    Postcardiopulmonary bypass hemorrhage remains a serious complication of cardiac surgery. Given concerns regarding adverse effects of blood product transfusion and limited efficacy of current antifibrinolytics, procoagulant medications, including recombinant factor VIIa (rFVIIa) and factor eight inhibitor bypass activity (FEIBA), increasingly have been used in managing refractory bleeding. While effective, these medications are associated with thromboembolic complications. This study compared the efficacy and risk of adverse events of rFVIIa and FEIBA in cardiac surgical patients with refractory bleeding.This retrospective study evaluated 168 patients who underwent cardiac surgery and received either FEIBA or rFVIIa to manage postbypass hemorrhage. Demographic, clinical, and outcomes data were collected and statistical analysis performed to compare thromboembolic event rates, relative efficacy, and 30-day mortality following administration of these medications.Single university hospital.Patients undergoing cardiac surgery.None.Sixty-one patients received rFVIIa, and 107 received FEIBA. Demographics, surgical procedures, and preoperative anticoagulation were similar between the cohorts; however, the rFVIIa cohort had longer durations of cardiopulmonary bypass (305.1 v 243.8 min, p<0.01). There were no significant differences in the number of thromboembolic events, 30-day mortality, or rates of revision surgery. Neither group demonstrated a clear relationship between dosage and occurrence of thromboembolic events. The rFVIIa cohort received more platelets than the FEIBA cohort (3.13 v 1.67 units, p = 0.01), but transfusion rates of other blood products were similar.This study suggests that rFVIIa and FEIBA have similar efficacy and adverse event profiles in managing intractable postbypass hemorrhage in cardiac surgical patients. Further prospective studies are required.

  • A cost study of postoperative cell salvage in the setting of elective primary hip and knee arthroplasty TRANSFUSION Rao, V. K., Dyga, R., Bartels, C., Waters, J. H. 2012; 52 (8): 1750-1760


    The increasing costs, limited supply, and clinical risks associated with allogeneic blood transfusion have prompted investigation into autologous blood management strategies, such as postoperative red blood cell (RBC) salvage. This study provides a cost comparison of transfusing washed postoperatively salvaged RBCs using an orthopedic perioperative autotransfusion device (OrthoPat, Haemonetics Corporation) versus unwashed shed blood and banked allogeneic blood.Cell salvage data were retrospectively reviewed for a sample of 392 patients who underwent primary hip or knee arthroplasty. Mean unit costs were calculated for washed salvaged RBCs, equivalent units of unwashed shed blood, and therapeutically equivalent volumes of allogeneic RBCs.No initial capital investment was required for the establishment of the postoperative cell salvage program. For patients undergoing total knee arthroplasty (TKA), the mean unit costs for washed postoperatively salvaged cells, unwashed shed blood, and allogeneic banked blood were $758.80, $474.95, and $765.49, respectively. In patients undergoing total hip arthroplasty (THA), the mean unit costs for washed postoperatively salvaged cells, unwashed shed blood, and allogeneic banked blood were $1827.41, $1167.41, and $2609.44, respectively.This analysis suggests that transfusing washed postoperatively salvaged cells using the OrthoPat device is more costly than using unwashed shed blood in both THA and TKA. When compared to allogeneic transfusion, washed postoperatively salvaged cells carry a comparable cost in TKA, but potentially represent a significant savings in patients undergoing THA. Sensitivity analysis suggests that in the case of TKA, however, cost comparability exists within a narrow range of units collected and infused.

  • Recognition of local anesthetic maldistribution in axillary brachial plexus block guided by ultrasound and nerve stimulation JOURNAL OF CLINICAL ANESTHESIA Veneziano, G. C., Rao, V. K., Orebaugh, S. L. 2012; 24 (2): 141-144


    Nerve stimulation may occur despite the presence of a fascial barrier between the needle tip and the nerve, which may prevent appropriate flow or distribution of local anesthetic solution. During an axillary nerve block, ultrasound (US) guidance was used to identify the median nerve. Insertion of a needle with US and nerve stimulator guidance resulted in the appearance of the needle tip in contact with the nerve. However, as local anesthetic injection was begun, it was clear that the injectate was accumulating superficial to the investing fascia of the neurovascular bundle. No injectate was seen below the fascia. With US guidance, the needle was repositioned at a greater depth. Repeat injection of local anesthetic clearly flowed around the nerve.

  • Analysis of major complications associated with arterial catheterisation QUALITY & SAFETY IN HEALTH CARE Salmon, A. A., Galhotra, S., Rao, V., DeVita, M. A., Darby, J., Hilmi, I., SIMMONS, R. L. 2010; 19 (3): 208-212


    Arterial catheterisation is used for continuous haemodynamic monitoring in patients undergoing surgery and in critical care units. Although it is considered a safe procedure, a major complication such as arterial occlusion and limb gangrene can occur.To determine the incidence, outcome and potential to avoid complications associated with arterial catheterisation.The number of arterial catheterisation was determined using an anaesthesiology and critical care medicine billing database over a period of 4 years (1 January 2003 to 31 December 2006). Possible major complications were identified from two hospital databases; all identified charts were screened and then reviewed by an expert panel that determined causation. A major complication was defined as requiring operative intervention and/or resulting in permanent harm.15 (0.084%) major complications were identified among 17 840 instances of arterial catheterisation insertions. Of 15 arterial catheterisations, nine were performed in the operating room and six in the intensive care unit. Nine patients suffered ischaemic injury, which progressed to gangrene in three patients. Three patients developed haematoma that required surgical evacuation; two of these required vascular repair. One patient had compartment syndrome requiring fasciotomy and two patients had sheared catheter fragments that needed to be removed. All 15 patients had multiple comorbidities, and those in the operating room had an American Society of Anesthesiologists score of >or=3. Seven (46.6%) had arterial catheterisation done under emergent circumstances. Six (40%) died during hospitalisation because of complications unrelated to arterial catheterisation.Arterial catheterisation had a very low rate of major complications. They seem associated with high severity of illness and emergency surgery.
