Laryngeal oedema as an obstetric anaesthesia complication: case reports.

Three cases of laryngeal oedema leading to endotracheal intubation difficulties in obstetric anaesthesia are described. The first case occurred immediately postpartum in a patient who developed a swollen face from strenuous bearing down efforts in the second stage of labour. The other two cases were patients with severe preeclampsia including marked generalized oedema. The possibility of the occurrence of laryngeal oedema with resultant endotracheal intubation difficulties in obstetrics should be remembered when endotracheal intubation is considered to avoid the hazard of acid aspiration. The authors prefer the use of regional anaesthetic techniques (if not contraindicated) in obstetrics, and emphasize the use of prophylactic methods to minimize the risk of acid aspiration in connection with general anaesthesia, particularly where endotracheal intubation may be difficult.
