Comparison of oxygen supplementation by nasal cannula with suction versus air insufflation without suction under drapes during monitored anesthesia care in adult cataract surgery-A randomized non-inferiority trial.

Background: Patients with multiple co-morbidities undergoing cataract surgery are at risk of hypoxia and hypercarbia secondary to the rebreathing of the accumulated carbon dioxide under the surgical drapes. They are also at risk of fire accidents due to the hyperoxic condition secondary to oxygen supplementation.

Objectives: The main aim of the study was to determine the lowest level of hemoglobin oxygen saturation while providing medical air in comparison with oxygen.

Comparison of the analgesic efficacy of intra-articular steroid injections and its combination with suprascapular nerve block for adhesive capsulitis of the shoulder joint: a randomized clinical trial.

Background: Adhesive capsulitis is a distressing ailment that progressively limits the active and passive mobility of the shoulder joint. Physical therapy (PT) combined with intra-articular steroid (IAS) injection and suprascapular nerve block (SSNB) has shown improved functional outcomes. We aimed to assess whether providing both IAS injection and SSNB improved outcomes compared with IAS injection alone.

Comparison of ultrasonographic measurement of gastric antral volume and pH with or without pharmacological acid aspiration prophylaxis in low-risk surgical patients - A randomized clinical trial.

Background And Aims: The role of preoperative pharmacological prophylaxis in preventing aspiration pneumonitis under general anesthesia (GA) in patients at low risk of aspiration pneumonitis is still under debate. We addressed the need for routine pharmacological aspiration prophylaxis in at-risk population by assessing the change in gastric volume using ultrasound with and without pharmacological acid aspiration prophylaxis.

Material And Methods: A single-center, randomized double-blinded trial, with 200 adult patients scheduled for elective surgical procedures under GA, were randomized into a prophylaxis group, in which the patients received oral famotidine and metoclopramide, and a no prophylaxis group, in which the patients did not receive any prophylaxis.
