Background Postoperative pulmonary complications (PPCs) often occur after cardiac operations and are a leading cause of morbidity, inhibit oxygenation, and increase hospital length of stay and mortality. Although clinical evidence for PPCs prevention is often unclear and crucial, measures occur to reduce PPCs. One device usually used for this reason is incentive spirometry (IS). The aim of the study is to evaluate the effect of preoperative incentive spirometry to prevent postoperative pulmonary complications, improve postoperative oxygenation, and decrease hospital stay following coronary artery bypass graft (CABG) surgery patients. Methods This was a clinical randomized prospective study. A total of 80 patients were selected as candidates for CABG at An-Najah National University Hospital, Nablus-Palestine. Patients had been randomly assigned into two groups: incentive spirometry group (IS), SI performed before surgery (study group) and control group, preoperative spirometry was not performed. The 40 patients in each group received the same protocol of anesthesia and ventilation in the operating room. Result The study findings showed a significant difference between the IS and control groups in the incidence of postoperative atelectasis. There were 8 patients (20.0%) in IS group and 17 patients (42.5%) in the control group (p = 0.03). Mechanical ventilation duration was significantly less in IS group. The median was four hours versus six hours in the control group (p < 0.001). Hospital length of stay was significantly less in IS group, and the median was six days versus seven days in the control group (p < 0.001). The median of the amount of arterial blood oxygen and oxygen saturation was significantly improved in the IS group (p < 0.005). Conclusion Preoperative incentive spirometry for two days along with the exercise of deep breathing, encouraged coughing, and early ambulation following CABG are in connection with prevention and decreased incidence of atelectasis, hospital stay, mechanical ventilation duration and improved postoperative oxygenation with better pain control. A difference that can be considered both significant and clinically relevant. Trial registration Thai Clinical Trials Registry: TCTR20201020005.

Background Pain is a major obstacle and one of the main reasons people seek medical attention and is a frequent stressor for many clients in the intensive care unit (ICU). However, clients should not be left complaining, especially when solutions are available; each patient has the right to assess and manage their pain in the best way possible. Therefore, the objective of this study was to analyze nurses' knowledge, attitudes, and practice (KAPs) regarding pain management in Palestinian ICU settings and to determine the possible obstacles that may hinder effective and competent pain management for critically ill clients. Methods This cross-sectional research was conducted online through social media. An approved questionnaire was used to assess KAPs and obstacles in pain treatment approaches for critically ill patients. Bloom’s cutoff points for adequate practice, appropriate knowledge, and a positive attitude were applied. IBM SPSS Statistics for Windows, Version 21.0 was used for analyses. Results One hundred ninety-one nurses were approached, the majority of the participants in this investigation were males (n = 127, 66.5%), and the mean age of the study participant was 29 ± 7 (year). The overall knowledge score was 15, measured for median knowledge = 7 with an interquartile range (IQR) of 4–8, and higher scores indicate more knowledge about the management and control of pain. The total attitude score = 11, the median = 6, with an IQR of 5–7. The reluctance to prescribe opioids was 79.6%, the lack of proficiency in pain management knowledge was 78.5%, and rigorous controls over opioid use were 77.5%, which was the lion's share of commonly recognized hurdles. The overall practice score was 10, with a median of 5.0 with an IQR of 3.0 to 6.0, and nurses revealed that they would evaluate all the steps involved in pain management in each round they have. Conclusions This research reveals a knowledge, attitude, and practice gap among the working nurses. Therefore, adequate and efficient plans must be aimed at ICU nurses to foster the level of knowledge and direct attitudes toward pain control through applicable interventional programs.
