Three-dimensional Laparoscopy: Does Improved Visualization Decrease the Learning Curve Among Trainees in Advanced Procedures?
Our results indicate that 3D significantly improved visualization and ability to perform complex tasks in the skills laboratory setting. This technology may be very effective in teaching advanced laparoscopic skills in the era of work-hour restrictions.
Among patients who had an out-of-hospital cardiac arrest and were found in a non-shockable rhythm the following factors were associated with a low chance of survival: no bystander CPR, non-witnessed cardiac arrest, the arrest took place at home, increasing interval between call for and arrival of ambulance, and increasing age. When these factors were considered simultaneously, groups with no survivors could be defined. In such groups the ambulance crew may refrain from starting CPR.
