Abstract

Context: Central venous catheterization (CVC) is integral part of management in modern era. Studies have compared different approaches of Ultrasound guided CVC with number of variables, but still inconclusive. Aims: Comparing ultrasound guided CVC techniques, short vs oblique axis, for novice ultrasound operator in terms of successful cannulation (SC), venous access time (VAT), attempts, cannulation time (CT) and complications. Methods and Material: Study includes 60 patients >18 years, requiring CVC, undergoing surgery under general anaesthesia. A single anaesthetist who is novice to both, short and oblique, approaches of ultrasound guided CVC, performed cannulation. Statistical analysis used: SPSS17.0 version used. Student’s T test and Mann Whitney U test used for continuous variables. Nominal categorical data compared using Chi-square and Fisher’s exact test. P<0.05 considered statistically significant. Results: Demography and clinical characteristics were comparable. SC in S group (93.33%) was found to be comparable to ‘O’ group (86.66 %). In ‘S’ and ‘O’ groups VAT was 46.78+/-17.91 and 54.65+/-15.87 respectively. In group S, like group O, only 2 cases required >3 attempts for IJV cannulation. CT in both groups (123.64+/-44.03 in S group and 124.63+/-40.8 in O group) was comparable. Complication rate was higher in ‘O’ (13.3%) vs ‘S’ group (3.3%), but it was statically insignificant. Conclusions: Short and long axis approaches of ultrasound guided IJV catheterization are comparable in terms of SC, attempts, VAT, CT and complications.
