Study in Porcine ovary
• In the bipolar groups, the 70w power setting caused significantly more tissue damage than the 50w ones (P<0.05)
• However, at 70W setting, the duration of puncture (10s, 15s and 20s) did not make any difference to the amount of tissue damage
Energy (J) = power (W) x duration (s) x nb. punctions
A prospective dose-finding study of the amount of thermal energy required for laparoscopic ovarian diathermy S.A.K.Amer, T.C.Li and I.D.Cooke Hum Reprod 2003
A standardized monopolar coagulation current set at 30 W was applied for a duration of 5 s per puncture, giving a total thermal energy of 150 J (30X5) per puncture.
