ABSTRACT
INTRODUCTION: Cognitive defects are frequently described after cardiac surgery. They occur in 30 to 79% cases. They might be related to the use of a cardiopulmonary bypass (CPB). They are poorly evaluated in clinical practice. OBJECTIVES: To evaluate the usefulness of the Mini Mental State Examination (MMSE) to screen patients scheduled for cardiac surgery. STUDY DESIGN: Prospective, open study. PATIENTS AND METHODS: 100 consecutive patients undergoing coronary artery bypass or valvular replacement under CPB were enrolled in the study. The MMSE was performed the day before surgery and five days later. Patients exhiting a postoperative defect> or =4 points were compared to those without changes or with improved results. RESULTS: 73 patients completed both tests. The mean score decreased postoperatively in 12 patients (15%). They were older (70+/-8 years), had longer CBP durations (128+/-50 min) and the lowest temperatures (30 degrees C+/-3) compared to the other patients. At the opposite, five patients (9%) improved their scores. CONCLUSION: These results entourage to carry out a more strict follow-up for the oldest patients in cardiac surgery. The MMSE could be systematically integrated to the pre and postoperative screening. The detection of cognitive dysfunction should lead to address the patient to a geriatrician for a prolonged follow-up.

PURPOSE: The authors report a case of bilateral subdural hematoma (SDH) which occurred following epidural analgesia for labour, complicated by post dural puncture headache (PDPH). Physiopathological mechanisms are discussed. CLINICAL FEATURES: A 27-yr-old woman displayed typical PDPH following epidural anaesthesia. On the fifth day she was given a blood patch (BP) which proved immediately effective. Further developments were marked by late recurrence of PDPH and by administration of a second BP on the 24th day. With the aggravation of the headaches, the disappearance of their postural nature and with the appearance of transitory focal neurological signs on the 30th day, a CT-Scan was done and showed bilateral subdural haematoma. Following surgical drainage, the patient made an uneventful recovery. CONCLUSION: The presence of PDPH complicated by a typical neurological deterioration should prompt the anaesthetist to seek an immediate clinical and x-ray diagnosis in order to look for the existence of intracranial complications.
