Face mask ventilation: Do muscle relaxants help?
How many times have you heard the discussion of whether to proceed with muscle relaxant administration when face mask ventilation is moderately difficult? There are pros and cons to each side, but the science suggests that muscle relaxant will not … Continue reading
Journey to the center of ventilation
In the current issue of Anesthesiology, Dr. Oliver C. Radke (Assistant Clinical Professor, San Francisco General Hospital, Department of Anesthesia & Perioperative Care, University of California San Francisco, San Francisco, California, and Senior Attending Anesthesiologist, Klinik und Poliklinik für Anästhesiologie … Continue reading
In the lab with Oliver C. Radke: turning the OR into a research lab
This “In the Lab” post is based on the article “Spontaneous Breathing during General Anesthesia Prevents the Ventral Redistribution of Ventilation as Detected by Electrical Impedance Tomography: A Randomized Trial,” authored by Dr. Oliver C. Radke (Assistant Clinical Professor, San … Continue reading
Less rather than more volume is better when ventilating patients after cardiac surgery
Most would agree that for patients with acute lung injury, tidal volumes should be low since higher tidal volumes can lead to lung trauma. Ventilation with high tidal volumes has also been shown to be a risk for lung injury. … Continue reading
Examining a Study of “Predictors and Clinical Outcomes from Failed Laryngeal Mask Airway Unique”
In the study “Predictors and Clinical Outcomes from Failed Laryngeal Mask Airway Unique™: A Study of 15,795 Patients,” published in the June issue of Anesthesiology, Dr. Satya Krishna Ramachandran (Assistant Professor, Department of Anesthesiology, University of Michigan, Ann Arbor, Michigan) … Continue reading
Ketamine: A great drug to use when the goal is to have the patient spontaneously breathing without an airway apparatus
In this month`s issue of Anesthesiology, the study “Ketamine Activates Breathing and Abolishes the Coupling between Loss of Consciousness and Upper Airway Dilator Muscle Dysfunction” is an elegant study in rats that examines ketamine`s effect on ventilation and airway muscles.  That … Continue reading
Ventilatory response to hypoxia and to opioids converge in an area of the brainstem
During hypoxia in humans, ventilation increases. This phenomenon is known as the hypoxic pulmonary response. The reflex starts through stimulation of the carotid chemoreceptors. The commissural subnucleus of the nucleus tractus solitarius (comNTS) receives most of its input from the … Continue reading
How should patients with acute lung injury be ventilated intraoperatively?
If a patient has the preoperative diagnosis of acute lung injury, how should the patient be ventilated intraoperatively? Should the FiO2 be increased or should low tidal volumes be used? In the ICU, when patients have lung injury, they are … Continue reading
Ventilation During Cardiopulmonary Resuscitation
How should ventilation occur during cardiopulmonary resuscitation? The authors studied 20 patients undergoing general anesthesia and, using a CPR face shield, ventilated them by an investigator randomly either through the mouth or nose. Ventilation occured after initiation of anesthesia and … Continue reading
Proper Ventilation of Patients During Cardiac Surgery
Intraoperatively, many ventilate patients using 10 ml/kg tidal volume. Lower tidal volumes are used to ventilate patients with acute lung injury. Does low tidal volume ventilation for patients during cardiac surgery make any difference in terms of either ventilator-associated lung … Continue reading
