PRE HOSPITAL
  • C-spine precautions if head or neck injury is suspected
  • Elevation of head with C-spine control
  • Initial pre-hospital responder must ascertain neurologic defect to be able to note progression of symptoms
INITIAL STABILIZATION/THERAPY
  • Manage airway and resuscitate as needed:
    • Patients with depressed level of consciousness should be intubated immediately for controlled ventilation
  • Early neurosurgical consultation
ED TREATMENT/PROCEDURES
  • Prompt neurosurgery and/or neurology consultation
  • BP management:
    • Must use caution in BP control because acute lowering of BP to normal in setting of increased ICP could reduce cerebral perfusion to ischemic levels
    • Use labetalol, nicardipine, esmolol, enalapril to lower diastolic BP initially by 10%
    • Normotensive levels should be achieved over 12–24 hr
    • May use nitroprusside, nitroglycerin, or hydralazine as an alternative
  • Treatment of elevated ICP:
    • Controlled ventilation to PaCO
      2
      of 35 Torr
    • Fluid restriction; elevate head of bed 30°
    • Mannitol—osmotic diuresis
    • Use furosemide as an alternative
  • Correct coagulopathies:
    • Consider fresh frozen plasma (FFP), platelets, prothrombin complex concentrates, vitamin K
  • Consider anticonvulsants
    • Phenytoin, fosphenytoin
MEDICATION
  • Esmolol: 0.5–1 mg/kg initial bolus IV, followed by 50–150 μg/kg/min infusion
  • Enalapril: 1.25–5 mg q6h (risk of precipitous BP lowering, test dose 0.625 mg)
  • FFP: 10–20 mL/kg IV
  • Fosphenytoin: 15–20 mg/kg phenytoin equivalents (PE) at rate of 100–150 mg/min IV/IM
  • Furosemide: 20–40 mg (peds: 0.5–1 mg/kg/dose) IV; may repeat as necessary
  • Hydralazine: 10–40 mg (peds: 0.1–0.2 mg/kg/dose; max. 20 mg/dose) IV; may repeat as necessary
  • Labetalol: 20 mg (peds: 0.3–1 mg/kg/dose; max. 20 mg/dose) IV; may give additional 40–80 mg IV q10min to max. 300 mg
  • Mannitol: 1 g/kg IV
  • Nicardipine: 5–15 mg/h infusion
  • Nitroprusside: Start 0.25–10 μg/kg/min IV (max. 10 μg/kg/min); titrate to effect
  • Phenytoin: 15–20 mg/kg/dose (peds: 15 mg/kg) at rate of <40–50 mg/min
  • Platelet: 1–2 U IV in consultation with neurosurgery
  • Prothrombin complex concentrates: 500–1,000 IU IV
  • Vitamin K: 5–10mg IV over 30 min
FOLLOW-UP
DISPOSITION
Admission Criteria
  • To OR if surgical intervention is indicated
  • To ICU if intubated, altered level of consciousness, or on IV infusion for BP control
  • Admit to neurologic observation unit if normal neurologic exam without evidence of progression of bleed and hemodynamically stable
Discharge Criteria

All patients with intracerebral hemorrhage should be admitted

Issues for Referral

Rehabilitation is a key aspect of recovery

FOLLOW-UP RECOMMENDATIONS
  • Treating HTN in the nonacute setting is the most important step to reduce the risk of intracerebral hemorrhage
  • Discontinuation of smoking, alcohol use, and cocaine use prevents recurrence of intracerebral hemorrhage
PEARLS AND PITFALLS
  • Brain imagining is a crucial part of emergent evaluation of patients with headache, HTN, and/or altered level of consciousness
  • Cautious BP control because acute lowering of BP to normal in setting of ICP could reduce cerebral perfusion to ischemic levels
  • Consider delayed intracranial bleed in patients on anticoagulation with head trauma

INTUSSUSCEPTION

BASICS
DESCRIPTION
  • The proximal bowel invaginates into the distal bowel, producing infarction and gangrene of the inner bowel:
    • >80% involve the ileocecal region.
  • Often occurs with a pathologic lead point in children >2 yr:
    • Hypertrophied lymphoid patches may be present in infants.
    • Children >2 yr: 1/3 of patients have pathologic lead point.
    • Children >6 yr: Lymphoma is the most common lead point.
    • Adults usually have a pathologic lead point.
  • The most common cause of intestinal obstruction within the 1st 2 yr of life
  • Epidemiology in US:
    • Most frequently between 5 and 9 mo of age
    • Incidence is 2.4 cases per 1,000 live births.
    • Male > female predominance of 2:1
    • Mortality <1%
  • Morbidity increases with delayed diagnosis.
ALERT

Patients, particularly those in the pediatric age group, with a picture of potential intestinal obstruction, especially with hematest-positive stool or altered mental status, need to have intussusception considered.

ETIOLOGY
  • Most cases (85%) have no apparent underlying pathology.
  • Predisposing conditions that create a lead point for invagination, esp. in older children and adults:
    • Masses/tumors:
      • Lymphoma
      • Lipoma
      • Polyp
      • Hypertrophied lymphoid patches
      • Meckel diverticulum
    • Infection:
      • Adenovirus or rotavirus infection
      • Parasites
    • Foreign body
    • Henoch–Schönlein purpura
    • Celiac disease and cystic fibrosis (small intestine intussusception)
DIAGNOSIS
SIGNS AND SYMPTOMS
History
  • Classic triad (present in <50% of patients):
    • Abdominal pain
    • Vomiting, often bilious
    • Stools have blood and mucus (“currant jelly” stools)
  • Recurrent painful episodes accompanied by pallor and drawing up of the legs; intermittent fits of sudden intense pain with screaming and flexion of legs:
    • Occur in 5–20 min intervals
  • Mental status changes:
    • Irritability
    • Lethargy or listlessness; child can be limp or have a rag doll appearance.
    • May precede abdominal findings.
  • Stool variable:
    • Heme-positive (occult), bloody, or “currant jelly”
  • Preceding illness several days or weeks prior to the onset of abdominal pain:
    • Diarrhea
    • Viral syndrome
    • Henoch–Schönlein purpura
  • Recurrent intussusception occurs in <10% of patients.
