BACKGROUND We report the first prospective sonoanatomic study in neonates with the aim to perform ultrasonographic-guided epidural catheter placement in this age group. METHOD One hundred forty-five neonates with a body weight < or =4 kg (0.53-4 kg) were included in this prospective study. The study was divided into 3 consecutive parts. In the first part, the neuraxial sonoanatomy of 60 neona...

The sampling of cerebrospinal fluid (CSF) for chemical analysis is usually performed by a freehand lumbar puncture in routine clinical procedure, while the suboccipital region used postmortem examinations. We introduce new application semiautomated robotic, computed tomography (CT)-guided needle placement and CSF sampling. Postmortem (PMCT) imaging was performed, data were sent to custom-made V...

A healthy man developed cauda equina syndrome after uneventful combined spinal and epidural anesthesia. No pre-existing neurologic disorder was recorded. There was no pain or paresthesia during needle placement, drug injection or catheter insertion. The sensory levels were improved within a few days following the deficit but little improvement on motor power but not on sphincter tone. Local ane...

UNLABELLED The treatment of sacral insufficiency fractures remains an area of active investigation and development, which has typically concentrated on the lateral elements of the sacrum and the sacral ala. Although these fractures frequently involve the first sacral (S1) vertebral body, this structure has eluded a successful technique to accurately access its central portion for percutaneous c...

Spinal Hematoma The actual incidence of neurologic dysfunction resulting from hemorrhagic complications associated with neuraxial blockade is unknown; however, the incidence cited in the literature is estimated to be less than 1 in 150,000 epidural and less than 1 in 220,000 spinal anesthetics (Tryba 1993). In a review of the literature between 1906 and 1994, Vandermeulen et al. (Vandermeulen 1...

PURPOSE To quantify needle placement accuracy of magnetic resonance image (MRI)-guided core needle biopsy of the prostate. MATERIALS AND METHODS A total of 10 biopsies were performed with 18-gauge (G) core biopsy needle via a percutaneous transperineal approach. Needle placement error was assessed by comparing the coordinates of preplanned targets with the needle tip measured from the intrapr...

Post spinal puncture headache (PSPH) is a well known complication of spinal anesthesia. It occurs after spinal anesthesia induction due to dural and arachnoid puncture and has a significant effect on the patient’s postoperative well being. This manuscript is based on an observational study that runs on Babol University of Medical Sciences and review of literatures about current concepts about t...

BACKGROUND/AIM Several combined spinal-epidural (CSE) anesthesia techniques have been described. This study was designed to compare the single space ("needle-through-needle") technique (SST) and the double distant space technique (DDS) with regards to the time needed for the procedure, patient discomfort during the procedure and patient's preference technique. METHODS This prospective, random...

OBJECTIVES/HYPOTHESIS There are numerous techniques for awake laryngeal injection, each with its limitations and technical challenges. We demonstrate a modification to the thyrohyoid approach for injection that stabilizes needle introduction and allows for consistent placement in a wide variety of larynges. STUDY DESIGN Retrospective review at a tertiary care institution. METHODS A retrospe...

Complementary to a previous publication related to pediatric extremity and trunk blockade, the authors present a comprehensive narrative review of the literature pertaining to techniques described and outcomes evaluated for ultrasound imaging in pediatric neuraxial anesthesia. The sonoanatomy related to each block is also described and illustrated to serve as a foundation for better understandi...
