The AARC reviewed a total of 54 clinical trials and
systemic reviews on incentive spirometry and updated the following
recommendations based on the assessment, development, and evaluation (GRADE) scoring
system. 1: Incentive spirometry alone is not recommended for routine alone use
in the preoperative and postoperative setting to prevent postoperative
pulmonary complications. 2: It is recommended that incentive spirometry be used
with deep breathing techniques, directed coughing, early mobilization, and
optimal analgesia to prevent postoperative pulmonary complications. 3: It is
suggested that deep breathing exercises provide the same benefit as incentive
spirometry in the preoperative and postoperative setting to prevent
postoperative pulmonary complications. 4: Routine use of incentive spirometry
to prevent atelectasis in patients after upper-abdominal surgery is not
recommended. 5: Routine use of incentive spirometry to prevent atelectasis
after coronary artery bypass graft surgery is not recommended. 6: It is
suggested that a volume-oriented device be selected as an incentive spirometry
device. Respir Care2011;56(10):1600 –1604. © 2011 Daedalus Enterprises]
Preoperative and postoperative incentive
spirometery is aimed to prevent atelectasis, pneumonia, and to improve the
airway. Upper abdominal surgery has the most complications with preoperative
and post-operative respiratory problems. The incentive Spirometer cannot be used alone with this type of post operative care because it will be ineffective. The incentive spirometer prevents
complications by decreasing pleural pressure, promoting increased lung
expansion and better gas exchange. There is lacking evidence for exactly how
frequent the incentive spirometer should be used, although some suggestions
have been made in clinical trials such as: Ten breaths every one to two hours
while awake, Ten breaths 5 times a day, Fifteen breaths every four hours.
Assessment of the outcome shows that correct use of the incentive spirometer Decreases respiratory rate, Absence of fever, Normal
pulse rate, Improvement in previously absent or diminished breath sounds,
Improved radiographic findings, Improved arterial oxygenation (PaO2, SaO2, SpO2), reduced FIO2 requirement. In conclusion,
incentive spirometery shows ineffective after abdominal surgery and coronary
artery bypass surgery when used alone. When the incentive spirometer is indicated, it must be
included with deep breathing excercises, directed coughing, early ambulation,
and optimal analgesia to be affective in lowering the incidence of pulmonary
complications.
