SUMMARY  Background: in our country, there are no studies on critical care or anesthesia that analyze the usefulness of ultrasound guidance for central venous catheterization. Objective: to compare the degree of difficulty of central venous line (CVL) placement with or without ultrasound guidance and the incidence of complications and to determine whether the level of training of the operator or the neck anatomy affects the results. Methods: there were studied 257 patients, classified according to the experience of the operator: "experienced=E" (over 70 central accesses carried out before trial) and "non-experienced =NE". Group "E" performed 152 venous accesses and group "NE" 105. All patients who required CVL in the CCE and operation room of the HCFFAA as from the beginning of the trial were included. Procedures were randomized as per "without ultrasound=Wo/U" (80-"E" and 54-"NE") and "with ultrasound=W/U" (72-"E" and 51-"NE"). Results: there were more correct placements of CVLs in group "E" than in group "NE" (88% vs.79%; p 0.04). There were also more correct placements in group "W/U" than in group "Wo/U" (91% vs. 78%; p=0.005). No significant difference existed in correct placement related to the type of neck (p=0.06). General incidence of complications was 11.7%. There is no difference between groups "W/U" (8.1%) and "Wo/U" (14.9%); p=0.09. However, when comparing groups "E" and "NE", the second group presented advantages in terms of reduction of complications using ultrasound guidance: 7.8% W/U vs. 24% Wo/U (p=0.03).
