Case ReportsUse of a minimally invasive uncalibrated cardiac output monitor in patients undergoing cesarean section under spinal anesthesia: report of four cases.
Hemodynamic changes are observed during cesarean section under spinal anesthesia. Non-invasive blood pressure (BP) and heart rate (HR) measurements are performed to diagnose these changes, but they are delayed and inaccurate. Other monitors such as filling pressure and cardiac output (CO) catheters with external calibration are very invasive or inaccurate. The objective of the present study was to report the cardiac output measurements obtained with a minimally invasive uncalibrated monitor (LiDCO rapid) in patients undergoing cesarean section under spinal anesthesia. ⋯ Although this monitor had not been calibrated, it showed a tendency for consistent hemodynamic data in obstetric patients and it may be used as a therapeutic guide or experimental tool.

Update on cardiopulmonary resuscitation guidelines of interest to anesthesiologists.
The new cardiopulmonary resuscitation (CPR) guidelines emphasize the importance of high-quality chest compressions and modify some routines. The objective of this report was to review the main changes in resuscitation practiced by anesthesiologists. ⋯ Updating the phases of the new CPR guidelines is important, and continuous learning is recommended. This will improve the quality of resuscitation and survival of patients in cardiac arrest.

Can manual hyperinflation maneuvers cause aspiration of oropharyngeal secretions in patients under mechanical ventilation?
To evaluate whether manual hyperinflation maneuvers can cause aspiration of oropharyngeal secretions in patients under mechanical ventilation. ⋯ Manual hyperinflation maneuvers did not cause aspiration of oropharyngeal secretions in patients under mechanical ventilation.
