Comparative Study
Prothrombin complex concentrate for oral anticoagulant reversal in neurosurgical emergencies.
The incidence of spontaneous intracranial haemorrhage has increased markedly in line with the increased use of oral anticoagulant agents. Recent guidelines for reversal of this acquired coagulation defect in an emergency have been established, but they are not adhered to in all centres. Our unit is referred between 20 and 60 patients per year (1994-1999) who are anticoagulated and require urgent neurosurgical intervention. ⋯ Mean International Normalised Ratios of Group 1 were 4.86 pretreatment and 1.32 posttreatment, and of Group 2 were 5.32 and 2.30, respectively. Results for complete reversal and reversal time were significant for PCC with p < 0.001. We recommend PCC for rapid and effective reversal of warfarin in life-threatening neurosurgical emergencies.

The cause and incidence of reductions in cerebral perfusion pressure, and rises in intracranial pressure have been examined in a series of patients with severe head injury defined as an initial Glasgow Coma Sum of less than or equal to 8. Two-hundred-and-seven adults (aged over 16 years) and 84 children admitted to Newcastle General Hospital, who had intracranial pressure monitoring as part of their routine management, were studied. Intracranial pressure (ICP), arterial pressure and cerebral perfusion pressure (CPP) were sampled and recorded every 2 min. ⋯ Diffuse Injury Type I stood out from all the other categories as the only one where reductions in perfusion pressure were almost exclusively due to reductions in arterial pressure and not to increases in ICP. The management of these patients should ensure the adequacy of perfusion pressure by maintaining arterial pressure at a satisfactory level. These results suggest that vigilant monitoring of both intracranial pressure and arterial pressure is required to lower the incidence of secondary insults.

Three cases of self-inflicted head trauma using a captive-bolt pistol are described. This is a rarely reported phenomenon and presents with an unique pattern of brain injury.

The objective of the investigation was to prevent the stigmatizing effect of a totally or partially shaved head with openly visible signs of a head operation, easing the reintegration of the patient into his daily life. After extended surface cleaning with a colourless, regular skin disinfection liquid (undyed isopropanol/dibrom/propylenglycol solution) the hair was combed apart from the incision line before draping. Wound closure was performed as usual, taking care to remove meticulously hair from the wound. ⋯ This percentage corresponds very well to our general infection rate of 0.6%. All patients very much appreciated the offered opportunity and the result. If the objective is to give patients a psychological advantage by preventing a partially bald head we think one can safely refrain from the shaving procedure without risking a higher infection rate.

We describe a patient who developed a brain abscess 52 years after sustaining a penetrating craniocerebral shrapnel injury. For 10 years he had suffered from diabetes mellitus, a disorder known to predispose to infections from a diminished body defence. The treatment and aetiology of this rare occurrence is discussed.
