Comparative StudyComparison of intramuscular and epidural morphine for postoperative analgesia in the grossly obese: influence on postoperative ambulation and pulmonary function.
In a randomized double-blind study of thirty grossly obese patients undergoing gastroplasty for weight reduction, the effects of intramuscular and epidural morphine were compared as regards analgesia, ambulation, gastrointestinal motility, early and late pulmonary function, duration of hospitalization, and occurrence of deep vein thrombosis in the postoperative period. The patients were operated on under thoracic epidural block combined with light endotracheal anesthesia. A six-grade scale was devised to quantify postoperative mobilization. ⋯ Furthermore, earlier postoperative recovery of peak expiratory flow and bowel function presumably contributed to a significantly shorter hospitalization in patients receiving epidural morphine. There was no evidence of prolonged respiratory depression in this high-risk category of patients. The 99mTc -plasmin tests revealed no significant difference between the two groups.

Objective evaluation of clinical performance and correlation with knowledge.
In certifying competence of anesthesiologists who have finished residency training, knowledge and judgment are evaluated objectively using written and oral examinations. Clinical motor skills, however, are not routinely assessed by objective techniques. This implicitly assumes that knowledge and judgment correlate with performance of motor skills. ⋯ There was no correlation between scores on the skill test and knowledge test. There were institution-linked differences in the scores on the skill test, suggesting that teaching of motor skills is not uniform. The advantages of developing criteria of performance of motor skills is discussed.

The pall ultipor breathing circuit filter--an efficient heat and moisture exchanger.
The Pall bacterial filter was tested as a potential heat and moisture exchanger on a model patient, placed on a circle absorber system, and clinically. The laboratory study was conducted during mechanical ventilation at a V of 6 L/min with fresh gas inflows of 1, 3 and 6 L/min. The model patient introduced carbon dioxide into the circuitry at a rate of 200 ml/min. ⋯ The clinical study was conducted on ten adult anesthetized patients breathing through the bacterial filter and ten controls. The loss of body temperature was 0.2 degrees C when the filter was used and 1.5 degrees C when the filter was not used. Arterial blood gas tensions were within normal limits when the bacterial filter was used as a humidifier.
