Ventilator associated pneumonia is one the most common nosocomial infection encountered in the ICU patients. Despite of the implementation of the VAP prevention bundle, the incidence remains high. This can be attributed to the peritubal leak and the aspiration of the oropharyngeal secretions. The secretions further forms a nidus for the growth of organisms in the lower respiratory tract. In this study, a specialised tube, named 'suction above cuff endotracheal tube' is used, which has an additional suction port opening above the cuff. This is to facilitate timely aspiration of the secretion which pent-up above the cuff and gradually trickles down the trachea resulting in pneumonia. ⋯ In this study involving neurological population, there was no significant difference in incidence of clinical and microbiological VAP between SETT and SACETT group, when other strategies for VAP prevention were similar. Other outcomes were similar with use of either tube for intubation.

Phenylephrine(PE) bolus and infusion have been compared for post spinal hypotension and neonatal effects during cesarean section(CS) under spinal anesthesia(SA). ⋯ There was a tighter control of BP in the infusion group vs. the bolus group while the neonatal outcome was similar in both the groups.

Both intubation and extubation are associated with pressor response. ⋯ Ropivacaine when used through nebulization preinduction effectively reduced both intubation and extubation responses when compared to saline. However, there was no significant difference between the ropivacaine and lignocaine on extubation response.

Addition of glucose in the intraoperative fluid is a routine practice in infants. Under general anesthesia, due to neuroendocrine stress response, this could result in overt hyperglycemia. ⋯ Routine addition of dextrose to RL is not essential during short surgeries under general anesthesia in infants, provided preinduction blood sugar level is >70 mg/dL and intraoperative sugars are periodically monitored.

Adductor canal blocks (ACBs) have become a popular technique for postoperative pain control in total knee arthroplasty patients. Proximal and distal ACB have been compared previously, but important postoperative outcomes have yet to be assessed. ⋯ ACB performed at either proximal or distal locations shows no difference in postoperative pain measured by opioid consumption or pain scores. Better TUG performance seen in the proximal group was not statistically significant but might represent a clinically important difference in functional mobility.
