Effect of using pump on postoperative pleural effusion in the patients that underwent CABG

Insights
Off-pump coronary artery bypass grafting (CABG) may reduce the risk of left pleural effusion compared to on-pump CABG. This study found a statistically significant decrease in left pleural effusion in patients undergoing the off-pump procedure.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Medical Devices
Background:
- Coronary artery bypass grafting (CABG) is a common surgical procedure.
- Postoperative pleural effusion is a known complication.
- Comparing on-pump and off-pump CABG techniques is crucial for optimizing patient outcomes.
Purpose of the Study:
- To investigate the effect of on-pump versus off-pump coronary artery bypass grafting on the incidence of postoperative pleural effusion.
- To determine if surgical technique influences the occurrence of specific types of pleural effusion.
Main Methods:
- A cohort of 256 patients undergoing isolated CABG surgery was studied.
- Patients were divided into two groups: on-pump CABG using a heart-lung machine and off-pump CABG using stabilization devices.
- Data on postoperative pleural effusion (right, left, and bilateral) were collected and analyzed.
Main Results:
- While right and bilateral pleural effusion showed a higher incidence in the on-pump group, the difference was not statistically significant.
- Left pleural effusion was significantly less prevalent in the off-pump CABG group (P=0.006).
Conclusions:
- Off-pump coronary artery bypass grafting is associated with a lower incidence of left pleural effusion compared to on-pump CABG.
- Surgical technique may play a role in the development of specific pleural effusions post-CABG.
Objective:
The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting.
Methods:
A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden) heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11.
Results:
The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump) as compared to Group 2 (off-pump). But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893), P>0.05 for bilateral pleural effusion (P=0.780)]. Left pleural effusion was encountered to be lower in Group 2 (off-pump). The difference was found to be statistically significant (P<0.05, P=0.006).
Conclusion:
Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
