摘要:

A method for routine determination of colloid osmotic pressure (COP) in the clinical laboratory is described. A transducer membrane system is utilized in which the colloid osmotic pressure (COP) of fresh or refrigerated plasma or albumin is compared to that of isotonic saline. The measurement is completed within an average period of less than four minutes. Duplicate measurements demonstrated high reproducibility (r = >.95) and reference measurements obtained over a period of ten months were consistently within a range of 1 torr. Heparin in excess of 200 units/ml delayed equilibration. Values obtained in normal ambulatory and supine subjects conform closely to those previously reported.

摘要:

Chaotic atrial mechanism (CAM) is a serious arrhythmia occurring in elderly patients with advanced heart disease, and appears to be related to multifocal atrial activity. The properties of CAM suggest it is an automatic ectopic rhythm, and may be produced under different combinations of conditions. CAM may progress to atrial fibrillation, just as ventricular tachycardia may lead to ventricular fibrillation. Drug-enhanced automaticity, distension of atrial walls, ischemic heart disease, or space-occupying lesions accounted for our cases. These appear to be similar to the currently accepted responsible events for pathologic ventricular automaticity. Both CAM and the ectopic automatic ventricular rhythms are associated with a high mortality, since both occur in patients with advanced heart disease.The additive antiarrhythmic action of combined propranolol and quinidine therapy may be helpful in managing CAM.

摘要:

Flexible fiberoptic bronchoscopy was evaluated in 71 procedures in 55 patients. Two-thirds of these procedures were carried out in patients with ongoing mechanical ventilation as their respiratory failure contraindicated rigid bronchoscopy. A wide variety of important diagnostic information was obtained. FFB caused no mortality or serious complications. Transient tachycardia occurred in several patients, cardiac arrhythmia in two and mediastinal emphysema in one patient. Retained secretions and atelectasis were the indications for 53 FFBs; 43 (81%) of these procedures were successful in improving aeration as evaluated with radiography.

摘要:

Bleeding was controlled in seven of eight cases of massive gastrointestinal hemorrhage secondary to stress ulcers with the use of intraperitoneal norepinephrine infusions. This bleeding was unresponsive to other therapy. The procedure is simple to perform and does not require specialized personnel. With the catheter in place, the infusion may be restarted if bleeding recurs.

摘要:

Of 99 infants treated for hyaline membrane disease (HMD) by artificial ventilation during the period of 1967 to 1970 in the neonatal ICU: six died during the follow-up period, four of whom had severe neurological damage; 13 were lost to follow-up examinations; 80 were followed for two to five years.Of the 80 who were followed; 39 (48%) developed normally, 29 (36%) had problems of moderate severity with acceptable handicaps; 12 (15%) had severe neurological damage.There was a good correlation between neonatal neurological status and subsequent clinical outcome. The correlation between the neonatal EEG and clinical outcome was also good. Babies with severe neurological abnormalities during the neonatal period were found to have a high incidence of late sequelae.
