Lumbar Puncture Still Has an Important Role in Diagnosing Subarachnoid Heemorrhage BMJ 315:1598-1599, Wasserberg,J.&Barlow,P., 1997 See this aricle in Pubmed Article Abstract An early diagnosis of subarachnoid hemorrhage is essential if patients are to undergo appropriate investigation and treatment.It is increasingly common for patients with suspected subarachnoid hemorrhage to initially undergo computed tomography.Although the procedure is sensitive and noninvasive,it does not detect every instance of subarachnoid hemorrhage. Lumbar puncture should be considered in patients who have an acute onset of headache and who are fully conscious but have a normal scan or when the hospital does not have access to a computed tomographic scanner.We report on two patients in whom an early diagnosis of subarachnoid hemorrhage was missed because they did not undergo lumbar puncture.
