A Pilot Randomized Comparative Study of Two Diathermy Power Settings for Monopolar Microdissection and Bipolar Hemostasis during Tonsillectomy / 대한이비인후과학회지
The 92 patients were randomized equally into two study groups. The mean operation duration for the 15W group was significantly longer than in the 25W group (18.5±6.11 versus 13.4±6.04 minutes, p<0.01). The rate of minimal hemorrhage (defined as an episode of bleeding not significant enough for hospital visitation) for the 15W group was significantly higher than for the 25W group (41.3% versus 20.5%, p<0.05). No significant intergroup difference was observed between the rates of primary or secondaryhemorrhage or postoperative pain scores.
