Does a blunt needle ( Epimed ( ® ) ) eliminate the risk of vascular penetration during transforaminal epidural injection?
This case report discusses vascular penetration utilizing an Epimed(®) blunt needle to perform transforaminal injections in a clinical setting. This topic was previously discussed in earlier animal studies. We also reemphasize that neither negative aspiration or local anesthetic test doses are reliable techniques to ensure the safety of transforaminal epidural injections.
In the general population, in which most are free of left ventricular systolic dysfunction and restrictive diastolic filling using conventional echocardiographic parameters, left ventricular dysfunction by TDI is a powerful and independent predictor of death, especially when systolic performance and diastolic performance are considered together, recognizing their interdependency and their complex relation to deteriorating cardiac function.
