About

The purpose of this study is to evaluate the use of preoperative incentive spirometry (IS) as an aid to improve postoperative lung function. The hypothesis is that application of a standardized protocol of preoperative respiratory care teaching and exercise will improve lung performance that will subsequently result in prevention of postoperative pulmonary complications and that increasing the duration of preoperative use better improves lung mechanics postoperatively. The investigators propose to compare a patient population that uses IS as currently prescribed in the routine course of care (only to be familiar with preoperatively, but use postoperatively) against a population that uses IS with a standardized regimen for at least 3 days prior to the operation in terms of preoperative IS volumes, intraoperative pulmonary mechanics, postoperative IS volumes, and incidence of postoperative pulmonary complications.

Trial design

Primary purpose: Treatment

Allocation: Non-Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

---

50 participants in 2 patient groups, including a placebo group

Control group

Placebo Comparator group

Description:

Patients assigned to the control group were educated on the proper technique of using the incentive spirometer and were instructed to use it for 3 breaths once per day to become able to use the device properly and consistently.

Treatment:

Procedure: Incentive Spirometry

Experimental Group

Experimental group

Description:

Patients assigned to the experimental group were instructed to use the spirometer by inhaling as slowly and deeply as possible in a set of 10 times and to repeat the process at least 5 times every day until the day of surgery.

Treatment:

Procedure: Incentive Spirometry
