Forty-six patients with severe pulmonary insufficiency were prospectively studied to compare the effects of resuscitation with either crystalloid or colloid. By random number, 26 patients received RL and 20 patients received 5 per cent ALB to maintain hemodynamic stability. Groups were comparable with respect to the cause of pulmonary insufficiency, age and(More)
Pulmonary gas exchange was studied on members of the American Medical Research Expedition to Everest at altitudes of 8,050 m (barometric pressure 284 Torr), 8,400 m (267 Torr) and 8,848 m (summit of Mt. Everest, 253 Torr). Thirty-four valid alveolar gas samples were taken using a special automatic sampler including 4 samples on the summit. Venous blood was(More)
Maximal exercise at extreme altitudes was studied during the course of the American Medical Research Expedition to Everest. Measurements were carried out at sea level [inspired O2 partial pressure (PO2) 147 Torr], 6,300 m during air breathing (inspired PO2 64 Torr), 6,300 m during 16% O2 breathing (inspired PO2 49 Torr), and 6,300 m during 14% O2 breathing(More)
Postpneumonectomy pulmonary edema has become a worldwide problem. Study of data available from some of these patients implicates excessive perioperative volumes of intravenous fluid. A study done on dogs supports the clinical conclusion. The risk factors for this complication are right pneumonectomy, large perioperative fluid load, and high intraoperative(More)
At very high altitude, exercise performance in the human sojourner may depend on a sufficient hypoxic ventilatory response (HVR). To study the relationship of HVR to exercise performance at high altitude, we studied HVR at sea level and 5,400 m and exercise ventilation at sea level, 5,400 m, and 6,300 m in nine members of the American Medical Research(More)
Fifty-eight patients who were to undergo aortic reconstruction were prospectively randomized into two groups to compare the effects of perioperative fluid replacement with isotonic and hypertonic crystalloid solutions. Blood loss was replaced with packed red blood cells, and additional fluid was given as either Ringer's lactate solution (RL, 130 mEq(More)
The effects of hemodynamic resuscitation with protein-containing or balanced salt solution were studied prospectively in 29 patients undergoing abdominal aortic surgery. Blood loss was replaced with packed red cells and extracellular volume with either Ringer's Lactate (RL) or 5% albumin in Ringer's lactate (ALB). Fluids were given to maintain the pulmonary(More)
BACKGROUND The radial nerve is at risk after diaphyseal humeral fracture or surgery to repair the fracture. We hypothesized that there are no factors associated with iatrogenic radial nerve palsy and, secondarily, that there are no factors associated with traumatic radial nerve palsy or radial nerve palsy of any type. METHODS We analyzed 325 adult(More)
Nocturnal periodic breathing was studied in eight well-acclimatized subjects living at an altitude of 6,300 m [barometric pressure (PB) 350-352 Torr] for 3-5 wk and in four subjects during one night at 8,050 m altitude (PB 281-285 Torr). The measurements at 6,300 m included tidal volume by inductance plethysmography, arterial O2 saturation by ear oximetry(More)
The American Medical Research Expedition to Mt. Everest provided a unique opportunity to record 12-lead resting ECGs in one of the largest groups studied to date at extreme altitude (19 men, aged 25 to 52 years). Twelve of the 19 subjects had four recordings breathing ambient air: May, 1981, at sea level; September at base camp (5400 meters); October at(More)
