Randomized Controlled Trial Clinical Trial
Changes in end-tidal carbon dioxide during gynecologic laparoscopy: spontaneous versus controlled ventilation.
To study the changes in PETCO2 during spontaneous and controlled ventilation in patients undergoing gynecologic laparoscopy. ⋯ In view of the high PETCO2 levels, spontaneous breathing should be avoided during gynecologic laparoscopy, and ventilation to an initial PETCO2 of 4 kPa (30 mmHg) is recommended during controlled ventilation.

Swedish anesthesiology is greatly indebted to the preeminent American anesthesiologist, and first professor of anesthesiology in the world, Ralph M. Waters. It was in part because of the influence and teaching of this great pioneer that modern anesthesiology became firmly established in Sweden. ⋯ Among these were four Swedes: Olle Friberg, Eric Nilsson, Karl-Gustav Dhunér, and the author. Through these Swedish pioneers and their numerous disciples, Waters had a profound influence on the development of Swedish anesthesia. The author reports his personal memories from his contact with Ralph Waters.

To evaluate the relative contribution of general anesthesia alone and in combination with the surgical procedure to the pathogenesis of late postoperative hypoxemia. ⋯ General anesthesia in itself is not an important factor in the development of late postoperative constant and episodic hypoxemia, which instead may be related to the magnitude of trauma and/or opioid administration.
