Maxillofacial trauma is prevalent, particularly among the young population, often stemming from assaults, road accidents, or sports-related mishaps. Traditional intubation methods for managing these injuries can be challenging, especially with occluso-facial fractures requiring intermaxillary blocking for dental articulation restoration. Effective management requires interdisciplinary collaboration between emergency physicians, anesthetists, and maxillofacial surgeons. Proficiency in techniques like the vigilant fiberoptic approach should be emphasized through specialized training courses. This collaborative approach ensures the best possible strategy for managing difficult airways, with input from all stakeholders including patients, students, and practitioners. In this case, we successfully conducted a rapid-sequence awake fiberoptic oral intubation on a trauma patient, during the last earthquake that hit Morocco, with severe craniofacial injuries and an unstable skull. The patient, a 40-year-old woman, presented with complex facial fractures, including hemi lefort III on the right and hemi lefort II on the left, along with minimal subarachnoid hemorrhage and frontal pneumocephalus. Due to the patient's compromised airway from diffuse facial bleeding and low oxygen saturation, we opted for awake fiberoptic intubation once immediate life-threatening issues were addressed. This approach allowed us to maintain the patient's spontaneous respirations and navigate around unstable craniofacial structures. The procedure was performed with meticulous care, considering the patient's unstable skull, and was successful without complications. Post-intubation, the patient was extubated, and her recovery was uneventful., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background: Post-induction hypotension (PIH) is a common side effect of general anaesthesia and is associated with poor perioperative outcomes. We assessed the ability of two point-of-care echocardiographic variables to predict the occurrence of PIH: the passive leg raising-induced changes in the velocity-time integral of the left ventricular outflow tract (ΔVTI-PLR) and the inferior vena cava collapsibility index (IVC-CI)., Methods: We studied 64 patients > 50 years scheduled for elective abdominal surgery. ΔVTI-PLR and IVC-CI were prospectively obtained before general anaesthesia induction. PIH was defined by a systolic arterial pressure < 90 mmHg or a mean arterial pressure < 65 mmHg or by a decrease in systolic or mean arterial pressure > 30% from pre-induction level. Intraclass correlation coefficients (ICCs) were calculated to assess the reproducibility of echocardiographic measurements. Receiver operating characteristic (ROC) curves with 95% confidence intervals (CIs) were generated to test the ability of ΔVTI-PLR and IVC-CI to predict the occurrence of PIH., Results: PIH occurred in 33 (51%) patients. The ICCs for VTI and IVC measurements showed excellent reproducibility. The occurrence of PIH was accurately predicted by ΔVTI-PLR with an area under the ROC curve (AUROC) of 0.89 (95% CI: 0.80-0.97), a threshold value of 18% with a sensitivity of 88% (95% CI: 71-97%) and a specificity of 84% (95% CI: 66-94%). The occurrence of PIH was poorly predicted by IVC-CI with an AUROC of 0.68 (95% CI: 0.54-0.80) and a threshold value of 42%., Conclusions: ΔVTI-PLR, unlike IVC-CI, could reliably predict the occurrence of PIH. The use of ΔVTI-PLR could help individualise anaesthesia management to prevent PIH., (Copyright © 2022 Société française d'anesthésie et de réanimation (Sfar). Published by Elsevier Masson SAS.

Spontaneous pneumomediastinum is a rare disease. It especially affects young adults. The onset is usually sudden, involving chest pain, subcutaneous emphysema and dyspnea. We report the case of a 24-year old asthmatic patient with pneumomediastinum after coughing effort. The patient presented with acute respiratory failure associated with retrosternal chest pain. Chest X-ray confirmed the diagnosis of pneumomediastinum. The patient evolved favorably within 4 days after exsufflation, oxygen therapy and conventional medical treatment., Competing Interests: Les auteurs ne déclarent aucun conflit d'intérêt.

Fentanyl (N-phenyl-N-(1-2-phenylethyl-4-piperidyl)propanamide) is a potent synthetic narcotic analgesic. He has an analgesic effect 100 times greater than that of morphine. The use of transdermal fentanyl delivrery systems has increased over recent years especially in patients with chronic pain who are already treated with high doses of morphine or it is derivate. However, many cases of fentanyl intoxication through a variety of transderrmal systems have been reported. This paper reports a fatality due to excessive administered Fentanyl Sandoz® Matrix 50 µg/h transdermal therapeutic systems.

Purpose: The ability of the parasacral sciatic nerve block (PSNB) to induce anesthesia of the obturator nerve remains controversial. Our objective was to evaluate the anesthesia of the obturator nerve after a PSNB., Methods: Forty patients scheduled to undergo knee surgery (anterior cruciate ligament reconstruction) were included in this prospective, randomized, controlled study. Patients were randomized to receive PSNB alone (control group, n = 20) or PSNB in combination with an obturator nerve block (obturator group, n = 20). After evaluation for 30 min, the two groups received a femoral nerve block, and patients were taken to surgery. The obturator nerve blockade was assessed by measurement of adductor strength at baseline (T0) and every 10 min during the 30-min evaluation (T10, T20, and T30). Pain scores after tourniquet inflation and during surgery were compared between the two groups. The requirement for additional intravenous analgesia and/or sedation was also recorded., Results: The two groups had comparable demographic and surgical characteristics. Four patients were excluded from the study because of PSNB or femoral nerve block failure. The adductor strength values were similar between groups at T0 but were significantly lower in the obturator group at T10, T20, and T30 (p < 0.0001). Patients in the obturator group reported less pain than those in the control group (p < 0.05). They also required less additional intravenous sedation and/or analgesia (p < 0.05)., Conclusion: This clinical study demonstrated that the PSNB is an unreliable means of inducing anesthesia of the obturator nerve and emphasizes the need to block this nerve separately to induce adequate analgesia during knee surgery.
