Abstract
The effect of position, horizontal versus 5° reverse Trendelenburg’s, on the incidence of venous emboli during Caesarean section was evaluated in 207 patients. Venous emboli were diagnosed using precordial ultrasonic Doppler monitoring. In the horizontal position, 44% (60 of 134) parturients had venous emboli compared with 1%(1 of 73) parturients in the 5° reverse Trendelenburg’s position (P < 0.0001). Epidural anaesthesia was performed in 171 patients, and 36 patients had general anaesthesia. In the epidural group, pulse oximetric luiemoglobin oxygen desaturation and complaints of chest pain and/or dyspnoea were associated with the venous emboli. Venous emboli, probably air, occur frequently during Caesarean section with the patient in the horizontal position. This occurrence was minimized by placing the patient in the 5° reverse Trendelenburg’s position. L’ejfet de la position, horizontal versus Fowler de 5° sur l’ incidence de l’ embolie veineuse lors d’une Césarienne fut évalué chez 207 patientes. L’embolie veineuse fut diagnostiquee utilisant une surveillance par Doppler ultrasonique précordial. En position horizontal, 44% (60 de 134) parturientes avaient des embolies veineuses comparee à 1% (1 sur 73) parturientes en position de Fowler de 5° (P < 0.0001 ). L’anesthésie épidurale fut faite chez 171 patientes, et 36 patientes ont reçu de l’ anesthésie générale. Dans le groupe épidural, la saturométrie du pouls a démontré une désaturation et des douleurs rétroslernales et/ou la dysnée était associée avec l’embolie veineuse. L’embolie veineuse, probablement gazeuse, survient fréquémment lors d’une Cesarienne chez les patientes en position horizontale. Cette fréquence fut diminuée en placant les patientes en position de Fowler de 5°.Keywords
