Manual Inline Stabilization

img_1635

Demonstration of MILS or Manual In-Line Stabilization.

– maintain head in neutral position

– assistant to intubation stands by patient as shown above, with hand on either side of head between mastoid process and the occipital

– assistant holds head steady while opposing the applied forces of airway manipulation (gently)

This technique is used for patients with suspected cervical spine injuries. A jaw-thrust maneuver should be used instead of head-tilt/chin lift maneuver. Do not use cricoid pressure. Use of video laryngoscopes may be necessary.

PATCH Trial

Platelet transfusion versus standard care after acute stroke due to spontaneous cerebral haemorrhage associated with antiplatelet therapy (PATCH)

Research Question:  Will platelet transfusion compared to standard of care reduce death or dependence in patients who present with ICH who took antiplatelet drugs within 7 days?

NOTES:

  • multicenter, open-label, randomized trial
  • 60 hospitals in Netherlands, UK and france
  • Inclusion: supratentorial ICH, antiplatelets for 7 days, GCS at least 8
  • standard of care vs standard of care + platelet transfusion within 90 minutes of CT scan
  • primary outcome: shift towards death or dependence on mRS at 3 months

Results:

  • 190 participants (97 treatment, 93% standard of care)
  • death or dependence at 3 months:  adjusted OR 2.05 95% CI 1.18-3.56; p=0.0114
  • serious adverse event:  42% vs 29%
  • deaths during hospital stay:  29% vs 24%

Anticoagulation in Patients with Brain Metastases

Treatment:

  • Anticoagulate in patients with brain tumors and VTE except if risk of ICH is high: i.e.
    • melanoma mets
    • renal cell carcinoma mets
    • choriocarcinoma mets
    • thyroid carcinoma mets
  • treat x 3-6 months; long term if malignant gliomas
  • LMWH recommended versus warfarin
  • If risk of ICH high:
    • IVC filter if significant residual brain mets
    • if mets already removed / treated effectively and medical condition too unstable – anticoagulate

DVT Prophylaxis:

  • do not anticoagulate except in post-operative period
  • use SCDs with post-op LMWH or UFH 12-24 hours after surgery
  • cotninue prophylaxis until ambulation resumed

SETScore for Early Tracheostomy in Stroke

Capture

**APS acute physiology score, LIS lung injury score

 

  • initially an in-house screening tool for tracheostomy prediction
  • performed within 1st 24 hours after admission – use worst value in the first 24 hours
  • Dysphagia either
    • reported from a transferring neurological department or
    • observed by clinical signs on admission
      • non-successful swallowing test
      • impaired saliva handling
      • loss/reduction of gag reflex
    • if already intubated on admission, scored with “0”
  • (Neuro)surgical intervention
    • decompressive surgery, hematoma removal, non-cranial major surgery
    • NOTE EVD or probe placement, thrombectomy, angioplasty for vasospasm or coiling
  • Diffuse lesion = a multilocular or widespread affection of brain (i.e. SAH, brain edema, multiple infarcts, hematomas)
  • hydrocephalus = distension of ventricles requiring EVD
  • total sum ranges between 3 and 37

Previously used (with score of >10) to screen for eligibility to be included in pilot trial of SETPOINT study for early tracheostomy (within 3 days) to standard regimen (late tracheostomy between day7 and day14).
