Breathing pattern in weaning patients: comparison of two inspired oxygen fractions.

Background And Objectives: An inspired oxygen fraction (FiO2) of 40% is often used for weaning patients, but lower FiO2 values are also recommended, if arterial oxygen pressure (PaO2)/ FiO2 >150-200 mmHg. This study aimed to compare respiratory variables and vital data values recorded during use of sufficient FiO2 (ideal) to maintain peripheral oxygen saturation at 92% with values recorded during use of FiO2 established at 40% (baseline) in weaning patients.

Methods: Prospective cross-over study.

[Phacoemulsification with intraocular lens implantation in leprosy patients: case control study].

Purpose: To check the complications of cataract surgery with intraocular lens implantation in leprosy patients by the phacoemulsification technique, and to compare these results, with a control group.

Methods: The used method was a case control study, where 31 eyes from leprosy patients were submitted to cataract surgery, from June 1999 to January 2003, called Case Group. On the other hand, 31 eyes of healthy patients were selected for the Control Group.
