A 37-year-old parturient with severe preeclampsia accompanied by pulmonary edema underwent emergency cesarean section. Pulmonary artery (PA) catheter inserted while the patient was awake revealed hyperdynamic state with increased cardiac index and preload, and decreased systemic vascular resistance. ⋯ Monitoring of PA pressure and cardiac index was continued postoperatively in ICU for fluid management. We conclude that preoperative PA catheterization provides useful hemodynamic information in severe preeclamptic patients associated with persistent oliguria, pulmonary edema and hyperdynamic state.

In our hospital, twenty-one cases of endotracheal tube cuff rupture during naso-tracheal intubation were noted in cases using 725 polyvinyl chloride (PVC) tracheal tubes. We analysed the causes of cuff troubles in these 21 samples of tubes. When the cuffs were inflated, they were not capable of containing the air in most cases. ⋯ We conclude that these cuff damages might have occurred from various causes. A main cause must be passing the tube through the narrow nasal turbinate with spina or crista. Other causes could not only be the use of Magill forceps but also lubrication of the tube with lidocaine spray and placing it in hot water.
