[What does the Internet teach the obstetric patient about labor analgesia?].

Background And Objectives: It has been observed a general public increased search on the Internet for health information, including Anesthesiology. The objective of this study was to evaluate the information available to the lay person in Portuguese on the Internet about labor analgesia for the Brazilian population.

Method: Using the term “labor anesthesia”, the first 20 sites found on Google in November 2014 were evaluated by two resident physicians and classified as medical and non-medical.

A scoping review of the evidence for teaching ultrasound-guided regional anesthesia.

A scoping review was performed to assess published evidence regarding how best to teach ultrasound-guided regional anesthesia (UGRA). The literature search yielded 205 articles, of which 35 met the inclusion criteria. Current literature on the topic can be divided into 3 main themes: the development of motor skills, learning and teaching sonoanatomy, and understanding of the requirements for establishing a UGRA education program and evaluation.

The epidural electric stimulation test does not predict local anesthetic spread or consumption in labour epidural analgesia.

Purpose: The epidural electrical stimulation test (EEST) is a highly specific and sensitive test for confirming placement of the epidural catheter in the epidural space. The purpose of this study was to investigate if the EEST could predict the spread and consumption of local anesthetic solutions during labour epidural analgesia.

Methods: This observational study was conducted in labouring parturients requesting epidural analgesia.

The intercristal line determined by palpation is not a reliable anatomical landmark for neuraxial anesthesia.

Purpose: The radiological intercristal line (Tuffier's line) usually intersects the spine at the L4-L5 interspace. The intercristal line determined by palpation may be used erroneously as a surrogate for the true radiological Tuffier's line. We studied term pregnant women to establish the level at which a transverse line connecting the superior aspects of the iliac crests, as determined by palpation, intersects the lumbar spine, as assessed by ultrasound.

Anesthesiologists' learning curves for ultrasound assessment of the lumbar spine.

Background And Objectives: Ultrasound assessment of the lumbar spine to facilitate neuraxial anesthesia has recently received much attention. The transfer of knowledge pertaining to this skill has never been studied. The purpose of this study was to determine the amount of teaching needed to achieve competence in spinal ultrasound.

Simulation of ultrasound-guided peripheral nerve block: learning curve of CET-SMA/HSL Anesthesiology residents.

Background And Objectives: The use of ultrasound imaging in peripheral nerve block has been increasing. However, there are few reports in the literature on the learning curve of the ultrasound technique. The objective of this report was to evaluate the learning curve of CET-SMA/HSL Anesthesiology residents of ultrasound-guided peripheral block using an experimental agar model.

The intraoperative use of warming blankets in patients undergoing radical prostatectomy is related with a reduction in post-anesthetic recovery time.

Background And Objectives: Anesthesia and the surgeries cause substantial thermal changes, and hypothermia can lead to cardiovascular complications, clotting disorders, immunologic changes, and disruption of water and electrolyte balances, besides decreasing drug metabolism and, therefore, increasing post-anesthetic recovery time (PART). Circulation of warm air (forced-air warming blanket) is the most effective non-invasive warming method currently available. The objective of the present study was to compare the time spent in the recovery room of patients undergoing radical prostatectomy with and without the intraoperative use of a forced-air warming blanket.

Pulmonary function is better preserved in pigs when acute normovolemic hemodilution is achieved with hydroxyethyl starch versus lactated Ringer's solution.

Acute normovolemic hemodilution (ANH) has been proposed to decrease the need for allogenic blood transfusion. Consequently, great amounts of fluids are necessary to maintain hemodynamics during and after blood removal. The aim of this experiment was to evaluate the oxygenation, respiratory compliance, and lung structure during ANH performed with lactated Ringer's solution and hydroxyethyl starch (HES).
