background nowadays percutaneous nephrolithotomy (pcnl) is performed in prone and supine positions. physiologic solutions should be used to irrigate during pcnl. irrigation can cause hemodynamic, electrolyte and acid-base changes during pcnl. objectives the current study aimed to compare the electrolyte, hemodynamic and metabolic changes of prone and complete supine pcnl. patients and methods i...

conclusion safety-related parameters of posterolateral and posterior approaches in supine thoracentesis are far better than that of the conventional lateral approach. background in patients who have difficulty sitting, thoracentesis is attempted in a supine position via lateral approach. recently, a new table has been designed for supine thoracentesis. this table has gaps that allow access to t...

Abstract Introduction This study assessed the frequency and duration of arousal responses associated with posture shifts during sleep time taken to resume following versus without a supine-avoidance alarm. Method Sleep shift outcomes baseline in-home (Embletta MPR plus an inactive alarm device) subsequent after 6-8 weeks treatment were examined in 66 patients supine-predominant OSA. A technicia...

PURPOSE To determine whether the handheld dynamometer (HHD) is an appropriate tool to assess and quantify peak hip extension strength in prone standing position by (1) evaluating the concurrent validity of the HHD versus an isokinetic dynamometer (IKD), (2) establishing the minimal detectable change (MDC), and (3) determining the validity of single-trial versus multi-trial measures. METHOD A ...

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...
