Anesthesia, essays and researches

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.

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.

The use of intravenous sedation during cardiac surgery to reduce awareness has been practised routinely during past few years and the two most commonly used drugs include propofol and dexmedetomidine, but their effects on hemodynamics and postoperative outcomes in cardiac surgery is continually being evaluated. ⋯ HR and MAP were significantly less in dexmedetomidine group compared to propofol group (P < 0.05). Both the groups had a similar requirement of vasopressors and inotropes. The duration of postoperative ventilation and length of stay in the ICU were significantly shorter in the dexmedetomidine group (P < 0.05). The risk of delirium was significantly less in dexmedetomidine group (P < 0.05). From our study we concluded, that the perioperative infusion of dexmedetomidine produces better hemodynamic stability, reduces the risk of postoperative delirium, and leads to shorter ICU stay.

The spread of local anaesthetics during spinal anaesthesia is affected by various factors and can be unpredictable especially in parturients undergoing caesarean section. Factors like abdominal girth, symphysis fundal height etc have to studied to know their impact on level of sensory blockade. We hypothesized a study to find any correlation between weight of the baby and the level of sensory blockade. ⋯ There is no statistically significant correlation between weight of the baby and the level of sensory blockade.

Several video laryngoscopes had demonstrated their superiority over conventional oral and nasal intubation techniques. King Vision video laryngoscope has fewer studies supporting its suitability for oral intubations. However, its suitability as a nasal intubating device has not been yet evaluated. We evaluated the suitability of King Vision video laryngoscope for nasotracheal intubation comparing with TruviewPCD. ⋯ King Vision video laryngoscope is just as effective as TruviewPCD video laryngoscope for successful nasotracheal intubation.
