Peridural Anesthesia or Ultrasound-Guided Continuous 3-in-1 Block: Which Is Indicated for Analgesia in Very Elderly Patients With Hip Fracture in the Emergency Department?

Purpose: The aim of our study was to investigate the clinical relevance of preoperative acute pain management and cardiovascular stability by ultrasound-guided continuous 3-in-1 nerve block in very elderly patients with hip fracture when compared to epidural anesthesia (PDA).

Methods: To study the analgesic effect, we enrolled 37 very elderly patients with hip fractures, of whom 3 patients with dementia had to be excluded. Thus, 34 patients were randomized to 1 of the 3 groups: group A (ultrasound-guided continuous 3-in-1 block, bupivacaine; n = 10, dropout rate: 0), group B (PDA, bupivacaine; n = 14, dropout rate: 8), and group C (systemic pain therapy, piritramide/paracetamol; n = 10, dropout rate: 0).

Unilateral anesthesia does not affect the incidence of urinary retention after low-dose spinal anesthesia for knee surgery.

We evaluated whether unilateral low-dose spinal anesthesia may reduce the likelihood of postoperative urinary retention. Forty patients scheduled for knee arthroscopy randomly received bilateral (n = 20) or unilateral (n = 20) spinal anesthesia with 6-mg hyperbaric bupivacaine 0.5%.

Management of temporary urinary retention after arthroscopic knee surgery in low-dose spinal anesthesia: development of a simple algorithm.

Introduction: In practice, trauma and orthopedic surgery during spinal anesthesia are often performed with routine urethral catheterization of the bladder to prevent an overdistention of the bladder. However, use of a catheter has inherent risks. Ultrasound examination of the bladder (Bladderscan) can precisely determine the bladder volume.
