Ultrasound-guided Multiple Nerve Blocks: A Safe and Effective Anesthetic Modality in Geriatric Hip Fracture Patients.

Objectives: The aim was to compare the feasibility of ultrasound-guided multiple nerve blocks (fascia iliaca compartment block+sacral plexus block+superior cluneal nerve block) with general anesthesia in geriatric hip fracture patients.

Methods: Ninety-four patients were randomly divided into 2 groups: group N received ultrasound-guided multiple nerve blocks and group G received general anesthesia. Primary outcome measures included perioperative Pain Threshold Index (PTI) and Numerical Rating Scale.

Clinical application of a novel developed pressure bladder indicator in lumbar epidural puncture.

Study Objective: A novel pressure bladder indicator was developed, and this study aimed to evaluate the clinical application of the pressure bladder indicator by measuring the epidural space pressure and bladder working pressure on patients undergoing lumbar epidural puncture.

Design: Randomized, prospective, double-blinded study

Patients: 130 patients

Setting: The Second Hospital of Shandong University

Interventions: In this study, 60 patients undergoing surgical procedures under lumbar epidural anesthesia were enrolled to detect epidural pressure, and other 70 patients who were undergoing lumbar epidural anesthesia or combined spinal-epidural anesthesia were enrolled to evaluate the pressure bladder indicator.

Measurements: After successful breakthrough of ligamentum flavum by traditional methods, a pressure transducer was connected to an epidural needle tail and a monitor to measure the epidural pressure at L1-L5 in 60 patients.
