BACKGROUND: The cluster approach for supraclavicular brachial plexus block (SC-BPB) can be easily performed but may result in asymmetric local anesthetic (LA) spread. The authors hypothesized that the use of a cluster approach in each of the 2 planes would achieve better 3-dimensional LA distribution than the traditional single cluster approach. OBJECTIVES: The purpose of the present study was to compare a double injection (DI) in 2 planes (one injection in each plane) with the traditional single injection (SI) cluster approach for ultrasound-guided SC-BPB...

The discovery of brown adipose tissue (BAT) in adults has sparked interest in its role as a therapeutic target in metabolic disorders. Infrared thermography is a promising way to quantify BAT; however, a standardized methodology has not been established. This study aims to establish a standardized and reproducible protocol to measure thermal response to cold in the supraclavicular area using thermographic imaging. In Phase 1, we compared the thermal response to 12 °C cold after acclimation at either 32 °C or room temperature using thermographic imaging...

Background: Obesity and its metabolic consequences are a major cause of morbidity and mortality. Brown adipose tissue (BAT) utilises glucose and free fatty acids to produce heat, thereby increasing energy expenditure. Effective evaluation of human BAT stimulators is constrained by current standard BAT assessment methods as positron emission tomography-computed tomography (PET-CT) requires exposure to high doses of ionising radiation. Infrared thermography (IRT) is a potential non-invasive, safe alternative, although direct corroboration with PET-CT has not previously been established...

Both arthroscopic and open surgery of the shoulder are associated with significant postoperative pain. Use of opioids can result in adverse systemic effects, so a multi-modal analgesic approach and complementary analgesic techniques should be considered to minimize the postoperative opioid requirement. Single shot interscalene block provides effective pain control of early and limited duration which can be extended with a catheter. Continuous interscalene block should be considered for more invasive shoulder procedures...

Identification of root avulsions is of critical importance in traumatic brachial plexus injuries because it alters the reconstruction and prognosis. Pre-operative magnetic resonance imaging is gaining popularity, but there is limited and conflicting data on its diagnostic accuracy for root avulsion. This cohort study describes consecutive patients requiring brachial plexus exploration following trauma between 2008 and 2016. The index test was magnetic resonance imaging at 1.5 Tesla and the reference test was operative exploration of the supraclavicular plexus...

Cold exposure is necessary to activate human brown adipose tissue (BAT), resulting in heat production. Skin temperature is an indirect measure to monitor the body's reaction to cold. The aim of this research was to study whether the most used equations to estimate parameters of skin temperature in BAT-human studies measure the same values of temperature in young lean men (n = 11: 23.4 ± 0.5 years, fat mass: 19.9 ± 1.2%). Skin temperature was measured with 26 ibuttons at 1-minute intervals in warm and cold room conditions...

Breast cancer recurrence represents a challenge for clinicians because the management is not standardized and usually requires a multidisciplinary approach. This is the key for a good long term disease control and for a management with curative intent. The local recurrence in breast cancer appears after breast conserving treatment (BCT) or after mastectomy, and the regional recurrence involves the ipsilateral axillary, internal mammary or supraclavicular lymph nodes. Local recurrence prognosis after BCT seems to be better than after mastectomy regarding distant metastases occurrence and overall survival...

Background: Supraclavicular nerve block is a popular approach for anaesthesia for upper limb surgeries. Conventional methods for evaluation of block success are time consuming and need patient cooperation. The aim of this study was to evaluate whether the perfusion index (PI) can be used to predict and provide a cut-off value for ultrasound-guided supraclavicular nerve block success. Methods: The study included 77 patients undergoing elective orthopaedic procedures under ultrasound-guided supraclavicular nerve block...

BACKGROUND: First rib resection is a surgical treatment for decompressing the neurovascular structures in thoracic outlet syndrome (TOS). Historically, extrathoracic approaches have used a posterior, supraclavicular, or transaxillary incision to remove the first rib. In this report, we demonstrate video-assisted thoracoscopic surgery for intrathoracic first rib resection (VATS-IFRR). METHODS: Between 2009 and 2014, eight patients underwent VATS-IFRR for TOS. Surgery was performed through two 5-mm ports and one 10-mm port...

A 73-year-old woman was scheduled for brachial shunt surgery. She received regional anaesthesia of the right brachial plexus via a supraclavicular approach. During surgery we noticed acute dyspnoea with a saturation reduction. A postoperative chest X-ray showed a high position of the right diaphragm, which was caused by a phrenic nerve blockade due to the anaesthesia. This completely disappeared within 24 hours.
