Introduction: Radial cannulation is needed in perioperative management of many patients requiring invasive hemodynamic monitoring during surgery and may be not only time consuming and at times difficult to attain in untrained centers.
Objectives: Comparative evaluation of safety and efficacy of Radial Arterial Cannulation using Conventional blind palpation technique with Ultrasound guided Technique perioperatively – Raccuet Study.
Materials and Methods: This randomized controlled, prospective, single blind comparative study was conducted on 142 adult ASA I to IV patients of either sex, scheduled for elective major surgery requiring general anesthesia of which 71 patients underwent radial cannulation by classical palpatory method (group P) and the other 71 underwent radial cannulation under ultrasound guidance (Group U). All procedures were evaluated using Siemens Acuson X500 ultrasound machine with 5-13Hz linear array transducer. All patients were evaluated for efficacy by measuring time to cannulation (TTC), mean time to first attempt cannulation (mTFA), and number of attempts for cannulation (NA). Safety was assessed by evaluating incidence of hematoma and spasm in both the groups. Statistical analysis was done using (SPSS) Version 22.0. Independent t test and Mann Whitney test have been used for carrying out significant P value.
Results: Patients were demographically similar in both the groups. TTC in group U (37.97±18.14sec) was significantly less than that in Group P (58.38±21.45sec) (P =0.007).mTFA was 34.81±15.77 seconds in group U compared with 55.58±19.29 seconds with group P (P=0.01). There was trend towards lower NA in group U as compared to group P (P=0.06).Incidence of hematoma formation and vasospasm were similar amongst both groups but study was underpowered to evaluate the same.
Conclusion: Ultrasound guided radial artery cannulation improves the success rate of cannulation in lesser time with similar complication rates as compared to classical palpatory method of cannulation.
