Abstract
Objective:
Port sites are a common source of perioperative bleeding in robotic cardiac surgery, which can be exacerbated by patient anatomy and anticoagulation. We present results from the liberal usage of a balloon-tipped coudé catheter for tamponade of robotic port sites during robotic mitral surgery.
Methods:
All patients who underwent robotic mitral valve surgery at our institution from August 2016 to July 2022 were studied (N = 320). Patients converted to sternotomy were excluded (n = 5). Patients were then divided into 2 groups for before or after implementation of a protocol for the liberal use of balloon tamponade for patients with port site bleeding refractory to cautery. Catheter balloon tamponade was applied to a bleeding port site while weaning from cardiopulmonary bypass and usually removed after protamine administration. In rare cases of severe coagulopathy, the catheter was left inserted and removed in the intensive care unit after the coagulopathy resolved.
Results:
A total of 315 patients were divided into a pre-protocol group (“control,” n = 127) and a post-protocol group (“balloon,” n = 188). The balloon group showed lower rates of reoperation for bleeding (0% vs 4.7%, P = 0.004), lower rates of pacemaker insertion (0.5% vs 3.9%, P = 0.04), and higher rates of chest tube removal on the first postoperative day (83% vs 70%, P = 0.01). Postoperative and intraoperative transfusion rates as well as hospital length of stay were similar between groups.
Conclusions:
The liberal use of intraoperative balloon tamponade of robotic port sites may decrease the risk of bleeding complications in robotic mitral valve surgery.
