Abstract

Background: Blockbuster Laryngeal mask airway (LMA) is a device gaining popularity in airway management, and advantageous in ventilation and intubation. Air Q LMA is a supraglottic airway device with a shorter and wider breathing tube designed for ventilation as well as intubation in difficult airway. We aimed to evaluate the success of tracheal intubation using these devices.Methods: Overall 80 participants aged 18-60 years with ASA I and II were randomized into Group A (Air Q LMA) and Group B (Blockbuster LMA) using computer generated random numbers. The objectives of our study were to evaluate first pass successful intubation, ease, time and attempts taken for device insertion, oropharyngeal leak pressure, time for LMA removal and post operative complications. Association between variables were assessed with chi square test and unpaired t test.Result: There was a statistically significant difference in the first pass successful intubation between the groups which was higher in Group B (90%) than Group A (60%) (P<0.001), the overall successful intubation was more in Group B 97.5% compared to Group A 85%. The device insertion was easy in 85% patients in Group A and 95% patients in Group B. The time taken for introduction of Air Q was longer (38.15±4.92sec) when compared with blockbuster LMA (26.25±4.44sec), (P<0.001).  Mean Oropharyngeal leak pressure of blockbuster LMA (32.40±3.99cmH2O) was greater than Air Q LMA (29.10±2.61cmH2O), (P<0.001).Conclusion: Blockbuster LMA provides greater success of blind tracheal intubation when compared to air Q LMA.

Abstract

Background: Phenylephrine and ephedrine are widely used to manage spinal-induced hypotension after cesarean section. Norepinephrine is an alternative vasopressor that maintains the heart rate. This study compared the efficacy and safety of bolus administration of norepinephrine, phenylephrine, and ephedrine for treating post-spinal hypotension during elective cesarean section.Methods: This prospective, randomized, double-blind controlled trial included patients between 20–45 years of age undergoing elective cesarean section; they were randomized into three groups receive norepinephrine 6 µg (Group A, n = 45), phenylephrine 100 µg (Group B, n = 45), or ephedrine 6 mg (Group C, n = 45) boluses after a 20% drop in blood pressure. The primary objective was to compare the efficacy (total doses required) and safety (maternal complications) of treating post-spinal hypotension. Secondary objectives assessed neonatal outcomes using fetal arterial blood gas and Apgar scores. Mean differences were analyzed using one-way analysis of variance at a 95% confidence level (α = 0.05).Result: The total number of drug boluses required to treat maternal hypotension was significantly lower in group A (1.78 ± 0.74) than in groups B (1.93 ± 0.69) and C (2.38 ± 0.81) (F = 7.89; p < 0.001). Tachycardia occurred more frequently in group C (37.8%) than in groups A (15.6%) and B (26.7%) (p = 0.001). The incidence of bradycardia was higher in group B (24.4%) than in groups A (20%) and C (6.7%) (p = 0.001). Maternal complications were comparable between the groups, with no significant differences in neonatal outcomes.Conclusion: Norepinephrine is a potent drug with a better hemodynamic profile than phenylephrine and ephedrine.
