RESUMEN

INTRODUCTION: Surgery is a cost-effective public health intervention. Access to safe surgery is a basic human right. However, there are still significant disparities in the access to and safety of surgical and anaesthesia care between low-income and middle-income countries and high-income countries. The Latin American Surgical Outcomes Study in Paediatrics (LASOS-Peds) is an international, observational, 14-day cohort study to investigate the incidence of 30-day in-hospital complications following elective or emergency paediatric surgery in Latin American countries. METHODS AND ANALYSIS: LASOS-Peds is a prospective, international, multicentre observational study of paediatric patients undergoing both elective and non-elective surgeries and procedures, inpatient and outpatient, including those performed outside the operating room. The primary outcome is the incidence of in-hospital postoperative complications up to 30 days after surgery. Secondary outcomes include intraoperative complications and the need for intensive care unit admission. ETHICS AND DISSEMINATION: This study received approval from the Institutional Review Board of the coordinating centre (Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo) as well as from all the participating centres. The study results are expected to be published in peer-reviewed journals and disseminated at international conferences. TRIAL REGISTRATION NUMBER: NCT05934682.

RESUMEN

BACKGROUND: Pediatric regional anesthesia has been driven by the gradual rise in the adoption of opioid-sparing strategies and the growing concern over the possible adverse effects of general anesthetics on neurodevelopment. Nonetheless, performing regional anesthesia studies in a pediatric population is challenging and accounts for the scarce evidence. This study aimed to review the scientific foundation of studies in cadavers to assess regional anesthesia techniques in children. METHODS: We searched the following databases MEDLINE, EMBASE, and Web of Science. We included anatomical cadaver studies assessing peripheral nerve blocks in children. The core data collected from studies were included in tables and comprised block type, block evaluation, results, and conclusion. RESULTS: The search identified 2409 studies, of which, 16 were anatomical studies on the pediatric population. The techniques evaluated were the erector spinae plane block, ilioinguinal/iliohypogastric nerve block, sciatic nerve block, maxillary nerve block, paravertebral block, femoral nerve block, radial nerve block, greater occipital nerve block, infraclavicular brachial plexus block, and infraorbital nerve block. CONCLUSION: Regional anesthesia techniques are commonly performed in children, but the lack of anatomical studies may result in reservations regarding the dispersion and absorption of local anesthetics. Further anatomical research on pediatric regional anesthesia may guide the practice.

RESUMEN

BACKGROUND: Latin America comprises an extensive and diverse territory composed of 33 countries in the Caribbean, Central, and South America where Romance languages-languages derived from Latin are predominantly spoken. Economic disparities exist, with inequitable access to pediatric surgical care. The Latin American Surgical Outcomes Study in Pediatrics (LASOS-Peds), a multi-national collaboration, will determine safety of pediatric anesthesia and perioperative care. OBJECTIVE: Below, we provide a descriptive initiative to share how pediatric anesthesia in Brazil, Chile, and Mexico operate. Theses descriptions do not represent all of Latin America. DESCRIPTIONS AND CONCLUSIONS: Brazil an upper middle-income country, population 203 million, has a public system insufficiently resourced and a private system, resulting in inequitable safety and accessibility. Surgical complications constitute the third leading cause of mortality. Anesthesiology residency is 3 years, with required rotations in pediatric anesthesia; five hospitals offer pediatric anesthesia fellowships. Anesthesiology is a physician-only practice. A Pediatric Anesthesia Committee within the Brazilian Society of Anesthesiology offers education through seasonal courses and workshops including pediatric advanced life support. Chile is a high-income country, population 19.5 million, the majority cared for in the public system, the remainder in university, private, or military systems. Government efforts have gradually corrected the long-standing anesthesiology shortage: twenty 3-year residency programs prepare graduates for routine pediatric cases. The Chilean Society of Anesthesiology runs a 1-month program for general anesthesiologists to enhance pediatric anesthesia skills. Pediatric anesthesia fellowship training occurs in Europe, USA, and Australia, or in two 2-year Chilean university programs. Public health policies have increased the medical and surgical pediatric specialists and general anesthesiologists, but not pediatric anesthesiologists, which creates safety concerns for neonates, infants, and medically complex. Chile needs more pediatric anesthesia fellowship programs. Mexico, an upper middle-income country, with a population of about 126 million, has a five-sector healthcare system: public, social security for union workers, state for public employees, armed forces for the military, and a private "self-pay." There are inequities in safety and accessibility for children. Pediatric Anesthesiology fellowship is 2 years, after 3 years residency. A shortage of pediatric anesthesiologists limits accessibility and safety for surgical care, driven by added training at low salary and hospital under appreciation. The Mexican Society of Pediatric Anesthesiology conducts refresher courses, workshops, and case conferences. Insufficient resources and culture limits research.

RESUMEN

Abstract Diversion of substances from the care of the intended patient is a significant problem in healthcare. Patients are harmed by the undertreatment of pain and suffering, transmission of disease, as well as the risk associated with impaired vigilance. Healthcare providers may be harmed by the physical and mental impact of their addictions. Healthcare systems are placed in jeopardy by the legal impact associated with illegal routes of drug release including sanction and financial liability and loss of public trust. Healthcare institutions have implemented many measures to reduce diversion from the perioperative area. These efforts include education, medical record surveillance, automated medication dispensing systems, urine drug testing, substance waste management systems, and drug diversion prevention teams. This narrative review evaluates strengths, weaknesses, and effectiveness of these systems and provides recommendations for leaders and care providers.

RESUMEN

BACKGROUND: Early and delayed behavioral changes are well recognized after anesthesia. Intravenous anesthesia may prevent emergence delirium. However, it has not been evaluated as a preventive strategy for delayed postoperative behavior changes. AIMS: We aimed to determine whether intravenous anesthesia is effective at reducing postoperative behavior changes in children undergoing ambulatory endoscopic procedures when compared to inhalation anesthesia. METHODS: This randomized, double-blinded controlled trial was approved by the local IRB. Children aged 1-12 years who underwent ambulatory endoscopic procedures were recruited. Preoperative anxiety was evaluated through the modified Yale Preoperative Anxiety Scale. All children underwent face mask inhalation induction with sevoflurane. After a peripheral line was placed, each child was allocated to sevoflurane or propofol maintenance. Emergence delirium was evaluated through the Pediatric Anesthesia Emergence Delirium scale. The child was discharged home, and behavioral changes were assessed through the Posthospitalization Behavior Questionnaire for Ambulatory Surgery on Days 1, 7, and 14. RESULTS: Overall, 175 children were enrolled. On Day 1 after the procedure, 57 children presented at least one negative behavior. On Days 7 and 14, 49 and 44 children presented at least one negative behavior, respectively. The median number of negative behaviors was similar between the groups. Post hoc analyses showed a moderate correlation between emergence delirium and negative postoperative behavior on Day 7 (r = .34; p = <.001) and an increase of 3.31 (95% CI 1.90; 4.36 p < .001) points in the mean summed score of new negative behaviors for individuals with emergence delirium. CONCLUSION: The incidence of postoperative behavior changes in children undergoing ambulatory endoscopic procedures was similar when comparing intravenous with inhalation anesthesia. Children who experience emergence delirium might show a greater incidence of negative postoperative behavior changes.

RESUMEN

BACKGROUND: Pediatric emergence delirium is characterized by a disturbance of a child's awareness during the early postoperative period that manifests as disorientation, altered attention and perception. The incidence of emergence delirium varies between 18% and 80% depending on risk factors and how it is measured. Reports from Canada, Germany, Italy, United Kingdom, and France demonstrated a wide range of preventive measures and definitions, indicating that there is a lack of clarity regarding emergence delirium. We aimed to assess the practices and beliefs among Brazilian anesthesiologists regarding emergence delirium. METHODS: A web-based survey was developed using REDCap®. A link and QR Code were sent by email to all Brazilian anesthesiologists associated with the Brazilian Society of Anesthesiology (SBA). RESULTS: We collected 671 completed questionnaires. The majority of respondents (97%) considered emergence delirium a relevant adverse event. Thirty-two percent of respondents reported routinely administrating medication to prevent emergence delirium, with clonidine (16%) and propofol (15%) being the most commonly prescribed medications. More than 70% of respondents reported a high level of patient and parent anxiety, a previous history of emergence delirium, and untreated pain as risk factors for emergence delirium. Regarding treatment, thirty-five percent of respondents reported using propofol, followed by midazolam (26%). CONCLUSION: Although most respondents considered emergence delirium a relevant adverse event, only one-third of them routinely applied preventive measures. Clonidine and propofol were the first choices for pharmacological prevention. For treatment, propofol and midazolam were the most commonly prescribed medications.

RESUMEN

Both robotic surgery and head-down tilt increase intracranial pressure by impairing venous blood outflow. Prostatectomy is commonly performed in elderly patients, who are more likely to develop postoperative cognitive disorders. Therefore, increased intracranial pressure could play an essential role in cognitive decline after surgery. We describe a case of a 69-year-old male who underwent a robotic prostatectomy. Noninvasive Brain4careTM intraoperative monitoring showed normal intracranial compliance during anesthesia induction, but it rapidly decreased after head-down tilt despite normal vital signs, low lung pressure, and adequate anesthesia depth. We conclude that there is a need for intraoperative intracranial compliance monitoring since there are major changes in cerebral compliance during surgery, which could potentially allow early identification and treatment of impaired cerebral complacency.

RESUMEN

BACKGROUND: The prevalence of Substance Use Disorders (SUD) and acceptance of drug testing among anesthetists in Brazil has not been determined. METHODS: An internet-based survey was performed to investigate the prevalence of SUD among anesthetists in Brazil, to explore the attitudes of anesthetists regarding whether SUD jeopardizes the health of an impaired provider or their patient, and to determine the provider's perspective regarding acceptance and effectiveness of drug testing to reduce SUD. The questionnaire was distributed via social media. REDCap was utilized to capture data. A sample size of 350 to achieve a confidence level of 95% and confidence interval of 5 was estimated. Study report was based on STROBE and CHERRIES statements. RESULTS: The survey was returned from 1,295 individuals. Most individuals knew an anesthesia provider with a SUD (82.07%), while 23% admitted personal use. The most common identified substances of abuse were opioids (67.05%). Very few respondents worked in a setting that performs drug testing (n = 17, 1.33%). Most individuals believed that drug testing could improve personal safety (82.83%) or the safety of patients (85.41%). Individuals with a personal history of SUD were less likely to believe in the effectiveness of drug testing to reduce one's own risk (74.92% vs. 85.18%, p < 0.0001) or improve the safety of patients (76.27% vs. 88.13%, p < 0.001). CONCLUSIONS: SUDs are common among anesthetists in Brazil. Drug testing would be accepted as a viable means to reduce the incidence although a larger study should be performed to investigate the logistical feasibility.
