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.

Introduction: Complications following Cardiopulmonary resuscitation (CPR) are rare and usually follows a vigorous CPR or in special cases like pregnancy are due to lack of knowledge and clinical practice of how to preform CPR in pregnancy. One of this complication is diaphragmatic rupture with herniation of abdominal organs. Surgical intervention needs to be planned carefully in multidisciplinary team approach and requires fine surgical techniques for better outcome. There are few reported cases of diaphragmatic rupture after Cardiopulmonary resuscitation but none in pregnant woman. Case presentation: We report a rare case of diaphragmatic rupture in a 29-year-old pregnant patient who experienced a full-blown diaphragmatic defect and herniation of the abdominal organs into the thoracic cavity, as a complication of CPR. Following careful assessment and diagnosis, the patient underwent urgent laparotomy with reduction of the contents and primary closure of the defect. One year follow up was satisfactory. To the best of our knowledge, this is the first reported case of diaphragmatic rupture with herniation of the abdominal organs following CPR in a pregnant woman in the literature. Conclusion: The application of external cardiac massage through CPR is a life-saving procedure for the management of cardiac arrest. Common complications related to CPR include rib fractures, sternal fractures and haemothorax. Diaphragmatic rupture with herniation of the abdominal organs is a rare complication, having been reported only once in the literature (Sabzi F, Faraji R, Tanaffos 16:170-172, 2017); however, it represents a serious and life-threating event. Thus, careful evaluation of the patient by a multidisciplinary team and prompt intervention is recommended in order to improve outcomes.

BackgroundIdiopathic pulmonary artery aneurysm is a rare anomaly with only a handful reports in the literature. It is often asymptomatic, while the first presentation could be severe hemoptysis or death.Surgical intervention needs to be planned carefully with a multidisciplinary team approach to secure optimal outcome. We hope to spread our experience with such cases and to encourage other surgeons worldwide to deal surgically with these cases when its indicated.Case presentationA 47 years old man presented to our institution after three episodes of hemoptysis, echo demonstrated good left ventricle (LV) systolic function, normal right ventricle (RV) size and function, Chest computed tomography (CT) revealed aneurysmal dilatation with pending rupture of the pulmonary artery trunk (4.5 cm), the left pulmonary artery (6 cm) and the right pulmonary artery (2.3 cm). The patient successfully underwent replacement of Pulmonary artery trunk, left pulmonary artery and right pulmonary artery by Wovex Prosthetic graft (28 mm). The patient discharged home on the eight postoperative day in good clinical condition .ConclusionWith this case report we wish to emphasize the need for a careful multidisciplinary approach given the complex and rare nature of the reported pathology.Electronic supplementary materialThe online version of this article (10.1186/s13019-018-0791-9) contains supplementary material, which is available to authorized users.
