Postobstruction pulmonary edema.

Several occurrences of pulmonary edema following relief of acute upper airway obstruction have been reported. The edema is associated with normal cardiac filling pressures and responds promptly to conservative therapy. Its origin may be attributed to the cardiopulmonary effects of the vigorous inspiratory effort that the spontaneously breathing patient generates to overcome respiratory obstruction (the Müller maneuver). A patient with postobstruction pulmonary edema complicated by hypovolemia and myocardial infarction is described. Prompt invasive hemodynamic monitoring in selected high-risk patients is suggested.

Bupivacaine-fentanyl epidural analgesia for a parturient in status asthmaticus.

Regional anaesthesia is a suitable technique for the management of the asthmatic parturient. We report the case of an asthmatic gravida in labour in whom prompt institution of bupivacaine-fentanyl epidural analgesia was associated with enhancement of the effectiveness of concurrent medical therapy for bronchospasm. Prior to the initiation of epidural blockade, inhaled atropine was employed in an effort to reduce parasympathetic tone in the bronchial smooth muscle. Sustained clinical improvement did not occur until after delivery of the fetus and placenta.

Maternal cortical vein thrombosis and the obstetric anesthesiologist.

Maternal cortical vein thrombosis is a potentially fatal complication of pregnancy and the puerperium. Patients may present with focal neurologic deficits, seizures, or symptoms indicating increased intracranial pressure. Associated conditions include maternal dehydration and preeclampsia or frank eclampsia. Parturients may require anesthesia for various types of delivery. Safe administration of appropriate anesthesia must take into account the possible presence of a coagulopathy or reduced intracranial compliance. Case presentations, a literature review, possible pathogenetic mechanisms, and specific anesthetic considerations are discussed to enable the obstetric anesthesiologist to develop a rational plan of management.

Scleroderma and pregnancy. Anaesthetic considerations.

The case of a pregnant patient with diffuse scleroderma who died following Caesarean section under general anaesthesia is presented. The patient's postoperative course was complicated by pulmonary oedema and pulmonary hypertension, sepsis, thrombocytopenia and renal failure. Aspects of the disease which possess anaesthetic implications are reviewed.
