| *Classification based on [[GCS]]
| |
| **14-15: Mild
| |
| **9-13: Moderate
| |
| **3-8: Severe
| |
| *B/l pinpoint pupils suggests opiate use or pontine lesion
| |
| *Pretreatment w/ lidocaine has not been shown to improve outcomes
| |
| *All pts on coumadin should have head CT performed
| |
| | |
| == Diagnosis ==
| |
| *Monitor for increased ICP
| |
| **HA, N/V, sz, lethargy, HTN, bradycardia, agonal respirations, posturing
| |
| *Monitor for herniation
| |
| **Ipsilateral fixed and dilated pupil
| |
| **Contralateral motor paralysis
| |
| | |

| #Head of bed @ 30 degrees
| |
| #Prevent:
| |
| ##Hypotension
| |
| ##Hypoxia
| |
| ##Anemia
| |
| ##Hyperthermia
| |
| ##Coagulopathy

| #[[Seizure Prophylaxis in Head Trauma]]
| |
| | |
| ===[[Increased ICP]]===
| |
| #Ensure adequate sedation (prevent gag reflex)
| |
| #IVF to goal MAP >80 (maintains cerebral perfusion)
| |
| #Mannitol
| |
| ##If SBP>90
| |
| ###If SBP>90 in adults use hypertonic saline NaCl 5% 150ml over 10 min
| |
| ##Reduces ICP w/in 30min; duration of action of 6-8hr
| |
| ##Bolus 20% @ 0.25-1 gm/kg as rapid infusion
| |
| ##Monitor I+O to maintain euvolemia
| |
| #Hyperventilation
| |
| ##No longer recommended as prophylactic intervention
| |
| ###Hyperventilation to PaCO2 <25 never indicated
| |
| ##Brief course only recommended if impending herniation (i.e., Cushing reflex)
| |
| ####Maintain PaCO2 28-35 (20 breaths/min)
| |
| #Seizure
| |
| ##Treat immediately
| |
| ##Seizure prophylaxis reduces sz but does not improve long-term outcomes
| |
| #Goal CPP ~60mmHg
| |
| ##If MAP <80, then CPP<60
| |
| ###consider crystalloids or colloids (plasma if INR>1.3)
| |
| ###phenylephrine 10-100mcg/min, or other pressors prn
| |
| ###transfuse PRBCs, Hb>7
