What is Loss of resistance technique?

The Loss of Resistance Technique (LORT) is a method used in regional anesthesia, particularly for identifying the epidural space during catheter placement. It involves the injection of a small amount of saline or air into a needle that is inserted in the back; the practitioner feels a sudden loss of resistance when the needle enters the epidural space. This technique helps ensure accurate placement of the epidural catheter, enhancing the efficacy of pain management during procedures or labor. Proper training and technique are crucial to minimize complications and ensure patient safety.
