Cardiac risks in total hip replacement.

During total hip replacement, identifiable myocardial ischemia occurs intraoperatively, indicating myocardial strain. Coronary heart disease (CHD) patients are at risk during this type of surgery. Perioperatively, CHD patients had significantly longer ST depressions than patients not suffering from CHD (3348 min vs 454 min). The number of depression episodes was also significantly higher for CHD patients (160 vs 36). Comparing the perioperative with the postoperative stage demonstrated that CHD patients experienced a highly significant shift towards shorter periods of ST-segment depression postoperatively.

Compartment syndrome secondary to prolonged intraosseous infusion.

Intraosseous infusions are a valuable means of establishing intravascular access in pediatric emergencies. We report a case of compartment syndrome from prolonged intraosseous infusion (53 hours). We postulate that chemical irritation from medications, infections, the tenuous nature of intraosseous infusions, and the use of infusion pumps may all play a role in the development of compartment syndrome. We recommend that, when possible, intraosseous lines be used only temporarily until more permanent vascular access is established, that lines that do not flow with gravity be removed, and that drugs known to cause chemical burns be used with caution. In addition, the use of x-ray and hourly measurement of leg circumference may help to determine whether a line is still in place. Also, given the changing circumstances and technology under which intraosseous infusions are used, new prospective studies of their complications are needed.
