View clinical trials related to Diaphragmatic Disorder.
Filter by:Both premature and delayed extubation prolong the duration of mechanical ventilation and the intensive care unit (ICU) length of stay and increase morbidity and mortality. Therefore, accurate prediction of postextubation distress and the early diagnosis of the causes responsible for failure of a trial of pressure support ventilation are of paramount importance to improve the outcome of mechanically ventilated patients in the ICU. This observational study is designed to test the ability of cardiac and diaphragm function assessed by bedside ultrasound to predict extubation failure within 48 h and re-intubation within 1 week after extubation.
This prospective randomized study will be carried out on 75 patients in our university hospitals presented for shoulder arthroscopy under general anesthesia and ultrasound-guided interscalene brachial plexus block. All the patients will receive ultrasound-guided interscalene brachial plexus block with injection of local anesthetic volume according to the group of the patient - Group I (25 patients): patients will receive 5 ml levobupivacaine 0.25% ISPB - Group II (25 patients): patients will receive 10 ml levobupivacaine 0.25% ISPB - Group III (25 patients): patients will receive 15 ml levobupivacaine 0.25% ISPB After ensuring adequate sensory and motor blockade, general anesthesia will be carried out. The primary outcome measurement will be the incidence of diaphragmatic hemiparesis 30 minutes after performing the block detected by US assessment of diaphragmatic excursion and the secondary outcome will be the postoperative pain scores and opioid consumption.
