Abstract:Background
Conflicting outcomes have been reported for the i-gel™ and laryngeal mask airway (LMA) ProSeal™ in children and adults during general anesthesia. Randomized controlled trials (RCTs) that yielded wide contrast outcomes between i-gel™ and LMA ProSeal™ were included in this meta-analysis.
Methods
Two authors independently identified RCTs that compared i-gel™ with LMA ProSeal™ among patients receiving general anesthesia by performing searches in EMBASE, Cochrane, PubMed, and ScienceDirect. Discussion … Show more
“…Similar to the results of our study, most previous studies on i-gel have shown first attempt success and overall insertion rates close to 90%–100%. [ 5 6 9 ] Previous study on BlockBuster™ has also claimed 96% first attempt success rates which is similar to our result. [ 6 10 ] Easier insertion and high first pass success can be possibly explained by the structural analysis of BlockBuster™, which has an inflatable cuff and an angulated (95°) airway tube which matches oropharyngeal curve and provides easy insertion without even using finger to guide the device into the mouth of the patient.…”
Background:
Supraglottic devices have revolutionized the current practice of airway management. We compared the clinical performance of a recently introduced BlockBuster™ Laryngeal mask airway with i-gel® in adult patients under general anesthesia.
Methods:
Following Institutional ethical clearance, the present study was conducted on 62 patients belonging to American Society of Anesthesiologists physical status 1 and 2 of either sex in the age group of 20–60 years under general anesthesia. Patients were randomly assigned to i-gel® (I) and BlockBuster™ (B) groups (31 per group). Time for successful insertion, insertion success rate, ease of insertion, oropharyngeal leak pressures (OLPs), and complications were assessed.
Results:
Mean insertion time of device was less in Group I (13.52 ± 2.58 s) than that of Group B (14.10 ± 2.04 s), which was neither clinically nor statistically significant (P = 0.330). OLP in Group B (24.52 ± 2.77 cm of H2O) was found to be significantly higher compared to Group I (20.81 ± 2.56 cm of H2O) with P < 0.001. Overall insertion and first attempt success was similar (i-gel® 31/31 [100%] and 29/31 [93.5%] and BlockBuster™ 31/31 [100%] and 29/31 [93.5%], respectively). Ease of insertion (P = 0.684) and complications (P = 0.782) of both the devices were comparable.
Conclusions:
Both the devices are useful and effective for airway management in adult under general anesthesia. Having a high OLP and comparable insertion time, risk of aspiration may be further reduced with the use of BlockBuster™ in comparison to i-gel®.
