Brief summary

Epidural placement is a commonly used procedure for pain management during labor, delivery, and surgeries. However, epidural placement is often considered a technically challenging and complex procedure that requires a high level of skill and experience. In cases where the epidural is improperly placed or fails to produce effective analgesia, the discomfort and distress experienced by the patient may be heightened. Hence, the use of predictors, such as sonographic ones, may prove to be a valuable tool for healthcare professionals in the placement of epidurals, ultimately ensuring successful pain management for patients. The present study aims to identify predictors of difficult epidural placement in patients undergoing surgery.

Interventions

OTHERData collection

Several data will be collected such as: Age, weight, height, gender, previous spine surgery, skoliosis (Y/N), palpable spinous process (Y/N), experience in years of anesthesiologist, spine level of epidural placement and the following sonographic parameters at the level of epidural placement: skin-spinous process distance (cm), skin-transversous process distance (cm), erector spinae plane distance (cm), superior to inferior spinous process distance (cm)
