The effects of expiratory muscle training after colorectal surgery

Abstract

The strength of expiratory muscles have great importance in improving cough quality and clearing secretions. The aim of this study was to analyze the effects of expiratory muscle training (EMT) in addition to conventional chest physiotherapy after colorectal surgery.

24 individuals (13 m) were included into the study after colorectal surgery. The individuals were divided into two groups (mean age group 1 61.75±7.4, group 2 56.42±12.5 years) randomly. The individuals in group 1 (n=12) received expiratory muscle training in addition to conventional chest physiotherapy (CCP), in the group 2 (n=12) deep breathing exercises with incentive spirometry (IS) in addition to CCP were performed (6 times a day and 5 days a week for both group) in the postoperative period. The treatment continued until discharge. Maksimum inspiratory and ekspiratory pressure (P_imax–P_emax), functional capacity (6MWT), the level of movement and independence (patient and observer mobility scale), postoperatif pulmonary complications (PPC) (Melbourne group scale version 2) was evaluated. The length of stay at hospital (LSH) was also recorded.

P_imax–P_emax decreased significantly after surgery, increased in both groups in pre-discharge period (p<0.05) but no difference was found between the groups (p=0.82, p=0.83 respectively). Functional capacity decreased in both groups, did not reach preoperative level and there was no difference between the groups (p=0.45). PPC were not observed in any patients and LSH was similar between groups (p=0.66).

IS and EMT improved respiratory muscle strength in patients undergoing colorectal surgery, had no side effects and could be easily used in the clinic as an alternative.
