Randomized Controlled TrialThe GlideScope facilitates nasogastric tube insertion: a randomized clinical trial.
The GlideScope (Saturn Biomedical Systems, B.C., Canada) is a reusable videolaryngoscope and is considered an effective device for tracheal intubation. We designed this study to evaluate the application of this device in nasogastric tube (NGT) insertion. ⋯ GlideScope facilitates NGT insertion and reduces the duration of the procedure.

Up-down determination of the 90% effective dose of phenylephrine for the treatment of spinal anesthesia-induced hypotension in parturients undergoing cesarean delivery.
Hypotension frequently complicates spinal anesthesia for cesarean delivery, and vasopressors are the mainstay for treatment. The most effective dose of phenylephrine for the treatment of spinal anesthesia-induced hypotension has not been estimated. ⋯ In this study, we estimated that the ED(90) of phenylephrine required to treat spinal anesthesia-induced hypotension in cesarean delivery is approximately 150 microg.

Clinical TrialThe use of the Behavioral Pain Scale to assess pain in conscious sedated patients.
Assessing pain in mechanically ventilated critically ill patients is a great challenge. There is a need for an adequate pain measurement tool for use in conscious sedated patients because of their questionable communicative abilities. In this study, we evaluated the use of the Behavioral Pain Scale (BPS) in conscious sedated patients in comparison with its use in deeply sedated patients, for whom the BPS was developed. Additionally, in conscious sedated patients, the combination of the BPS and the patient-rated Verbal Rating Scale (VRS-4) was evaluated. ⋯ The BPS is a valid tool for measuring pain in conscious sedated patients during painful procedures. Thus, for noncommunicative and mechanically ventilated patients, it may be regarded as a bridge between the observational scale used by nurses and the VRS-4 used by patients who are able to self-report pain.

Dental sedation by dentists: a view from anesthesiologists working in central Western Brazil.
Anesthesia care has been provided by diverse health professionals worldwide, but little is known about anesthesiologists' views about this. Using a survey, we sought the opinions of a group of Brazilian anesthesiologists regarding nitrous oxide/oxygen and oral minimal/moderate sedation performed by dentists. ⋯ Many anesthesiologists in Central Western Brazil do not sedate dental patients and are not confident that dentists are able to do it. Dental sedation is an issue that still needs to be clarified in this region; the respective roles of physicians and dentists need to be determined to benefit the population.

Positive intravascular test dose criteria in children during total intravenous anesthesia with propofol and remifentanil are different than during inhaled anesthesia.
The use of local anesthetic test doses is standard practice when performing regional anesthesia. When an intravascular test dose is administered during inhaled anesthesia, the heart rate does not increase in about 25% of children; altered T-wave amplitude is a better indicator. No studies have examined the criteria for a positive result during total i.v. anesthesia (TIVA) in children. ⋯ A positive test dose during TIVA is best detected by increased arterial blood pressure. Twenty-seven percent of intravascular injections were missed using heart rate criteria. T-wave amplitude is not a reliable indicator of intravascular injection during TIVA. This is in marked distinction to what is seen during inhaled anesthesia.
