Brain Disorders: A Case Study
Neuro | 47total | | Assessment | 2 1A1ND | #Pt presents w/crossed arms that looks like decorticate-do further neuro assess#CPP if normal (70-100) & brain profused 180/60 B/P, ICP 30 what is body trying to do?-compensate to have adequate profusion. MAP (2xDiastolic) + Systolic/3 CPP=MAP-ICP – MAP 70-110 at least 60#Preliminary ICP findingICP pg15355-10mmHg normal, sustained >10mmHg IICPManifestations * 1st sign is change in level of consciousness: behavior & personality change, irritability & agitation, memory and judgment impaired, change in speech * later: coma & unresponsiveness to pain, etc * Hemiparesis weakness on contralateral side of IICP, hemiplegia, abnormal posturing: decrebrate or decorticate * Altered vision, blurred
