitative reverse transcriptase polymerase chain reaction (PCR) to obtain baseline mean values of Streptococcus mutans (S. mutans), Streptococcus sobrinus (S. sobrinus), Candida albicans (C. albicans), and Candida dubliniensis (C. dubliniensis) before full mouth rehabilitation was done under general anesthesia. Posttreatment samples were collected at 6, 12, and 18 months. Wilcoxon signed-rank test was used to compare the mean values of S. mutans, S. sobrinus, C. albicans, and C. dubliniensis before and after full mouth rehabilitation. Results: A total of 60 patients recruited for the study were present at the follow-up at 6 and 12 months. At 18 months, 55 patients returned, and five were lost due to follow-up. A statistically significant reduction was seen in all microorganisms at 6, 12, and 18 months compared to baseline values. At 18 months a slight increase in S. mutans, S. sobrinus, and C. albicans was seen. C. dubliniensis was not detected in any cases after full mouth rehabilitation. Caries recurrence was seen in four patients at 18 months. Conclusion: Significant reduction of S. mutans, S. sobrinus, C. albicans, and C. dubliniensis was seen at 6, 12, and 18 months. A complete reduction of only C. dubliniensis was seen. A significant but not permanent reduction of S. mutans, S. sobrinus, and C. albicans. Caries recurrence was seen in 7.27% of patients at 18 months. How to cite this article: Mathew MG, Jeevanandan G, Rathod NN.

Case report: Anesthetic management for removal of tumor thrombus in the inferior vena cava and pulmonary artery in renal cell carcinoma.

Anesthetic management of patients with renal cell carcinoma with tumor thrombus in the inferior vena cava (IVC) is challenging. This paper reports the experience of anesthesia management in a patient with advanced renal cell carcinoma with thrombus accumulation in the IVC, right atrium, and pulmonary artery who underwent radical nephrectomy and tumor thrombus removal assisted by cardiopulmonary bypass. The emboli, measuring approximately 3 × 6 cm in the left inferior pulmonary artery and 4 × 13 cm in the right main pulmonary artery, were removed completely. During incision of the IVC under systemic heparinization, significant blood loss occurred in the surgical field. The surgery took 724 min, and cardiopulmonary bypass took 396 min. Intraoperative blood loss was 22,000 ml. The patient was extubated 39 hours after surgery and stayed in intensive care unit for 3 days. At 1 year follow-up, the patient was in good health and leading a normal life.

Amniotic Fluid Embolism Coagulopathy Guided by the Point-of-Care Quantra QStat® Hemostasis System: A Case Report.

Amniotic fluid embolism (AFE) is a rare pregnancy complication associated with high maternal mortality that occurs during labor or in the early postpartum period. The diagnosis of AFE is challenging because signs and symptoms are common to other obstetric complications. Early identification and management of profound coagulopathy associated with AFE is essential to improve patient survival. We present a case of a 31-year-old woman with placenta previa and clinical suspicion of AFE after cesarean section. Immediately after delivery, the parturient presented hypotension, hypoxia, coagulopathy, and severe postpartum hemorrhage. We hereby discuss the role of the most recently developed point-of-care viscoelastic testing device, the Quantra QStat® system (Stago Group Company; HemoSonics LLC, Durham, NC), for early detection of acute obstetric coagulopathy and guided hemostatic treatment.

Anesthesia Medication Safety in Relation to Pharmacopeia Medication Use Best Practice Initiatives.

Improvement to anesthesia medication safety is a useful and worthwhile area of research. Anesthesia is one of the few healthcare professions to have immediate access to compounding and label high-hazard medications at the bedside. There is a need to assess the perceptions of anesthesia medication safety and this relationship with pharmacopeia's updated recommendations for anesthesia to improve medication safety and prevent adverse drug events. Certified registered nurse anesthetist (CRNA) perceptions of medication safety climate in Florida were measured utilizing a validated Likert-scale that merged the Attitudes Questionnaire themes of teamwork, climate, safety climate, job satisfaction, stress recognition, perceptions of management, and working. The Agency for Healthcare Research and Quality Hospital Survey on Patient Safety Culture themes utilized were organizational learning, error communication, and support for patient safety. The overall email invitations delivered 5,890, 524 participants voluntarily started, and 401 completed the questionnaire resulting in a 77% completion rate. The overall response rate was 8.896% and 6.8% overall completion rate. The findings demonstrate a correlation between themes related to supportive organizational learning, stress reduction, positive changes, and creating anesthesia medication quality improvements. CRNAs' openness in adopting new pharmacopeia best practice recommendations can improve anesthesia medication safety delivery. The survey indicated clinical noteworthiness that supports the importance of additional examination of frontline providers' perceptions regarding anesthesia medication safety, buy-in, and adoption of updated pharmacopeia recommendations.

Improving CRNAs' Confidence and Perceived Knowledge of Endosurgical Patients Who Use Marijuana: A Quality Improvement Project.

Although some researchers have reported health-related benefits of marijuana, others have reported adverse side effects in nearly every organ system. Patterns of marijuana use are evolving, as is researchers' understanding of marijuana use for healthcare. Despite these findings and developments, nurse anesthetists are inadequately educated about marijuana's perioperative effects on endosurgical patients. As a result, many nurse anesthetists lack confidence in and knowledge of the perioperative care of endosurgical patients under the influence of marijuana. This lack of confidence and knowledge limits the ability of nurse anesthetists to provide optimal care, threatens patient safety, and potentially impairs surgical outcomes. To improve the confidence and perceived knowledge of certified registered nurse anesthetists (CRNAs) regarding perioperative care of endosurgical patients who use marijuana, a quality improvement project was conducted in a metropolitan endosurgical center in California. After the project, participating CRNAs (N = 15) reported increased confidence (z = -0.982; P = .325, > .05) and significantly improved perceived knowledge (z = -3.04; P = .002, < .05) regarding care of patients who use marijuana. For endosurgical patients who used marijuana prior to their procedure, knowledgeable and confident anesthesia care for the side effects of marijuana substantially improved the quality of care, communication, and reduced cancellations.

Quantitative Neuromuscular Monitoring Permits Early Diagnosis of Abnormal Butyrylcholinestrase: Two Case Studies Demonstrating Prevention of Awareness from Premature Awakening.

Administration of succinylcholine to patients with a variant in the butyrylcholinesterase (BChE) gene increases the risk of anesthesia emergence prior to recovery from neuromuscular blockade (NMB). Application of quantitative neuromuscular monitoring (NMM) can identify residual NMB. We present two patients with abnormal BChE gene variants. In the first case, quantitative monitoring was applied too late to prevent awareness, but allowed diagnosis and prevented admission to the intensive care unit. In the second case, monitoring was applied prior to NMB, which enabled early diagnosis and prevented premature awakening from anesthesia. These cases illustrate the importance of quantitative NMM, even in short cases and with short-acting depolarizing agents such as succinylcholine. The clinical implications of this report include a more consistent use of NMM to identify and manage patients with undiagnosed abnormal BChE and to prevent premature anesthesia emergence.

Continuity with caveats in anesthesia: state and response entropy of the EEG.

The growing use of neuromonitoring in general anesthesia provides detailed insights into the effects of anesthetics on the brain. Our study focuses on the processed EEG indices State Entropy (SE), Response Entropy (RE), and Burst Suppression Ratio (BSR) of the GE EntropyTM Module, which serve as surrogate measures for estimating the level of anesthesia. While retrospectively analyzing SE and RE index values from patient records, we encountered a technical anomaly with a conspicuous distribution of index values. In this single-center, retrospective study, we analyzed processed intraoperative electroencephalographic (EEG) data from 15,608 patients who underwent general anesthesia. We employed various data visualization techniques, including histograms and heat maps, and fitted custom non-Gaussian curves. Individual patients' anesthetic periods were evaluated in detail. To compare distributions, we utilized the Kolmogorov-Smirnov test and Kullback-Leibler divergence. The analysis also included the influence of the BSR on the distribution of SE and RE values. We identified distinct pillar indices for both SE and RE, i.e., index values with a higher probability of occurrence than others. These pillar index values were not age-dependent and followed a non-equidistant distribution pattern. This phenomenon occurs independently of the BSR distribution. SE and RE index values do not adhere to a continuous distribution, instead displaying prominent pillar indices with a consistent pattern of occurrence across all age groups. The specific features of the underlying algorithm responsible for this pattern remain elusive.

Postoperative cognitive disorders and delirium in gynecologic surgery: Which surgery and anesthetic techniques to use to reduce the risk?

Despite their general good health, an increasing proportion of elderly individuals require surgery due to an increase in average lifespan. However, because of their increased vulnerability, these patients need to be handled carefully to make sure that surgery does not cause more harm than good. Age-related postoperative cognitive disorders (POCD) and postoperative delirium (POD), two serious consequences that are marked by adverse neuropsychologic alterations after surgery, are particularly dangerous for the elderly. In the context of gynecologic procedures, POCD and POD are examined in this narrative review. The main question is how to limit the rates of POCD and POD in older women undergoing gynecologic procedures by maximizing the risk-benefit balance. Three crucial endpoints are considered: (1) surgical procedures to lower the rates of POCD and POD, (2) anesthetic techniques to lessen the occurrence and (3) the identification of individuals at high risk for post-surgery cognitive impairments. Risks associated with laparoscopic gynecologic procedures include the Trendelenburg posture and CO2 exposure during pneumoperitoneum, despite statistical similarities in POD and POCD frequency between laparoscopic and laparotomy techniques. Numerous risk factors are associated with surgical interventions, such as blood loss, length of operation, and position holding, all of which reduce the chance of complications when they are minimized. In order to emphasize the essential role that anesthesia and surgery play in patient care, anesthesiologists are vital in making sure that anesthesia is given as sparingly and quickly as feasible. In addition, people who are genetically predisposed to POCD may be more susceptible to the disorder. The significance of a thorough strategy combining surgical and anesthetic concerns is highlighted in this article, in order to maximize results for senior patients having gynecologic surgery.

The Year in Review: Anesthesia for Congenital Heart Disease 2023.

This review highlights published literature in 2023 that is related to the anesthetic management of patients with congenital heart disease (CHD). Though not inclusive of all topics, 31 articles are discussed and four primary themes emerged: transfusion and hemostasis, outcomes and risk assessment, monitoring, and pharmacology.

Relationship between preinduction electroencephalogram patterns and propofol sensitivity in adult patients.

PURPOSE: To determine the precise induction dose, an objective assessment of individual propofol sensitivity is necessary. This study aimed to investigate whether preinduction electroencephalogram (EEG) data are useful in determining the optimal propofol dose for the induction of general anesthesia in healthy adult patients. METHODS: Seventy healthy adult patients underwent total intravenous anesthesia (TIVA), and the effect-site target concentration of propofol was observed to measure each individual's propofol requirements for loss of responsiveness. We analyzed preinduction EEG data to assess its relationship with propofol requirements and conducted multiple regression analyses considering various patient-related factors. RESULTS: Patients with higher relative delta power (ρ = 0.47, p < 0.01) and higher absolute delta power (ρ = 0.34, p = 0.01) required a greater amount of propofol for anesthesia induction. In contrast, patients with higher relative beta power (ρ = -0.33, p < 0.01) required less propofol to achieve unresponsiveness. Multiple regression analysis revealed an independent association between relative delta power and propofol requirements. CONCLUSION: Preinduction EEG, particularly relative delta power, is associated with propofol requirements during the induction of general anesthesia. The utilization of preinduction EEG data may improve the precision of induction dose selection for individuals.

Evaluation of acceptance and preference of topical lidocaine application versus articaine injection anesthesia after nonsurgical periodontal treatment: A randomized clinical trial.

BACKGROUND: To compare acceptance and preference of topical lidocaine gel anesthesia with articaine injection anesthesia in patients with moderate periodontitis undergoing scaling and root debridement. METHODS: Ninety-one patients completed this randomized multicenter split-mouth controlled study and underwent two separate periodontal treatment sessions on different days, one with a topical intrapocket lidocaine gel application and the other with an articaine injection anesthesia in a different order depending on randomization. Parameters measured were the patients' preference for topical lidocaine gel anesthesia or injection anesthesia with articaine (primary efficacy criterion), their maximum and average pain, and their intensity of numbness as well as experience of side effects; the probing depth; and the dentists' preference and their evaluations of handling/application, onset and duration of anesthetic effect, and patient compliance. RESULTS: After having experienced both alternatives, 58.3% of the patients preferred the topical lidocaine gel instillation into the periodontal pockets. The safety profile of the lidocaine gel differed positively from the safety profile of articaine injection in type and frequency of adverse drug reactions. The dentists' acceptance and preference regarding either anesthetic method studied were balanced. CONCLUSIONS: Instillation of lidocaine gel into the periodontal pocket is a preferred alternative to injection anesthesia for most of the patients and an equivalent alternative for dentists in nonsurgical periodontal therapy.

Non-traumatic complete cervical spine dislocation with severe fixed kyphosis: successful multidisciplinary approach to a challenging case.

BACKGROUND: To our knowledge, there is no previous report in the literature of non-traumatic neglected complete cervical spine dislocation characterized by anterior spondyloptosis of C4, extreme head drop, and irreducible cervicothoracic kyphosis. CASE PRESENTATION: We report the case of a 33-year-old Caucasian man with a 17-year history of severe immune polymyositis and regular physiotherapy who presented with severe non-reducible kyphosis of the cervicothoracic junction and progressive tetraparesia for several weeks after a physiotherapy session. Radiographs, computed tomography, and magnetic resonance imaging revealed a complete dislocation at the C4-C5 level, with C4 spondyloptosis, kyphotic angulation, spinal cord compression, and severe myelopathy. Due to recent worsening of neurological symptoms, an invasive treatment strategy was indicated. The patient's neurological status and spinal deformity greatly complicated the anesthetic and surgical management, which was planned after extensive multidisciplinary discussion and relied on close collaboration between the orthopedic surgeon and the anesthetist. Regarding anesthesia, difficult airway access was expected due to severe cervical angulation, limited mouth opening, and thyromental distance, with high risk of difficult ventilation and intubation. Patient management was further complicated by a theoretical risk of neurogenic shock, motor and sensory deterioration, instability due to position changes during surgery, and postoperative respiratory failure. Regarding surgery, a multistage approach was carefully planned. After a failed attempt at closed reduction, a three-stage surgical procedure was performed to reduce displacement and stabilize the spine, resulting in correct spinal realignment and fixation. Progressive complete neurological recovery was observed. CONCLUSION: This case illustrates the successful management of a critical situation based on a multidisciplinary collaboration involving radiologists, anesthesiologists, and spine surgeons.

Anesthesia experience in an adult Silver-Russell syndrome: a case report.

BACKGROUND: There are no reports of anesthesia use in adult patients with Silver-Russell syndrome (SRS). Here, we report our experience with anesthesia in an adult patient with SRS complicated by chronic respiratory failure. CASE PRESENTATION: A 33-year-old woman was clinically diagnosed with SRS. She had severe chronic respiratory failure, complicated by superior mesenteric artery syndrome. Percutaneous gastrostomy was scheduled for nutritional management under epidural anesthesia; however, soon after esophagogastroduodenoscopy was started, she lost consciousness and spontaneous respiration. The patient was urgently intubated and converted to general anesthesia. The end-tidal carbon dioxide tension was > 90 mmHg at intubation. CONCLUSIONS: Adult SRS patients with chronic respiratory failure have a risk of CO2 narcosis. SRS also requires preparation for difficult airway management during the perioperative period.
