Diaphragmatic Dysfunction

This prospective observational cohort study aims to evaluate the prognostic value of serial bedside ultrasound assessment of diaphragmatic function in adult patients with septic shock. Diaphragmatic excursion, thickness, and thickening fraction will be assessed using point of care ultrasound at baseline and serially during the first 72 hours of intensive care admission. Dynamic changes in these parameters will be analyzed in relation to the development of respiratory failure, need for invasive mechanical ventilation, duration of mechanical ventilation, weaning and extubation outcomes, length of ICU stay, and mortality. The study will determine whether dynamic diaphragmatic ultrasound assessment can provide an early, non-invasive predictor of respiratory failure and adverse clinical outcomes in patients with septic shock.

This prospective randomized controlled study aims to compare the effects of interscalene block, infraspinatus-teres minor interfascial plane block, and a control group on postoperative analgesia and diaphragmatic function in patients undergoing shoulder arthroscopy. A total of 120 patients will be enrolled and allocated into three groups. Postoperative pain scores, opioid consumption, rescue analgesic requirements, and diaphragmatic function will be evaluated and compared among the groups. The study seeks to determine whether the infraspinatus-teres minor interfascial plane block can provide effective postoperative analgesia with less impact on diaphragmatic function compared with interscalene block.

The objective of this this single-center prospective longitudinal study is to evaluate the incidence of diaphragmatic dysfunction after non-intubated video-assisted thoracoscopic surgery (NIVATS). Participant will be evaluated during surgery, 2 hours and 24 hours after surgery.
