Lung Function before and Two Days after Open-Heart Surgery

Abstract

Reduced lung volumes and atelectasis are common after open-heart surgery, and pronounced restrictive lung volume impairment has been found. The aim of this study was to investigate factors influencing lung volumes on the second postoperative day. Open-heart surgery patients (n = 107, 68 yrs, 80% male) performed spirometry both before surgery and on the second postoperative day. The factors influencing postoperative lung volumes and decrease in lung volumes were investigated with univariate and multivariate analyses. Associations between pain (measured by numeric rating scale) and decrease in postoperative lung volumes were calculated with Spearman rank correlation test. Lung volumes decreased by 50% and were less than 40% of the predictive values postoperatively. Patients with BMI >25 had lower postoperative inspiratory capacity (IC) (33 ± 14% pred.) than normal-weight patients (39 ± 15% pred.), (P = 0.04). More pain during mobilisation was associated with higher decreases in postoperative lung volumes (VC: r = 0.33, P = 0.001; FEV1: r = 0.35, P ≤ 0.0001; IC: r = 0.25, P = 0.01). Patients with high BMI are a risk group for decreased postoperative lung volumes and should therefore receive extra attention during postoperative care. As pain is related to a larger decrease in postoperative lung volumes, optimal pain relief for the patients should be identified.

Physiotherapy following cardiac surgery: Program comparison

“…Screening techniques are being searched that would anticipate the length of stay in hospital and a 5-metre walking test has been offered [19]. Good results and reduced complications are demonstrated by programs that started before the operation and continue in the postoperative period [20,21]. Similar to our study, the highest number of complications is on the first three POD, the most common complications -respiratory, hemodynamic and cardiac conduction disorders [5,6,22].…”

Effect of Breathing Exercises on Quality of Recovery Among Postoperative Patients

“…Postoperative patient usually have different manifestation that affect their postoperative recovery including physical, psychological, emotional and pain. Utilization of breathing exercises during postoperative period is mainly reduced the stated manifestation and improve postoperative outcomes, those findings were supported by different studies including (Shashi and Rakesh, 2017, E. WESTERDAHL, 2015, E. Westerdahl and M. Fagevik, 2014, Urell, et al, 2012. Therefore, the researchers of the present study evaluates the effect of breathing exercises on quality of recovery among post-operative patients.…”

The effects of positive airway pressure ventilation during cardiopulmonary bypass on pulmonary function following open heart surgery

“…Open-heart surgeries and CPB alter the pulmonary function and cause multiple complications that varied from microscopic atelectasis to acute respiratory distress syndrome. Post-operative atelectasis is a common complication that different factors are responsible for its incidence ( 4 ). In an anesthetized patient, the lung tissue is compressed due to diaphragm relaxation and its upside movement ( 5 ).…”
