Bedside orthopedic procedures.

Orthopedic bedside procedures commonly are performed and are appropriate. As the complexity of patient needs increases and resources are stretched, more patient care, including orthopedic procedures, will be performed in cost-effective but safe environments such as the monitored intensive care setting. Medical technology and expertise are expanding rapidly, and these improved resources can and will allow more procedures to be performed safely and effectively outside the operating room. The decision to perform a specific procedure on a specific patient in a specific environment requires careful consideration of the risk to benefit ratio. This consideration should involve the patient, the physicians, and the entire health care team.

Vascular complications associated with orthopedic procedures.

Damage to vascular structures during orthopedic procedures occurs relatively infrequently; when it does occur, however, recognition and prompt intervention are essential. We report herein 11 vascular injuries secondary to orthopedic procedures encountered between 1978 and 1988. Two injuries occurred as a consequence of lumbar laminectomy, three as a result of total hip replacement, three secondary to open reduction and internal fixation of a fracture of a lower extremity, two secondary to attempted closed reduction of humeral fractures and one injury as a result of hip flexion contracture release. Injury occurred to three iliac arteries, three popliteal arteries, two brachial arteries, one femoral artery, one graft to femoral anastomosis and two iliac veins. Five arterial injuries were repaired primarily, one with a vein patch, while five required bypass grafts. One venous injury was repaired primarily and the other required placement of a Greenfield filter for thrombosis. Major complications were a result of diagnostic delay and subsequent ischemia in most patients. There were no deaths. We conclude that vascular injuries can occur as a result of laceration, compression or traction during orthopedic procedures as a result of the proximity of vascular structures to the spine, joints and long bones. Also, we conclude that injuries manifest themselves primarily as hemorrhage or ischemia; that excellent results can be obtained with prompt recognition and treatment; that angiography is useful in those with mild ischemia in whom diagnosis is delayed, and that preoperative documentation of the vascular status of patients is critical prior to orthopedic procedures.

A randomized, controlled trial of i.v. versus i.m. ketamine for sedation of pediatric patients receiving emergency department orthopedic procedures.

STUDY OBJECTIVE: We compare adverse events, efficacy, and length of sedation of intravenous (i.v.) versus intramuscular (i.m.) ketamine procedural sedation and analgesia for orthopedic procedures in the emergency department (ED). METHODS: Pediatric patients receiving ketamine for orthopedic procedures were enrolled in a prospective, randomized, controlled trial in a children's hospital ED. All patients were initially randomized to receive ketamine either 1 mg/kg i.v. or 4 mg/kg i.m. Demographics, adverse events, sedation efficacy, and length of sedation were recorded. RESULTS: Two hundred twenty-five patients were randomized (116 i.v., 109 i.m.). Two hundred eight patients, aged 14 months to 15 years, completed the study, 109 i.v. and 99 i.m. Respiratory adverse events were similar between groups (i.v. 8.3% versus i.m. 4.0%; odds ratio [OR] 0.47; 95% confidence interval [CI] 0.14 to 1.6). Vomiting in the ED was more common in the i.m. group (26.3% versus 11.9%; OR 2.60; 95% CI 1.2 to 5.9). Using the Faces Pain Scale, patients in the i.m. group reported significantly less pain from the procedure. Video observers reported significantly lower distress in the i.m. group during the painful procedure (Observation Score of Behavioral Distress scores 0.35 i.m. versus 0.74 i.v.; mean difference 0.38; 95% CI 0.04 to 0.72). Length of sedation was significantly longer in the i.m. group (median 129 versus 80 minutes). Satisfaction of sedation was high in parents and physicians, with no difference in reported satisfaction between groups. This study was terminated early because of nursing resistance based on the longer recovery times observed in patients receiving ketamine i.m. CONCLUSION: In this study of pediatric sedation for orthopedic procedures, we found that ketamine 4 mg/kg i.m. was more effective than 1 mg/kg i.v. but demonstrated significantly longer recovery times and more vomiting.

No influence of large volume blood loss on serum vancomycin concentrations during orthopedic procedures.

We prospectively studied orthopedic patients with either large or small blood loss who also received vancomycin prophylaxis to determine the effect of intraoperative volume shifts on serum vancomycin concentrations. There were 6 index patients in the large blood loss group (greater than 2 L), and 7 in the control group (less than 2 L). Mean estimated blood loss for index and controls was 4.4 L and 1.0 L, respectively. Mean intraoperative fluid resuscitation, excluding blood products, was 12.4 L and 5.1 L, respectively. There was a modest inverse correlation between blood loss and intraoperative serum half-life of vancomycin. Although controls maintained slightly higher intraoperative vancomycin concentrations at each time-point, there was no statistically significant difference between the groups with regard to absolute concentrations or rate of decline. After 8 hours, the serum vancomycin concentration exceeded the MIC-90 for Staphylococcus aureus by approximately eightfold in all but one case patient. This was a morbidly obese patient with massive blood loss. Thus, blood loss during orthopedic procedures has minimal effects on intraoperative kinetics of vancomycin. Redosing is rarely indicated, although a preoperative 1.5 gram-dose should be considered for patients weighing more than 90 kg.

Pulmonary embolism after minor elective orthopedic procedure.

The occurrence of pulmonary embolism, in spite of thromboprophylaxis after a minor elective orthopedic surgery (release of m. rectus femoris tendon) is reported. In case of this severe complication, an early diagnosis is of outmost importance to enable optimal therapy introduction. Deep vein thrombosis and pulmonary embolism are frequent complications after total joint replacement, however, they may also develop after minor surgical orthopedic procedures. The possible causes of pulmonary embolism after release of m. rectus femoris tendon included the history of varicose veins and sclerozation of calf veins, and operative procedure with intraoperative pressure upon large veins of the iliofemoral region, which may and is expected to occur during this procedure. The importance of thrombopropylaxis in orthopedic surgical procedures is emphasized by this case presentation.

Vascular injuries associated with elective orthopedic procedures.

The objective of this study was to review the diagnosis, management, and outcome of the rare iatrogenic arterial injury associated with elective orthopedic joint procedures. A retrospective review was conducted of all patients presenting to the vascular surgery service with arterial injury after elective orthopedic procedures between 1997 and 2002. Clinical records were reviewed for presentation, type of injury, management, and outcome. During the study period, 20 patients having 21 total orthopedic procedures were identified with 27 arterial injuries. There were 4350 elective orthopedic procedures during this period for an incidence of 0.005%. There were 14 total knee arthroplasties, 4 total hip arthroplasties, and 3 ankle reconstructions in the study group. Presenting signs included acute ischemia with loss-of-limb Doppler-detected arterial flow/pulses (13 patients, 62%), intraoperative arterial bleeding (3 patients, 14%), nonhealing wounds (3 patients, 14%), and limb edema (2 patients, 10%); the diagnosis was delayed >24 hr in 5 patients (25%). Arterial thrombosis was the most common abnormality identified (21 of 27 injuries, 78%), followed by laceration/avulsion (3 injuries, 11%) and pseudoaneurysm development (3 patients, 11%), and involved the iliac ( n = 3), common femoral ( n = 2), profunda ( n = 1), superficial femoral ( n = 4), popliteal ( n = 12), or tibial ( n = 5) arteries. Concomitant popliteal venous injury was present in one patient. Injured arterial segments had preexisting atherosclerotic disease (33%) and 15 patients (71%) had prior surgery in proximity to the arterial injury while an additional 9 (43%) had prior traumatic injury (7 [78%] of whom had revision orthopedic surgery as well). Management consisted of vein bypass grafting ( n = 15, 56%), primary repair ( n = 3, 11%), and thrombectomy with thrombolysis ( n = 2, 7%). One patient (5%) underwent primary above-knee amputation. There was one death from septic shock and there were three limb losses (14%). Arterial injury associated with elective orthopedic joint surgery is more common during redoprocedures and in patients with preexisting atherosclerosis. Despite arterial repair/bypass, limb morbidity is common and related to preexisting occlusive disease or extent of arterial thrombosis.

Comparison of propofol/fentanyl versus ketamine/midazolam for brief orthopedic procedural sedation in a pediatric emergency department.

PURPOSE: To compare the effectiveness of 2 medication regimens, propofol/fentanyl (P/F) and ketamine/midazolam (K/M), for brief orthopedic emergency department procedural sedation. This study was powered to compare recovery times (RT) and procedural distress as measured by the Observational Score of Behavioral Distress-revised (OSBD-r; range: 0-23.5 with 23.5 representing maximal distress). METHODS: We conducted a prospective, partially-blinded controlled comparative trial comparing intravenous P/F with K/M in a convenience sample of 113 patients aged 3 to 18 years old undergoing orthopedic procedural sedation. All medications were administered by the intermittent intravenous bolus method. An independent sedation nurse recorded total sedation time and RT. Effectiveness was measured using 6 parameters: 1) patient distress as assessed by independent blinded observers after videotape review using the OSBD-r; 2) orthopedic satisfaction score (Likert scale 1-5); 3) sedation nurse satisfaction score (Likert 1-5); 4) parental perception of procedural pain using a 0 to 100 mm Visual Analog Scale with the upper limit being "most pain"; 5) patient recall of the procedure; and 6) 1 to 3 week follow-up. RESULTS: RT and total sedation time were significantly less in the P/F group than in the K/M group (33.4 minutes vs 23.2 minutes). The mean OSBD-r scores during manipulation were 0.084 and 0.278 for the K/M and P/F groups, respectively. Although this difference was statistically significant (95% confidence interval for the mean difference -0.34 to -0.048), both regimens were successful in keeping the scores low. There was no statistical difference between the groups in the other measures of effectiveness. There was a statistically significant difference between the groups in the occurrence of desaturation and late side effects. CONCLUSIONS: RT with P/F is shorter than with K/M. P/F is comparable to K/M in reducing procedural distress associated with painful orthopedic procedures in the pediatric emergency department. Although propofol has a greater potential of respiratory depression and airway obstruction as compared with ketamine, it offers some unique advantages including a quicker offset and smoother recovery profile.

Management of antiphospholipid antibody positivity and elective orthopedic procedures.

Current management of primary or secondary antiphospholipid antibody (aPL) syndromes with known embolic phenomena requiring anticoagulation is empiric in the setting of elective orthopedic procedures. Short-term withdrawal of warfarin with continuance of aspirin and glucocorticoid therapy was undertaken for sequential bilateral knee replacements in a lupus patient with aPL. Her course was successfully managed without thrombo-embolic complications.

Human immunodeficiency virus testing for elective orthopedic procedures: results in a community-based hospital.

Between January 1, 1989 and July 31, 1995, voluntary preoperative screening tests for human immunodeficiency virus (HIV) infection, using an enzyme-linked immunosorbant assay, were completed on 2,727 patients who underwent elective orthopedic surgical procedures. There were 2,719 (99.7%) negative, 4 (0.15%) positive, and 3 (0.11%) false-positive results; 1 test was indeterminate (0.04%). All 4 positive patients were men with a mean age of 32 years (range: 26-43 years). Although the prevalence of positive tests is low in this setting, voluntary testing alerts the surgeon to higher risk patients, does not sacrifice patient care, and enables the incorporation of more extensive precautionary measures in the operating room to minimize occupational risks to the surgical team.
