Observational Study
I-gel has been used in various clinical situations. The study investigated alterations in respiratory parameters following a stepwise lung recruitment maneuver (LRM) using the i-gel. The research involved 60 patients classified as American Society of Anesthesiologists class I-II, aged 30 to 75 years, undergoing elective urologic surgery. Various respiratory parameters, including lung compliance, airway resistance, leak volume, airway pressure, and oxygen reserve index, were recorded at different time points: before LRM, immediately after LRM, and at 5, 15, and 30 minutes after LRM, as well as at the end of the surgery. The primary outcome was to assess an improvement in lung compliance. Dynamic lung compliance (mean ± SD) was significantly increased from 49.2 ± 1.8 to 70.15 ± 3.2 mL/cmH2O (P < .05) after LRM. Static lung compliance (mean ± SD) was increased considerably from 52.4 ± 1.7 to 65.0 ± 2.5 mL/cmH2O (P < .05) after the LRM. Both parameters maintained a statistically significant increased status for a certain period compared to baseline despite a decreased degree of increment. Airway resistance (mean ± SD) was significantly reduced after the LRM from 12.05 ± 0.56 to 10.41 ± 0.64 L/cmH2O/s (P < .05). Stepwise LRM using i-gel may improve lung compliance and airway resistance. Repeated procedures could lead to prolonged improvements in respiratory parameters.

INTRODUCTION
Cerebral gas embolism is an unusual but extremely serious condition that occurs when air is introduced into the arterial or venous circulation of the brain. Although rare, it can lead to significant neurological deficits and even the death of the patient.
CLINICAL CASE
76-year-old patient with pre-existing diffuse interstitial lung disease, who experienced a massive stroke due to spontaneous pneumomediastinum. Her presentation included confusion, seizures, and motor weakness. Imaging tests revealed air bubbles in the cerebral sulci and hypodense areas in the cerebellum and parietooccipitals. In addition, pneumothorax and air in the upper mediastinum were noted on chest radiographs and chest CT scan. Despite therapeutic measures such as hyperbaric oxygen, the patient unfortunately died due to multiple organ failure.
DISCUSSION
The diagnosis of cerebral gas embolism generally involves performing a cerebral computed tomography, which is highly sensitive for detecting the presence of air in the cerebral vessels. Management includes monitoring of vital and neurological signs, as well as specific measures such as airway closure, venous catheter aspiration, Trendelenburg positioning, and hyperbaric oxygen.
CONCLUSION
Cerebral gas embolism is a potentially fatal condition that requires a brain computed tomography for diagnosis and it is vitally important to know the prevention measures to avoid the appearance of this complication and also to know the general measures to adopt when it occurs.

OBJECTIVES
This prospective observational study aimed to assess the clinical outcomes of perioperative airway and ventilatory management in patients undergoing surgery for oral cavity cancer. The study described the frequencies and types of procedures for securing the airway and the duration and types of postoperative ventilatory support. We compared the findings with those of the TRACHY study.
PATIENTS AND METHODS
One hundred patients undergoing oral cavity oncological surgeries were included. Airway assessment included inter-incisor gap, Mallampati class, neck movements, and radiological features. Surgical parameters, postoperative ventilatory support, and complications were documented.
RESULTS
The buccal mucosa was the most common cancer site (48.0%), and direct laryngoscopy was deemed difficult in 58.0% of patients. Awake fibreoptic intubation or elective tracheostomy was required in 43.0% of cases. Thirty-three patients were extubated on the table, and 34 patients were successfully managed with a delayed extubation strategy. In comparison with the TRACHY study, variations were observed in demographic parameters, tumour characteristics, and surgical interventions. Our mean TRACHY score was 1.38, and only five patients had a score ≥4. Prophylactic tracheostomy was performed in 2.0% of cases, in contrast to the TRACHY study in which 42.0% of patients underwent the procedure.
CONCLUSION
The study emphasizes the challenges in airway management for oral cavity cancer surgery. While prophylactic tracheostomy may be necessary in specific cases, individualized approaches, including delayed extubation, are preferrable to maximize safety. Our findings contribute to better understanding and managing perioperative challenges in oral cancer patients and highlight the need for personalized strategies. Scoring systems like TRACHY should not be accepted as universally applicable.

Angioedema without concomitant urticaria is a well-known complication of treatment with the recombinant tissue-type plasminogen activator (r-tPA) alteplase and its genetically modified variant tenecteplase. It is potentially lethal when causing airway obstruction and can require intubation. The latest guideline for the early management of patients with acute ischemic stroke from the American Heart Association/American Stroke Association advises to treat this complication initially by interfering with the histamine pathway. This article aims to clarify the pathophysiological mechanism of r-tPA-induced angioedema and provides several arguments that this condition is primarily bradykinin-mediated and hence should be treated initially by intervening with the bradykinin pathway. Second, other-less frequently reported-adverse symptoms after r-tPA therapy and their proposed pathophysiological mechanisms leading to specific treatment are described. This manuscript describes the need for an update of the section "3.5 IV alteplase" from the American Heart Association/American Stroke Association guideline to treat this r-tPA-induced angioedema adequately and prevent potentially fatal outcomes.

Observational Study
BACKGROUND AND AIM
Childhood choking is a global health concern that mainly affects children under the age of 5 years. The parent's and caretaker's responsibility is critical in the children's lives and can potentially influence the result of at-home injuries such as choking. We aimed to assess the knowledge, attitude, practice, and associated factors of first aid management toward choking hazards among Saudi adults from the Eastern Province.
METHODS
The present analytical study was carried out among 390 Saudi adults attending different primary health centers in the Eastern Province of Saudi Arabia. We used a standard and validated data research topic tool to assess knowledge, attitude, and practice. Spearman's correlation was applied to determine the correlation between each section, while binomial logistic regression analysis was applied to identify the associated factors.
RESULTS
We observed knowledge, attitude, and practice scores in 43.3, 38.9, and 36.4% of the participants, respectively. Furthermore, positive correlations between knowledge and attitude (rho = 0.42, = 0.001), between knowledge and practice (rho = 0.57, = 0.001), and between attitude and practice (rho = 0.41, = 0.001) were revealed in our survey. The knowledge of the participants was significantly higher with the age group of 30-40 years [adjusted odds ratio (AOR) = 3.67 (1.94-4.65), = 0.001] and participants who received training in first aid management [AOR = 1.64 (1.12-2.49), = 0.037]. This study found that males [AOR = 0.36 (0.21-0.63), = 0.001] and those working in the private sector [AOR = 0.61 (0.31-0.87), = 0.018] had significantly lower attitudes.
CONCLUSION
Our results underscore the importance of continuous health education initiatives and training courses at primary health care centers regarding first aid management of choking hazards to improve awareness and practices. Furthermore, we recommend prospective multicenter studies to address region-specific knowledge gaps.

This study determined whether compared to conventional mechanical ventilation (MV), extracorporeal membrane oxygenation (ECMO) is associated with decreased hospital mortality or fibrotic changes in patients with COVID-19 acute respiratory distress syndrome. A cohort of 72 patients treated with ECMO and 390 with conventional MV were analyzed (February 2020-December 2021). A target trial was emulated comparing the treatment strategies of initiating ECMO vs no ECMO within 7 days of MV in patients with a PaO/FiO < 80 or a PaCO ≥ 60 mmHg. A total of 222 patients met the eligibility criteria for the emulated trial, among whom 42 initiated ECMO. ECMO was associated with a lower risk of hospital mortality (hazard ratio [HR], 0.56; 95% confidence interval [CI] 0.36-0.96). The risk was lower in patients who were younger (age < 70 years), had less comorbidities (Charlson comorbidity index < 2), underwent prone positioning before ECMO, and had driving pressures ≥ 15 cmHO at inclusion. Furthermore, ECMO was associated with a lower risk of fibrotic changes (HR, 0.30; 95% CI 0.11-0.70). However, the finding was limited due to relatively small number of patients and differences in observability between the ECMO and conventional MV groups.

INTRODUCTION AND IMPORTANCE
Pierre Robin Sequence (PRS) is a rare and complex condition that often necessitates the collaboration of a full medical team from various disciplines to save the lives of babies with this genetic mutation, characterized by three clinical manifestations: glossoptosis, micrognathia, and cleft palate. Treatment primarily involves freeing upper airway obstructions and enhancing nutrition to allow the babies to lead a normal life. The lip-tongue adhesion procedure has been identified in medical literature as the recommended approach to addressing the issues associated with Pierre Robin sequence, and this method was successfully adopted in this case.
CASE PRESENTATION
2.5 kg, a newborn male baby with an abnormal position of the tongue and the inability to breastfeed and feed normally, without any medical, family, or social history. Following an examination, it was discovered that the baby had a posterior position of the tongue, micrognathia, and a cleft palate, leading to a diagnosis of Pierre Robin Sequence (Figs. 1, 2). Preparations for the baby's surgery have commenced. The baby was solely fed intravenously and provided with an oxygen mask for 25 days until all necessary consultations were completed and the baby's readiness for surgery and general anesthesia was confirmed. The surgical plan involved attaching the tongue to the lower lip to enhance the tongue's muscular strength, addressing the posterior position issue, and delaying the palate repair until the age of 1.5 years.
CLINICAL DISCUSSION
PRS is a clinical entity characterized by the triad of mandibular hypoplasia (small jaw), glossoptosis (hypotonic, retracted tongue) and respiratory obstruction that require a multidisciplinary team for initial evaluation and management and maintenance care. TLA is a simple and effective procedure for increasing the cross-sectional area of oropharyngeal port.
CONCLUSION
Handling airway obstruction in Pierre Robin Sequence involves various factors, and there is no universal treatment that can address all cases. Appropriate airway management strategies and feeding programs are essential for each individual with PRS. Our review highlights that TLA is a straightforward surgical procedure with minimal or no short-term complications. TLA should be considered as the primary surgical intervention when relief is needed.

INTRODUCTION
The situation in France is unique, having a legal framework for continuous and deep sedation (CDS). However, its use in intensive care units (ICU), combined with the withdrawal of life-sustaining therapies, still raises ethical issues, particularly its potential to hasten death. The legalization of assistance in dying, i.e., assisted suicide or euthanasia at the patient's request, is currently under discussion in France. The objectives of this national survey were first, to assess whether ICU professionals perceive CDS administered to ICU patients as a practice that hastens death, in addition to relieving unbearable suffering, and second, to assess ICU professionals' perceptions of assistance in dying.
METHODS
A national survey with online questionnaires for ICU physicians and nursesaddressed through the French Society of Anesthesiology and Critical Care Medicine.
RESULTS
A total of 956 ICU professionals responded to the survey (38% physicians and 62% nurses). Of these, 22% of physicians and 12% of nurses (p < 0.001) felt that the purpose of CDS was to hasten death. For 20% of physicians, CDS combined with terminal extubation was considered an assistance in dying. For 52% of ICU professionals, the current framework did not sufficiently cover the range of situations that occur in the ICU. A favorable opinion on the potential legalization of assistance in dying was observed in 83% of nurses and 71% of physicians (p < 0.001), with no preference between assisted suicide and euthanasia.
CONCLUSION
Our findings highlight the tension between CDS and assisted suicide/euthanasia in the specific context of intensive care and suggest that ICU professionals would be supportive of a legislative evolution.

OBJECTIVE
Comparative assessment of the level of differentiating growth factor 15 (GDF 15 ) against the background of a 6-month course of respiratory support in the mode of automatic positive pressure in the airways therapy (aPAP therapy) in patients with obstructive sleep apnea syndrome (OSA).
MATERIAL AND METHODS
59 men participated in the study, the average age was 51.9±2.4 years. The main group (MG1) consisted of 30 patients with a verified diagnosis of moderate OSA. 29 men of comparable age and body weight made up the control group (CG) without an objectively confirmed diagnosis of OSA. After the stage of introduction into the study, the type of respiratory support with individual pressure settings was selected for patients with MG1. After 6 months of aPAP therapy with high compliance (at least 85%), the same patients who made up MG2 after treatment underwent repeated polysomnography (PSG) and the GDF 15 content was evaluated. Methods: questionnaire, examination, polysomnography, enzyme immunoassay of blood serum to determine the content of GDF 15.
RESULTS
A 6-month course of aPAP therapy with a high degree of compliance significantly improved the sleep structure and breathing pattern: the representation of NREM 3 increased from 79.2±15.6 to 102.6±21.6 minutes and the REM phase from 56.9± 13.6 to 115.6±26.8. Episodes of apnea were eliminated - apnea-hypopnea index decreased from 21.1 [17.3; 39.1] to 2.5 [1.8; 4.6] and the average values of SaO increased from 85.9% to 91.5%. At the same time, a statistically significant excess of GDF 15 was revealed in MG1 - 20.4 [14.16; 31.71] and MG2 - 17.2 [13.63; 24.44]) in comparison with CG - 13.65 [10.7; 17.09]. Despite the lack of statistical significance, a change in the level of GDF 15 was revealed in the form of a decrease in its concentration after a 6-month course of aPAP therapy.
CONCLUSION
A 6-month course of aPAP therapy made it possible to eliminate intermittent nocturnal hypoxia and improve sleep structure in patients with OSA, as well as reduce the content of GDF 15 protein in blood serum in patients with OSA. However, the tendency to decrease the content of this protein, despite the lack of statistical reliability, confirms the effectiveness of OSA therapy and the possibility of preventing early and pathological aging from the standpoint of somnology and molecular biogerontology.

Zhurnal Nevrologii I Psikhiatrii Imeni... 2024Analysis of factors affecting adherence to continuous positive airway pressure (CPAP) therapy in patients with obstructive sleep apnea (OSA). (Review)
Review
OBJECTIVE
Analysis of factors affecting adherence to continuous positive airway pressure (CPAP) therapy in patients with obstructive sleep apnea (OSA).
MATERIAL AND METHODS
The literature search was carried out using the databases PubMED, Google Scholar, E-library, Cyberleninka for the period 2013-2023 and included reviews and original articles.
RESULTS
The main groups of factors affecting adherence to CPAP therapy in patients with OSA have been established. These include sociodemographic and socioeconomic factors, the severity of OSA and the severity of clinical symptoms, and psychosocial factors. Strategies that can improve adherence were identified (educational technologies for patients, telemedicine technologies, behavioral therapy, modern technical interventions).
CONCLUSION
Factors that improve adherence to CPAP therapy are high levels of education and income, more severe OSA forms accompanied by daytime sleepiness, support from the patient's spouse and social support. Factors such as low levels of education and income, smoking, symptoms of depression and hypochondria, as well as side-effects worsen adherence to CPAP therapy, including refusal to continue treatment. It should be noted that all the identified factors are very closely associated with each other, so it is necessary to evaluate them comprehensively in each patient with OSA.
