Dyspnea in Pregnancy: Specific Dyspneic Syndromes

Category: Pregnancy | Tags: dyspnea, postpartum, Pregnancy, pulmonary, respiratory

Specific Dyspneic Syndromes With that background, we can now discuss some specific disease states in which dyspnea and hypoxia may be the predominant symptoms and signs. Fortunately, many pulmonary diseases are uncommon in the child-bearing years; but this may change as many women are having children later in life. We may see more pregnancies complicated…

Dyspnea in Pregnancy: Mechanical load

Category: Pregnancy | Tags: dyspnea, postpartum, Pregnancy, pulmonary, respiratory

Some amount of breathlessness is a normal physiologic response in pregnant patients. It is so common that 60 to 70 percent of the mothers will experience the sensation in the first two trimesters. Why does this dyspnea occur? Is it an increased mechanical load or an altered respiratory sensation secondary to increased progesterone? The mechanical…

Dyspnea in Pregnancy: Incidence of viral infections

Category: Pregnancy | Tags: dyspnea, postpartum, Pregnancy, pulmonary, respiratory

Although infections are not the main topic of today s conference, several infections deserve attention when we are evaluating the dyspnea cough syndrome of pregnancy. The incidence of viral infections is increased in pregnancy. These patients can have tuberculosis or fungal infections, the most dangerous of which is coccidioidomycosis. We must consider the immunologic changes…

Dyspnea in Pregnancy: Normal Physiology of Pregnancy

Category: Pregnancy | Tags: dyspnea, postpartum, Pregnancy, pulmonary, respiratory

Normal Physiology of Pregnancy Before discussing the other dyspneic syndromes of pregnancy, it is helpful to review the normal physiologic changes in the mother and fetus. There are major effects on the cardiovascular system: increased intravascular volume in the mother, which dilutes laboratory values; increased cardiac output throughout gestation; and increased uterine blood flow. There…

Dyspnea in Pregnancy: Hospital Course

Category: Pregnancy | Tags: dyspnea, postpartum, Pregnancy, pulmonary, respiratory

Hospital Course Dr. South-Rnd: This patient had increasing dyspnea and was admitted to the ICU. She was treated with oxygen by face mask, parenteral aminophyUine and Solu-Medrol, and terbutaline and atropine by nebuli-zation. Within 48 h, her condition had significantly improved. Oral therapy was started, and a therapeutic theophylline concentration was maintained with theophylline (400…

Dyspnea in Pregnancy: Case Discussion

Category: Pregnancy | Tags: dyspnea, postpartum, Pregnancy, pulmonary, respiratory

Case Discussion Let us now review the chest roentgenograms of this patient. On Nov 2 (Fig 1), she had bilateral infiltrates with blunting of both costophrenic angles. There was also silhouetting of the medial half of the left hemidi-aphragm and increased retrocardiac density. One month later (Fig 2), both infiltrates had improved. The chest roentgenogram…

Dyspnea in Pregnancy: Introduction

Category: Pregnancy | Tags: dyspnea, postpartum, Pregnancy, pulmonary, respiratory

Introduction Dr. Tenholder: We selected this case for discussion because asthma and pneumonia are both common problems that internists and chest physicians see in evaluating patients who are pregnant and dyspneic. Internal medicine house staff are also very likely to be consulted by the obstetric service when pregnancy is complicated by many situations in which…

Case Presentation Dr. South-Rtul: Wfe have chosen a patient for this management conference who presented initially at another institution and was transferred for further treatment with a common complication of pregnancy. We will use this patient as an example to discuss some of the management principles that apply to a woman who presents with dyspnea…

Nonsurgical Therapy for Pulmonary Hydatid Cyst Disease: Conclusion

Category: Pulmonary function | Tags: albendazole, cyst, Echinococcus granulosus, hydatid, percutaneous, pulmonary

As just noted, the procedure was not without complications. Why cyst communication with the bronchi occurred is unclear but could be related to shrinkage or damage to tissues from the hypertonic saline solution. Instillation of the hypertonic saline solution into a larger volume of cyst fluid may be less caustic but possibly less cystocidal as…

Nonsurgical Therapy for Pulmonary Hydatid Cyst Disease: Deliberation

Category: Pulmonary function | Tags: albendazole, cyst, Echinococcus granulosus, hydatid, percutaneous, pulmonary

Unintended thin-needle biopsy-aspiration of a hydatid cyst to obtain diagnostic material from mass lesions not considered as possible hydatid cysts at the time of aspiration has been reported in five cases. None of the patients suffered any significant untoward complications or spread of their disease despite evidence of postprocedural cystobronchial communication in two of the…
