Key result
Two-day preoperative incentive spirometry cuts postoperative pulmonary complications by ~43% in open heart surgery.
Why the study?
To determine the effect of preoperative use of an incentive spirometer on preventing postoperative pulmonary complications among patients undergoing open heart surgeries.
Does preoperative incentive spirometer training reduce postoperative pulmonary complications in patients undergoing open heart surgeries?
RCT (n=64)
Single-blinded
Simple randomization (flipping a coin)
Yes
Does preoperative incentive spirometer training reduce postoperative pulmonary complications in patients undergoing open heart surgeries?
Preoperative incentive spirometry training for two days before open heart surgery reduces postoperative pulmonary complications and shortens ICU and hospital length of stay.

Supports preoperative incentive spirometer training before open heart surgery; extends RCT evidence for reducing postoperative pulmonary complications.
Objectives: To determine the effect preoperative use of an Incentive Spirometer (IS) has on preventing postoperative pulmonary complications among patients undergoing open heart surgeries. Methods: A prospective, randomized, controlled single-blinded parallel-group design. Data were collected from January 9th 2022 to April 1st 2022. A total of n = 64 eligible patients were equally randomized to either intervention or control group. Patients in the intervention group performed preoperative IS training for two days before the scheduled surgery. The primary endpoint was the incidence of in-hospital PPCs. The secondary endpoints were postoperative Peak Expiratory Flow Rate (PEFR), Intensive Care Unit (ICU) stay, Hospital Length of Stay (HLOS). Results: Patients in the intervention group had a lower incidence of postoperative pulmonary complications compared to the control group (12.5% and 21.8%). There was a statistical significant difference between the two groups regarding postoperative PEFR, HLOS and intensive care unit stay. Conclusions: Preoperative rehabilitation (involving incentive spirometer is related to a lower incidence of postoperative pulmonary complications for the group that received the intervention. Training with preoperative incentive spirometer resulted in a shortening of hospital length of stay and Intensive Care Unit (ICU) stay.

Faleh et al. (2022) conducted an RCT in Open heart surgery (CABG or valve procedures) (n=64). Preoperative Incentive Spirometer training vs. Standard care (no preoperative incentive spirometer training) was evaluated on Incidence of in-hospital postoperative pulmonary complications (PPCs). Preoperative training with an incentive spirometer for two days reduced the incidence of postoperative pulmonary complications to 12.5% compared to 21.8% in the control group among patients undergoing open heart surgery.
