Abstract

Objective

This study aims To compare the outcome of Subxiphoid and Left lateral intercostal drains in terms of pain score, ventilation time, duration of ICU and hospital stay, and the occurrence of atelectasis and pleural effusion in patients after Coronary artery bypass graft CABG.


Place & Duration of Study

Department of Cardiac Surgery, Armed Forces Institute of Cardiology-National Institute of Heart Diseases, Rawalpindi. The duration of the research was from January 2021 to March 2022.


Methodology

A total number of 180 patients in this study scheduled for an elective on-pump CABG were randomized into two groups. Group 1 (G -1 90 patients with sub-xiphoid drain placement) and group 2 (G-2 90 patients with lateral intercostal drain placement). Baseline data were noted, including age, sex, smoking history, diabetes mellitus and hypertension, and preoperative ejection fraction. Pre-operatively, informed consent was taken from all patients included in the study. Each patient was briefed about the surgical procedure, the post-op care plans, and the visual analog scale (VAS) for pain assessment. Post-operatively, data was collected for pain at 24 hours, the number of ventilation hours, ICU-stay hours, Hospital-Stay Days, Chest Drain Output, and development of pleural effusion or atelectasis. These parameters were compared for both groups.


Results

A total of 180 patients undergoing coronary artery bypass grafting were included in the study. The mean age of the participants was 56.4±9.02 years. The mean VAS score of the participants was 5.89±1.66, and it was significantly higher in the lateral intercostal drain group. The frequency of atelectasis was also higher in the lateral intercostal group. There was no statistically significant difference in mechanical ventilation, ICU stay, and hospital stay days.


Conclusion

There is no significant difference between the two methods of drain insertions when it comes to ventilation time, hospital, and ICU stay. However, the pain score and atelectasis are significantly higher in the intercoastal group. More studies need to be conducted to broaden the validation of our results.
