[Evaluation of the risk of obstructive sleep apnea in patients awaiting general anesthesia in Burkina Faso]. / Évaluation du risque du syndrome d'apnées hypopnées obstructives du sommeil chez des patients en attente d'une anesthésie générale au Burkina Faso.

INTRODUCTION: General anaesthesia and surgery increase morbidity and mortality in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) who are not known to have OSAHS and therefore not treated before surgery. The objective of this study is to evaluate the risk of OSAHS using the STOP-BANG questionnaire (SBQ) in patients undergoing general anaesthesia in Burkina Faso. MATERIAL AND METHOD: This is a cross-sectional study concerning patients having received pre-anaesthetic consultation from 1st July 2020 to 30th June 2021. Risk of OSAHS is considered "medium to high" when the risk of obstructive sleep apnea is medium or high on SBQ. RESULTS: Our population consisted in 599 persons. A medium to high risk of OSAHS was found in 11.18%. The ASA score and the Mallampati scale were independently associated with moderate to high risk of OSAHS (P<0.001; P<0.001). ASA score of I and Mallampati class of I decreased the risk of OSAHS by 17 and 45% respectively (P=0.012; P=0.031). CONCLUSION: The risk of OSAHS in this population is comparable to that of the general population. Confirmation of OSAHS by ventilatory polygraphy or polysomnography would help to achieve further precision.

[Evaluation of erythrocyte deformability in subjects with sickle cell trait during a soccer game: effect of hydration ad libitum]. / Évaluation de la déformabilité érythrocytaire des sujets porteurs de trait drépanocytaire au cours d'un match de football : effet de l'hydratation ad libitum.

This study compared erythrocyte changes between a group of subjects with sickle cell trait (SCT) and controls (subjects without hemoglobinopathy) during a soccer game in two conditions: with and without hydration. Erythrocyte deformability of subjects was assessed by the coefficient of erythrocyte rigidity (Tk) which was calculated before and after football match. Our results showed a significant increase in erythrocyte rigidity (Tk) in SCT at the end of physical activities without hydration; however when water was provided ad libitum their Tk decreased significantly, reaching values of controls. And adequate hydration is recommended in subjects with sickle cell trait during and after exercise.
