Using psychometric ability to improve education in ultrasound-guided regional anaesthesia: a multicentre randomised controlled trial.

The learning curve for novices developing regional anaesthesia skills, such as real-time ultrasound-guided needle manipulation, may be affected by innate visuospatial ability, as this influences spatial cognition and motor co-ordination. We conducted a multinational randomised controlled trial to test if novices with low visuospatial ability would perform better at an ultrasound-guided needling task with deliberate practice training than with discovery learning. Visuospatial ability was evaluated using the mental rotations test-A. We recruited 140 medical students and randomly allocated them into low-ability control (discovery learning), low-ability intervention (received deliberate practice), high-ability control, and high-ability intervention groups. Primary outcome was the time taken to complete the needling task, and there was no significant difference between groups: median (IQR [range]) low-ability control 125 s (69-237 [43-600 s]); low-ability intervention 163 s (116-276 [44-600 s]); high-ability control 130 s (80-210 [41-384 s]); and high-ability intervention 177 s (113-285 [43-547 s]), p = 0.06. No difference was found using the global rating scale: mean (95%CI) low-ability control 53% (95%CI 46-60%); low-ability intervention 61% (95%CI 53-68%); high-ability control 63% (95%CI 56-70%); and high-ability intervention 66% (95%CI 60-72%), p = 0.05. For overall procedure pass/fail, the low-ability control group pass rate of 42% (14/33) was significantly less than the other three groups: low-ability intervention 69% (25/36); high-ability control 68% (25/37); and high-ability intervention 85% (29/34) p = 0.003. Further research is required to determine the role of visuospatial ability screening in training for ultrasound-guided needle skills.

Contemporary training methods in regional anaesthesia: fundamentals and innovations.

Over the past two decades, regional anaesthesia and medical education as a whole have undergone a renaissance. Significant changes in our teaching methods and clinical practice have been influenced by improvements in our theoretical understanding as well as by technological innovations. More recently, there has been a focus on using foundational education principles to teach regional anaesthesia, and the evidence on how to best teach and assess trainees is growing. This narrative review will discuss fundamentals and innovations in regional anaesthesia training. We present the fundamentals in regional anaesthesia training, specifically the current state of simulation-based education, deliberate practice and curriculum design based on competency-based progression. Moving into the future, we present the latest innovations in web-based learning, emerging technologies for teaching and assessment and new developments in alternate reality learning systems.

Tuberculosis – patients’ knowledge, attitudes and practices regarding their illness

OBJECTIVE: To determine tuberculosis (TB) patients’ knowledge, attitudes and practices with respect to their illness. DESIGN AND METHODS: A cross sectional study was conducted. 208 tuberculosis patients > 18 years of age who were currently receiving treatment were included. The study sample was selected from two major regional chest clinics in Trinidad. A pilot tested questionnaire was interviewer administered to each patient. RESULTS: Out of the 208 patients interviewed (response rate 65.0%), 129 were male, and 79 were female. The majority of patients had either secondary or tertiary level of education (54.8%), whereas only 43.8% had either primary level of education or none at all. Analysis revealed that TB knowledge was affected by a patient’s level of education, where persons with secondary/tertiary levels of education had a greater knowledge about TB (p<0.005). The majority (78.4%) of patients believed that they were not stigmatized; however, 191 (91.8%) patients urged for increased public awareness about TB in order to change perceptions toward the disease. The majority of patients were compliant towards their management advice, as well as taking their prescribed medications, however non- compliance was noted to be more likely in the under 50 year age group (9.8%), rather than the over 50 year age group (1.1%). CONCLUSION: Patients with at least secondary level education had better knowledge about tuberculosis than those with primary level education. Patients indicated the need for more public awareness about TB. Compliance with management (medication and attendance at clinics) was good among the majority of the patients.

Real-time ultrasound-guided spinal anesthesia in patients with a challenging spinal anatomy: two case reports.

Spinal anesthesia may be challenging in patients with poorly palpable surface landmarks or abnormal spinal anatomy. Pre-procedural ultrasound imaging of the lumbar spine can help by providing additional anatomical information, thus permitting a more accurate estimation of the appropriate needle insertion site and trajectory. However, actual needle insertion in the pre-puncture ultrasound-assisted technique remains a 'blind' procedure. We describe two patients with an abnormal spinal anatomy in whom ultrasound-assisted spinal anesthesia was unsuccessful. Successful dural puncture was subsequently achieved using a technique of real-time ultrasound-guided spinal anesthesia. This may be a useful option in patients in whom landmark-guided and ultrasound-assisted techniques have failed.
