The study is based on the fact that a lower volume of local anesthetic drugs for ultrasound-guided supraclavicular brachial plexus block is useful for upper limb surgeries lasting for a shorter duration, and result in a lower incidence of complications. ⋯ The onset of sensory and motor block of 20 mL of 0.5% ropivacaine is comparable to 35 mL of 0.5% ropivacaine for supraclavicular brachial plexus block for upper limb surgery. There was a 21% decrease in the duration of analgesia with a decrease in volume of 0.5% ropivacaine from 35 mL to 20 mL.

Supraclavicular brachial plexus block offers good operating conditions with limited postoperative analgesia. Magnesium sulfate (MgSO4) and ketamine block peripheral nociception mediated via N-methyl-D-aspartate receptors. ⋯ The addition of MgSO4 to ropivacaine in supraclavicular brachial plexus block significantly prolongs the duration of analgesia. MgSO4 improves the quality of postoperative analgesia with lesser incidence of side effects when compared to ketamine.

The postoperative settings in cardiothoracic intensive care unit (ICU) patients pose a certain risk with pulmonary dysfunction causing morbidity and mortality. Lung ultrasound (LUS) has a potential to supplant or replace Chest X-rays (CXR) in these subset of patients, who will require bed side pulmonary pathology diagnosis and interventions. ⋯ LUS can effectively replace CXR with reduction in radiation exposure in the immediate postoperative period and also in the follow up period. It can be used as a bedside diagnostic and monitoring tool in postoperative cardiothoracic and ICUs for diagnosing pneumothorax, pleural effusion, atelectasis and interstitial edema.

The study is aimed to compare the efficacy of I-gel and ProSeal laryngeal mask airway (PLMA) in nonparalysed anesthetized individuals following manufacturer-recommended digital insertion. ⋯ The time required for digital insertion of PLMA and I-gel in nonparalyzed anesthetized patients is similar but PLMA forms a better oropharyngeal seal. I-gel is better positioned over the laryngeal framework and esophagus. I-gel allows easier passage of Ryle's tube through its drain channel than PLMA. The incidence and severity of postoperative sore throat and hoarseness was higher with PLMA.

There is no consensus regarding the concentration of dextrose supplementation to be used in pediatric patients intraoperatively. ⋯ Use of RL with 2% dextrose as intraoperative maintenance fluid in infants resulted in significant increase in blood sugar levels as compared to addition of 1% dextrose although the incidence of hyperglycemia remained comparable in both groups.
