Abstract

OBJECTIVES/HYPOTHESIS:

To evaluate the correlation between surgical instrumentation and intraoperative surgical time, postoperative hemorrhage, and associated healthcare cost for pediatric adenotonsillectomy.

STUDY DESIGN:

Retrospective chart analysis.

METHODS:

Chart data were collected from pediatric patients who underwent adenotonsillectomy from 2011 to 2013. Monopolar electrocautery, radiofrequency ablation, and PlasmaBlade instruments were compared for intraoperative surgical time and postoperative hemorrhage rate. Univariate analysis of variance (ANOVA) and χ(2) analysis was utilized to evaluate differences between instrumentation and variables. Cost analysis examining instrumentation and intraoperative anesthesia was also reviewed.

RESULTS:

A total of 1,280 patients who underwent adenotonsillectomy were evaluated. There was no significant overall difference in age, sex, or preoperative diagnosis identified between the three instrumentation groups. When examining the various instruments' effect on procedure time in minutes, univariate ANOVA demonstrated a significant difference overall among the three groups (F = 8.79; P < .001). Post-hoc pairwise comparisons identified significantly faster surgical times for monopolar cautery than either PlasmaBlade (P = .03) or radiofrequency ablation (P < .001). The difference in the number of patients who experienced a postoperative bleed by instrument was not statistically significant (χ(2) = 2.36; P = .31). After instrumentation expenses were added to anesthesia cost, the overall average costs by instrument and surgical time were estimated to be $30.04 for monopolar cautery, $246.95 for PlasmaBlade, and $244.32 for radiofrequency ablation.

CONCLUSIONS:

The ideal surgical instrumentation should be cost and time efficient with a low complication rate. Monopolar cautery was associated with a statistically significant lower intraoperative surgical time, similar postoperative hemorrhage rates, and lower operative costs when compared to radiofrequency ablation and PlasmaBlade.
