Randomized Controlled Trial Comparative Study Clinical TrialThe effect of posture on the induction of epidural anesthesia for peripheral vascular surgery.
A study was done to determine whether a difference existed in the quality and time to maximum anesthesia between the induction of lumbar epidural anesthesia in the sitting and supine position in patients undergoing infrainguinal arterial reconstruction. ⋯ When lumbar epidural anesthesia was induced in the sitting rather than supine position, the time to maximum cephalad spread was shorter and correlated directly with the height and BSA of the patient. The position of the patient during induction had no effect on the final level of cephalad spread and degree of motor block.

Randomized Controlled Trial Comparative Study Clinical TrialThoracic versus lumbar administration of fentanyl using patient-controlled epidural after thoracotomy.
Epidural fentanyl injection can provide analgesia following thoracotomy, but where to insert the catheter is a matter of debate. The study compares the effects of thoracic and lumbar patient-controlled epidural fentanyl on analgesia, fentanyl requirements, and plasma levels after thoracotomy. ⋯ The authors concluded that there is little if any advantage of thoracic over lumbar patient-controlled epidural fentanyl administration in patients after thoracotomy with respect to analgesia, fentanyl requirements, and plasma levels.

Randomized Controlled Trial Clinical TrialWrapping of the legs reduces the decrease in blood pressure following spinal anesthesia. A study in men undergoing urologic procedures.
Hypotension after induction of spinal anesthesia remains a common and a potentially serious complication despite acute expansion of intravascular volume. The current study evaluated the role of leg wrapping as an adjunct to acute volume expansion. ⋯ Tightly wrapping the legs with elastic bandages immediately after placing spinal anesthesia in mature men is a safe and efficient adjunct in preventing hypotension.

Case ReportsThe pregnant patient with an intracranial arteriovenous malformation. Cesarean or vaginal delivery using regional or general anesthesia?
A parturient with large intracranial arteriovenous malformation presented for elective cesarean delivery. ⋯ In this case report the choice of obstetric management (cesarean versus vaginal delivery) of a full-term parturient with an intracranial arteriovenous malformation is discussed, and the rationale for the preference of epidural anesthesia for the cesarean delivery is presented.
