Superior vena cava drainage during thoracoscopic cardiac surgery: bilateral internal jugular vein sheaths versus one percutaneous superior vena cava cannula.

ABSTRACT

OBJECTIVE: To evaluate bilateral internal jugular vein sheaths as a replacement of one percutaneous superior vena cava cannula for superior vena cava drainage during thoracoscopic cardiac surgery. DESIGN: A prospective and randomized study. SETTING: Single cardiovascular institute. PARTICIPANTS: Adults undergoing thoracoscopic cardiac surgery. INTERVENTIONS: Patients were randomized into a percutaneous superior vena cava cannula group and a bilateral internal jugular vein sheaths group. The superior vena cava drainage for cardiopulmonary bypass was performed with one percutaneous superior vena cava cannula (14-18 Fr) or the bilateral internal jugular vein sheaths (8 Fr). MEASUREMENTS AND MAIN RESULTS: Both interventions reached theoretic flow rate in all patients. In patients weighing<50 kg (n=38) and 50-70 kg (n=64), the average central venous pressure values during cardiopulmonary bypass of both groups showed no significant differences. The patients weighing>70 kg (n=15) in the bilateral internal jugular vein sheaths group had a normal average central venous pressure value, but it was significantly higher than that of percutaneous superior vena cava cannula group ([10.5±3.1] mmHg vs. [4.5±4.4] mmHg, p=0.013). The patient satisfaction scale scores for the cervical incisions were significantly higher in the bilateral internal jugular vein sheaths group than in the percutaneous superior vena cava cannula group ([2.6±0.9] vs. [2.1±0.8], p=0.002). CONCLUSIONS: The bilateral internal jugular vein sheaths were a feasible and effective option to replace one percutaneous superior vena cava cannula during thoracoscopic cardiac surgery, with better patient satisfaction.
