We sought to establish normal values for perioperative pressures.  \nMethod: We obtained pressure tracings from prospective clinical trials of forearm and tibia fractures requiring surgery. We standardized data and produced graphs using the ggplot2 library in R version 4.2.2. We generated generalized pressure curves based on the mean pressure and quantile distribution for each time point. Results: We retrieved data from 79 preoperative and 50 postoperative patients. The mean age was 43 years in both groups. Patients exhibited higher pressures postoperatively whether or not they developed ACS. In both the preoperative and postoperative ACS groups, muscle pressure trended upward at an average rate of 0.13 and 0.073 mmHg per hour, respectively, but trended downward in non-ACS groups, at a rate of 0.25 and 0.27 mmHg per hour pre-and postoperatively, respectively. Patients younger than 45 years registered the highest initial postoperative pressure. Postoperative initial pressures were higher than preoperative pressures and were higher among males than females. Females had steeper decreasing pressure curves in both pre-and postoperative scenarios. Conclusion: We observed trends in muscle pressure by sex, age, and diagnosis of ACS among trauma patients. Understanding these variations is essential for improving timely diagnosis of ACS.  \nContexte : La mesure continue de la pression d’un muscle ayant subi un trauma s’estrévélée être une méthode précise pour diagnostiquer un syndrome des loges aigu, mais il n’existe aucune donnée de référence pour témoigner de la réaction qui survient en réponse à une intervention chirurgicale à la suite d’une fracture d’un membre supérieur ou inférieur. Nous avons voulu établir des valeurs normales pour les pressions périopératoires. Méthodes : Nous avons obtenu des tracés de la pression issus d’essais cliniques prospectifs menés chez des personnes ayant une fracture de l’avant-bras ou du tibia nécessitant une intervention chirurgicale. Nous avons normalisé les données et créé des graphiques au moyen de la version 4.2.2 de la bibliothèque ggplot2 de R. Nous avonsgénéré des courbes de pression généralisées fondées sur la pression moyenne et les quantiles de la distribution pour chacun des moments prédéfinis d’évaluation.  \nRésultats : Nous avons colligé des données de 79 patients et patientes avant une intervention chirurgicale et de 50 patients et patientes après une intervention chirurgicale. L’âge moyen était de 43 ans dans les 2 groupes. La pression était plus élevée chez les patients et patientes après l’intervention chirurgicale, que ces personnes aient développé ou non un syndrome des loges aigu. Dans les groupes de personnes atteintes d’un syndrome des loges aigu avant l’intervention chirurgicale et après l’intervention chirurgicale, la pression intramusculaire a eu tendance à augmenter en moyenne de 0,13 et de 0,073 mmHg par heure, respectivement. Elle a cependant eu tendance à diminuer dans les groupes ne présentant pas de syndrome des loges aigu de 0,25 et de 0,27 mmHg par heure avant et après l’intervention chirurgicale, respectivement.
