A Randomized Prospective Study To Compare Truflex Articulating Stylet Vurses Conventional Rigid Malleable Stylet As An Intubating Guide With The Macintosh Laryngoscopy During Elective Tracheal Intubation
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 1
Abstract
Background: Tracheal intubation is the most common and routinely performed procedure in any surgeries requiring general anaesthesia. The current study compares the Truflex articulating stylet with the conventional rigid malleable stylet during elective tracheal intubation with respect to intubation time, number of attempts and any complications during the procedure. Materials And Methods: It was single blinded, prospective, randomized, interventional study. After institutional ethics committee approval 160 patients were randomly allocated into 2 groups. One group with 80 subjects were intubated using Truflex articulating stylet and other group with 80 subjects were intubated using conventional rigid malleable stylet.Successful or failed intubation during first attempt was the primary objective. Total intubation time, glotticoscopy time, endotracheal tube negotiation time and any complications during procedure were the secondary objective. Statistical Analysis: Data were statistically described in terms of mean (±SD), frequencies (number of cases) and percentages where appropriate. Student t test, Fisher’s exact test, Mann–Whitney U test and Chi square test were used where appropriate. A p value of less than 0.05 was considered statistically significant. Results:In conventional stylet group, 96.3%, 2.5% and 1.3% of patients were intubated in 1, 2 and 3 attempts respectively whereas 100% subjects were intubated in first attempt by Truflex stylet. There was no significant difference in the proportion of patients between the two groups with respect to number of failed attempts at intubation (p=0.2453). Meanglotticoscopy time while using conventional stylet and Truflex stylet was 7.85 ± 0.96 seconds and 7.89 ± 0.92 seconds respectively with a p value of 0.8293. There was no significant difference between the two groups with respect toglotticoscopy time. Mean endotracheal tube negotiation time using conventional stylet and Truflex stylet was 8.83 ± 1.84 seconds and 8.33 ± 0.92 seconds respectively. The endotracheal tube intubation time was significantly less in patients in whom Truflex stylet was used as compared to patients in whom conventional rigid stylet was used (p=0.0328). Average total intubation time using conventional stylet and Truflex stylet was 16.68 ± 2.74 seconds and 16.22 ± 1.82 seconds respectively. There was no significant difference between the two groups with respect to total intubation time (p=0.2095). There were no complications observed during the procedure with either of the stylets. Conclusions:The results suggest that the patients intubated using Truflex articulating stylet and or conventional stylet has no difference in terms of successful or failed intubation. The patients intubated using Truflex articulating stylet has significantly lesser endotracheal tube negotiation time compared to the patients intubated with conventional rigid malleable stylet and without much significant difference in number of attempts, total intubation time, glotticoscopy time and any complications in any stylets.
