results the mean duration of esophagectomy was 70 minutes and the total operation 180 minutes. the mean amount of bleeding during surgery was 250 cc. conversion to open approach occurred only in one patient out of 15. no cases of anastomotic leakage or pneumonia was observed. also, no case of mortality was reported. patients and methods this is a prospective study of 15 selected patients who un...

BACKGROUND Myocardial perfusion SPECT (MPS) traditionally requires the patient to be in the supine position, but diaphragmatic attenuation of the inferior wall reduces test specificity. The aim of this study was to assess the feasibility of combined MPS in the supine and prone positions using a novel cadmium zinc telluride (CZT) camera. METHODS AND RESULTS A total of 276 consecutive patients ...

We determined the effects of prolonged head-down tilt bed rest (HDT) on lung mechanics and gas exchange. Six subjects were studied in supine and upright postures before (control), during [day 113 (D113)], and after (R + number of days of recovery) 120 days of HDT. Peak expiratory flow (PF) never differed between positions at any time and never differed from controls. Maximal midexpiratory flow ...

This study aimed to examine the effects of room temperature and body position changes on cerebral blood volume, blood pressure and center-of-foot pressure (COP). Cerebral oxygenation kinetics and blood pressure were measured by near infrared spectroscopy (NIRS) and volume-compensation, respectively, in 9 males and 9 females after rapid standing from sitting and supine positions in low (12 degre...

UNLABELLED Thermoregulation interacts with cardiovascular regulation within the central nervous system. We therefore evaluated the effects of head-down tilt on intraoperative thermal and cardiovascular regulation. Thirty-two patients undergoing lower-abdominal surgery were randomly assigned to the 1) supine, 2) 15 degrees -20 degrees head-down tilt, 3) leg-up, or 4) combination of leg-up and he...

Objective The purpose of this randomized control trial with a pretest-posttest design was to compare the outcomes in one group children (n = 56) being held upright comfortable position by parent or family member during venipuncture procedures, second 51) lying flat (supine) on an exam table bed.Material and Methods three both groups were: (a) children’s behavior before, during, after procedure ...
