OBJECTIVE: To evaluate the feasibility and success rate of in-plane ultrasound-guided paravertebral block using laterally intercostal approach. METHODS: In the study, 27 patients undergoing elective thoracic surgery were selected to do paravertebral block preoperatively. The fifth intercostal space was scanned by ultrasound probe which was placed along the long axis of the rib and 8 cm lateral to the midline of the spine. The needle was advanced in increments aiming at the space between the internal and innermost intercostal muscles...

A system for automatically pointing ultrasound (US) imaging catheters will enable clinicians to monitor anatomical structures and track instruments during interventional procedures. Off-the-shelf US catheters provide high quality US images from within the patient. While this method of imaging has been proven to be effective for guiding many interventional treatments, significant training is required to overcome the difficulty in manually steering the imager to point at desired structures. Our system uses closed-form four degree of freedom (DOF) kinematic solutions to automatically position the US catheter and point the imager...

BACKGROUND: New catheter-over-needle (CON) technology for continuous peripheral nerve blockade has emerged, but its effect on the risk of perineural catheter tip dislocation is unknown. Less flexible catheters may be more likely to migrate away from the nerve with simulated patient movement. In the present study, we evaluated catheter tip migration between CON catheters and traditional catheter-through-needle (CTN) catheters during ultrasound-guided short-axis in-plane (SAX-IP) insertion...

The management of pain after burn injuries is a clinical challenge magnified in patients with significant comorbidities. Presently, burn pain is treated via a wide variety of modalities, including systemic pharmacotherapy and regional analgesia. Although the latter can provide effective pain control in patients with burn injuries, it is relatively underused. Furthermore, the development of ultrasound guidance has allowed for novel approaches and sparing of motor nerve blockade with preference toward sensory-specific analgesia that has not been possible previously...

OBJECTIVES: Central venous access in critically ill, small infants remains technically challenging even in experienced hands. Several vascular accesses exist, but the subclavian vein is often preferred for central venous catheter insertion in infants where abdominal malformation and/or closure of the vein preclude the use of umbilical venous catheters, as catheterization of the subclavian vein is easier in very short necks than the internal jugular vein for age-related anatomical reasons...

Patients receiving intravenous therapy require reliable venous access. Typically patients with poor peripheral access or requiring long-term treatment from an outpatient antibiotic therapy (OPAT) service need to receive secondary care input for safe central line placement, and radiological confirmation of the correct line tip placement where necessary, if treatment is to proceed as planned. Technological developments that enable accurate ultrasound-guided vein selection and electrocardiograph (ECG)-guided central line tip placement have eliminated the need for radiological or fluoroscopic confirmation of correct tip placement for peripherally placed central catheters (PICCs)...

Regional and neuraxial anesthesia for pain management after breast surgery is not widely used despite data showing improved postoperative pain control and patient satisfaction scores. We report a case of a 61-year-old woman who underwent bilateral mastectomies, and received postoperative analgesia via pectoral nerves 1 and 2 nerve blocks. This case highlights a previously undescribed technique of prolonged postoperative pain control by intraoperative placement of pectoral nerves 1 and 2 regional anesthesia catheters under direct visualization...

BACKGROUND: Pain is a major limiting factor in patient's recovery from major thoracic surgical procedures. Thoracic epidural analgesia (TEA), the current gold standard of perioperative management, has contraindications, can technically fail, and carries a risk of complications such as epidural abscess and spinal hematoma. The ultrasound-guided serratus anterior plane (SAP) block is a promising regional analgesia technique. OBJECTIVES: Since the anatomic space involved in the SAP block corresponds to the area exposed by the surgeon during right posterolateral thoracotomy, we investigated the feasibility of a "surgically guided" continuous SAP block as an alternative to TEA in selected esophagectomy patients...

Although interventional devices such as needles, guide wires and catheters are best visualized by X-ray, real-time volumetric echography could offer an attractive alternative as it avoids ionizing radiation; it provides good soft tissue contrast and it is mobile and relatively cheap. Unfortunately, as echography is traditionally used to image soft tissue and blood flow, the appearance of interventional devices in conventional ultrasound images remains relatively poor which is a major obstacle towards ultrasound-guided interventions...

BACKGROUND: The lower superior vena cava (SVC), near its junction with the right atrium (RA), is considered the ideal location for the central venous catheter tip to ensure proper function and prevent injuries. We determined catheter insertion depth with a new formula using the sternoclavicular joint and the carina as radiological landmarks, with a 1.5 cm safety margin. The accuracy of tip positioning with the radiological landmark-based technique (R) and Peres' formula (P) was compared using transoesophageal echocardiography...

BACKGROUND AND AIMS: Endoscopic ultrasound-guided drainage (EUS-GLB) is a minimally invasive option for patients with cholecystitis who are poor surgical candidates. Compared with percutaneous drainage (PC-GLB), earlier studies have demonstrated similar efficacy with improved quality of life. We present a multicenter, international experience comparing PC-GLB and EUS-GLB in nonsurgical patients with cholecystitis. METHODS: All patients who underwent either PC-GLB drainage or EUS-GLB drainage from 7 centers between January 2010 and December 2015 were included...

BACKGROUND: The introduction of routine prenatal screening using ultrasound has led to a substantial increase in diagnoses of fetal disorders that are amenable to intrauterine treatment. While an ultrasound guided insertion of small bore cannulas can be performed under local anesthesia, insertion of a fetoscope usually requires anesthetic management for the mother and the fetus. Additionally, the fetus' intrauterine position may have to be manipulated in order to enable access. Such manoeuvres depend on relaxation of the mother's abdominal wall...

BACKGROUND: Ultrasound-guided cannulation of deep mid-arm veins by a modified Seldinger (US-Seldinger) technique has been demonstrated to yield better puncture success rates and lower postoperative complication rates than direct cannulation of superficial veins near the elbow with a short peripheral cannula and peripherally inserted central catheter (PICC) insertion through the cannula (non-US conventional method). Economic factors have been evaluated across different operators (i.e. nurses, radiologists, and general practitioners) and different venous catheter types (i...
