Abstract
Introduction: Continuous infusion (CI) of clotting factor concentrate has facilitated surgical procedures and intensive replacement therapy in hemophilia patients. The advantage of CI over bolus infusions is ability to maintain steady-state levels of coagulation factors and moreover, to reduce the total amount of factor concentrate spent. CI is commonly delivered through a peripheral vein. However, a significant number of hemophilia patients have distorted peripheral veins which can compromise continuous flow of factor concentrate needed for successful treatment. Also, thrombophlebitis at the site of venous access, an adverse effect of CI previously reported, can further impair the delivery of factor concentrate in CI and make the future use of the vein for concentrate administration impossible or difficult. Use of central venous catheter can ease the application of CI. By searching the literature, we found only a few case reports describing the use of temporary non-tunneled central venous catheters (CVC) for administrating CI in patients with hemophilia.
The aim of this study was to evaluate the efficacy and safety of short-term used non-tunneled CVC for CI during surgical procedures in hemophilia patients.
Methods: In this study we have retrospectively studied patients with hemophilia that had temporarily used non-tunneled CVC for CI of factor concentrate during and after major surgery in the Saint-Luc University Hospital in Brussels between August 2000 and April 2014. The indication for CVC usage was a major surgery with anticipated need for CI of factor concentrate longer than 5 days.
CVC was inserted by an experienced anesthesiologist in the operating room after the induction of general anesthesia and normalization of APTT. Before the CVC insertion, the patient would have already received bolus of clotting factor concentrate and have the CI started through the peripheral vein. Upon placement, the CI was switched to the CVC. The CVC was kept in place until leaving hospital or cessation of the need for continuous infusion.
Results: During the study period, 40 male patients with hemophilia A or B (37 and 3 patients, respectively) underwent 67 major surgical procedures covered by CI of factor concentrate delivered through CVC. Patients, age 21 -81, had severe, mild or moderate disease (33, 5 and 2 patients, respectively). Patients had altogether 65 CVC for 67 surgical procedures. The same catheter was used for 3 surgeries and 16 patients had CVC placed more than once; 14 patients twice, one patient three times and one ten times. Patients underwent orthopedic surgery (79%), gastrointestinal surgery (15%) and cardiovascular surgery (5%) while one patient (1%) had surgery of urinary tract. The CVC were placed in the right jugular vein (58%), the left jugular vein (18%), the left subclavian vein (8%) and right subclavian vein (3%), while the data were missing in 6 patients. Median duration of catheter was 12 days, with range from 5 to 107 days. No CVC was removed prematurely and no malfunctions of catheters were recorded. Moreover, no complications related to the CVC were noted whatsoever. We searched for bleeding at the site of puncture of the catheter, signs of local infection, pneumothorax following placement of CVC, catheter thrombosis, malfunction of the catheter and surgical site infection. Finally, most of the patients reported satisfaction related to the use of CVC for CI of factor concentrate.
Conclusions: Based on results of this study, we can conclude that the use of short-term non-tunneled CVC should be considered in patients with hemophilia undergoing major surgery with the need for prolonged CI of factor concentrates. By placing CVC we can ensure undisturbed flow of factor concentrate during CI and preserve peripheral veins for the future concentrate administration.
