The incidence of phlebitis has proved to be a menace in effective care of surgical patients, delaying their recovery and increasing duration of hospital stay and cost. The recommendations for reducing its incidence and severity have been varied and of questionable efficacy. The current study was undertaken to evaluate whether elective change of IV cannula at fixed intervals can have any impact on incidence or severity of phlebitis in surgical patients. All patients admitted to the Department of Surgery, SMIMS undergoing IV cannula insertion, fulfilling the selection criteria and willing to participate in the study, were segregated into two random groups prospectively： Group A wherein cannula was changed electively after 24 hours into a fresh vein preferably on the other upper limb and Group B wherein IV caunula was changed only on development of phlebitis or leak i.e. need-based change. The material/brand and protocol for insertion of IV cannula were standardised for all patients, including skin preparation, insertion, fixation and removal. After carmulation, assessment was made after 6 hours, 12 hours and every 24 hours thereafter at all venepuncture sites. VIP and VAS scales were used to record phlebitis and pain respectively. Upon analysis, though there was a lower VIP score in group A compared to group B （0.89 vs. 1.32）, this difference was not statistically significant （p-value = 0.277）. Furthermore, the differences in pain, as assessed by VAS, at the site of puncture and along the vein were statistically insignificant （p-value 〉 0.05）. Our results are in contradiction to few other studies which recommend a policy of routine change of carmula. Further we advocate a close and thorough monitoring of the venepuncture site and the length of vein immediately distal to the puncture site, as well as a meticulous standardized protocol for IV access.展开更多

This patient was introduced with a 17G cannula in the basilic vein of the dorsal venous arch of the left hand prior to knee replacement surgery. Post knee surgery patients use walking aids for mobilization. Cannula which has been placed at the dorsum of the hand has a potential to bend at the neck of the cannula when the wrist bend while holding the walking aid. Repeated bending can result in fatigue fracture of the cannula neck. In this patient at the time of cannula removal, it was noted the catheter part is broken and proximal migration. Ultrasound guided localization was done and removed with a venotomy under local anesthesia. It is advisable to place peripheral venous cannulas well away from the wrist joint, which will prevent catheter bending and fracture. This is a very important point to consider when placing cannulas in orthopaedic patients who undergo surgical procedures.展开更多
