Cough stress rib fractures in two obstetric patients: case report and pathophysiology.
The clinical presentation of fractured ribs and physiology of cough in two obstetric patients are described to explain why a rib fracture, not a pneumothorax, occurred on coughing in these patients. At total lung capacity the outward expansion of the lower thorax (flare) during a cough is limited. ⋯ A direct expiratory action of abdominal muscles predominates over their indirect inspiratory action. The lower ribs are pulled down by the cough and may even fracture from the enormous intrapleural cough pressures which are generated before the glottis opens.

Obstetric anaesthesia: an approach to improving the standards of services.
There has been considerable discussion about obstetric anaesthesia standards and about the role of peer review in quality improvement. We carried out two postal surveys in 1990 and 1991 in major obstetric departments in Northern England, in order to assess practice and facilities against professionally derived standards, with the aim of stimulating and reviewing change. The reference standards were a local adaptation of those produced by the Obstetric Anaesthetists Association, and covered operating facilities, anaesthetic equipment, management and manpower, training, and protocols. ⋯ This revealed further improvement in 8/26 standards, but apparent deterioration in 11/26. The overall change from the first to the third survey was of apparent improvement in 15/26 standards and deterioration in 6/26. Surveys of practice against professionally derived standards and the targeted feed back of results can lead to improvements in practice and facilities.

Pregnant patients with varicella infections have an increased risk of life threatening pulmonary complications. Prompt diagnosis and aggressive early therapy with acyclovir are important aspects of treating varicella pneumonia. ⋯ Preoperative evaluation of pulmonary function and choice of anesthetic are critical to intraoperative management. This paper presents the successful treatment of varicella pneumonia in the third trimester of pregnancy with survival of both mother and infant.
