Bleeding, Body Mass Index, CABG, Re-exploration


Objectives: To determine the frequency of re-exploration due to excessive bleeding in post-operative coronary artery bypass graft patients at a tertiary care hospital in Karachi.

To compare the frequency of re-exploration with body mass index in postoperative coronary artery bypass graft patients at a tertiary care hospital in Karachi

Study design and setting: A descriptive cross-sectional study was carried out at the Cardiac Surgery Unit, NICVD, Karachi, Pakistan, during the period Oct: 2022 to Dec 2023.

Materials and Methods: All participants who fulfilled the inclusion criteria and attended NICVD, Karachi, were included in the study. After outlining the protocol, risks, and advantages of the study, informed written consent was attained. All patient in our study was sent to a specialized intensive care unit (ICU). and kept under close observation during their post-surgery hospital stay, and re-exploration due to bleeding was recorded. Data was collected in Proform, and the SPSS-18 version was applied for analysis.

Results: Patients' ages varied from 30 to 70 years old, with a median age of 55. In the distribution of gender, 151 (75.1%) were male, while 50 (24.9%) were female. Re-exploration was found in 8 (4%) patients, whereas in comparison, re-exploration was noted in 5 (2.5%) vs. 3 (1.5%) patients between body mass index 19--30 vs. >30 kg/m2 patients, with a non-significant P-value (P = 0.432).

Conclusion: In conclusion, the low rate of re-exploration was noted due to excessive bleeding in post-operative coronary artery bypass surgery.

Patients with non-significant differences in body mass index. It is advised that further extensive research be done to validate the present findings.
