ABSTRACT:
Objective: To investigate the effectiveness of ultrasound-guided central venous
catheterization when compared to the conventional procedure. Method: A
prospective cohort study was carried out over a 9-month period from February
to October 2016 involving 144 inpatients at PICU of Irmandade da Santa
Casa de Sao Paulo Hospital, undergoing central venous catheterization. The
patients were matched in pairs of identical patients according to the levels of
potentially intervening variables (age, nutritional status, puncture site, professional
experience), differing only as to the CVC technique: ultrasound-guided
(USG-CVC) or conventional (C-CVC). Discarding data from non-paired patients,
the remaining did forming 47 pairs, matched as two related samples:
USG-CVC and C-CVC groups. Success parameters: number of puncture attempts;
time spent at CVC; success rate and complications. Results: In the
USG-CVC group, the number of attempts (mean = 2.04) and the time spent at
catheterization (mean = 11.89 minutes) were lower (t = 2.34, df = 46, t 0.95 =
2.02, p t = 3.07, df = 46, t 0.95 = 2.02, p F (1, 46) = 16.6; Q (1) = 12.5, p F (1, 46) = 3.76; Q (1) = 3.56, p > 0.05) when considering several attempts.
Complications were found less frequently in the USG-CVC group
(3/47) than in the CVC-C (13/47), (F (1, 46) = 8.24; Q (1) = 7.14, p
