Adult Subarachnoid Haemorrhage
Pathway and Care Bundle
Introduction
Early aggressive treatment of patients with a poor grade Subarachnoid
Haemorrhage has resulted in favourable outcomes1.
The aim of this paper therefore is to provide consistency across the North
Wales Network region for Critical Care patients with a spontaneous
Subarachnoid Haemorrhage (SAH).
Because there are some differences in the management of spontaneous
SAH patients from those with a Severe Brain Injury it was considered
‘safer’ to document their care separately. As with the Severe Brain Injury
pathway however this document includes a referral pathway, ICU
maintenance care and repatriation process for all SAH patients from the
three hospitals, much of it being very similar.
The first section provides a pathway and checklist for referral of the
Subarachnoid Haemorrhage patient to the Walton Neurological Centre.
This pathway has been agreed by Intensivists in North Wales with
colleagues at the Walton Centre.
The second section includes the guidelines that underpin the Subarachnoid
Haemorrhage Care Bundle. This should be utilised for all Subarachnoid
Haemorrhage patients who remain in the local ICUs. A quick guide of
these more detailed guidelines is also included.
The final section is a pathway for repatriating patients back to the local
ICUs from Walton.

Subarachnoid Haemorrhage (SAH) Care Bundle
(for adult patients requiring Critical Care)
Background Information
Nontraumatic spontaneous SAH usually is the result of a ruptured cerebral
aneurysm or arteriovenous malformation (AVM). Blood extravasation into the
subarachnoid space has a detrimental effect on both local and global brain function
and leads to significant morbidity and mortality.
Although mortality rates of SAH have decreased, it remains a devastating
neurological problem. An estimated 15% of patients die before reaching hospital.
Approximately 25% of patients die within 24 hours, with or without medical
attention. The mortality rate at the end of one week approaches 40%. Half of all
patients die in the first 6 months.
Recent developments in neurocritical care including enhanced monitoring
techniques, normalisation of pathophysiological states and better recognition and
management of complications following subarachnoid haemorrhage have improved
the level of care for SAH patients1. As a result mortality has decreased2,3. Advanced
age, worse clinical grade, rebleeding, larger aneurysm size, global cerebral
oedema, delayed cerebral ischaemia and medical complications all have a
detrimental impact on outcome after SAH4-6. Reports of early and aggressive
treatment of poor grade patients demonstrated unexpected improvements of long
term functional outcome7-9.
SAH is classified according to 5 grades:
Glasgow Coma Score

Grade I: Mild headache with or without meningeal irritation
15



Grade II: Severe headache and a no focal deficit
Grade III: Severe headache with focal neurological deficit
Grade IV: Depressed level of consciousness with or without
focal deficit
Grade V: Unconscious patient

World Federation of Neurological Surgeons.
The ICUs in North Wales are familiar with the concept of care bundles; therefore a
care bundle is described below to assist in the management of the subarachnoid
haemorrhage patients who remain in the local ICUs.
Subarachnoid Haemorrhage Care Bundle
Early neurological and cardiopulmonary resuscitation of poor grade patients
followed by high quality and comprehensive critical care should be the standard and
based on a team approach1. This Subarachnoid Haemorrhage care bundle therefore
aims to optimise care for the individual patient by addressing possible secondary
cerebral insults and limiting ongoing brain damage.
The three elements are:
1. Control of Intracranial Pressure (ICP) (caused by hydrocephalus and
global cerebral oedema).
2. Optimisation of cerebral perfusion and oxygenation.
3. Prevention of aneurysm rebleeding; control of blood pressure, seizure
prophylaxis.
It should be noted that in order to be compliant with the elements in this bundle
some elements of the Ventilator bundle may need to be excluded e.g. transfusion

guidelines and low tidal volume.
Bundle Element 1
Control of Intracranial Pressure (ICP)
In acute SAH the sudden rise in ICP up to the levels of MAP leads to an arrest of
cerebral circulation which is clinically seen as loss of consciousness and to the
development of global cerebral oedema. Cerebral oedema and the resultant
cerebral hypermetabolism are linked to increased risk of death, disability and
cognitive dysfunction4. Altered level of consciousness may also be related to
haematoma formation, hydrocephalus, vasospasm, or reduced cerebral blood flow.
Early detection of deterioration in the patient's neurological condition is essential for
the prompt treatment of complications such as vasospasm, rebleeding and/or
hydrocephalus.
Patients with a SAH therefore require frequent neurological observations. Pupil size
and reaction are paramount in the sedated ICU patient where sedation will prevent
motor responses. If ‘deep’ painful stimuli are required this should be performed
with supra-orbital pressure or trapezius squeeze10.
Additional measures to prevent increases in ICP are also indicated;
a. Perform Neurological Observations
 ½ hourly for 12 hours, hourly for 24 hours, then 2 hourly thereafter10
 Clinician discretion will be needed after the acute phase.
b. Avoid venous congestion
 head tilt 20-300 (preferably 300 but be mindful of compromising MAP and
thus cerebral perfusion pressure)
 avoid external compression; use adhesive ETT tapes or loose tapes)
 avoid high thoracic pressures (adhere to bowel protocol).
c. Control agitation / maintain adequate analgesia and sedation if
intubated
 analgesia and sedation (local protocol)
 (if required) muscle relaxant with neuromuscular monitoring
Bundle Element 2
Optimisation of cerebral perfusion and oxygenation
There is often an imbalance in cerebral oxygen delivery and cerebral oxygen
consumption resulting in tissue hypoxia11. A labile BP is common in high-grade
subarachnoid hemorrhage. Hypotension must be avoided at all costs as it will cause
a reduction in cerebral blow flow and will result in cerebral ischaemia12. Both
hypoxia and ischaemia will increase ICP.
Myocardial injury in patients with SAH occurs as a result of excessive sympathetic
drive and catecholamine release. ECG abnormalities occur in approximately 35% of
patients and a similar percentage of patients will also have an elevation of
Troponin. Echocardiographic wall motion abnormalities occur in about 25% of
patients.
Significant pulmonary complications occur in approximately 20% of patients and
this spectrum ranges from acute lung injury to pulmonary oedema. This may

complicate clinical management when trying to ensure adequate intravascular
volume on one hand and trying to avoid pulmonary oedema on the other13.
Cerebral vasospasm is a devastating medical complication of aneurysmal SAH that
is associated with high morbidity and mortality rates. It is most likely to develop 312 days post SAH, lasting approximately two weeks and occurs in about two thirds
of SAH patients, of which half will develop symptomatic cerebral ischaemia causing
neurological deficit of varying severity. Cerebral vasospasm may also lead to
increased ICP, secondary to infarction.
Fever (>380C) is a frequent event in SAH patients and is associated with
symptomatic vasospasm14 and an increased ICU and hospital length of stay15.
Administration of oral Nimodipine improves outcome after SAH16. The oral (or NG)
route has been shown to be just as effective as intravenous administration, but is
associated with less hypotension.
d. Nimodipine administration
 Administer Nimodipine to all SAH patients; 60mg orally every 4 hours,
continued for 21days. If enteral route is not possible, consider IV infusion
via CVP as per the British National Formulary; 0.02% (neat from vial into
50ml syringe) at 5-10mls/hr. NB use giving set supplied with the vial.
Adequate cerebral oxygen delivery depends primarily on satisfactory cardiorespiratory performance, but can further be categorised by those aspects which
need to be in place before transfer of oxygen from haemoglobin to the tissues
occurs, namely;
e. an adequate circulating volume
Aim for:
 capillary refill <2 seconds
 CVP minimum 8mmHg1 using isotonic crystalloids 0.9% NaCl at 1.0-1.5
mls/kg/hr.
 consider hypertonic saline where hyponatraemia present (consider
cerebral salt wasting)
 if u/o >4mls/kg consider treatment for Diabetes Insipidus
NB: If problems with fluid or sodium balance advice from neuro-critical care Intensivist at ICU
(Walton) can be sought 24hrs/day.
f. adequate perfusion pressure
Aim for:
 Systolic <160mmHg1, diastolic <110mmHg1
 MAP >80mmHg
o adequate filling (as above)
 Vasopressors as necessary12
 Antihypertensives as necessary1
g. adequate oxygenation
Aim for:
 SaO2 >93%
 pO2 >13kPa10,17
h. avoid hyperaemia
Aim for:



i. control pyrexia
 maintain normothermia <370C1

(NB: Every 10C increase in core temperature causes a 6-10% increase in cerebral
blood flow. The increase in cerebral blood flow causes an increase in cerebral
blood volume therefore contributing to an increase in ICP).
j. control hyperglycaemia
 maintain blood glucose 6-10mmol-1

(NB: Avoid hypoglycaemia at all costs)
Bundle Element 3
Prevention of rebleeding; control of blood pressure, seizure prophylaxis.
Rebleeding, a major complication, carries a mortality rate of 51-80%. It is hard to
predict which patients will suffer a rebleed, yet it may happen at any time. After the
first 24 hours have passed, rebleeding risk remains around 40% over the
subsequent four weeks, suggesting that interventions should be aimed at reducing
this risk as soon as possible.
The main aim of treatment for SAH is prevention of rebleeding while preventing
secondary ischaemia.
Prolonged seizures may result in hypoxaemia and cerebral infarction due to cerebral
hypoxia
k. control of blood pressure (see also f – adequate perfusion pressure)
 Systolic <160mmHg1, diastolic <110mmHg1
o adequate filling (as above) see above note
 Vasopressors as necessary12
 Antihypertensives as necessary1
l. control fitting
 Consider the context and requirement for induction of anaesthesia /
intubation and ventilation
 If clinically indicated – Phenytoin 20mg/kg IV bolus followed by 5mg/kg
daily1 (adjust dose according to plasma levels corrected for serum
albumin); not exceeding 1.5 grams in 24hrs.
m. Pharmacological thromboprophylaxis is generally contraindicated until the
aneurysm is secured.
 Use
Summary
As well as optimising care of the SAH patient this care bundle should facilitate audit
of process. Although compliance is expected, especially where deviations from this
agreed practice cannot be justified, the bundle is not designed to replace clinician
judgment.

Rationale
Pupillary reactions will provide prognostic information.
Prompt detection of changes in size, shape and/or reaction
of pupils any indicate swelling/an expanding lesion and
increasing ICP.
Head elevation will reduce oedema (and thus ICP) but >300
may reduce MAP and therefore CPP.
Head rotation and neck flexion can increase ICP by impeding
cerebral venous drainage.
Tight ETT tapes will impede venous return.
Straining will increase abdominal and thoracic pressures.
Avoid ‘clustering’ care – stagger interventions giving time for
ICP to settle in between.
Sedation will help dampen the effect of any stimuli that might
increase ICP.
NB Beware of hypotensive effects of sedation, especially boluses.

Pathway.
Maintenance of cerebral perfusion pressure (the variable
which defines the pressure gradient driving cerebral blood
flow) can be achieved with fluid replacement and inotropes
(see below).
Hyponatraemia occurs in 20-40% SAH patients as result of
the syndrome of inappropriate excretion of anti-diuretic
hormone (SIADH).
Hypotension will result in a reduction in cerebral blood flow

For every 10C increase in temperature there is a 10-13%
increase in metabolic rate. Therefore pyrexia will exacerbate
ischaemia. Shivering markedly increases ICP
Hyperglycaemia may worsen cerebral ischaemia by
decreasing cerebral blood flow.
NB Beware of hypoglycaemia – the injured brain cannot tolerate it
A labile BP is common in high-grade SAH. Hypertension
increases the risk of re-bleeding however hypotension must
be avoided at all costs as it causes a reduction in cerebral
blow flow resulting in cerebral ischaemia.
Patient does
not require
antiepileptics.
Terminal care
Seizure activity may cause rebleeding. It may also cause
secondary brain injury as a result of increased metabolic
demands, raised ICP and excess neurotransmitter release.
Steps taken to reduce the
risk of re-bleeding?
Are all patients with SAH
 Normotensive
 Adequate control of
fitting (where
necessary)
Or is there an attempt to
achieve these parameters?
