To determine the incidence of, and risk factors for, the occurrence of rebleeding between admission and early operation (ultra-early rebleeding) in patients with spontaneous subarachnoid hemorrhage (SAH), the authors reviewed the cases of 179 patients admitted within 24 hours after their last attack of SAH. Thirty-one (17.3%) of these patients had ultra-early rebleeding despite scheduling of early operation (within 24 hours after admission). The incidence of rebleeding significantly decreased as the time interval between the last attack and admission increased. ⋯ Multivariate analysis revealed that the following three factors were independently associated with ultra-early rebleeding: the level of enhancement of platelet sensitivity; the time interval between the last attack and admission; and the level of thrombin-antithrombin complex. On the basis of these findings, the authors suggest that many of the risk factors for ultra-early rebleeding are interrelated. A particularly high risk of ultra-early rebleeding was observed in those patients 1) who had platelet hypoaggregability; 2) who were admitted shortly after their last SAH; and 3) whose thrombin-antithrombin complex levels were extremely high and were thus in severe clinical condition.

Case ReportsManagement of subarachnoid fluid collection in infants based on a long-term follow-up study.
We report the natural history and management of subarachnoid fluid collections in infants and their management based on a longterm follow-up study in 20 cases. These subarachnoid fluid collections were resolved spontaneously in 17 of 20 patients and only 3 by surgical intervention at the age of 2. In our 20 patients the natural history of subarachnoid fluid collection in infants was benign unless the patients sustained head trauma. ⋯ Head trauma may precipitate subdural haematoma in patients with subarachnoid fluid collection. All patients except one who underwent the placement of subdural-peritoneal shunt, attained normal psychomotor development in time. During the follow-up period of 3 to 10 years after resolution of the fluid collection, no patient has had a recurrence once it resolved.

To determine the sensitivity of the initial new-generation CT (NGCT) scan interpretation for detection of acute nontraumatic subarachnoid hemorrhage (SAH) and to decide whether lumbar puncture (LP) should follow a "normal" NGCT scan. ⋯ Initial interpretation of NGCT scans to detect SAH does not approach 100% sensitivity. A "normal" NGCT scan does not reliably exclude the need for LP in patients who have symptoms suggestive of SAH.

Multicenter Study[Anesthesia and intensive care of subarachnoid hemorrhage. A survey on practice in 32 centres].
To assess the current practices in anaesthesia and intensive care in patients experiencing subarachnoid haemorrhage (SAH). ⋯ Twenty-nine French and three non French centers answered the questionnaire. In 14 centers, more than 60 SAH had been treated in the previous year. Angiography was performed under sedation with a benzodiazepine associated with an opioid (54%). Criteria for choosing an endovascular approach were the site of the aneurysm (81%), its neck size (42%) and the underlying disease (42%). Anaesthesia was induced with either propofol (60%) or thiopentone (40%) associated with an opioid and a muscle relaxant. It was maintained with either isoflurane (59%) or propofol (41%). Nitrous oxide was often associated (62%). During anaesthesia, nimodipine (84%), mannitol (69%), anticonvulsants (47%), dopamine (31%) and lidocaine (9%) were also administered. Postoperatively, nimodipine was administered for prophylaxis of vasospasm (97%) and transcranial Doppler was employed to diagnose vasospasm (50%). Other techniques of care included hypervolaemia (89%), controlled arterial hypertension (36%) and haemodilution (36%).
