| Summary: | Introduction: Surgical procedures in abdominal area lead to
changes in pulmonary function, respiratory mechanics and
impaired physical capacity leading to postoperative pulmonary
complications, which can affect up to 80% of upper abdominal
surgery.
Aim: To evaluate the effects of flow and volume incentive spirometry on pulmonary function and exercise tolerance in patients
undergoing open abdominal surgery.
Materials and Methods: A randomized clinical trial was
conducted in a hospital of Mangalore city in Southern India.
Thirty-seven males and thirteen females who were undergoing
abdominal surgeries were included and allocated into flow and
volume incentive spirometry groups by block randomization.
All subjects underwent evaluations of pulmonary function with
measurement of Forced Vital Capacity (FVC), Forced Expiratory
Volume in the first second (FEV1), Peak Expiratory Flow (PEF).
Preoperative and postoperative measurements were taken up
to day 5 for both groups. Exercise tolerance measured by SixMinute Walk Test during preoperative period and measured again
at the time of discharge for both groups. Pulmonary function was
analysed by post-hoc analysis and carried out using Bonferroni’s
‘t’-test. Exercise tolerance was analysed by Paired ‘T’-test.
Results: Pulmonary function (FVC, FEV1, and PEFR) was found
to be significantly decreased in 1st, 2nd and 3rd postoperative
day when compared with preoperative day. On 4th and 5th
postoperative day the pulmonary function (FVC, FEV1, and
PEFR) was found to be better preserved in both flow and volume
incentive spirometry groups. The Six-Minute Walk Test showed
a statistically significant improvement in pulmonary function on
the day of discharge than in the preoperative period. In terms
of distance covered, the volume- incentive spirometry group
showed a greater statistically significant improvement from the
preoperative period to the time of discharge than was exhibited
by the flow incentive spirometry group.
Conclusion: Flow and volume incentive spirometry can be safely
recommended to patients undergoing open abdominal surgery
as there have been no adverse events recorded. Also, these
led to a demonstrable improvement in pulmonary function and
exercise tolerance. |
