Randomized Controlled Trial
Peristaltic pneumatic compression of the legs reduces fluid demand and improves hemodynamic stability during surgery: a randomized, prospective study.
Perioperative fluid restriction might be beneficial in specific clinical settings. In this prospective, randomized and blinded study, we assessed whether peristaltic pneumatic compression of the legs can support restrictive fluid management strategies by reducing intraoperative fluid demand and improving hemodynamic stability. ⋯ This study demonstrates that peristaltic pneumatic compression of the legs significantly improves hemodynamic stability and reduces fluid demand during minor surgery.

Nitrous oxide diffusion and the second gas effect on emergence from anesthesia.
Rapid elimination of nitrous oxide from the lungs at the end of inhalational anesthesia dilutes alveolar oxygen, producing "diffusion hypoxia." A similar dilutional effect on accompanying volatile anesthetic agent has not been evaluated and may impact the speed of emergence. ⋯ Elimination of nitrous oxide at the end of anesthesia produces a clinically significant acceleration in the reduction of concentrations of the accompanying volatile agents, contributing to the speed of emergence observed after inhalational nitrous oxide anesthetic.

Previous studies have reported a greater frequency of sensitization to latex in the female population and a higher incidence of anaphylactic reactions to latex during cesarean section. In this study, the authors investigated the prevalence of latex sensitization in obstetric patients compared with nonpregnant subjects. ⋯ The authors report a higher prevalence of latex sensitization in the obstetric population than in nonpregnant subjects undergoing gynecologic surgery.
