The attitude of anesthesiologists and anesthesiology residents of the CET/SBA regarding upper and lower limb nerve blocks.
The use of regional blocks especially peripheral nerve blocks (PNB) has been increasing in anesthesiology due to the reduced need to manage the airways, lower cost, and excellent postoperative analgesia. However, its use has restrictions due to the lack of training, that it takes longer to be done, fear of neurological complications, and systemic toxicity. The objective of this study was to measure the attitude of anesthesiologists and anesthesiology residents at Teaching and Training Centers (CET/SBA) regarding PNBs. ⋯ The questionnaire proved to be a reliable tool to measure the attitude regarding regional blocks. Anesthesiologists demonstrated greater interest for patient-related aspects, while the main focus of residents was the acquisition of technical abilities.

Botulinum toxin (BTX) is one of the most potent bacterial toxins known and its effectiveness in the treatment of some pain syndromes is well known. However, the efficacy of some of its indications is still in the process of being confirmed. The objective of this study was to review the history, pharmacological properties, and clinical applications of BTX in the treatment of pain of different origins. ⋯ Botulinum toxin type A is well tolerated in the treatment of chronic pain disorders in which pharmacotherapy regimens can cause side effects. The reduction in the consumption of analgesics and length of action of 3 to 4 months per dose represent other advantages of its use. However, further studies are necessary to establish the efficacy of BTX-A in chronic pain disorders and its exact mechanism of action, as well as its potential in multifactorial treatments.

Using the Cusum curve to evaluate the training of orotracheal intubation with the Truview EVO2 laryngoscope.
Learning curves have proved to be useful tools to monitor the performance of a worker on a new assignment. Those curves have been used to evaluate several medical procedures. The objective of this study was to evaluate the learning of orotracheal intubation (OTI) with the Truview EVO2 laryngoscope with the CUSUM learning curve. ⋯ The CUSUM learning curve is a useful instrument to demonstrate objectively the ability when performing a new task. Laryngoscopy with the Truview EVO2 in a mannequin proved to be an easy procedure for physicians with prior experience in OTI; however, one should be cautious when transposing those results to clinical practice.

Prevalence and influence of gender, age, and type of surgery on postoperative pain.
Postoperative pain is frequent despite of the therapeutic armamentarium available. Its development is related with factors inherent to the surgery and patient. The objective of this study was to evaluate the prevalence of postoperative pain in hospitalized patients and its association with gender and type of surgery. ⋯ This study demonstrated that an elevated number of patients experience pain in the first 24 hours after the surgery. The incidence of pain was higher in patients undergoing general surgery.

Randomized Controlled Trial Comparative StudyPosterior lumbar plexus block in postoperative analgesia for total hip arthroplasty: a comparative study between 0.5% Bupivacaine with Epinephrine and 0.5% Ropivacaine.
Posterior lumbar plexus block promotes effective postoperative analgesia in total knee arthroplasty. Ropivacaine and bupivacaine do not show differences in analgesic efficacy when used in different peripheral nerve blocks. The objective of this study was to compare the efficacy of postoperative analgesia resulting from the administration of a single dose of 0.5% bupivacaine or 0.5% ropivacaine in posterior lumbar plexus block for total hip arthroplasty. ⋯ 0.5% Bupivacaine and 0.5% ropivacaine produced effective and prolonged postoperative pain relief after total hip arthroplasty, without clinical differences, when equivalent doses were administered for posterior lumbar plexus block.
