Cement Burn of the Skin Following Total Knee Arthroplasty Case Report and Review of the Literature [Case Report]

Abola, Matthew V; Mahure, Siddharth A; Schwarzkopf, Ran; Tress, Vladimir
INTRODUCTION/BACKGROUND:Cement burns following arthroplasty pro-cedures are a rare but serious complication. To the authors' knowledge, this report is the first of its kind in total knee arthroplasty. CASE/METHODS:A 61-year-old female underwent an otherwise rou-tine left total knee arthroplasty. On postoperative day one, a 3 cm by 3 cm cement burn was noted on the distal aspect of the popliteal fossa of the operative leg. The burn was noted to be a full-thickness (third degree) burn that required plastic surgery burn service management and limited the patient's postoperative recovery and function. CONCLUSIONS:Cement burns of the skin following total joint arthroplasty are rare, though when they do occur, they can cause significant pain and distress. Recognizing the depth of the skin involvement is important to determine the burn classification, treatment, and ultimately the prognosis to optimize outcomes.

STUDY OBJECTIVE: To determine whether sampling of blood from different sites influences laboratory results. DESIGN: Prospective, double-blind study. SETTING: University-affiliated hospital in Israel. PATIENTS: 100 ASA physical status I, II, and III patients undergoing major orthopedic or colon surgery (total hip and revision of total hip replacement, colon resection, or radical cystectomy). MEASUREMENTS: Blood was sampled simultaneously for hemoglobin, electrolytes, glucose, pH, blood gases, and lactate from three sampling sites (peripheral vein, central vein, and radial artery) at 5 time frames (after induction of anesthesia [baseline], one hr after induction of anesthesia, at the end of surgery, after one hr in the recovery room, and 4 hrs after surgery). At the same time points, recorded rectal temperature, mean arterial pressure, heart rate, and central venous pressure were recorded. Anesthesia, monitoring, and dwell volumes before sampling were standardized. MAIN RESULTS: There were no significant differences between the results of hemoglobin, electrolytes, glucose, pH, and blood gases obtained from different sampling sites and at different time frames. Lactate level (mmol/L) was higher in peripheral venous blood than it was in either the central vein or radial artery (<0.05), and higher in central venous blood compared with arterial blood (P < 0.05; 2.04 +/- 1.16, 1.74 +/- 0.78, and 1.54 +/- 0.68, respectively). CONCLUSION: Under stable hemodynamics and in the absence of hypothermia, serum lactate level was higher in peripheral venous blood than it was in the central vein or radial artery
