Study Objective:
The objective of this study was to demonstrate the safety and utility of a method of percutaneous access for cannulation of adult patients for venovenous extracorporeal life support (ECLS).
Design:
A retrospective review of a patient series.
Setting:
A surgical ICU at a university teaching hospital.
Patients:
The study group consisted of 94 adults > 17 years old with respiratory failure who were placed on venovenous ECLS by means of percutaneous cannulation.
Interventions:
The cannulation of the internal jugular and femoral veins (FVs) using the Seldinger technique for venovenous ECLS.
Measurements And Results:
Between May 1992 and November 1997, we performed percutaneous cannulation for venovenous ECLS in 94 adult patients with respiratory failure. The mean (+/- SD) age was 36.1+/-12.7 years old (range, 17 to 65 years). The mean (+/-SD) weight was 80.7+/-22.3 kg (range, 36 to 156 kg). The right internal jugular vein (RIJV) was used for venous drainage access in all but four cases. The right FV (n = 86), the left FV (n = 3), or the RIJV (n = 4) was utilized for venous reinfusion. The maximum blood flow (+/-SD) during ECLS was 57.6+/-17.5 mL/kg/min (range, 22.4 to 127.8 mL/kg/min), with a postmembrane outlet pressure (+/-SD) of 146+/-43 mm Hg (range, 56 to 258 mm Hg) at the maximum flow rate. There were 11 unsuccessful percutaneous cannulation attempts. In three patients (3%), the complications consisted of arterial injury requiring operative cutdown and repair. In six patients (6%), cannula-site bleeding required pursestring suture reinforcement of the cannula site. One patient died from the perforation of the superior vena cava during cannulation.
Conclusions:
Based on these data, we conclude that percutaneous cannulation may be utilized to provide venovenous ECLS in adults.
