Débits de débit d'oxygène et surveillance du CO2 en fin d'expiration lors de procédures gynécologiques mineures

Procedural sedation (PS) is generally considered to include the stages of moderate and deep sedation of the continuum of anaesthesia . The clinical goals of procedural sedation are to alleviate apprehension, ameliorate the examination, findings, minimize the patients' memories of the incident and to control pain and distress during diagnostic and interventional medical procedures a lot of minor gynaecological procedures can be performed under moderate to deep sedation as ( D\&C Biopsy, hysteroscopic polypectomy and diagnostic hysteroscopies ) The greatest threat to the safety of sedated patient is airway compromise and or respiratory depression . To decrease the risk of airway and respiratory complications, careful attention must be directed toward the appropriate selection of medications, adherence to dosing recommendations, and most importantly the identification of the high-risk patient. Regardless of the clinical scenario or the medications used, appropriate monitoring of the patient's respiratory and physiologic functions is mandatory to rapidly identify respiratory compromise. Respiratory function is usually evaluated by observation of qualitative clinical signs (respiratory rate, depth and effort) and oxygen saturation monitoring. Oxygen desaturation in pulse oximetry usually occurs as a delayed sign , so if the capnograph monitor is used, any increase in EtCO2 during hypoventilation can alert the observing anesthetist to avoid hypoxemia. Capnography is a respiratory monitoring device that has become an accepted standard of care for PS in many circumstances. So, the American Society of Anesthesiology standards for Basic Anesthetic Monitoring require the use of capnography for both moderate and deep sedation.
