“…The use of prophylactic respiratory interventions in the early postoperative stage is consistent with physiotherapy service provision in other countries and expert consensus (Hanekom et al, 2012;Patman et al, 2017), despite the necessity for DB&C interventions remaining contentious across different major surgical groups (Pasquina, Tramèr, & Walder, 2003;Reeve et al, 2010), including those undergoing UAS (Mackay, Ellis, & Johnston, 2005;Pasquina, Tramèr, Granier, & Walzer, 2006;Silva, Li, & Rickard, 2013). For example, in patients undergoing UAS, two studies (Mackay et al, 2005;Silva et al, 2013) have demonstrated that the addition of deep breathing exercises to physiotherapy-directed early (POD1) postoperative ambulation does not further reduce PPCs compared with early postoperative ambulation alone. This suggests that early postoperative ambulation on POD1 may be all that is necessary in low-risk patients, and that the routine use of prophylactic DB&C may not be justified.…”
