Case ReportsUltrasound-guided sciatic-femoral block for revision of the amputation stump. Case report.
The use of ultrasound in regional blocks has become increasingly used because its role as facilitator and its efficacy. Direct ultrasound visualization allows the identification of peripheral nerves, independently of the ability of obtaining sensitive or motor stimulation. ⋯ Ultrasound assistance is capable of amplifying the spectrum of uses of peripheral nerve blocks in surgical interventions on amputated limbs in situations neurostimulation cannot be used.

ReviewThe role of peripheral opiate antagonists in pain medicine and perioperative care.
Pre-clinical and clinical trials of peripheral opiate antagonists have shed new light on the effects of exogenous and endogenous opioids. ⋯ If approved these drugs may offer potential solutions to important clinical problems in pain management.

Influence of tracheal gas insufflation during capnography in anesthetized patients.
Tracheal gas insufflation (TGI) consists in injecting gas in the trachea (usually oxygen). is used in patients with acute respiratory distress syndrome (ARDS) to reduce capnometry. In Anesthesiology, the reduction in capnometry can be useful, but there are no studies on the reduction in capnometry using TGI. The objective of this study was to evaluate the changes caused by TGI on capnometry in anesthetized patients. ⋯ The use of TGI did not result in a reduction in PaCO2 or P(ET)CO2 but it altered the morphology of the capnography curve.

Randomized Controlled Trial Comparative StudyComparative study for the postoperative analgesic efficacy of 20 mL at 0.5, 0.75, and 1% ropivacaine in posterior brachial plexus block.
Arthroscopic shoulder surgeries are associated with severe postoperative pain. Among the analgesic techniques available, brachial plexus block has the best results. The objective of this study was to determine which concentration of local analgesic used in the posterior brachial plexus block provides longer postoperative analgesia. ⋯ This study demonstrated that posterior brachial plexus block provides effective analgesia for shoulder surgeries. Twenty milliliters of ropivacaine in the different concentrations used in this study promoted similar analgesia.

Incidence and prophylaxis of nausea and vomiting in post-anesthetic recovery in a tertiary teaching hospital.
Postoperative nausea and vomiting (PONV) is frequent and potentially a severe complication that increases the length of anesthetic recovery and causes patient dissatisfaction. The evaluation of the risk of PONV and institution of prophylactic measures aiming the well-being of patients and cost reduction are frequent in the medical literature. This observational study evaluated the incidence, risk factors, and adjustment and effectivity of the prophylaxis of PONV in the recovery room of a tertiary teaching school. ⋯ The concerns of the anesthesiologists of the institution with PONV were evident. However, the absence of correlation between risk and prophylaxis suggests an empirical and ineffective procedure. Factors that were not evaluated were suggested by the absence between PONV and the use of antiemetic drugs. The orientation for anesthesiologists regarding more effective prophylactic measures can improve care of the population assisted.
