Randomized Controlled Trial Comparative Study Pragmatic Clinical Trial
High-flow versus standard nasal cannula in morbidly obese patients during colonoscopy: A prospective, randomized clinical trial.
Morbid obesity is associated with adverse airway events including desaturation during deep sedation. Prior works have suggested that proprietary high-flow nasal cannula devices generate positive pressure to all airway structures and may be superior to standard (low-flow) nasal cannula for prevention of desaturation. We hypothesized that, at a similar fraction of inspired oxygen (FiO2), use of a High-Flow Nasal Cannula (HFNC) at maximum flow rate would result in a lower incidence of intra-procedural desaturation episodes in morbidly obese patients compared to standard nasal cannula (SNC) during deep sedation with propofol. ⋯ At similar FiO2, HFNC was not significantly different from SNC for prevention of arterial oxygen desaturation in morbidly obese patients undergoing propofol sedation for colonoscopy.

Randomized Controlled Trial Comparative Study
Comparison of the effects of modified pectoral nerve block and erector spinae plane block on postoperative opioid consumption and pain scores of patients after radical mastectomy surgery: A prospective, randomized, controlled trial.
Breast cancer is the most common malignancy of women all over the world. In this study, we compared the effects of ultrasound-guided modified pectoral nerve (PECS) block and erector spinae plane (ESP) block on postoperative opioid consumption, pain scores, and intraoperative fentanyl need of patients undergoing unilateral modified radical mastectomy surgery. ⋯ Modified PECS block reduced postoperative tramadol consumption and pain scores more effectively than ESP block after radical mastectomy surgery.
