part 1
physiotherapy for surgical patients
what abdominal regions do you need to know
liver
appendix
stomach
spleen
pancreas
small intestine
large intestine
ureter
kidneys
bladder
gall bladder
which thoracic organs/ structures do you need to know
ribs
trachea
pericardium
base of heart
right lung
left lung
diaphragm
apex of heart
what is a sternotomy
Incision made along the midline of the thorax through the sternum
Allows access to the heart and lungs
Used for cardiac procedures and some lung surgery
Often quite painful for the patient
what are the precautions associated with a sternotomy
Precautions will vary surgeon to surgeon – no consensus
Generally,….
For 4-12 weeks post-op:
No pushing through arms (including sit -> stand)
No pulling (including banister upstairs, dog on lead)
No lifting heavy weights (e.g. nothing heavier than a kettle)
Some may restrict arm movements (e.g. overhead, behind back, unilateral movements vs bilateral movements)
what is Functional residual Capacity
Functional residual capacity (FRC) is the volume remaining in the lungs after normal passive expiration (FRC= ERV + RV)
General anaesthesia decreases FRC (positional and diaphragm/intercostal relaxation)
Alteration in FRC can result in small airway closure and V/Q mismatch, and lead to ongoing post op respiratory complications
The volume of gas in the lungs at the end of normal expiration is the functional residual capacity (FRC), approximately 3000ml in a 70kg man.
ERV = Expiratory Reserve Volume, the volume that can be forcibly expired at the end of normal expirationRV = Residual Volume, the volume left in the lungs at the end of maximal expiration
what is Atelectasis
Atelectasis,the collapse of part or all of a lung, is caused by a blockage of the air passages (bronchus orbronchioles) or by pressure on the lung. Risk factors for atelectasis include anaesthesia, prolonged bed rest with few changes in position, shallow breathing and underlying lung disease
what are some respiratory complications post surgery
Patients with Post-op Pulmonary Complications (PPCs):
1 in 5 die within 30 days of major surgery (0.2-3% without)
Mortality rate at 1 year 45.9% (8.7% without)
Mortality rate at 5 years 71.4% (41.1% without)
Length of hospital stay (LOS) has been shown to be prolonged by 13–17 days
what are the risk factors of pre-op
age, lung disease, heart failure, neurological disorder, functional status, obesity, smoking
what are the peri-op risk factors
mechanical ventilation, anaesthesia, opioids, emergency surgery, length of surgery, lung deflation, surgical site
what are the post-op risk factors
pain, reduced mobility, dehydration, altered mental state, recumbancy
What problems may post op patients have that we can address?
Atelectasis
Sputum retention
Decreased mobility
what are some key respiratory physiotherapy problems
Dyspnoea (breathlessness)
Secretion retention
Loss of lung volume
Respiratory Failure
what are the aims of post-op physiotherapy management
Improve V/Q matching
Restore FRC
Maintain sputum clearance
Restore Mobility
what are some considerations for post op Ax
Consider morphine, impact of this on resp drive
Prioritize
Seek wider sources of information
Closed questions/prioritized information gathering
Hand placement/positioning
Consent
what are some respiratory physio options
Positioning
Mobilise
ACBT (splinted cough)
Humidification
Incentive spirometry
Intermittent Positive Pressure Breathing (IPPB)
CPAP
Suctioning
what are some positioning tips
Avoid slumping, encourage high sitting
Patients are encouraged to sit out of bed as soon as possible
Positioning can re-expand atelectatic lung, but regular position change is needed to prevent atelectasis reappearing in dependent zones
Clinical assessment and chest X-ray will assist in decision about positioning
(should be turning someone every 2 hours while in intensive care)
how does moving from supine to upright affect the body
Increase:
Tidal volume
Total lung capacity
Vital capacity
FRC
Residual volume
AP diameter of chest
Diaphragmatic excursion
Mobilisation of secretions
what should you consider when mobilising post op patients
Early post op mobilisation combines the advantages of an upright posture with a natural increase in tidal volume
↑ FRC
All post-op patients should be sat out of bed first day, if medically stable, and mobilised as soon as possible
These patients may have lots of attachments
You may need x2 x3 physios/assistants to help!!
Ensure pain is controlled (take pain killers,
Ensure the patient is cardiovascularly stable
MUST KNOW FOR OSPE
If patient can mobilise – must mobilise in OSPE, improves circulation, removes secretions, increase tidal volume (improve/increase independence), increase FRC, aid digestion
DON’T MOBILISE IF
HR above 100bpm
If they have atrial fibrilation
what is active cycle of breathing technique (ACBT)
The active cycle of breathing techniques (ACBT) is used to mobilise and clear excess secretions
The ACBT is very useful as it can be adapted to a wide variety of patient presentations
The technique comprises a cycle of:
Breathing control (as before)
Thoracic expansion exercises (TEEs) (deep breathing)
Forced expiration technique (FET) (huff)
what are some post op respiratory techniques
For the post-operative patient, the following manoeuvres may be added to the TEEs:
Inspiration is active and may be combined with a 3-second hold before the passive relaxed expiration
An additional increase in lung volume can be achieved by using a ‘sniff’ manoeuvre at the end of a deep inspiration
This aims to decrease atelectasis and restore lung volume
Once a patient has brought their secretions to the central airways, patients can either huff or cough with or without support
Patients can be taught to use a pillow or a towel to support their wound as many surgical patients are reluctant to cough due to pain or a fear that their stitches will burst
Can also use splinting for huffing
