Comparison of nebulized ropivacaine (0.75%) with nebulized dexmedetomidine on the hemodynamic response on intubation in patients undergoing surgery under general anesthesia: A comparative randomized double-blind placebo-controlled study.

Background: Laryngoscopy and tracheal intubation lead to sympathetic stimulation resulting in hemodynamic fluctuations. We compared local anesthetic ropivacaine 0.75% with alpha agonist dexmedetomidine through ultrasonic nebulization for direct local action of the drug in the airway. Methods: In our randomized study, 180 patients were prospectively assigned to three groups of 60 each: group R (0.75%), group D (1 microgram/kg), and group C (control). The primary objective was to determine whether nebulized ropivacaine or nebulized dexmedetomidine can cause a reduction in stress response to laryngoscopy and intubation. The secondary objectives were to compare the hemodynamic parameters at extubation, cough response at extubation, and postoperative sore throat. Results: A total of 165 patients were analyzed. Demographically, all the groups were similar. Group R and group D were found to significantly attenuate the heart rate (HR) at intubation and extubation when compared to group C (P < 0.05). A significant reduction in mean arterial pressure (MAP) was seen (P < 0.05; group D: 90 ± 18.4 mmHg, group C: 99.5 ± 15.9 mmHg, group R: 92.4 ± 16.1 mmHg). There was a significant reduction in cough response in both groups in comparison with group C at 0 minutes (P value; group C vs group D: <.0001; group C vs group R:.01) and 5 minutes (P value; group C vs group D: <.0001; group C vs group R: <.0001). Conclusion: Preinduction topical use of ropivacaine or dexmedetomidine, through the nebulization route, effectively attenuated the pressor responses when compared to placebo.

Protocolized approach to a COVID-19 parturient undergoing a cesarean section - A case report.

The health care workers working in the operation theater (OT) face many unique challenges to deal with the corona virus disease (COVID-19) patients undergoing surgery. We hereby report the management of a COVID-19 parturient undergoing cesarean section in the dedicated COVID health center. Patient care of this special and vulnerable subset of population with least exposure of COVID-19 to health care worker was the cornerstone of the management. We have summarized some of the important precautionary measures which were taken during cesarean section to minimize exposure and genuine use of resources in this pandemic. To conclude, despite Personal Protective Equipment (PPE), precautionary measures and strategies are of utmost importance and should be opted so as to lower the virus contagion risk.
