Comparative StudyBlood loss and transfusion practice in the perioperative management of craniosynostosis repair.
During the past 5 years, the surgical repair for sagittal synostosis has been modified to a more complex and involved procedure. This led to a retrospective evaluation of the current transfusion practice in a large series of craniosynostosis repairs. The charts of 76 patients (81 surgical procedures) undergoing craniosynostosis repair from January 1990 to November 1996 were examined. ⋯ Packed red blood cell transfusion occurred in 96.3% of the patients and was appropriate for most procedures based on ABL. Thus, transfusion for craniosynostosis repair is almost inevitable, and the preventive preparation of blood on the order of the mean estimated blood loss (EBL) plus 2 SD is appropriate. With the increased complexity of sagittal repair and its performance in a younger population, the cosmetic benefit of surgical repair has major implications for management of blood and fluids.

Randomized Controlled Trial Comparative Study Clinical TrialEffects of nonsteroidal anti-inflammatory drugs on hemostasis in patients with aneurysmal subarachnoid hemorrhage.
Platelet function is impaired by nonsteroidal anti-inflammatory drugs (NSAIDs) with prominent anti-inflammatory properties. Their safety in patients undergoing intracranial surgery is under debate. Patients with aneurysmal subarachnoid hemorrhage (SAH) were randomized to receive either ketoprofen, 100 mg, three times a day (ketoprofen group, n = 9) or a weak NSAID, acetaminophen, 1 g, three times a day (acetaminophen group, n = 9) starting immediately after the diagnosis of aneurysmal SAH. ⋯ Coagulation (prothrombin time [PT], activated partial thromboplastin time [APPT], fibrinogen concentration, and antithrombin III [AT III]) was comparable between the two groups. Ketoprofen but not acetaminophen impaired platelet function in patients with SAH. If ketoprofen is used before surgery on cerebral artery aneurysms, it may pose an additional risk factor for hemorrhage.

Internal jugular vein cannulation in neurosurgical patients: a new approach.
A new approach to internal jugular vein (IJV) cannulation with the head and neck placed in the neutral position is described. The junction of the medial two thirds and lateral one third between the angle of the mandible and symphysis menti is identified. ⋯ In 120 patients studied, the failure rate was 1.66%, and there were no complications. We propose this technique as a safe and reliable alternative in neurosurgical patients.
