Abstract
Introduction
The frequency of surgical procedures has increased steadily in recent decades,
including the myocardial revascularization.
Objectives
To demonstrate the importance of physiotherapy in the preoperative period of
cardiac surgery in relation to the reduction of hospital stay, changes in lung
volumes and respiratory muscle strength.
Methods
We conducted a prospective study with patients undergoing myocardial
revascularization, the Hospital das Clínicas da Universidade Estadual Paulista
(UNESP)/Botucatu - SP. We evaluated 70 patients of both genders, aged between 40
and 75 years, subdivided into two groups: group I - 35 patients of both genders,
who received a written protocol guidance, breathing exercises and respiratory
muscle training in the preoperative period and group II - 35 patients of both
genders, who received only orientation of the ward on the day of surgery. This
study was approved by the Ethics Committee of UNESP / Botucatu - SP.
Results
Maximal inspiratory pressure in third postoperative day and fifth postoperative
day and significant difference between groups, being better for the intervention
group. Expiratory pressure was significant in fifth postoperative day in the
intervention group compared to controls. The difference of length of hospital stay
in the postoperative was found between the groups with shorter hospital stay in
the group receiving preoperative therapy.
Conclusion
Physical therapy plays an important role in the preoperative period, so that
individuals in the intervention group more readily restored the parameters
evaluated before surgery, in addition, there was a decrease in the time of the
postoperative hospital stay. Thus, it is thought the cost-effectiveness of a
program of preoperative physiotherapy.
