Epiduroscopy is a minimally invasive diagnostic and therapeutic technique used in patients with chronic low back pain with or without radiculopathy. Epiduroscopic procedures are particularly indicated in cases of failed spinal surgery. This review discusses the indications, contraindications, and complications of the technique, describing in detail the sacral (caudal) and interlaminar approaches and noting their advantages and disadvantages. Practical recommendations are made, along with an attempt to assess future prospects for epiduroscopy.

Central neuraxial blocks, which are associated with a low incidence of complications, are safe. When complications do occur, however, the resulting morbidity and mortality is considerable. The reported incidence of complications in all series is under 4 per 10000 patients, but given the absence of formal registries and notification procedures, which have legal implications, the real rate of occurrence of these rare events is uncertain. ⋯ When a complication occurs, factors related to the technique will have interacted with pre-existing patient-related conditions. Various scientific societies have published guidelines for managing the complications of regional anesthesia. Recently published clinical practice guidelines recommend ultrasound imaging as a useful tool in performing a central neuraxial block.

Randomized Controlled Trial Comparative Study[Ephedrine vs. phenylephrine by intravenous bolus and continuous infusion to prevent hypotension secondary to spinal anesthesia during cesarean section: a randomized comparative trial].
Subarachnoid spinal anesthesia for cesarean section is associated with a high incidence of hypotension, which can require the use of vasoconstrictors. The aim of this trial was to compare ephedrine to phenylephrine for the prevention of secondary hypotension and to assess the adverse effects on both mother and newborn. ⋯ At the doses of ephedrine and phenylephrine administered in this trial, the ability of these drugs to prevent hypotension during cesarean section proved to be similar. Higher incidences of adverse events (hypertension and bradycardia) were observed in the phenylephrine group. No differences were observed in neonatal effects.
