GUIDELINES FOR HIGH RISK PROCEDURES WHEN
DEALING WITH HIGH RISK PATIENTS
PREAMBLE:
During certain high-risk procedures that generate droplets and aerosols, health
care workers may be exposed to a very high burden of respiratory secretions. Highrisk procedures include, but are not limited to the following:
- administration of aerosolized/nebulized therapy
- Intubation/extubation
- Bag-valve mask ventilation
- Tracheostomy
- Chest tube insertion
- Cardio/pulmonary arrest (may include any of the above procedures)
- bronchoscopy
- non-invasive ventilation (CPAP, BiPAP)
- needle thoracotomy/open thoracotomy thoracostomy
High risk procedures should be avoided whenever possible. However, in situations
where they become necessary (e.g. intubation of a patient in respiratory distress),
staff must follow the additional level of precautions outlined in this policy and
procedure.
Areas where high-risk procedures on high-risk patients may be performed include:
a) Emergency Department
b) ICU
c) Rooms in which patients are placed on Droplet and/or Airborne Precautions
d) OR
High-Risk patients include:
Patients - with an infectious respiratory disease (e.g. TB, probable or suspect
SARS, or patient under investigation for SARS)
- who develop new onset of symptoms (unexplained cough, unexplained
high fever, hypoxia, shortness of breath or difficulty breathing)
- with Congestive Heart Failure with/without concurrent pneumonia
- with Exacerbation of COPD
- with Exacerbation of Asthma
- with pulmonary infiltrates and presumptive diagnosis
(not SARS)
Patients transferred - from a (SARS) Level 2 hospital
- from a (SARS) Level 3 hospital

PROCEDURE:
2.1
FOR ALL NON-SARS PATIENTS:
Personal Protective Equipment
i)
For emergency endotracheal intubation of patients, each patient
unit will have:
-
a manual resuscitation bag with bacterial/viral filter
in-line suction catheters
intubation equipment, and
full protective apparel (see ii below) for the individual
performing the intubation, and for all other individuals in
the room.
ii)
All individuals involved in performing high risk procedures
(intubation, cardiopulmonary resuscitation interventions
bronchoscopy etc.) will wear full protective apparel.
This includes an N95 mask, a gown, gloves, eye protection
(goggles), and full-face/head protection (full face
Shield).
iii)
Protective apparel will be removed carefully at the
end of the procedure to reduce the risk of contamination
and reaerosolization of droplets (see Appendix IV).
Note:
 Suctioning may be performed in the normal fashion in small
children.
Procedures
i)
ii)
Nebulized therapies should be avoided. Respiratory medications
will be delivered using the metered dose inhaler and
aerochamber, when possible.
The need for chest physiotherapy must be carefully assessed;
recognizing that cough-inducing procedures may increase the
risk of transmission.
GUIDELINES FOR HIGH RISK PROCEDURES WHEN
DEALING WITH PATIENTS IN CRITICAL CARE AREAS
PAGE 4 OF 8
Procedures (con't)
iii)
Oxygen will be delivered DRY avoiding nebulized humidity.
Maximum flow rate for nasal prongs will be 6 litres per minute.
iv)
If a patient requires up to 50% oxygen by mask, use a ventimask.
v)
If a patient required more than 50% oxygen, then the respiratory
therapist (RT) must be notified. The nebulizer system will be
emptied of the water from the prefilled water bottle. The water
bottle will remain DRY. The RT will monitor and wean the
patient to nasal prongs as soon as the patient can tolerate this.
vi)
Patients will receive frequent mouth care.
vii)
Patients with tracheostomies will be provided with humidity.
viii) Patients who require oxygen greater than 50% must be referred
to RT for set up and ongoing monitoring.
ix)
Non-invasive ventilation (CPAP/BiPAP) should be avoided. If
ventilation is essential for the patient, the patient will be
screened in consultation with the physician and infection
control to ensure that a diagnosis of SARS has been ruled out.
The procedure will be performed in a private room, when at all
possible (Note: in ER, BiPAP will continue to be done in the
trauma room with curtains closed, for patients diagnosed with
Congestive Heart Failure )
Note:
 Children may receive nebulized therapy if MDI is not deemed to be
appropriated. Full protective apparel must be worn by all persons
in the room.
 For children, oxygen should be humidified as usual.
2.2
FOR SARS PATIENTS:
See Appendix III for Protected Code Blue (sudden cardiorespiratory
arrest in SARS patients)
1.
Aerosol-generating and/or cough inducing procedures may be
performed on patients who may have SARS only when deemed
absolutely necessary by the attending physician and documented by
him/her in the patient's chart.
2.
The following procedures should not be performed on a routine basis
on known, suspected or R/O SARS patients.
a. Bronchoscopy
b. Sputum induction
c. Aerosol theapy (includes O2 aerosol and medicated aerosol)
d. Non-invasive CPAP or BiPAP

expiratory circuit will be used. If this is not possible, such a filter will
be placed in the expiratory circuit of the ventilator
Filters will be changed when fluid build-up impedes ventilation (at
least every 24 hours)
Disposal of filters will be considered a high-risk exposure and staff
must protect themselves using full personal protective equipment
following the maximal precautions
Filters and respiratory circuits for known SARS cases must be single
use and disposed of after use.
Filters are to be bagged, sealed and then placed in a biohazardous bag
for disposal.

Appendix III
Protected Code Blue
To prevent the spread of communicable respiratory diseases to Health Care
Workers, SARS precautions are essential and include eye protection (face shield
and goggles), N95 mask, double gown and double gloves. However, in certain
high-risk situations, such as cardiorespiratory failure requiring airway
management, these may not be sufficient and a "Protected Code Blue" will be
called.
The Protected Code Blue (PCB) Team is an in-hospital team which consists of
designated individuals, at least one of whom is highly skilled in intubation and
resuscitation measures:
1. Physician (staff emergologist, Intensivist, Anaesthetist)
2. RT
3. RN from ICU
4. RN from ER
A number of PCB Teams (consisting of 4 individuals in each team) will be
established by the hospital. Members who are physicians will be selected by the
Chiefs of the Emergency, Family Practice and Surgery Departments. Members
who are RNs will be designated by the Nurse Manager of the ICU/ER. All
Respiratory Therapists will be on the PCB Team.
All designated Protected Code Blue Team members will receive special training
(provided by the hospital initially and on an annual basis) and are expected to
consistently adhere to skills and attend opportunities to maintain skills.
A Protected Code Blue Team will be available in hospital 24/7 during times of
serious regional outbreaks such as SARS, or if a patient is admitted with a known
high risk communicable respiratory disease.
During outbreaks with potential for large numbers of patients, the core PCB
Teams will train staff in high risk areas such as emergency, ICU and affected
medical and surgical units and operating room staff to assist in the PCB.
Ideally, such patients should be placed in the hospital rooms with negative
pressure, but may arrive unexpectedly in the emergency department in need of
life saving care after being transported by family or paramedics. Each of these
situations poses significant risk to all involved and has the potential to rapidly
spread the disease.
The following procedures must be adhered to:
1. Equipment
 ER, ICU, Medical, Surgical and SARS Unit must have crash carts which
include:
i.
Manual resuscitation bag with bacterial/viral filter
ii.
In-line suction catheters
iii.
Personal Protective System (PPS) or Positive Airway Pressure Respirator
(PAPR)
2. Preparation:
 Consider early ICU transfer or preferably transfer to another facility when
deteriorating (50% O2 necessary)
 Consider early controlled intubation when patient's respiratory status
deteriorates
 Keep all non-essential staff outside room
 All team members and unit staff must have completed fit test for N95 mask
 All staff involved with intubation procedures will have completed training
for application and removal of PPS or PAPR
 All staff involved with a PCB will be familiar with the "Protected Code Blue"

If resuscitation is successful, a member of the PCB Team must remain with
the patient until transfer to another area of the hospital or to another hospital
if possible. If there is a prolonged delay in moving the patient, this Team
member must have back-up. Precautions for patient movement such as plastic
tent over stretcher, etc. will be at the discretion of the PCB Team.
Consideration should be given to termination of resuscitative attempts at the
time survival is deemed to be futile (e.g. unwitnessed arrest, asystole) as
outcome of resuscitation is inversely proportional to the length of time of
resuscitation, and the risk to the providers increases.

May 13 & May 16, 2003.
Protected Code Blue
There are numerous infection control concerns that arise during acute
resuscitation of patients, especially those under SARS precautions. Resuscitation
requires performance of high-risk procedures (airway management - intubation,
chest tube insertion etc) Time needed to put on additional personal protective
equipment may introduce delays in response. The need to provide best care for
the patient must be integrated with the need to protect health care workers.
To prevent the spread of communicable respiratory diseases to Health Care
Workers, additional personal protective equipment is required to be worn while
performing high-risk procedures on high risk patients. SARS precautions are
essential and include eye protection (face shield and goggles), N95 mask, double
gown and double gloves. However, in certain high risk situations, such as
cardiorespiratory failure requiring airway management, these may not be
sufficient and a Protected Code Blue Team will be called.
(PCB) Team is an in-hospital team which consists of designated individuals, at
least one of whom is highly skilled in intubation and resuscitation measures:
5. Physician (staff emergologist, Intensivist, Anaesthetist)
6. RT
7. RN from ICU
8. RN from ER
A number of PCB Teams (consisting of 4 individuals in each team) will be
established by the hospital. Members who are physicians will be selected by the
Chiefs of the Emergency, Family Practice and Surgery Departments. Members
who are RNs will be designated by the Nurse Manager of the ICU/ER. All
Respiratory Therapists will be on the PCB Team.
All designated Protected Code Blue Team members will receive special training
(provided by the hospital initially and on an annual basis) and are expected to
consistently adhere to skills and attend opportunities to maintain skills.
A Protected Code Blue Team will be available in hospital 24/7 during times of
serious regional outbreaks such as SARS, or if a patient is admitted with a known
high risk communicable respiratory disease.
During outbreaks with potential for large numbers of patients, the core PCB
